Ask for a document to be “notarized,” and the notary may ask a follow-up question: acknowledgment or jurat?

Most people have no idea — and that’s completely normal. In many cases, the document already tells you which notarial act is required. You just need to know where to look.

‍

What is an acknowledgment?

An acknowledgment is a notarial act in which the signer appears before a notary, proves their identity, and declares that the signature on the document is theirs and that they signed willingly. The notary isn't vouching for what the document says. Deeds and powers of attorney usually take an acknowledgment.

What is a jurat?

A jurat is a notarial act in which the signer swears or affirms, under penalty of perjury, that the contents of the document are true, and signs in the notary's presence. The notary administers a spoken oath or affirmation. Affidavits and sworn statements usually take a jurat.

Common certificate wording

"…acknowledged before me…"

"Subscribed and sworn to (or affirmed) before me…"

A summary from the California Lawyers Association's Real Property Law Section puts the main difference simply: the oath. A jurat involves swearing to the truth of the document's contents, while an acknowledgment confirms identity and voluntary signing.

How to tell which one your document needs

  1. Look at the bottom of the signature page or the page right after it. If there's a block of notary wording with blanks for a date, county and notary signature, that's the certificate. Read its key phrase: "acknowledged" points to an acknowledgment, and "sworn," "subscribed and sworn" or "affirmed" points to a jurat.
  2. If there's no certificate, ask whoever prepared or will receive the document: your attorney, the title company, the court clerk or the agency. They know what they need.
  3. Don't expect the notary to choose. In many states the notary isn't allowed to decide which act you need, because that can amount to legal advice. The notary can attach the certificate you specify.

Can you sign before you see the notary?

For an acknowledgment, often yes. The signer appears and acknowledges an existing signature. Many states allow this, but some document preparers still want you to sign in front of the notary, so follow their instructions.

For a jurat, no. You have to sign in the notary's presence after taking the oath or affirmation. A jurat page signed in advance usually has to be reprinted and signed again. StampSpot's appointment checklist recommends leaving every signature line blank until the notary is ready, which avoids the problem entirely.

Oath or affirmation: is there a difference?

Both carry the same legal weight. An oath traditionally references a deity, while an affirmation is a pledge on your personal honor. A notary should let you choose either one for a jurat. Neither one makes the content of the document legally correct. It only puts you on record as swearing that it's true.

What happens if the wrong certificate is used

A mismatched certificate is one of the errors county recorders regularly cite when they list common notary mistakes. A deed with a jurat instead of an acknowledgment, or an individual acknowledgment on a document signed by a corporate officer, can be returned unrecorded. The fix usually means signing and notarizing again, which hurts most on a real estate file with a deadline. The real estate notarization guide lists other errors that delay recording.

Other notarial acts you might see

  • Copy certification: the notary certifies that a copy matches the original. Only some states allow it, and generally not for public records such as birth certificates, which have to come from the issuing agency.
  • Signature witnessing: some states have a separate act where the notary confirms they watched you sign, without an oath.
  • Oath or affirmation alone: given verbally, sometimes for testimony, with no document certificate.

Frequently asked questions

What is the main difference between an acknowledgment and a jurat?

A jurat includes an oath or affirmation that the document's contents are true, and an acknowledgment doesn't. An acknowledgment only confirms who signed and that they signed willingly.

Which one does a deed need?

Deeds almost always take an acknowledgment. Check the certificate printed on the deed or ask the title company.

Which one does an affidavit need?

Affidavits usually take a jurat, since the signer is swearing the statements are true.

Can a notary tell me which one to use?

Usually not. Choosing can be considered legal advice. Ask the person who drafted or will receive the document.

Can I use an acknowledgment if I've already signed?

Often yes, if your state allows it and the document preparer agrees. You'll still need to appear before the notary with ID.

Getting it right the first time

When you book through StampSpot, you can message the notary before the appointment and send them the certificate page, so they arrive knowing whether you need an acknowledgment, a jurat or both. The Features page lists the document types notaries on the platform handle, from affidavits to full real estate packages.
