Assignment of Rights: Parties, Limits, and Novation

An assignment of rights is a transfer of the benefits owed to one party under an existing contract to a new third party, without ending or rewriting the original agreement. The person who was entitled to receive payment, delivery, or some other performance hands that entitlement to someone else, who then collects directly from the party on the hook. The underlying contract keeps running. Only the recipient of the benefit changes.

Done correctly, it’s a routine commercial move: companies assign receivables to raise cash, lenders sell mortgage servicing rights, and insurers transfer policy benefits. Done carelessly, it creates double-payment risk, accidental liability, and disputes about who is actually owed what. The mechanics below are what separates the two outcomes.

The Three Parties Involved

An assignment always has three roles. The assignor is the original party entitled to the benefit. The assignee is the new party receiving it. The obligor is the party who owes the duty or payment and now has to direct performance to someone different.

Once the transfer is complete, the assignee steps into the assignor’s shoes. The assignee gains every right the assignor had against the obligor, but no more than that. If the obligor had a valid defense against the assignor (the assignor breached first, for instance), that same defense works against the assignee. The assignor loses standing to collect or enforce the transferred right. If performance fails, the assignee can sue the obligor directly.

One point that trips people up: the obligor’s consent is not required. The assignor and assignee can complete the transfer between themselves. The obligor’s only protection is proper notice. Until notice arrives, the obligor can keep paying the assignor and get credit for it. After notice, payments to the assignor no longer count, and the obligor can end up paying twice.¹

Assignment Is Not Delegation

People regularly confuse assignment of rights with delegation of duties, and mixing them up has real consequences. An assignment transfers a benefit you’re entitled to receive. A delegation transfers a job you’re obligated to perform. The legal treatment is fundamentally different.

When you assign a right, it leaves your hands entirely. You no longer have standing to collect or enforce it. When you delegate a duty, you remain on the hook. No delegation of performance relieves the delegating party of any duty to perform or any liability for breach.² Hiring a subcontractor to handle work you owed under a contract does not free you from liability if the subcontractor botches it.

This matters in practice because a blanket transfer of “all my rights under the contract” is treated as both an assignment of rights and a delegation of duties. The assignee who accepts it implicitly promises to perform the assignor’s obligations, and either the assignor or the obligor can enforce that promise.² If you only want to move a specific right without picking up any duties, the document has to say so explicitly.

Rights That Cannot Be Assigned

The default rule is that most contractual rights are freely assignable. The exceptions share a common thread: an assignment should not unfairly change the deal for the party still obligated to perform.

When the Obligor’s Burden Would Materially Change

An assignment is blocked if substituting a new recipient would materially change what the obligor has to do, increase the obligor’s risk, or reduce the value of the obligor’s expected return performance.² A fire insurance policy is the classic example: assigning coverage to someone with a different risk profile changes the insurer’s exposure. Rights to receive a fixed sum of money almost always pass this test because paying $10,000 to a new recipient costs the obligor nothing extra. Rights tied to ongoing judgment calls or variable performance are where disputes arise.

Statutory and Public Policy Limits

Certain rights are off-limits regardless of what the contract says. Personal injury claims are generally non-assignable under common law in most jurisdictions, grounded in public policy concerns about encouraging litigation and protecting vulnerable claimants. Wage assignments face heavy restrictions at the state level, with many states capping the assignable percentage, requiring spousal consent, or banning the practice outright for certain debt types.

Anti-Assignment Clauses

Contracts often contain language prohibiting assignment. These clauses are enforceable, but their reach is narrower than most people assume. Under both the Restatement (Second) of Contracts and UCC Article 2, a clause barring assignment of “the contract” bars only delegation of the assignor’s duties, not the transfer of rights.² Even a clause specifically prohibiting assignment of rights does not necessarily void the transfer. Under the Restatement, such a clause gives the obligor a right to sue for damages but does not actually make the assignment ineffective. The right still passes to the assignee.

For businesses dealing with accounts receivable, the picture shifts further. UCC Section 9-406 renders anti-assignment clauses ineffective for assignments of accounts, payment rights, and promissory notes used as security interests, because modern commercial finance depends on the ability to factor receivables and use them as collateral. Narrow carve-outs apply to consumer obligations, health-care-insurance receivables, and outright sales of payment intangibles or promissory notes.¹

Paid Assignments vs. Gift Assignments

Whether the assignee paid for the right affects whether the assignment can be undone. An assignment backed by consideration (money, debt forgiveness, or other value from the assignee) is generally irrevocable the moment it’s made. The assignor cannot change their mind and reclaim the right.

A gratuitous assignment, where the assignor gives the right away as a gift, is different. The assignor can revoke it before certain hardening events occur. A gift assignment also terminates automatically if the assignor dies or makes a subsequent assignment of the same right to someone else. This creates real risk for the gratuitous assignee: if the assignor then assigns the same right to a second person who pays for it, the paying assignee wins.

A gift assignment becomes irrevocable when the assignee takes concrete action on it. Collecting payment from the obligor, obtaining a court judgment against the obligor, or receiving delivery of a symbolic writing like a promissory note all lock the assignment into place. Some jurisdictions also treat a written document showing clear intent to assign, once delivered, as sufficient to make the gift permanent. If you’re receiving an assignment without paying for it, get something in writing and act on it quickly.

What the Assignor Implicitly Promises

Every assignment carries implied promises from the assignor to the assignee, even if the document says nothing about them. The assignor warrants that the assigned right actually exists, that there are no undisclosed limitations or defenses that could undermine it, and that any document evidencing the right is genuine. The assignor also implicitly promises not to do anything that would interfere with the assignee’s ability to collect or enforce the right.

If an assignor transfers a right to payment that turns out to have already been extinguished by a prior breach, the assignee can pursue the assignor for damages. If the assignor collects from the obligor after completing the assignment, the assignee has a claim for that interference. These warranties only provide a remedy after the damage is done, so investigating the right before accepting it is still the better protection.

Writing the Assignment Document

A valid assignment does not require magic words. Courts look for a clear manifestation of the assignor’s intent to transfer the right in the present, not a promise to transfer it later. That said, a written document with specific details prevents the ambiguity that fuels litigation.

A workable assignment identifies:

The original contract, by date and parties, with enough detail that someone unfamiliar with it can locate the agreement.
The right being transferred, described precisely. A right to receive $12,000 in monthly $1,000 installments is far more useful than “all rights under the contract” if a partial transfer is what you intend.
All three parties, with names matching the original contract exactly.
Consideration given by the assignee, or an explicit statement that the assignment is a gift. Documenting consideration removes any question about revocability.
The effective date on which the assignee’s rights begin.

If the goal is to transfer only the right to receive benefits without assuming any of the assignor’s duties, say so plainly. A general assignment of “all rights under the contract” is treated as a delegation of duties too.² Careless language here is how people accidentally take on obligations they never intended.

Most assignments do not need to be in writing as a matter of law. Oral assignments are valid for most contract rights. Certain transfers fall under the Statute of Frauds and must be written: assignments of interests in land, assignments of rights under contracts that themselves must be in writing, and assignments of rights worth above the UCC’s threshold for goods transactions. Even where oral assignments are technically valid, proving what was agreed is hard enough that a written document is worth the effort.

Notifying the Obligor

Sending proper notice to the obligor is the single most important step after signing. Until the obligor receives an authenticated notification identifying the assigned rights and directing payment to the assignee, the obligor can discharge the obligation by paying the assignor.¹ After proper notice, the obligor must pay the assignee. Payments to the assignor after that point do not count, and the obligor faces the risk of paying the full amount a second time.

Under UCC Section 9-406, an effective notification must be authenticated by either the assignor or the assignee and must reasonably identify the rights that were assigned. A vague notice that fails to identify the specific account or obligation is ineffective. If you’re assigning only a portion of a larger account, the obligor can ignore the notice entirely and keep paying in full to the assignor, because the UCC allows the obligor to reject partial-payment instructions.¹

The obligor also has the right to request reasonable proof that the assignment actually happened. If the assignee fails to provide it within a reasonable time, the obligor can keep paying the assignor without liability.¹ Send notice by certified mail with a return receipt, include a copy of the signed assignment document, and be ready to provide further proof on request.

When You Need a Novation Instead

An assignment transfers benefits but leaves the assignor’s obligations intact. If the assignor wants a complete exit from the contract, including release from all duties and future liability, the right tool is a novation. A novation extinguishes the original contract entirely and replaces it with a new agreement between the obligor and the incoming party.

The critical difference is consent. An assignment can happen without the obligor’s agreement. A novation requires all three parties to sign off: the outgoing party, the incoming party, and the remaining party. Without unanimous consent, there is no novation, and the original party stays liable. This is the mechanism used in business acquisitions when the buyer wants to take over contracts cleanly, or when a partner leaves a firm and needs to be freed from existing client agreements. If you want to walk away entirely, make sure the obligor explicitly releases you in writing. An assignment alone, no matter how comprehensive its language, does not accomplish that.

Claims Against the Federal Government

Assignments involving claims against the U.S. government operate under a stricter set of rules. Under 31 U.S.C. § 3727, a claim against the government can be assigned only after the claim has been allowed, the amount decided, and a payment warrant issued. The assignment must be made freely, attested by two witnesses, and acknowledged before an official authorized to certify deeds.³

A narrower exception exists for financing arrangements. When a government contract provides for total payments of at least $1,000, the contractor can assign money due or to become due to a financing institution, provided the contract does not forbid it, the assignment covers the full unpaid amount, and the assignee files written notice with both the contracting agency and any surety on the contract bond.³ These assignments cannot be reassigned to a second party. A noncompliant assignment of a federal claim is simply void.

Tax Reporting Does Not Follow the Payment

Assigning the right to receive payment does not remove the income from anyone’s tax picture. The IRS still expects the income to be reported, and the general rule is that the party who earned the income or is the economic source of the funds remains responsible for reporting it, even if the check now goes to someone else. Where agents, property managers, or other intermediaries receive payments on behalf of the true owner of the right, the intermediary may need to file Form 1099-MISC reporting the payment to that owner.⁴ The assignment itself is not usually a taxable event, but the underlying income remains taxable to someone. A tax professional is worth the call before the first payment moves.
