One of the most consequential clauses in any UK freelance contract is the intellectual property assignment. Unlike employees, freelancers own the copyright in work they create by default — it does not automatically pass to the client. But many freelance contracts include broad IP assignment clauses that transfer ownership of far more than clients actually need, including your pre-existing materials, tools, and future derivative works.
What is a IP Ownership?
Under the Copyright, Designs and Patents Act 1988 (CDPA), the default rule is that the creator of a work owns the copyright. For employees, works created in the course of employment belong to the employer. For freelancers and independent contractors, copyright belongs to the freelancer unless there is a written assignment. Most client contracts include IP assignment clauses attempting to transfer copyright in all deliverables. The question is how broadly those clauses are drafted and whether they capture more than was intended.
Red flags to watch for
A clause assigning all IP 'arising from or in connection with this agreement' can sweep up background IP (your pre-existing tools, frameworks, methodologies) that you never intended to give the client.
UK copyright law does not permit moral rights to be assigned — only waived. A clause purporting to assign moral rights is void, but a waiver of moral rights (including the right to be identified as author) is enforceable and significant.
Many contracts state IP transfers 'upon creation' rather than 'upon full payment.' This means the client gets your work even if they never pay you — removing your most important leverage.
Once IP is assigned, you technically cannot show the work in your portfolio without the client's permission. A sensible contract includes a licence-back for self-promotion purposes.
The US 'work for hire' doctrine does not apply in the UK — it has no legal effect here. However, it may indicate a client using a US-template contract that hasn't been adapted for UK law, creating other ambiguities.
Your legal rights
Under the CDPA 1988, copyright in original literary, artistic, dramatic, and musical works vests in the author at creation. An IP assignment must be in writing and signed by the assignor to transfer copyright (section 90 CDPA). You retain moral rights unless you explicitly waive them in writing. If a contract attempts to capture your background IP without adequate consideration or licence-back, you may be able to challenge it as an unreasonable restraint. If you are a sole trader, your personal tax position on IP transactions may also be relevant.
Questions to ask before you sign
- 1Does the IP assignment clause cover only the specific deliverables agreed, or all work created in connection with the project?
- 2Does it capture my background IP — pre-existing tools, frameworks, or code libraries I bring to the project?
- 3When does IP transfer — upon creation, upon delivery, or upon full payment?
- 4Am I being asked to waive moral rights, and if so, do I understand what I'm giving up?
- 5Is there a licence-back allowing me to use the work in my portfolio?
