US apostille provides a certification service for the marriage certificate issued by the US Health Departments (Bureau of Vital Statics), which is intended to be used in the Apostille countries of The Hague.

We received an apostille for the certificate of non-registration of marriage from the Office of the Secretary of State in the same state in which the document was issued.

Failure to register a marriage is a mandatory certification to prove the uniform status of the holder if he plans to marry abroad.

It is also sometimes called a Single Status Certificate, certificate of No Impediment, or No Marital Status.
