Explore the BoldSign features that make eSigning easier.

With the quick advancement of technology, there has been a greater need for a modern technique to approve signatories to a document. This necessity has greatly predisposed the idea of having an electronic signature.

Users are required to select a service that adheres to the legal frameworks in Mexico, including the Federal Civil Code, Federal Commerce Code, and the Official Mexican Standard NOM-151-SCFI-2016. These laws acknowledge electronic signatures as bearing the same legal weight as their handwritten counterparts. However, certain documents might still necessitate a traditional signature, and the legal obligations for these can differ across various regions. The stipulated guidelines define criteria that a user must fulfil to establish the legitimacy of an electronic signature. BoldSign is recognized for integrating security measures that guarantee compliance with these regulatory and security protocols.

From an international law angle, electronic signatures were regulated by the Model Law of Electronic Commerce of the United Nations of 1996 (MLEC)[1]. Member states to the United Nations and Economic Blocks have developed their framework in line with MLEC. Specifically, on this page, we will be focusing on Mexico.

Electronic signatures can be defined as the legal concept capturing one’s intention to be bound by the contents of a given document.[2] In Mexico, electronic signatures are legally recognized when they can be clearly linked to the signer and verified for authenticity, providing protection against fraud. These eSignatures must indicate the signer’s intentional Agreement to the document’s terms and are treated with the same validity as traditional handwritten signatures if the criteria are satisfied.

Generally, an eSignature is accepted to hold the same legal image as a wet ink signature. Even though the Mexican legal framework lacks an expressed provision on how electronic signature is to operate, the use in completing transactions is regulated by:

Article 1811 of the Federal Civil Code, in giving recognition to electronic signatures, opines that signatures affixed on contracts written on electronic messages will be recognized when they can be attributed to the person acquiring the obligation and the related information can be accessible for future reference.

The regulations categorize eSignatures into two:

A standard eSignature means any letters, characters, numbers, sound, process, or symbols in electronic form attached to, or logically associated with information that is used by a signatory to indicate his intention to be bound by the content of that information.

Advanced electronic signature is under Article 97 of the Federal Commerce Code, defined as an eSignature which meets conditions such as:

Unique data that correspond exclusively to the signatory

A secure electronic signature must be uniquely connected to the person who is using it. The signature must be uniquely made with methods that only the signer has access to, like a private key and confidential info, to verify their identity.

The signature creation data was, at the time of signing, under the exclusive control of the signatory

The person using the secure electronic signature must have sole control over the means of creating the signature. Typically, this requires managing a key pair or two-factor authentication, with the signer exclusively holding the private key to prevent unauthorized signature forgery.

Possibility to detect any change to the electronic signature made after its moment of creation

The integrity of an electronic signature is paramount, and various technologies are used to ensure that any changes made to the signature or the document after the moment of creation are detectable. This is achieved through audit trails and timestamps.

Possibility to detect any alteration of the data message after its time of signing

It is essential to preserve the authenticity of the signed document. Modifications made to the document post-signature should be identifiable. This is commonly accomplished through an audit trail. Audit trails record the signer’s IP address, timestamps of key signing events, and location, providing proof of identity, timing, and place of signature.

Article 8 of the Federal Advanced Electronic Signature Act sets out certain standards to be met in operating an advanced electronic signature. These standards are:

Under the Federal Civil Code, Federal Commerce Code and Official Mexican Standard NOM-151-SCFI-2016

Documents that can be signed

Electronic signatures can be employed to affix signatures and provide countersignatures on a diverse array of documents, such as:
