My mother is widowed as of four years ago. Although she has plenty of money, she had millions stolen from my nephew (cash left in the attic). Still she has real estate, rentals that I manage, and we have sold some, so she still has a large estate. She allows me to be joint on her accounts, but no POA. She insists she can do whatever she wants with her money and no one can tell her what to do. She still drives, plays bridge, etc. But, I see where she is becoming very forgetful. Constantly changing her mind about what she is going to do with her money. My brother recently came into town from out of state, lied to her about some stuff, and she wrote him a check for $20,000 to keep the peace (I was upset, because my brother wouldn't even allow me to call and talk to her, without listening in on the phone.). He came to town with an agenda, to manipulate her by arriving with a big trailer to get something worth 8K. He told her it was worth 20K. Therefore, she sent him away with the check instead. I am so angry and upset, I want nothing more to do with him. I am wondering when he will come back. I am the only local sibling. Never got along well with my mother. But after nephew stole all the money from her, I got put into the position of managing all her money and real estate. I am sick about all of this. I feel helpless. My brother is gleeful, because he thinks "he won". I am so disgusted by all this. I frankly feel like if I can't put POA or other safeguards in place, I am ready to walk away. Let the chips fall where they may. My mother is cocky and will do what she wants, and is 100% sure of her competency (which is failing). Any advice?
