Assignment of Contracts
Assignment of Contracts is a legal and regulatory term relevant to M&A transactions — governing contract rights, regulatory approvals, or post-close obligations.
Full Definition
Assignment of contracts is the legal transfer of rights and obligations under an existing contract from one party (the assignor) to another party (the assignee). In M&A, this typically occurs when a buyer acquires a business through an asset sale and needs to step into the seller's position under customer agreements, supplier contracts, leases, software licenses, and other commercial arrangements.
The assignment problem: Most commercial contracts contain anti-assignment clauses that prohibit the transfer of the contract without the counterparty's prior written consent. This is the central challenge in asset deal M&A: the buyer wants the seller's contracts, but many of those contracts require third-party consent to assign. Missing this step means the buyer takes on the business operations without the underlying contractual rights being validly transferred — creating legal exposure.
Change of control provisions: Some contracts are more restrictive than a standard anti-assignment clause: they include "change of control" provisions that trigger consent requirements or termination rights even in a stock deal, where no legal assignment occurs. A customer contract that says "this agreement terminates if Seller undergoes a change of control" creates risk in both asset and stock acquisitions.
Practical approach: During due diligence, buyers audit all material contracts for assignment restrictions and change of control triggers. The seller then sends consent requests to counterparties (customers, landlords, suppliers) and tracks responses. Some consents are routine and granted quickly; others (government contracts, franchise agreements, regulated licenses) require formal applications and can take months. Contracts where consent is denied or not obtained before closing can either be excluded from the transaction or addressed through a transition services agreement (the seller continues operating the contract temporarily while consents are obtained post-close).
Assumption of liabilities: Assignment transfers rights; the accompanying concept is "assumption of liabilities." In a standard asset purchase, the buyer specifies exactly which contracts — and which obligations under those contracts — it is assuming. Buyers can cherry-pick: they might assign the customer agreement but not assume pre-closing liability for past invoicing errors. The specifics are documented in the Asset Purchase Agreement's schedules.
Seller vs. Buyer Perspective
You are responsible for obtaining assignment consents from your counterparties, but the buyer's cooperation matters too — some customers or suppliers will want to hear from both parties before consenting. Start identifying consent requirements early and send notices well before your planned closing date. Contract counterparties who are slow to respond to consent requests can delay closings by weeks. For any counterparty who might use the assignment request as leverage to renegotiate terms, brief your buyer before reaching out.
The contract assignment audit is one of the most important parts of due diligence in an asset deal. Get a complete list of all material contracts — especially customer agreements, leases, supplier relationships, and software licenses — and confirm the anti-assignment language in each. Prioritize by criticality: a large customer contract that can't be assigned without consent is deal-critical and should be addressed before you're deep into exclusivity. Include a closing condition in the purchase agreement requiring that specified material consents be obtained before closing.
Real-World Example
A government-contracting company sells its business in an asset sale. Its primary contract is a 3-year federal GSA schedule agreement representing 60% of revenue. Federal government contracts require a novation agreement — a formal trilateral agreement among the seller, buyer, and the relevant federal agency — to validly assign. The novation process takes 4 months. The parties close the acquisition with a transition services arrangement in place, with the seller temporarily continuing to operate and bill under the contract while the novation is processed.
Why It Matters & Common Pitfalls
- !Missing a change-of-control clause in a stock deal. Even in stock acquisitions, counterparties may have change-of-control termination rights. These don't appear in standard assignment clause analysis — they require a separate review of the entire contract. A missed change-of-control clause in a key customer agreement can unwind significant deal value post-close.
- !Consent requests tip off customers. Sending consent requests to customers effectively announces the sale before you're ready. Plan your communication strategy carefully — in some cases, you may want to close a transaction and obtain consent simultaneously rather than giving customers advance notice that creates relationship risk.
- !Consent doesn't mean the counterparty won't renegotiate. Some customers or landlords treat assignment consent as leverage to improve their terms. Anticipate this and negotiate the consent process carefully. Buyers should know which counterparties present renegotiation risk before the seller sends notices.
- !Assumed contracts come with all their terms, not just the favorable parts. When you assume a contract, you assume every obligation in it — including indemnification obligations, most-favored-nation pricing commitments, and audit rights. Review material assumed contracts fully, not just their anti-assignment clauses.
