The assignment and assumption agreement

The basics of assignment and assumption, filling in the assignment and assumption agreement.

While every business should try its best to meet its contractual obligations, changes in circumstance can happen that could necessitate transferring your rights and duties under a contract to another party who would be better able to meet those obligations.

Person presenting documents to another person who is signing them

If you find yourself in such a situation, and your contract provides for the possibility of assignment, an assignment and assumption agreement can be a good option for preserving your relationship with the party you initially contracted with, while at the same time enabling you to pass on your contractual rights and duties to a third party.

An assignment and assumption agreement is used after a contract is signed, in order to transfer one of the contracting party's rights and obligations to a third party who was not originally a party to the contract. The party making the assignment is called the assignor, while the third party accepting the assignment is known as the assignee.

In order for an assignment and assumption agreement to be valid, the following criteria need to be met:

  • The initial contract must provide for the possibility of assignment by one of the initial contracting parties.
  • The assignor must agree to assign their rights and duties under the contract to the assignee.
  • The assignee must agree to accept, or "assume," those contractual rights and duties.
  • The other party to the initial contract must consent to the transfer of rights and obligations to the assignee.

A standard assignment and assumption contract is often a good starting point if you need to enter into an assignment and assumption agreement. However, for more complex situations, such as an assignment and amendment agreement in which several of the initial contract terms will be modified, or where only some, but not all, rights and duties will be assigned, it's a good idea to retain the services of an attorney who can help you draft an agreement that will meet all your needs.

When you're ready to enter into an assignment and assumption agreement, it's a good idea to have a firm grasp of the basics of assignment:

  • First, carefully read and understand the assignment and assumption provision in the initial contract. Contracts vary widely in their language on this topic, and each contract will have specific criteria that must be met in order for a valid assignment of rights to take place.
  • All parties to the agreement should carefully review the document to make sure they each know what they're agreeing to, and to help ensure that all important terms and conditions have been addressed in the agreement.
  • Until the agreement is signed by all the parties involved, the assignor will still be obligated for all responsibilities stated in the initial contract. If you are the assignor, you need to ensure that you continue with business as usual until the assignment and assumption agreement has been properly executed.

Unless you're dealing with a complex assignment situation, working with a template often is a good way to begin drafting an assignment and assumption agreement that will meet your needs. Generally speaking, your agreement should include the following information:

  • Identification of the existing agreement, including details such as the date it was signed and the parties involved, and the parties' rights to assign under this initial agreement
  • The effective date of the assignment and assumption agreement
  • Identification of the party making the assignment (the assignor), and a statement of their desire to assign their rights under the initial contract
  • Identification of the third party accepting the assignment (the assignee), and a statement of their acceptance of the assignment
  • Identification of the other initial party to the contract, and a statement of their consent to the assignment and assumption agreement
  • A section stating that the initial contract is continued; meaning, that, other than the change to the parties involved, all terms and conditions in the original contract stay the same

In addition to these sections that are specific to an assignment and assumption agreement, your contract should also include standard contract language, such as clauses about indemnification, future amendments, and governing law.

Sometimes circumstances change, and as a business owner you may find yourself needing to assign your rights and duties under a contract to another party. A properly drafted assignment and assumption agreement can help you make the transfer smoothly while, at the same time, preserving the cordiality of your initial business relationship under the original contract.

Assignments: The Basic Law

The assignment of a right or obligation is a common contractual event under the law and the right to assign (or prohibition against assignments) is found in the majority of agreements, leases and business structural documents created in the United States.

As with many terms commonly used, people are familiar with the term but often are not aware or fully aware of what the terms entail. The concept of assignment of rights and obligations is one of those simple concepts with wide ranging ramifications in the contractual and business context and the law imposes severe restrictions on the validity and effect of assignment in many instances. Clear contractual provisions concerning assignments and rights should be in every document and structure created and this article will outline why such drafting is essential for the creation of appropriate and effective contracts and structures.

The reader should first read the article on Limited Liability Entities in the United States and Contracts since the information in those articles will be assumed in this article.

Basic Definitions and Concepts:

An assignment is the transfer of rights held by one party called the “assignor” to another party called the “assignee.” The legal nature of the assignment and the contractual terms of the agreement between the parties determines some additional rights and liabilities that accompany the assignment. The assignment of rights under a contract usually completely transfers the rights to the assignee to receive the benefits accruing under the contract. Ordinarily, the term assignment is limited to the transfer of rights that are intangible, like contractual rights and rights connected with property. Merchants Service Co. v. Small Claims Court , 35 Cal. 2d 109, 113-114 (Cal. 1950).

An assignment will generally be permitted under the law unless there is an express prohibition against assignment in the underlying contract or lease. Where assignments are permitted, the assignor need not consult the other party to the contract but may merely assign the rights at that time. However, an assignment cannot have any adverse effect on the duties of the other party to the contract, nor can it diminish the chance of the other party receiving complete performance. The assignor normally remains liable unless there is an agreement to the contrary by the other party to the contract.

The effect of a valid assignment is to remove privity between the assignor and the obligor and create privity between the obligor and the assignee. Privity is usually defined as a direct and immediate contractual relationship. See Merchants case above.

Further, for the assignment to be effective in most jurisdictions, it must occur in the present. One does not normally assign a future right; the assignment vests immediate rights and obligations.

No specific language is required to create an assignment so long as the assignor makes clear his/her intent to assign identified contractual rights to the assignee. Since expensive litigation can erupt from ambiguous or vague language, obtaining the correct verbiage is vital. An agreement must manifest the intent to transfer rights and can either be oral or in writing and the rights assigned must be certain.

Note that an assignment of an interest is the transfer of some identifiable property, claim, or right from the assignor to the assignee. The assignment operates to transfer to the assignee all of the rights, title, or interest of the assignor in the thing assigned. A transfer of all rights, title, and interests conveys everything that the assignor owned in the thing assigned and the assignee stands in the shoes of the assignor. Knott v. McDonald’s Corp ., 985 F. Supp. 1222 (N.D. Cal. 1997)

The parties must intend to effectuate an assignment at the time of the transfer, although no particular language or procedure is necessary. As long ago as the case of National Reserve Co. v. Metropolitan Trust Co ., 17 Cal. 2d 827 (Cal. 1941), the court held that in determining what rights or interests pass under an assignment, the intention of the parties as manifested in the instrument is controlling.

The intent of the parties to an assignment is a question of fact to be derived not only from the instrument executed by the parties but also from the surrounding circumstances. When there is no writing to evidence the intention to transfer some identifiable property, claim, or right, it is necessary to scrutinize the surrounding circumstances and parties’ acts to ascertain their intentions. Strosberg v. Brauvin Realty Servs., 295 Ill. App. 3d 17 (Ill. App. Ct. 1st Dist. 1998)

The general rule applicable to assignments of choses in action is that an assignment, unless there is a contract to the contrary, carries with it all securities held by the assignor as collateral to the claim and all rights incidental thereto and vests in the assignee the equitable title to such collateral securities and incidental rights. An unqualified assignment of a contract or chose in action, however, with no indication of the intent of the parties, vests in the assignee the assigned contract or chose and all rights and remedies incidental thereto.

More examples: In Strosberg v. Brauvin Realty Servs ., 295 Ill. App. 3d 17 (Ill. App. Ct. 1st Dist. 1998), the court held that the assignee of a party to a subordination agreement is entitled to the benefits and is subject to the burdens of the agreement. In Florida E. C. R. Co. v. Eno , 99 Fla. 887 (Fla. 1930), the court held that the mere assignment of all sums due in and of itself creates no different or other liability of the owner to the assignee than that which existed from the owner to the assignor.

And note that even though an assignment vests in the assignee all rights, remedies, and contingent benefits which are incidental to the thing assigned, those which are personal to the assignor and for his sole benefit are not assigned. Rasp v. Hidden Valley Lake, Inc ., 519 N.E.2d 153, 158 (Ind. Ct. App. 1988). Thus, if the underlying agreement provides that a service can only be provided to X, X cannot assign that right to Y.

Novation Compared to Assignment:

Although the difference between a novation and an assignment may appear narrow, it is an essential one. “Novation is a act whereby one party transfers all its obligations and benefits under a contract to a third party.” In a novation, a third party successfully substitutes the original party as a party to the contract. “When a contract is novated, the other contracting party must be left in the same position he was in prior to the novation being made.”

A sublease is the transfer when a tenant retains some right of reentry onto the leased premises. However, if the tenant transfers the entire leasehold estate, retaining no right of reentry or other reversionary interest, then the transfer is an assignment. The assignor is normally also removed from liability to the landlord only if the landlord consents or allowed that right in the lease. In a sublease, the original tenant is not released from the obligations of the original lease.

Equitable Assignments:

An equitable assignment is one in which one has a future interest and is not valid at law but valid in a court of equity. In National Bank of Republic v. United Sec. Life Ins. & Trust Co. , 17 App. D.C. 112 (D.C. Cir. 1900), the court held that to constitute an equitable assignment of a chose in action, the following has to occur generally: anything said written or done, in pursuance of an agreement and for valuable consideration, or in consideration of an antecedent debt, to place a chose in action or fund out of the control of the owner, and appropriate it to or in favor of another person, amounts to an equitable assignment. Thus, an agreement, between a debtor and a creditor, that the debt shall be paid out of a specific fund going to the debtor may operate as an equitable assignment.

In Egyptian Navigation Co. v. Baker Invs. Corp. , 2008 U.S. Dist. LEXIS 30804 (S.D.N.Y. Apr. 14, 2008), the court stated that an equitable assignment occurs under English law when an assignor, with an intent to transfer his/her right to a chose in action, informs the assignee about the right so transferred.

An executory agreement or a declaration of trust are also equitable assignments if unenforceable as assignments by a court of law but enforceable by a court of equity exercising sound discretion according to the circumstances of the case. Since California combines courts of equity and courts of law, the same court would hear arguments as to whether an equitable assignment had occurred. Quite often, such relief is granted to avoid fraud or unjust enrichment.

Note that obtaining an assignment through fraudulent means invalidates the assignment. Fraud destroys the validity of everything into which it enters. It vitiates the most solemn contracts, documents, and even judgments. Walker v. Rich , 79 Cal. App. 139 (Cal. App. 1926). If an assignment is made with the fraudulent intent to delay, hinder, and defraud creditors, then it is void as fraudulent in fact. See our article on Transfers to Defraud Creditors .

But note that the motives that prompted an assignor to make the transfer will be considered as immaterial and will constitute no defense to an action by the assignee, if an assignment is considered as valid in all other respects.

Enforceability of Assignments:

Whether a right under a contract is capable of being transferred is determined by the law of the place where the contract was entered into. The validity and effect of an assignment is determined by the law of the place of assignment. The validity of an assignment of a contractual right is governed by the law of the state with the most significant relationship to the assignment and the parties.

In some jurisdictions, the traditional conflict of laws rules governing assignments has been rejected and the law of the place having the most significant contacts with the assignment applies. In Downs v. American Mut. Liability Ins. Co ., 14 N.Y.2d 266 (N.Y. 1964), a wife and her husband separated and the wife obtained a judgment of separation from the husband in New York. The judgment required the husband to pay a certain yearly sum to the wife. The husband assigned 50 percent of his future salary, wages, and earnings to the wife. The agreement authorized the employer to make such payments to the wife.

After the husband moved from New York, the wife learned that he was employed by an employer in Massachusetts. She sent the proper notice and demanded payment under the agreement. The employer refused and the wife brought an action for enforcement. The court observed that Massachusetts did not prohibit assignment of the husband’s wages. Moreover, Massachusetts law was not controlling because New York had the most significant relationship with the assignment. Therefore, the court ruled in favor of the wife.

Therefore, the validity of an assignment is determined by looking to the law of the forum with the most significant relationship to the assignment itself. To determine the applicable law of assignments, the court must look to the law of the state which is most significantly related to the principal issue before it.

Assignment of Contractual Rights:

Generally, the law allows the assignment of a contractual right unless the substitution of rights would materially change the duty of the obligor, materially increase the burden or risk imposed on the obligor by the contract, materially impair the chance of obtaining return performance, or materially reduce the value of the performance to the obligor. Restat 2d of Contracts, § 317(2)(a). This presumes that the underlying agreement is silent on the right to assign.

If the contract specifically precludes assignment, the contractual right is not assignable. Whether a contract is assignable is a matter of contractual intent and one must look to the language used by the parties to discern that intent.

In the absence of an express provision to the contrary, the rights and duties under a bilateral executory contract that does not involve personal skill, trust, or confidence may be assigned without the consent of the other party. But note that an assignment is invalid if it would materially alter the other party’s duties and responsibilities. Once an assignment is effective, the assignee stands in the shoes of the assignor and assumes all of assignor’s rights. Hence, after a valid assignment, the assignor’s right to performance is extinguished, transferred to assignee, and the assignee possesses the same rights, benefits, and remedies assignor once possessed. Robert Lamb Hart Planners & Architects v. Evergreen, Ltd. , 787 F. Supp. 753 (S.D. Ohio 1992).

On the other hand, an assignee’s right against the obligor is subject to “all of the limitations of the assignor’s right, all defenses thereto, and all set-offs and counterclaims which would have been available against the assignor had there been no assignment, provided that these defenses and set-offs are based on facts existing at the time of the assignment.” See Robert Lamb , case, above.

The power of the contract to restrict assignment is broad. Usually, contractual provisions that restrict assignment of the contract without the consent of the obligor are valid and enforceable, even when there is statutory authorization for the assignment. The restriction of the power to assign is often ineffective unless the restriction is expressly and precisely stated. Anti-assignment clauses are effective only if they contain clear, unambiguous language of prohibition. Anti-assignment clauses protect only the obligor and do not affect the transaction between the assignee and assignor.

Usually, a prohibition against the assignment of a contract does not prevent an assignment of the right to receive payments due, unless circumstances indicate the contrary. Moreover, the contracting parties cannot, by a mere non-assignment provision, prevent the effectual alienation of the right to money which becomes due under the contract.

A contract provision prohibiting or restricting an assignment may be waived, or a party may so act as to be estopped from objecting to the assignment, such as by effectively ratifying the assignment. The power to void an assignment made in violation of an anti-assignment clause may be waived either before or after the assignment. See our article on Contracts.

Noncompete Clauses and Assignments:

Of critical import to most buyers of businesses is the ability to ensure that key employees of the business being purchased cannot start a competing company. Some states strictly limit such clauses, some do allow them. California does restrict noncompete clauses, only allowing them under certain circumstances. A common question in those states that do allow them is whether such rights can be assigned to a new party, such as the buyer of the buyer.

A covenant not to compete, also called a non-competitive clause, is a formal agreement prohibiting one party from performing similar work or business within a designated area for a specified amount of time. This type of clause is generally included in contracts between employer and employee and contracts between buyer and seller of a business.

Many workers sign a covenant not to compete as part of the paperwork required for employment. It may be a separate document similar to a non-disclosure agreement, or buried within a number of other clauses in a contract. A covenant not to compete is generally legal and enforceable, although there are some exceptions and restrictions.

Whenever a company recruits skilled employees, it invests a significant amount of time and training. For example, it often takes years before a research chemist or a design engineer develops a workable knowledge of a company’s product line, including trade secrets and highly sensitive information. Once an employee gains this knowledge and experience, however, all sorts of things can happen. The employee could work for the company until retirement, accept a better offer from a competing company or start up his or her own business.

A covenant not to compete may cover a number of potential issues between employers and former employees. Many companies spend years developing a local base of customers or clients. It is important that this customer base not fall into the hands of local competitors. When an employee signs a covenant not to compete, he or she usually agrees not to use insider knowledge of the company’s customer base to disadvantage the company. The covenant not to compete often defines a broad geographical area considered off-limits to former employees, possibly tens or hundreds of miles.

Another area of concern covered by a covenant not to compete is a potential ‘brain drain’. Some high-level former employees may seek to recruit others from the same company to create new competition. Retention of employees, especially those with unique skills or proprietary knowledge, is vital for most companies, so a covenant not to compete may spell out definite restrictions on the hiring or recruiting of employees.

A covenant not to compete may also define a specific amount of time before a former employee can seek employment in a similar field. Many companies offer a substantial severance package to make sure former employees are financially solvent until the terms of the covenant not to compete have been met.

Because the use of a covenant not to compete can be controversial, a handful of states, including California, have largely banned this type of contractual language. The legal enforcement of these agreements falls on individual states, and many have sided with the employee during arbitration or litigation. A covenant not to compete must be reasonable and specific, with defined time periods and coverage areas. If the agreement gives the company too much power over former employees or is ambiguous, state courts may declare it to be overbroad and therefore unenforceable. In such case, the employee would be free to pursue any employment opportunity, including working for a direct competitor or starting up a new company of his or her own.

It has been held that an employee’s covenant not to compete is assignable where one business is transferred to another, that a merger does not constitute an assignment of a covenant not to compete, and that a covenant not to compete is enforceable by a successor to the employer where the assignment does not create an added burden of employment or other disadvantage to the employee. However, in some states such as Hawaii, it has also been held that a covenant not to compete is not assignable and under various statutes for various reasons that such covenants are not enforceable against an employee by a successor to the employer. Hawaii v. Gannett Pac. Corp. , 99 F. Supp. 2d 1241 (D. Haw. 1999)

It is vital to obtain the relevant law of the applicable state before drafting or attempting to enforce assignment rights in this particular area.

Conclusion:

In the current business world of fast changing structures, agreements, employees and projects, the ability to assign rights and obligations is essential to allow flexibility and adjustment to new situations. Conversely, the ability to hold a contracting party into the deal may be essential for the future of a party. Thus, the law of assignments and the restriction on same is a critical aspect of every agreement and every structure. This basic provision is often glanced at by the contracting parties, or scribbled into the deal at the last minute but can easily become the most vital part of the transaction.

As an example, one client of ours came into the office outraged that his co venturer on a sizable exporting agreement, who had excellent connections in Brazil, had elected to pursue another venture instead and assigned the agreement to a party unknown to our client and without the business contacts our client considered vital. When we examined the handwritten agreement our client had drafted in a restaurant in Sao Paolo, we discovered there was no restriction on assignment whatsoever…our client had not even considered that right when drafting the agreement after a full day of work.

One choses who one does business with carefully…to ensure that one’s choice remains the party on the other side of the contract, one must master the ability to negotiate proper assignment provisions.

Chapter 12 – Third-Party Rights

12.2 Assignment of Contract Rights

Contracts create rights and obligations between contracting parties. An assignment is the transfer of rights under a contract from one party (the assignor ) to another party (the assignee ). When a party assigns their rights under a contract, they are essentially transferring their ability to receive benefits or enforce terms of the contract to someone else. Stated another way, an assignment occurs when an   obligee   (one who has the right to receive a contract benefit) transfers a right to receive a contract benefit owed by the   obligor   (the one who has a duty to perform) to a third person ( assignee ); the obligee then becomes an   assignor   (one who makes an assignment). So, the party that makes the assignment is both an obligee and an assignor. The assignee acquires the right to receive the contractual obligations of the promisor, who is referred to as the obligor.

Generally, the assignor may assign any right unless (1) doing so would materially change the obligation of the obligor, materially burden him, increase his risk, or otherwise diminish the value to him of the original contract; (2) statute or public policy forbids the assignment; or (3) the contract itself precludes assignment. The common law of contracts and Articles 2 and 9 of the Uniform Commercial Code (UCC) govern assignments. Assignments are a common occurrence in business, legal, and financial transactions.

Method of Assignment

Manifesting assent.

To effect an assignment , the assignor must make known his intention to transfer the rights to the third person. This intention must take place in the present – it cannot be a future intention. The assignor’s intention must be that the assignment is effective without need of any further action or any further manifestation of intention to make the assignment. Under the UCC, any assignments of rights in excess of $5,000 must be in writing, but otherwise, assignments can be oral and consideration is not required: the assignor could assign the right to the assignee for no exchange of money or any other consideration. For example, Mrs. Franklin has the right to receive $750 a month from the sale of a house she formerly owned; she assigns the right to receive the money to her son Jason, as a gift. The assignment is good, and need not be written.

Acceptance and Revocation

For the assignment to become effective, the assignee must manifest his acceptance under most circumstances. This is done automatically when, as is usually the case, the assignee has given consideration for the assignment (i.e., there is a contract between the assignor and the assignee in which the assignment is the assignor’s consideration), and then the assignment is not revocable without the assignee’s consent. Problems of acceptance normally arise only when the assignor intends the assignment as a gift. Then, for the assignment to be irrevocable, either the assignee must manifest his acceptance or the assignor must notify the assignee in writing of the assignment. Thus, if Mrs. Franklin assigns the $750 a month from the sale of her house to her son Jason as a gift, this assignment is valid, but revocable.

Notice to the obligor is not required, but an obligor who renders performance to the assignor without notice of the assignment (that performance of the contract is to be rendered now to the assignee) is discharged from their obligation within the contract. Obviously, the assignor cannot then keep the consideration he has received; he owes it to the assignee. But if notice is given to the obligor and she performs to the assignor anyway, the assignee can recover from either the obligor or the assignee, so the obligor could have to perform twice. Of course, an obligor who receives notice of the assignment from the assignee will want to be sure the assignment has really occurred. After all, anybody could waltz up to the obligor and say, “I’m the assignee of your contract with the bank. From now on, pay me the $500 a month, not the bank.” The obligor is entitled to verification of the assignment.

Effect of Assignment

An assignment of rights effectively makes the assignee “ stand in the shoes” of   the assignor (the “shoe rule”). He gains all the rights against the obligor that the assignor had, but no more. An obligor who could avoid the assignor’s attempt to enforce the rights could avoid a similar attempt by the assignee. Suppose Dealer sells a car to Buyer on a contract where Buyer is to pay $300 per month and the car is warranted for 50,000 miles. If the car goes on the fritz before then and Dealer won’t fix it, Buyer could fix it for, say, $250 and deduct that $250 from the amount owed Dealer on the next installment. Now, if Dealer assigns the contract to Assignee, Assignee stands in Dealer’s shoes, and Buyer could likewise deduct the $250 from payment to Assignee.

The “shoe rule” does not apply to two types of assignments. First, it is inapplicable to the sale of a negotiable instrument to a holder in due course. Second, the rule may be waived: under the UCC and at common law, the obligor may agree in the original contract not to raise defenses against the assignee that could have been raised against the assignor.     While a waiver  of defenses   makes the assignment more marketable from the assignee’s point of view, it is a situation fraught with peril to an obligor, who may sign a contract without understanding the full import of the waiver. Under the waiver rule, for example, a farmer who buys a tractor on credit and discovers later that it does not work would still be required to pay a credit company that purchased the contract; his defense that the merchandise was shoddy would be unavailing (he would, as used to be said, be “having to pay on a dead horse”).

For that reason, there are various rules that limit both the holder in due course and the waiver rule. Certain defenses, the so-called real defenses (infancy, duress, and fraud in the execution, among others), may always be asserted. Also, the waiver clause in the contract must have been presented in good faith, and if the assignee has actual notice of a defense that the buyer or lessee could raise, then the waiver is ineffective. Moreover, in consumer transactions, the UCC’s rule is subject to state laws that protect consumers (people buying things used primarily for personal, family, or household purposes), and many states, by statute or court decision, have made waivers of defenses ineffective in such   consumer transactions . Federal Trade Commission regulations also affect the ability of many sellers to pass on rights to assignees free of defenses that buyers could raise against them. Because of these various limitations on the holder in due course and on waivers, the “shoe rule” will not govern in consumer transactions and, if there are real defenses or the assignee does not act in good faith, in business transactions as well.

Prohibited Assignments

The general rule—as previously noted—is that most contract rights are assignable, and the law favors freely assignable rights. There are five exceptions to this rule however.

Material Change in Duties of the Obligor

When an assignment has the effect of materially changing the duties that the obligor must perform, it is ineffective. Changing the party to whom the obligor must make a payment is not a material change of duty that will defeat an assignment, since that, of course, is the purpose behind most assignments. Nor will a minor change in the duties the obligor must perform defeat the assignment. But, some changes are significant enough to bar assignments.

Several residents in the town of Centerville sign up on an annual basis with the Centerville   Times   to receive their morning paper. A customer who is moving out of town may assign his right to receive the paper to someone else within the delivery route. As long as the assignee pays for the paper, the assignment is effective; the only relationship the obligor has to the assignee is a routine delivery in exchange for payment. But if the change involves assigning the right to receive the paper to someone that is outside of the delivery route, that change would be material, and the assignment could be invalid.

Assignment of Personal Rights

When it matters to the obligor who receives the benefit of his duty to perform under the contract, then the receipt of the benefit is a   personal right   that cannot be assigned. For example, a student seeking to earn pocket money during the school year signs up to do research work for a professor she admires and with whom she is friendly. The professor assigns the contract to one of his colleagues with whom the student does not get along. The assignment is ineffective because it matters to the student (the obligor) who the person of the assignee is. It is for this same reason that tenants usually cannot assign (sublet) their tenancies without the landlord’s permission because it matters to the landlord who the person is that is living in the landlord’s property.

Nassau Hotel Co. v. Barnett & Barse Corporation , 147 N.Y.S. 283 (1914)

MCLAUGHLIN, J.

Plaintiff owns a hotel at Long Beach, L. I., and on the 21st of November, 1912, it entered into a written agreement with the individual defendants Barnett and Barse to conduct the same for a period of years.…Shortly after this agreement was signed, Barnett and Barse organized the Barnett & Barse Corporation with a capital stock of $10,000, and then assigned the agreement to it. Immediately following the assignment, the corporation went into possession and assumed to carry out its terms. The plaintiff thereupon brought this action to cancel the agreement and to recover possession of the hotel and furniture therein, on the ground that the agreement was not assignable. [Summary judgment in favor of the plaintiff, defendant corporation appeals.]

The only question presented is whether the agreement was assignable. It provided, according to the allegations of the complaint, that the plaintiff leased the property to Barnett and Barse with all its equipment and furniture for a period of three years, with a privilege of five successive renewals of three years each. It expressly provided:

‘That said lessees…become responsible for the operation of the said hotel and for the upkeep and maintenance thereof and of all its furniture and equipment in accordance with the terms of this agreement and the said lessees shall have the exclusive possession, control and management thereof. * * * The said lessees hereby covenant and agree that they will operate the said hotel at all times in a first-class business-like manner, keep the same open for at least six (6) months of each year, * * *’ and ‘in lieu of rental the lessor and lessees hereby covenant and agree that the gross receipts of such operation shall be, as received, divided between the parties hereto as follows: (a) Nineteen per cent. (19%) to the lessor. * * * In the event of the failure of the lessees well and truly to perform the covenants and agreements herein contained,’ they should be liable in the sum of $50,000 as liquidated damages. That ‘in consideration and upon condition that the said lessees shall well and faithfully perform all the covenants and agreements by them to be performed without evasion or delay the said lessor for itself and its successors, covenants and agrees that the said lessees, their legal representatives and assigns may at all times during said term and the renewals thereof peaceably have and enjoy the said demised premises.’ And that ‘this agreement shall inure to the benefit of and bind the respective parties hereto, their personal representatives, successors and assigns.’

The complaint further alleges that the agreement was entered into by plaintiff in reliance upon the financial responsibility of Barnett and Barse, their personal character, and especially the experience of Barnett in conducting hotels; that, though he at first held a controlling interest in the Barnett & Barse Corporation, he has since sold all his stock to the defendant Barse, and has no interest in the corporation and no longer devotes any time or attention to the management or operation of the hotel.

…[C]learly…the agreement in question was personal to Barnett and Barse and could not be assigned by them without the plaintiff’s consent. By its terms the plaintiff not only entrusted them with the care and management of the hotel and its furnishings—valued, according to the allegations of the complaint, at more than $1,000,000—but agreed to accept as rental or compensation a percentage of the gross receipts. Obviously, the receipts depended to a large extent upon the management, and the care of the property upon the personal character and responsibility of the persons in possession. When the whole agreement is read, it is apparent that the plaintiff relied, in making it, upon the personal covenants of Barnett and Barse. They were financially responsible. As already said, Barnett had had a long and successful experience in managing hotels, which was undoubtedly an inducing cause for plaintiff’s making the agreement in question and for personally obligating them to carry out its terms.

It is suggested that because there is a clause in the agreement to the effect that it should ‘inure to the benefit of and bind the respective parties hereto, their personal representatives and assigns,’ that Barnett and Barse had a right to assign it to the corporation. But the intention of the parties is to be gathered, not from one clause, but from the entire instrument [Citation] and when it is thus read it clearly appears that Barnett and Barse were to personally carry out the terms of the agreement and did not have a right to assign it. This follows from the language used, which shows that a personal trust or confidence was reposed by the plaintiff in Barnett and Barse when the agreement was made.

In [Citation] it was said: “Rights arising out of contract cannot be transferred if they…involve a relation of personal confidence such that the party whose agreement conferred those rights must have intended them to be exercised only by him in whom he actually confided.”

This rule was applied in [Citation] the court holding that the plaintiff—the assignee—was not only technically, but substantially, a different entity from its predecessor, and that the defendant was not obliged to entrust its money collected on the sale of the presses to the responsibility of an entirely different corporation from that with which it had contracted, and that the contract could not be assigned to the plaintiff without the assent of the other party to it.

The reason which underlies the basis of the rule is that a party has the right to the benefit contemplated from the character, credit, and substance of him with whom he contracts, and in such case he is not bound to recognize…an assignment of the contract.

The order appealed from, therefore, is affirmed.

Case questions

  • The corporation created to operate the hotel was apparently owned and operated by the same two men the plaintiff leased the hotel to in the first place. What objection would the plaintiff have to the corporate entity—actually, of course, a legal fiction—owning and operating the hotel?
  • The defendants pointed to the clause about the contract inuring to the benefit of the parties “and assigns.” So the defendants assigned the contract. How could that not be allowed by the contract’s own terms?
  • What is the controlling rule of law upon which the outcome here depends?

Assignment Forbidden by Statute or Public Policy

Various federal and state laws prohibit or regulate some contract assignments. For example, the assignment of future wages is regulated by state and federal law, such an attempt to try to effect such an assignment would not be valid. And even in the absence of statute, public policy might prohibit some assignments.

Contracts That Prohibit Assignment

A written contract may contain general language that prohibits assignment of rights or assignment of “the contract.” Both the Restatement and UCC Section 2-210(3) declare that in the absence of any contrary circumstances, a provision in the agreement that prohibits assigning “the contract” bars “only the delegation to the assignee of the assignor’s performance.”     In other words, unless the contract specifically prohibits assignment of any of its terms, a party is free to assign anything except his or her own duties. Even if a contractual provision explicitly prohibits it, a right to damages for breach of the whole contract is assignable under UCC Section 2-210(2) in contracts for goods. Likewise, UCC Section 9-318(4) invalidates any contract provision that prohibits assigning sums already due or to become due. Indeed, in some states, at common law, a clause specifically prohibiting assignment will fail. For example, the buyer and the seller agree to the sale of land and to a provision barring assignment of the rights under the contract. The buyer pays the full price, but the seller refuses to convey. The buyer then assigns to her friend the right to obtain title to the land from the seller. The latter’s objection that the contract precludes such an assignment will fall on deaf ears in some states; the assignment is effective, and the friend may sue for the title. Bottom line, even though a contract may expressly state it cannot be assigned, that may not always be the case.

As we saw with integration clauses, if you are a Verizon Wireless ™ customer, you have agreed to their terms regarding assignment:

You cannot assign this Agreement or any of your rights or duties under it without our permission. However, we may assign this Agreement or any debt you owe us without notifying you.

Such assignment clauses can be found in many common contracts.

Rose v. Vulcan Materials Co. 194 S.E.2d 521 (N.C. 1973)

HUSKINS, J.

…Plaintiff [Rose], after leasing his quarry to J. E. Dooley and Son, Inc., promised not to engage in the rock-crushing business within an eight-mile radius of [the city of] Elkin for a period of ten years. In return for this promise, J. E. Dooley and Son, Inc., promised, among other things, to furnish plaintiff stone f.o.b. the quarry site at Cycle, North Carolina, at stipulated prices for ten years.…

By a contract effective 23 April 1960, Vulcan Materials Company, a corporation…, purchased the stone quarry operations and the assets and obligations of J. E. Dooley and Son, Inc.…[Vulcan sent Rose a letter, part of which read:]

Mr. Dooley brought to us this morning the contracts between you and his companies, copies of which are attached. This is to advise that Vulcan Materials Company assumes all phases of these contracts and intends to carry out the conditions of these contracts as they are stated.

In early 1961 Vulcan notified plaintiff that it would no longer sell stone to him at the prices set out in [the agreement between Rose and Dooley] and would thereafter charge plaintiff the same prices charged all of its other customers for stone. Commencing 11 May 1961, Vulcan raised stone prices to the plaintiff to a level in excess of the prices specified in [the Rose-Dooley agreement].

At the time Vulcan increased the prices of stone to amounts in excess of those specified in [the Rose-Dooley contract], plaintiff was engaged in his ready-mix cement business, using large quantities of stone, and had no other practical source of supply. Advising Vulcan that he intended to sue for breach of contract, he continued to purchase stone from Vulcan under protest.…

The total of these amounts over and above the prices specified in [the Rose-Dooley contract] is $25,231.57, [about $260,000 in 2024 dollars] and plaintiff seeks to recover said amount in this action.

The [Rose-Dooley] agreement was an executory bilateral contract under which plaintiff’s promise not to compete for ten years gained him a ten-year option to buy stone at specified prices. In most states, the assignee of an executory bilateral contract is not liable to anyone for the nonperformance of the assignor’s duties thereunder unless he expressly promises his assignor or the other contracting party to perform, or ‘assume,’ such duties.…These states refuse to imply a promise to perform the duties, but if the assignee expressly promises his assignor to perform, he is liable to the other contracting party on a third-party beneficiary theory. And, if the assignee makes such a promise directly to the other contracting party upon a consideration, of course he is liable to him thereon. [Citation]

A minority of states holds that the assignee of an executory bilateral contract under a general assignment becomes not only assignee of the rights of the assignor but also delegatee of his duties; and that, absent a showing of contrary intent, the assignee impliedly promises the assignor that he will perform the duties so delegated. This rule is expressed in Restatement, Contracts, s 164 (1932) as follows:

(1) Where a party under a bilateral contract which is at the time wholly or partially executory on both sides purports to assign the whole contract, his action is interpreted, in the absence of circumstances showing a contrary intention, as an assignment of the assignor’s rights under the contract and a delegation of the performance of the assignor’s duties.

(2) Acceptance by the assignee of such an assignment is interpreted, in the absence of circumstances showing a contrary intention, as both an assent to become an assignee of the assignor’s rights and as a promise to the assignor to assume the performance of the assignor’s duties.’ (emphasis added)

We…adopt the Restatement rule and expressly hold that the assignee under a general assignment of an executory bilateral contract, in the absence of circumstances showing a contrary intention, becomes the delegatee of his assignor’s duties and impliedly promises his assignor that he will perform such duties.

The rule we adopt and reaffirm here is regarded as the more reasonable view by legal scholars and textwriters. Professor Grismore says:

It is submitted that the acceptance of an assignment in this form does presumptively import a tacit promise on the part of the assignee to assume the burdens of the contract, and that this presumption should prevail in the absence of the clear showing of a contrary intention. The presumption seems reasonable in view of the evident expectation of the parties. The assignment on its face indicates an intent to do more than simply to transfer the benefits assured by the contract. It purports to transfer the contract as a whole, and since the contract is made up of both benefits and burdens both must be intended to be included.…Grismore, Is the Assignee of a Contract Liable for the Nonperformance of Delegated Duties? 18 Mich.L.Rev. 284 (1920).

In addition, with respect to transactions governed by the Uniform Commercial Code, an assignment of a contract in general terms is a delegation of performance of the duties of the assignor, and its acceptance by the assignee constitutes a promise by him to perform those duties. Our holding in this case maintains a desirable uniformity in the field of contract liability.

We further hold that the other party to the original contract may sue the assignee as a third-party beneficiary of his promise of performance which he impliedly makes to his assignor, under the rule above laid down, by accepting the general assignment.  Younce v. Lumber Co. , [Citation] (1908), holds that where the assignee makes an express promise of performance to his assignor, the other contracting party may sue him for breach thereof. We see no reason why the same result should not obtain where the assignee breaches his promise of performance implied under the rule of Restatement s 164. ‘That the assignee is liable at the suit of the third party where he expressly assumes and promises to perform delegated duties has already been decided in a few cases (citing Younce). If an express promise will support such an action it is difficult to see why a tacit promise should not have the same effect.’ Grismore, supra. Parenthetically, we note that such is the rule under the Uniform Commercial Code, [2-210].

We now apply the foregoing principles to the case at hand. The contract of 23 April 1960, between defendant and J. E. Dooley and Son, Inc., under which, as stipulated by the parties, ‘the defendant purchased the assets and obligations of J. E. Dooley and Son, Inc.,’ was a general assignment of all the assets and obligations of J. E. Dooley and Son, Inc., including those under [the Rose-Dooley contract]. When defendant accepted such assignment it thereby became delegatee of its assignor’s duties under it and impliedly promised to perform such duties.

When defendant later failed to perform such duties by refusing to continue sales of stone to plaintiff at the prices specified in [the Rose-Dooley contract], it breached its implied promise of performance and plaintiff was entitled to bring suit thereon as a third-party beneficiary.

The decision…is reversed with directions that the case be certified to the Superior Court of Forsyth County for reinstatement of the judgment of the trial court in accordance with this opinion.

  • Why did Rose need the crushed rock from the quarry he originally leased to Dooley?
  • What argument did Vulcan make as to why it should not be liable to sell crushed rock to Rose at the price set out in the Rose-Dooley contract?
  • What rule did the court here announce in deciding that Vulcan was required to sell rock at the price set out in the Rose-Dooley contract? That is, what is the controlling rule of law in this case?

Future Contracts

The law distinguishes between assigning future rights under an existing contract and assigning rights that will arise from a future contract. Rights contingent on a future event can be assigned in exactly the same manner as existing rights, as long as the contingent rights are already incorporated in a contract. Ben has a long-standing deal with his neighbor, Mrs. Robinson, to keep the latter’s walk clear of snow at twenty dollars a snowfall. Ben is saving his money for a new printer, but when he is eighty dollars shy of the purchase price, he becomes impatient and cajoles a friend into loaning him the balance. In return, Ben assigns his friend the earnings from the next four snowfalls. The assignment is effective. However, a right that will arise from a future contract cannot be the subject of a present assignment.

Partial Assignments

An assignor may assign part of a contractual right, but only if the obligor can perform that part of his contractual obligation separately from the remainder of his obligation. Assignment of part of a payment due is always enforceable. However, if the obligor objects, neither the assignor nor the assignee may sue him unless both are party to the suit. Mrs. Robinson owes Ben one hundred dollars. Ben assigns fifty dollars of that sum to his friend. Mrs. Robinson is perplexed by this assignment and refuses to pay until the situation is explained to her satisfaction. The friend brings suit against Mrs. Robinson. The court cannot hear the case unless Ben is also a party to the suit. This ensures all parties to the dispute are present at once and avoids multiple lawsuits.

Successive Assignments

It may happen that an assignor assigns the same interest twice. With certain exceptions, the first assignee takes precedence over any subsequent assignee. One obvious exception is when the first assignment is ineffective or revocable. A subsequent assignment has the effect of revoking a prior assignment that is ineffective or revocable. Another exception: if in good faith the subsequent assignee gives consideration for the assignment and has no knowledge of the prior assignment, he takes precedence whenever he obtains payment from, performance from, or a judgment against the obligor, or whenever he receives some tangible evidence from the assignor that the right has been assigned (e.g., a bank deposit book or an insurance policy).

Some states follow the different English rule: the first assignee to give notice to the obligor has priority, regardless of the order in which the assignments were made. Furthermore, if the assignment falls within the filing requirements of UCC Article 9 the first assignee to file will prevail.

Assignor’s Warranties

An assignor has legal responsibilities in making assignments. Unless the contract explicitly states to the contrary, a person who assigns a right for value makes certain assignor’s  warranties   to the assignee: that he will not upset the assignment, that he has the right to make it, and that there are no defenses that will defeat it. However, the assignor does not guarantee payment; assignment does not by itself amount to a warranty that the obligor is solvent or will perform as agreed in the original contract. Mrs. Robinson owes Ben fifty dollars. Ben assigns this sum to his friend. Before the friend collects, Ben releases Mrs. Robinson from her obligation. The friend may sue Ben for the fifty dollars. Or again, if Ben represents to his friend that Mrs. Robinson owes him (Ben) fifty dollars and assigns his friend that amount, but in fact Mrs. Robinson does not owe Ben that much, then Ben has breached his assignor’s warranty. The assignor’s warranties may be express or implied.

14.1 Assignment of Contract Rights

Learning objectives.

  • Understand what an assignment is and how it is made.
  • Recognize the effect of the assignment.
  • Know when assignments are not allowed.
  • Understand the concept of assignor’s warranties.

The Concept of a Contract Assignment

Contracts create rights and duties. By an assignment The passing or delivering by one person to another of the right to a contract benefit. , an obligee One to whom an obligation is owed. (one who has the right to receive a contract benefit) transfers a right to receive a contract benefit owed by the obligor One who owes an obligation. (the one who has a duty to perform) to a third person ( assignee One to whom the right to receive benefit of a contract is passed or delivered. ); the obligee then becomes an assignor One who agrees to allow another to receive the benefit of a contract. (one who makes an assignment).

The Restatement (Second) of Contracts defines an assignment of a right as “a manifestation of the assignor’s intention to transfer it by virtue of which the assignor’s right to performance by the obligor is extinguished in whole or in part and the assignee acquires the right to such performance.” Restatement (Second) of Contracts, Section 317(1). The one who makes the assignment is both an obligee and a transferor. The assignee acquires the right to receive the contractual obligations of the promisor, who is referred to as the obligor (see Figure 14.1 "Assignment of Rights" ). The assignor may assign any right unless (1) doing so would materially change the obligation of the obligor, materially burden him, increase his risk, or otherwise diminish the value to him of the original contract; (2) statute or public policy forbids the assignment; or (3) the contract itself precludes assignment. The common law of contracts and Articles 2 and 9 of the Uniform Commercial Code (UCC) govern assignments. Assignments are an important part of business financing, such as factoring. A factor A person who pays money to receive another’s executory contractual benefits. is one who purchases the right to receive income from another.

Figure 14.1 Assignment of Rights

contract partial assignment

Method of Assignment

Manifesting assent.

To effect an assignment, the assignor must make known his intention to transfer the rights to the third person. The assignor’s intention must be that the assignment is effective without need of any further action or any further manifestation of intention to make the assignment. In other words, the assignor must intend and understand himself to be making the assignment then and there; he is not promising to make the assignment sometime in the future.

Under the UCC, any assignments of rights in excess of $5,000 must be in writing, but otherwise, assignments can be oral and consideration is not required: the assignor could assign the right to the assignee for nothing (not likely in commercial transactions, of course). Mrs. Franklin has the right to receive $750 a month from the sale of a house she formerly owned; she assigns the right to receive the money to her son Jason, as a gift. The assignment is good, though such a gratuitous assignment is usually revocable, which is not the case where consideration has been paid for an assignment.

Acceptance and Revocation

For the assignment to become effective, the assignee must manifest his acceptance under most circumstances. This is done automatically when, as is usually the case, the assignee has given consideration for the assignment (i.e., there is a contract between the assignor and the assignee in which the assignment is the assignor’s consideration), and then the assignment is not revocable without the assignee’s consent. Problems of acceptance normally arise only when the assignor intends the assignment as a gift. Then, for the assignment to be irrevocable, either the assignee must manifest his acceptance or the assignor must notify the assignee in writing of the assignment.

Notice to the obligor is not required, but an obligor who renders performance to the assignor without notice of the assignment (that performance of the contract is to be rendered now to the assignee) is discharged. Obviously, the assignor cannot then keep the consideration he has received; he owes it to the assignee. But if notice is given to the obligor and she performs to the assignor anyway, the assignee can recover from either the obligor or the assignee, so the obligor could have to perform twice, as in Exercise 2 at the chapter’s end, Aldana v. Colonial Palms Plaza . Of course, an obligor who receives notice of the assignment from the assignee will want to be sure the assignment has really occurred. After all, anybody could waltz up to the obligor and say, “I’m the assignee of your contract with the bank. From now on, pay me the $500 a month, not the bank.” The obligor is entitled to verification of the assignment.

Effect of Assignment

General rule.

An assignment of rights effectively makes the assignee stand in the shoes of An assignee takes no greater rights than his assignor had. the assignor. He gains all the rights against the obligor that the assignor had, but no more. An obligor who could avoid the assignor’s attempt to enforce the rights could avoid a similar attempt by the assignee. Likewise, under UCC Section 9-318(1), the assignee of an account is subject to all terms of the contract between the debtor and the creditor-assignor. Suppose Dealer sells a car to Buyer on a contract where Buyer is to pay $300 per month and the car is warranted for 50,000 miles. If the car goes on the fritz before then and Dealer won’t fix it, Buyer could fix it for, say, $250 and deduct that $250 from the amount owed Dealer on the next installment (called a setoff). Now, if Dealer assigns the contract to Assignee, Assignee stands in Dealer’s shoes, and Buyer could likewise deduct the $250 from payment to Assignee.

The “shoe rule” does not apply to two types of assignments. First, it is inapplicable to the sale of a negotiable instrument to a holder in due course (covered in detail Chapter 23 "Negotiation of Commercial Paper" ). Second, the rule may be waived: under the UCC and at common law, the obligor may agree in the original contract not to raise defenses against the assignee that could have been raised against the assignor. Uniform Commercial Code, Section 9-206. While a waiver of defenses Surrender by a party of legal rights otherwise available to him or her. makes the assignment more marketable from the assignee’s point of view, it is a situation fraught with peril to an obligor, who may sign a contract without understanding the full import of the waiver. Under the waiver rule, for example, a farmer who buys a tractor on credit and discovers later that it does not work would still be required to pay a credit company that purchased the contract; his defense that the merchandise was shoddy would be unavailing (he would, as used to be said, be “having to pay on a dead horse”).

For that reason, there are various rules that limit both the holder in due course and the waiver rule. Certain defenses, the so-called real defenses (infancy, duress, and fraud in the execution, among others), may always be asserted. Also, the waiver clause in the contract must have been presented in good faith, and if the assignee has actual notice of a defense that the buyer or lessee could raise, then the waiver is ineffective. Moreover, in consumer transactions, the UCC’s rule is subject to state laws that protect consumers (people buying things used primarily for personal, family, or household purposes), and many states, by statute or court decision, have made waivers of defenses ineffective in such consumer transactions A contract for household or domestic purposes, not commercial purposes. . Federal Trade Commission regulations also affect the ability of many sellers to pass on rights to assignees free of defenses that buyers could raise against them. Because of these various limitations on the holder in due course and on waivers, the “shoe rule” will not govern in consumer transactions and, if there are real defenses or the assignee does not act in good faith, in business transactions as well.

When Assignments Are Not Allowed

The general rule—as previously noted—is that most contract rights are assignable. But there are exceptions. Five of them are noted here.

Material Change in Duties of the Obligor

When an assignment has the effect of materially changing the duties that the obligor must perform, it is ineffective. Changing the party to whom the obligor must make a payment is not a material change of duty that will defeat an assignment, since that, of course, is the purpose behind most assignments. Nor will a minor change in the duties the obligor must perform defeat the assignment.

Several residents in the town of Centerville sign up on an annual basis with the Centerville Times to receive their morning paper. A customer who is moving out of town may assign his right to receive the paper to someone else within the delivery route. As long as the assignee pays for the paper, the assignment is effective; the only relationship the obligor has to the assignee is a routine delivery in exchange for payment. Obligors can consent in the original contract, however, to a subsequent assignment of duties. Here is a clause from the World Team Tennis League contract: “It is mutually agreed that the Club shall have the right to sell, assign, trade and transfer this contract to another Club in the League, and the Player agrees to accept and be bound by such sale, exchange, assignment or transfer and to faithfully perform and carry out his or her obligations under this contract as if it had been entered into by the Player and such other Club.” Consent is not necessary when the contract does not involve a personal relationship.

Assignment of Personal Rights

When it matters to the obligor who receives the benefit of his duty to perform under the contract, then the receipt of the benefit is a personal right The right or duty of a particular person to perform or receive contract duties or benefits; cannot be assigned. that cannot be assigned. For example, a student seeking to earn pocket money during the school year signs up to do research work for a professor she admires and with whom she is friendly. The professor assigns the contract to one of his colleagues with whom the student does not get along. The assignment is ineffective because it matters to the student (the obligor) who the person of the assignee is. An insurance company provides auto insurance covering Mohammed Kareem, a sixty-five-year-old man who drives very carefully. Kareem cannot assign the contract to his seventeen-year-old grandson because it matters to the insurance company who the person of its insured is. Tenants usually cannot assign (sublet) their tenancies without the landlord’s permission because it matters to the landlord who the person of their tenant is. Section 14.4.1 "Nonassignable Rights" , Nassau Hotel Co. v. Barnett & Barse Corp. , is an example of the nonassignability of a personal right.

Assignment Forbidden by Statute or Public Policy

Various federal and state laws prohibit or regulate some contract assignment. The assignment of future wages is regulated by state and federal law to protect people from improvidently denying themselves future income because of immediate present financial difficulties. And even in the absence of statute, public policy might prohibit some assignments.

Contracts That Prohibit Assignment

Assignability of contract rights is useful, and prohibitions against it are not generally favored. Many contracts contain general language that prohibits assignment of rights or of “the contract.” Both the Restatement and UCC Section 2-210(3) declare that in the absence of any contrary circumstances, a provision in the agreement that prohibits assigning “the contract” bars “only the delegation to the assignee of the assignor’s performance.” Restatement (Second) of Contracts, Section 322. In other words, unless the contract specifically prohibits assignment of any of its terms, a party is free to assign anything except his or her own duties.

Even if a contractual provision explicitly prohibits it, a right to damages for breach of the whole contract is assignable under UCC Section 2-210(2) in contracts for goods. Likewise, UCC Section 9-318(4) invalidates any contract provision that prohibits assigning sums already due or to become due. Indeed, in some states, at common law, a clause specifically prohibiting assignment will fail. For example, the buyer and the seller agree to the sale of land and to a provision barring assignment of the rights under the contract. The buyer pays the full price, but the seller refuses to convey. The buyer then assigns to her friend the right to obtain title to the land from the seller. The latter’s objection that the contract precludes such an assignment will fall on deaf ears in some states; the assignment is effective, and the friend may sue for the title.

Future Contracts

The law distinguishes between assigning future rights under an existing contract and assigning rights that will arise from a future contract. Rights contingent on a future event can be assigned in exactly the same manner as existing rights, as long as the contingent rights are already incorporated in a contract. Ben has a long-standing deal with his neighbor, Mrs. Robinson, to keep the latter’s walk clear of snow at twenty dollars a snowfall. Ben is saving his money for a new printer, but when he is eighty dollars shy of the purchase price, he becomes impatient and cajoles a friend into loaning him the balance. In return, Ben assigns his friend the earnings from the next four snowfalls. The assignment is effective. However, a right that will arise from a future contract cannot be the subject of a present assignment.

Partial Assignments

An assignor may assign part of a contractual right, but only if the obligor can perform that part of his contractual obligation separately from the remainder of his obligation. Assignment of part of a payment due is always enforceable. However, if the obligor objects, neither the assignor nor the assignee may sue him unless both are party to the suit. Mrs. Robinson owes Ben one hundred dollars. Ben assigns fifty dollars of that sum to his friend. Mrs. Robinson is perplexed by this assignment and refuses to pay until the situation is explained to her satisfaction. The friend brings suit against Mrs. Robinson. The court cannot hear the case unless Ben is also a party to the suit. This ensures all parties to the dispute are present at once and avoids multiple lawsuits.

Successive Assignments

It may happen that an assignor assigns the same interest twice (see Figure 14.2 "Successive Assignments" ). With certain exceptions, the first assignee takes precedence over any subsequent assignee. One obvious exception is when the first assignment is ineffective or revocable. A subsequent assignment has the effect of revoking a prior assignment that is ineffective or revocable. Another exception: if in good faith the subsequent assignee gives consideration for the assignment and has no knowledge of the prior assignment, he takes precedence whenever he obtains payment from, performance from, or a judgment against the obligor, or whenever he receives some tangible evidence from the assignor that the right has been assigned (e.g., a bank deposit book or an insurance policy).

Some states follow the different English rule: the first assignee to give notice to the obligor has priority, regardless of the order in which the assignments were made. Furthermore, if the assignment falls within the filing requirements of UCC Article 9 (see Chapter 28 "Secured Transactions and Suretyship" ), the first assignee to file will prevail.

Figure 14.2 Successive Assignments

Assignor’s Warranties

An assignor has legal responsibilities in making assignments. He cannot blithely assign the same interests pell-mell and escape liability. Unless the contract explicitly states to the contrary, a person who assigns a right for value makes certain assignor’s warranties Promises, express or implied, made by an assignor to the assignee about the merits of the assignment. to the assignee: that he will not upset the assignment, that he has the right to make it, and that there are no defenses that will defeat it. However, the assignor does not guarantee payment; assignment does not by itself amount to a warranty that the obligor is solvent or will perform as agreed in the original contract. Mrs. Robinson owes Ben fifty dollars. Ben assigns this sum to his friend. Before the friend collects, Ben releases Mrs. Robinson from her obligation. The friend may sue Ben for the fifty dollars. Or again, if Ben represents to his friend that Mrs. Robinson owes him (Ben) fifty dollars and assigns his friend that amount, but in fact Mrs. Robinson does not owe Ben that much, then Ben has breached his assignor’s warranty. The assignor’s warranties may be express or implied.

Key Takeaway

Generally, it is OK for an obligee to assign the right to receive contractual performance from the obligor to a third party. The effect of the assignment is to make the assignee stand in the shoes of the assignor, taking all the latter’s rights and all the defenses against nonperformance that the obligor might raise against the assignor. But the obligor may agree in advance to waive defenses against the assignee, unless such waiver is prohibited by law.

There are some exceptions to the rule that contract rights are assignable. Some, such as personal rights, are not circumstances where the obligor’s duties would materially change, cases where assignability is forbidden by statute or public policy, or, with some limits, cases where the contract itself prohibits assignment. Partial assignments and successive assignments can happen, and rules govern the resolution of problems arising from them.

When the assignor makes the assignment, that person makes certain warranties, express or implied, to the assignee, basically to the effect that the assignment is good and the assignor knows of no reason why the assignee will not get performance from the obligor.

  • If Able makes a valid assignment to Baker of his contract to receive monthly rental payments from Tenant, how is Baker’s right different from what Able’s was?
  • Able made a valid assignment to Baker of his contract to receive monthly purchase payments from Carr, who bought an automobile from Able. The car had a 180-day warranty, but the car malfunctioned within that time. Able had quit the auto business entirely. May Carr withhold payments from Baker to offset the cost of needed repairs?
  • Assume in the case in Exercise 2 that Baker knew Able was selling defective cars just before his (Able’s) withdrawal from the auto business. How, if at all, does that change Baker’s rights?
  • Why are leases generally not assignable? Why are insurance contracts not assignable?

CHAPTER 9 - SECTION 1

Chapter 9: assignment of rights,transfer of obligations, assignment of contracts - section 1: assignment of rights, article 9.1.1 (definitions).

“Assignment of a right” means the transfer by agreement from one person (the “assignor”) to another person (the “assignee”), including transfer by way of security, of the assignor’s right to payment of a monetary sum or other performance from a third person (“the obligor”).

In many circumstances an obligee entitled to the payment of a monetary sum or to another performance from an obligor may find it useful to assign its right to another person. For instance, an assignment to a bank is a common way to finance the credit granted to a customer. The Articles of the present Section cover the assignment of rights as defined in this Article.

1. Transfer by agreement

Only transfers by agreement are concerned, as opposed to situations in which the applicable law may provide for legal transfers of certain rights (such as, in certain jurisdictions, the transfer of a seller’s rights against an insurer to the purchaser of an insured building, or the automatic transfer of rights in the case of the merger of companies (see Article 9.1.2(b)).

The definition equally does not cover unilateral transfers, which in certain jurisdictions may take place without the assignee’s participation.

2. Right to payment of a monetary sum or to other performance

On the other hand, the definition is not restricted to the assignment of rights to the payment of a monetary sum. It also covers rights to other kinds of performance, such as the rendering of a service. Nor are the assignable rights limited to rights of a contractual nature. Claims deriving from non-contractual claims or based on a judgment, for instance, can be governed by the present Section, subject to Article 1.4. Future rights may also be transferred under the conditions of Article 9.1.5.

3. Notion of “transfer”

The “transfer” of the right means that it leaves the assignor’s assets to become part of those of the assignee. The definition also covers transfers for security purposes.

4. Third party rights

Transfers from the assets of the assignor to those of the assignee remain subject to third party rights. Different third persons can be affected by the assignment of a right between an assignor and an assignee, such as, first and foremost, the obligor, but also the assignor’s creditors and successive assignees. Third party rights are covered in part by other provisions of this Section (see Articles 9.1.10 and 9.1.11 concerning the obligor and successive assignees). They may in some instances be governed by mandatory rules of the otherwise applicable law (e.g. the law of bankruptcy).

ARTICLE 9.1.2 (EXCLUSIONS)

This Section does not apply to transfers made under the special rules governing the transfers: 

(a) of instruments such as negotiable instruments, documents of title or financial instruments, or 

(b) of rights in the course of transferring a business.

Some types of assignment of rights are normally subject to very specific rules under the applicable law, and are therefore not governed by this Section.

1. Transfer of instruments governed by special rules

The transfer of certain types of instrument governed by special rules are outside the scope of this Section. This applies for instance to negotiable instruments, such as bills of exchange, that are usually transferred by endorsement or delivery of the document, and which are subject to further distinct rules, e.g. concerning defences that would have been available to the transferor. This exclusion also applies to documents of title, such as bills of lading or warehouse receipts, and financial instruments such as stocks and bonds. The transfer of such instruments are all normally subject to specific rules.

This does not exclude the possibility that such rights, in certain jurisdictions, could also be transferred by a normal assignment, which would then be subject to this Section.

2. Transfer of a business

Another exclusion is assignment made in the course of transferring a business under special rules governing such transfers, as may happen in the case of the merger of companies. The applicable law often provides for mechanisms that cause all rights and obligations, under certain conditions, to be transferred in their entirety by operation of law.

Article 9.1.2(b) does not prevent this Section from applying when certain rights pertaining to the transferred business are assigned individually. On the contrary, the mere transfer of shares in a company may fall under Article 9.1.2(a) and therefore not be covered by this Section.

Illustrations

1. Company A is transferred to company B. If the otherwise applicable law provides that all rights pertaining to the former company are automatically transferred to the latter, the Principles do not apply.

2. The initial facts are the same as in Illustration 1, but B is not interested in taking over a specific claim against customer X, and prefers that right to be assigned to company C. This particular transfer is subject to the Principles.

ARTICLE 9.1.3 (ASSIGNABILITY OF NON-MONETARY RIGHTS)

A right to non-monetary performance may be assigned only if the assignment does not render the obligation significantly more burdensome.

The assignment of a right does not in principle affect the obligor’s rights and obligations. However, to a certain extent the fact that performance is now due to another obligee can modify the conditions under which the obligation is to be performed. The place of performance may be different. The change of obligee may in itself render the obligation more burdensome.

Article 9.1.8 entitles the obligor to be compensated by the assignor or the assignee for any additional costs caused by the assignment. That provision should be sufficient to take care of the problem in the case of the assignment of monetary obligations. However, when the assigned right concerns a non-monetary performance, the remedy may not always be sufficient. This Article excludes the possibility of assigning such rights when the transfer would render the obligation significantly more burdensome for the obligor.

1. Company X has undertaken to provide the security service aimed at preventing theft in warehouses used by company A for the storage of wood. The premises are sold to company B, which intends to apply them to the same use. Nothing in this provision prevents A from assigning to B its right to the security services provided by X.

2. The initial facts are the same as in Illustration 1, but B intends to use the warehouses for the storage of electronic equipment. A’s right to the security services provided by X may not be assigned to B: such services would become significantly more burdensome since the security risks are obviously much higher with electronic equipment than with the storage of wood.

ARTICLE 9.1.4 (PARTIAL ASSIGNMENT)

(1) A right to the payment of a monetary sum may be assigned partially. 

(2) A right to other performance may be assigned partially only if it is divisible, and the assignment does not render the obligation significantly more burdensome.

1. Economic interest

The partial assignment of a right may serve different economic purposes. A contractor may for instance want to assign part of its right to payment from a customer to a financing institution and keep the rest for itself. Or it may want to assign the other part to a supplier of raw materials.

Permitting partial assignment may however affect the principle that the assignment should not worsen the obligor’s situation. If the right is split, the obligor will have to perform in several parts, which could entail extra costs.

2. Monetary and non-monetary rights

The obligor’s burden of having to make two or several monetary payments instead of one is not in itself deemed to be excessive, and partial assignments of monetary rights are therefore permitted in principle (paragraph (1)).

Another rule prevails for the assignment of non-monetary rights, where the validity of the partial assignment is made dependent on two cumulative conditions: the divisibility of the performance due and the degree of additional burden the partial assignment may place on the obligor. Article 9.1.3 already excludes the possibility to assign non-monetary rights in their entirety if the assignment would render the obligation significantly more burdensome. Paragraph (2) applies the same rule to the partial assignment of such rights.

In any event, additional costs borne by the obligor as a result of having to perform in several parts must be compensated under Article 9.1.8.

1. Buyer X is due to pay a price of USD 1,000,000 to seller A on 31 October. A urgently needs USD 600,000 and assigns a corresponding part of its right to bank B. Notice of the partial assignment is given to X. On 31 October, both A and B claim payment of their respective parts. X must pay A USD 400,000 and B USD 600,000.

2. Metal company X is to deliver 1,000 tons of steel to carmaker A on 31 October. Due to a decrease in sales, A estimates that it will not need that much steel at that time, and assigns the right to delivery of up to 300 tons to carmaker B. Notice of the partial assignment is given to X. On 31 October both A and B claim delivery of their respective quantities. X must deliver 700 tons to A and 300 tons to B.

3. Tax consultant X has promised to spend 30 days in examining the accounts of company A in order to determine the proper policy to be followed in the light of new tax regulations. A subsequently regrets this arrangement, in consideration of the level of the fees to be paid. It proposes to assign 15 of the days to company B. X can argue against such a partial assignment on the grounds that performance of tasks of that nature is not divisible. It can also argue that the accounts of B are of a significantly more complex nature than those of A.

ARTICLE 9.1.5 (FUTURE RIGHTS)

A future right is deemed to be transferred at the time of the agreement, provided the right, when it comes into existence, can be identified as the right to which the assignment relates.

For the purposes of this Section, a future right is a right that will or might come into existence in the future (as opposed to a present right to a performance due in the future). Examples of future rights are rights that a bank may have against a customer who might be granted a credit line in the future, or that a company may have against another company on the basis of a contract which might be concluded in the future. The assignment of such future rights can be highly significant economically.

2. Determinability

According to this Article a future right can be assigned on condition that it can be determined as the right to which the assignment relates when it comes into existence. The reason for this is the need to avoid the difficulties that might be caused by a transfer of future rights that are described in vague and too broad general terms.

3. Retroactive effect

This Article also provides that the assignment of future rights is effective with retroactivity between the assignor and the assignee. When the right comes into existence, the transfer is considered to have taken place at the time of the assignment agreement.

As regards third parties, it will be recalled that their rights may in some instances be governed by mandatory rules of the otherwise applicable law (e.g. the law of bankruptcy). However, third party rights are partly covered by other provisions of this Section, including the consequences of notices specified in Articles 9.1.10 and 9.1.11.

Illustration

In order to finance new investments, company A assigns the royalties to be earned from future licences of a certain technology to lending institution B. Six months later, A licenses that technology to company X. The royalties due are considered to have been assigned to B from the date of the assignment agreement, provided the royalties can be related to this agreement.

ARTICLE 9.1.6 (RIGHTS ASSIGNED WITHOUT INDIVIDUAL SPECIFICATION)

A number of rights may be assigned without individual specification, provided such rights can be identified as rights to which the assignment relates at the time of the assignment or when they come into existence.

Rights are often assigned as a bundle or in bulk. A company may for instance assign all its receivables to a factoring company. In practice it would be excessively burdensome to require individual specification of each assigned right, but the global identification of the rights assigned as a bundle must be such as to permit the recognition of each right concerned as part of the assignment.

In the case of existing rights, such recognition must be possible at the time of the assignment. If future rights are included in the bundle, in accordance with Article 9.1.5 identification must be possible when the rights come into existence.

Retailer A assigns all its receivables to factor B. There are thousands of existing and/or future rights. The assignment does not require the specification of each single claim. Later, B gives notice of the assignment to the obligor of a specific receivable. B must be able to demonstrate the inclusion of that receivable in the bundle either at the time of the assignment, or, in the case of a right which did not exist yet at that time, when the right came into existence.

ARTICLE 9.1.7 (AGREEMENT BETWEEN ASSIGNOR AND ASSIGNEE SUFFICIENT)

(1) A right is assigned by mere agreement between the assignor and the assignee, without notice to the obligor. 

(2) The consent of the obligor is not required unless the obligation in the circumstances is of an essentially personal character.

In the definition of Article 9.1.1 the assignment of a right is described as a “transfer by agreement”. Articles 9.1.7 to 9.1.15 govern the respective legal positions of assignor, assignee and obligor.

1. Mere agreement between assignor and assignee

According to paragraph (1) of this Article, the assignment of a right is effective, i.e. the right is transferred from the assignor’s assets to the assignee’s assets, by mere agreement between these two parties. The provision is an application to the assignment of a right of the general principle laid down in Article 1.2 according to which nothing in the Principles requires a contract to be concluded in a particular form. Yet it does not affect the possible application of mandatory rules of the otherwise applicable law according to Article 1.4: thus, for instance, an assignment for security purposes may be subject to special requirements as to form.

As already stated in Comment 4 on Article 9.1.1, the rule laid down in paragraph (1) remains subject to third party rights, which are partly covered by other provisions of this Section (see Articles 9.1.10 and 9.1.11 concerning the obligor and successive assignees), and may in some instances be governed by mandatory rules of the otherwise applicable law (e.g. the law of bankruptcy) according to Article 1.4. However, it should be stressed that notice to the obligor as provided for by Article 9.1.10 is not a condition for the effectiveness of the transfer of the right(s) between the assignor and the assignee.

2. Consent of the obligor in principle not required

Paragraph (2) states explicitly what is already implied in paragraph (1), i.e. that the obligor’s consent is not required for the assignment to be effective between the assignor and the assignee.

3. Exception: obligation of an essentially personal character

An exception is made for the case in which the right to be assigned relates to an obligation of an essentially personal character, i.e. a right that has been granted by the obligor specifically to the person of the obligee. This characteristic prevents the right from being assigned without the consent of the obligor, since it would be inappropriate to oblige the obligor to perform in favour of another person.

1. Company X promises to sponsor activities organised by organisation A, engaged in the defence of human rights. A wishes to assign the right to organisation B, active in the protection of the environment. The assignment can only take place with X’s agreement.

2. A famous soprano has made a contract with agent A to sing in concerts organised by A. A sells its claims against the soprano to agent B. This transfer will require the soprano’s consent, if the circumstances reveal that she was willing to sing only for A.

4. Effect of other provisions

The possibility to assign a right without the obligor’s consent may be affected by the presence of a non-assignment clause in the contract between the assignor and the obligor (see Article 9.1.9), although such a clause does not in itself necessarily imply the essentially personal character of the obligation.

This Article does not address the issue of the necessity to give notice of the assignment to the obligor in order to avoid that the obligor pay the assignor after the assignment has taken place. On these issues, see Articles 9.1.10 and 9.1.11.

ARTICLE 9.1.8 (OBLIGOR’S ADDITIONAL COSTS)

The obligor has a right to be compensated by the assignor or the assignee for any additional costs caused by the assignment.

1. Compensation for additional costs

The assignment of a right does not necessarily affect the obligor’s rights and obligations. However, should the obligor bear additional costs due to the fact that performance has to be rendered to the assignee instead of the original obligee, this Article entitles the obligor to require due compensation.

1. Company X is obliged to reimburse a loan of EUR 1,000,000 to company A. Both companies are located in country M. A assigns its right to company B, located in country N. X has a right to be compensated for the additional costs involved in what has now become an international transfer.

The rule laid down in this Article is in conformity with Article 6.1.6, which provides a similar solution if a party to the contract changes its place of business after the conclusion of the contract.

2. Compensation by the assignor or the assignee

The obligor may claim compensation for additional costs either from the assignor or from the assignee. In the case of a monetary obligation, the obligor will often be in a position to set off its right to compensation against the obligation it owes to the assignee.

3. Partial assignment

Additional costs may arise in particular in the case of partial assignment (see Article 9.1.4). This Article applies accordingly.

2. In Illustration 2 to Article 9.1.4, A has assigned to B part of its right to receive a delivery of steel from X. Instead of having to deliver 1,000 tons to A, X became obliged to deliver 700 tons to A and 300 tons to B. X is entitled to be compensated for the additional costs resulting from having to deliver in two parts.

4. Obligation becoming significantly more burdensome

In two cases compensation for additional costs is not considered to be a sufficient remedy. Firstly, under Article 9.1.3 the assignment of a right to a non-monetary performance is not allowed when it would render the obligation significantly more burdensome. Secondly, under Article 9.1.4 the partial assignment of a right to a non-monetary performance is also not allowed in similar circumstances.

ARTICLE 9.1.9 (NON-ASSIGNMENT CLAUSES)

(1) The assignment of a right to the payment of a monetary sum is effective notwithstanding an agreement between the assignor and the obligor limiting or prohibiting such an assignment. However, the assignor may be liable to the obligor for breach of contract. 

(2) The assignment of a right to other performance is ineffective if it is contrary to an agreement between the assignor and the obligor limiting or prohibiting the assignment. Nevertheless, the assignment is effective if the assignee, at the time of the assignment, neither knew nor ought to have known of the agreement. The assignor may then be liable to the obligor for breach of contract.

1. Balance of interests

According to Article 9.1.7(2) the consent of the obligor is not required for the assignment to be effective between the assignor and the assignee unless the obligation is of an essentially personal character. However, in practice it is frequent for the contract between the original obligee/assignor and the obligor to contain a clause limiting or prohibiting the assignment of the original obligee/assignor’s rights as the obligor may not wish to change obligee. Should the original obligee/assignor subsequently assign such rights in spite of the non-assignment clause, the conflicting interests of the obligor and of the assignee must be weighed. The obligor suffers a violation of its contractual rights, but the assignee must equally be protected. At a more general level, it is also important to favour the assignment of rights as an efficient means of financing.

In this respect this Article makes a distinction between the assignment of monetary rights and the assignment of rights to other performances.

2. Monetary rights

In the case of the assignment of monetary rights, paragraph (1) gives preference to the needs of credit. The assignee of a monetary right is protected against non-assignment clauses and the assignment is fully effective. However, as the assignor acts contrary to its contractual duties, it is liable in damages to the obligor for non-performance of the contract under Chapter 7, Section 4.

1. Contractor A is entitled to the payment of USD 100,000 from its customer X after a certain stage of construction work has been completed. The contract contains a clause prohibiting A from assigning the right. A nevertheless assigns the right to bank B. B can rely on the assignment despite the clause, and can claim payment when it is due. X is however entitled to sue A for acting in breach of the clause. X could for instance claim damages if it demonstrates that it has suffered some prejudice.

2. Company X is to reimburse EUR 500,000 to company A at a date when it can set off this obligation partially with a claim of EUR 200,000 it has against A. The contract between X and A contains a non-assignment clause. Disregarding that clause, A assigns its right to reimbursement to company B. X may claim damages against A for the costs it incurs in having to engage in a separate procedure to recover the sum of EUR 200,000.

3. Non-monetary rights

The assignment of rights to non-monetary performances does not have the same relationship to credit, thus justifying another solution which is to be found in paragraph (2). In order to achieve a fair balance between the conflicting interests of the three parties concerned, the rule is that non-assignment clauses are given effect vis-à-vis the assignee with the result that the assignment is ineffective. The solution is however reversed if it can be established that, at the time of the assignment, the assignee did not know and ought not to have known of the non-assignment clause. In such a case, the assignment is effective, but the assignor may be liable in damages to the obligor for non-performance of the contract under Chapter 7, Section 4.

3. Company X has agreed to communicate to company A all improvements it will develop to a technical process over a period of time. Their contract stipulates that A’s rights towards X may not be assigned. A does not need the technology for itself any longer and attempts to assign its rights to company B. Such an assignment is ineffective. X does not become B’s obligor. In such a case, B has a claim against A under Article 9.1.15(b).

ARTICLE 9.1.10 (NOTICE TO THE OBLIGOR)

(1) Until the obligor receives a notice of the assignment from either the assignor or the assignee, it is discharged by paying the assignor. 

(2) After the obligor receives such a notice, it is discharged only by paying the assignee.

1. Effect of notice on the obligor

Whereas the assignment is effective between the assignor and the assignee as a result of their agreement (see Article 9.1.7), the obligor will be discharged by paying the assignor until it receives notice of the assignment. If the obligor pays the assignor, the assignee can recover that payment from the assignor (see Article 9.1.15(f)). Only after the obligor receives a notice of assignment does the assignment become effective towards the obligor. The obligor can then be discharged only by paying the assignee.

1. Seller A assigns its right to payment from buyer X to bank B. Neither A nor B gives notice to X. When payment is due, X pays A. This payment is fully valid and X is discharged. It will be up to B to recover it from A under Article 9.1.15(f).

2. Seller A assigns to bank B its right to payment from buyer X. B immediately gives notice of the assignment to X. When payment is due, X still pays A. X is not discharged and B is entitled to oblige X to pay a second time.

Before the obligor receives a notice of the assignment, it is discharged when it pays the assignor irrespective of whether it knew, or ought to have known, of the assignment. The purpose is to place the burden of informing the obligor of the assignment on the parties to the assignment agreement, i.e. the assignor and the assignee. This solution is considered to be justified in the context of international commercial contracts. However, it does not necessarily exclude that in certain circumstances the obligor will be liable for damages if it acted in bad faith when it paid the assignor.

Parties sometimes resort to so-called “silent assignments”, where the assignor and the assignee agree not to inform the obligor of the assignment. This arrangement is valid between parties, but since the obligor receives no notice, it will be discharged by paying the assignor, as provided in Article 9.1.10(1).

2. Meaning of “notice”

“Notice” is to be understood in the broad sense of Article 1.10. Although this Article does not specify the content of the notice, the latter should indicate not only the fact of the assignment, but also the identity of the assignee, the specifications of the right transferred (subject to Article 9.1.6) and, in the case of partial assignment, the extent of the assignment.

3. Who should give notice

Article 9.1.10(1) leaves the question of who should give notice open, i.e. whether it should be the assignor or the assignee. In practice, it is probable that in most cases the assignee will take the initiative, as it has a major interest in avoiding that the obligor will perform in favour of the assignor notwithstanding the assignment. But notice given by the assignor has the same effect. When notice is given by the assignee, the obligor may request adequate proof of the assignment (see Article 9.1.12).

4. When must notice be given

This Article does not explicitly require notice to be given only after the assignment agreement has been concluded. In some cases the contract between a future assignor and the obligor will provide that the rights arising from it will be assigned to a financial institution. Whether this can be considered to be adequate notice having the consequences provided for in this Article is a matter of interpretation, and may possibly depend on the definiteness of the clause regarding the identity of the future assignee.

5. Revocation of notice

Notice given to the obligor can be revoked in certain circumstances, e.g. if the assignment agreement itself becomes invalid, or if an assignment made for security purposes is no longer necessary. This will not affect payments made before the revocation to the person who was the assignee at the time, but if the obligor pays that person after the revocation it would no longer be discharged.

ARTICLE 9.1.11 (SUCCESSIVE ASSIGNMENTS)

If the same right has been assigned by the same assignor to two or more successive assignees, the obligor is discharged by paying according to the order in which the notices were received.

1. Priority of first notice

This Article deals with the case where the same assignor assigns the same right to different assignees. Normally this should not happen, although in practice it may occur, whether the assignor does so consciously or inadvertently. Preference is then given to the assignee who was the first to give notice. The other assignees can only claim against the assignor under Article 9.1.15(c) below.

On 5 February seller A assigns its right to payment from buyer X to bank B, and then on 20 February to bank C. C notifies the assignment on 21 February, and B does so only on 25 February. X is discharged by paying C, even though the right was assigned to C after it had been assigned to B.

Unlike the solution prevailing under certain jurisdictions, this Article does not take into consideration the actual or constructive knowledge the obligor may have of the assignment(s) in the absence of notice. This approach is motivated by the wish to encourage the giving of notice, thus ensuring a degree of certainty that is especially advisable in the context of international contracts.

2. No notice given

If no notice is given by any of the successive assignees the obligor will be discharged by paying the assignor (see Article 9.1.10(1)).

3. Notice without adequate proof

Notice by an assignee without there being adequate proof that the assignment has been made, may be ineffective under Article 9.1.12.

ARTICLE 9.1.12 (ADEQUATE PROOF OF ASSIGNMENT)

(1) If notice of the assignment is given by the assignee, the obligor may request the assignee to provide within a reasonable time adequate proof that the assignment has been made. 

(2) Until adequate proof is provided, the obligor may withhold payment. 

(3) Unless adequate proof is provided, notice is not effective. 

(4) Adequate proof includes, but is not limited to, any writing emanating from the assignor and indicating that the assignment has taken place.

Since receiving the notice of assignment has the important effects provided for in Articles 9.1.10 and 9.1.11, this Article intends to protect the obligor against the risk of receiving a fraudulent notice from a fake “assignee” by requiring adequate proof that the assignment has actually been made. Until adequate proof is provided, the obligor may withhold payment to the alleged assignee. If adequate proof is provided, notice is effective from the date it was provided.

On 1 December purchaser X has to pay USD 200,000 to contractor A as an instalment of the sum due for the construction of a plant. In October A assigns the right to bank B. Either A or B may give notice of the assignment to X. If B takes the initiative and writes to X that it has become the assignee of the sum, X may require B to provide adequate proof. Without prejudice to other types of evidence, B will probably produce the assignment agreement or any other writing from A confirming that the right has been assigned. Until such adequate proof is provided, X may withhold payment.

ARTICLE 9.1.13 (DEFENCES AND RIGHTS OF SET-OFF)

(1) The obligor may assert against the assignee all defences that the obligor could assert against the assignor. 

(2) The obligor may exercise against the assignee any right of set-off available to the obligor against the assignor up to the time notice of assignment was received.

1. Assertion of defences

A right can in principle be assigned without the obligor’s consent (see Article 9.1.7(2)). This solution rests on the assumption that the assignment will not adversely affect the obligor’s legal situation.

It can happen that the obligor would have been able to withhold or refuse payment to the original obligee on the basis of a defence such as the defective performance of that obligee’s obligations vis-à-vis the obligor. To determine whether such defences can be asserted also against the assignee, the respective interests of the parties have to be weighed: the obligor’s situation should not deteriorate as a result of the assignment, while the assignee has an interest in the integrity of the right it has acquired.

According to paragraph (1) of this Article, the obligor may assert against the assignee all the defences that it would have been able to assert if the claim had been made by the assignor. In this case, however, the assignee will have a claim against the assignor under Article 9.1.15(d).

1. Software company A promises customer X to install a new accounting application before the end of the year. The main payment is to take place one month after completion. A immediately assigns the right to bank B. When the payment is due, B wants to claim it from X, but the latter explains that the new software is not working properly and that the accounting department is in chaos. X refuses to pay until this catastrophic situation has been remedied. X is justified in asserting this defence against B, which can then claim against A under Article 9.1.15(d).

The same solution applies to defences of a procedural nature.

2. Company X sells a gas turbine to contractor A, to be incorporated into a plant built for customer B. When the work has been completed, A assigns the guarantee of satisfactory performance to B. When the turbine does not work properly, B sues X before a court at its place of business. X will successfully invoke the arbitration clause included in its contract with A.

According to paragraph (2), the obligor may exercise against the assignee any right of set-off provided that the right of set-off was available to the obligor under Article 8.1 before the notice of the assignment was given.

This solution is in accord with the principle that the obligor’s situation should not deteriorate as a result of the assignment. The assignee’s interests are protected by the claim it may then have against the assignor under Article 9.1.15(e).

3. Company A assigns to company B the right to the payment of EUR 100,000 that it has against company X. X however has a claim of EUR 60,000 against A. The two claims have not yet been set off by notice given under Article 8.3 of the Principles, but the required conditions for set-off were satisfied before the assignment was notified. X may still exercise its right of set-off by giving notice to the assignee. B can then only claim EUR 40,000 from X. B can recover the difference from A which had undertaken under Article 9.1.15(e) that the obligor would not give notice of set-off as regards the assigned right.

ARTICLE 9.1.14 (RIGHTS RELATED TO THE RIGHT ASSIGNED)

The assignment of a right transfers to the assignee: 

(a) all the assignor’s rights to payment or other performance under the contract in respect of the right assigned, and 

(b) all rights securing performance of the right assigned.

1. Scope of the assignment

This provision is inspired by the same principle as Article 9.1.13. The assignment transfers the assignor’s right as it is, not only with the defences the obligor may be able to assert, but also with all the rights to payment or to other performances under the contract in respect of the right assigned, and all rights securing performance of the right assigned.

1. Bank A is entitled to receive reimbursement of a loan of EUR 1,000,000 made to customer X, bearing interest at a rate of 3%. A assigns its right to reimbursement of the principal to bank B. The assignment also operates as a transfer of the right to interest and of the underlying security.

2. The initial facts are the same as in Illustration 1, but the loan contract entitles A to claim early repayment if X fails to pay the interest due. This right is also transferred to B.

3. The initial facts are the same as in Illustration 1, but X has deposited some shares as security to the benefit of A. This benefit is transferred to B, subject to the possible application of mandatory requirements of the otherwise applicable law under Article 1.4.

2. Partial assignment

When a right is partially assigned, if the rights covered by Article 9.1.14 are divisible they will be transferred in proportion. If they are not, parties should decide whether they are transferred to the assignee or whether they will remain with the assignor.

3. Contractual deviations

The rule laid down in paragraph (1) may however be modified by an agreement between the assignor and the assignee, who may stipulate, for instance, a separate assignment of interest.

4. Assignor’s co-operation

It follows from the general duty to co-operate laid down in Article 5.1.3 that the assignor is obliged to take all the steps necessary to permit the assignee to enjoy the benefit of accessory rights and securities.

ARTICLE 9.1.15 (UNDERTAKINGS OF THE ASSIGNOR)

The assignor undertakes towards the assignee, except as otherwise disclosed to the assignee, that: 

(a) the assigned right exists at the time of the assignment, unless the right is a future right; 

(b) the assignor is entitled to assign the right; 

(c) the right has not been previously assigned to another assignee, and it is free from any right or claim from a third party; 

(d) the obligor does not have any defences; 

(e) neither the obligor nor the assignor has given notice of set-off concerning the assigned right and will not give any such notice; 

(f) the assignor will reimburse the assignee for any payment received from the obligor before notice of the assignment was given.

When assigning a right by agreement to the assignee, the assignor assumes several undertakings.

1. Existence of the right

The assigned right should exist at the time of the assignment. This would, for instance, not be the case if the payment had already been made or if the right to a payment had previously been avoided.

1. Company A assigns a bundle of rights to factor B. When required to pay by B, customer X demonstrates that the amount due had been paid to A before the assignment. B has a claim against A, since at the time of the assignment the right no longer existed.

If, as permitted by Article 9.1.5, a future right is assigned, no such undertaking exists.

2. Company A assigns to bank B the royalties from a technology licence that is to be granted in the near future to company X. The licence never materialises. B has no claim against A.

2. Assignor entitled to assign the right

The assignor is entitled to assign the right. This is, for instance, not the case if there is a legal or contractual prohibition to assign the right.

3. Company X has agreed to communicate to company A all the improvements to a technical process that it will develop over a period of time. Their contract stipulates that A’s rights towards X cannot be assigned. A no longer needs the technology itself, and attempts to assign its rights to company B. This illustration was already given above, under Article 9.1.9, to give an example of an ineffective assignment. In this case, B has a claim against A under Article 9.1.15(b). It will be recalled that the solution would be reversed, should B demonstrate that it neither knew nor ought to have known of the non-assignment clause.

3. No previous assignment, no third party rights or claims

If the assignor has already assigned a right to another assignee, it is generally not entitled to make a second assignment of that same right and this prohibition could be considered as already covered by the undertaking under sub-paragraph (b). The practical importance of this hypothesis is such that a separate and explicit provision is justified. It will however be recalled that under Article 9.1.11 the second assignee may prevail over the first one if it gives earlier notice to the obligee.

However, a previous assignment may have been made merely for security purposes. In this case, the right is still assignable, with proper disclosure to the second assignee.

4. No defence from the obligor

According to Article 9.1.13(1), the obligor may assert against the assignee all the defences that the obligor would have been able to assert against the assignor. In such a case, the assignee has a claim against the assignor on the basis of this undertaking.

4. Bank B is the assignee of contractor A’s right to payment of a certain sum from customer X. When payment is due, X refuses to pay arguing that A did not perform its obligations properly. Such defence can be successfully set up against B under Article 9.1.13(1). B would then have a claim against A.

5. No notice of set-off

The right of set-off may be exercised by the obligor against the assignee if it was available to the obligor before the notice of assign¬ment was received (see Article 9.1.13(2)). The assignor undertakes vis-à-vis the assignee that neither the assignor nor the obligor has already given notice of set-off affecting the assigned right. The assignor also undertakes that such notice will not be given in the future. If, for instance, the obligor were to give such a notice to the assignee after the assignment, as permitted by Article 9.1.13(2), the assignee would have a claim against the assignor under Article 9.1.15(e).

6. Reimbursement of payment by the obligor

Article 9.1.10(1) provides that until it receives the notice of assignment the obligor is discharged by paying the assignor. This is the correct solution to protect the obligor, but the assignor and the assignee have agreed between themselves on the transfer of the right. The assignor therefore undertakes that it will reimburse the assignee for any payment it received from the obligor before the notice of assignment was given.

5. Seller A assigns to bank B its right to payment from buyer X. Neither A nor B gives notice to X. When payment is due, X pays A. As already explained in the Comment on Article 9.1.10, this payment is fully valid and B is discharged. However, Article 9.1.15(f) enables B to recover the sum paid from A.

7. No undertaking concerning the obligor’s performance or solvency

Parties to the assignment may certainly provide for an undertaking by the assignor concerning the obligor’s present or future solvency, or, more generally, the obligor’s performance of its obligations. However, without such an agreement, there is no such undertaking under this Article.

6. Company B is the assignee of company A’s right to payment of a certain sum from customer X. When payment is due, B finds out that X has become insolvent. B has to bear the consequences. The solution would be the same if B discovered that X was already insolvent at the time of the assignment.

In case of breach of one of the assignor’s undertakings, the remedies provided for in Chapter 7 become available. The assignee may for instance claim damages from the assignor or terminate the agreement if the conditions of Article 7.3.1 et seq. are fulfilled.

8. Effect of disclosure on undertaking

Some of the assignor’s undertakings may be affected by disclosures made at the time of the transfer. The assignor may for instance advise the assignee of the existence of a claim by a third party, in which case the assignee may accept the transfer of the right at its own risk, with no undertaking on that matter on the part of the assignor.

I discovered UNIDROIT’s work through the study on Transport Terminals [when writing on OTT UN Convention (1991)]. Afterwards the Principles on International Commercial Contracts (Chapter 6, within a volume devoted to the Principles under my coordination, and Chapter 9.1, in Bonell Fs). I directed (and still I am mentoring) Master’s and PhD students’ research to deep in documents ending up in ULIS, to get a better CISG understanding on different CISG Articles (e.g., 7, 25, 78 and 79). With a group of students, we translated to Spanish the Guide to International Master Franchise Arrangements 1st. edition. Lastly, with a group of University colleagues and other bank experts we sent comments on Model Law on Factoring and on Principles on Digital Assets within the last four months or so. Apart from UNIDROIT’s works, but on international trade law area, I have had the benefit to represent Spain in UNCITRAL (1989-2014). There, I chaired the Plenary (1994) and two working groups: NIEO (1993-1994, while drafting Model Law on Procurement of Goods, Construction and Services, 1994) and the one on International Contract Practices (1995-2001) during the Convention on Assignment of Receivables on International Trade (2001) preparation. I was member of the Spain Delegation in Working Group V, dealing with Insolvency Law (2001-2014), and Working Group III (2001-2008) when drafting Rotterdam Rules. Consequently, my publications are within that ambits. In Spanish Law I wrote on Companies, Commercial Registry, Loans (with particular attention to interests’ debt in it and in other credit contracts, also on lack of timely payment). I was granted (DAAD, A. v Humboldt S. and Salvador de Madariaga) to research periods (three years in a sum) in MPI (Hamburg). I coach my University students’ teams to Willem C Vis International Commercial Arbitration Moot and to MOOTmadrid.

Assignment of Rights and Obligations Under a Contract: Everything You Need to Know

An assignment of rights and obligations under a contract occurs when a party assigns their contractual rights to a third party. 3 min read updated on October 29, 2020

An assignment of rights and obligations under a contract occurs when a party assigns their contractual rights to a third party. The benefit that the issuing party would have received from the contract is now assigned to the third party. The party appointing their rights is referred to as the assignor, while the party obtaining the rights is the assignee.

What Is an Assignment of Contract?

In an assignment contract, the assignor prefers that the assignee reverses roles and assumes the contractual rights and obligations as stated in the contract. Before this can occur, all parties to the original contract must be notified.

Contracts create duties and rights. An obligor is the party who is legally or contractually obliged to provide a benefit or payment to another, while an obligation is owed to the obligee. The obligee transfers a right to obtain a benefit owed by the obligor to a third party. At this point, the obligee becomes an assignor. An assignor is the party that actually creates an assignment. 

The party that creates an assignment is both the obligee and a transferor. The assignee receives the right to acquire the obligations of the promisor/obligor. The assignor can assign any right to the obligor unless:

  • Doing so will materially alter the obligation
  • It's materially burdening
  • It decreases the value of the original contract
  • It increases their risk
  • Public policy or a statute makes it illegal
  • The contract prevents assignment

Assignments are important in business financing, especially in factoring . A factor is someone who purchases a right to receive a benefit from someone else.

How Assignments Work

The specific language used in the contract will determine how the assignment plays out. For example, one contract may prohibit assignment, while another contract may require that all parties involved agree to it before proceeding. Remember, an assignment of contract does not necessarily alleviate an assignor from all liability. Many contracts include an assurance clause guaranteeing performance. In other words, the initial parties to the contract guarantee the assignee will achieve the desired goal.

When Assignments Will Not Be Enforced

The following situations indicate when an assignment of a contract is not enforced:

  • The contract specifically prohibits assignment
  • The assignment drastically changes the expected outcome
  • The assignment is against public policy or illegal
  • The contract contains a no-assignment clause
  • The assignment is for a future right that only would be attainable in a contract in the future
  • The contract hasn't been finalized or written yet

Delegation vs. Assignment

Occasionally, one party in a contract will desire to pass on or delegate their responsibility to a third party without creating an assignment contract. Some duties are so specific in nature they cannot be delegated. Adding a clause in the contract to prevent a party from delegating their responsibilities and duties is highly recommended.

Characteristics of Assignments

An assignment involves the transfer by an assignor of some or all of its rights to receive performance under the contract to an assignee. The assignee then receives all the benefits of the assigned rights. The assignment doesn't eliminate or reduce the assignor's performance commitments to the nonassigning party.

Three Steps to Follow if You Want to Assign a Contract

There are three main steps to take if you're looking to assign a contract:

  • Make sure the current contract does not contain an anti-assignment clause
  • Officially execute the assignment by transferring the parties' obligations and rights
  • Notify the obligor of the changes made

Once the obligor is notified, the assignor will effectively be relieved of liability.

Anti-Assignment Clauses

If you'd prefer not to allow the party you're doing business with to assign a contract, you may be able to prevent this from occurring by clearly stating anti-assignment clauses in the original contract. The three most common anti-assignment clauses are:

  • Consent required for assignment
  • Consent not needed for new owners or affiliates
  • Consent not unreasonably withheld

Based on these three clauses, no party in the contract is allowed to delegate or assign any obligations or rights without prior written consent from the other parties. Any delegation or assignment in violation of this passage shall be deemed void. It is not possible to write an anti-assignment clause that goes against an assignment that is issued or ordered by a court.

Contract Assignments

(This may not be the same place you live)

  What is a Contract Assignment?

In a contract assignment, one of the two parties to a contract may transfer their right to the other’s performance to a third party. This is known as “contract assignment.” Generally, all rights under a contract may be assigned. A provision in the contract that states the contract may not be assigned usually refers to the delegation of the assignor’s (person who assigns) duties under that contract, not their rights under the contract. 

In modern law, the phrase “assignment of contract” usually means assignment of both rights and duties under a contract.

Who are the Various Parties Involved in a Contract Assignment?

How is a contract assignment created, when is a contract assignment prohibited, which parties are liable to each other in a contract assignment, are there issues with multiple assignments, should i hire a lawyer for contract assignments.

In a contract, there are two parties to the agreement, X and Y. The parties may agree to let X assign X’s rights to a third party . Once the third party enters the picture, each party has a special name. For instance, suppose X, a seller of bookmarks, contracts with Y, a purchaser of bookmarks. Y desires to have Y’s right to X’s performance (the sale of bookmarks on a monthly basis) to another person. 

This third person, Z, is called the assignee. X is called the obligor , and Y is called the assignor , since Y has assigned its right to X’s performance . X, the obligor, is obligated to continue to perform its duties under the agreement.

There are no “magic words” needed to create an assignment. The law simply requires that the would-be assignor have an intent to immediately and completely transfer their rights in the agreement. In addition, writing is typically not required to create an assignment. As long as X and Y both adequately understand what right is being assigned, an assignment is created. 

Words that indicate a transfer is to take place suffice, such as “I intend to transfer my rights under this agreement,” or, “I intend to give my rights to Z,” or “I intend to confer an assignment on Z.” In addition,consideration,which is a bargained-for exchange required for a contract to be valid, is not required for assignment.

In certain instances, an assignment of contract rights can be prohibited. If the contract contains a clause prohibiting assignment of “the contract,” without specifying more, the law construes this language as barring only delegation of the assignor’s duties, not their rights. If the assignment language states “assignment of contractual rights are prohibited,” the obligor may sue for damages if the assignor attempts to assign the agreement. If the contract language states that attempts to assign “will be void,” the parties can bar assignment.of rights.

Under modern contract law, the phrase “I assign the contract” is usually interpreted to mean that one is assigning rights and duties. What is an assignment of duties? An assignment of duties occurs where Y, called the obligor or delegator, promises to perform for X, the obligee. Y then delegates their duty to perform to Z, the delegate. Under the law, most duties can be delegated. 

There are exceptions to this rule. Delegation can be prohibited when:

  • The duties to be performed involve personal judgment and special skill (e.g., a portrait, creation of a custom-made dress). 
  • “Personal judgment” is the exercise of some kind of superior judgment when it comes to determining how, when, or where to do something. Examples of individuals who exercise personal judgment include talent scouts and financial advisors.  Special skill is the unique ability to create a good or perform a service. A delegator can be prohibited from delegating duties when it is that specific delegator’s services are sought. For example, if the services of a specific famous chef are sought, and the original agreement was entered into on the understanding that the chef was hired for their specific talent, the delegator may not delegate the services;
  • The assignment fundamentally changes risks or responsibilities under the agreement;
  • The assignment is over future rights associated with a future contract that does not currently exist;
  • Delegation would increase the obligation of the obligee. For example, if a shoe manufacturer contracts to deliver soles to a store in the same town as the shoe factory, the other party cannot assign the delivery to a different store in another state. Doing so would impose a greater obligation on the obligee than was originally contemplated;
  • The obligee had placed special trust in the delegator. For example, assume that you have hired a patent attorney, based on that attorney’s significant skill and expertise, to obtain a valuable patent. You have placed special trust in this person, hiring them instead of other patent attorneys, because of their unique expertise. In such a situation, the attorney may not delegate his duties to another attorney (delegate), since the attorney was hired because of one person’s special capabilities;
  • The delegation is of a promise to repay a debt; or
  • The contract itself restricts or prohibits delegation. If the contract states, “any attempt to delegate duties under this contract is void,” a delegation will not be permitted.

In a contract involving assignment of rights, the assignee may sue the obligor. This is because the assignee, once the assignee has been assigned rights, is entitled to performance under the contract. If the obligor had a defense that existed in the original contract between obligor and assignor, the obligor may assert that defense against the assignee. Examples of such defenses include the original contract was not valid because of lack of consideration, or because there was never a valid offer or acceptance).

An assignee may also sue an assignor. Generally, if an assignment is made for consideration,it is irrevocable. Assignments not made for consideration, but under which an obligor has already performed, are also irrevocable. If an assignor attempts to revoke an irrevocable assignment,the assignee may sue for “wrongful revocation.” 

In circumstances involving delegation of duties,an obligee must accept performance from the delegate of all duties that may be delegated. The delegator remains liable on the agreement. Therefore, the obligee may sue the delegator for nonperformance by the delegate. The obligee may sue the delegate for nonperformance, but can only require the delegate to perform if there has been an assumption by the delegate. An assumption by the delegate is a promise that the delegate will perform the delegated duty, which promise is supported by consideration. 

Assignments that are not supported by consideration are revocable. If an initial assignment is revocable, a subsequent assignment can revoke it. If a first assignment is irrevocable, because consideration was present,the first assignment will usually prevail over a subsequent assignment. This means the person who can claim the assignment was first made to them will prevail over someone who claims a subsequent assignment. 

If, however, the second person paid value for the assignment, and entered into the assignment without knowing of the first assignment, the “subsequent”assignee is entitled to proceeds the first judgment against the obligor (the original party who still must perform), in the event such a judgment is issued,

If you have an issue with assignment of rights or duties under a contract, you should contact a contract lawyer  for advice. An experienced business lawyer near you can review the facts of your case, advise you of your rights, and represent you in court proceedings.

Assignment provisions in contracts

Legal background: Contracts generally are freely assignable

When a party to a contract “ assigns ” the contract to someone else, it means that party, known as the assignor , has transferred its rights under the contract to someone else, known as the assignee , and also has delegated its obligations to the assignee.

Under U.S. law, most contract rights are freely assignable , and most contract duties are freely delegable, absent some special character of the duty, unless the agreement says otherwise. In some situations, however, the parties will not want their opposite numbers to be able to assign the agreement freely; contracts often include language to this effect.

Intellectual-property licenses are an exception to the general rule of assignability. Under U.S. law, an IP licensee may not assign its license rights, nor delegate its license obligations, without the licensor’s consent, even when the license agreement is silent. See, for example, In re XMH Corp. , 647 F.3d 690 (7th Cir. 2011) (Posner, J; trademark licenses); Cincom Sys., Inc. v. Novelis Corp. , 581 F.3d 431 (6th Cir. 2009) (copyright licenses); Rhone-Poulenc Agro, S.A. v. DeKalb Genetics Corp. , 284 F.3d 1323 (Fed. Cir. 2002) (patent licenses). For additional information, see this article by John Paul, Brian Kacedon, and Douglas W. Meier of the Finnegan Henderson firm.

Assignment consent requirements

Model language

[Party name] may not assign this Agreement to any other person without the express prior written consent of the other party or its successor in interest, as applicable, except as expressly provided otherwise in this Agreement. A putative assignment made without such required consent will have no effect.

Optional: Nor may [Party name] assign any right or interest arising out of this Agreement, in whole or in part, without such consent.

Alternative: For the avoidance of doubt, consent is not required for an assignment (absolute, collateral, or other) or pledge of, nor for any grant of a security interest in, a right to payment under this Agreement.

Optional: An assignment of this Agreement by operation of law, as a result of a merger, consolidation, amalgamation, or other transaction or series of transactions, requires consent to the same extent as would an assignment to the same assignee outside of such a transaction or series of transactions.

• An assignment-consent requirement like this can give the non-assigning party a chokehold on a future merger or corporate reorganization by the assigning party — see the case illustrations below.

• A party being asked to agree to an assignment-consent requirement should consider trying to negotiate one of the carve-out provisions below, for example, when the assignment is connection with a sale of substantially all the assets of the assignor’s business {Link} .

Case illustrations

The dubai port deal (ny times story and story ).

In 2006, a Dubai company that operated several U.S. ports agreed to sell those operations. (The agreement came about because of publicity and political pressure about the alleged national-security implications of having Middle-Eastern companies in charge of U.S. port operations.)

A complication arose in the case of the Port of Newark: The Dubai company’s lease agreement gave the Port Authority of New York and New Jersey the right to consent to any assignment of the agreement — and that agency initially demanded $84 million for its consent.

After harsh criticism from political leaders, the Port Authority backed down a bit: it gave consent in return for “only” a $10 million consent fee, plus $40 million investment commitment by the buyer.

Cincom Sys., Inc. v. Novelis Corp., No. 07-4142 (6th Cir. Sept. 25, 2009) (affirming summary judgment)

A customer of a software vendor did an internal reorganization. As a result, the vendor’s software ended up being used by a sister company of the original customer. The vendor demanded that the sister company buy a new license. The sister company refused.

The vendor sued, successfully, for copyright infringement, and received the price of a new license, more than $450,000 as its damages. The case is discussed in more detail in this blog posting.

The vendor’s behavior strikes me as extremely shortsighted, for a couple of reasons: First, I wouldn’t bet much on the likelihood the customer would ever buy anything again from that vendor. Second, I would bet that the word got around about what the vendor did, and that this didn’t do the vendor’s reputation any good.

Meso Scale Diagnostics, LLC v. Roche Diagnostics GmbH, No. 5589-VCP (Del. Ch. Apr. 8, 2011) (denying motion to dismiss).

The Delaware Chancery Court refused to rule out the possibility that a reverse triangular merger could act as an assignment of a contract, which under the contract terms would have required consent. See also the discussion of this opinion by Katherine Jones of the Sheppard Mullin law firm.

Assignment with transfer of business assets

Consent is not required for an assignment of this Agreement in connection with a sale or other disposition of substantially all the assets of the assigning party’s business.

Optional: Alternatively, the sale or other disposition may be of substantially all the assets of the assigning party’s business to which this Agreement specifically relates.

Optional: The assignee must not be a competitor of the non-assigning party.

• A prospective assigning party might argue that it needed to keep control of its own strategic destiny, for example by preserving its freedom to sell off a product line or division (or even the whole company) in an asset sale.

• A non-assigning party might argue that it could not permit the assignment of the agreement to one of its competitors, and that the only way to ensure this was to retain a veto over any assignment.

• Another approach might be to give the non-assigning party, instead of a veto over asset-disposition assignments, the right to terminate the contract for convenience . (Of course, the implications of termination would have to be carefully thought through.)

Assignment to affiliate

[Either party] may assign this Agreement without consent to its affiliate.

Optional: The assigning party must unconditionally guarantee the assignee’s performance.

Optional: The affiliate must not be a competitor of the non-assigning party.

Optional: The affiliate must be a majority-ownership affiliate of the assigning party.

• A prospective assigning party might argue for the right to assign to an affiliate to preserve its freedom to move assets around within its “corporate family” without having to seek approval.

• The other party might reasonably object that there is no way to know in advance whether an affiliate-assignee would be in a position to fulfill the assigning party’s obligations under the contract, nor whether it would have reachable assets in case of a breach.

Editorial comment: Before approving a blanket affiliate-assignment authorization, a party should consider whether it knew enough about the other party’s existing- or future affiliates to be comfortable with where the agreement might end up.

Consent may not be unreasonably withheld or delayed

Consent to an assignment of this Agreement requiring it may not be unreasonably withheld or delayed.

Optional: For the avoidance of doubt, any damages suffered by a party seeking a required consent to assignment of this Agreement, resulting from an unreasonable withholding or delay of such consent, are to be treated as direct damages.

Optional: For the avoidance of doubt, any damages suffered by a party seeking a required consent to assignment of this Agreement, resulting from an unreasonable withholding or delay of such consent, are not subject to any exclusion of remedies or other limitation of liability in this Agreement.

• Even if this provision were absent, applicable law might impose a reasonableness requirement; see the discussion of the Shoney case in the commentary to the Consent at discretion provision.

• A reasonableness requirement might not be of much practical value, whether contractual or implied by law. Such a requirement could not guarantee that the non-assigning party would give its consent when the assigning party wants it. And by the time a court could resolve the matter, the assigning party’s deal could have been blown.

• Still, an unreasonable-withholding provision should make the non-assigning party think twice about dragging its feet too much, becuase of the prospect of being held liable for damages for a busted transaction. Cf. Pennzoil vs. Texaco and its $10.5 billion damage award for tortious interference with an M&A deal.

• Including an unreasonable-delay provision might conflict with the Materiality of assignment breach provision, for reasons discussed there in the summary of the Hess Energy case.

Consent at discretion

A party having the right to grant or withhold consent to an assignment of this Agreement may do so in its sole and unfettered discretion.

• If a party might want the absolute right to withhold consent to an assignment in its sole discretion, it would be a good idea to try to include that in the contract language. Otherwise, there’s a risk that court might impose a commercial-reasonableness test under applicable law (see the next bullet). On the other hand, asking for such language but not getting it could be fatal to the party’s case that it was implicitly entitled to withhold consent in its discretion.

• If a commercial- or residential lease agreement requires the landlord’s consent before the tentant can assign the lease, state law might impose a reasonableness requirement. I haven’t researched this, but ran across an unpublished California opinion and an old law review article, each collecting cases. See Nevada Atlantic Corp. v. Wrec Lido Venture, LLC, No. G039825 (Cal. App. Dec. 8, 2008) (unpublished; reversing judgment that sole-discretion withholding of consent was unreasonable); Paul J. Weddle, Pacific First Bank v. New Morgan Park Corporation: Reasonable Withholding of Consent to Commercial Lease Assignments , 31 Willamette L. Rev. 713 (1995) (first page available for free at HeinOnline ).

Shoney’s LLC v. MAC East, LLC, No. 1071465 (Ala. Jul. 31, 2009)

In 2009, the Alabama Supreme Court rejected a claim that Shoney’s restaurant chain breached a contract when it demanded a $70,000 to $90,000 payment as the price of its consent to a proposed sublease. The supreme court noted that the contract specifically gave Shoney’s the right, in its sole discretion , to consent to any proposed assignment or sublease.

Significantly, prior case law from Alabama was to the effect that a refusal to consent would indeed be judged by a commercial-reasonableness standard. But, the supreme court said, “[w]here the parties to a contract use language that is inconsistent with a commercial-reasonableness standard, the terms of such contract will not be altered by an implied covenant of good faith. Therefore, an unqualified express standard such as ‘sole discretion’ is also to be construed as written.” Shoney’s LLC v. MAC East, LLC , No. 1071465 (Ala. Jul. 31, 2009) (on certification by Eleventh Circuit), cited by MAC East, LLC v. Shoney’s [LLC] , No. 07-11534 (11th Cir. Aug. 11, 2009), reversing No. 2:05-cv-1038-MEF (WO) (M.D. Ala. Jan. 8, 2007) (granting partial summary judgment that Shoney’s had breached the contract).

Termination by non-assigning party

A non-assigning party may terminate this Agreement, in its business discretion , by giving notice to that effect no later than 60 days after receiving notice, from either the assigning party or the assignee, that an assignment of the Agreement has become effective.

Consider an agreement in which a vendor is to provide ongoing services to a customer. A powerful customer might demand the right to consent to the vendor’s assignment of the agreement, even in strategic transactions. The vendor, on the other hand, might refuse to give any customer that kind of control of its strategic options.

A workable compromise might be to allow the customer to terminate the agreement during a stated window of time after the assignment if it is not happy with the new vendor.

Assignment – other provisions

Optional: Delegation: For the avoidance of doubt, an assignment of this Agreement operates as a transfer of the assigning party’s rights and a delegation of its duties under this Agreement.

Optional: Promise to perform: For the avoidance of doubt, an assignee’s acceptance of an assignment of this Agreement constitutes the assignee’s promise to perform the assigning party’s duties under the Agreement. That promise is enforceable by either the assigning party or by the non-assigning party.

Optional: Written assumption by assignee: IF: The non-assigning party so requests of an assignee of this Agreement; THEN: The assignee will seasonably provide the non-assigning party with a written assumption of the assignor’s obligations, duly executed by or on behalf of the assignee; ELSE: The assignment will be of no effect.

Optional: No release: For the avoidance of doubt, an assignment of this Agreement does not release the assigning party from its responsibility for performance of its duties under the Agreement unless the non-assigning party so agrees in writing.

Optional: Confidentiality: A non-assigning party will preserve in confidence any non-public information about an actual- or proposed assignment of this Agreement that may be disclosed to that party by a party participating in, or seeking consent for, the assignment.

The Delegation provision might not be necessary in a contract for the sale of goods governed by the Uniform Commercial Code, because a similar provision is found in UCC 2-210

The Confidentiality provision would be useful if a party to the agreement anticipated that it might be engaging in any kind of merger or other strategic transaction.

Materiality of assignment breach

IF: A party breaches any requirement of this Agreement that the party obtain another party’s consent to assign this Agreement; THEN: Such breach is to be treated as a material breach of this Agreement.

A chief significance of this kind of provision is that failure to obtain consent to assignment, if it were a material breach, would give the non-assigning party the right to terminate the Agreement.

If an assignment-consent provision requires that consent not be unreasonably withheld , then failure to obtain consent to a reasonable assignment would not be a material breach, according to the court in Hess Energy Inc. v. Lightning Oil Co. , No. 01-1582 (4th Cir. Jan. 18, 2002) (reversing summary judgment). In that case, the agreement was a natural-gas supply contract. The customer was acquired by a larger company, after which the larger company took over some of the contract administration responsibilities such as payment of the vendor’s invoices. The vendor, seeking to sell its gas to someone else at a higher price, sent a notice of termination, on grounds that the customer had “assigned” the agreement to its new parent company, in violation of the contract’s assignment-consent provision. The appeals court held that, even if the customer had indeed assigned the contract (a point on which it expressed considerable doubt) without consent, the resulting breach of the agreement was not material, and therefore the vendor did not have the right to terminate the contract.

Construction law terms: assignment and novation

14 Jul 2023, 12:44 pm

The terms ‘assignment’ and ‘novation’ are sometimes used interchangeably in relation to construction projects, but they are, in fact, very different.

While both involve bringing in a new party to the contractual arrangements, they have very distinct practical consequences. This guide examines the difference between both terms explains important differences, looks at how these differences have been illustrated in recent case law and offers some practical takeaways.

It is important to note that the ‘assignment’ of one party’s interest in a contract to another party is only partial, because the process only transfers the benefit of the first party’s interest. Assignment does not also transfer the first party’s obligations under that contract to the second party.

For example, the employer (Party A) under a building contract might assign the benefit of a collateral warranty granted to it by the contractor (Party B) or a subcontractor, to the purchaser of the development (Party C). That assignment does not transfer the burden of any of the employer’s obligations – they remain the same.

Another example showing how an assignment can only transfer the benefit of a contract, not the burden, under a building contract would be:

  • the developer’s rights to have the works constructed or to sue the building contractor if the works are defective, are benefits – so can be assigned;
  • the developer’s obligation to pay the contract price is a burden – so cannot be assigned.

The assignment of the benefit of a contract to Party C does not replace the parties to the original contract. However, after the assignment, Party C is entitled to the benefit of the contract and to enforce its rights against Party B. Party A cannot do so – as they have assigned those benefits onto Party C. However, because the burden has not transferred, Party A will remain liable to Party B for the performance of all obligations under the contract.

  • Construction law terms: design development and design change
  • Construction law terms: termination at common law and under contract
  • Construction law terms: claims under contract vs breach of contract claims
  • Construction law terms: contractual notices and condition precedent notices
  • Construction law terms: set off, abatement and counterclaims

The ordinary position is that an assignment will transfer the benefit of accrued and also of future rights. It is possible to agree something different – for example the transfer of future rights only – but clear and express words are required.

It is essential for parties that are considering assigning the benefit of a contract to check the terms of the contract first. This is because many contracts exclude or qualify the right to assignment, such as by limiting the number of times it can be assigned. By way of example, clause 7.1 of the standard form JCT Design and Build Contract 2016 states: “neither the Employer nor the Contractor shall without the consent of the other assign this Contract or any rights thereunder”.

In practice, however, this clause is very often amended, so parties must make sure to check the terms, and any schedule of amendments, carefully. 

One common amendment adds wording that the consent of the other party to assignment “shall not be unreasonably withheld or delayed”. While there is surprisingly little case law on what this means in practice, there is some authority to suggest that it means, at least, that the party required to provide consent must act honestly and in good faith, and must not withhold consent arbitrarily, capriciously or unreasonably.

Lastly, assignment can be statutory – sometimes referred to as ‘legal assignment’ – or equitable.  Statutory assignment must comply with the requirements of s.136 of the 1925 Law of Property Act, which includes a requirement to notify the other party to the contract (Party B) of the assignment in writing. If the assignment does not comply with the formalities in the Act, it will be an equitable assignment. 

The most pertinent difference between an equitable and statutory assignment is that the party (Party C) to whom the benefit is assigned cannot enforce in its own name and must join Party A in any action. This prevents Party B from being sued by Party C in circumstances where Party B has had no notice of the earlier assignment. 

If you want to transfer the burden of a contract as well as the benefit under it, you have to novate. In effect this creates a new contract between the two new parties and releases one of the parties from the contractual chain. The key requirement of novation is that it needs consent of all three parties involved. If Parties A and B have a contract between them, but Party A wishes to substitute Party C in its place then Parties A, B and C must all consent to this. 

Because the consent of all parties is required it will typically be documented in a tripartite agreement, signed by the novating party, the party to whom the contract is being novated and the third party. The agreement will in practice commonly be executed as a deed, otherwise some form of consideration must be provided by the party to whom the contract is being novated. 

If the parties do all consent to novation, the effect is that the original contract between Party A and B is extinguished and is replaced by a new one between Party B and C, which duplicates the rights and obligations of those under the original contract. Novation does not cancel past rights and obligations under the original contract, although the parties can agree to novate these as well.

In the context of a construction project, novation commonly occurs in design and build projects where the employer may engage consultants in the pre-construction design process. The building contract between the employer and contractor will often provide for the novation of these design consultants to the contractor. 

More generally, novation frequently occurs as a result of a company group restructuring or sale. On large infrastructure projects you might also see the novation of contracts to a special purpose vehicle (SPV) company that is set up specifically for the project. 

Key differences between assignment and novation

  Assignment  Novation
Requires consent of all parties?

No, unless there is an express restriction in your contract.

Yes – Parties A, B and C must all consent. 

Transfers the benefit under the contract?

Yes. Yes.

Transfers the burden under a contract?

No. Yes.

Replaces a party to a contract?

No.

Yes – Party C replaces Party A and takes up Party A’s rights and obligations going forward.

Case law involving assignment and novation

A good starting point is the Commercial Court case of The Argo Fund Ltd v Essar Steel Ltd, in which the judge summarised the four main differences between assignment and novation.

  • A novation requires the consent of all three parties involved. By contrast, Party A can assign without the consent of either Party B or Party C – unless the contract states otherwise.
  • A novation involves the termination of one contract and the creation of a new one in its place. In the case of an assignment Party A’s existing contractual rights are transferred to Party B, but the contract remains the same and Party A remains a party to it so far as its obligations are concerned.
  • A novation involves the transfer of both benefits and obligations to the new party, whereas an assignment concerns only the transfer of benefits.
  • Novation involves the termination of a contract and the creation of a new one so consideration is required, unless a party uses a deed which is generally enforceable without consideration. By contrast, assignment can be completed without the need for consideration.

Energy Works (Hull) Ltd v MW High Tech Projects UK Ltd

There are a number of cases where it has not been entirely clear whether a contract has been assigned or novated. A recent example is the 2020 ruling in the dispute between Energy Works (Hull) Ltd and MW High Tech Projects UK Ltd. The employer, Energy Works, engaged MW High Tech (MW) as a contractor. MW engaged Outotec as subcontractor.

The project did not go as planned and Energy Works terminated the main contract, which provided that, on termination, MW must assign its subcontracts to Energy Works. MW did so, but there was confusion over whether it retained the benefit of any accrued or future rights under the Outotec subcontract. 

MW’s primary case was that the assignment of the subcontract only assigned future rights, not accrued rights. It argued, therefore, that it could claim for these past breaches. Its alternative case was that if accrued and future rights were transferred, then properly construed the assignment also transferred accrued and future liabilities and therefore took effect as a novation. 

On the primary case, the judge found that the natural meaning of the words “ assign the sub-contract ” was to assign the benefit of all rights under that contract, both accrued and future. She explained that it is possible to retain accrued rights, which could form the basis of a claim, and assign future rights only, however clear words are needed and were absent here.

On the alternative case the judge disagreed that the transfer took effect as a novation. The parties called the transfer an assignment which, whilst not conclusive, was consistent with the wider factual background that suggested there was no intention for the subcontract to terminate and be replaced with a new one – as would occur with a novation.

The practical effect of this assignment was that MW had transferred away its right to pursue Outotec for damages, including any argument that its delay was what caused the termination. However, in a ‘double whammy’, MW remained liable to pay Outotec for works done under the subcontract and for any further works Outotec performed after the assignment.

At the same time, MW could not claim payment in respect of those works until the final account’s reckoning – which would not be until 90 days after eventual completion. MW remained liable to Energy Works for liquidated damages, replacement contractor costs and any defects. 

Practical implications

Assignment and novation are different ways of transferring an interest under a contract, but with very different practical effects; the terms should not be used interchangeably. Parties should be especially careful in relation to post-termination assignment or novation terms.

They should also be clear what they are trying to do from the outset and consider how it has to be documented – by notice of assignment or deed of novation. Parties should check the terms of their contract. Is there a prohibition or other restriction on assignment? They must ensure they comply with them. For a legal assignment, parties must follow the requirements of s.136 of the 1925 Law of Property Act. This includes a requirement to notify contract counterparties. 

If a party is assigning a contract, or is to be obliged to do so post termination, they should consider carefully whether they want to assign accrued and future rights. If they wish to do something different – for example by retaining accrued rights so they have a route to claim against a subcontractor – then clear words are needed.

Guideline for Drafting Partial Assignment:

A Partial Assignment is a legal document used when a party wishes to transfer only a portion of their rights or interests in a property, contract, or asset to another party. This assignment is often employed in business transactions, real estate, or when sharing specific rights without transferring the entire interest. When drafting a Partial Assignment, consider the following guidelines:

Clear Identification: Clearly identify the parties involved and provide specific details about the property, contract, or asset subject to partial assignment.

Detailed Terms: Clearly outline the specific rights or interests being transferred, specifying the scope and limitations of the partial assignment.

Consent and Approval: Obtain consent from all relevant parties and ensure compliance with any contractual or legal requirements governing the assignment.

Legal Review: Utilize precise legal language and seek legal counsel to ensure the document's enforceability and compliance with applicable laws.

Common Mistakes to Avoid:

Ambiguous Language: Avoid using vague or unclear language that may lead to misunderstandings about the extent of the partial assignment.

Failure to Obtain Consent: Obtain necessary consents from other parties involved, ensuring adherence to any contractual obligations.

Omission of Details: Ensure all relevant details are accurately provided to prevent disputes or confusion about the partial assignment.

Ignoring Legal Formalities: Adhere to any legal formalities or recording requirements to validate the partial assignment, especially in real estate or contractual matters.

By adhering to these guidelines and avoiding common mistakes, a Partial Assignment can be effectively drafted, facilitating the partial transfer of rights or interests while maintaining clarity and legal compliance in various business and contractual scenarios.
