What Is an Assignment Clause?

An assignment clause determines whether either party can transfer their contractual rights and obligations to a third party without the other party's consent. Without a restriction, most state laws permit assignment freely; with an anti-assignment clause, a party must obtain written consent before transferring the contract. For freelancers, the assignment clause matters most in M&A scenarios — if a client is acquired and the acquiring company can assume your contract without your consent, you may suddenly owe deliverables to a company you never agreed to work with. According to the American Bar Association, assignment provisions are among the most frequently overlooked boilerplate clauses in commercial service agreements.

Definition

Assignment clauses come in two varieties: those that restrict assignment (anti-assignment clauses) and those that expressly permit it. Most client-drafted contracts include an anti-assignment clause for the service provider — you cannot subcontract or transfer your obligations without approval — while permitting the client to assign freely in connection with a merger, acquisition, or corporate restructuring.

This asymmetry matters. You hired yourself out to work with a specific company — their culture, their team, their project vision. If they're acquired by a competitor you would never have agreed to serve, a one-sided assignment clause means you're still bound. Meanwhile, that competitor is also now the party who owes you payment under the contract, and you have no say in the change.

The best assignment clauses are mutual: neither party can assign without the other's written consent, with a possible carve-out for assignment to affiliates or in connection with a sale of substantially all of a party's assets — and even then, with the assigning party remaining liable.

Sample Assignment Clause Language

"Assignment. Neither party may assign, transfer, or delegate any of its rights or obligations under this Agreement without the prior written consent of the other party, which consent shall not be unreasonably withheld. Notwithstanding the foregoing, either party may assign this Agreement without consent in connection with a merger, acquisition, or sale of substantially all of its assets, provided that: (i) the assigning party provides written notice to the other party at least ten (10) days prior to such assignment; and (ii) the assignee assumes all of the assigning party's obligations under this Agreement in writing. Any purported assignment in violation of this section shall be void."

Frequently Asked Questions

What is an assignment clause in a contract?
An assignment clause determines whether either party can transfer their contract rights and obligations to a third party without the other party's consent. Without a restriction, most state laws permit free assignment. For freelancers, it matters most in M&A scenarios where a client is acquired and the acquirer assumes the contract without your agreement.
Can a company assign a contract without my consent?
Under most state laws, contract rights are generally assignable without consent unless the contract restricts it or the obligation is personal in nature. An explicit anti-assignment clause changes this default. The safest approach is to include mutual anti-assignment language requiring written consent from both parties before any transfer.
What happens to my contract if the client company is acquired?
If the contract contains no anti-assignment clause, a merger or acquisition can transfer your contract to the acquirer without your consent. Many anti-assignment clauses include M&A carve-outs that permit this even with a restriction clause. Check specifically whether M&A is excluded from the restriction in your contract.
Can I assign my freelance contract to a subcontractor?
Only if the contract permits it. Personal services contracts are generally not assignable by the service provider. If you want to subcontract, check whether the contract permits subcontracting separately — it's a distinct right from assignment — and whether client approval is required for specific subcontractors.
What is the difference between assignment and novation?
Assignment transfers rights to a third party, but the original party often remains liable. Novation completely substitutes a new party — the original is released from all obligations. Novation requires all three parties' consent. If your client is acquired and wants to fully exit the contract, a novation — not just assignment — is what actually releases them.
