WESIGN DOC eSignature Compliance in Mexico

Legal Framework

Mexico’s electronic signature framework consists of two main pillars:

• Ley de Firma Electrónica Avanzada (LFEA): Governs advanced electronic signatures (FIEL or Firma Electrónica Avanzada), ensuring their legal recognition across public and private sectors.

• Commerce Code (Código de Comercio): Recognizes the use of electronic means for commercial agreements and ensures that contracts executed electronically are enforceable when the parties’ intent and document integrity can be demonstrated.

Under these laws, an electronic signature in Mexico must:

• Be uniquely linked to the signer.

• Allow identification of the signer.

• Be created using means that the signer can maintain under their exclusive control.

• Be linked to the signed data in such a way that any alteration of the document is detectable.

WESIGN DOC’s Compliance Assurance

WESIGN DOC ensures full compliance with the principles of the LFEA and Commerce Code, providing a secure environment for executing electronic agreements that meet Mexico’s legal standards.

Each WESIGN DOC signature:

• Is generated through a qualified digital certificate that meets strict cryptographic and authentication requirements.

• Protects signer identity and ensures data integrity for every transaction.

• Is tamper-evident, making any post-signing changes traceable.

• Can be validated in trusted platforms such as Adobe Acrobat, where the signature’s authenticity and source of trust can be verified.

• Maintains detailed audit trails to provide transparent proof of the signing process.

By adopting a framework that aligns with the technical and legal criteria defined in the LFEA, WESIGN DOC ensures compliance with Mexico’s standards for advanced electronic signatures.
