A power of attorney lets someone else handle your money and property decisions when you cannot or choose not to
A power of attorney is a legal document that gives another person the authority to act on your behalf. That person — called your agent or attorney-in-fact — can sign documents, move money, sell property, or make other decisions you would normally make yourself. You remain in control of what powers you grant and when they take effect. The agent has no authority beyond what the document specifies.
The document does not make you lose your own authority. You can still sign checks, sell your house, or change your mind about decisions while you are able to do so. The power of attorney straightforward adds another person who can act in your place, usually when you are unavailable, incapacitated, or prefer to delegate the task.
Key Takeaways
- A power of attorney names someone to handle your financial or medical decisions, and you decide exactly which powers they receive.
- The document takes effect either when ready or only if you become unable to manage your own affairs, depending on how you write it.
- Your agent can only act within the powers you grant — they cannot sell your house if the document limits them to banking decisions.
- You can revoke the power of attorney at any time while you are mentally capable of doing so.
- Different states have different forms and rules, so the document must follow your state's law to be valid.
Financial power of attorney versus medical power of attorney
A financial power of attorney covers money and property. Your agent can pay bills, deposit checks, access bank accounts, buy or sell real estate, file taxes, manage investments, or handle insurance claims — but only the tasks you list in the document. You might give broad powers or narrow ones: some people authorize their agent to do anything financial, while others limit them to paying specific bills.
A medical power of attorney (also called a healthcare power of attorney or healthcare proxy) covers medical decisions. Your agent can consent to treatment, refuse treatment, access medical records, choose a hospital, or make end-of-life decisions if you cannot communicate your wishes. This document does not take effect unless you are unconscious, mentally incapacitated, or otherwise unable to make decisions yourself.
You can name the same person as your agent for both documents, or different people. Many people choose a spouse or adult child for financial matters and a different family member for medical decisions, depending on who they trust most in each area.
when ready power of attorney versus springing power of attorney
An when ready power of attorney takes effect as soon as you sign it. Your agent can start acting on your behalf right away, even if you are healthy and fully capable. This is useful if you travel frequently, run a business, or straightforward want to delegate routine tasks like bill-paying. You remain able to act on your own behalf at the same time — both you and your agent can sign checks or access accounts.
A springing power of attorney takes effect only when a specific event occurs, usually your incapacity. The document sits dormant until a doctor certifies that you can no longer manage your affairs, or until you become unconscious. At that point, your agent's authority "springs" into effect. This approach appeals to people who want someone ready to step in if needed but do not want to hand over authority while they are still capable.
Springing powers of attorney are more complicated to set up and sometimes harder for banks and other institutions to accept, because they have to verify that the triggering event actually happened. when ready powers of attorney are simpler and more widely recognized, but they require you to trust your agent completely from day one.
What your agent can and cannot do
Your agent can only act within the powers you grant in writing. If your document says your agent can pay bills and access bank accounts, they cannot sell your house, change your will, or make medical decisions. The limits are strict — institutions like banks will refuse to honor requests that fall outside the document's scope.
Your agent cannot use the power of attorney to benefit themselves unless you explicitly allow it. They have a legal duty called a fiduciary duty to act in your interest, not their own. If your agent steals money or uses your assets for personal gain, you can sue them and they can face criminal charges. Some states require your agent to keep records of all transactions and report to you or to a court.
Your agent cannot change your will, make gifts on your behalf (unless you specifically authorize it), vote in your place, or make decisions about your care after you die. A power of attorney ends when you die — at that point, your will and your executor take over.
How to create a power of attorney
Each state has its own rules about what makes a power of attorney valid. Most states require the document to be in writing, signed by you in front of a notary public, and sometimes witnessed by other people. Some states have specific forms you should use, while others allow you to write your own as long as it meets the legal requirements.
You can read a template from your state bar association, your state's court website, or a legal document service. Many people use online legal services like LegalZoom or Nolo, which generate state-specific forms for a fee. If your situation is complex — if you own a business, have significant assets, or want to set conditions on your agent's authority — an attorney can draft a custom document and make sure it is airtight.
Once you sign the document, give copies to your agent, your bank, your doctor's office, and anyone else who might need to see it. Keep the original in a safe place. Tell your agent where to find it if something happens to you.
Revoking a power of attorney
You can cancel a power of attorney at any time while you are mentally capable of doing so. Write a revocation letter stating that you are canceling the document, sign it, have it notarized, and deliver copies to your agent, your bank, and anyone else who has a copy of the original. Some states have a specific revocation form you should use.
A power of attorney also ends automatically if you die, if you become mentally incapacitated (unless it is a durable power of attorney), or on the date you specify in the document. A durable power of attorney continues even after you become incapacitated, which is why most people use durable documents — otherwise the power of attorney becomes useless exactly when you need it most.
Why people create a power of attorney
Some people create a power of attorney because they are about to have surgery or a medical procedure and want someone to handle their affairs if recovery takes longer than expected. Others are aging and want to plan ahead in case they develop dementia or another condition that affects their judgment. Business owners often give a spouse or partner power of attorney to sign contracts and access accounts while they are traveling.
A power of attorney is not the same as a will. A will only takes effect after you die and only covers property you own at death. A power of attorney takes effect while you are alive and covers decisions you make during your lifetime. Many people have both — a will to say what happens to their property after death, and a power of attorney to say who makes decisions if they become unable to do so while alive.
Frequently Asked Questions
Can my agent use my power of attorney to give themselves money or property?
Not without your permission. Your agent has a legal duty to act in your interest, not their own. If you want to allow gifts to your agent, you must say so explicitly in the document. If your agent takes money or property without permission, you can sue them and they can face criminal charges for theft or fraud.
What happens to my power of attorney if I become mentally incapacitated?
It depends on whether you created a durable power of attorney. A durable document continues even after you become incapacitated, which is why most people use them. A non-durable power of attorney ends if you lose mental capacity. If you do not have a durable power of attorney and you become incapacitated, your family may have to go to court to get a conservatorship or guardianship, which is more expensive and less private.
Can I name more than one agent in a power of attorney?
Yes. You can name two or more agents and decide whether they must act together or can act separately. If they must act together, both have to sign every document. If they can act separately, either one can act alone. Acting separately is simpler but requires you to trust both agents completely.
Does my agent have to tell me what they are doing with my money?
That depends on your state and what your document says. Many states require agents to keep records and report to you or to a court. Even if your state does not require it, you can ask your agent for an accounting at any time while you are capable of doing so. If you suspect your agent is misusing your money, you can revoke the power of attorney and ask a court to investigate.
Is a power of attorney the same as a guardianship?
No. A power of attorney is something you create yourself, giving authority to someone you choose. A guardianship is a court order that a judge imposes when someone is unable to manage their own affairs and has not created a power of attorney. Guardianship is more restrictive, more expensive, and more public. Creating a power of attorney while you are still capable lets you avoid guardianship.
