I'm not sure exactly what the law requires but, I had the same situation with my dad and now that I think back I wish I had told someone that could help me .. I might be a different, more functional person today if I had, maybe saved myself a lot of heart ache too .. something to think about.

I obviously never did though even though I wanted to but I know how scary that situation is and I know that would be a lot of unknowns in your future so I Deffinatly get why you wouldn't, but take it from me I have some serious regrets that I could have stopped it sooner. Again good luck
