Question
How do I write a non-assignment clause in a contract?
I want to stop my vendor from handing off my project to someone else without my approval.
Answer
You can write a non-assignment clause by clearly stating that the vendor cannot transfer the contract or delegate the work without your prior written consent. This gives you control over who performs the services.
A well-written clause also explains what happens if the vendor tries to assign or delegate without approval.
What should a non-assignment clause include?
A strong clause should clearly restrict both assignment (transferring the contract) and delegation (handing off the work).
It should state that neither rights nor duties can be transferred without your written consent. It can also include language that any unauthorized transfer is void or considered a breach.
This helps ensure the vendor cannot pass the work to someone else without your knowledge.
How does this protect your business?
This type of clause protects your ability to choose who you work with. It ensures the vendor you selected remains responsible for the project unless you approve a change.
It also reduces the risk of lower-quality work or unexpected third parties getting involved without your review.
What to do next...
- Decide if you want to block all assignments or allow them with consent.
- Include clear "no assignment without written consent" language.
- Add terms explaining what happens if the clause is violated.
- Review the clause with your full contract to ensure consistency.
What to consider in your specific situation
While non-assignment clauses are common, your situation may depend on several factors.
- The type of services and how important the vendor's identity is.
- Whether you want flexibility to allow approved transfers.
- The wording used to define assignment and delegation.
- The risk of subcontracting affecting quality or timelines.
- Local laws that may affect enforceability.
- The importance of control over who performs the work.
