NotaryLA Editorial Team February 8, 2026

A power of attorney is one of the most important legal documents you can create. It authorizes someone you trust to act on your behalf in financial, legal, or healthcare matters. In California, notarizing your power of attorney is strongly recommended and, in many cases, legally required. This guide explains everything you need to know about POA notarization.

Types of Power of Attorney in California

General Power of Attorney

Gives your agent broad authority to handle financial and legal matters on your behalf. This document becomes invalid if you become incapacitated.

Durable Power of Attorney

Similar to a general POA, but remains in effect even if you become mentally incapacitated. California law requires a durable power of attorney to be notarized. This is the most commonly used POA for estate planning.

Limited (Special) Power of Attorney

Grants authority for a specific task or time period, such as selling a particular property or handling a single financial transaction. Commonly used when you cannot be present for a real estate closing or title transfer.

Healthcare Power of Attorney

Also known as a healthcare directive or medical power of attorney. Authorizes your agent to make medical decisions if you cannot. In California, this can be either notarized or signed by two qualifying witnesses.

Why Notarization Is Essential

While not every power of attorney legally requires notarization in California, getting your POA notarized provides significant advantages:

How to Get Your Power of Attorney Notarized

  1. Prepare the document: Have your POA drafted by an attorney or use a California-compliant legal form. Ensure it includes all required statutory language.
  2. Bring proper identification: The principal must present a valid, current government-issued photo ID. The agent (person receiving power) does not need to be present.
  3. Appear before the notary: The principal must appear in person before the notary public. If the principal is homebound or in a care facility, a mobile notary can travel to their location.
  4. Sign in the notary's presence: The principal signs the POA while the notary observes.
  5. Notary completes certification: The notary fills in the acknowledgment certificate, applies their seal, and signs the document.

Special Considerations

Capacity Assessment

The notary must assess whether the principal appears to understand what they are signing and is acting voluntarily. If the principal seems confused, disoriented, or under duress, the notary can and should refuse to notarize the document. This is a critical safeguard against elder abuse.

Hospital and Home Notarizations

Powers of attorney are frequently needed in urgent situations, such as when someone is in the hospital or a care facility. Hospital notary services and mobile notaries can accommodate these time-sensitive needs. Many offer same-day and emergency service.

Out-of-State Use

A power of attorney notarized in California is generally valid in other states. However, if the POA will be used for real estate transactions in another state, check that state's specific requirements. For international use, you may need an apostille.

Cost of POA Notarization

The notary fee for a power of attorney in California is $15 per signature. Most POAs require only one or two signatures, so the notary cost is typically $15 to $30. If you use a mobile notary, add a travel fee of $25 to $75.

How Long Is a Power of Attorney Valid?

A POA remains valid until the principal revokes it, the principal dies, or the specified term expires. A non-durable POA also terminates if the principal becomes incapacitated. Some institutions may question a POA that is several years old, so keeping it relatively current is wise. Learn more in our guide on how long notarization is valid.
