Mexico IP Assignment for Contractors: LFDA Requirements

Mexico IP Assignment for Contractors: LFDA Requirements

Mexico's intellectual property framework creates a critical gap for startups that engage Mexican contractors without proper IP assignment agreements. Under the Ley Federal del Derecho de Autor (LFDA), software is protected as a literary and artistic work, and copyright vests automatically in the author upon creation. For independent contractors — who are not employees — the automatic assignment to the employer under Article 84 of the LFDA does not apply. The contractor retains copyright in code they create, absent an explicit written assignment.

This guide covers the IP assignment requirements for Mexican contractor engagements, the specific provisions that a compliant IP assignment must include under Mexican law, the moral rights considerations that affect assignment drafting, and the remediation steps for startups with existing contractor relationships lacking proper IP documentation.

LFDA Framework for Contractor IP

The LFDA distinguishes between obras por encargo (commissioned works) and obras en relación de trabajo (works created in an employment relationship). For an obra por encargo — a work commissioned from an independent contractor — Article 83 of the LFDA provides that the economic rights belong to the person who commissioned the work, provided the commission is documented in writing and the work was created specifically for the commissioning party.

However, Article 83 has significant limitations. First, it applies only to specific categories of works enumerated in the statute — and its application to software commissioned from contractors has been the subject of legal debate. Second, even if Article 83 applies, the contractor retains moral rights (derechos morales) in the work, which cannot be assigned under Mexican law. Third, Article 83 does not automatically cover derivative works or modifications created after the initial commission — these require separate assignment.

Given these limitations, the recommended practice is to include an explicit IP assignment clause in every Mexican contractor agreement, rather than relying on the Article 83 obra por encargo default. The assignment should cover all economic rights (derechos patrimoniales) in works created under the agreement, including source code, documentation, design assets, and derivative works.

Moral Rights Under Mexican Law

Moral rights (derechos morales) in Mexico are perpetual, inalienable, and non-waivable under Articles 19-23 of the LFDA. They include the right of disclosure, the right of attribution, the right of integrity, the right of withdrawal, and the right of modification. Because moral rights cannot be assigned or waived, an IP assignment agreement that purports to transfer moral rights is ineffective to that extent.

In practice, this means that a Mexican contractor always retains the right to have their name associated with their work (right of attribution) and the right to object to modifications that damage their reputation (right of integrity). For commercial software development, these moral rights are managed through contractual commitments: the contractor agrees not to exercise their right of attribution in connection with commercial distributions of the software, and agrees not to object to reasonable modifications made in the normal course of product development.

INDAUTOR Registration

The Instituto Nacional del Derecho de Autor (INDAUTOR) administers copyright registration in Mexico. Registration is voluntary but creates a public record and a rebuttable presumption of authorship. For software with significant commercial value, INDAUTOR registration in the company's name — following a valid IP assignment from the contractor — provides investor-comfort documentation and evidentiary benefits in potential infringement disputes.

The registration process involves submitting the source code (kept confidential), a description of the software, the assignment agreement, and payment of the registration fee. INDAUTOR typically processes registrations within 30-90 days. For startups preparing for Series A fundraising, initiating registration at least three months in advance provides a comfortable buffer.

Drafting a Compliant IP Assignment Clause

A compliant IP assignment clause for Mexican contractor agreements should include the following elements:

• Assignment of economic rights — "Contractor hereby assigns to Company all economic rights (derechos patrimoniales) in and to the Works, including but not limited to the rights of reproduction, distribution, public communication, transformation, and making available to the public, for the full term of copyright protection and throughout the world."
• Scope of works — Define the works being assigned: all software, source code, object code, documentation, designs, interfaces, databases, and derivative works created by the contractor in connection with the services.
• Future works — Include an obligation to assign future works not yet created: "Contractor agrees to execute any additional instruments reasonably requested by Company to perfect the assignment of economic rights in Works created after the date of this Agreement."
• Moral rights management — Include the moral rights management clause described above.
• Warranty of originality — Contractor warrants that the Works are original, do not infringe third-party rights, and do not incorporate third-party materials (including open source) that would restrict the Company's rights.
• Consideration — The assignment must be supported by adequate consideration. In most cases, the service fees payable under the agreement constitute sufficient consideration for the IP assignment.

Retroactive IP Assignments in Mexico

For existing contractor relationships without IP assignment documentation, retroactive assignments are the recommended remediation. Under Mexican law, a retroactive IP assignment agreement is valid provided it: (1) clearly identifies the works being assigned; (2) is in writing and signed by both parties; and (3) includes consideration (acknowledgment of fees already paid is typically sufficient).

The retroactive assignment should be registered with INDAUTOR to create a public record. The registration demonstrates to investors that the IP gap has been identified and remediated, strengthening the company's due diligence position.

Open Source in Contractor-Created Code

A frequent IP complication in contractor-created code is the incorporation of open source components without disclosure. A Mexican contractor who incorporates AGPL v3-licensed code into a commercial product without the company's knowledge creates both a compliance problem (the company may be violating AGPL v3 terms) and a warranty breach (the contractor has not delivered clean IP). The IP warranty clause in the contractor agreement — warranting that the works do not incorporate open source materials that would restrict the company's rights — is the primary protection against this scenario.

International IP Framework for Mexico Assignments

IP assignments executed under Mexican law are internationally effective under the Berne Convention and the TRIPS Agreement framework. Mexico's membership in both treaties means that a properly executed IP assignment under the LFDA transfers rights that are enforceable in all Berne Convention member states — including the US, EU, and all major LATAM markets. For Mexican startups with international investor interest, domestic IP assignments executed in compliance with LFDA requirements provide cross-border protection without requiring separate foreign filings.

The INDAUTOR registration system plays an important role in documenting Mexican IP assignments for international purposes. A registration in the company's name, following a valid LFDA assignment from the contractor, creates a publicly searchable record. US and EU investors conducting cross-border due diligence on Mexican portfolio companies can access INDAUTOR records as part of their verification process — making registration not just a domestic compliance step but an international communication tool for the company's IP ownership.

For Mexican tech companies using open source components, the LFDA's treatment of open source licenses as enforceable copyright licenses has important implications for the IP warranty clause in contractor agreements. A contractor who incorporates GPL v3 or AGPL v3 components without disclosure is breaching the IP warranty and potentially creating LFDA copyright violations for the company. The Open Source Initiative's license catalog and the SPDX license list provide the reference frameworks that should be incorporated by reference into the open source disclosure obligation in contractor agreements — requiring contractors to disclose specifically any components on the SPDX license list that carry copyleft obligations.

Mexico's USMCA (United States-Mexico-Canada Agreement) IP chapter creates enhanced IP enforcement mechanisms for USMCA-member companies. The USMCA requires Mexico to provide criminal sanctions for commercial-scale copyright infringement and effective enforcement of technology protection measures (TPMs). For Mexican startups that incorporate DRM or anti-circumvention measures into their software products, USMCA protections supplement the LFDA framework and provide additional enforcement tools against infringers. The IMPI's enforcement capabilities under the LFPPI are the primary administrative enforcement mechanism for patent and trademark violations, while LFDA copyright enforcement flows through the federal court system. WIPO's arbitration center provides neutral dispute resolution for international IP disputes involving Mexican parties.
