What a power of attorney document does and how to start one

A power of attorney is a legal document that lets you give someone else the authority to make decisions or handle money and property on your behalf. You are the principal — the person giving the power. The person you choose is the agent or attorney-in-fact (the title does not mean they are a lawyer). Once signed and notarized, the document takes effect when ready, unless you specify a later date or make it durable — meaning it stays valid even if you become unable to make decisions yourself.

The process has four main steps: decide what powers you want to give, choose who will hold them, fill out the correct form for your state, and have it notarized. You do not need a lawyer to create one, though some people hire one to make sure the language fits their situation. The cost ranges from nothing (if you use a free state form and a notary at your bank) to several hundred dollars (if you hire an attorney). Most people can handle this themselves in an afternoon.

Key Takeaways

  • You must be of sound mind and at least 18 years old to create a power of attorney, and you can revoke it at any time by destroying the document and notifying your agent in writing.
  • Each state has its own form and rules; your state's bar association or secretary of state website publishes the official version, and using the wrong state's form can make the document invalid out of state.
  • A durable power of attorney stays valid if you become incapacitated, while a regular one ends; most people choose durable to cover the possibility they cannot manage their own affairs later.
  • Your agent can be a family member, friend, or professional, but they have a legal duty to act in your best interest and keep your money separate from theirs.
  • Notarization is required in all states; you can get this done at a bank, notary public office, or some law firms, usually for $5 to $15.

Decide what powers you want to give your agent

A power of attorney can be broad or narrow. A general power of attorney lets your agent handle almost any financial or legal matter — selling property, managing bank accounts, paying bills, filing taxes. A limited power of attorney restricts your agent to specific tasks, like selling one piece of property or managing one bank account. Some people create a healthcare power of attorney (also called a healthcare proxy or medical power of attorney) that covers only medical decisions, not money.

Most state forms list specific powers as checkboxes: real estate, bank accounts, stocks and bonds, taxes, business operations, insurance, gifts. You check the ones you want your agent to have. If you want your agent to have all powers, most forms have a single box for that. Be specific about what you actually need — if you only want someone to pay your bills while you travel, a limited power of attorney for banking is safer than giving them authority over everything.

Choose your agent and decide when the power takes effect

Your agent should be someone you trust completely, because they have a legal duty to act in your interest but you will not always be watching. Many people choose a spouse, adult child, or close friend. Some choose a professional — a bank trust department, a certified financial planner, or an attorney — if they do not have family they trust or if the finances are complex. You can name a backup agent (called a successor agent) who steps in if your first choice dies, becomes unable to serve, or refuses.

Decide whether the power takes effect when ready or only if you become incapacitated. An when ready power of attorney is active as soon as you sign it — useful if you want someone to handle your affairs while you are traveling or ill but still able to make decisions. A springing power of attorney activates only when a doctor certifies that you cannot make decisions yourself. Springing powers are less common now because they can create delays and disputes over whether you are actually incapacitated; most people choose durable when ready powers instead, trusting their agent to use the power only when needed.

Get the correct form for your state

Every state has its own power of attorney form, and using the wrong state's form can make the document invalid outside that state. Find your state's official form through your state bar association website or your secretary of state's office. Many states publish free forms on their websites. Some states have separate forms for general, limited, and healthcare powers of attorney; others combine them into one form with checkboxes.

Fill out the form completely. You will need to write in your name, your agent's name and address, the powers you are granting, and the date. Some forms ask whether the power is durable (stays valid if you become incapacitated) — check yes unless you have a specific reason not to. Do not leave blanks; if a section does not explore, write "N/A" so it is clear you did not skip it by accident. Read the entire form before you sign; some states require specific language about what durable means, and the form will have it built in.

Have the document notarized

All states require a notary public to witness your signature. A notary is not a lawyer — they are someone trained to verify that you are who you say you are and that you are signing of your own free will. You can find a notary at a bank (often free if you have an account), a notary public office (usually $5 to $15), a law firm, or sometimes a UPS Store or pharmacy. Call ahead to confirm they are available and what they charge.

Bring a photo ID and the unsigned power of attorney form. The notary will watch you sign, check your ID, and stamp the document with their seal and signature. Some states also require a witness — a second person who watches you sign and is not your agent or related to you. Check your state's form to see if witnesses are required; if they are, bring two people who meet the requirements. The whole process takes about 10 minutes.

Store the original and give copies to people who need them

Keep the original signed, notarized document in a safe place — a safe deposit box, a home safe, or with your attorney. Make several photocopies. Give a copy to your agent so they know what powers they have. Give copies to your bank, investment firm, or any institution your agent might need to contact on your behalf; some institutions will not accept a copy and will ask for the original, so ask first.

Tell your agent where the original is kept and how to access it if something happens to you. If you become incapacitated, your agent will need to present the document to prove they have authority. Some institutions keep copies on file; others require a new copy each time. If you move to a different state or your situation changes significantly, you may need to create a new power of attorney that complies with your new state's rules.

Revoke or change a power of attorney

You can revoke (cancel) a power of attorney at any time as long as you are of sound mind. Revoke it by destroying the original document and all copies, or by creating a written revocation statement and having it notarized. Give written notice to your agent and to any institution that has a copy. If you create a new power of attorney, it typically revokes any earlier one, but to be safe, revoke the old one explicitly in writing.

If you want to change only some powers or add new ones, you can amend the document, though it is often simpler to revoke the old one and create a new one. Keep a record of when you revoked it and who you notified, in case questions come up later about whether your agent had authority at a particular time.

Frequently Asked Questions

Do I need a lawyer to create a power of attorney?

No. You can use your state's free form, fill it out yourself, and have it notarized for $5 to $15. A lawyer is helpful if your finances are complex, you have concerns about your agent's judgment, or you want to add unusual conditions, but most straightforward situations do not require one.

What happens if I become incapacitated and do not have a power of attorney?

Your family will have to go to court and ask a judge to appoint a conservator or guardian to manage your affairs. This is more expensive, slower, and gives the court control over who manages your money instead of you choosing. A durable power of attorney prevents this.

Can my agent use the power of attorney for their own benefit?

No. Your agent has a legal duty called a fiduciary duty to act in your interest, not theirs. They cannot take money for themselves, give themselves gifts, or use your property without your permission. If they do, you or your heirs can sue them to recover the money.

Will my power of attorney work in another state?

It may, but it is not may provide. Some states honor powers of attorney from other states if they are notarized and follow basic rules. Others require the document to comply with their own state's law. If you spend significant time in another state, ask an attorney there whether your document will be accepted, or create a separate power of attorney for that state.

What is the difference between a power of attorney and a will?

A power of attorney lets someone manage your affairs while you are alive. A will takes effect after you die and says who gets your property. You need both: the power of attorney covers your lifetime, and the will covers what happens to your estate after you pass away.
