Acknowledgment vs. Jurat: Which One Does Your Document Need?

The two most common notarial acts, how they differ, and why your notary is not allowed to pick one for you.

Reviewed October 2026 by Katherine Perron, New York State Notary Public

Nearly every notarization is one of two acts. They look similar on paper, but they certify different things, and using the wrong one can get your document rejected.

Acknowledgment

In an acknowledgment, you declare to the notary that you signed the document and did so willingly. The notary certifies your identity and that you acknowledged the signature.

  • Used for deeds, mortgages, powers of attorney, and most contracts.
  • The wording usually begins "On the ___ day of ___, before me personally appeared..."
  • You do not swear to anything about the contents.

Jurat

In a jurat, you sign in front of the notary and swear or affirm that the contents of the document are true. The notary administers the oath.

  • Used for affidavits, sworn statements, and many applications.
  • The wording usually reads "Sworn to before me this ___ day of ___."
  • You must sign in the notary's presence. Lying under that oath can be perjury.

Why the notary cannot choose for you

Deciding which notarial act a document needs is a legal judgment, and a notary who is not an attorney is not permitted to make it. If your document has no notary wording, ask the agency or person who requested it which act they want. Once you tell the notary, they can attach the right certificate.

Other acts you may run into

  • Oath or affirmation: a spoken oath with no document signature, for example swearing in a witness.
  • Copy certification: New York notaries cannot certify copies of public records such as birth certificates. Certified copies come from the office that issued the record.

Common questions

What if my document has no notary section?

Ask the person or agency that needs the document which notarial act they require. The notary can then attach the correct certificate.

Can a New York notary certify a copy of my birth certificate?

No. Certified copies of vital records come from the issuing office.
