Unless you have a written, signed assignment, an independent contractor normally owns the intellectual property they create for you, not your company. That default holds even after you’ve paid every invoice. The fix is straightforward: pause any deployment where title is unclear, get a signed present-tense assignment covering the work already done, and collect the contractor’s W-9 or W-8 form along with repository access logs as proof of ownership.
TL;DR:
Contractors own the IP they create unless a signed, present-tense assignment explicitly transfers ownership, especially in tech work outside narrow statutory categories.
State laws, notably California’s carve-outs and worker classification rules, can invalidate broad IP clauses if not carefully drafted.
Every contractor agreement should include a detailed, signed, irrevocable assignment, pre-existing IP carve-outs, and subcontractor flow-down provisions to ensure enforceability.
Implement a strict onboarding process that verifies signing before granting repository access, collecting tax forms, and confirming IP transfer compliance.
If an IP gap exists, quickly secure a signed retroactive assignment, consider licensing temporarily, and document all communications to facilitate later enforcement or due diligence.
Why “Work Made for Hire” Rarely Covers Remote Contractor IP Assignment
Most hiring managers assume the phrase “work made for hire” in a contract automatically hands them ownership. It usually doesn’t. Under 17 U.S.C. §101, work made for hire status for an independent contractor applies to only nine narrow categories: contributions to a collective work, parts of a motion picture, translations, supplementary works, compilations, instructional texts, tests, answer materials for tests, and atlases. Software, product designs, marketing copy, UI assets, and most SaaS deliverables fall outside every one of them.
That gap matters because a work-for-hire recital without a matching assignment does nothing. Sulle Law’s analysis on independent contractor IP ownership confirms that a separate, explicit written and signed assignment is required to transfer copyright when the deliverable doesn’t fit those statutory categories, which is nearly always the case in tech work.
The practical difference:
- A work-for-hire recital claims the company was always the “author,” which courts reject when the category doesn’t match.
- A present-tense assignment transfers ownership the contractor already holds, regardless of category.
- Only the assignment survives a challenge during due diligence.
Investors and acquirers check this specifically. A missing assignment on a core repository can stall a term sheet for weeks while counsel chases down a contractor who left the project two years ago. If your cap table diligence checklist doesn’t already flag IP assignment gaps, add it before your next raise.

State-Level Traps That Can Invalidate Your Assignment
Federal copyright law sets the floor, but state law decides whether your clause actually holds up. California is the sharpest example. Its invention-assignment carve-outs mean an overly broad clause may not bind a California-based contractor for work built entirely on their own time with their own equipment, unless the clause is drafted narrowly enough to survive that exception, according to Encore Law’s overview of work-for-hire rules.
Worker classification compounds the risk. California regulators have increased scrutiny of contractor relationships that look like employment, and a misclassified “contractor” can trigger insurance and tax liabilities that undercut the assignment itself, per guidance on California worker classification.
A quick reality check: a contract clause that would hold in Texas or Illinois can fail in California if it reads like a blanket claim to “all inventions” without the required carve-out language for independent work.
Other states add their own wrinkles. New York courts tend to enforce broadly worded assignments as written, while Illinois and Texas generally follow contract terms closely but still defer to statutory exceptions where they exist. To tighten enforceability across jurisdictions:
- Add a narrow tailoring clause excluding inventions made entirely outside company time and resources.
- Specify governing law explicitly, but note that mandatory local employee-protection statutes can override a chosen governing law.
- Reconfirm contractor classification annually, not just at signing.
The Clause Checklist Every Contractor Agreement Needs
A clean IP assignment clause isn’t one sentence. It’s a stack of specific provisions, and skipping any one of them creates a hole a buyer’s counsel will find. The FreelanceDesk guide to IP ownership clauses recommends treating this as “belt-and-suspenders” drafting: a work-for-hire recital where it legitimately applies, plus a present-tense assignment that catches everything else.
Here’s what to require in every agreement before a contractor touches a codebase:
- Present-tense, irrevocable assignment covering all work product, present and future, including derivative works. “Will assign” is weaker than “hereby assigns.”
- Pre-existing IP carve-out, typically as Exhibit A, listing tools, libraries, or code the contractor brings in and retains ownership of, with a license granted to you for embedded use.
- Moral rights waiver where the jurisdiction permits it. Creative Commons offers useful reference language on how moral rights and attribution interact with assignment clauses.
- Further-assurances obligation, requiring the contractor to sign additional documents later if a patent filing or acquisition requires it.
- Originality warranty, confirming the work doesn’t infringe a third party’s rights.
- Subcontractor flow-down requirement, binding any subcontractor the contractor engages to the same assignment terms.
- Signature timing rule: signed before work begins, not after delivery.
Turning the Contract Into an Onboarding Process
A signed clause is only as good as the process that surrounds it. Chain-of-title breaks most often at the operational level, not the drafting level, and the fix is a fixed onboarding sequence every remote hire follows without exception.
The recommended order, drawn from contractor onboarding practices for global remote teams, runs like this: confirm classification first, sign the agreement before any work starts, collect the W-9 or W-8 form before the first payment goes out, then hand over repository access only after the assignment is executed.
- Never grant production repo access before the assignment clause is countersigned.
- Require subcontractors and staffing agencies to sign matching assignments; an agency that hasn’t secured IP transfers from its own developers can’t pass clean title to you.
- Use consistent commit naming and contractor email domains tied to the signed agreement, so ownership evidence is traceable during an audit.
- Store signed assignments, tax forms, and access logs in one folder per contractor, not scattered across email threads.
Cross-border hiring adds a layer local counsel should flag early: local labor protections in the contractor’s home country can sometimes override contractual assignment terms, according to practitioner guidance on remote developer IP rights. That’s a reason to work with a partner who already understands tech contractor classification in the hiring country, not just US federal law.
Pro Tip: Screenshot the repository’s commit history and access-grant timestamps the day you finalize an assignment. That single artifact answers most investor diligence questions in one email instead of a week of back-and-forth.
Fixing an IP Assignment You Never Got
If you’re mid-fundraise or mid-acquisition and just discovered a contractor from eighteen months ago never signed anything, don’t panic, but move fast. Paying an invoice never transferred copyright, and buyers know it: Bloomberg Law’s analysis of IP ownership misunderstandings confirms this is one of the most common deal delays in tech M&A.
Work through these in order:
- Reach out for a retroactive signed assignment first. Most contractors sign without friction, especially if the relationship ended amicably. Offer a small fee for the signature if the original contract was ambiguous.
- If the contractor is unresponsive, negotiate a limited exclusive license covering your use case while you keep pursuing a full assignment.
- Escrow the code or asset with a neutral third party if the contractor disputes ownership, buying time without blocking deployment entirely.
- Bring in an IP attorney once negotiation stalls, particularly if the contractor has left the country or is unreachable, since remediation options often depend on jurisdiction-specific enforcement mechanics.
Document every email and signed version along the way. That paper trail is what accelerates a diligence review far more than the final signature alone.
GENTY recruitment’s Practitioner Notes on Clean Contract Hygiene
Sourcing remote engineers without a contract hygiene process baked in is how most IP gaps happen in the first place. Some agencies build classification checks and assignment expectations into the hiring workflow itself, so the clause isn’t an afterthought bolted on after a candidate has already started committing code.
Cost is often the reason companies skip proper legal review on contractor paperwork, and that’s a false economy. Typical monthly fully loaded costs for senior engineers in LATAM countries vary by country and seniority, generally ranging from several thousand dollars a month, with overlapping time zones with US EST/PST. All four sit well below US or Western European senior engineering salaries, and all four operate on time zones overlapping US EST or PST by four to eight hours, so the contract review meeting your legal team needs doesn’t have to happen at midnight for either side.
What to check before a candidate touches production:
- Who signs the assignment: the individual contractor, never just the staffing agency’s master agreement, unless that agreement explicitly flows down IP terms to each developer.
- Whether the candidate previously worked through an agency that may still hold partial rights to reusable code libraries.
- Documentary handover: signed assignment, tax form, and repo access grant, all dated and stored before the first sprint closes.
Red flags worth pausing on: a candidate who can’t produce a prior assignment from a previous employer, a staffing intermediary that won’t confirm its own developers signed IP transfers, or a rushed contract signature after work has already started.
What I Would Do in the Next 72 Hours
If this article made you nervous about a specific contractor relationship, here’s the short version. First, pause any external deployment or investor conversation touching the asset in question until title is clear. Second, get a signed present-tense assignment today, even a one-page version covering past and future work, rather than waiting for a perfect contract. Third, pull the tax form and repository access logs now, before memories fade or the contractor becomes unreachable.
Call your in-house counsel first, or an outside IP attorney if you don’t have one, and ask specifically: “Does this clause survive California’s carve-out rules, and does it cover derivative works?” If the gap involves a LATAM hire sourced through an agency, ask your recruitment partner whether the agency’s own developer agreements include matching assignments. Escalate to counsel immediately if you’re within 90 days of a funding round or acquisition conversation.
