How Does Power of Attorney Affect Bank Account Access?

Updated July 9, 2026 6 min read

Someone doesn’t have to be listed as an owner on an account to be able to manage it — a power of attorney document can grant that access instead.

The short answer

A power of attorney is a legal document that lets one person, called the agent or attorney-in-fact, act on behalf of another person, called the principal, including managing their bank accounts. The scope of that authority depends on how the document is written, and a bank will typically require its own review of the document before granting access.

General versus limited power of attorney for banking

A general power of attorney tends to grant broad authority over the principal’s financial affairs, which usually includes the ability to deposit, withdraw, and otherwise manage bank accounts alongside other financial matters. A limited, or special, power of attorney restricts the agent’s authority to specific tasks or accounts spelled out in the document — for example, managing one particular account for a defined period, rather than all of the principal’s finances. Understanding which type is in place matters because it determines exactly what an agent can and cannot do at the bank.

How a bank verifies the document

Banks generally don’t just take a power of attorney document at face value. Many require the agent to bring the original or a certified copy to a branch, complete the bank’s own internal forms, and sometimes have the document reviewed by the bank’s legal or compliance department before authority is added to the account. Some banks also require the document to have been drafted or notarized in a way that meets their specific standards, which can vary by institution, so it’s common for this process to take longer than people expect. This is a different mechanism than an authorized user on a credit card or a joint account holder, since a power of attorney doesn’t necessarily make the agent a co-owner of the funds.

What an agent can typically do once authorized

When this authority ends

A power of attorney typically ends when the principal revokes it, when the document specifies an end date, or upon the principal’s death, at which point the account would instead be handled through the estate process, similar to how an estate account after someone dies takes over financial administration. Some powers of attorney are also written to become effective only if the principal becomes incapacitated, which is a distinction worth understanding when the document is drafted.

What to weigh

Granting power of attorney over a bank account is a significant decision because the agent’s authority, once granted and accepted by the bank, can be quite broad depending on the document’s terms. Because the specifics depend on state law and how the document is drafted, and because rules can change over time, anyone setting this up should treat it as a matter for careful review rather than a simple form to fill out.
