NotaryLA Editorial Team March 20, 2026

An affidavit is a written statement made under oath and notarized by a notary public. It is one of the most common reasons people visit a notary, used in everything from court proceedings to immigration applications to business filings. Understanding how affidavit notarization works helps you prepare properly and avoid delays.

What Is an Affidavit?

An affidavit is a legal document in which the signer (called the "affiant" or "deponent") swears under oath that the statements within the document are true and correct. Because the affiant is swearing under penalty of perjury, an affidavit carries significant legal weight. Making false statements in a notarized affidavit is a criminal offense.

Common Types of Affidavits

Affidavit vs. Acknowledgment: The Key Difference

Affidavits require a jurat, which is different from an acknowledgment. Understanding the distinction is important:

The notarial certificate attached to an affidavit will include language such as "subscribed and sworn to before me" to indicate a jurat was performed.

The Affidavit Notarization Process

  1. Prepare the affidavit: Draft the document, but do not sign it yet. You must sign in front of the notary.
  2. Bring valid photo ID: Current government-issued photo identification is required.
  3. Appear before the notary: Present yourself in person before the notary public.
  4. Take the oath: The notary administers an oath or affirmation. You will raise your right hand and swear (or affirm) that the statements in the affidavit are true.
  5. Sign the affidavit: Sign the document in the notary's presence.
  6. Notary completes the jurat: The notary fills in the jurat certificate, applies their seal, and signs.
