In California, the person giving the power (the principal) signs the power of attorney in front of a notary after showing acceptable photo ID, and leaves a thumbprint in the notary's journal. A durable power of attorney for finances must be notarized or signed by two qualified witnesses, and notarization is needed if it will be used for real estate. SD Fast Notary can come to your home, hospital, or care facility in San Diego to notarize it.

Who needs to be there
Only the principal (the person granting authority) needs to sign in front of the notary. The agent does not usually need to be present. The principal must be alert, understand what they are signing, and sign willingly. A notary must refuse if the signer appears confused or pressured.
What to prepare
- The complete power of attorney, unsigned, with all pages
- The principal's acceptable photo ID (see ID rules)
- Witnesses, if your document or facility requires them
Hospitals and nursing homes
If the principal is in a hospital, we can come to the bedside. For an advance health care directive signed by a patient in a skilled nursing facility, California requires a patient advocate or ombudsman to serve as a witness. Arrange this with the facility in advance. Learn about hospital notary visits.
Certified copies of a POA
A California notary can make a certified copy of a power of attorney (Probate Code §4307), one of the few documents a California notary may certify as a copy. This is helpful when banks ask for a copy and you want to keep the original.
Which form should I use?
A notary cannot choose or prepare a POA for you. Use a form from your attorney, or California's statutory form. For complex estates, speak with an estate planning attorney.
Frequently asked questions
Does a power of attorney have to be notarized in California?
A durable power of attorney for finances must be either notarized or signed by two qualified witnesses. If it will be used for real estate transactions, it must be notarized so it can be recorded.
Can the agent sign on behalf of the principal at the notary?
No. The principal must personally sign in front of the notary. If the principal cannot sign their name, California allows a signature by mark with two witnesses.
Can you notarize a POA for someone in the hospital?
Yes, as long as the patient is alert, can communicate directly with the notary, understands the document, and has acceptable ID or credible witnesses.
How much does it cost to notarize a power of attorney in San Diego?
The notarial fee is $15 per signature by California law. Mobile visits add a travel fee that we quote upfront.
