An assignment of claims is a transfer of one party’s right to collect a payment or other financial benefit to a new holder, who then steps into the original party’s position and can enforce the claim directly. The party giving up the right is the assignor; the party receiving it is the assignee. Most commercial payment rights can be moved this way, and businesses rely on the mechanism constantly to turn future receivables into immediate cash or to pledge them as collateral. Whether a given transfer actually holds up, though, depends on meeting specific formal requirements and clearing both contractual and statutory restrictions.
Which Rights Can Be Transferred
The default legal rule favors assignability. A right moves to a new holder unless the contract itself or a statute says otherwise. Accounts receivable are the classic example: a company sells unpaid invoices to a financing firm for immediate capital. Rights to future contract payments, insurance proceeds, and claims for property damage or breach of contract all fit the same pattern.
Litigation claims are narrower. A party can sell an interest in a lawsuit involving property damage or breach of contract to an entity willing to fund the case. Personal injury claims are generally not assignable before judgment in most jurisdictions, a restriction meant to prevent the commercialization of bodily harm. Commercial payment rights stay liquid; claims tied to personal harm face tighter controls.
What Makes an Assignment Legally Valid
The assignor has to clearly express an intent to transfer the right immediately and completely. Language like “I plan to assign this later” or “I might give you this claim” falls short. Control over the claim has to leave the assignor’s hands at the moment of transfer, with no retained right to collect.
For assignments governed by Article 9 of the Uniform Commercial Code, the transfer becomes enforceable against the assignor and third parties only when three things line up: value has been given, the assignor has rights in the claim, and the assignor has signed an agreement that describes the specific claim in enough detail to distinguish it from other obligations. There is no minimum dollar amount that triggers the writing requirement under current UCC rules. Even so, putting any commercial assignment in writing is essential, because oral assignments are nearly impossible to enforce once a dispute arises.
Most commercial assignments involve consideration: the assignee pays the assignor a discounted amount for the right to collect the full claim. That exchange locks the transfer in place.
Gifts of Claims Can Be Revoked
A gratuitous assignment — a gift of the right to collect — is legally effective when made, but the assignor can take it back. Revocation can happen in several ways: the assignor notifies the assignee that the transfer is withdrawn, the assignor accepts the debtor’s payment directly, or the assignor assigns the same claim to someone else. The assignor’s death or bankruptcy also terminates a gratuitous assignment automatically.
An assignment supported by consideration is permanent. Once the assignee has paid, the assignor cannot undo the transfer unilaterally. Anyone paying money for an assigned claim should make sure the agreement recites the consideration exchanged, eliminating any later argument that the transfer was a revocable gift.
Notifying the Debtor
An executed assignment is not the end of the job. The assignee has to notify the debtor, the party who owes the money, that payments now go to the assignee. Until the debtor receives that notice, paying the original creditor in good faith satisfies the debt, and the debtor is protected from double liability.1Legal Information Institute. Uniform Commercial Code 9-406 – Discharge of Account Debtor; Notification of Assignment
Once a proper notification arrives, the debtor can only discharge the obligation by paying the assignee. Paying the original creditor after notice does not count, and a debtor who ignores a valid notification risks paying the full amount twice.1Legal Information Institute. Uniform Commercial Code 9-406 – Discharge of Account Debtor; Notification of Assignment
Under UCC Section 9-406, the notice has to reasonably identify the rights that were assigned. A vague letter saying “your account has been transferred” without specifying which obligation is at issue may not qualify. Good practice: name the specific obligation, instruct the debtor to redirect payments, identify the assignee, and send it by certified mail or another verifiable method to create a record of when it arrived.
Perfecting the Assignment With a UCC-1 Filing
Notice to the debtor protects the assignee against the debtor. Perfection protects the assignee against everyone else — other creditors, later assignees, and a bankruptcy trustee. For most assigned accounts and payment rights, perfection means filing a UCC-1 financing statement with the secretary of state’s office in the state where the assignor is organized (for businesses) or resides (for individuals). The filing must identify the assignor by exact legal name and describe the collateral.
Filing fees generally run $10 to $25 for electronic submissions, with higher charges in some states for paper or longer documents. A filing is effective for five years and has to be renewed by a continuation statement before it lapses. Letting a filing expire can strip perfected status and drop the assignee behind other creditors.
Priority When the Same Claim Is Assigned Twice
If an assignor transfers the same claim to two different parties, UCC Section 9-322 decides who wins. Between two perfected security interests, the earlier filing or perfection date takes priority. A perfected interest always beats an unperfected one, regardless of timing. If neither party perfected, the first assignment to attach controls.2Legal Information Institute. Uniform Commercial Code 9-322 – Priorities Among Conflicting Security Interests in and Agricultural Liens on Same Collateral An assignee who takes an assignment but never files is exposed to a later assignee who does file.
Defenses the Debtor Can Still Raise
An assignee does not receive a cleaner version of the claim than the assignor had. Under UCC Section 9-404, the debtor can raise any defense that existed in the original agreement with the assignor, plus any defense arising from that transaction. If the assignor delivered defective goods, that defect travels with the claim and can be asserted against the assignee.3Legal Information Institute. Uniform Commercial Code 9-404 – Rights Acquired by Assignee; Claims and Defenses Against Assignee
Unrelated claims against the assignor are also available to the debtor, but only if they arose before the debtor received notice of the assignment. New disputes with the assignor after that point cannot reduce what the debtor owes the assignee. And any counterclaim the debtor asserts can only offset the amount owed; it cannot generate an affirmative recovery against the assignee.3Legal Information Institute.

Restrictions That Can Block an Assignment
Anti-Assignment Clauses in Contracts
Many contracts prohibit either party from assigning rights without the other’s written consent. These clauses protect debtors from being forced to deal with unknown third parties, and violating one can breach the underlying contract or, in some jurisdictions, void the attempted transfer.
There is an important exception. Under UCC Section 9-406(d), a contractual term that prohibits or restricts the assignment of an account, payment right, or promissory note is generally ineffective. The UCC overrides these clauses to keep commercial financing flowing, so a business can sell its receivables to a financing company even if the underlying customer contracts say otherwise.1Legal Information Institute. Uniform Commercial Code 9-406 – Discharge of Account Debtor; Notification of Assignment This override applies to assignments governed by Article 9. Anti-assignment clauses in other settings, such as real estate leases or intellectual property licenses, may still be enforceable depending on the governing law.
Personal Service Contracts
A contract that depends on the unique skills or identity of a specific person cannot be assigned. Hiring a particular architect to design a building means the architect cannot pass that obligation to a different firm. The performer’s identity is central to the bargain.
Federal Benefits That Cannot Be Assigned
Several categories of federal benefits are shielded from assignment by statute, and no private agreement can override those protections.
- Social Security benefits: 42 U.S.C. § 407 blocks any transfer, assignment, garnishment, or seizure of the right to future payments. No other federal law can override this protection unless it expressly references Section 407.4Office of the Law Revision Counsel. 42 USC 407 – Assignment of Benefits
- Veterans’ benefits: 38 U.S.C. § 5301 bars assignment of VA compensation, pension, and dependency payments. Any arrangement in which a third party acquires the right to receive VA payments for consideration is treated as a prohibited assignment, even if structured as a repayment agreement. A beneficiary may voluntarily use benefit funds to repay a loan through separate, individually authorized payments.5Office of the Law Revision Counsel. 38 USC 5301 – Nonassignability and Exempt Status of Benefits
- ERISA pension benefits: employer-sponsored retirement plans must include an anti-alienation provision. Limited exceptions cover federal tax levies, qualified domestic relations orders in divorce, and small voluntary assignments that are revocable and do not exceed 10 percent of any benefit payment.6eCFR. 26 CFR 1.401(a)-13 – Assignment or Alienation of Benefits
Claims Against the Federal Government
Assignments involving federal contracts and money claims against the United States operate under stricter rules. Under 41 U.S.C. § 6305(a), a federal contractor cannot transfer the contract or any interest in it, and a transfer in violation voids the contract as to the government.7Office of the Law Revision Counsel. 41 USC 6305 – Prohibition on Transfer of Contract and Certain Allowable Assignments In parallel, 31 U.S.C. § 3727(b) prohibits assignment of a claim for money against the government until the claim has been allowed, the amount decided, and a payment warrant issued.8Office of the Law Revision Counsel. 31 USC 3727 – Assignments of Claims
Both statutes carve out a financing-institution exception. A contractor may assign money due or to become due under a federal contract to a bank, trust company, or other financing institution if the contract totals at least $1,000 and does not itself forbid the assignment.7Office of the Law Revision Counsel. 41 USC 6305 – Prohibition on Transfer of Contract and Certain Allowable Assignments Unless the contract says otherwise, the assignment must cover the full remaining balance, can only be made to a single party, and cannot be further reassigned. The assignee must file written notice and a true copy of the assignment with the contracting officer or agency head, any surety on a bond connected to the contract, and the disbursing officer designated to make payment.8Office of the Law Revision Counsel. 31 USC 3727 – Assignments of Claims Missing even one required recipient can leave the assignee with no enforceable right to collect from the Treasury.9Acquisition.GOV. Subpart 32.8 – Assignment of Claims
Bankruptcy Exposure If the Assignor Fails
An assignee who does not perfect before the assignor files bankruptcy faces the biggest downside in this whole area. Under 11 U.S.C. § 547(b), a bankruptcy trustee can claw back a transfer that was made to a creditor, on account of a pre-existing debt, while the debtor was insolvent, and within 90 days before the bankruptcy filing. For insiders such as family members, business partners, or affiliated entities, the look-back period stretches to one year. The transfer must also have given the creditor more than a standard liquidation would have provided.10Office of the Law Revision Counsel. 11 USC 547 – Preferences
Perfection is the assignee’s strongest defense. A properly perfected assignment supported by contemporaneous value, meaning the assignee paid for the claim at roughly the same time it was transferred, is much harder to unwind as a preference. An assignee who waits months to file a UCC-1, or never files at all, is betting on the assignor’s continued solvency. When that bet loses, the trustee can pull the assigned claim back into the estate and distribute it among all creditors.
