Overview
This chapter explains how a California notary identifies a signer. The law calls this "satisfactory evidence," and it is required for acknowledgments and jurats. It means there is nothing that would make a reasonable person doubt the signer's identity, plus either an acceptable ID or the sworn word of credible witnesses.
A California notary may not identify a signer by personal knowledge alone, even a family member or coworker. The notary may rely on a California driver's license or ID card, a U.S. passport, and certain other cards listed in the law, such as another state's driver's license or a U.S. armed forces ID. The ID must be current or issued within the last five years.
When a signer has no acceptable ID, credible witnesses may identify the signer under oath. The law allows one credible witness who personally knows both the signer and the notary, or two credible witnesses who do not know the notary, each with acceptable ID. A credible witness must have no financial interest in the document and must not be named in it.
A notary who fails to obtain the satisfactory evidence the law requires can face a civil penalty of up to $10,000. The notary records how identity was proven in the journal, including the type of ID, the agency that issued it, its serial number, and its date of issue or expiration.

Credible witnesses
One credible witness who personally knows the notary and the signer, or two credible witnesses who do not know the notary but know the signer. Each must show acceptable ID and take an oath.
Memory tipKnown to notary = 1. Unknown = 2.

Credible witness oath
The witness swears that the signer is the person named, that the witness personally knows the signer, that the signer has no acceptable ID, and that getting one would be very difficult or impossible. The witness has no financial interest and is not named in the document.
Memory tipKnows signer, no ID possible, no stake.

3 sample questions
Verified practice questions from this unit.
Question 1. Which ID may a California notary rely on to identify a signer?
- ① A California driver's license that is current or was issued within the last five years
- ② A library card with the signer's name
- ③ A Social Security card
- ④ A credit card with the signer's photo
▼ Show answer and explanation▲ Hide answer and explanation
Answer: ① A California driver's license that is current or was issued within the last five years
Key point: CA driver's license is acceptable ID
A California driver's license or ID card from the DMV is acceptable when it is current or was issued within the last five years.
Wrong choices
- A library card with the signer's name: A library card is not an acceptable ID.
- A Social Security card: A Social Security card has no photo or description and is not on the list.
- A credit card with the signer's photo: A credit card is not on the list of acceptable IDs.
Question 2. A signer has no acceptable ID. How many credible witnesses are needed if the witness personally knows both the notary and the signer?
- ① Two
- ② One
- ③ None; the notary may accept the signer's word
- ④ Three
▼ Show answer and explanation▲ Hide answer and explanation
Answer: ② One
Key point: One credible witness if known to notary
One credible witness is enough when the witness personally knows both the notary and the signer, shows acceptable ID, and takes the required oath.
Wrong choices
- Two: Two credible witnesses are used when they do not personally know the notary.
- None; the notary may accept the signer's word: Without ID, credible witnesses are required.
- Three: California never requires three credible witnesses.
Question 3. A notary's longtime neighbor asks for an acknowledgment but has no ID with them. May the notary identify the neighbor by personal knowledge?
- ① Yes, for acknowledgments but not for jurats
- ② No, California notaries may not identify signers by personal knowledge alone
- ③ Yes, if the notary has known the neighbor for at least 5 years
- ④ Yes, if the notary writes "personally known" in the journal
▼ Show answer and explanation▲ Hide answer and explanation
Answer: ② No, California notaries may not identify signers by personal knowledge alone
Key point: Personal knowledge is not enough in CA
In California, satisfactory evidence means an acceptable ID or credible witnesses. A notary may not rely on personal knowledge alone, even for a family member or neighbor.
Wrong choices
- Yes, for acknowledgments but not for jurats: The rule applies to both acts.
- Yes, if the notary has known the neighbor for at least 5 years: There is no time-based personal knowledge rule in California.
- Yes, if the notary writes "personally known" in the journal: Personal knowledge is not satisfactory evidence in California.
