Mexico is one of the countries with the highest business volume using electronic signatures and therefore where this 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.
