Payment before the assignment notice arrives
Facts. Assume a covered commercial account with no relevant statutory exception. Forge transfers a $900 invoice to Finance on Sunday. Alder pays the full $900 to Forge on Monday, before any assignment notification; an otherwise effective authenticated payment direction first reaches Alder on Wednesday.
Analysis. Under 9-406(a), Monday’s payment can discharge this account because Alder has not yet received the notification. The later direction does not retroactively make that discharged $900 payable again.
Contrast the following practice question, where the debtor pays after receiving the notice. The Sunday transfer alone does not make the Monday payment ineffective; the difference is when Alder received the payment direction.
The rule
An assignment transfers a right; delegation concerns performance and does not by itself release the original obligor. Model UCC 2-210 governs specified goods-contract transfer limits. For covered payment rights, 9-404 and 9-406 distinguish defenses, notification, discharge and proof, with stated exceptions.
Elements
- An identified transferred right.
- The governing limits on assignment or delegation.
- Applicable notification, proof and defense rules.
Exceptions and limits
- A general goods-contract assignment ban may concern delegation only.
- Effective notification and proof requirements matter under 9-406.
- Section 9-404 distinguishes transaction defenses from other claims and limits certain offsets.
When the issue arises
Trace the transferred right. An invoice, an entire goods contract and an option may involve different restrictions, so an answer must classify the transaction before deciding whether an obligor can resist the transfer, assert a defense or discharge a debt by paying the original creditor. Assignment is not release. For a covered payment right, work through effective notification and any proof request before announcing whom payment satisfies.
A contract transfer can do more than one thing
Section 2-210 distinguishes assignment of rights from delegation of performance. General transfer language can include a delegate's undertaking, but the language or circumstances may point otherwise; delegation alone does not release the original party.
The same provision considers material changes in the other party's duty, burden, risk and chance of return performance. Identify what changes in fact, instead of assuming every transfer is harmless or forbidden.
Read both the restriction and its statutory qualification
Under 2-210(3), a general prohibition on assigning the contract ordinarily concerns delegation unless circumstances show otherwise. Subsection (2) separately protects specified rights after complete performance or whole-contract breach despite a contrary agreement.
Masterson illustrates why a claimed restriction may require evidence: it admitted proof of an alleged personal option without establishing that restriction as a fact. Do not use its remand as proof that every silent option is either transferable or personal.
Covered payment rights have notification safeguards
Section 9-406 addresses covered account debtors' discharge by paying the assignor until effective authenticated notification directing payment to the assignee. It also permits a request for reasonable assignment proof, with consequences if the assignee fails to supply it.
Apply the section's category and exceptions, including identification of the assigned rights, split-installment notices and other consumer rules. A message using the word assigned does not necessarily satisfy every requirement.
Separate transaction defenses from other claims
Section 9-404 distinguishes contract terms and transaction-based defenses or recoupment from other claims accruing before notification. It also limits certain claims to reducing the amount owed and preserves specified exceptions.
Do not assume an assignee takes free of every defense or is answerable for every later unrelated debt. The category, timing and applicable exception determine the result.
An unanswered proof request and an invoice defense
Facts. A covered account debtor receives an assignment notification and promptly requests reasonable proof. The assignee does not seasonably supply it, while the debtor has a transaction-based defense to part of the invoice.
Analysis. Section 9-406(c) can preserve discharge by payment to the assignor despite the notification when the proof requirement is unsatisfied, subject to applicable exceptions. Separately test the transaction defense under 9-404 rather than treating notice as erasing it.

- Treating delegation as a release of the original obligor.
- Reading every assignment ban as having identical scope.
- Ignoring notification effectiveness and reasonable proof requests.
- Combining all transaction defenses and later unrelated claims into one unlimited rule.
Practice questions
For a covered commercial account, a debtor receives effective authenticated notice identifying the assignment and directing full payment to the assignee. No statutory exception or unmet proof request applies. If the debtor pays the assignor anyway, what follows under 9-406(a)?
Answer and explanations
Correct answer: B.
Authority: UCC 9-406(a)-(c): notification and proof; UCC 9-404: defenses and claims
- A. Wrong. The timing and effective notice change the stated discharge rule.
- B. Correct. The assumed notification and absence of exceptions make payment to the assignor ineffective to discharge the obligation.
- C. Wrong. Section 9-404 separately preserves applicable defenses and claims; notice is not a blanket defense waiver.
- D. Wrong. Section 9-406 specifically governs the stated notification's effect.

Quick answers
Does an assignment release the original performer?
Delegation alone does not release the original party under 2-210. Examine any separate agreed substitution or release.
Does notification always require paying the assignee immediately?
For covered rights, 9-406 includes requirements for effective notification and a reasonable-proof provision. Apply its conditions and exceptions.
Does an assignee face every unrelated future claim?
Section 9-404 distinguishes transaction defenses and recoupment from other claims with a notification-based timing limit, and includes further exceptions.
