We are structured as a C Corporation and planning a stock sale using a Section 453 installment note to defer taxes, but we are terrified the buyer will try to offset their post-closing indemnification claims directly against our scheduled note payments. How do we structure the purchase agreement to prevent unilateral offsets without killing the deal?

If you sell your stock via an installment sale under Section 453, you must protect your deferred payments from being hijacked by post-closing indemnity claims. Buyers love to insert right-of-offset clauses in the purchase agreement, allowing them to unilaterally deduct alleged damages from your scheduled note payments. This effectively makes the buyer the judge, jury, and executioner of their own claims. To prevent this, you must negotiate a strict limitation on their offset rights. First, require that the buyer cannot withhold any note payments unless a claim has been formally adjudicated by a third-party arbitrator or agreed upon in writing by both parties. Second, demand that any disputed amounts must be paid into an independent escrow account rather than kept in the buyer's bank account. This forces the buyer to think twice before making frivolous claims because they still have to part with the cash. Bring this issue to your leadership team during your weekly Level 10 Meeting to make sure your legal counsel is aligned. Your V/TO should outline a clean exit, and leaving your deferred proceeds vulnerable to unilateral clawbacks violates that plan. Insist on a reciprocal provision where if they default on the note without a verified claim, the entire outstanding balance accelerates immediately and interest rates spike to the maximum legal limit. This protects your hard-earned equity.
