A power of attorney (POA) document is written authorization that enables a person (called the “principal”) to appoint a trusted relative or friend (called the “agent” or “attorney-in-fact”) to manage specific health care decisions or legal and financial responsibilities for them. When signing as power of attorney, it is very important to clearly state that you are acting on behalf of the principal and not contracting for any debt or transaction personally.

It is a good idea to ask the institution requesting a signature if they require it to appear in a certain way because some bank forms and legal documents must be signed using a specific format. Regardless of how the signature appears, never sign your name without indicating in writing that you are signing as attorney-in-fact. Use the following pointers for how to sign using power of attorney to avoid any issues.

  1. Have a copy of the power of attorney document on hand when you sign anything on behalf of the principal. The POA may already be on file with the institution you are working with, but the process is often quicker and easier if you can produce the document upon request.
  2. Print the principal’s name first on the signature line. This ensures that the principal is the one engaging in the contract or transaction.
  3. After the principal’s name, write “by” and then sign your own name.
    (Principal’s name, by agent’s signature)
  4. Under or after the signature line, indicate your status as POA by including any of the following identifiers: “as POA,” “as Agent,” “as Attorney-in-Fact” or “as Power of Attorney.”
