An affidavit is a written sworn statement of fact voluntarily made by an affiant or deponent under an oath or affirmation administered by a person authorized to do so by law. Such 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, meaning it is under oath or penalty of perjury, and this serves as evidence to its veracity and is required for court proceedings.
- To obtain a declaration on a legal document, such as an application for voter registration, that the information provided by the applicant is truthful to the best of the applicant’s knowledge. If, after signing such a declaration, the information is found to be deliberately untrue with the intent to deceive, the applicant may face perjury charges.
Affidavits may be written in the first or third person, depending on who drafted the document. If in the first person, the document’s component parts are:
- a commencement which identifies the affiant of truth”, generally stating that everything is true, under penalty of perjury, fine, or imprisonment;
- an attestation clause, usually a jurat, at the end certifying the affiant made oath and the date; and
- 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.
