The common versions of this clause
Outright prohibition
Neither party may assign the contract to anyone else without the other's written consent.
Consent required
Assignment is allowed but only with the other party's approval, sometimes with a standard that consent "shall not be unreasonably withheld."
Automatic exception for a business sale
Many clauses specifically allow assignment in connection with a merger, acquisition, or sale of substantially all of a company's assets, without needing separate consent.
Why this matters more than it looks
If you hired a specific freelancer or vendor because of their particular skill or reputation, an unrestricted assignment clause could let them hand your project to someone else entirely, or let a company that acquires your vendor inherit the contract with different priorities.
On the flip side, if you want the flexibility to sell your business or bring in a subcontractor, an overly restrictive assignment clause can block that without the other party's cooperation.
The part most guides skip: subcontracting and assignment aren’t always the same thingSome contracts distinguish between "assignment" (transferring the whole contract) and simply subcontracting part of the work while still remaining responsible for it. A clause that blocks assignment doesn’t necessarily block subcontracting, and vice versa — worth checking which one is actually restricted if flexibility on either front matters to you.
Questions to ask before you sign
- Can either party assign this contract without the other's consent?
- Is there an automatic exception for a merger, acquisition, or business sale?
- Does the clause distinguish between full assignment and subcontracting part of the work?
- If consent is required, does the clause say it can't be unreasonably withheld?
- What happens to the contract if one party is acquired by a competitor?
