TL;DR: If a contractor or freelancer you paid to build something, code, a design, a product feature, is now using that same work to compete with you or sell it elsewhere, what you can actually do depends heavily on whether your contract included a proper, specific IP assignment clause. Where it did, you likely have a strong breach of contract claim and can move quickly. Where it didn’t, or where the assignment was vague, you may be relying on weaker default rules, and the fix starts with understanding exactly what you actually own before you confront anyone.
Quick overview: This guide covers what to do first, the specific legal remedies available depending on what your contract actually says, and why this situation is so often preventable but rarely prevented. If this hasn’t happened to you yet, our complete IP assignment guide covers exactly the clause that determines whether you’re protected before you’re ever in this position.
Why this happens more often than founders expect
Paying someone to build something creates a natural, reasonable assumption: you paid for it, so you own it. In most legal systems, that assumption is not automatically true. Copyright in code, designs, and creative work generally vests in the person who actually created it, the contractor, not the person who paid for it, unless a written agreement specifically assigns that ownership to you. Our guide on work for hire versus independent contractor agreements covers exactly why this default rule catches so many businesses off guard.
This is precisely why a contractor using your paid-for work to build a competing product, sell it to someone else, or reuse it across multiple clients is not always a clear-cut theft case. Sometimes it is, when a proper assignment clause exists and the contractor is violating it outright. Sometimes it’s murkier, when no clear assignment was ever signed, and the contractor may have a genuine legal argument that they retained rights to their own work all along.
The first thing to do: find out what you actually own
Before you contact the contractor, before you send any angry message, pull the actual signed agreement, if one exists, and read the intellectual property clause specifically, not just skim it. Look for whether it explicitly states that all work product is assigned or transferred to you upon payment, whether it covers the specific type of work in question, code, designs, documentation, and whether it was signed before the work started or only after.
If there is no written agreement at all, or the agreement never addresses IP ownership, your position is considerably weaker, and this needs to be understood honestly before you decide how aggressively to respond. If there is a clear, properly drafted assignment clause and the contractor is violating it, you are in a genuinely strong position, and the next steps below apply directly.
Document everything before you confront anyone
Once you understand what your contract actually says, gather evidence: what the contractor is doing now, where the competing product or reused work is being offered, dates showing your original engagement and payment, and any similarities between what you paid for and what’s now being used elsewhere. Screenshots, product pages, and timestamps matter here, since this evidence is what any subsequent notice, negotiation, or legal action will actually rest on. Don’t tip off the contractor before you’ve gathered what you need, since evidence has a way of disappearing once someone knows they’re being watched.
What you can actually do if your contract has a proper assignment clause
Where a valid IP assignment exists and the contractor is using the work in violation of it, you have real, concrete options, and the strength of your position means you can move with real confidence.
Send a formal cease and desist. A properly drafted notice, referencing the specific contract clause breached and demanding the contractor stop using, selling, or distributing the work immediately, is often the fastest way to resolve this without litigation. Many contractors stop the moment they realise the client has a documented legal basis and is genuinely prepared to act on it, rather than just venting frustration privately. Our cease and desist service covers exactly this kind of enforcement notice.
Pursue a breach of contract claim. Where the cease and desist doesn’t resolve things, a breach of contract claim over the IP assignment clause specifically is generally a stronger, more straightforward legal path than trying to prove copyright infringement from scratch, since you’re enforcing what the contractor explicitly agreed to, not arguing default ownership rules. Our guide on what to do if someone breaches a contract covers the general escalation process this fits into.
Consider an injunction if the harm is ongoing and significant. Where a contractor is actively selling or using your IP to compete with you right now, and the damage is compounding daily, courts in many jurisdictions can grant urgent interim relief ordering the contractor to stop immediately, rather than waiting for a full trial. This is a genuinely serious step, reserved for situations where the ongoing harm is real and provable, and it needs to be pursued quickly, since delay can itself weaken the case for urgent relief.
What your options look like if the assignment was weak or missing
This is a harder conversation, and it deserves an honest answer rather than false reassurance. If there was no proper written assignment, or the clause was vague about what work it actually covered, your legal position is genuinely weaker, and a direct claim to full ownership may not succeed outright.
That doesn’t mean you have no options. If the contractor is using confidential information you shared with them, business strategy, proprietary processes, non-public technical details, a confidentiality obligation may apply independently of IP ownership, particularly if you had the contractor sign an NDA. Our complete NDA guide covers exactly this kind of protection, and it’s worth checking whether one was in place even if the IP assignment itself was weak.
It’s also worth having a direct, documented conversation with the contractor before escalating, since in some cases a negotiated resolution, a retroactive assignment in exchange for a final payment, a licence arrangement, or a clean split, is genuinely faster and cheaper than a legal fight you’re not certain to win outright. A lawyer reviewing your specific documentation can tell you honestly which category your situation falls into before you commit to a strategy.
How to make sure this never happens again
Once this specific situation is resolved, the actual fix is structural, not just a one-time cleanup. Every contractor and freelancer agreement going forward needs an explicit, specific IP assignment clause, stating clearly that all work product created under the engagement is assigned to you upon payment, covering the exact categories of work involved, code, designs, documentation, and signed before work begins, not after. Where the work involves software specifically, our Software Development Agreement template covers exactly this clause, along with the open-source disclosure and warranty provisions that matter just as much. Pairing this with a proper NDA for any engagement involving confidential business information closes the second half of the gap that usually causes this exact situation.
Frequently asked questions
If I paid a contractor to build something, do I automatically own it?
Not automatically, and this is the single most common misunderstanding in this exact situation. In most jurisdictions, copyright in code, designs, or creative work vests in the person who actually created it, not the person who paid for it, unless a written agreement specifically assigns that ownership to you. Payment alone does not transfer ownership.
What should I do first if I discover a contractor is using my paid-for work to compete with me?
Pull the original signed agreement and read the IP assignment clause specifically before contacting the contractor. Document what they’re doing now, with dates, screenshots, and evidence of the reused or competing work, before you confront them, since evidence tends to disappear once someone knows they’re being watched.
Can I send a cease and desist if a contractor is using my IP without a written contract?
It’s harder, but not necessarily impossible, particularly if the contractor is using confidential business information rather than just their own work product, since a separate confidentiality obligation, especially under a signed NDA, can apply independently of who owns the underlying IP. Without either a clear assignment clause or an NDA, your legal position is genuinely weaker, and this should be assessed honestly before deciding how to proceed.
Is it better to negotiate with the contractor or go straight to legal action?
This depends on how strong your documented position is and how much ongoing harm is occurring. Where you have a clear, signed assignment clause being violated, a formal cease and desist from a lawyer is often fast and effective on its own. Where your position is weaker, a direct, documented negotiation is sometimes genuinely the faster and more reliable path to a resolution than litigation with an uncertain outcome.
How can I prevent this from happening with future contractors?
Use a written agreement with an explicit IP assignment clause for every contractor engagement, signed before work begins, specifying exactly which types of work product are covered. Pair it with a non-disclosure agreement covering any confidential business information the contractor will be exposed to. Both documents close the two separate gaps that most commonly lead to exactly this situation.
