Sign the check in the account holder's name, then add your title

When you sign a check as power of attorney, you write the account holder's name first, then sign your own name below it with "POA" or "Power of Attorney" next to your signature. The bank needs to see both names so they know the account holder authorized the transaction and you are acting on their behalf, not spending their money as your own.

The exact format varies slightly by bank, but the standard method is: write the account holder's name on the signature line, then on the next line write your name followed by "as POA" or "as Power of Attorney for [account holder's name]". Some banks accept "Attorney-in-Fact" instead of POA. The key is making clear that you are signing in a representative capacity, not as the account owner.

Key Takeaways

  • Always write the account holder's name first on the check's signature line, then add your own name with your POA title below it.
  • Your bank may have a specific format they require, so call ahead or check your account documents to confirm their preferred signature style.
  • The account holder's name must appear on the check itself—never sign only your own name when acting as POA.
  • Some banks require you to register your POA document with them before they will honor checks signed this way.
  • Keep a copy of your POA document with your records in case the bank questions the signature later.

Register your POA with the bank before signing checks

Most banks will not honor a check signed as POA unless you have already filed your power of attorney document with them. Contact the bank's legal or compliance department and ask what they need to register your POA. They typically want an original or certified copy of the document, sometimes notarized, plus a form the bank provides.

This step is essential and often overlooked. A check signed correctly but without a registered POA on file will be rejected at the teller window or during processing, which can delay payment and create problems with whoever you are paying. Ask the bank how long registration takes—it usually ranges from a few days to two weeks—and do this before you need to sign checks.

What to write on the check itself

The payee line, amount, and date work exactly as they would if the account holder were signing. The only difference is the signature line. Write the account holder's name first, then your signature with your POA designation. Do not leave the account holder's name blank or write only your own name.

Example: If you are signing a check for John Smith, and you are his power of attorney, the signature line reads:

John Smith Sarah Johnson, POA

Some banks print a second signature line on business checks for this purpose. If your checks have two lines, use the first for the account holder's name and the second for your signature and title. If there is only one line, write both names on it, with the account holder's name first.

Common mistakes that cause checks to bounce

The most frequent error is signing only your own name without the account holder's name. Banks will reject this because it looks like you are drawing on the account as the owner, not as a representative. The second mistake is forgetting to register the POA with the bank beforehand—the signature will be correct, but the bank has no record that you are authorized to sign.

Another common problem is using an outdated or revoked POA document. If the account holder created a new POA that supersedes the old one, or if the original POA has an expiration date that has passed, the bank will not honor checks signed under it. Confirm with the account holder that the POA you registered is still current and has not been revoked.

Some people also make the mistake of not keeping the POA document accessible. If the bank questions the signature, you need to produce a copy quickly. Store a copy with your important papers and keep another with your banking records.

What happens if the bank refuses the check

If a check is rejected, the bank will usually send it back to you with a reason code. Common reasons are "signature does not match," "POA not on file," or "improper signature." Contact the bank when ready to find out which issue caused the rejection.

If the problem is registration, you can often resolve it in one visit by bringing your POA document to a branch and completing their registration form. If the signature format is wrong, ask the bank to show you their preferred format in writing, then rewrite the check and resubmit it. If the POA has expired or been revoked, you will need a new POA document from the account holder before you can sign any more checks.

Differences between personal and business accounts

Personal checking accounts usually have one signature line, so you write both names on the same line with your POA designation. Business accounts often have two signature lines—one for the account holder and one for the authorized signer. If your account has two lines, use them as intended: account holder's name on the first line, your name and POA title on the second.

Some business accounts require additional documentation, such as a corporate resolution or board approval of the POA. Ask your bank whether your account type has any special requirements beyond the standard POA registration.

Keeping records of checks you sign as POA

Maintain a record of every check you sign as power of attorney. Write down the check number, date, payee, amount, and what the check was for. This protects both you and the account holder by creating a clear audit trail of how the account was used.

Keep these records separate from your personal finances. If the account holder or their family ever questions how money was spent, or if there is a legal dispute, these records show that you acted responsibly and transparently. They also help you reconcile the account and catch errors or fraud.

Frequently Asked Questions

Can I sign a check as POA if the account holder is still alive and able to sign?

Yes. A power of attorney remains valid even if the account holder is alive and capable. You can sign checks on their behalf whenever they authorize you to do so, whether they are unable to sign themselves or straightforward prefer to have you handle their finances. The account holder can revoke the POA at any time if they change their mind.

What if the bank says they have never heard of POA signatures?

Some smaller banks or credit unions may not be familiar with the process. Ask to speak with the compliance or legal department, not just a teller. Bring a copy of your POA document and ask what format they need. If they continue to refuse, you may need to move the account to a bank that accepts POA signatures, or ask the account holder to add you as an authorized signer instead.

Do I need the account holder's permission every time I sign a check?

That depends on the terms of your POA document. A general POA usually grants you broad authority to sign checks without asking permission each time. A limited POA may restrict you to specific checks or amounts. Review your POA document to understand what authority it gives you, and follow those limits.

What if the account holder dies—can I still use checks I signed as POA?

No. A power of attorney ends when the account holder dies. Any checks signed after death will be rejected. At that point, the account becomes part of the estate and must be handled by the executor or administrator named in the will. Do not sign any more checks once the account holder has passed away.

Can I deposit a check made out to the account holder if I sign it as POA on the back?

Yes, but the endorsement format matters. On the back of the check, write "For deposit only" followed by the account number, then sign the account holder's name with "POA" or "Power of Attorney" next to it. Some banks require you to write "as POA for [account holder's name]" to be completely clear. Call your bank to confirm their preferred endorsement format before you deposit.
