What you can access depends on the type of power of attorney and what the document actually says
A power of attorney does not automatically give you access to someone's bank account. The document has to specifically grant that power, and the bank has to recognize it as valid. Even then, the bank may require you to jump through additional steps — some banks have their own forms, some want a certified copy, and some will not honor a power of attorney at all for certain account types. You need to know what your document says, what the bank requires, and whether the account holder is still alive, because the rules change dramatically at death.
The three most common types of power of attorney are general (covers finances and property), limited (covers only specific things you list), and healthcare (covers medical decisions only). A healthcare power of attorney gives you zero access to bank accounts. A general power of attorney usually includes bank access unless it explicitly excludes it. A limited power of attorney only gives you the powers written into it — so if it says "pay bills from the checking account," you can do that, but you cannot withdraw cash or move money to investments.
The document also has to say whether it is durable or not. A durable power of attorney stays valid even if the account holder becomes mentally incapacitated. A non-durable one ends the moment they lose capacity. If the account holder is already incapacitated and the document is not durable, the power of attorney is worthless — you will need a conservatorship or guardianship instead, which requires court involvement.
Key Takeaways
- The power of attorney document must specifically grant financial powers to include bank account access; healthcare powers of attorney do not cover bank accounts.
- Banks have their own verification requirements and may refuse to honor a power of attorney even if it is valid under state law, so you must contact the bank directly before assuming you have access.
- A durable power of attorney remains valid if the account holder becomes incapacitated; a non-durable one does not, and you will need court intervention instead.
- Once the account holder dies, the power of attorney becomes void when ready, and you must go through probate or use a payable-on-death designation to access funds.
- Some banks require their own power of attorney form or a certified copy of your document, and some will not honor a power of attorney for joint accounts, trust accounts, or retirement accounts.
How to present the power of attorney to a bank
Start by calling the bank's main customer service line and asking for the department that handles power of attorney requests. Do not go to a branch — branch staff often do not know the bank's actual rules and will give you wrong information. The central department will tell you exactly what they need: usually a certified copy of the power of attorney, a government-issued ID for you, and sometimes a form the bank wants you to fill out.
A certified copy means a copy that has been stamped and signed by a notary public or by the court that issued the document. If you only have the original, you can take it to a notary and pay a small fee (usually $5 to $15 per page) to get certified copies made. Some banks will accept a photocopy if you also bring the original to verify, but do not assume this — ask first.
Many large banks have their own power of attorney form they want you to complete instead of or in addition to your state's form. This is legal, and you have to do it if you want access. The form usually asks you to list the account numbers you want the power of attorney to cover, confirm that you are acting in the account holder's best interest, and sign under penalty of perjury. Filling it out takes 10 to 15 minutes.
Once you submit everything, the bank will verify the document and either grant you access or tell you why they will not. This usually takes three to ten business days. Some banks will call the account holder to confirm they authorized this, especially if the account holder is still alive and mentally present. This is normal and protects against fraud.
What you can and cannot do once you have access
Your powers are limited to what the document says. If it grants you "full financial power of attorney," you can typically withdraw money, transfer funds, pay bills, deposit checks, open new accounts in the account holder's name, and close accounts. If it is limited to "paying household bills," you can only do that — you cannot move money to your own account or make investments.
You must act in the account holder's best interest, not your own. This is a legal duty called a fiduciary duty. If you use the account for personal expenses without permission, that is theft, and the account holder or their heirs can sue you and report you to police. Keep records of every transaction. If you are paying bills, keep the receipts. If you are withdrawing cash, write down what it was for. If the account holder is still alive and mentally capable, they can revoke the power of attorney at any time, and they have the right to see what you have done with their money.
Some account types are off-limits even with a power of attorney. Retirement accounts (IRAs, 401(k)s) usually cannot be accessed by a power of attorney — the account holder has to name a beneficiary or update their will. Joint accounts sometimes cannot be accessed by a power of attorney if the bank treats them as owned equally by both people. Trust accounts belong to the trust, not the individual, so a power of attorney over the individual does not touch the trust account. Ask the bank which accounts are covered by the power of attorney before you assume you can access them.
What happens if the account holder becomes incapacitated
If your power of attorney is durable, it stays valid. You can continue to manage the account exactly as before. The bank may ask you to provide a doctor's letter confirming incapacity, or they may not — it depends on the bank. Some banks are cautious and want proof; others trust the document as written.
If your power of attorney is not durable, it becomes worthless the moment the account holder loses mental capacity. You cannot access the account, and the account holder cannot authorize you to do so because they are incapacitated. Your only option is to petition the court for a conservatorship (if you want to manage money) or a guardianship (if you want to make all decisions). This requires filing paperwork with the probate court, paying court fees (usually $200 to $500), and sometimes attending a hearing. It takes four to eight weeks. During that time, bills may go unpaid and the account may be frozen.
This is why people should create a durable power of attorney before they become incapacitated. If someone is already incapacitated and there is no durable power of attorney in place, the only legal way to access their accounts is through the court.
What happens to the power of attorney after death
The power of attorney dies with the account holder. The moment they pass away, your authority ends. You cannot withdraw money, pay bills, or access the account in any way, even if you have a key to the safe deposit box or the bank has already given you access.
If the account holder left a will, the will names an executor (sometimes called a personal representative). The executor's job is to settle the estate, which includes collecting money from bank accounts and distributing it according to the will. The executor has to go through probate court, which takes several months to over a year depending on the state and the size of the estate. During probate, the bank will freeze the account until the court issues an order releasing the funds.
If there is no will, the account goes through intestate succession, which means state law decides who gets the money — usually the spouse, then children, then parents, in that order. Again, the bank will not release money without a court order.
The fastest way to avoid this is if the account holder set up a payable-on-death (POD) designation or a transfer-on-death (TOD) designation when they opened the account. These let you name a person who automatically inherits the account when you die, without going through probate. If the account has a POD designation, the named person can claim the money by showing the bank a death certificate and their ID — no court order needed. Ask the bank whether the account has a POD or TOD designation. If it does not and you are the account holder, you can usually add one by filling out a form.
When a bank refuses to honor the power of attorney
Banks can refuse a power of attorney for several reasons, and they do not have to explain in detail. The most common reasons are: the document is too old (some banks have a 10-year rule, though this is not universal), the document is not notarized or certified, the bank thinks the document is forged, the account holder is deceased, or the account is a type the bank does not allow power of attorney access to (like a trust account or a retirement account).
If a bank refuses, ask them in writing what the specific reason is. If they say the document is invalid under state law, you can take it to an attorney to review — sometimes banks are wrong, and an attorney can write a letter explaining why the document is valid. If they say it is their policy not to honor powers of attorney for that account type, you are stuck with that bank, but you can move the money to a different bank that will honor it (if the account holder is still alive and able to authorize the move).
If the account holder is incapacitated and the bank refuses a valid durable power of attorney, you may have grounds to sue the bank or file a complaint with your state's banking regulator. But this takes time and money. It is easier to prevent this by choosing a bank that is known to be cooperative with powers of attorney, or by getting a court order through conservatorship if the bank will not budge.
Frequently Asked Questions
Can I use a power of attorney to access someone else's account without their knowledge?
No. A power of attorney is only valid if the account holder signed it while mentally capable and understood what they were signing. If you forged the document or the account holder did not authorize it, that is fraud. The account holder can revoke the power of attorney at any time if they are still alive and mentally capable. If they find out you accessed their account without permission, they can report you to police and sue you.
What if the power of attorney says I can access the account but the bank still says no?
Banks have the legal right to refuse a power of attorney even if it is valid under state law. Ask the bank in writing why they are refusing. If they cite a policy (like "we do not honor powers of attorney for joint accounts"), you cannot force them to change it. If they say the document is invalid, you can have an attorney review it. If the account holder is alive, you can ask them to move the account to a different bank or to sign a new power of attorney on the bank's own form.
Does a power of attorney let me add myself as a signer on the account?
Usually not. A power of attorney lets you act on behalf of the account holder, but it does not make you a legal owner or signer. Some banks will add you as a signer if you ask, but this is different from a power of attorney and requires the account holder's signature on a new account card. Ask the bank what they allow.
Can I use a power of attorney to access a joint account?
It depends on the bank and how the account is set up. Some banks treat a joint account as owned equally by both people, so a power of attorney over one person does not give you access to the other person's share. Other banks will honor the power of attorney. Call the bank and ask specifically about joint accounts before assuming you have access.
What should I do if I think someone is misusing a power of attorney to steal from an account?
Contact the bank when ready and tell them you suspect fraud. Ask them to freeze the account or flag it for review. If the account holder is still alive, they can revoke the power of attorney. If they are incapacitated, you may need to contact an attorney or file a report with adult protective services. If money has already been taken, you can report it to police and potentially sue the person who took it.
