3D Artist Freelance Contract UK | 3D Modelling and Rendering Agreement
When you work as a freelance 3D artist in the UK, disputes over asset ownership, revision scope, and late payment can quickly erode the value of a project. Without a written agreement, clients may claim ownership of renders before final payment, demand unlimited revisions, or challenge your self-employed status under IR35 rules set out in Chapter 10 of the Income Tax (Earnings and Pensions) Act 2003. A properly drafted 3D artist freelance contract sets clear boundaries around deliverables, intellectual property transfer, and payment terms enforceable under the Late Payment of Commercial Debts Act 1998. It also documents the working relationship in a way that supports an outside-IR35 determination. Whether you produce character models, architectural visualisations, or product renders, generate your contract now and protect every project from the outset.

Key clauses in a Freelance Contract
Intellectual Property Assignment
This clause defines exactly when and how copyright in the 3D models, renders, and associated source files transfers from the artist to the client, typically upon receipt of full payment. Under the Copyright, Designs and Patents Act 1988, copyright in original artistic works is owned by the creator by default, so an explicit written assignment is required for the client to hold full legal title.
Deliverables and Revision Scope
This clause specifies precisely what files will be delivered, in which formats, and how many rounds of revisions are included within the agreed fee. Without this, clients can request unlimited changes and the contract becomes open-ended, making it difficult to invoice additional work or demonstrate a fixed-term engagement for IR35 purposes under Chapter 10 ITEPA 2003.
Payment Terms and Late Fees
This clause sets the invoice schedule, payment due dates, and the statutory interest rate that applies to overdue invoices under the Late Payment of Commercial Debts Act 1998, currently 8% above the Bank of England base rate. Including this clause means you can claim interest and reasonable debt recovery costs automatically if a business client pays late, without needing a separate court order.

Who owns the 3D models and renders once I deliver them to a client?
Under the Copyright, Designs and Patents Act 1988, you own the copyright in any original 3D artwork you create as a freelancer unless you assign it in writing. Ownership only transfers to the client when your contract explicitly says so, and most well-drafted agreements tie that transfer to full payment being received. Without a written assignment clause, the client has no automatic right to use or modify the files commercially.
Does a freelance 3D artist contract help with IR35?
Yes, a well-structured contract is one of the key pieces of evidence used to assess IR35 status under Chapter 10 of the Income Tax (Earnings and Pensions) Act 2003. Clauses that demonstrate a right of substitution, a defined project scope with a clear end date, and no obligation to accept further work all point toward a genuine business-to-business relationship rather than disguised employment. HMRC's Check Employment Status for Tax tool also considers the written terms of the engagement alongside actual working practices.
Can I charge a client interest if they pay my invoice late?
Yes, if your client is a business, you are entitled to claim statutory interest at 8% above the Bank of England base rate under the Late Payment of Commercial Debts Act 1998 from the day after the payment due date. You can also claim a fixed debt recovery charge between £40 and £100 depending on the invoice value, plus reasonable recovery costs if you use a debt collection service. Your contract should state the payment due date clearly so the calculation start date is not in dispute.
