Authentications and Apostilles

"Authenticating" a document may also be called "verifying," "certifying," or attaching a "state seal." An "Apostille" is a specific format of an authentication certificate that is required by certain countries. When requesting authentication certificates from the Secretary of State's office, it is important to specify which foreign country is involved, so this Office can determine if an apostille or "regular" authentication is necessary. Use of the wrong certificate can cause a document to be rejected by the foreign country.
