Federal Apostille Glossary
Plain-English definitions of the terms you’ll meet when getting a U.S. federal document ready for use abroad.
Quick answer
An apostille authenticates the signature on a public document for use in Hague Convention countries. Federal documents get theirs from the U.S. Department of State; state and notarized documents from a state authority. Non-Hague countries need authentication plus embassy legalization instead.

Frequently asked questions
What's the difference between an apostille and legalization?
An apostille is a single certificate accepted by Hague Convention countries. Legalization is the longer route for other countries: Department of State authentication, then the destination's embassy.
What is a certified copy?
A copy issued by the agency or court holding the original, with that authority's certification and seal. For most federal documents, it's what gets apostilled — not a photocopy.
Does notarizing a federal document help?
No. Notarization invalidates a federal record for federal authentication. It only applies to private documents, which then take the state route.
