Firma digital

Hi @Edgarus,

Hope you are doing well. Thanks for writing in!

To answer your question:

Yes, a digital signature with IP, date/time, XML validation, and a NOM-151 conservation certificate can meet the legal validity requirements in Mexico if the underlying signature uses a certificate from an accredited CSP, the timestamp is trusted, and the proof of conservation is properly implemented and preserved.

However, having those features alone isn’t always enough; you must also ensure identity verification, certificate validity, evidence preservation, and satisfaction of all technical and procedural rules under NOM-151 and related Mexican electronic signature laws.

This page below gives an overview of how Mexican law treats electronic signatures, including distinguishing “electronic signatures” vs “advanced electronic signatures.” It’s a good place to cite for what legal status Adobe assigns to eSignature in Mexico: https://adobe.ly/3Vw85ib

Hope this helps.
