Find a format to follow so you can write a notice revoking your POA. These are not legal documents you must file with the court, so you have some leeway as to how to construct one. Libraries, legal aid services and legal websites often provide blank forms you can either copy or fill out.
Complete the revocation form. Make sure you identify yourself and specifically state that you are revoking your power of attorney and the powers you granted to the person you named in it. Include the date of your POA.
Take the completed form and two witnesses to a notary public. You can usually find one working at a bank or law office. Make sure you and your witnesses have photo IDs with you. Sign the form in the presence of the notary.
Write the word “revoked” in large, dark letters on your power of attorney. Make copies of your POA, as well as your notice to revoke it. Attach a copy of your revoked POA to each copy of your revocation form.
Mail a copy of your revocation notice with its attached revoked POA to the person whose power you’re revoking. Send copies to all institutions, banks and health care providers you authorized him to deal with. Do this by certified mail, return receipt requested, so you have proof that each person or entity received it.
