living home still. Aging mother in mid-advanced althezeimers living at near by care facility. Dad is causiing serious issues-insits he is going to take her home in next 30 days. He is verbally abusive to her and harrasing me( i have power of attorney) and her facility with all sorts of matters related to her care. Refuses to pay her bill and is verbally abusive and manulating me as he feels I am not taking his side. What action do i need to take as he is not fit to take care of her. Do i need to get Dr. or attorney involved?
