California Power of Attorney Laws (2026)

A California power of attorney (POA) lets one person (the principal) authorize another (the attorney-in-fact, or agent) to manage financial, legal, or property matters on their behalf. California governs financial POAs under its own Power of Attorney Law, Cal. Prob. Code sections 4000-4545, not the Uniform Power of Attorney Act. To survive the principal's incapacity, the document must expressly state it is durable. Healthcare decisions are handled under a completely separate statute.

What a Power of Attorney Does in California

A power of attorney is a written document by which a principal grants an agent authority to act on their behalf. The scope can be broad (covering real estate, banking, business operations, and more) or narrow (limited to a single transaction or subject). California law defines "power of attorney" under Cal. Prob. Code section 4022 as a written instrument granting authority to an attorney-in-fact.

The agent acts in a fiduciary capacity. Under Cal. Prob. Code section 4231, the agent must meet the standard of care of a prudent person dealing with another's property. An agent with special skills (such as a financial professional) is held to the higher standard of others with similar expertise.

California also offers a Uniform Statutory Form Power of Attorney under Cal. Prob. Code sections 4400-4465. This pre-approved form, most recently revised effective January 1, 2012, covers common financial subjects and is widely accepted by banks and other institutions. Readers who want a document to work from can create a California-specific power of attorney and sign and notarize the result.

Durable vs. Non-Durable Power of Attorney in California

By default, a POA executed in California is non-durable: it terminates if the principal loses legal capacity to contract. A non-durable POA is typically used for a specific transaction while the principal is fully competent.

A durable POA remains effective even after the principal becomes incapacitated. Under Cal. Prob. Code section 4124, durability requires express language in the document. Acceptable phrases include:

• "This power of attorney shall not be affected by subsequent incapacity of the principal."
• "This power of attorney shall become effective upon the incapacity of the principal." (This creates a "springing" durable POA, which only activates upon incapacity.)
• Any similar words clearly showing the principal intends authority to continue despite incapacity.

Without one of these phrases, the document is non-durable and ends the moment the principal becomes incapacitated. Most estate planning POAs use the first option to ensure continuous authority. If the point of the document is to cover a future incapacity, ask a California estate planning lawyer for a free case evaluation to confirm the durability language is in it before signing (attorney advertising).

How to Create a Valid California Power of Attorney

Under Cal. Prob. Code section 4121, a California POA is legally sufficient when all of the following are satisfied:

1. Principal's signature. The document must be signed by the principal, or by another adult in the principal's presence and at the principal's direction if the principal is unable to sign personally.

2. Date. The document must state the date of execution.

3. Notary or two witnesses. The principal's signature must be either acknowledged before a notary public OR signed in the presence of at least two adult witnesses. The witnesses must personally observe the principal sign or hear the principal acknowledge the signature, per Cal. Prob. Code section 4122. The named attorney-in-fact cannot serve as a witness.

For the statutory form POA under Cal. Prob. Code section 4402, acknowledgment before a notary is required. Recording the document with the county recorder is required only if the POA will be used for real estate transactions.

What a California Agent Can and Cannot Do

General Financial Authority

How far an agent's authority reaches depends on whether the document grants general or limited authority. Where a POA grants general authority and is not limited to one or more express actions, subjects, or purposes, the agent has all the authority to act that a person having the capacity to contract could carry out through a specifically authorized attorney-in-fact (Cal. Prob. Code section 4261). Where a POA grants only limited authority, the agent has the authority granted, as limited with respect to permissible actions, subjects, or purposes, plus the authority incidental, necessary, or proper to carry out that granted authority (Cal. Prob. Code section 4262). Either way, the hot powers described below require express authorization in the document. A broadly drafted POA can authorize banking, investing, paying bills, managing real estate, operating a business, handling tax matters, and similar financial tasks.

Fiduciary Duties

The agent must act solely in the interest of the principal and avoid conflicts of interest (Cal. Prob. Code section 4232). California law does not require an agent to act unless they have agreed in writing to do so, but once the agent begins a task they must complete it (Cal. Prob. Code section 4230).

Hot Powers (Require Express Authorization)

Certain high-risk actions cannot be taken unless the POA document specifically and expressly authorizes them. Under Cal. Prob. Code section 4264, these "hot powers" include:

• Creating, modifying, revoking, or terminating a trust
• Making gifts of the principal's property
• Changing beneficiary designations on accounts or insurance
• Creating or altering survivorship rights in property
• Disclaiming estate or trust interests
• Making loans to the agent (self-dealing)
• Funding trusts not originally created by the principal

If the document does not mention these powers, the agent simply cannot exercise them. Principals should think carefully before including any hot power.

Medical Power of Attorney in California

California does not use a "medical power of attorney" as a standalone instrument. Healthcare decision-making authority is governed by an entirely separate statute: the Health Care Decisions Law, Cal. Prob. Code sections 4600-4806.

The vehicle for delegating healthcare authority is the Advance Health Care Directive (AHCD). A single AHCD document can appoint a health care agent, set personal instructions for future care, or both. The optional statutory form is found at Cal. Prob. Code section 4701.

Execution requirements for an AHCD differ from those for a financial POA. An AHCD must be signed by two qualified witnesses OR acknowledged before a notary. Witness restrictions are strict: a witness cannot be the named health care agent, the principal's health care provider, an employee of that provider, an operator or employee of a community care facility or residential care facility for the elderly (Cal. Prob. Code section 4674). At least one of the two witnesses must be a person who is not related to the principal by blood, marriage, or adoption and is not entitled to any portion of the principal's estate (Cal. Prob. Code section 4674(e)). Patients in a skilled nursing facility also need a patient advocate or ombudsman signature.

A financial POA does not authorize healthcare decisions, and an AHCD does not authorize financial decisions. These are separate documents serving separate purposes.

Revoking or Ending a California Power of Attorney

How to Revoke

A principal retains the right to revoke a POA at any time while they have legal capacity. Under Cal. Prob. Code section 4153, revocation can occur in three ways:

1. By the document's own terms (for example, a POA that expires on a set date).
2. By direct notice to the agent, orally or in writing, that authority is revoked. This right cannot be waived or limited by the POA itself.
3. By the principal's court-appointed conservator or legal representative, with court approval, by written notice to the agent.

Third parties and agents who act in good faith without knowledge of a revocation are protected from liability under Chapter 5 of the Probate Code. For this reason, revoking a recorded POA used for real estate also requires recording a Notice of Revocation with the same county recorder.

Automatic Termination

Under Cal. Prob. Code section 4152, a POA also ends automatically upon:

• The death of the principal (the POA cannot authorize action after death)
• The principal's dissolution or annulment of marriage to the agent
• The death, resignation, removal, or incapacity of the agent (unless the POA names a successor agent)
• Fulfillment of the POA's stated purpose

A durable POA does NOT survive the principal's death. At death, the executor or administrator of the estate takes over; an agent has no authority to act after that point.

Frequently Asked Questions

Does California require a power of attorney to be notarized?

For a general financial POA under Cal. Prob. Code section 4121, notarization is one of two valid options: the principal's signature must be either acknowledged before a notary public or signed in front of two adult witnesses. Both satisfy the execution requirement. For the statutory form POA (sections 4400-4465), notary acknowledgment is required. If the POA will be used for real estate transactions, recording with the county recorder also requires notarization.

What language makes a California POA durable?

California Probate Code section 4124 requires express language in the document. The clearest phrasing is: 'This power of attorney shall not be affected by subsequent incapacity of the principal.' A 'springing' durable POA can instead say it 'shall become effective upon the incapacity of the principal.' Without this express statement, the POA automatically ends if the principal becomes incapacitated.

Can an agent make gifts under a California power of attorney?

Not automatically. Gift-making is a 'hot power' under Cal. Prob. Code section 4264, meaning the POA document must expressly authorize it. Without that specific language, the agent has no authority to give away the principal's property, even small amounts. Principals who want their agent to be able to make gifts (including annual-exclusion gifts to family members) must include explicit gift authorization in the document.

Is a California power of attorney valid after the principal dies?

No. Under Cal. Prob. Code section 4152, the principal's death is one of the events that automatically terminates the agent's authority. After death, the estate is managed by an executor or administrator under a will or intestate succession laws, not by the POA agent. A durable POA survives incapacity but not death.

How is a medical power of attorney handled in California?

California does not use a standalone 'medical power of attorney.' Instead, healthcare decision-making authority is granted through an Advance Health Care Directive (AHCD) under Cal. Prob. Code sections 4600-4806. The AHCD is a separate document from a financial POA and has different execution requirements, including strict witness qualifications. A financial POA cannot be used to make healthcare decisions.

How do I revoke a power of attorney in California?

Under Cal. Prob. Code section 4153, you can revoke a POA at any time while you have legal capacity, by telling the agent orally or in writing that authority is revoked. This right cannot be taken away by the POA document itself. To protect against third parties who may not know about the revocation, it is best practice to give written notice to any institutions that have a copy of the POA. If the POA was recorded with a county recorder for real estate purposes, you should also record a Notice of Revocation.

Did California adopt the Uniform Power of Attorney Act?

No. California has not adopted the 2006 Uniform Power of Attorney Act (UPOAA). California governs financial powers of attorney under its own Power of Attorney Law, codified at Cal. Prob. Code sections 4000-4545. California also maintains its own statutory form POA under sections 4400-4465. Residents and practitioners should rely on California's statutes rather than the UPOAA or forms designed for states that have adopted it.
