The Hague Apostille Convention facilitates the circulation of public documents executed in one State Party to the Convention and to be produced in another State Party to the Convention. It does so by replacing the cumbersome and often costly formalities of a full legalisation process with the mere issuance of an Apostille. 45 years after its adoption, the Apostille Convention remains an essential and remarkably modern instrument of judicial and administrative cooperation.
Documents which have been notarized by a notary public, and certain other documents, and then certified with a conformant apostille are accepted for legal use in all the nations that have signed the Hague Convention, read more about the Convention on the following web-site: http://www.hcch.net/index_en.php?act=conventions.text&cid=41.
