Yes, a power of attorney can sign checks if you give them that authority

A power of attorney (POA) can sign checks on your behalf, but only if the document you sign specifically grants them that power. The authority to sign checks is not automatic—you must name it explicitly when you create the POA, just as you would name any other financial power. The person holding the POA (called the agent or attorney-in-fact) can then write checks from your account as if they were you, and the bank will honor those checks as long as the signature matches what you authorized.

The key is that your bank needs to know the POA exists and that it covers check-signing. You will need to show the bank a certified copy of the POA document and often complete a form the bank provides. Without that step, the bank will refuse checks signed by anyone but you, even if a valid POA exists.

Key Takeaways

  • Check-signing authority must be written into the power of attorney document itself—it does not come automatically with a POA.
  • You must notify your bank in writing and provide a certified copy of the POA before the agent can sign checks on your account.
  • The agent's signature on checks must match the signature sample you provide to the bank, or the bank may refuse the check.
  • You can revoke check-signing authority at any time by notifying the bank in writing, even if the POA itself remains in effect for other purposes.
  • A limited POA can restrict check-signing to certain amounts, certain payees, or certain time periods if you want to set boundaries.

What language in the POA document grants check-signing power

When you create a power of attorney, you choose which financial powers to grant. Check-signing is usually listed as a separate item alongside powers like "withdraw funds," "deposit checks," "pay bills," or "manage accounts." Some POA forms use broad language like "all financial powers" or "banking powers," which typically includes check-signing. Others list specific powers, and you check boxes next to the ones you want to grant.

If the document says the agent has power over "banking" or "financial accounts" but does not mention checks specifically, the agent may still be able to sign checks—but the bank might refuse without clearer language. To avoid confusion, use a POA form that explicitly names "authority to sign checks" or "authority to execute checks and drafts." If you are unsure whether your existing POA covers check-signing, contact the attorney who drafted it or ask your bank whether they will accept checks signed under your current document.

How to notify your bank and set up check-signing authority

Once you have a POA that grants check-signing power, contact your bank's customer service or visit a branch in person. Tell them you want to authorize someone to sign checks under a power of attorney. The bank will give you a form to complete—usually called a "Power of Attorney Notification" or "Authorized Signer Form." You will need to provide the agent's full legal name, address, and date of birth.

Bring a certified copy of the POA document itself. "Certified copy" means a copy that has been stamped or signed by a notary public or the court that issued it. A photocopy of the original is usually not enough. The bank will keep the certified copy on file and may ask the agent to sign a signature card so they can compare the signature on checks to the one on file. Some banks also require the agent to visit the branch in person to verify their identity before allowing check-signing.

The process typically takes a few business days to a week. Ask the bank for a written confirmation once the agent is authorized, so you both have proof that the bank has accepted the POA.

Limits you can place on check-signing authority

You do not have to give the agent unlimited check-signing power. When you create the POA, you can restrict the authority in several ways. You might limit the amount per check (for example, "no single check over $5,000"), limit the payees (for example, "checks to pay utilities and medical bills only"), or limit the time period (for example, "authority ends on December 31, 2026"). These restrictions go into the POA document itself.

You can also create a limited power of attorney that grants check-signing for a specific purpose—such as paying bills while you are out of the country for three months, or managing a specific account. A limited POA is useful if you want to give someone temporary authority without granting broad financial control. The bank will honor the restrictions written in the document, so the agent cannot sign a check that violates them without the check being invalid.

What happens if the agent signs a check without authority

If someone signs a check on your account without a valid POA, the check is a forgery. Your bank should refuse it, and if they cash it anyway, you can dispute the charge and the bank must refund the money. If the person who signed the check did so intentionally and without your permission, that is fraud, and you can report it to the police and your bank's fraud department.

If the agent has a POA but signs a check that violates the restrictions in the document—for example, a check for $10,000 when the limit is $5,000—the check may still be honored by the bank if the bank did not know about the restriction. However, you can hold the agent legally responsible for violating the terms of the POA. This is why it is important to give the bank a copy of the actual POA document, not just tell them verbally about the restrictions.

How to revoke check-signing authority

You can revoke the agent's check-signing authority at any time, even if the POA itself is still in effect for other purposes. To do this, contact your bank in writing and tell them to stop honoring checks signed by that person. Provide the agent's name and the date you want the revocation to take effect. The bank will update their records, and any checks the agent tries to sign after that date will be refused.

You should also notify the agent directly that their check-signing authority has ended, so they do not attempt to sign checks and face embarrassment or confusion at the bank. If you want to revoke the entire POA (not just check-signing), you will need to sign a formal revocation document and provide it to anyone who has a copy of the original POA, including your bank, your agent, and any other institutions that rely on it.

Frequently Asked Questions

Can the agent sign checks in their own name, or do they have to sign your name?

The agent must sign your name, not their own. The check should read "John Smith, by Jane Doe, Attorney-in-Fact" or "John Smith as Attorney-in-Fact for Jane Doe." The agent's signature goes below that. If the agent signs only their own name, the check is not valid under the POA and the bank may refuse it.

What if my bank refuses to accept the power of attorney?

Some banks have their own POA forms and will only accept checks signed under their specific document. Ask the bank whether they have a form you can use instead of your current POA. If the bank still refuses, you may need to switch banks or work with an attorney to challenge the bank's decision. Banks can set their own standards, but they must explore them consistently.

Can I give check-signing authority to more than one person?

Yes. You can name multiple agents in the same POA document, and each can have check-signing authority. You can also specify whether they must act together (both must sign every check) or separately (either one can sign alone). This is useful if you want backup authority or if you want to require approval from two people before large checks are written.

Does the agent have to tell me every time they sign a check?

No, there is no legal requirement for the agent to notify you. However, you should set up a system with the agent to track checks—for example, asking them to send you copies or to log transactions in a shared document. This protects both of you by creating a record and preventing misunderstandings about what money was spent and why.

What if the agent dies or becomes incapacitated?

The agent's authority to sign checks ends when ready upon their death or incapacity. Notify your bank right away so they stop honoring checks signed by that person. If you named a successor agent in the POA, that person can take over check-signing authority once you notify the bank and provide a new signature card.
