You can digitally certify your private agreement. For the digital certification, you will need:

• either your personal internet banking credentials or your personal Taxisnet credentials (after first registering in the National Communication Register (EMEP), to confirm your mobile phone number)
• your mobile phone number, to which the confirmation codes will be sent before the document is issued
• the Tax Identification Numbers (AFM) and names of the issuers who co-sign the document
• the document you wish to certify electronically in.pdf format

When you upload the private agreement you want to digitally certify, you choose whether the digital certificate to be created will be in Greek or English. If you choose English, the first and last name in Latin characters are automatically drawn, for each issuer co-signing the document, but you have the option to modify them.

All other signatories, after visiting docs.gov.gr and selecting the "Digital Certificate of Private Agreement", need to select the "Pending issues" field to locate the document to be signed and sign it. Only when the process is completed by all parties, the digitally authenticated signed document appears in the Citizen's Inbox of each signatory.

With the digital certificate, the unique verification identification number in alphanumeric and QR format is printed at the bottom of each page of your document, and, at the end of the document, the electronic stamp of gov.gr and the issuer's details are also printed.

The digital private agreement certificate you will issue is legally equivalent to a document bearing the authenticity of the signature and you can either send it electronically, or print it and submit it in hard copy.
