What a Power of Attorney Can and Cannot Do With a Joint Bank Account

A power of attorney can withdraw money from a joint account only if the account owner gave them that specific authority in writing

A power of attorney (POA) is a legal document that lets one person act on behalf of another. But the account owner — the person whose name is on the account — decides exactly what the POA holder can do. If the document says the POA can withdraw money, transfer funds, or write checks, then yes, they can do those things. If it does not say that, they cannot, even if they are also listed as a joint owner on the account.

The key word is specific. A POA that says "manage my financial accounts" might not include the power to withdraw cash. A POA that says "withdraw funds as needed" does. The bank will ask to see the POA document before allowing any transaction. If the document does not clearly grant that power, the bank will refuse, and the POA holder has no legal right to take the money.

This matters because a joint account owner and a POA holder are not the same thing. A joint owner has rights to the account by virtue of their name being on it. A POA holder has only the rights the document gives them — and those rights exist whether or not their name is on the account at all.

Key Takeaways

A POA can only withdraw money if the power of attorney document explicitly grants that authority; being a joint account owner does not automatically give a POA holder withdrawal rights.
The account owner writes the POA document and decides which powers to include — withdrawal, transfer, check-writing, or none of those.
Banks require sight of the actual POA document before processing any transaction a POA holder requests.
A POA can be revoked at any time by the account owner, which when ready ends the POA holder's authority to access the account.
If a POA holder withdraws money without authority to do so, they can be sued for theft or breach of fiduciary duty.

What the power of attorney document actually says

The account owner creates the POA document themselves or with a lawyer. They choose what powers to grant. Common financial powers include: withdraw cash, deposit checks, transfer between accounts, pay bills, close the account, or access account statements. The document lists each power separately, or groups them under broader language like "all financial transactions."

The problem is that "broader language" is vague. A court or a bank may interpret "manage my accounts" narrowly — meaning read statements and pay bills, but not withdraw large sums. To avoid confusion, the account owner should list the specific powers they want the POA to have. If they want the POA to withdraw money, the document should say "withdraw funds in any amount" or "withdraw cash as needed."

Some account owners create a POA that grants no financial powers at all — only the power to make medical decisions, for example. In that case, the POA holder cannot touch the bank account, even if they are a joint owner.

How banks verify the POA holder's authority

When a POA holder tries to withdraw money, the bank will ask for the original power of attorney document or a certified copy. The bank's compliance team will read it to confirm that withdrawal authority is actually listed. They will also check the date the document was signed and whether it has been revoked.

Some banks require the POA to be notarized. Others accept an unnotarized document if it is signed and dated. A few banks have their own POA form they prefer you to use, though they must also accept a valid POA from another source.

If the document does not clearly grant withdrawal authority, the bank will refuse the transaction. The POA holder cannot argue that they are a joint owner or that the account owner told them verbally they could withdraw money. The document is the only proof that matters.

Joint ownership does not override the POA limits

If someone is both a joint account owner and a POA holder, they have two separate sets of rights. As a joint owner, they can withdraw money because their name is on the account. As a POA holder, they can only do what the document says they can do.

This distinction matters if the account owner wants to limit what the POA holder can do. For example, an account owner might add their adult child as a joint owner so the child can access the account in an emergency, but also create a POA that restricts the child from closing the account or transferring large sums. The POA restrictions explore even though the child is a joint owner.

Conversely, if someone is a POA holder but not a joint owner, they still have the authority to withdraw money — but only if the POA document says so. Their name does not have to be on the account.

What happens if a POA holder withdraws money without authority

If a POA holder takes money from the account without the power to do so, they have committed theft or breach of fiduciary duty. The account owner can sue them for the amount withdrawn, plus damages. The account owner can also report the theft to police.

A POA is a fiduciary relationship, meaning the POA holder is legally required to act in the account owner's best interest. Taking money without authority violates that duty. Even if the POA holder intended to use the money for the account owner's benefit, if the document did not grant that power, it is still a breach.

This is why it matters to read the POA document carefully before handing it to a bank or allowing someone to act on your behalf. If you are the account owner and you discover unauthorized withdrawals, contact your bank when ready and consider legal action.

Revoking a POA ends withdrawal authority when ready

An account owner can revoke a POA at any time, for any reason, and does not need to give the POA holder notice. The revocation is effective as soon as the account owner signs a written revocation document.

However, the bank may not know the POA has been revoked unless the account owner tells them. If a POA holder tries to withdraw money after revocation, the bank will process the transaction if they have not been notified. The account owner would then have to sue the POA holder to recover the money.

To protect yourself, send written notice of revocation to the bank and ask them to flag the account. Keep a copy of the revocation letter. If the POA holder tries to use the old document after that, the bank should refuse.

When a POA is useful for joint accounts

A POA can solve a real problem: what happens if the account owner becomes unable to manage the account themselves — due to illness, injury, or cognitive decline — but does not want to add someone as a joint owner?

Adding a joint owner gives that person permanent rights to the account, even after the account owner recovers. A POA is temporary by design. The account owner can revoke it whenever they want, or it expires on a date they set in the document. This makes a POA useful for situations where you want someone to have access for a limited time or under specific conditions.

For example, an account owner might create a POA that grants withdrawal authority only if they are hospitalized for more than 30 days. Or they might grant authority to pay bills but not to withdraw cash. These conditions are harder to enforce with a joint owner, because a joint owner has the same rights as the account owner.

Frequently Asked Questions

Can a POA holder withdraw money if the account owner is still alive and able to manage the account?

Yes, if the POA document grants withdrawal authority. A POA does not require the account owner to be incapacitated. The account owner can create a POA while they are fully capable and let the POA holder use it whenever they want. This is called a "durable" POA and is common when someone wants help managing finances but does not want to add a joint owner.

What if the POA document says "all financial powers" — does that include withdrawing money?

Probably, but banks interpret broad language differently. Some will read "all financial powers" to include withdrawal. Others will ask for a more specific list. To avoid delays or refusal, ask the bank what language they accept, or have the POA document rewritten to list withdrawal explicitly.

Can a POA holder withdraw money from a joint account without the other joint owner's permission?

Yes, if the POA document grants withdrawal authority. The other joint owner has no say in what the POA holder does, because the POA is a separate legal relationship between the account owner and the POA holder. However, the other joint owner can see the withdrawal on the account statement and can sue if they believe the money was taken wrongfully.

Does the bank have to accept a POA document from another state?

Most banks will accept a valid POA from any state, but some have restrictions. Call your bank and ask whether they accept out-of-state POAs, and whether they require notarization or their own form. Having the document notarized makes it more likely to be accepted.

What if the account owner created a POA but never told the POA holder about it?

The POA is still valid. The account owner does not have to notify the POA holder that they created it. However, the POA holder cannot use it unless they know it exists. If the account owner wants the POA holder to use it, they need to tell them and give them a copy of the document.
