Quick Summary
Whether a contract survives a business sale comes down to two legal mechanisms: assignment, which transfers a contract’s benefit but can leave the seller secondarily liable, and novation, which fully substitutes the buyer and releases the seller, but requires the other party’s consent. In a stock sale, the entity itself continues and most contracts stay in place untouched; in an asset sale, each contract has to be assigned or novated individually. Anti-assignment and change-of-control clauses, third-party consent, and outstanding debt all follow the same structure-first logic, and Arizona’s UCC (A.R.S. § 47-2210) governs assignability for contracts involving goods.
Selling a business raises an immediate question: do your existing contracts come with it? The answer depends on two things, how the deal is structured (asset sale or stock sale) and which legal mechanism moves the contract, assignment or novation. Customer and supplier agreements, leases, and intellectual property licenses can all be affected differently depending on their own assignment and change-of-control language.
This guide walks through that framework, what Arizona law says about assignability, and the practical steps buyers and sellers take to identify, transfer, or replace contracts before closing.
Assignment vs. Novation: The Distinction That Decides What Happens to Your Contracts
Nearly every question about what happens to a contract in a business sale comes back to one of two legal mechanisms: assignment or novation, and the difference between them matters far more than most sellers realize.
Assignment transfers a party’s rights (and, if the contract allows, its duties) to the buyer. The original party, the seller, typically remains secondarily liable unless the other party agrees to let them off the hook; the counterparty can usually still come after the seller if the buyer fails to perform. Most contracts can be assigned with notice alone, unless the contract itself says otherwise.
Novation replaces the seller with the buyer entirely. It extinguishes the seller’s obligations under the original contract and substitutes a new party in their place, but it only works if all three parties, seller, buyer, and the original counterparty, agree and sign. A novation agreement is the only mechanism that fully releases a seller from future liability under that contract.
Which one applies, or is even possible, depends on the contract’s own language and the structure of the sale.
Asset Sale vs. Stock Sale: How Deal Structure Changes Contract Transfer
Deal structure decides whether you’re dealing with assignment and novation at all.
In a stock (or equity) sale, the buyer acquires ownership of the company itself. Because the legal contracting party doesn’t change, most contracts simply continue in place, untouched and without any assignment or novation required. The catch is that a change-of-control provision, separate from an assignment clause, can still be triggered purely by the change in ownership, even though the contract technically never moved.
In an asset sale, the buyer acquires specific assets and contracts rather than the company entity. Every material contract the buyer wants has to be individually assigned or novated, since the original contracting entity is staying with the seller. This is why asset sales typically require far more contract-by-contract review during due diligence than stock sales do.
Anti-Assignment Clauses: How to Spot One Before You Sign
An anti-assignment clause is contract language that restricts or prohibits a party from transferring its rights or obligations without the other party’s consent. Some prohibit assignment outright; others allow it only with written notice or prior approval.
To find one, don’t rely on a contract’s table of contents. Search the full text for the words “assign,” “assignment,” “transfer,” and “change of control,” since these clauses are often buried in a general “Miscellaneous” or “General Provisions” section near the end of the agreement, not grouped with the operative terms.
For contracts involving the sale of goods, Arizona’s enactment of the Uniform Commercial Code, A.R.S. § 47-2210, governs how assignment and delegation work by default, including how an anti-assignment clause gets interpreted. Service contracts, leases, and other non-UCC agreements fall back on Arizona common contract law instead, which generally enforces a clear anti-assignment clause as written.
Change-of-Control Provisions
A change-of-control provision is a separate mechanism from an assignment clause, and the distinction trips up a lot of sellers in stock sales specifically. Rather than restricting assignment of the contract itself, it treats a change in who owns or controls the business as a triggering event on its own, one that can require notice, consent, a renegotiation, or even give the counterparty a right to terminate.
This matters most in a stock sale, where the contract never technically moves but ownership still changes hands. A supplier or landlord agreement with a change-of-control clause can be triggered even when no assignment occurs at all.
Third-Party Consent: Who Has to Sign, and What Happens If They Refuse
Whoever holds the other side of a contract, the landlord, the supplier, the customer, the licensor, is the party whose consent you need whenever an assignment clause requires it or a novation is being used. Identify these counterparties during due diligence, not after a letter of intent is signed, since some consents take weeks to obtain.
If a counterparty refuses, the deal doesn’t automatically fall apart. The buyer and seller typically have three options: renegotiate the relationship directly with the buyer as a new counterparty, carve that specific contract out of the sale and let it wind down separately, or price the lost value into the purchase price and move forward without it. In practice, renegotiating directly with the buyer is the most common resolution, since most counterparties would rather keep the business relationship than lose it.
What Happens to Outstanding Business Debt When a Contract Transfers
Debt follows the same structure-first logic as contracts, but the default outcome runs in the opposite direction.
In a stock sale, the buyer acquires the company as-is, debts included, since the legal entity and all of its obligations continue unchanged. Purchase price is typically adjusted to account for the debt the buyer is inheriting, often through a net-debt or cash-free, debt-free structure negotiated into the purchase agreement.
In an asset sale, the buyer generally does not assume the seller’s existing debt unless the purchase agreement specifically says so. The seller is expected to satisfy or pay off outstanding loans, often from the sale proceeds at closing, and lenders holding a security interest in the assets being sold will usually need to release their lien before the sale can close.
Types of Contracts Affected by a Business Sale
- Customer and supplier agreements: often long-term, and the buyer needs to know whether they’re assignable and whether consent is required.
- Employee agreements: non-competes, non-disclosure terms, and other obligations can survive a sale differently depending on deal structure; see our full guide on what happens to existing employees when a business is sold.
- Lease agreements: commercial leases almost always restrict assignment without landlord consent.
- Intellectual property agreements: patents, trademarks, and copyright licenses often need their own review to determine what rights transfer.
Identifying which category each contract falls into is the first step in determining how the sale will affect it.
How to Transfer Contracts: A Step-by-Step Process
- Inventory every material contract: customer, supplier, lease, licensing, and employment agreements, and flag each one’s assignment, novation, and change-of-control language.
- Classify each contract: determine whether it stays with the entity (stock sale), needs assignment, requires novation, or has to be replaced entirely.
- Complete the required documentation: an assignment typically needs written notice or consent; a novation needs a signed agreement from all three parties. For more on drafting the purchase agreement itself, see how to write a contract for selling a business.
- Confirm and notify: verify all required consents are in hand, then notify landlords, suppliers, customers, and employees as each agreement requires.
- Document the final status: keep records of every assignment, novation, consent, or replacement agreement for the closing file.
Starting this process during due diligence, rather than after a letter of intent, keeps consent delays from holding up closing.
What Happens if a Contract Cannot Be Transferred?
When a counterparty won’t consent and the contract can’t be assigned or novated, buyers and sellers generally have three paths forward: terminate the agreement according to its terms and replace it with a new one, negotiate entirely new terms directly between the buyer and the counterparty, or let it continue under the existing entity if the transaction structure doesn’t require assignment in the first place.
Identifying these contracts early lets both sides evaluate the operational and financial impact before it becomes a closing-day surprise.
The Role of a Business Broker in Managing Contracts During a Sale
A business broker helps identify contract issues early, before they become closing-day obstacles. They organize the relevant agreements, flag which ones need consent or novation, and coordinate communication between buyer, seller, landlords, suppliers, and other counterparties as the deal moves forward.
Legal counsel still handles the actual drafting and legal interpretation, but a broker keeps contract-related items on the transaction timeline.

Frequently Asked Questions
Are business contracts automatically transferred when a business is sold?
No, not automatically, and whether they transfer at all depends entirely on deal structure. In a stock sale, the company itself is what’s being sold, so the legal entity that signed each contract never changes, and most agreements simply continue in place untouched. In an asset sale, the buyer is acquiring specific assets and contracts rather than the entity, so each contract has to be individually assigned or novated, and some may require the other party’s consent before they transfer at all.
What is the difference between assignment and novation?
Assignment transfers the benefit of a contract to the buyer, but it doesn’t necessarily let the seller off the hook; unless the other party agrees otherwise, the seller can remain secondarily liable if the buyer fails to perform. Novation is different: it fully replaces the seller with the buyer in the contract and requires all three parties, seller, buyer, and the original counterparty, to sign. Only novation actually releases the seller from future liability under that agreement; a straightforward assignment, even with notice, typically does not.
What is an anti-assignment clause and how do I find one?
An anti-assignment clause is language in a contract that restricts or prohibits transferring the agreement, or rights under it, without the other party’s consent. To find one, search the full text of each contract for the words “assign,” “assignment,” “transfer,” and “change of control,” rather than skimming the headings. These clauses are usually tucked into the “Miscellaneous” or “General Provisions” section near the end of the document, not grouped with the main operative terms where you’d expect to find them.
What happens if a customer or supplier refuses to consent to the transfer?
The deal doesn’t automatically fall apart, but you do have a decision to make. There are generally three paths: renegotiate the relationship directly between the buyer and the counterparty under a fresh agreement, carve that specific contract out of the sale and let it wind down with the seller, or accept the loss and price it into the purchase price through a lower valuation or adjusted terms. In practice, renegotiating a new agreement directly with the buyer is the most common outcome, since most customers and suppliers would rather keep the business relationship than walk away from it.
Do employment contracts transfer when a business is sold?
It depends on deal structure and the terms of each agreement, non-competes, non-disclosure terms, and other obligations can all carry over differently. Because employee contracts raise their own set of legal and practical issues, we cover them in full in what happens to existing employees when a business is sold.
What happens to a commercial lease when a business is sold?
Almost every commercial lease restricts assignment without the landlord’s written consent, and getting that consent is frequently the longest pole in the deal, sometimes longer than negotiating the purchase agreement. Most commercial leases require 30 to 60 days’ advance notice before the landlord will even review an assignment request, and some landlords use the request as leverage to renegotiate rent or other lease terms. Start the landlord conversation as early as possible, ideally the moment the lease is identified during due diligence, not after a letter of intent is signed.
What happens to outstanding business debt when the business is sold?
Treatment depends on deal structure, and the default runs opposite to how contracts usually work. In a stock sale, the buyer acquires the company as-is, debt included, since the legal entity and all of its obligations continue unchanged; the purchase price is typically adjusted downward to account for the debt being inherited, often through a cash-free, debt-free structure negotiated into the purchase agreement. In an asset sale, the buyer generally does not assume the seller’s existing debt unless the purchase agreement specifically says otherwise; the seller is expected to pay off outstanding loans, often from the sale proceeds at closing, and any lender holding a security interest in the assets being sold will typically need to release its lien before the transaction can close.
