A second state authority (Department of Foreign Affairs) verifies the signature of the first level state authority (notary public). This is called an apostille or legalisation
Please note: The type of authentication will depend on the entity that will receive the documents.
If the country where the document will be used is party to the Hague Convention, an apostille will be affixed. In cases where the country where the document will be used is not party to the Hague Convention, the Department of Foreign Affairs will affix an authentication, and the document will then need to be legalised.
