Can a power of attorney (POA) be changed or revoked?
Lets say your friend has named you her agent through a power of attorney, which means shes given you the authority over her finances. She can take away your authority to act as her agent at any time if she wants to and is still able to make decisions. If she does take away your authority as her agent, you must stop making decisions for her. She should tell any businesses or people you were dealing with about her decision to take away your authority.
If you think your friend does not understand the decision she made to remove your authority and is being abused or exploited by someone else, talk to a trusted family member, a lawyer, an official from adult protective services, the police, or the sheriff.
