Legal provisions & enforcement — three clauses that decide whether deferred payments are collectable.

In a 2026 deal market where deferred payments often comprise 20–40% of the purchase price, three contract provisions decide whether that deferred consideration actually arrives. Most sellers focus on the headline number. The skilled ones focus on these three clauses, because they are the ones that turn the headline into a wire transfer.

§ 01 · Set-Off RightsUnrestricted vs. arbitrated.

Set-off rights grant the buyer the ability to deduct alleged damages directly from future payments owed to the seller — seller notes, earnouts — without a court order. The structure of these rights is one of the most consequential provisions in any deal involving deferred consideration.

Unrestricted set-off (self-help). Under an unrestricted clause, if the buyer alleges a breach ("client retention was misrepresented"), they can unilaterally stop making note payments to offset the claimed damage. This creates a hostage mechanism — the seller's own withheld capital effectively funds the buyer's litigation defense, because the seller must now sue to resume payments. The burden of proof shifts entirely to the seller. The deferred income stream becomes a contingent liability subject to buyer discretion.

Arbitrated and restricted set-off (the defense). Three components form the standard defense. Set-off should be permitted only for amounts the seller explicitly agrees to in writing — undisputed claims only. Disputed claims must be validated by a third-party arbitrator or final non-appealable court judgment before funds are withheld. And as a compromise, disputed funds should be placed into a neutral escrow account rather than remaining with the buyer — this removes the buyer's incentive to manufacture claims solely to preserve working capital.

§ 02 · Cross-Default ClausesAvoiding Passive Default Limbo.

A cross-default clause stipulates that a default on the buyer's senior debt automatically triggers a default on the seller note. This is essential because sellers accepting a seller note alongside bank-financed acquisitions are almost always subordinated creditors.

Without cross-default, a buyer can be insolvent and defaulting on their bank loan while keeping the seller note technically "current" — or frozen by subordination. The seller is in Passive Default Limbo: unable to accelerate the debt or take legal action because the seller's specific note has not been technically breached, even as the buyer's financial position deteriorates.

Cross-default fixes this. When the bank declares default, the seller can immediately declare default and accelerate the outstanding balance. Actual payment may still be blocked by the subordination agreement, but establishing the claim provides two critical benefits: the right to participate in workout negotiations, bankruptcy proceedings, and restructuring discussions alongside senior lenders; and formal legal standing as a creditor — without a declared default, the seller may be excluded from these tables entirely.

§ 03 · Anti-SandbaggingThe Delaware default and the knowledge waiver.

Sandbagging is when a buyer closes a deal knowing the seller has breached a representation — aware of a pending lawsuit not disclosed, say — stays silent, and sues for indemnification immediately after closing. The buyer prices the known risk into the deal (lowering the multiple) and also sues for damages on the same issue post-close. A double dip.

Most M&A agreements are governed by Delaware law, and Delaware is a pro-sandbagging jurisdiction. Under Delaware law, unless the contract explicitly states otherwise, a buyer can legally sue for breaches they knew about prior to closing. The legal rationale is that warranties are bargained-for contractual rights regardless of knowledge.

The defensive clause: an affirmative anti-sandbagging provision containing a knowledge waiver. The buyer waives any right to indemnification for breaches of representations they (or their agents) had actual knowledge of prior to closing. Negotiations typically focus on the definition of "knowledge." Sellers prefer "constructive knowledge" — what the buyer should have known from due diligence. Buyers negotiate for the narrower "actual knowledge" — what they explicitly knew. The seller's position is stronger when supported by comprehensive disclosure schedules, which shift risk by putting all known issues on the record before closing.

§ 04 · Three priority checks for any APA reviewWhat to flag before signing.

For sellers in the deal-flow stage with any deferred component — seller note, earnout, rollover — three priority checks should run before APA signing.

Check 1 — Set-off limitations. Is set-off restricted to undisputed claims? Is there an arbitration requirement for disputed claims? Does the contract route disputed amounts to a neutral escrow rather than letting the buyer retain them?

Check 2 — Cross-default inclusion. Is there a cross-default clause linking the seller note to the senior debt? Does it include acceleration rights? Does it preserve the seller's creditor standing in workout or bankruptcy proceedings?

Check 3 — Anti-sandbagging language. Especially for Delaware-governed deals, is the knowledge waiver explicit? Is the definition of "knowledge" negotiated in the seller's favor (or at least balanced)? Are the disclosure schedules comprehensive enough to back up the waiver?
