The legalisation convention is the convention abolishing the requirement of legalisation for foreign public documents, also known as the Apostille Convention (5 October 1961). This convention does not completely abolish legalisation but shortens the chain so that only a single action is required, the addition of an apostille. A document bearing an apostille does not require any further legalisation by the embassy or consulate of the country in which it is to be used.
