When my sister drinks, her early dementia symptoms get worse. She has had multiple mild strokes that have affected her short term memory. My niece and I have POA and MPOA and my sister has her own will/trust but brother-in-law doesn't know yet-all hell will break loose when he finds out. He is pressuring my sister to give him access to money that is solely hers. Most of the family believe he is trying to hasten her demise as his personal mantra is "whoever dies last wins".
There is no money to speak of so putting my sister into an assisted living facility isn't an option. We don't know what to do to protect her. APS was called but nothing came of it. Help!
Your Sister and her husband live together, I assume, a married couple?
And you have contacted APS who found no problems they could address?
I think that you have basically done what you are able. You cannot place your sister against her will unless her dementia is severe, and you have guardianship. If her husband fights to have guardianship and keep her home, it is unlikely you would win.
I would say you are now in the realm of what your sister herself wants. Has she expressed a wish to leave her husband? If so there are ways to do that no matter she has money or not. If she wishes to stay with him I am afraid intervention at present is at a standstill. If you have POA you may wish to discuss the alcohol problem with your Sister's doctor, but I don't know that he could directly intevene in any way. Unless you live with them it is difficult to say whether your sister is drinking because she herself chooses to, or because she is being "encouraged" to do so.
