California Durable Power of Attorney Requirements

A California power of attorney is legally sufficient when it states its date of execution, is signed by the principal (or, at the principal’s direction and in the principal’s presence, by another adult on the principal’s behalf), and is either acknowledged before a notary public or signed by two qualifying witnesses (Cal. Prob. Code § 4121). Durability is never automatic: the instrument must contain express language stating that it survives the principal’s incapacity, or the agent’s authority ends when the principal loses capacity to contract (§§ 4124, 4155).

This page is a practitioner reference for attorneys and paralegals handling California matters. It summarizes statutory requirements — it is not legal advice and does not substitute for reading the current statute or consulting California counsel.

The governing statute

Powers of attorney are governed by Division 4.5 of the Probate Code, which § 4000 designates the Power of Attorney Law. California has not adopted the Uniform Power of Attorney Act. It did adopt an older, narrower uniform scheme: § 4001 provides that only seven specific sections — §§ 4124, 4125, 4126, 4127, 4206, 4304, and 4305 — “may be cited as the Uniform Durable Power of Attorney Act.” A practitioner arriving from a UPOAA state should expect the durability rule, the statutory form, and the third-party refusal scheme to diverge from what the uniform act supplies.

Division 4.5 does not reach health care decisions. Section 4050(a)(1) expressly excludes powers of attorney for health care, which are governed instead by Division 4.7.

Citation: Cal. Prob. Code §§ 4120–4130 (creation), §§ 4200–4266 (attorneys-in-fact), §§ 4400–4465 (statutory form) Official source: leginfo.legislature.ca.gov

California statute uses attorney-in-fact; § 4014(a) treats “agent” and any other term the instrument uses as equivalent.

Execution requirements

Two rows carry more weight than the table alone shows. Section 4121(c)’s notary-or-witnesses choice is not the whole picture: § 4402(c) requires acknowledgment outright for the statutory form, and a third party’s good-faith reliance protection under § 4303(a)(3) depends on the instrument bearing either a notarial certificate or two witness signatures — the disjunctive travels with the instrument into how third parties treat it. And § 4128’s warning-language mandate is narrower on its face than practitioners often assume: it reaches printed forms “sold or otherwise distributed… for use by a person who does not have the advice of legal counsel,” language that does not obviously sweep in an attorney-drafted instrument, though including the notices is the conservative choice and § 4101(b)(1) bars the instrument from limiting a required warning in any event.

Where the statute is silent

Division 4.5 as researched does not address remote online notarization — California’s notary authority sits in the Government Code and Civil Code, outside this research. It imposes no recording requirement for a POA affecting real property beyond the § 4128 notice’s observation that recording is easier with a notarial acknowledgment. And it sets no deadline for a third party to accept or refuse a general (non-statutory-form) power of attorney; § 4406(a)’s “reasonable time” standard applies only to the statutory form.

Powers requiring an express grant, and third-party acceptance

Section 4264 is the most practically valuable list in Division 4.5. An attorney-in-fact may take the following actions only if the power of attorney expressly grants that specific authority:

• Create, modify, revoke, or terminate a trust, in whole or in part — and where the grant covers modifying or revoking a trust the principal created, the agent may act only as the trust instrument itself provides (§ 4264(a))
• Fund, with the principal’s property, a trust not created by the principal or by a person authorized to create a trust on the principal’s behalf (§ 4264(b))
• Make or revoke a gift of the principal’s property, in trust or otherwise (§ 4264(c))
• Reject, disclaim, release, or consent to reducing or modifying a share in, or payment from, an estate, trust, or other fund (§ 4264(d))
• Create or change survivorship interests in the principal’s property (§ 4264(e))
• Designate or change beneficiary designations that take effect at the principal’s death (§ 4264(f))
• Make a loan to the attorney-in-fact (§ 4264(g))

Section 4465 extends the same rule to the statutory form — executing the § 4401 form confers none of these powers unless the form expressly grants them. Section 4265 is an absolute bar with no express-grant workaround: a power of attorney can never authorize an agent to make, publish, declare, amend, or revoke the principal’s will.

On acceptance, § 4300 generally requires a third person to give an attorney-in-fact acting under a power of attorney the same rights and privileges the principal would receive if personally present. A third person is not required to honor the agent’s authority, however, if the principal could not require the third person to act or conduct business in the same circumstances. Section 4301 permits a third person to rely on and deal with the attorney-in-fact concerning the subjects and purposes encompassed or expressed in the power of attorney, without requiring the instrument to expressly authorize the specific act, transaction, or decision. Section 4303(a) protects a third person acting in good-faith reliance when the instrument is presented by the named attorney-in-fact, appears valid on its face, and contains either a notary public’s certificate of acknowledgment or two witness signatures.

Refusal carries a cost. Once the attorney-in-fact furnishes an affidavit under § 4305 — stating no actual knowledge of revocation, termination, death, or incapacity — that affidavit is conclusive proof of nonrevocation as to good-faith acts taken in reliance on it. If a third person still refuses after the affidavit is furnished, § 4306 makes that person liable for the attorney’s fees incurred in an action to confirm the agent’s authority, unless the court finds a good-faith belief that the agent was unqualified or exceeding authority.

For the statutory form specifically, § 4406 provides that an agent may bring an action to compel a third person to honor the agent’s authority if the third person refuses within a reasonable time. The third person cannot be compelled to act if the principal could not compel the third person to act in the same circumstances. If an action is brought, the court must award attorney’s fees to the agent when it finds that the refusal was unreasonable. A refusal is deemed unreasonable if its only basis is that the power of attorney is not on the third person’s own form, although § 4406(c) recognizes that state or federal law may authorize or require a refusal.

Durable Powers of attorney executed outside California

Section 4053 is a broad recognition rule. A durable power of attorney executed in another state or jurisdiction, in compliance with that jurisdiction’s law or with California law, is valid and enforceable in California to the same extent as one executed here — regardless of whether the principal is a California domiciliary.

Section 4052 addresses the reverse: where the instrument states that California’s Power of Attorney Law governs, Division 4.5 applies to the agent’s acts inside or outside California if any of five connecting factors is present — California domicile of the principal or agent at execution, California-situs authority, acts occurring or intended to occur in California, California execution, or any other reasonable relationship to California.

Recognition under § 4053 does not repair a defectively drafted foreign instrument. Because § 4124 requires an express durability statement and § 4155 terminates a nondurable POA on incapacity to contract, an out-of-state instrument that never made itself durable under its own governing law does not become durable simply by being brought into California.

Related California documents

The § 4264(a) trust-modification power does not stand alone: Cal. Prob. Code § 15401(c) independently bars an attorney-in-fact from modifying or revoking a trust unless the trust instrument permits it, so the two documents have to be drafted together — see the California revocable living trust requirements page. Because Division 4.5 excludes health care decisions, a California plan needs a separate instrument under Division 4.7; the California advance health care directive requirements page covers those formalities, which are stricter than these. And § 4265’s absolute bar on will-related authority is the boundary explained on the California will execution requirements page.

Where a California POA breaks down in practice, it’s usually because a § 4264 power the client actually needed was never expressly granted — a drafting-checklist problem, which is what estate planning document drafting software is built to catch.

Online notarization in California. As of September 2026, California-commissioned notaries are not yet authorized to perform remote online notarizations. Senate Bill 696 authorized RON in stages, but the operative provisions allowing California notaries to perform remote notarizations will take effect when the Secretary of State completes the required technology project or on January 1, 2030, whichever occurs first.

California Civil Code § 1182 permits an acknowledgment to be taken outside California but within the United States by a notary public or another authorized officer acting within the officer’s jurisdiction. Section 1189(b) provides that an acknowledgment taken elsewhere is sufficient in California if it complies with the law of the place where it was made. Whether a particular out-of-state remote acknowledgment satisfies these provisions therefore depends on the governing jurisdiction’s law and the circumstances of the notarization.

California residents may obtain an acknowledgment on a power of attorney from a properly authorized out-of-state remote online notary when the notary acts within the notary’s jurisdiction and the acknowledgment complies with the law of the place where it is made. California Civil Code §§ 1182 and 1189(b) recognize an out-of-state acknowledgment that satisfies those requirements.
