General Business Use (Yes)

Whilst 100% legal; there are exceptions for very specific types of transactions. It is still up to the discretion of the independent user, or governing body, whether they are used or not. As each business needs are different and the agreements themselves may vary. We always advise you to speak with an authority within your businesses category.

Court-Admissible (Yes)

Each country has its own regulations that determine whether an electronic signature is seen as legal or not. So, as long as your electronic signature adheres to these, a signature won’t be rejected simply for not being handwritten.

e-Signature Legal Model (Tiered)

Mexico’s legal model is a tiered one. Although Tiered, Qualified Electronic Signatures (QES) will not receive any legal status as there are no specific conditions for this electronic signature type This doesn’t mean that a non-QES e-Signature can’t be submitted in court, but it will need extra evidence to support it.

eSignature Legality Summary

Electronic signatures are valid and enforceable in Mexico and create legal obligations among contracting parties, provided that such signatures satisfy certain technical requirements set forth in Article 97 of Mexico’s Commerce Code (CC). Mexico recognizes simple electronic signature as legally enforceable by following a two tier jurisdiction where it gives these digital signatures the same status as handwritten one. Countries around the world that follow this model have an opportunity to select signature forms based on the convenience and use cases. Recently Mexico amended several of its federal and commerce laws to permit the use of electronic signatures wherein parties are generally free to choose the type of signature as per acceptance of agreement.

The eSignature Legality Guide is the result of legal research into the laws and practices regarding eSignature on a country-by-country basis. Each country-level analysis was conducted by local law firms located in that country, in that country’s local language. This legal analysis was then supplemented with complementary research on eSignature and digital signature technology standards conducted by independent technology experts. Together, this information is provided as a public resource to understand eSignature legality, and clarify some of the common misconceptions about international eSignature legality.


A basic measure of eSignature legality in a country is whether courts will admit eSignatures as evidence in court. In most countries in the world, an eSignature cannot be rejected simply because it is electronic, meaning that it should be admissible, subject to proof. Learn more about how DocuSign helps you prove an eSignature validity in court, below.


While there are exceptions for very specific types of transactions, eSignatures, independent of the underlying technology, may be used for the majority of general business transactions in most countries. Issues that may restrict general business use include local technology requirements or other restrictions on special transactions types. Learn more about specific transaction types, below.


‘Tiered’ countries recognize Qualified Electronic Signature (QES, or the locally named equivalent) as a distinct type of eSignature. In these countries, a QES has special legal status in the form of presumed authenticity, and may be legally required for a few, specific transaction types. In spite of this, a non-QES eSignature can still be submitted as evidence in court even in Tiered countries, so long as the party presenting it has sufficient evidence to prove that it is valid. Countries imposing QES standards often struggle to promote electronic business transactions, especially across country borders. ‘Open’ countries have no such technology requirements or eSignature types that receive special legal status.
