What is an Affidavit?

A written document signed under oath before a notary public or other authorized person affirming that the statements in the document are true, that regularly serves as testimony in a court.

Many court filings, such as petitions for divorce initiating suit, require that an affidavit be submitted with the filing that asserts the necessary facts to validate the filing at its initial stage. They act as sworn testimony for purposes of establishing perjury or for undermining the credibility of a witness when they forget what they swore to in the affidavit and later provide conflicting testimony.
