What Is an Apostille?

Apostille (pronounced uh-pos-til) is a form of international certification used to authenticate official documents for use in other countries. It is part of the 1961 Hague Convention, which allows public documents from one member country to be recognized as valid in another—without requiring further legalization through embassies or consulates.

In short, an Apostille confirms:

  • The document is genuine
  • The signature and seal are authentic
  • The issuing authority is recognized in the country of origin

Whether you need to send a birth certificate, FBI background check, corporate agreement, or academic record overseas, an Apostille ensures your paperwork is accepted abroad by Hague Convention member countries. If your destination country is not a member, consulate or embassy legalization may be required instead.
