Authentication (sometimes also referred to as âlegalizationâ) is the certification of the genuineness of the signature and seal of an official. Through this process, it is attested that the official has the authority to execute, issue or certify a document in one jurisdiction, so that it may be recognized in another jurisdiction. Authentication does not certify the genuineness, legality or credibility of the documents or their contents. The process of authentication aims at confirming, for the civil and judicial officials of a country, that the signature and seal of an official affixed to a document that was issued in another country, are authentic.
