This checklist helps you prepare for your estate planning notarization (e.g., Will, Power of Attorney, Advance Health Care Directive) and explains what to expect during the appointment.
Valid government-issued photo ID
(Driver’s license, state ID, or passport must be current or within allowed limits)
Original estate planning documents
(Do not sign anything in advance)
Any required witnesses (if instructed by your attorney)
Witnesses must be adults (18+)
Witnesses must be mentally competent
Witnesses should not be named in the documents
Reading glasses (if needed)
All parties who need to sign must be present
Review your documents with your attorney ahead of time
Confirm whether witnesses are required
Ensure names on your ID match the documents
Have a clean, quiet space with a table for signing (for mobile signings)
The notary will:
Verify each signer’s identity using valid ID
Confirm willingness and awareness (no pressure or confusion)
Ensure documents are signed in the notary’s presence
Administer oaths or acknowledgments as required
The notary cannot:
Give legal advice
Explain or interpret documents
Tell you what you should sign
Last Will and Testament
Power of Attorney (Financial)
Advance Health Care Directive / Living Will
Property Deeds (if applicable)
Trust-related signature pages (not the trust creation itself)
In California, certain estate planning documents require one or more witnesses in addition to notarization to ensure the signing is valid and legally enforceable.
Witnesses provide an extra layer of protection by confirming that:
The signer is the correct person
The signer is signing voluntarily and without pressure
The signer appears mentally aware and competent at the time of signing
This helps prevent fraud, undue influence, or future disputes and strengthens the document if it is ever challenged in court.
Must be 18 years or older
Must be mentally competent
Should not be named in the documents or benefit from them
Must be physically present at the time of signing
In some cases, witnesses must observe each other sign
Your attorney will advise whether witnesses are required and how many are needed, as requirements vary by document type under California law.
Mistakes can occasionally happen during a signing. What matters most is how they are handled.
Do not alter or white-out notarized documents
If a signer makes a mistake, the notary will stop and advise whether the document can be corrected or must be reprinted
Any corrections must be done before notarization and in accordance with California notary law
If a California notary makes an error (such as a missing seal, incorrect certificate, or journal issue), the notary will take immediate steps to correct it. This may include:
Correcting the notarial certificate properly
Re-notarizing the document if required
Coordinating with the signing party or attorney to ensure compliance
If reprinting is not possible, the notary will explain the available options, which may include attaching a correct California notarial certificate or rescheduling the notarization if required by law.
California notaries are required to follow strict legal standards, and accuracy is taken seriously to protect all parties involved.
Can a California notary also act as a witness?
In California, a notary public should not act as a witness for a document they are notarizing. A notary must remain an impartial public official, and serving as both can create a conflict of interest.
Can a family member be a witness in California?
California law allows family members to act as witnesses in some situations, but they should not be named in the documents or benefit from them. Attorneys often recommend neutral third-party witnesses to avoid future challenges.
How many witnesses are required in California?
This depends on the document. For example, a California will generally requires two witnesses, while other estate planning documents may require none or one. Your attorney will confirm what applies to your documents.
Do witnesses need to bring ID in California?
Witnesses are not usually required to present ID to the notary, but they should have valid identification available if requested by the attorney or institution.
Do witnesses need to stay for the entire appointment?
Yes. Witnesses must be present during the signing of the documents they are witnessing and may need to observe each other sign.
What if I don’t have witnesses?
Please check with your attorney in advance. Some California notaries may be able to help arrange witnesses with prior notice, depending on availability.
