Dad got in trouble when he responded to a scammer on Amazon. Dad was going to give scammer money. The bank caught it and called me since I signed POA on his account at his request. I called sibling to help in the emergency. Now sibling has Dads checkbook and gives out checks upon request, one by one. Bank is now calling sibling not me. Sibling is not talking to me about it. I feel uncomfortable. I do not know where to get advice or who to trust. I think sibling is protecting but am uncomfortable with the degree of control. Dad has a medical POA but not a financial POA. I’m not sure what the POA was that I signed for the account. I think that account is closed now and new accounts were opened to escape the scammer.
