What Powers You Give When You Sign

A power of attorney is a legal document that lets you give another person the right to act on your behalf in financial, medical, or legal matters. The person you name — called your agent or attorney-in-fact — can only do what you explicitly permit in the document. You control the scope: you might give them authority to manage your bank account, sell property, make healthcare decisions, or handle all three. The document is not a blank check. It lists specific powers, and your agent cannot exceed them.

The powers you grant depend entirely on what you write into the document. Some people create a narrow power of attorney that covers only one task — for example, signing a deed for a house sale while you are out of the country. Others create a broad one that covers nearly all financial decisions. You decide the boundaries, and those boundaries are legally binding on your agent.

Key Takeaways

  • Your agent can only exercise the specific powers you list in the document — they cannot act beyond those boundaries.
  • Financial powers typically include managing bank accounts, paying bills, selling property, and handling investments, but only if you authorize each one.
  • Healthcare powers let your agent make medical decisions if you cannot, but only for the types of decisions you permit.
  • A durable power of attorney remains valid if you become incapacitated, while a standard one ends if you lose mental capacity.
  • Your agent has a legal duty to act in your best interest and must keep records of what they do with your money or property.

Financial Powers Your Agent Can Exercise

If you grant financial powers, your agent might be able to access your bank accounts, write checks, transfer money, and pay your bills. They can deposit checks in your name, manage your investments, and handle tax documents. However, you must specifically authorize each category. A power of attorney that says "manage my finances" is vague; a strong one lists "access checking and savings accounts at [bank name]" and "pay household expenses from those accounts."

Real estate is a common area where people grant power of attorney. Your agent can sign deeds, handle rental property matters, refinance mortgages, or sell land — but only if the document explicitly permits real estate transactions. Some people limit this to a single property or a single transaction. Others grant broad authority over all real property they own. The document must be clear about what property is included and whether your agent can borrow money against it.

Your agent cannot use these powers for their own benefit unless you specifically allow it. If they do, they can be sued and forced to repay what they took. They must keep records of transactions and show you or your family what they spent your money on. This duty to act honestly is called a fiduciary duty, and it is built into the law regardless of what the document says.

Healthcare 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 or decide for yourself. This includes choosing doctors, approving surgery, deciding on medication, and choosing whether to continue life support. The scope depends on what you authorize. You might limit it to end-of-life decisions only, or you might grant broad authority over all medical choices.

Your agent must follow any written instructions you leave, such as a living will or advance directive. If you have written that you do not want life support, your agent cannot override that choice. They must act according to your known wishes, not their own preferences. If your wishes are unknown, they must act in your best interest as they reasonably understand it.

Healthcare powers do not take effect unless you are unable to make decisions yourself. Your doctor determines whether you have that capacity. Until then, you remain in charge of your own medical care, and your agent has no authority to act.

What Your Agent Cannot Do

Your agent cannot change your will, even if you grant them broad financial powers. They cannot make gifts of your money or property unless you specifically permit it in the document. They cannot vote on your behalf in elections. They cannot make decisions about your children or dependents unless the document explicitly grants guardianship or custodial powers — and even then, only a court can appoint a guardian.

Your agent cannot use the power of attorney to benefit themselves unless you allow it. For example, if you grant them power over your bank account, they cannot transfer money to their own account without your permission. If they do, it is theft, and you or your heirs can sue them. Some people do authorize their agent to pay themselves a fee for their work, but this must be written into the document.

Your agent cannot act after you die. Once you pass away, the power of attorney ends, and your estate is handled by your will or by the laws of your state. Your agent has no authority over your property after death unless you name them as executor in your will.

Durable Versus Non-Durable Powers

A durable power of attorney remains in effect even if you become mentally incapacitated or unable to communicate. This is the type most people create, because it protects them if they develop dementia, have a stroke, or fall into a coma. Without durability language, the power of attorney automatically ends if you lose mental capacity — which is often the exact moment you need it most.

A non-durable power of attorney ends if you become incapacitated. This type is useful for temporary situations — for example, if you are traveling and need someone to sign documents on your behalf, but you want that authority to end when you return. Once you lose capacity, a non-durable power of attorney is worthless, and your family would have to go to court to get a conservator or guardian appointed to manage your affairs.

The difference is usually just a few words in the document. Your attorney or the form you use will specify whether it is durable. If you do not want it to be durable, you must say so explicitly. Most states assume you want durability unless you state otherwise.

When Your Agent's Powers Start and Stop

A power of attorney can take effect when ready when you sign it, or it can be springing — meaning it only takes effect when a specific event happens, usually when a doctor certifies that you are incapacitated. A springing power of attorney gives you more control: your agent cannot act unless the triggering event occurs. However, it can create delays and complications, because your agent must first prove that you are incapacitated before they can act.

Your power of attorney ends when you revoke it — that is, when you formally cancel it in writing. It also ends when you die, when you become mentally incapacitated (if it is not durable), or on a date you specify in the document. Some people set an expiration date, such as five years from the signing date. Others leave it open-ended, so it remains valid until they revoke it or die.

You can revoke a power of attorney at any time, as long as you are mentally capable of understanding what you are doing. You must notify your agent in writing and inform any banks, brokers, or other institutions that have been relying on it. straightforward destroying the document is not enough; you must formally revoke it.

How to Create a Power of Attorney

You can create a power of attorney using a form from your state's bar association, a legal document service, or an attorney. The document must be signed and, in most states, notarized. Some states require witnesses as well. The specific requirements vary by state and by the type of power of attorney — healthcare powers often have different rules than financial ones.

An attorney can help you understand what powers you actually need and draft language that is clear and legally sound. This costs money, but it reduces the risk of disputes later. If your situation is straightforward — for example, you just need someone to manage your bank account — a state form may be sufficient. If your finances are complex or you have specific concerns, an attorney is worth the cost.

Once the document is signed and notarized, give a copy to your agent and to any institution that will need to see it — your bank, your broker, your healthcare provider. Keep the original in a safe place and tell your family where it is. If your agent needs to act after you become incapacitated, they will need to produce the original or a certified copy.

Frequently Asked Questions

Can my agent spend my money on themselves?

Only if you explicitly permit it in the document. Otherwise, they are breaking the law. Even if you allow it, they must keep records and account for what they spent. If you do not authorize self-dealing, your agent can be sued by you or your heirs for any money they took.

What happens if my agent abuses the power of attorney?

You can revoke it when ready if you are still mentally capable. If you are incapacitated, your family can petition a court to remove your agent and appoint a conservator or guardian. You or your heirs can also sue your agent for any money or property they misused. Banks and institutions can be held liable if they knowingly helped your agent commit fraud.

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

Yes. Your agent has a legal duty to keep records and account for their actions. You can ask them to show you bank statements, receipts, and a summary of transactions. If they refuse, that is a sign of abuse, and you should consult an attorney.

Can I have more than one agent?

Yes. You can name co-agents who act together, or successor agents who take over if the first agent dies or becomes unable to serve. You can also name different agents for different powers — one person to manage your finances and another to make healthcare decisions. The document must be clear about how multiple agents work together.

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

A power of attorney gives someone authority to act on your behalf while you are alive. A living will is a document that tells doctors what kind of medical care you want if you become unable to decide — it does not give anyone power to act, it just records your wishes. Many people create both.
