What a Signature Affidavit Is and When it’s Used
A Signature Affidavit is a sworn, written statement used to confirm the authenticity of a signature on a separate document or to attest to facts about how or when a signature was created. It is executed under oath or penalty of perjury and typically includes identifying information, the signer’s declaration, factual details, and a notary or witness acknowledgement. In U.S. practice a Signature Affidavit is often used when originals are unavailable or signatures are disputed; it supports recordkeeping, evidentiary needs, and downstream filings that require proof of signature origin.
