General information only. This guide is not legal, financial, or tax advice. Requirements depend on the document and situation.
What an acknowledgment does
For an acknowledgment, the signer personally appears and acknowledges having executed the document. The notary establishes identity and completes the acknowledgment certificate. The acknowledgment concerns identity and the signer’s acknowledgment of execution; it does not make the notary responsible for the truth, accuracy, or legal validity of the document.
A document may have been signed before the appointment when an acknowledgment is requested, provided the signer personally appears and gives the required acknowledgment. Do not rely on that general description when the recipient has provided different execution instructions.
What a jurat does
For a jurat, Government Code section 8202 requires the notary to administer an oath or affirmation, identify the affiant through satisfactory evidence, and have the affiant sign in the notary’s presence. The signer is swearing or affirming that the statement is true.
Because the signature-presence and oath requirements differ from an acknowledgment, signing a jurat document before the notary arrives can create a problem. Leave the relevant signature unsigned unless the document recipient or preparing professional has confirmed another lawful procedure.
The notary cannot choose for you
Selecting a certificate can require understanding the document’s legal purpose. A California notary who is not acting under another professional license cannot decide which act the signer needs. If the document does not contain a certificate or clear instructions, contact the recipient, issuing agency, lender, escrow officer, or attorney.
The notary can show or describe the available certificate forms without recommending one. Once the signer or authorized requesting party identifies the act, the notary can determine whether its legal requirements can be completed.
Questions to ask the recipient
Ask whether the signature needs an acknowledgment or a sworn jurat, whether the signature must occur during the appointment, whether witnesses are also required, whether a specific certificate format is required, and where the completed document should be delivered.
Resolve those questions before a mobile visit whenever possible. A notary appointment is faster and less stressful when the requested act is already known.
Fees and multiple signatures
California Government Code section 8211 sets maximum fees for specified notarial services. The number of signers, number of notarized signatures, and number of certificates can affect the notarial total. Mobile travel, parking, printing, waiting, after-hours scheduling, or other separately agreed services are different from the statutory notarial fee.
Send the notary the signer and signature count—not private document contents—to receive a useful estimate.
A simple appointment example
If a title company instructs a seller to acknowledge a deed, the seller appears, presents satisfactory identification, and acknowledges execution; the notary completes the requested certificate. If an agency requires an affidavit with a jurat, the affiant appears, presents satisfactory identification, takes an oath or affirmation, and signs in the notary’s presence.
These examples explain process only. The recipient must confirm which act belongs with the actual document.
Put this guide into practice
If the document does not tell you which act is required, pause before booking and ask the recipient a precise question: “Does this signature require an acknowledgment or a jurat?” Written instructions can prevent a second visit and help the notary bring the appropriate certificate wording.
Do not use the page’s general examples to select an act for yourself. The notary can perform the requested act when its conditions are satisfied, but the document’s legal purpose belongs with the recipient or a qualified adviser.
