Notarisation of a copy of a document

You need the services of a notary public when you have to have the authenticity of a copy of a document officially certified.

When you need to have the authenticity of a copy of a document officially certified, you have to deliver the original document to the Digital and Population Data Services Agency.

The original document provided by you will be photocopied at the agency. The notary public will then certify the authenticity of the copy.

Do the following

  • Deliver the original document to one of the offices of the Digital and Population Data Services Agency.

  • You do not need to visit the agency in person.


  • A document can be authenticated if the signature on it is hand-written or it has an ink stamp, a seal or a similar identifying factor.

  • Photocopies or prints are not accepted.

  • If an indicator of originality is missing from the document, turn to the party that issued the document and ask them to provide the required markings indicating originality.


The notarisation of a copy costs EUR 4 per page.

Processing time

If the notary public is available, you will get a certified copy of your document while you wait.
