When someone gives you Power of Attorney (POA), you can legally sign legal documents on their behalf if necessary. However, signing this document isn’t as simple as writing down both of your names. For a power of attorney signature to be valid, you must take the proper steps.
Read on to learn how to correctly sign as power of attorney, so you don’t encounter any issues if you need to sign documents on someone’s behalf.
What Is a Power of Attorney?
A power of attorney is a document that creates a legally binding agreement between two parties — a principal and an attorney-in-fact.
A power of attorney form grants an attorney-in-fact the right to:
- access the Principal’s financial accounts
- sign legal documents on the Principal’s behalf
- manage the Principal’s legal and business affairs
As an attorney-in-fact, you must act in the Principal’s best interest and adhere to their wishes when signing documents. This means doing what the Principal wants you to, no matter what.
A durable power of attorney form remains effective if you become incapacitated and unable to communicate your wishes.

6 Steps for Signing as Power of Attorney
Acting as someone’s attorney-in-fact can feel a bit complicated. Follow these steps to ensure the process runs smoothly and meets legal requirements:
Step 1: Bring Your Power of Attorney Agreement and ID
When signing as a POA, you need to bring the original form to the meeting — even if you’ve already registered a copy of the document with the institution (such as a bank, financial agency, or government institution).
You also need to bring government-issued photo identification with you. This allows the institution to confirm that you’re the person named in the document and lets them verify the signature on a Power of Attorney is yours.
Step 2: Determine the Preferred Signature Format
Most agencies or institutions require a specific format when signing under Power of Attorney. Consider calling ahead to establish what format is preferred — if any.
If there’s no preference, use a standard format such as the one in the signature sample below:
[Principal’s name]
by [Your name]
Power of attorney
Step 3: Sign as the Principal
The proper way to sign a Power of Attorney is to first write the Principal’s signature. This shows that you’re acting on the Principal’s behalf, not your own.
And remember to use the Principal’s full legal name. If you see their name listed on any pre-existing paperwork at the institution, replicate its format.
Step 4: Sign Your Name
Sign your name below the Principal’s name. Add the word “by” in front of your name to indicate you’re signing as POA on the Principal’s behalf.
Step 5: Express Your Authority as Attorney-in-Fact
Below your name is where you make it clear that you have the authority to sign on the Principal’s behalf. To indicate that you’ve been given signing authority, write “attorney-in-fact” under your name. Other variations, like POA or “power of attorney, ” are also acceptable to write out.”
Failing to indicate that you’re signing on the Principal’s behalf can invalidate the agreement and even lead to civil or criminal lawsuits.
Here’s a sample of what a power of attorney signature should look like:
Step 6: File the Documentation Somewhere Safe
The final step is to file each document you’ve signed in a secure location.
It can be challenging to know you have to sign a Power of Attorney for a loved one, but it can be a simple task if you prepare accordingly.
Be sure to follow any directions while maintaining a clear record of the proceedings for future use.
You should note that the law prohibits using a Power of Attorney after the Principal’s death.
