Definition of an Affidavit

An Affidavit is a sworn statement of fact written by deponent or an affiant under an oath taken by an officer authorized by the law.

An affidavit is generally characterized as a voluntary, written statement taken under an oath, witnessed as well as signed by an authorized official, and used for the purpose of evidence in the court.

However, since an affidavit is a legally binding document, therefore, in case the oath contains false documentation, the individual who signed it is liable to be accused of perjury.

The person who takes oath on an affidavit is called an Affiant under affiant law.

Purpose of an Affidavit

An affidavit can be utilized for a number of reasons. Most of the time, the court requires you to file an affidavit to prove that the information you’re presenting is based on facts. However, in certain cases, like in various legal proceedings, your attorney can utilize your affidavit to save you a trip to the court. In this way, an affidavit can save you a considerable amount of time as well as money.
