I am my father’s General Power of Attorney/Agent (Attorney in Fact) and have the power and authority to perform or undertake any actions he could perform or undertake as if he were personally present. My question is: This Power of Attorney document appoints one of my sisters as my successor, and I would like to know if I have the authority to have that document changed to appoint our other sister as my successor. My father is 92 and has been having quite a bit of short term memory loss over the past year. My current successor is in financial difficulty, as well as her offspring, and I feel I am responsible to protect my fathers assets to the best of my ability and would like to see that carried out to his wishes should something happen to me. Thank you!
