Set-Off and Netting Rights Between Trading Partners

A party may generally withhold payment and apply a competing claim against it only where the two debts are mutual: owed between the same two parties, each acting in the same legal capacity. That is the core of set-off, and it is state law, so the precise contours differ from one jurisdiction to another. Contracts can expand the right through a netting clause, or remove it entirely through a no-set-off clause requiring payment without deduction. Bankruptcy adds a further layer of restrictions. Withholding without one of these footings is not a clever negotiating tactic — it is a breach of the payment obligation, and it is treated as one.

1.The mutuality test

Mutuality is the gatekeeper. Three conditions have to line up before a common-law set-off is available, and failing any one of them usually ends the analysis.

• The debts run between the same two persons or entities, not between related but distinct companies.
• Each party owes in the same capacity — an obligation owed personally cannot be set against one owed as trustee, agent, or fiduciary.
• The claims are debts rather than aspirations: mature obligations for a determinable sum, not open-ended damages estimates.

The third condition causes the most trouble. An unliquidated claim — the buyer believes the defective delivery cost it something, but has not established the amount — is a poor candidate for self-help set-off, even where a court might eventually allow it. States differ on setting an unliquidated claim against a liquidated debt, and the governing state sets the standard, which is why the choice-of-law term matters here as much as anywhere; see Choice of Law and Forum Selection: Drafting and Enforcement.

2.Set-off compared with recoupment

Set-off and recoupment are often used interchangeably in correspondence, and they are not the same thing. Set-off combines two independent obligations that happen to run in opposite directions between the same parties — an unpaid invoice on one contract against a damages claim on another. Recoupment reduces a claim by an amount arising from the very same transaction: the buyer does not owe the full invoice price because the goods delivered under that same order were short or defective.

The distinction is technical until a bankruptcy appears, and then it becomes decisive. Recoupment is generally treated as a limit on the amount of the claim itself rather than as a separate offsetting demand, and it is not confined by the same statutory restrictions that apply to set-off. Courts have not applied the line identically everywhere, and characterization arguments are common, but the drafting lesson is simple: obligations that are meant to be netted against each other are safer when they sit in a single agreement or in agreements expressly stated to form one transaction.

3.What a netting clause adds

Because the common-law right is narrow and fact-dependent, commercial parties usually write their own. An express set-off clause typically permits one side to deduct any amount owed to it under the agreement, or under any agreement between the parties, from any amount it owes. These clauses are generally enforced between businesses as ordinary contract terms.

Cross-affiliate netting is the harder version. A parent wants to set what its subsidiary is owed against what a different subsidiary owes to the counterparty. That structure breaks mutuality on its face, because the debts do not run between the same two entities. It can be made to work, but only with deliberate drafting: the affiliates are named, each consents in the agreement itself or by joinder, and the clause states that the parties intend the obligations to be treated as mutual for netting purposes. Without that, the clause is an invitation to litigation and is especially fragile once an insolvency proceeding is involved.

Close-out netting is the specialized form used in financial, energy, and commodity trading. On a defined default, all open transactions under a master agreement are terminated, valued, and reduced to a single net amount owed one way. It depends on the trades genuinely forming one master agreement rather than a loose collection of confirmations, which is why those documents say so expressly.

4.No-set-off clauses and assignment

The mirror image is the no-set-off clause: payment is due "in full, when due, without deduction, set-off, counterclaim, or withholding." These terms are standard in equipment leases, secured financings, and receivables purchases, and between businesses they are generally enforced. The logic is that a financier's willingness to advance money depends on a payment stream it can rely on, so quality disputes must be pursued as separate claims rather than by silence at the payment date.

Assignment interacts with all of this. When a receivable is sold or financed, the paying party's ability to assert set-off against the new holder is generally limited to claims that had already accrued against the original party before notice of the assignment. Claims arising afterward, on unrelated dealings, usually cannot be asserted against the assignee. That is why financiers ask for acknowledgments confirming no existing offsets, and why signing one without checking the ledger is risky.

Caution: Withholding payment without a right to do so is itself a breach, and it can trigger default interest, suspension of performance by the other side, termination rights, and cross-defaults in unrelated agreements. The consequences frequently exceed the amount in dispute, and a wrongly withheld payment can also convert a strong claim into a defensive posture.

5.What bankruptcy changes

Once a counterparty files, set-off stops being self-help. Section 553 of the Bankruptcy Code preserves whatever set-off right already existed under other applicable law — it does not create one. If the debts were never mutual, the filing does not make them mutual. The same section then restricts the preserved right, disallowing set-offs where the claim was acquired from a third party for the purpose of setting it off, and limiting offsetting positions built up during the window before the petition. Actually exercising a set-off after a filing also runs into the automatic stay, so the ordinary route is to seek relief rather than to act first; the scope of the stay is covered in The Automatic Stay: What It Halts and What It Does Not.

Payments and offsets taken close to a filing also attract avoidance scrutiny, a topic addressed in Preferences and Fraudulent Transfers: Clawing Payments Back. A creditor with a genuine set-off right is usually better off asserting it in the case rather than quietly netting on its own books, and the mechanics of participating are described in Proofs of Claim, Objections, and Creditor Participation. General information about how federal bankruptcy courts operate is published by the United States Courts.

6.Questions this raises

Can a buyer deduct the cost of defective goods from the next invoice?

Only where the contract allows deduction or the deduction arises from the same order. Reducing an invoice because the goods delivered under that same order were defective is usually recoupment and is on firmer ground. Deducting against a different order is a set-off, which needs mutuality and, in many contracts, express permission. A no-set-off clause defeats both. State law supplies the underlying standard.

Does a group-wide netting clause let a parent offset a subsidiary's debt?

Not automatically. Debts owed by and to separate legal entities are not mutual, so the common-law right does not reach them. A clause can achieve the result, but it has to identify the affiliates, secure their agreement to be bound, and state the parties' intention that the obligations be treated as mutual. Loose group-wide language often fails at the point when it matters most.

Is a no-set-off clause enforceable against a business that received defective goods?

Generally yes between merchants, though enforceability is a matter of state law and the clause's wording. The usual effect is procedural rather than substantive: the buyer must pay as agreed and pursue its quality claim separately, instead of resolving it by withholding. Consumer transactions are treated differently under additional federal and state rules, so business-to-business outcomes should not be read across.

If the counterparty is heading toward insolvency, is netting early a good idea?

Acting early on a real, already-mutual right is different from manufacturing one. Offsetting positions assembled shortly before a filing, or claims bought from third parties in order to net them, are precisely what the statutory restrictions target. Exercising set-off after a filing also collides with the automatic stay. The safer sequence is to confirm mutuality, document the existing right, and seek permission rather than act unilaterally.

7.Before withholding a payment

1. Read the payment clause first. Find out whether the agreement bars deduction outright before considering whether a right would otherwise exist.
2. Confirm the entities. Check that the same legal entity is on both sides of the two obligations, and in the same capacity.
3. Quantify the claim. An amount that can be calculated from the contract is a far stronger basis than an estimate of loss.
4. Check for an assignment. If the receivable has been sold or financed, work out when the competing claim accrued relative to notice.
5. Give written notice. State the amount, the obligation it is applied against, and the contractual or legal basis relied on.
6. Reassess if insolvency is near. Where a filing is likely, treat set-off as something to be authorized rather than assumed.
