IP Assignment Clause for Freelancers Explained

An IP assignment clause is one of the most common and most consequential clauses in a freelance contract. It determines who owns the work you create — and in many standard contracts, the answer is the client, not you.

Key takeaway: An IP assignment clause transfers your intellectual property rights from you to the client. Once you sign a contract with an IP assignment clause, the work you create under that agreement legally belongs to the client. The risk comes when clauses are written too broadly — covering work beyond the agreed deliverables, including pre-existing tools, or applying even when the client hasn't paid.

What IP Assignment Actually Means

When you create something — a design, a piece of writing, a software module — copyright attaches to it automatically. As a freelancer, that copyright belongs to you. An IP assignment clause changes that. It's a contractual agreement where you transfer your ownership rights to the client. After a valid assignment, the client owns the work as if they created it themselves.

In many client relationships, this is entirely reasonable. A client who commissions a logo expects to own it. The problem is when the language is broader than the work actually commissioned.

Understanding the difference between IP assignment and work for hire is important — both transfer ownership, but they do so in fundamentally different ways.

The Dangerous Versions

Overly broad scope

“The Contractor assigns to the Client all work product and materials created by the Contractor in connection with or arising out of the Services.”

The phrases ‘in connection with’ and ‘arising out of’ could cover preliminary drafts, ideas developed during the engagement, and potentially personal projects done during the same period.

No carve-out for pre-existing work

Without an explicit carve-out, a client could argue the clause covers tools, libraries, and templates you brought into the project. If your entire workflow depends on code or design systems you've built over years, this is significant exposure.

Assignment effective on signing, not on payment

Some contracts make the assignment effective immediately — upon signing or delivery of drafts — rather than upon final payment. If the client doesn't pay, they may still have a legal claim to your work.

Protecting Your Pre-Existing Work

Ask for a carve-out clause. Something like:

“Notwithstanding the above, the Contractor retains all rights to pre-existing intellectual property, tools, frameworks, and methodologies developed prior to the commencement of this Agreement. The Client is granted a non-exclusive licence to use Pre-Existing IP solely to the extent incorporated into the Deliverables.”

FAQ

Can I use work I created for a client in my portfolio?

Only if the contract explicitly gives you portfolio rights. Without that provision, using client work in your portfolio could technically infringe their IP rights under a full assignment clause.

Is an IP assignment clause enforceable without a signature?

No. An IP assignment must be in writing and signed to be legally valid in most jurisdictions. A verbal agreement or unsigned contract does not effectively transfer copyright.
