Reform To The Mexico City Civil Code Regarding Digitalization Of Legal Acts

On August 20, 2026, the “Decree amending Article 1834 of the Civil Code for the Federal District” was published in the Mexico City Official Gazette. This reform unifies the rules on the use of electronic means in contracts, without altering the previously applicable legal regime.

1. Validity of the use of electronic means

The reform confirms that the written-form requirement is deemed satisfied when electronic, optical, or any other technological means are used.

For these means to be valid, the information must be kept in its entirety, be attributable to the signatories, and remain accessible for future consultation.

2. Digital notarial protocol

As already provided in the Civil Code, where the law requires a legal act to be formalized before a notary public, the reform allows this to be done through a digital protocol.
