What power of attorney actually lets you do
A power of attorney document gives one person (called the agent or attorney-in-fact) the legal right to act on behalf of another person (called the principal) in financial, medical, or legal matters. The scope of what you can do depends entirely on what the document says. A broad financial power of attorney might let you pay bills, sell property, or manage bank accounts. A limited one might restrict you to handling a single bank account or paying specific debts. A medical power of attorney lets you make healthcare decisions if the principal cannot. The document itself sets the boundaries — there is no universal power of attorney that does everything.
The person who signs the power of attorney document controls what powers you receive. They can give you sweeping authority or narrow it down to one task. They can revoke it at any time while they are still mentally capable of doing so. This is why the document matters more than the title: two financial powers of attorney can look identical but grant completely different rights depending on what the signer wrote into them.
Key Takeaways
- A power of attorney only grants the specific powers written into the document — there is no automatic set of rights that comes with the title.
- Financial powers of attorney typically cover banking, bill payment, property sales, and investment management, but only if the document explicitly names those powers.
- Medical powers of attorney let you make healthcare decisions, including end-of-life choices, but only if the principal has become unable to decide for themselves.
- The person who signed the power of attorney can revoke it at any time while they remain mentally capable, and they can change what powers you hold.
- You must act in the principal's best interest and keep their money and property separate from your own — misusing power of attorney is a crime.
Common financial powers in a standard document
Most financial powers of attorney include the right to access and manage bank accounts, pay bills from those accounts, deposit checks, and withdraw cash. They often cover real estate — you may be able to sell property, refinance a mortgage, or sign a lease on the principal's behalf. Investment accounts, retirement accounts, and brokerage accounts typically fall under financial power of attorney as well.
Tax matters are another common power. You might be authorized to file tax returns, claim refunds, or represent the principal before the IRS. Some documents give you the power to hire and fire professionals — accountants, lawyers, financial advisors — on the principal's behalf. Others let you make gifts, set up trusts, or change beneficiaries on insurance policies. The catch is that none of these powers exist unless the document specifically names them. A power of attorney that says "manage my bank accounts" does not automatically let you sell the house.
What medical power of attorney covers
A medical power of attorney (sometimes called a healthcare proxy or healthcare power of attorney) lets you make medical decisions when the principal cannot make them. This includes choosing doctors, authorizing surgery, deciding on medication, and choosing between treatment options. It covers decisions about hospitalization, nursing home placement, and rehabilitation facilities.
Medical power of attorney also typically includes the right to see medical records, talk to doctors, and get information about the principal's condition. In many states, it covers end-of-life decisions — whether to continue life support, pursue aggressive treatment, or move to comfort care. The document usually only takes effect when a doctor has determined that the principal lacks the mental capacity to make their own medical decisions. Until that point, the principal makes their own choices.
Powers you do not have, even with a broad document
Power of attorney does not let you change the principal's will, unless the document explicitly grants that power (and most do not). You cannot make gifts of the principal's money to yourself or others unless the document specifically authorizes gifts. You cannot take out loans in the principal's name, open new credit cards, or change the principal's insurance beneficiaries unless those powers are written in.
You also cannot use power of attorney to commit fraud, hide assets, or act against the principal's interests. If you do, you can be sued and face criminal charges. Power of attorney is not a blank check — it is a limited grant of authority that you must use only for the principal's benefit. If the principal is still mentally capable, they can override your decisions or revoke the document entirely.
The difference between durable and non-durable power of attorney
A durable power of attorney stays in effect even if the principal becomes mentally incapable. This is the type most people use for long-term planning, because it continues to work if the principal develops dementia, has a stroke, or becomes unable to manage their own affairs. A non-durable power of attorney ends automatically if the principal loses mental capacity. Non-durable documents are rare and usually used only for temporary situations — like authorizing someone to handle a real estate closing while you are out of the country.
Some powers of attorney are springing, meaning they only take effect when a specific event happens — usually when a doctor certifies that the principal can no longer make decisions. Others are when ready, meaning they work as soon as the principal signs them. The principal chooses which type they want when they create the document.
How to know what powers you actually have
Read the power of attorney document itself. It will list the specific powers granted, often in a checklist format. Look for sections labeled "Powers Granted," "Authority," or "Powers of Attorney." If the document is vague — for example, it says "manage my financial affairs" without listing specifics — you may have broad authority, but you should confirm this with a lawyer before taking major actions like selling property or making large gifts.
If you are unsure whether a specific action is covered, contact the person who signed the document and ask. If they are no longer capable of answering, consult a lawyer. Banks and financial institutions often have their own requirements and may ask to see the power of attorney document before letting you act. Some will only honor powers of attorney on their own forms. Getting a lawyer to review the document before you use it can prevent delays and disputes later.
Your duties as an agent under power of attorney
Once you accept power of attorney, you have a legal duty to act in the principal's best interest, not your own. This is called a fiduciary duty. You must keep the principal's money and property separate from your own. You cannot take loans from the principal's accounts, pay yourself without permission, or use their assets for your own benefit. You must keep records of all transactions and be ready to account for every dollar if the principal or their family asks.
You must act honestly and in good faith. If you discover that the principal is being abused or neglected, you may have a duty to report it. If you cannot or will not follow these rules, you should resign as agent and let someone else take over. Violating fiduciary duty can result in civil lawsuits and criminal charges for theft or fraud.
Frequently Asked Questions
Can I use power of attorney to take money out for myself?
Only if the document explicitly allows you to make gifts to yourself, and even then only if it is reasonable and in the principal's best interest. Most powers of attorney do not allow this. Taking money without permission is theft, even if you have power of attorney. Keep all transactions documented and separate from your own accounts.
Does power of attorney work after the principal dies?
No. Power of attorney ends when ready when the principal dies. After death, the estate is handled by an executor named in the will or by the court if there is no will. If you have power of attorney and the principal dies, you must stop using it and turn over all documents and assets to the executor or the court.
Can the principal take back power of attorney once they give it to me?
Yes, as long as they are still mentally capable. They can revoke it in writing at any time, and the revocation takes effect as soon as they sign it. Some states require the revocation to be notarized or delivered to you in person, but the principal has the right to end your authority whenever they choose.
What happens if I misuse power of attorney?
You can be sued by the principal or their family for any money or property you took wrongfully. You can also face criminal charges for theft, fraud, or elder abuse. Courts can order you to repay everything plus interest and penalties. If you are convicted, you may go to jail and lose your professional licenses.
Do I need a lawyer to understand what my power of attorney covers?
If the document is clear and lists specific powers, you may not need one. But if the language is vague, if you plan to take major actions like selling property, or if family members might dispute your authority, a lawyer can review the document and advise you on what you can legally do.
