Affidavits

 An affidavit is the written version of swearing under oath to tell the truth, just as if you were testifying in a courtroom. The document is signed both by the person making the statement, called an affiant, and by a person who is legally authorized to administer an oath, such as a notary public or certain court and government officers.
