An affiant is a person who makes a sworn statement or affidavit, which is a written declaration made under oath. This document is often used in legal proceedings to provide evidence or support a claim. The affiant must sign the affidavit in the presence of a notary public or another authorized official to ensure its validity. Affidavits can be used in various contexts, such as in court cases, real estate transactions, or to verify information for government applications. The role of the affiant is crucial, as their testimony can significantly impact the outcome of legal matters involving judges, lawyers, or courts.
