A power of attorney (POA) is a legal document giving another individual the authority to act on your behalf. POAs are typically created for people who are either unable, such as in the case of illness, or unavailable, such as during a military deployment, to act on their own, so they grant others they trust to act for them. A POA can be misused if in the hands of an unscrupulous person. If this is the case, the POA can be revoked quickly by filling out a document to that effect and providing the institutions that have been or would honor the POA with a copy of the revocation.
Procure a copy of a Revocation of Power of Attorney form either from an attorney's office or online. To complete this form you will need the assistance of two witnesses and a notary public.
Fill out the form with your information and the information about the person holding the POA The form states that you wish to have the POA revoked. Sign the form in front of two witnesses and a notary public; have your witnesses sign the form and the notary public notarize it.
Inform all third parties that have been honoring the POA, such as banks or other financial institutions, that the POA has been revoked and provide them with a copy of the form.
Inform the person previously holding the POA that you have revoked it. It is advisable to tell this person after you have informed the banks to prevent any last minute abuse of the POA.
