What Powers You Give When You Sign

A power of attorney is a legal document that lets you give another person the right to make decisions or handle money and property on your behalf. The person you name — called your agent or attorney-in-fact — can then act as if they were you in specific situations. What they can actually do depends entirely on what you write into the document. You are not handing over all your rights; you are handing over only the ones you list.

The most common use is financial: paying bills, managing bank accounts, selling property, or handling taxes when you cannot do it yourself. But a power of attorney can also cover healthcare decisions, real estate transactions, business operations, or just one narrow task like signing a car title. The moment you sign, your agent can start using those powers. The moment the document expires or you revoke it, those powers stop.

Key Takeaways

  • A power of attorney only gives your agent the specific powers you write into the document — not a blank check to do whatever they want.
  • Financial powers let your agent pay bills, access bank accounts, sell property, or file taxes, but only if you grant those powers in writing.
  • Healthcare powers let your agent make medical decisions if you cannot, but only for the decisions you authorize.
  • Your agent must act in your best interest and keep records of what they do; you can revoke the document at any time while you are mentally capable.
  • A durable power of attorney stays in effect even if you become incapacitated, while a regular one ends if you lose mental capacity.

Financial Powers Your Agent Can Exercise

If you grant financial powers, your agent can handle money and property matters on your behalf. This typically includes accessing your bank accounts, writing checks, depositing money, transferring funds between accounts, and paying bills. They can also manage investments, buy or sell real estate, refinance loans, and handle insurance policies — but only the specific accounts and properties you name in the document.

Your agent can also file tax returns and handle tax matters with the IRS, manage your business if you own one, and make decisions about retirement accounts. Some people grant these powers because they are traveling long-term, others because they are ill or aging and want someone to manage finances if they become unable to. The key is that each power must be explicitly listed. If you do not mention real estate sales, your agent cannot sell your house, even if they have access to your bank account.

Your agent cannot use these powers for their own benefit without your permission — that is a legal violation called breach of fiduciary duty. They must keep records of what they spend, and you can ask to see those records at any time. If you suspect your agent is misusing the power, you can revoke the document when ready and pursue legal action.

Healthcare Powers and Medical Decisions

A healthcare power of attorney (sometimes called a healthcare proxy or medical power of attorney) lets your agent make medical decisions if you cannot communicate your wishes. This includes deciding on surgery, medication, end-of-life care, hospital admission, and which doctors treat you. Your agent steps in only when you are unable to make decisions yourself — if you are conscious and capable, you still make your own medical choices.

You can limit these powers to specific situations. For example, you might say your agent can decide on surgery but not on life support, or can make decisions only if you are in a coma. You can also write instructions about what you do and do not want — refusing certain treatments, requesting pain management, or specifying that you want to die at home rather than in a hospital. Your agent must follow those instructions, even if they disagree with them.

Healthcare powers do not let your agent access your medical records without your permission, though they can usually request them once they are acting as your agent. They also cannot override your own stated wishes if you are still able to communicate them. If you recover and can make decisions again, your agent's authority ends.

Limited Powers for Specific Tasks

You do not have to give broad powers. Many people create a power of attorney for one specific task: signing a car title, closing a real estate deal, depositing a check, or handling a single bank account. This is called a limited or special power of attorney, and it is useful when you need someone to act for you in one situation but do not want to give them broader authority.

For example, if you are selling a house but will be out of the country at closing, you can give your agent power to sign the deed and closing documents — nothing else. Or if you need someone to deposit a settlement check into your account while you recover from surgery, you can limit their power to that one deposit. Limited powers are often easier to get notarized and carry less risk because the agent cannot act outside the narrow scope you set.

What Your Agent Cannot Do

A power of attorney does not let your agent change your will, create a new will, or make decisions about your estate after you die. Those powers belong to your executor, named in your will. Your agent also cannot vote on your behalf in elections, adopt children, marry or divorce on your behalf, or make decisions about guardianship of your minor children.

Your agent cannot use the power of attorney to benefit themselves unless you explicitly allow it. They cannot take out loans in your name, give away your money to themselves or others, or use your assets for their own purposes. If they do, that is fraud and breach of trust, and you can sue them and report them to law enforcement. Some states also require your agent to post a bond — a kind of insurance — before they can act, depending on what powers you grant.

Your agent also cannot act after the power of attorney expires or is revoked. If you create a regular (non-durable) power of attorney and then lose mental capacity, the document automatically ends and your agent loses all authority. At that point, only a court-appointed guardian can make decisions for you.

Durable Versus Non-Durable Powers

A durable power of attorney stays in effect even if you become mentally incapacitated — unable to make decisions or communicate. This is the type most people use, because the whole point is often to have someone ready to act if you become ill or unable to manage your own affairs. The document must explicitly say it is durable, usually with language like "this power of attorney shall not be affected by my subsequent incapacity."

A non-durable power of attorney ends automatically if you lose mental capacity. This type is useful for temporary situations — like giving someone power to handle finances while you are traveling — but it does not protect you if you later become unable to make decisions. If you do not specify, most states assume you meant a non-durable power of attorney, so you have to ask for durable if that is what you want.

Some people also create a springing power of attorney, which does not take effect until a specific event happens — usually when a doctor certifies that you are incapacitated. This lets you keep control until you actually need someone to act for you. However, springing powers can create delays because your agent has to prove the triggering event happened before they can act.

How Your Agent Must Act

Your agent has a legal duty called a fiduciary duty, which means they must act in your best interest, not their own. They must keep your money and property separate from theirs, keep records of all transactions, and be honest about what they do. If you ask, they must show you receipts, bank statements, and a full accounting of how they spent your money.

Your agent cannot use the power of attorney to make gifts to themselves unless you specifically allow it in the document. Even then, some states limit how much they can give themselves. Your agent also cannot take out loans in your name, pledge your property as collateral, or change beneficiaries on your insurance or retirement accounts — unless you explicitly grant those powers.

If your agent violates these duties, you can revoke the power of attorney, sue them for damages, and report them to law enforcement. Family members or other interested parties can also ask a court to remove your agent if they believe the agent is abusing the power.

How to Revoke or Change a Power of Attorney

You can revoke a power of attorney at any time, as long as you are mentally capable of understanding what you are doing. You do not need your agent's permission. To revoke, you typically sign a written revocation document, have it notarized, and deliver copies to your agent, your banks, your healthcare providers, and anyone else who might rely on the power of attorney. Some states also let you revoke by destroying the original document or straightforward telling your agent in writing that the power is revoked.

If you want to change the powers — for example, removing real estate authority but keeping financial authority — you can create a new power of attorney that replaces the old one. Make sure to revoke the old document in writing so there is no confusion about which one is current. If you have already given copies to banks or other institutions, notify them of the change.

If you become mentally incapacitated and did not create a durable power of attorney, your family will have to go to court to have a guardian appointed. This is more expensive, slower, and gives the court — not your chosen person — the power to decide what happens. That is why creating a power of attorney while you are still able is much simpler than waiting.

Frequently Asked Questions

Can my agent use the power of attorney after I die?

No. A power of attorney ends the moment you die. After that, only your executor (named in your will) or your heirs have authority over your estate. Your agent must stop using the power of attorney when ready and return the original document.

What happens if my agent dies or becomes unable to act?

The power of attorney ends. You can name a successor agent in the original document so that if your first choice dies or refuses to act, a second person automatically takes over. If you did not name a successor and your agent dies, you will need to create a new power of attorney with a different agent.

Does my agent have to tell me what they are doing with my money?

Yes. Your agent must keep records and show them to you if you ask. They cannot hide transactions or refuse to account for how they spent your money. If they will not provide records, that is a sign of abuse and you should revoke the power of attorney and consult a lawyer.

Can I give power of attorney to more than one person?

Yes. You can name multiple agents and decide whether they must act together (both must agree) or separately (either one can act alone). Acting together is safer because it requires agreement, but it is slower. Acting separately is faster but carries more risk if one agent acts without the other's knowledge.

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

You do not legally need one, but a lawyer can make sure the document is valid in your state, covers all the powers you want, and is properly worded to avoid confusion. Many states have specific language requirements for durable powers of attorney, and a mistake can make the document invalid. A lawyer typically charges $200 to $500 for a straightforward power of attorney.
