The use of electronic signature mechanisms is legally valid in most of the countries in the world. These mechanisms are nothing more than elements to prove the willingness of the parties to accept the terms or agreements of a contract. It is then a proof of evidence (electronic evidence) and effective in court as the signature is linked to the strong evidences collected through the electronic signature processes.
It is clear that if the system complies with the legislation in force that each country sets out, the probative value and thus the automatic recognition of its legal validity will be much greater, but this does not mean that otherwise it will no longer have probative value, returning to the proof of evidences collected throughout the operations.
