An affidavit is based upon either the personal knowledge of the affiant or his or her information and belief. Personal knowledge is the recognition of particular facts by either direct observation or experience. Information and belief is what the affiant feels he or she can state as true, although not based on firsthand knowledge.
An affidavit is a written statement of facts voluntarily made by an affiant under an oath or affirmation administered by a person authorized to do so by law.
