4.2 Assignment of Rights
Key Takeaways Explain This Topic AI
An assignment is a present transfer of a contractual right that extinguishes the assignor's right and vests it in the assignee.
No consideration is required for an effective assignment, but a gratuitous assignment is generally revocable while one for value is not.
A right is not assignable if the assignment would materially change the obligor's duty, materially increase the burden or risk, or is barred by statute or public policy.
A clause prohibiting assignment is usually read as a promise not to assign rather than a bar on the power to assign, so a breaching assignment is still effective and yields only damages.
As between successive assignees of the same right, the majority follows the first-in-time rule while the minority follows the English rule favouring the first to give notice to the obligor.

Assignment of Rights
Quick Answer: Contractual rights are assigned, while contractual duties are delegated. An assignment is a present transfer of a contractual right that completely extinguishes the assignor's right against the obligor. Consideration is not required for an assignment, but gratuitous assignments are revocable unless accompanied by a signed writing, delivery of a symbolic token, or detrimental reliance; assignments for value are irrevocable. Contractual anti-assignment clauses destroy the right to assign (giving the obligor a breach claim while the assignment remains valid) unless explicit voiding language ("null and void") destroys the power to assign. A delegation transfers performance of a duty; personal skill, artistic judgment, and confidential duties are non-delegable. Following a delegation, the delegator remains liable as a surety unless the obligee executes an express novation discharging the delegator.
Fundamentals: Assignment vs. Delegation
In everyday conversation, the word "assignment" is often used loosely to describe the transfer of an entire contract. In contract law, however, rights are assigned and duties are delegated :
Assignment of Rights: The transfer of a contractual benefit, claim, or right to receive performance from an assignor to an assignee.
Delegation of Duties: The transfer of an executory performance obligation, burden, or duty from a delegator to a delegatee.
The Four Contractual Roles
When rights and duties are transferred post-formation, four distinct legal roles emerge:
Obligor: The party who owes the performance obligation under the contract.
Obligee: The party to whom the contractual performance obligation is owed.
Assignor / Delegator: The original contracting party who assigns a right (assignor) or appoints another to perform a duty (delegator).
Assignee / Delegatee: The third party who receives the assigned right (assignee) or assumes the delegated duty (delegatee). Assignment of Rights vs. Delegation of Duties:
ASSIGNMENT (Rights / Benefits):
- [Assignor / Obligee] === Transfers Right to Collect ===> [Assignee]
- | ^
- |==== Original Duty to Pay / Perform ====| |
- v | |
- [Obligor] ===================================|==========|
- (Now owes performance directly to Assignee)
DELEGATION (Duties / Burdens):
- [Obligee] <===== (Expects Performance) ===== [Delegator]
- ^ |
- |========= (Appoints to Perform) =============>|
- | v
- |================ Performance =============== [Delegatee]
Contrast with Third-Party Beneficiaries: A third-party beneficiary is designated at the time the original agreement is formed. By contrast, assignment and delegation occur subsequent to formation , when an existing party transfers their rights or duties to a stranger to the initial transaction.
Assignment of Rights: Mechanics, Formality & Consideration
An assignment occurs when an obligee ( assignor ) manifests an intention to transfer a contractual right to a third party ( assignee ), so that the assignor's right to performance is extinguished and the assignee acquires a direct right to demand performance from the obligor .
Manifestation of Present Intent
To effectuate an assignment, the assignor must manifest an immediate, present intent to completely divest themselves of the right. No special "magic words" are required, but the language must convey a present transfer:
Sufficient Present Language: "I hereby assign," "I transfer to you now," or "I convey my right to receive payment to Assignee."
Insufficient Future Commitments: A promise to assign in the future ("I promise to assign my contract to you next month") is not an assignment; it is merely an executory promise. Similarly, a promise to pay out of a future fund ("I will pay you $10,000 as soon as the general contractor pays me") is not an assignment, because the obligee retains control over the fund and manifests no intent to transfer direct ownership of the claim.
Formalities & Consideration
No Writing Required at Common Law: An oral assignment is generally valid, unless the subject matter falls within the Statute of Frauds (e.g., assignment of a land sale contract or a right to performance that cannot be completed within one year) or a specific regulatory statute (e.g., wage assignments or transfers of government claims).
Consideration Not Required: Consideration is not necessary to make an assignment effective. An assignment may be supported by consideration (an assignment for value ) or made as a gift (a gratuitous assignment ).
Gratuitous Assignments vs. Assignments for Value
The presence or absence of consideration fundamentally determines whether an assignment is revocable .
1. Gratuitous Assignments (Gift Assignments)
A gratuitous assignment is given without consideration. As a general rule, a gratuitous assignment is freely revocable by the assignor.
Methods of Revocation: A gratuitous assignment is revoked if the assignor:
- Communicates notice of revocation to the assignee or the obligor;
- Accepts performance directly from the obligor;
- Subsequently assigns the identical right to a different party; or
Dies or becomes bankrupt.
Exceptions to Revocability (Irrevocable Gratuitous Assignments): A gratuitous assignment becomes irrevocable if:
It is memorialized in a signed writing delivered by the assignor to the assignee;
It is accompanied by delivery of a symbolic token or tangible document embodying the right (e.g., a bank passbook, stock certificate, or promissory note); or
The assignee materially and detrimentally relies on the assignment in a reasonable and foreseeable manner (promissory estoppel under Restatement § 90).
2. Assignments for Value
An assignment is for value if it is given in exchange for consideration, or as security for or satisfaction of a pre-existing debt. An assignment for value is irrevocable.
Implied Warranties of an Assignor for Value
Under Restatement (Second) of Contracts § 333 , an assignor for value makes three implied warranties to the assignee upon transferring the right:
Genuine Right: The assigned right actually exists and is subject to no undisclosed defenses or limitations;
No Impairment: The assignor will do nothing to defeat or impair the value of the assignment, and has not previously assigned the same right;
Authentic Documents: Any documentation delivered to the assignee is genuine and what it purports to be.
Exam Trap: The assignor does not warrant that the obligor is solvent or will perform the contract. The risk of the obligor's financial collapse, insolvency, or unexcused breach falls squarely upon the assignee.
Priority Between Successive Assignments of the Same Right
What happens when an unscrupulous assignor assigns the exact same contractual right twice?
Successive Gratuitous Assignments: The last assignee wins. Because gratuitous assignments are revocable, each subsequent assignment automatically revokes all prior gratuitous assignments.
Successive Assignments for Value: The traditional majority common law rule is "first in time is first in right" —the first assignee for value acquires legal ownership of the right.
The Restatement § 342 / "Four-Stop" Exception: A subsequent assignee for value who takes in good faith, without notice of the prior assignment, prevails over the first assignee if the subsequent assignee:
- Obtains payment or satisfaction from the obligor;
- Recovers a final judgment against the obligor;
- Enters into a new contract (novation) with the obligor; or
Obtains possession of the tangible token or document embodying the right.
Limitations on Assignability & Anti-Assignment Clauses
Under modern law and UCC § 2-210(2) , contractual rights are presumptively freely assignable. However, two primary barriers can restrict assignment: substantive common law limitations and contractual prohibitions.
Substantive Limitations: Material Alteration of Duty or Risk
A right cannot be assigned if the assignment would:
- Materially change the duty of the obligor;
- Materially increase the burden or risk imposed on the obligor by the contract; or
Materially impair the obligor's chance of obtaining return performance.
Examples of Substantive Limitations
Personal Service Contracts: The right to receive personal services requiring individual taste or personal interaction cannot be assigned. A homeowner who contracts with a personal fitness trainer cannot assign the right to training sessions to a neighbor, because training a different individual materially alters the trainer's duty.
Property & Casualty Insurance: A homeowner cannot assign a property fire insurance policy to a buyer when selling a house, because the insurer underwrote the specific risk and moral character of the original insured. (Note: Assigning the right to insurance proceeds after a loss has occurred is always permitted, as it is merely a right to collect money).
Output & Requirements Contracts (UCC § 2-306 / § 2-210): A buyer's requirements contract can be assigned only if the assignee's requirements are not unreasonably disproportionate to the original assignor's historical operations.
Contractual Prohibitions: The Doctrinal Spectrum
Parties frequently include "anti-assignment clauses" in their contracts. Because the law disfavors restraints on the alienation of property, courts construe these clauses strictly. On the FYLSE, you must categorize the clause into one of three distinct categories: Contractual Anti-Assignment Hierarchy:
1. Prohibition of "The Contract" --> Bars DELEGATION only; Rights assignable.
2. Prohibition of "Assignment" --> Destroys RIGHT, not Power; Assignment is VALID.
3. Clause stating "Void" --> Destroys POWER to assign; Assignment is NULL.
- 1. Prohibition of "The Contract"
- Contract Language: "This contract may not be assigned," or "Neither party may assign this agreement."
Legal Effect (Restatement § 322; UCC § 2-210(3)): Construed as prohibiting only the delegation of performance , not the assignment of rights to receive payment. The assignment of rights remains completely valid.
2. Prohibition of Rights (Destroys Right, Not Power)
Contract Language: "Rights under this contract shall not be assigned," or "Neither party may assign any right without prior written consent."
Legal Effect: Destroys the assignor's right to assign, but NOT the power to assign.
Consequence: The assignment is legally valid and enforceable . The obligor must pay the assignee! However, because the assignor breached the negative covenant not to assign, the obligor may sue the assignor for damages caused by the breach (which are usually nominal in payment assignments).
3. Voiding Clauses (Destroys Power)
Contract Language: "Any attempted assignment of rights shall be void," "null and void," or "of no legal force or effect."
Legal Effect: Destroys both the assignor's right and the power to assign.
Consequence: The attempted assignment is completely invalid, ineffective, and void ab initio . The assignee acquires no legal rights against the obligor, and the obligor may safely disregard the assignment.
4. UCC Statutory Protection: Damages for Breach (UCC § 2-210(2))
Under UCC § 2-210(2), regardless of any contractual prohibition, a party may always assign a right to damages for breach of the whole contract, or a right arising out of the assignor's due performance of their entire obligation (e.g., an account receivable).
