what's the apostille?

The term apostille from the Latin postilla (explanation, note) consists of the affixing, generally by a Court of Justice, of a seal (stamp) bearing this mention to attest to the conformity of documents produced in accordance with your country of residence's law. It was introduced by the Hague Convention of 5 October 1961, ratified by 97 States, which abolished the requirement of legalisation of foreign public documents as a substitute for legalisation of a public document. This is a simplified legalization procedure that attests to the authenticity of the signature, the status of the person signing the public deed and legalizes the signature of the registrar who has himself legalized a document. It replaces by a single formality the requirement of legalisation of an official document from a country that is a signatory to the Hague Convention. (examples: notarial deeds, civil status, power of attorney, passport, etc.).
