Your China supplier's invoice for display cabinets is approaching its due date. A company you have never paid writes that it purchased the receivable and now owns the right to collect. Its message includes a different beneficiary. Calling the factory to check the account is necessary, but the buyer also needs to understand who is legally entitled to payment and whether paying that person will discharge this invoice.
The cabinets, claimant and messages are fictional illustrations, not customer transactions or real payment details. This article is general information, not legal advice. Counsel must assess assignment, notice, proof, defences and discharge under the applicable law. It provides no universal right to withhold a due payment.
Establish what the new recipient claims
An assignment of a right to payment is different from the supplier changing its own bank account or asking an agent to collect. Ask the claimant to identify its legal entity, the original creditor, the buyer whose debt it claims and the particular invoice or receivable. Determine whether it asserts ownership, collection authority or another arrangement.
The personal-account guide covers a different situation where the seller requests payment to an individual. Do not use an explanation for that arrangement as proof of a receivable assignment. The buyer needs the legal and documentary basis of this claim.
Finance should identify the remaining amount and currency, including earlier payments and accepted credits. A claimant's demand for the original invoice total may not match what remains outstanding. Do not acknowledge an unfamiliar amount simply to obtain new account details.
Authenticate the notice through established contacts
Use independently established supplier contacts to check whether the seller issued or recognises the assignment notice. The bank-details verification guide addresses that contact process. Avoid relying on a phone number supplied only in the new message, and preserve the notice with its receipt time and attachments.
Ask who signed for the supplier and whether that person had the relevant authority. A familiar logo or invoice reference does not establish authenticity. Equally, the supplier salesperson's surprise does not conclusively disprove an assignment they were not responsible for handling. Escalate conflicting answers to an authorised representative and counsel.
Keep a record of earlier notices or payment instructions for the same debt. If another company also claims the receivable, send both claims and their chronology for legal review rather than choosing the latest message.
Obtain proof that addresses this receivable
The UNIDROIT Principles 2016, Articles 9.1.10 to 9.1.13, address notice, successive assignments, adequate proof, defences and set-off. Article 9.1.12 addresses a request for adequate proof when notice comes from the assignee. These Principles are not automatically the law governing your purchase. Counsel must determine their relevance and the actual legal conditions before you rely on them.
Ask counsel what evidence is adequate for the case. It should connect the assignment to the creditor, debtor, covered invoice and amount. A generic statement that the supplier uses invoice finance may not establish that this debt was assigned to this claimant. Sensitive financing documents may need an appropriate confidential review route rather than public circulation.
A buyer's editorial review record could contain:
| Question | Evidence or decision to retain |
|---|---|
| Who claims the payment? | Verified entity and asserted role |
| Which debt is covered? | Buyer, supplier, invoice, remaining amount and currency |
| What notice was received? | Authenticated source, receipt date and chronology |
| What proves the assignment? | Counsel-assessed evidence linked to the debt |
| What remains disputed? | Earlier payments, credits, defences or competing claims |
| Who may be paid? | Legal review, approved beneficiary and payment authority |
These are editorial fields, not a legal opinion or a form of assignment.
Clarify discharge and unresolved claims
Ask counsel whether the proposed recipient is entitled to receive the payment and what evidence will show that the payment discharges the covered debt. Determine how the supplier and claimant will reflect the receipt in their records. A transfer receipt alone cannot settle a disputed question of creditor ownership.
Identify any outstanding defect claim, accepted credit or other defence. Assignment of the receivable does not, by itself, explain who will repair the cabinets or fulfil the seller's other obligations. Counsel should review the treatment of those matters and any available set-off rights. Do not assume every credit survives unchanged or that assignment transfers the whole supply contract.
The paid-shipment differences guide helps connect commercial documents to the payment history. Preserve that history when the creditor changes, including why an earlier beneficiary differs from the newly authorised one.
Resolve authority before issuing the new instruction
Give the payment provider the actual parties, relevant documents and proposed beneficiary through its approved review process. Legal acceptance of an assignment does not guarantee that a provider can execute that route. Do not relabel the claimant as the factory or suppress the third-party relationship to make the instruction appear routine.
Where proof or instructions conflict, obtain timely advice on the payment obligation and lawful next step. This article is not permission to miss a contractual due date, pay the old creditor regardless of notice or pay both claimants to end the discussion.
Use pay an invoice to ask A2vanta about the documented payment before funding. The buyer and counsel establish creditor entitlement and payment authority. Payment handling does not adjudicate the assignment or guarantee discharge of a disputed debt.
