The role of certified email as legal evidence in commercial trials
Will paper ever disappear as a medium of evidence in courts dealing with commercial matters? There are many companies in the commercial sector that ask themselves this question and, given the lack of unanimity in the answer, prefer to continue with the traditional format of paper documents for all their dealings.
However, despite all these advantages of digital communication tools, there are those who prioritize the legal aspect. They want to be sure that their negotiations and commercial agreements communicated through digital channels can be presented as reliable evidence in court.
Well, we argue why the certified email fully guarantees this legal validity. First of all, because an amendment has been made to the Code of Civil Procedure (Article 299.2), which includes these supports as evidence with legal value in a trial as long as these criteria are met:
- Guarantee the integrity and unalterability of the content and all data.
- The date and time of shipment can be checked and verified.
These requirements are met in certified digital mailings, provided that they are carried out by a Qualified Trust Service Provider, which is approved to perform this function by the Ministry for Digital Transformation and the Civil Service.
This homologation means that the data sent and received through these applications will be admitted as evidence in legal proceedings, even if they are in electronic format, as everything is produced according to the provisions of the regulation (EU) 910/2014 eIDAS.
