(Reliable Notification)

Electronic Notification

Fast, affordable and with full legal force

Certified SMS/EMail consists in sending relevant information through an SMS short message or email aimed at obtaining legal certification of its contents, the submission and the delivery to the recipient. To that end, the submission date and time are certified, along with the sender's and recipient's phone numbers or emails.

Full legal force

With the same legal and probative value as a registered fax (bureaufax) or registered letter, Certified SMS has probative value before the Courts as an evidence that the submission was made in a secure and provable manner.

Digital Certificate

All data are certified by Aviva Voice (holding a Licence from the Spanish Telecommunication Market Commission CNMC) and Camerfirma, the Certification Authority established by the Chambers of Commerce, which includes its Digital Timestamp. The result is a PDF file with Certified Digital Signature.
