How to Notarize a Affidavit
A sworn written statement used as evidence in court or legal proceedings.
Overview
An affidavit is a written statement made under oath and notarized by a commissioned notary public. It serves as a legal declaration of facts and is commonly used in court proceedings, immigration cases, insurance claims, and various legal matters. The notarization confirms that the affiant (person making the statement) appeared in person, provided identification, and swore or affirmed the truthfulness of the statement.

- An affidavit is a sworn statement — lying in an affidavit constitutes perjury
- The notary performs a jurat (oath/affirmation), not an acknowledgment, for affidavits
- Do not sign the affidavit before your notary appointment
- The notary does not verify the truth of your statements — only your identity and willingness to swear
Cost
Notary fees for a jurat are typically $2-$15 per signature depending on state law, plus any travel fees for mobile service.
