What is an Affidavit?
An affidavit is a legal document containing a written statement sworn under oath. Affidavits are often used in court proceedings, where a statement of the facts of a matter is required. When you write an affidavit and sign it, you’re swearing under the law that the information contained in the document is accurate.
Affidavits are signed voluntarily in the presence of witnesses and notarized by a public official. Meeting these requirements makes affidavits legally binding, and the signer risks the penalty of perjury if they lie.
