California Power of Attorney Laws

If you become ill or injured and can't take care of your own finances, someone else must step in to help. Enter a handy document called a power of attorney (POA). A POA is a simple document that grants specific powers to someone you trust—called an "agent" or "attorney-in-fact"—that allows this person to deposit your checks at your bank, file your taxes, or even sell or mortgage your home on your behalf. Without this important document, your loved ones will have to go to court to get authority over your financial affairs if it ever becomes necessary.

Types of Powers of Attorney Available in California

You can make several different types of POAs in California. In particular, many estate plans include two POAs that are effective even if you become incapacitated:

• a financial POA, which allows someone to handle your financial or business matters, and
• a medical or health care POA, which allows someone to make medical decisions on your behalf. (In California, this POA is combined with a living will, which lays out your wishes for medical treatment. The combined document is called an "advance health care directive.")

Both of these POAs are what are known as "durable" POAs, which means that they retain their effectiveness even after you're incapacitated. It's a good idea for most people to create these two documents, as they help plan for the unexpected.

To learn about other types of POAs, including non-durable (limited) and springing POAs, see What Is a Power of Attorney. Below, learn how to create a durable financial POA that is valid in California.

Legal Requirements for a Financial Power of Attorney in California

For your POA to be valid in California, it must meet certain requirements.

Mental Capacity for Creating a POA

California requires that the person making a power of attorney have a certain mental capacity, called the "capacity to contract." Notably, this requirement is more stringent than the capacity to make a will or trust. If you're helping someone create a POA, at a minimum, you'll want to make sure that they're an adult who can:

• manage financial resources
• resist fraud, and
• resist undue influence.

(Cal. Civ. Code §§ 39(b), 1556; Cal. Prob. Code § 4120 (2025).)

If you're helping someone create a POA and you're not sure if they have the necessary mental capacity, consult a lawyer.

Witnessing and Notarizing Requirements

To make a POA in California, you must sign and date your POA in the presence of a notary public if you used a statutory form. If you didn't use a statutory form, you can either have the document notarized or sign it in the presence of two witnesses, or both. Your two witnesses must be 18 years old and can't be the agent you name in the POA. (Cal. Prob. Code §§ 4121, 4122, 4402 (2025).)

It's best to—at the very least—have your POA notarized, since many financial institutions will require it before they allow your agent to act under the POA. If you want your agent to conduct real estate transactions, your county land records office will require notarization as well.

Agent Signature

Some states, including California, require the agent to sign and date the POA as well. However, the agent need not do this until it becomes time to use the POA. (Cal. Prob. Code § 4128 (2025).)

Steps for Making a Financial Power of Attorney in California

1. Create the POA Using a Statutory Form, DIY Program, or Attorney

California offers a statutory form (a form drafted by the state legislature) with blanks that you can fill out to create your POA. The form isn't available in the online statutes, but several local government, court, and law library websites have the California form available. (Cal. Prob. Code § 4400 and following (2025).)

For a more user-friendly experience, try Nolo's Quicken WillMaker & Trust, which guides you through a series of questions to arrive at a POA that meets your specific aims and is valid in your state. (You can also use WillMaker to make your will or living trust.) You also can hire a California lawyer to create a POA for you, though the cost will be higher. Many lawyers will also include durable POAs as part of a more comprehensive estate plan alongside a will or living trust.

Whatever method you choose, the process of making the POA will include granting your agent all powers or selecting (and initialing), from a list, the specific powers you want your agent to have. For example, you might choose to grant your agent power over:

• real property transactions
• banking and other financial institution transactions
• retirement plan transactions
• stock and bond transactions
• business operating transactions
• benefits from social security, Medicare, Medicaid, or other governmental programs, and
• tax matters.

An optional section in the California statutory POA also allows you to further limit or extend your agent's powers if the standard list does not fit your goals.

Note that if you use California's statutory form, the power of attorney is durable (meaning that it remains effective after your incapacitation). In the statutory form, you'll find this language: "This power of attorney will continue to be effective even though I become incapacitated." If you make a non-statutory POA, the power of attorney is not durable unless it explicitly says so. (Cal. Prob. Code §§ 4124, 4404 (2025).)

2. Sign the POA in the Presence of a Notary Public or Two Witnesses

As mentioned above, you can't simply sign the document and call it a day. In California, you generally must have the POA notarized.

In some cases, you can choose to have it witnessed by two people instead, though it's best to at the very least have your POA notarized. (See above.) If you do choose witnesses, they must be over 18, and they can't be named as agents in your POA. (Cal. Prob. Code §§ 4121, 4122, 4402 (2025).)

3. Store the Original POA in a Safe Place

Once you have completed the POA, store the original in a safe place that your loved ones can easily access, and let them know where to find it. (It won't do much good locked away in a safe that no one can get into.) If you become incapacitated, your agent might need the original POA to act on your behalf.

4. Give a Copy to Your Agent

You should also give a copy of the power of attorney to your agent so that your agent is familiar with the contents of the document and can use it when needed.

5. File a Copy With the Land Records Office

If you initialed "real property transactions" as one of the powers you granted to your agent, you should also file a copy of your POA in the land records office (called the Office of the County Clerk-Recorder in California) of any county where you own real estate. This will allow the land records office to recognize your agent's authority if your agent ever needs to sell, mortgage, or transfer real estate for you.

6. Consider Giving a Copy to Financial Institutions

You can also give copies of your durable financial POA to banks or other institutions that your agent might need to deal with in the future. This step might eliminate some hassles for your agent if your agent ever needs to use the POA. Banks can sometimes be finicky about accepting POAs; see Can Banks Refuse a Power of Attorney? for more details.

Who Can Be Named an Agent (Attorney-in-Fact) in California?

Legally speaking, you can name any competent adult to serve as your agent. But you'll want to take into account certain practical considerations, such as the person's trustworthiness and geographical location. For more on choosing agents, see What Is a Power of Attorney. (Cal. Civ. Code §§ 39(b), 1556; Cal. Prob. Code § 4200 (2025).)

California allows you to appoint co-agents who are authorized to act at the same time, but it's usually advisable to stick to just one agent to minimize potential conflicts. However, you can name a "successor" agent—an alternate who will become your agent if your first choice is unavailable for any reason. A successor agent is always a good idea, as it creates a backup plan. (Cal. Prob. Code §§ 4202, 4203 (2025).)

When Does My Durable Financial Power of Attorney Take Effect?

Your POA should say when it takes effect. If you used California's statutory POA form, it will say, "UNLESS YOU DIRECT OTHERWISE ABOVE, THIS POWER OF ATTORNEY IS EFFECTIVE IMMEDIATELY AND WILL CONTINUE UNTIL IT IS REVOKED." The POA takes effect as soon as you've signed and notarized it.

It's possible to create a condition that must be satisfied before the POA becomes effective—such as a doctor declaring that you are incapacitated—but there are many reasons why this type of "springing" power of attorney is not usually advised. (Cal. Prob. Code §§ 4030, 4129, 4405 (2025).)

When Does My Financial Power of Attorney End?

Any power of attorney automatically ends at your death. It also ends if:

• Your POA document says when it will end. You can put an end date in your power of attorney.
• You revoke it. As long as you are mentally competent, you can revoke your document at any time.
• No agent is available. To reduce the likelihood of this happening, you can name a successor (alternate) agent in your document.
• A court invalidates your document. It's rare, but a court may declare your document invalid if it concludes that you were not mentally competent when you signed it, or that you were the victim of fraud or undue influence.

(Cal. Prob. Code §§ 4127, 4151, 4152, 4153 (2025).)

Additionally, in California, if your spouse is named as your agent in your POA, that designation automatically ends if you and your spouse divorce. However, your spouse's designation as agent will be revived if you remarry your spouse. To be clear, your ex-spouse's authority to act as your agent ends at divorce, but your POA will remain intact. So, if you named a successor agent, that person would become your agent. (Cal. Prob. Code § 4154 (2025).)

Do I Need a Lawyer to Make a Financial Power of Attorney in California?

You usually don't need a lawyer to prepare a durable power of attorney for finances because it's a simple and straightforward document. As discussed above, California's state government has even created a statutory form POA for people to complete on their own by filling in the blanks.
