What a Power of Attorney Can and Cannot Do With Joint Accounts

A power of attorney generally cannot close a joint bank account on their own, even if they hold broad financial powers. The reason is straightforward: a joint account belongs to both account holders equally, and the bank requires consent from all owners to close it. A power of attorney acts on behalf of the person who granted them that authority — called the principal — but they do not become an owner of the account themselves.

The specific rules depend on the account type, the bank's own policies, and what the power of attorney document actually says. Some banks will allow a power of attorney to withdraw all funds and leave the account dormant, which functions like a closure without formally closing it. Others require the principal or both account holders to sign closure paperwork in person. A few banks have different rules for accounts where the power of attorney is also a named owner.

If the principal is alive and able to communicate, the simplest path is for them to close the account themselves, with or without the power of attorney present. If the principal is incapacitated or unavailable, the power of attorney will need to contact the bank directly to learn what that specific institution requires.

Key Takeaways

  • A power of attorney cannot unilaterally close a joint account because both account holders must consent, and the power of attorney is not an owner.
  • Banks have different policies: some allow withdrawal of all funds, some require the principal's signature, and some require both account holders to sign.
  • If the principal is alive, they can close the account themselves or authorize the power of attorney to do so in writing to the bank.
  • If the principal is deceased, the account becomes part of the estate and must be handled through probate or by the executor, not by the power of attorney.
  • Contact the bank's customer service or visit a branch with the power of attorney document to learn that bank's specific closure requirements.

Why Banks Treat Joint Accounts Differently

A joint account is owned by all account holders together. Each person has equal legal rights to the money and equal authority to withdraw it. When you grant someone power of attorney, you are giving them the right to act on your behalf — but you are not transferring ownership to them. The bank sees the power of attorney as your agent, not as a co-owner.

Closing an account is treated as an ownership decision, not a transaction. Withdrawing money is a transaction; closing the account means the account ceases to exist and the relationship between the bank and the account holders ends. Because of that, most banks require the signature of at least one actual owner. Some require all owners to sign.

This rule protects both the bank and the other account holder. If a power of attorney could close a joint account unilaterally, the other owner could lose access to their own money without warning. The bank could also face disputes later if the other owner claimed they did not consent.

What the Power of Attorney Document Says Matters

The language in the power of attorney document itself can affect what a power of attorney is allowed to do. A limited power of attorney might restrict the agent to specific actions — for example, "pay bills from the checking account" but not "close accounts." A general power of attorney typically grants broad financial authority, including the power to manage bank accounts.

However, even a general power of attorney does not override the bank's ownership rules. A document that says "my agent may close any of my bank accounts" still does not give the agent the right to close a joint account without the other owner's consent. The power of attorney can only control what the principal themselves could authorize; it cannot change who owns the account.

Some people add specific language to a power of attorney that says something like "my agent may close joint accounts on my behalf." This can help, but the bank still has the final say. The bank will look at its own policies and the account agreement, not just the power of attorney document.

How Banks Handle Closure Requests From a Power of Attorney

When a power of attorney walks into a bank or calls to close a joint account, the bank will typically ask to see the power of attorney document. They will verify that it is valid, that it has not been revoked, and that it grants the authority being requested. Then they will explain their own policy.

Some banks will allow the power of attorney to close the account if the principal is present and consents. Others require the principal to initiate the closure themselves, with the power of attorney present as a witness or helper. Still others require both account holders to sign the closure form, which means the other owner must also be present or must sign separately.

If the principal is incapacitated and cannot sign, the bank may refuse to close the account without a court order. In that case, the power of attorney would need to contact an attorney to explore whether a guardianship or conservatorship is necessary, or whether the account can be handled through other means — such as leaving it open but inactive, or waiting until the principal's death and handling it through probate.

When the Principal Is Alive and Able to Consent

If the principal is alive and mentally capable of making decisions, the fastest way to close a joint account is for them to do it themselves. They can go to the bank alone, or they can bring the power of attorney with them. The bank will close the account based on the principal's request.

Alternatively, the principal can write a letter to the bank authorizing the power of attorney to close the account on their behalf. This letter should be specific — it should name the account, the account number, and state clearly that the principal authorizes the power of attorney to close it. The principal should sign it in front of a notary if the bank requests notarization. The power of attorney can then present this letter along with the power of attorney document.

If the other account holder is also alive and capable, they can also be asked to consent in writing. Some banks will accept written consent from both owners without requiring them to be present in person, though policies vary.

When the Principal Is Incapacitated or Deceased

If the principal is incapacitated — for example, in a coma or with advanced dementia — and cannot sign documents or communicate consent, the power of attorney's options are limited. The bank will likely refuse to close the account without a court order, because there is no way to verify that the principal would have wanted the account closed.

In this situation, the power of attorney can ask the bank whether the account can remain open but dormant, with no activity. This avoids closure but also avoids ongoing fees. Alternatively, if the principal has a living will or healthcare directive that names a healthcare proxy, that person can work with the power of attorney to explore whether a guardianship or conservatorship is necessary.

If the principal dies, the power of attorney's authority ends immediately. The account becomes part of the principal's estate and must be handled by the executor or administrator named in the will, or by the heirs if there is no will. The surviving account holder may also have rights to the account depending on how it was titled and the state's laws on joint accounts.

What to Do If the Bank Refuses to Close the Account

If a bank refuses to close a joint account even though the power of attorney has presented valid documentation, ask the bank to explain their specific policy in writing. Request the name and contact information of a manager or supervisor. Some banks have a customer advocate or ombudsman who can review the decision.

If the principal is present and capable, they can file a complaint with the bank's regulatory agency — usually the Office of the Comptroller of the Currency (OCC) for national banks, or the Federal Deposit Insurance Corporation (FDIC) for state banks. The complaint should explain that the bank is refusing to honor the principal's request to close the account.

If the principal is incapacitated and the bank is refusing to close the account without a court order, an attorney can help the power of attorney petition the court for a guardianship or conservatorship, which would give them the legal authority to make decisions about the account. This is a more formal process and takes longer, but it may be necessary if the account is causing problems — for example, if fees are accumulating or if the other account holder is misusing the account.

Frequently Asked Questions

Can a power of attorney withdraw all the money from a joint account?

Yes, in most cases. Withdrawing money is a transaction, not an ownership decision, so banks usually allow a power of attorney to withdraw funds on behalf of the principal. However, the power of attorney cannot withdraw money that belongs solely to the other account holder. If the account is truly joint with equal ownership, the power of attorney can withdraw the principal's share.

What if I am a power of attorney and also a named owner on the joint account?

If you are both a power of attorney and a co-owner, you have more authority, but the rules still depend on the bank. Some banks will allow you to close the account because you are an owner. Others will still require the other owner to consent. Contact your bank to ask about their specific policy for accounts where one owner also holds power of attorney for the other.

Can a power of attorney close a joint account after the principal dies?

No. A power of attorney's authority ends when the principal dies. After death, the account must be handled by the executor named in the will, or by the heirs if there is no will. The surviving account holder may also have rights to the account. Contact the bank and provide a death certificate to learn what steps are required.

Do I need a lawyer to close a joint account as a power of attorney?

Not usually. Most banks will close a joint account if the principal signs a request or if both owners consent. You only need a lawyer if the bank refuses and you need to pursue a court order, or if the principal is incapacitated and a guardianship or conservatorship is necessary.

What should I bring to the bank to close a joint account as a power of attorney?

Bring the original power of attorney document, a photo ID, and the account number. If the principal is present, bring their ID as well. Call the bank first to ask whether they need anything else — some banks require a notarized letter of authorization or a specific closure form filled out in advance.
