Authentication is testimony by a proper party that a document is what it is purported to be and that the party attesting to it is qualified to do so. Some of the requirements for authentication may include:
The U.S.Constitution, Art. IV s. I, states, 'Full faith and credit shall be given in each state to the public acts, records and judicial proceedings of every other state. And congress may by general laws prescribe the manner in which such acts,, records and proceedings shall be proved, and the effect thereof.'
