The authenticity of an American document (e.g. birth or marriage certificate) is confirmed by the interior governmental authorities from the issuing State (Secretary of State) with a so-called Apostille.
In all cases, the certificate(s) must be enclosed with a letter written in English requesting the Apostille in accordance with the Hague Convention, along with the name of the country where the documents are to be submitted.
The documents requiring the Apostille, must include the original signature (signed notarization) from a registered notary or an official of the U.S. State, who is registered with the Department of State, or with the Secretary of State or with the Department of the Treasury.
In cases of civil status documents, in which the issuing person has not personally signed, but rather whose signature is presented as a facsimile signature on the document, must in addition obtain the original signature of the issuer before the super legalization and accordingly, the Apostille can beissued.
The Apostille is issued by the Secretary of State from the U.S. State in which the particular certificate was issued.
