A power of attorney is a legal document that lets you give someone else permission to make decisions or sign documents on your behalf
When you sign a power of attorney, you are naming another person—called your agent or attorney-in-fact—to act for you. That person can then sign checks, pay bills, manage bank accounts, sell property, or handle other tasks you specify, without needing you to sign every document yourself. You stay in control: you decide exactly what powers you give them, when those powers start, and when they end.
The document is not about going to court or hiring a lawyer. It is straightforward a written agreement that tells banks, government offices, and other organizations that your agent has your permission to act. Different types of power of attorney give different amounts of power, and they work in different situations—some only while you are alive, some only if you become unable to make decisions, some both.
Key Takeaways
- A power of attorney names someone to sign documents and make decisions for you, and you control exactly what powers they have.
- A durable power of attorney stays in effect even if you become mentally unable to make decisions, while a non-durable one ends if you lose capacity.
- A healthcare power of attorney is separate and only covers medical decisions; a financial one covers money and property.
- You can revoke a power of attorney at any time by signing a written revocation and notifying the agent and any organizations that have a copy.
- The document must be signed and notarized in most states, and some organizations may require their own form instead of yours.
Durable versus non-durable: what happens if you become unable to decide
A non-durable power of attorney ends automatically if you become mentally unable to make decisions—if you have a stroke, develop dementia, or fall into a coma. This type is useful for a short-term task: you might give someone power of attorney to sell your car while you are traveling, and that power disappears once the sale closes or once you return home.
A durable power of attorney stays in effect even if you lose the ability to make decisions. This is the type most people use for long-term planning. If you become unable to manage your finances or sign documents, your agent can still act on your behalf. Some durable powers of attorney start right away; others only "spring" into effect if a doctor confirms you are unable to decide—you choose which version you want.
Financial power of attorney versus healthcare power of attorney
A financial power of attorney covers money and property: paying bills, managing bank accounts, buying or selling real estate, filing taxes, and managing investments. Your agent can do whatever you authorize them to do with your finances.
A healthcare power of attorney (sometimes called a healthcare proxy or medical power of attorney) is completely separate and covers medical decisions only. It lets your agent choose doctors, approve or refuse treatment, and make end-of-life decisions if you cannot. You need both documents if you want someone to handle both your money and your medical care. One document does not cover the other.
What your agent can and cannot do
Your agent can only do what the document says they can do. You might give them power to pay bills and manage your bank account, but not to change your will, give away your property, or make medical decisions. You write the limits into the document itself.
Your agent cannot use the power of attorney for their own benefit unless you explicitly allow it. If they do—if they transfer money to themselves, sell your property to themselves at a low price, or use your accounts to pay their own debts—they are breaking the law and can be sued. They have a legal duty called a fiduciary duty to act in your interest, not theirs.
Your agent also cannot change your will, make or change a trust, or vote on your behalf using a power of attorney. Those require separate documents or are not allowed at all. Some states also restrict agents from making gifts or changing beneficiaries on retirement accounts unless you specifically authorize it in writing.
How to create a power of attorney
You can write a power of attorney yourself using a template from your state bar association, a legal website, or a form book—many are free or cost under $20. The document must name you (the person giving the power), name your agent, describe the powers you are giving, and be signed and dated. In most states, it must also be notarized: a notary public watches you sign it and stamps it to confirm you signed it willingly and knew what you were signing.
You can also hire a lawyer to draft one. This costs more—typically $200 to $500 for a financial power of attorney, more if you have complex finances—but a lawyer can make sure the document fits your exact situation and will be accepted by banks and government offices in your state.
Some organizations—banks, brokerages, insurance companies—have their own power of attorney forms and may refuse to accept yours. Ask them in advance whether they have a form they require. If they do, you may need to sign both their form and yours.
When your power of attorney takes effect and how to revoke it
A power of attorney takes effect as soon as you sign it, unless you write in the document that it should only start later (a "springing" power of attorney). You should give a copy to your agent and to any organization that will need it—your bank, your brokerage, your insurance company. Keep the original in a safe place.
You can revoke a power of attorney at any time, as long as you are mentally able to make decisions. Sign a written revocation, keep a copy for yourself, and send copies to your agent and to any organization that has a copy of the original. Some organizations may ask you to sign their own revocation form. If your agent dies or you want to name a new agent, you must revoke the old power of attorney and sign a new one.
A power of attorney also ends when you die. Your agent cannot use it after your death; your will and your estate take over instead.
What happens if you do not have a power of attorney
If you become unable to make decisions and you have not signed a power of attorney, your family cannot straightforward step in and manage your finances or make medical decisions. They would have to go to court and ask a judge to appoint a guardian or conservator—a legal process that takes weeks or months, costs money in court fees, and gives a judge control over your affairs instead of your family.
A power of attorney lets you choose who you trust and avoid court. It is one of the simplest and cheapest ways to plan for the possibility that you might not be able to manage your own affairs someday.
Frequently Asked Questions
Can my agent use the power of attorney after I die?
No. A power of attorney ends when you die. Your agent cannot use it to pay bills, access accounts, or make any decisions after your death. Your will, your trust, and your estate take over instead. Your executor or trustee handles those tasks.
What if my agent does not want the job anymore?
Your agent can resign by notifying you in writing. You should then sign a new power of attorney naming a different agent. If your agent resigns and you do not name a replacement, the power of attorney becomes useless—no one can act for you.
Do I need a lawyer to make a power of attorney?
No, but it depends on your situation. A straightforward financial power of attorney can be made using a free template and notarized at a bank or notary office. If your finances are complex, you own real estate in multiple states, or you want a healthcare power of attorney too, a lawyer can make sure the document is correct and will be accepted everywhere you need it.
Can I give power of attorney to more than one person?
Yes. You can name two or more agents, and they can act together (both must sign) or separately (either one can act alone). Acting together is safer but slower; acting separately is faster but riskier if the agents disagree. Most people name one primary agent and one backup in case the first cannot act.
What if I want to limit what my agent can do?
Write the limits into the document. You might say your agent can pay bills and manage your checking account but cannot sell your house, or can only spend up to $5,000 without asking you first. The more specific you are, the clearer it is what your agent can and cannot do.
