Mexico is one of the countries with the highest business volume using electronic signatures and therefore the use of the electronic signature in Mexico is mostly regulated. The legal regulation is Law DOF 11-01-2012. This law gives legal value to electronic transactions, thus providing full legal validity to the advanced electronic signature, defined as:
”Collection of datasets and characters that enable to identify the signatory, created by electronic means under his sole control in a way that is uniquely linked to the signatory and to the data which he is associated to, and with the same legal effect as a handwritten signature”.
Thus, parties must meet two requirements: to have a digital certificate in force and a private key generated under their sole control.
