California Bar Assignment/delegation
Last updated: May 2, 2026
Assignment/delegation questions are one of the highest-leverage areas to study for the California Bar. This guide breaks down the rule, the elements you need to recognize, the named traps that catch most students, and a memory aid that scales to test day. Read it once, then practice the same sub-topic adaptively in the app.
The rule
An assignment is a present transfer of an existing contract right from the assignor to the assignee, extinguishing the assignor's right and giving the assignee the power to enforce it directly against the obligor. A delegation is the appointment of another (the delegate) to perform the delegator's contractual duties; the delegator remains liable unless the obligee expressly releases the delegator (a novation). Under common law and UCC § 2-210, all rights are assignable and all duties are delegable EXCEPT where (a) assignment would materially change the obligor's duty, materially increase the risk, or materially impair the chance of return performance; (b) the contract validly prohibits assignment/delegation; or (c) the duty is personal (involving special skill, judgment, trust, or output/requirements based on the delegator's particular operations). A clause barring "assignment of the contract" is presumptively read as barring delegation of duties only, leaving rights assignable; a clause barring assignment of rights is enforceable but breach (not voidness) is the default remedy unless the contract or statute makes the assignment void.
Elements breakdown
Valid Assignment of Rights
A present transfer of an existing contractual right from assignor to assignee that extinguishes the assignor's right and gives the assignee standing to enforce against the obligor.
- Existing contract right held by assignor
- Present intent to transfer (not a future promise)
- Adequate manifestation (writing if required by Statute of Frauds)
- Right not materially altered by the transfer
- No effective contractual or statutory bar
Common examples:
- Assignor sells outstanding accounts receivable to a factor
- Beneficiary of a money judgment assigns the judgment to a creditor
- Painter assigns right to be paid to her supplier
Valid Delegation of Duties
Appointment of a delegate to perform the delegator's duties under a contract, leaving the delegator secondarily liable unless released by novation.
- Existing contractual duty held by delegator
- Manifestation of intent to have delegate perform
- Duty not personal (no special skill/trust/judgment)
- No effective contractual or statutory bar
- Delegator remains liable absent novation
Common examples:
- General contractor delegates framing to a subcontractor
- Seller of fungible goods delegates manufacture to a third-party plant
Non-Assignable Rights (Exceptions)
Categories where an attempted assignment is ineffective because the transfer would unfairly burden the obligor or violate law.
- Materially changes obligor's duty
- Materially increases obligor's risk or burden
- Materially impairs obligor's chance of return performance
- Assignment prohibited by statute (e.g., some government claims, future wages in some jurisdictions)
- Assignment validly barred by contract that makes assignment void
Common examples:
- Assignment of a personal-services right to a different employer
- Assignment of an output/requirements right to a buyer with much larger demand
- Assignment of a malpractice claim (in many jurisdictions)
Non-Delegable Duties (Exceptions)
Duties that may not be delegated because the obligee has a substantial interest in performance by the original promisor.
- Duty calls for personal skill, judgment, or taste
- Obligee has substantial interest in delegator's performance
- Contract validly prohibits delegation
- Statute prohibits delegation
Common examples:
- Portrait painter's duty to paint
- Lawyer's duty to represent a particular client
- Lead singer's duty to perform at a concert
Anti-Assignment Clauses — Construction
How courts read clauses purporting to forbid assignment, with the strong default favoring assignability of rights.
- Clause barring 'assignment of the contract' bars delegation only (rights remain assignable)
- Clause barring assignment of rights is enforceable
- Default remedy is breach, not voidness, unless contract or statute makes assignment void
- Right to receive money damages for breach is generally assignable despite the clause
- Clause does not bar assignment by operation of law (death, merger) absent clear language
Common examples:
- 'Neither party may assign this Agreement' = duties non-delegable, rights still assignable
- 'Any assignment shall be void' = assignment ineffective, not just breach
Novation vs. Mere Delegation
A novation discharges the original promisor; a delegation does not.
- Valid prior obligation
- Agreement among all three parties (obligee, delegator, delegate)
- Express release of delegator by obligee
- New valid contract substituted
- Without all four, delegator remains liable as surety
Common examples:
- Buyer of business expressly assumes seller's debts and creditor signs release
- Tenant assigns lease and landlord signs estoppel releasing original tenant
UCC § 2-210 Special Rules
Article 2 governs assignment and delegation in sales of goods, with rules slightly more permissive than common law.
- All rights assignable unless materially changing obligor's duty/risk
- Right to damages for breach of whole contract always assignable
- Acceptance of assignment of 'the contract' is also a delegation of duties and a promise by assignee to perform
- Obligee may treat any delegation of performance as creating reasonable grounds for insecurity and demand assurances under § 2-609
Common examples:
- Buyer assigns right to delivery and seller may demand assurances from assignee
- Seller assigns 'the contract' to successor; successor impliedly promises to perform
Common patterns and traps
The Anti-Assignment Clause Overreach
A distractor invokes a contract clause prohibiting 'assignment of the contract' and concludes that the assignee cannot collect money owed. This misreads the default rule: under Restatement (Second) § 322 and UCC § 2-210(4), such a clause bars delegation of duties only, leaving the right to receive payment assignable. Even a clause that bars assignment of rights typically gives rise to a breach action against the assignor, not voidness of the assignment, unless the contract specifically says 'any assignment shall be void.'
A choice that says 'No, because the contract prohibits assignment' when the only thing transferred was the right to receive money.
The Phantom Novation
A choice assumes the original promisor was discharged simply because a delegate was named or because the obligee accepted performance from the delegate. Acceptance of substitute performance is not a release. A novation requires a tripartite agreement and an express release of the delegator by the obligee.
A choice that absolves the delegator of liability when nothing in the facts shows the obligee released her.
The Personal-Services Mislabel
A distractor labels a routine duty as 'personal' to block delegation, or treats a genuinely personal duty as routine. The test is whether the obligee bargained for the particular promisor's skill, taste, or judgment. Hauling, fungible-goods manufacture, and standardized services are delegable; portraits, legal representation, and headlining performances are not.
A choice barring delegation of routine commercial work by calling it 'personal,' or permitting delegation of a custom artistic commission.
The Material-Change Mirage
The choice argues an assignment fails because it inconveniences the obligor in some minor way (different remit address, different invoicing). Material change means change in the obligor's actual duty, risk, or chance of return performance — not administrative friction. UCC § 2-609 demand for assurances is the obligor's remedy for legitimate insecurity, not a veto.
A choice rejecting an assignment because the obligor 'now has to deal with a stranger,' without any change in what the obligor must do.
The Output/Requirements Switch
Assignment of a requirements buyer's rights to a much larger buyer (or an output seller's rights to a smaller producer) is the textbook material-change scenario because it transforms the obligor's quantity exposure. Bar distractors flip this — sometimes calling it valid because requirements/output contracts are 'just sales of goods.' UCC § 2-306 polices the quantity term, and § 2-210 polices the assignment.
A choice approving assignment of a requirements right from a corner café to a national chain.
How it works
Start by separating the two halves of the question: who is transferring a RIGHT (to receive performance, usually money) and who is transferring a DUTY (to render performance). Reyes contracts to landscape Liu's office park for $50,000. If Reyes transfers her right to the $50,000 to her bank, that is an assignment of a right — almost always valid because Liu still pays the same dollars to a different payee. If Reyes hands the actual landscaping work to her cousin Patel, that is a delegation, and the question becomes whether the duty is personal. Because landscaping is routine labor, not a personal-services duty, delegation is allowed — but Reyes remains on the hook unless Liu expressly releases her in a novation. Now flip to a portrait commission: the duty is non-delegable because the obligee bargained for that particular artist's hand. The bar tests this exact two-step constantly, and the trap is treating an anti-assignment clause as nuking everything; by default, such a clause only blocks delegation of duties.
Worked examples
Will the Bank prevail?
- A No, because the contract expressly prohibits assignment without written consent, and the Bank never obtained Liu's consent.
- B No, because Liu's tender to Reyes discharged Liu's obligation regardless of the assignment.
- C Yes, because a clause barring 'assignment of the Agreement' is construed to prohibit only delegation of duties, leaving the right to receive money assignable. ✓ Correct
- D Yes, because anti-assignment clauses in service contracts are unenforceable as a matter of public policy.
Why C is correct: Under Restatement (Second) of Contracts § 322 and the parallel rule in UCC § 2-210(4), a clause that bars 'assignment of the contract' or 'assignment of this Agreement' is presumptively read to bar delegation of duties only; the right to receive money payments remains freely assignable. Reyes did not delegate her landscaping work — she kept performing — and only transferred her right to the money. Once the Bank gave Liu notice of the assignment, Liu's duty ran to the Bank, and tendering payment to Reyes did not discharge that duty.
Why each wrong choice fails:
- A: This treats the anti-assignment clause at face value, but the default construction limits such a clause to barring delegation of duties, not assignment of the right to receive money. Even if the clause did reach this assignment, the typical remedy would be breach by Reyes, not voidness of the assignment. (The Anti-Assignment Clause Overreach)
- B: Once Liu received notice of the assignment, Liu's payment duty ran to the Bank as assignee. Payment to the assignor after notice does not discharge the obligor's duty to the assignee.
- D: Anti-assignment clauses are not categorically void; they are construed narrowly. The Bank wins because of construction, not invalidation, and overstating the rule is itself a graded error. (The Anti-Assignment Clause Overreach)
Is Hartwell justified in refusing to accept Okafor's performance?
- A No, because under modern contract law all duties are delegable absent an express anti-delegation clause, and there is none here.
- B No, because Patel remains secondarily liable on the contract, so Hartwell suffers no prejudice from the delegation.
- C Yes, because Hartwell may treat the assignment as creating reasonable grounds for insecurity and demand adequate assurances.
- D Yes, because the duty calls for the personal skill and artistic judgment of Patel, making it non-delegable. ✓ Correct
Why D is correct: A duty is non-delegable when the obligee has a substantial interest in performance by the particular promisor — the classic example is a duty calling for special artistic skill, taste, or judgment. Hartwell bargained for a Patel portrait, not 'a portrait by whoever Patel chooses.' The attempted delegation is ineffective, and Hartwell may treat Patel's announcement that Okafor will perform as anticipatory repudiation.
Why each wrong choice fails:
- A: This overstates the modern rule. Restatement (Second) § 318 and UCC § 2-210(1) both carve out duties in which the obligee has a substantial interest in personal performance, and an express clause is not required to invoke the exception. (The Personal-Services Mislabel)
- B: Continuing secondary liability of the delegator does not cure a non-delegable duty. The obligee bargained for performance by the particular promisor, and money damages from the original promisor is not a substitute. (The Phantom Novation)
- C: The § 2-609-style assurances remedy is a UCC Article 2 device for sales of goods and addresses delegations that are otherwise valid. A portrait commission is a services contract, and the duty here is non-delegable on its face — Hartwell's right is to refuse, not merely to demand assurances. (The Material-Change Mirage)
What is the likely outcome?
- A Mendoza prevails, because the assignment materially changes the obligor's duty and risk under UCC § 2-210. ✓ Correct
- B Mendoza prevails, because requirements contracts are personal and may never be assigned.
- C Pacific Bean prevails, because under UCC § 2-306 the buyer's requirements control, regardless of who the buyer is.
- D Pacific Bean prevails, because Mendoza's exclusive remedy is to demand adequate assurances under UCC § 2-609 before refusing to perform.
Why A is correct: UCC § 2-210(2) permits assignment of contract rights unless the assignment would materially change the duty of the other party or materially increase the burden or risk imposed on him. Assigning a requirements right from an 800-pound-per-month café to a 30,000-pound-per-month chain is the paradigm material change in quantity exposure. The assignment is ineffective to the extent it expands Mendoza's obligation beyond Coastal's reasonable historical requirements.
Why each wrong choice fails:
- B: Requirements rights are not categorically non-assignable. They are assignable so long as the assignee's requirements are reasonably proportionate to the assignor's; the rule polices material change, not identity. (The Personal-Services Mislabel)
- C: UCC § 2-306 limits the buyer's requirements to amounts not unreasonably disproportionate to stated estimates or prior course of dealing, and § 2-210 independently bars an assignment that materially changes the seller's exposure. The choice ignores both limits. (The Output/Requirements Switch)
- D: Section 2-609 is available when an obligee has reasonable grounds for insecurity about an otherwise valid assignment or delegation. Where the assignment itself is ineffective under § 2-210(2) for material change, the obligor is not required to first run the assurances procedure before refusing the expanded performance. (The Material-Change Mirage)
Memory aid
RAD-DUMP: Rights are Assignable by Default; Duties are Usually delegable, except Materially-changing or Personal. If a clause says 'no assignment of the contract,' read it as 'no Delegation' — rights still flow.
Key distinction
Assignment transfers rights and extinguishes the assignor's claim; delegation transfers performance but leaves the delegator secondarily liable unless the obligee expressly releases her in a novation. The grader is hunting for the candidate who collapses these two and forgets the continuing liability point.
Summary
Rights are freely assignable and duties are freely delegable unless the transfer materially changes the obligor's position, the duty is personal, or the contract or a statute validly forbids it — and even then, anti-assignment clauses are read narrowly and delegators remain liable absent a novation.
