How can I protect myself from post-closing liabilities after selling a business?
The contract protections that cap what you can owe after a sale, plus the loose ends the purchase agreement does not cover.
By Michael D. Rubin, CEO & Founder · September 2026 · 812 words
You protect yourself mainly in the purchase agreement: cap how much you can ever owe the buyer, set a threshold before any claim can be made, limit how long claims are allowed, make an escrow the buyer’s main source of recovery, and disclose everything you know before you sign. Then tie off the obligations the agreement does not reach, such as personal guarantees, insurance and final taxes.
None of this replaces honest disclosure. The strongest protection is a buyer who knew about every issue before closing and priced it in.
Where post-closing liability comes from
After closing, a buyer can come back to you in a few ways. The main one is indemnification: your contractual promise to repay the buyer for losses caused by a false statement in the purchase agreement or by problems that belong to the period before the sale, such as unpaid taxes or a customer claim over work done on your watch.
Other exposure sits outside the agreement. You may still be personally guaranteeing a bank line, an equipment lease or the building lease. In an asset sale, liabilities the buyer did not assume stay with your old company, which you still own. Employees, tax authorities and former customers can also reach the entity you controlled.
The protections to negotiate, and what each one does
| Protection | What it does | What to push for |
|---|---|---|
| Cap | Limits the total you can owe for most claims | A cap tied to a modest share of the price for general claims, set by your attorney |
| Basket | A threshold of losses the buyer absorbs before claiming | A true deductible, so only losses above the threshold are recoverable |
| Survival period | The window in which claims can be brought | The shortest window the buyer will accept for general promises |
| Escrow or holdback | Part of the price held back to pay valid claims | Escrow as the buyer’s main or only source of recovery, released on schedule |
| Exclusive remedy | The indemnity process is the only route to a claim | No separate lawsuits outside the agreement, except for fraud |
| Representations and warranties insurance | A policy that pays covered breaches instead of you | Worth asking about in larger deals; the buyer usually buys it |
Loose ends the purchase agreement will not tie up
- Personal guarantees. List every loan, credit line, equipment lease and property lease you have signed personally. Require the buyer to replace them at closing or indemnify you until it does.
- Tail insurance. Some policies only cover claims made while the policy is active. Ask your insurance agent whether you need extended coverage for claims that arise after the sale about events before it.
- Final taxes. Agree who prepares and pays the final returns for the period before closing, and set aside funds if your old company owes them.
- Payoffs and lien releases. Get written payoff letters and confirm that liens on company assets are released.
- Employee obligations. Final pay, accrued vacation and benefit plan responsibilities should be assigned clearly.
- Records. Keep copies of the financial and legal records you will need if a question arises years later.
Deal structure shifts where liabilities land
In an asset sale, the buyer takes the assets and chosen contracts, and everything else stays with your entity, which you will wind down with your attorney and CPA. In an ownership sale, the entity and its history pass to the buyer, and the buyer relies on your indemnity for the past. Neither is automatically safer for you. The protections in the table matter in both, and the choice of structure should be made with your advisors before the letter of intent is signed.
The best protection happens before the letter of intent
An issue disclosed early is a price discussion. The same issue discovered after closing is a claim against you. That is why careful sellers bring known problems forward during marketing and diligence rather than hoping they go unnoticed. Our long read on what causes a business sale to fall apart in due diligence lists the issues buyers most often uncover late.
It is also why the highest price is not always the best offer. A slightly lower price with a firm cap, a short survival period and a clean escrow can leave you with more certainty and, often, more money. Our guide on comparing offers treats these terms as part of the price.
What we do in that situation
We work alongside your own transaction attorney and CPA, who draft and advise on the legal and tax terms. Our part is making sure caps, baskets, escrow and survival periods are raised while buyers are still competing, because that is when you have leverage, and presenting each offer to you in person with those terms visible. Legal documents and closing are the last steps of our ten-step process.
