Is It Legal to Sign Documents with an Electronic Signature in Mexico?

Electronic signatures have become essential for digital business worldwide—and Mexico is no exception. If your U.S. company operates in Mexico, it’s crucial to understand why and how e-signatures are legally valid for labor and commercial documents.

In this blog, we’ll explain Mexico’s legal framework for electronic signatures and how platforms like Sora help you stay compliant while digitizing your HR processes.

📜 Legal Framework for E-Signatures in Mexico

✅ 1. Advanced Electronic Signature Law (LFEA)

This law recognizes that an advanced electronic signature (FIEL) has the same legal validity as a handwritten one—as long as it’s generated through a digital certificate issued by a government-accredited certification authority (CA).

✅ 2. Certification Providers Regulation

Only certified providers (PSC) can issue the digital certificates used for advanced e-signatures. These providers must meet strict standards for security, encryption, and identity verification.

✅ 3. Federal Labor Law (Article 776)

Mexico’s labor law clearly states that digital documents and e-signatures are admissible in court, provided they comply with proper standards. This gives your signed contracts and payroll receipts full legal weight in case of litigation.

✅ 4. Mexican Commercial Code (Articles 89 & 97)

Defines what constitutes an electronic signature and outlines the four legal elements required for it to be considered reliable and enforceable.

✅ 5. NOM-151 Standard

Establishes requirements for digital timestamping and data conservation, ensuring the authenticity and non-repudiation of electronically signed documents.

✅ 6. Federal Fiscal Code

Requires tax documents to be digitally signed using a valid e-signature certificate, reinforcing the importance of proper compliance.

🌐 International Legal Basis

Sora’s digital signature process is based on the UNCITRAL Model Law on Electronic Signatures (by the United Nations). This framework allows countries like Mexico to give legal certainty to electronic documents—aligning with international standards.
