California Power of Attorney Attorney
Last updated: August 2026
A power of attorney lets someone you choose act for you on financial and property matters. The version that matters for estate planning is the durable one, because it survives your incapacity — which is the moment it exists for. Without it, your family may need a conservatorship to pay your bills: a public court proceeding, with ongoing supervision, that costs more than the document would have. Bay Legal, P.C. prepares durable powers of attorney as part of a California estate plan and advises agents on their authority and duties.
Definition: A power of attorney is a written authorisation letting a person you name, called your agent or attorney-in-fact, act on your behalf on matters you specify.
We had an excellent experience working with Sivendra Maraj from Bay Legal, to draft our trust, will, and power of attorney documents. We were on a tight deadline, needing to get everything finalized within a week, and Sivendra was incredibly prompt in his responses.

Which type of power of attorney do you need?
California’s Power of Attorney Law sits at Probate Code section 4000 and following. Four types come up, and the distinction between the first two is the one that matters most.
| Type | Survives incapacity? | Typical use |
|---|---|---|
| General | No — it terminates when you lose capacity | Convenience during travel or a defined period. Not an incapacity plan |
| Durable | Yes | Estate planning. The one almost everyone needs |
| Limited or special | Depends how it is drafted | A single transaction — a property closing, a specific account |
| Health care | Yes | Medical decisions. In California this is part of the advance health care directive rather than a separate instrument |
The trap is the first row. A general power of attorney terminates at exactly the moment most people assume it starts working. Under Probate Code section 4022, a power of attorney is durable only if it contains language showing you intended it to survive your incapacity. Without that language it is not durable, whatever the document is titled.
What must a California power of attorney contain?
Under Probate Code section 4121, it must be in writing, signed by you or by someone at your direction in your presence, and either acknowledged before a notary public or signed by at least two adult witnesses. Either route satisfies the statute.
In practice, use the notary. A county recorder will not record a real property transaction on a witnessed power of attorney, and most banks and brokerages will not accept one. The statutory alternative exists; relying on it will cost you the transaction you needed the document for.
Probate Code section 4128 additionally requires a warning statement to the principal in a statutory form, and section 4406 provides a Uniform Statutory Form Power of Attorney that satisfies the requirements. Like the health care directive form, it is genuinely usable for straightforward situations and inadequate for complicated ones.
What can your agent not do without express authorisation?
This is the most important section on the page and it was absent from the previous version. Under Probate Code section 4264, certain acts require express authorisation in the document itself. A general grant of broad authority does not cover them. They include:
- Creating, modifying, revoking, or terminating a trust
- Making or revoking a gift of your property
- Creating or changing survivorship interests
- Designating or changing beneficiaries
- Waiving your right to be a beneficiary of a joint and survivor annuity or a retirement plan
- Exercising fiduciary powers you hold and are permitted to delegate
These are sometimes called hot powers, and the omission is not academic. An agent who needs to move an asset into the trust to complete funding, or to update a beneficiary designation after a death, cannot do it if the document does not say so — and the moment that is discovered is usually the moment it is too late to fix, because you no longer have capacity to sign a new one.
They are also the powers most open to abuse, which is why the statute requires them to be granted deliberately rather than swept in. Whether to include them, and with what limits, is the substantive conversation to have when the document is drafted.
What duties does an agent owe?
Fiduciary duties, enforceable in court. Probate Code section 4231 and following requires an agent to act loyally in the principal’s interest, keep the principal’s property separate from their own, keep records of all transactions, and act within the authority granted. An agent who self-deals, commingles funds, or exceeds their authority is personally liable, and abuse of an elder principal can carry additional consequences under California’s elder abuse statutes.
Two practical points for anyone accepting the role. Keep a separate file and a clear record from day one — reconstructing years of transactions later is far harder than recording them as you go. And sign as agent rather than in your own name, so the transaction is on the principal’s account and not personally yours.
Can a bank refuse to accept a power of attorney?
Sometimes, and this is a frequent frustration. Probate Code section 4300 and following governs third-party reliance. A third party who acts in good faith on a power of attorney is generally protected, which is the mechanism intended to encourage acceptance. But section 4306 allows refusal in defined circumstances — where the third party knows the power has terminated, doubts its validity or the agent’s authority, or has made a reasonable request for confirmation that has not been met.
Practical ways to reduce friction: use a notarised document rather than a witnessed one, provide the institution with a copy well before it is needed rather than in a crisis, complete the institution’s own form alongside the statutory document where it offers one, and grant the specific authorities the transaction will require rather than relying on general language. A document drafted years earlier and never shown to the bank is the version most likely to be questioned.
When does a power of attorney end?
Under Probate Code section 4152, a power of attorney terminates on your death, on your revocation, when the document says it does, on the agent’s death, incapacity, or resignation where no successor is named, or on a court order. Divorce or annulment terminates a former spouse’s authority as agent unless the document provides otherwise.
Two things it does not do. It does not survive your death — the agent’s authority stops there and the executor or successor trustee takes over, which surprises families who assume the agent can keep paying bills. And it does not, by itself, give the agent authority over assets held in your trust; the trust’s own terms and its successor trustee provisions govern those. A complete plan needs both instruments and they need to be consistent.
Who prepares powers of attorney at Bay Legal?
Sivendra Ganesh Maraj leads estate planning and probate. Rachael Berg handles trust and estate matters alongside him. A durable power of attorney is normally prepared with the rest of a plan — a living trust, a pour-over will, and an advance health care directive — because the four documents have to work together, particularly on the hot powers question and on the boundary between the agent’s authority and the trustee’s.

Frequently Asked Questions
What is the difference between a general and a durable power of attorney?
A general power of attorney terminates when you lose capacity. A durable one survives it, which is the whole point of having one for estate planning. Under Probate Code section 4022 a power of attorney is durable only if it contains language showing you intended it to continue, regardless of what the document is titled.
Does a California power of attorney have to be notarised?
Not as a matter of law. Probate Code section 4121 permits either acknowledgment before a notary or signature by two adult witnesses. In practice, use the notary: county recorders will not record real property transactions on a witnessed document, and most banks and brokerages will not accept one.
What are hot powers, and why do they matter?
Acts that require express authorisation in the document under Probate Code section 4264 — creating or amending a trust, making gifts, changing survivorship interests or beneficiary designations, and waiving retirement plan survivor benefits. A general grant of broad authority does not cover them, and the omission is usually discovered when it is too late to sign a new document.
Can my agent be held responsible for misusing the authority?
Yes. An agent owes fiduciary duties under Probate Code section 4231 and following: loyalty, keeping the principal’s property separate, record-keeping, and staying within the authority granted. An agent who self-deals or exceeds their authority is personally liable, and abuse of an elder principal can carry consequences under California’s elder abuse statutes.
Why won’t my bank accept my power of attorney?
Probate Code section 4306 permits a third party to refuse in defined circumstances, including doubt about validity or the agent’s authority. A notarised document, provided to the institution before it is needed rather than during a crisis, completed alongside the bank’s own form where one exists, is far less likely to be questioned.
Does a power of attorney work after I die?
No. It terminates on death under Probate Code section 4152. Authority passes to the executor named in the will or the successor trustee of the trust. Families often assume the agent can continue paying bills after a death, and acting on a terminated power of attorney creates real exposure for the agent.
Related Questions
Do I need a power of attorney if I have a living trust?
Yes. A trust covers assets held in the trust. A power of attorney covers everything outside it — retirement accounts, which cannot be held in a trust, plus tax filings, insurance, and government benefits. The two instruments cover different property and a complete plan has both.
Can I name more than one agent?
You can, either jointly or with authority to act independently. Requiring agents to act jointly is a safeguard that becomes an obstacle when one is unreachable. Naming successors in order is usually more workable than naming co-agents.
What is a springing power of attorney?
One that takes effect only on a stated event, usually a determination of incapacity. It sounds prudent and often causes delay, because someone must first establish that the triggering event occurred before the agent can act.
How do I revoke a power of attorney?
In writing, and then by notifying the agent and every institution that holds a copy. Revocation nobody has been told about is the version that causes problems, since a third party acting in good faith on the old document is generally protected.
Is a power of attorney from another state valid in California?
Often, but acceptance is a separate question from validity. An out-of-state document that a California bank or recorder declines to accept is of little use, so anyone relocating should execute a California document.
Talk to a California estate planning attorney
A durable power of attorney is only useful if it was signed while you had capacity, which means the window to create one closes exactly when the need becomes obvious. To prepare or review one with a Bay Legal attorney, call the office nearest you or email intake.
