E-signature legality · Americas
Is electronic signature legal in Mexico?
Yes. Commercial acts may be agreed and signed electronically; the Commercial Code gives electronic signatures legal effect and gives an advanced electronic signature (firma electrónica avanzada) the same weight as a handwritten one. For ordinary private service contracts no specific form is required.
The law
- Código de Comercio, Title II (arts. 89–114) on electronic commerce and electronic signatures
- Código Civil Federal, art. 1834 bis — consent expressed by electronic means
- Ley de Firma Electrónica Avanzada (2012) — dealings with public authorities
What still needs wet ink, a notary or a qualified signature
- Acts that must be executed before a notary public (e.g. real estate transfers, certain corporate acts)
- Wills
- Family-law and civil-status acts
Where Clinch fits
Clinch is built for everyday commercial agreements — freelance and agency contracts, statements of work, NDAs, quotes and service agreements — which in Mexiconeed no special form. Every signature is captured with the signer's explicit consent, and the signed PDF carries an audit trail (name, email, timestamp of every event, hashed IP) plus a SHA-256 fingerprint of the exact document, so anyone can check it was not changed after signing.
It is a simple electronic signature, not a qualified one: for the documents listed above, use the formality the law requires.
