Every Contract You've Ever Signed Is About to Be Scrutinized. Here's What That Means.

When a founder decides to sell their business, the conversation usually centers on valuation, deal structure, and what life looks like on the other side. What does not get enough attention — until a buyer's diligence team starts asking questions — is the contracts. Every customer agreement, vendor arrangement, lease, software license, employment contract, and loan document the company has ever signed becomes relevant the moment a transaction is on the table.

Some of those contracts transfer cleanly to a buyer. Others require consent from the other party before they can be assigned. Some contain provisions that are triggered by a change in ownership — and not always in ways that benefit the seller. A few may be problematic enough to affect the deal price or the deal itself.

Understanding what happens to your contracts in a business sale is not a detail to sort out during due diligence. It is preparation that needs to happen well before a buyer is in the room.

Asset Sale vs. Stock Sale: The Threshold Question

How your contracts are treated in a sale depends largely on whether the transaction is structured as an asset sale or a stock sale. The distinction matters enormously.

In a stock sale, the buyer acquires the legal entity itself. The company — and all of its contracts — continues to exist under new ownership. Because the contracting party has not changed, most contracts transfer automatically without requiring consent from the other party.

In an asset sale, the buyer acquires specific assets of the business rather than the entity. Contracts are assets — and like other assets, they need to be assigned from the seller to the buyer. Many contracts contain anti-assignment clauses that either prohibit assignment outright or require the other party's consent before the contract can transfer. Without that consent, the contract cannot be assigned, and the buyer does not acquire it.

For a business whose value is tied to its customer relationships, vendor arrangements, or key licenses, the distinction between these two scenarios can be significant. A buyer who discovers during diligence that a critical customer contract cannot be assigned without consent — and that consent is not guaranteed — will factor that uncertainty into the offer.

Change-of-Control Provisions: The Clause You May Have Forgotten About

Even in a stock sale — where contracts generally transfer automatically — change-of-control provisions can create complications. A change-of-control clause gives the other party the right to terminate or renegotiate the contract if ownership of the company changes hands. These clauses appear in customer agreements, supplier contracts, financing arrangements, software licenses, and commercial leases.

A founder selling their business may not remember signing a contract five years ago that contains a change-of-control provision. The buyer's diligence team will find it. When they do, the question becomes whether that counterparty — a key customer, a critical vendor, a lender — will exercise their rights. The answer affects the value of the business and the terms of the deal.

Identifying those provisions before a buyer finds them gives the seller the opportunity to address them proactively — to seek consent, to renegotiate terms, or to disclose the risk on their own terms rather than having it surface as a diligence finding.

The Contracts That Create the Most Problems

Certain categories of contracts consistently generate issues in business sale transactions.

Customer contracts

If your revenue is concentrated in a small number of customer relationships, those contracts are among the most valuable assets in the deal. Buyers will scrutinize their term lengths, renewal provisions, termination rights, and whether they can be assigned or are subject to change-of-control clauses. A customer contract that can be terminated by the customer upon a change of ownership — particularly a contract representing a significant portion of revenue — is a material issue in any transaction.

Commercial leases

Commercial leases almost universally require landlord consent for assignment. In an asset sale, the buyer needs the lease assigned to them. In a stock sale, the lease may contain a change-of-control provision that triggers the landlord's rights. Either way, the landlord becomes a party whose cooperation the seller needs — and that conversation goes better when it is initiated by the seller before closing, not discovered by the buyer during diligence.

Financing and loan agreements

Loan agreements frequently contain provisions that are triggered by a change of ownership, including acceleration clauses that make the entire outstanding balance due upon a sale. If the company has outstanding debt, the terms of that debt need to be reviewed before a transaction is structured, and the buyer needs to understand what obligations will be satisfied at closing.

Software licenses and IP agreements

Enterprise software licenses are frequently non-transferable without the licensor's consent, and many contain explicit change-of-control restrictions. If the business relies on licensed technology that cannot be assigned or transferred to the buyer, that gap needs to be addressed — through consent, renegotiation, or disclosure — before it becomes a closing condition.

What to Do Before the Buyer Starts Asking

The founders who navigate this part of a transaction most effectively are the ones who have already done their own contract review before a buyer is involved. A pre-sale legal audit — a systematic review of the company's material contracts for assignment restrictions, change-of-control provisions, termination rights, and other deal-relevant terms — puts the seller in control of the narrative. You know what you have. You know what needs attention. You have time to fix it.

Sellers who skip that step find themselves responding to a buyer's diligence findings under time pressure, with less leverage and fewer options. The contracts were always going to be scrutinized. The only question is whether the seller is prepared when that happens.
