Certificate of Apostille
An Apostille or Certificate of Authority certifies that documents intended for use in foreign countries as legally authenticated. The Michigan Office of the Great Seal, and some branches of the Secretary of State, handle Apostilles and Certificates of Authority. Apostilles are used for countries that are party to the Apostille Treaty, while Certificates of Authority can be issued for non-party countries. Apostilles and Certificates of Authority are issued for public documents and are the equivalent of notarization within the United States.
