In-person authentication service

Authenticating a document is free. It proves that the signature, the position of an official and the seal on a certified document are genuine. Other jurisdictions or countries will recognize your authenticated document as a valid copy.

Authentication is also called legalization or apostille.

Processing times

If the signature on the documents cannot be verified immediately, you will be advised to return to pick up your documents.

We can process up to 15 documents while you wait. If you have more than 15 documents, you must leave them with us and we will contact you when they are ready to be picked up. This could take up to five business days, depending on how many documents you need authenticated.

We will not process your documents faster for any reason. There are no exceptions.
