They are not legally married. I had told all the children and lawyers and doctors that he was like this, all the proper reporting to agencies was followed. I placed Mom in the assisted living alone so she could be away from his home, and safe, his kids wanted him there with her, so my siblings agreed. They never did and still don't visit, or help me and ignore his decline and behavior. Now, assisted living wants him out, I want Mom to stay in this facility alone, she does too, she is 96 and blind and deaf, (almost completely) and weak. Brother tricked her into giving him POA. Siblings don't even want these two in assisted living, they want the money for themselves. I'm afraid for my mother, whom I take to all her doctors and outings because I am ten minutes away. Help! Her affairs are separate from her partner, I don't want siblings to move mom if her partner has to go!
She can also very easily change the POA if she wants to. The POA does not give Brother the right to move her anyway, but removing it from him might cool his jets a bit!
If one of the agencies you contacted was APS, call them again to report what’s happening. You fear for your mother’s physical safety. Is she self-pay? If so, the sibs won’t be recognizing any financial windfalls. You can also contact an Elder Law Attorney. Just because you don’t have POA doesn’t mean you don’t have any rights at all. Is the AL staff aware of her partner’s abuse? Is there a social worker involved? If he yells at her they must hear him and investigate. They are, on some level responsible for her safety too.
Good luck. Please let us know how things are going.
