Acknowledgments and jurats are the two most common notarial acts in California. They sound similar but serve different legal purposes. Using the wrong one can invalidate the document and expose you to liability. Here’s what each requires and when to use them.

The Short Version

• Acknowledgement — the signer confirms they signed the document. A notary verifies identity and willingness but does not need to watch the signing happen.
• For a jurat, the signer swears that the document contents are true and signs right in front of the notary, who administers an oath and witnesses the signature.

Both acts help prevent fraud, but they are not interchangeable.

Acknowledgement: When and How

An acknowledgement is used when someone needs to prove they signed a document. The notary’s job is to confirm the signer’s identity and verify that they are acknowledging their signature willingly.

Common uses

Deeds, mortgages, trust documents, and powers of attorney. These are documents recorded with the county or submitted to institutions where the main concern is proving who signed it. Real estate transactions almost always require acknowledgments.

Steps

1. The signer appears before you in person.
2. You verify their identity using an acceptable ID (driver’s license, passport, etc.).
3. You ask if they acknowledge that they signed the document willingly.
4. You complete the notarial certificate, sign it, and apply your seal.

The signer does not have to sign the document in front of you. They can sign it earlier. You are confirming that the person in front of you is the same person who signed it. This is why acknowledgments are common for documents signed days or weeks before closing.

Jurat: When and How

A jurat is used when the signer needs to swear that the contents of a document are true. The notary administers an oath and watches the person sign.

Common uses

Affidavits, declarations, depositions, and certain court filings. These are documents where the truthfulness of the content matters. If a court or government agency needs the signer to swear something is true, it needs a jurat.

Steps

1. The signer appears before you in person.
2. You verify their identity.
3. You administer an oath or affirmation (the signer swears the contents are true).
4. The signer signs the document in your presence.
5. You complete the jurat certificate, sign it, and apply your seal.

The signing must happen in front of you. If the document is already signed when the signer arrives, have them sign it again or cross out the old signature and re-sign.

Key Differences at a Glance

• Oaths? Only a jurat requires one.
• Signing must happen in the notary’s presence for a jurat, not for an acknowledgement.
• They serve different purposes: acknowledgements prove who signed, while jurats prove the signer swears the content is truthful.
• Acknowledgements appear on deeds, mortgages, and POAs, while jurats appear on affidavits and depositions.
• A journal entry is required for both.
• Either type costs $15 per signature — the California maximum fee applies equally to both.

Practical Scenarios

Here are some common situations and which act applies:

• Someone brings a deed for a house sale — use an acknowledgement. They likely signed at home and need to prove it was actually them.
• A friend needs a sworn statement for a court case? That’s a jurat. You’ll administer the oath and watch them sign.
• Travel consent letters for minors usually call for an acknowledgement, since the parent has already signed and needs identity verification.
• When an employee signs an affidavit about a workplace incident, go with a jurat. The signer must swear the statements are true under penalty of perjury.
• A couple signing a power of attorney needs an acknowledgement. The point is proving they signed it, not affirming its truthfulness.

California Certificate Requirements

California has mandatory wording for both types of notarial certificates. Government Code 8202 sets the acknowledgment language and Government Code 8203 sets the jurat language. The certificate must include your name, the date, the state and county, and a statement that the signer personally appeared before you.

For acknowledgments, the certificate must state that the signer acknowledged signing the document. For jurats, it must state that the signer was sworn and signed in your presence. You cannot modify the statutory wording. If the document has out-of-state notarial language, attach a California-compliant loose certificate.

What the Signer Chooses, Not the Notary

The signer or document recipient decides whether they need an acknowledgment or a jurat. The notary does not make this choice. If a signer asks what type they need, explain the difference and let them decide. If the document has pre-printed notarial wording, use that type.

Common Mistakes

• Using the wrong certificate type is the most common error. That means an acknowledgement when a jurat is required, or vice versa.
• Skip the oath on a jurat and it’s not valid, period.
• The signer must sign in front of you for a jurat. Not before, not after.
• Every notarization needs a journal entry. Skipping it isn’t optional.
• Documents prepared out of state may contain notarial language that doesn’t meet California requirements. Instead of using that wording, attach a California-compliant loose certificate.

Frequently Asked Questions

Can I use an acknowledgement instead of a jurat?

No. The type of notarization depends on the document and what it requires. If a document needs a jurat (like an affidavit), an acknowledgement will not work.

Does the signer need to bring an unsigned document for a jurat?

Preferably yes, since they must sign in your presence. If the document is already signed, have them re-sign it in front of you.

What is the fee for an acknowledgment or jurat in California?

The maximum fee is $15 per signature for either type. Mobile notaries can also charge a travel fee. See our guide on how much a notary costs in California.

Do I need to record an acknowledgement in my journal?

Yes. California requires a journal entry for every notarization, including acknowledgements.

Can I notarize a document that is already signed?

For an acknowledgement, yes. The signer can sign beforehand. For a jurat, no. The signer must sign in your presence.
