affidavit

An affidavit ( (listen) AF-i-DAY-vit; Medieval Latin for he has declared under oath) is a written statement of fact voluntarily made by an affiant or deponent under an oath or affirmation which is administered by a person who is authorized to do so by law. Such a statement is witnessed as to the authenticity of the affiant's signature by a taker of oaths, such as a notary public or commissioner of oaths. An affidavit is a type of verified statement or showing, or in other words, it contains a verification, which means that it is made under oath or penalty of perjury, and this serves as evidence for its veracity and is required in court proceedings.
Affidavits may be written in the first or third person, depending on who drafted the document. The document's component parts are typically as follows:

a commencement which identifies the "affiant of truth", generally stating that everything in it is true, under penalty of perjury, fine, or imprisonment;
an attestation clause, usually a jurat, at the end certifying that the affiant made oath and the date;
signatures of the author and witness.If an affidavit is notarized or authenticated, it will also include a caption with a venue and title in reference to judicial proceedings. In some cases, an introductory clause, called a preamble, is added attesting that the affiant personally appeared before the authenticating authority.
