How to sign the application and responsible statement?

It must be signed in such a way as to demonstrate the authenticity, integrity and unalterability of the document.

The telematics procedure authorised at the electronic site allows these documents to be signed at the same time as they are submitted, which is why it is essential that the person presenting the documentation at headquarters, be it the interested party himself or a valid representative of the interested party. 

Additionally, you can verify that a digital signature is correct, or sign a document, using the Valide platform.
