An affidavit is a written statement made under oath, often used in legal proceedings. It is a way for individuals to present facts or evidence in a formal manner. The person making the affidavit, known as the affiant, swears that the information provided is true to the best of their knowledge. Affidavits can be used in various situations, such as court cases, property disputes, or to verify identity. They must be signed in the presence of a notary public or another authorized official to ensure their validity. This process helps maintain the integrity of the information presented.
