Why Identification Is Critical
Verifying the identity of the signer is the most fundamental duty of a notary public. If you notarize a document for someone who is not who they claim to be, you could be liable for fraud, face disciplinary action, and lose your commission.
Identification requirements are the single highest-weighted topic on the California notary exam, with approximately 8-10 questions dedicated to this subject.
California Acceptable ID Documents
Under California Civil Code Section 1185, a notary can accept the following forms of identification:
- A driver's license or state-issued ID card from any US state
- A US passport or passport card
- A foreign passport or consular ID from the signer's country of citizenship
- A US military ID with photo, serial number, and description
- An inmate identification card issued by a California correctional facility
The ID must be current or have been issued within the last 5 years, and contain a photograph, physical description, and signature. A document that meets these criteria from any US state is acceptable — it does not have to be a California ID.
Texas Acceptable ID Documents
Texas notaries can verify identity through three methods under Tex. Gov't Code Section 406.014:
1. Personal knowledge — You personally know the signer
2. Government-issued photo ID — A current identification document issued by a government agency that contains a photograph and signature
3. Credible witness — A person you know (or who presents ID) who personally knows the signer and swears to their identity
Texas is less prescriptive than California about specific ID types. Any government-issued photo ID with a signature is generally acceptable.
Important: Texas law specifically prohibits recording the signer's ID number in your record book (1 TAC Section 87.40). Record the type of ID and issuing agency, but NOT the ID number.
What About Expired IDs?
This is one of the most commonly tested topics on both state exams.
CALIFORNIA: An expired ID can still be acceptable. Under Civil Code Section 1185, every acceptable ID document must be current OR have been issued within the last 5 years. If a signer presents an expired driver's license that was issued more than 5 years ago, you cannot use it for identification purposes. If the ID shows no issue date, it must be current.
TEXAS: State law requires a current government-issued ID. An expired ID should not be accepted.
If a signer does not have an acceptable ID, you may use the credible witness process instead.
The Credible Witness Process
When a signer cannot produce acceptable ID, the credible witness process provides an alternative method of identification.
CALIFORNIA allows two options:
1. Single credible witness: One person who personally knows BOTH the notary AND the signer, swears under oath to the signer's identity, and presents acceptable ID to the notary
2. Two credible witnesses: Two people who each personally know the signer (but do not need to know the notary), each swear under oath to the signer's identity, and each present acceptable ID to the notary
TEXAS: A credible witness who personally knows the signer can vouch for their identity. The witness must either be personally known to the notary or present acceptable ID.
The credible witness must have no financial interest in the document being notarized.
Common Exam Traps About Identification
Watch for these traps on the exam:
1. A signer shows a credit card with their name — NOT acceptable (not government-issued, no photo or physical description)
2. A signer shows an expired passport — in California, acceptable only if it was issued within the last 5 years (the ID must be current or issued within 5 years)
3. A signer says 'everyone knows me in this town' — NOT acceptable (personal knowledge must come from the NOTARY or a credible witness, not general reputation)
4. An employer vouches for an employee — NOT automatically acceptable unless they qualify as a credible witness
5. A social security card — NOT acceptable (no photo)
6. In California, a single credible witness must know BOTH the notary and the signer — this is the detail most people miss
Frequently Asked Questions
Can a notary accept an expired ID?
It depends on the state. In California, an expired ID is acceptable if it was issued within the last 5 years, because Civil Code Section 1185 accepts an ID that is current or was issued within five years. An expired ID issued more than 5 years ago is not acceptable. Texas requires a current government-issued ID.
What can a notary do if someone has no ID?
If a signer cannot produce acceptable identification, the notary can use the credible witness process. In California, either one witness who knows both the notary and signer, or two witnesses who each know the signer, can verify the signer's identity under oath.
Can a notary accept a foreign ID?
In California, a passport or consular ID from the signer's country of citizenship is acceptable on its own, as is a Canadian or Mexican driver's license, if it has a photo, description, signature and number. In Texas, any government-issued photo ID with a signature may be considered acceptable.
