If a person is on memory medication are they considered capable of revoking a POA and signing a new one?A friend's Dad is on memory medication and going through extreme cancer treatments. He has not been deemed incapable of making decisions, however I don't feel this is right considering his frame of mind. He is confused and easily swayed by family members, who until recently haven't been involved in his life. They swooped in and have had him revoke his existing POA, replacing it with a new one, naming themselves as the attorney. Funds have been withdrawn from his account and decisions made without the entire family present. Why are people so nasty? I have suggested legal assistance for the former attorney, as that would be the best choice. However just looking for some feedback to help an extremely frustrated and hurt friend.
