Our father's wife (remarried 10 years ago, she's 74 yo) has had her lawyer threaten us with a "court action" in a letter. About 6 months ago, we brought our father to live with us, instead of at his home with his wife. We had discovered that his Alzheimer's and the wife's condition had led to a house with rats, my father losing about 20lbs on his 84 yo body, and being hospitalized with his hemoglobin at 5. After two months in their home, trying to improve things, talking with her, I felt some time at our place would be safer, healthier, etc. He's been with us since, and he hasn't expressed any desire to return to his old home. He just says things are taken care of for him here, he has time to do his hobbies. I have a Power of Attorney that he signed, plus a Will, but they were done post diagnosis by a neurologist of his Alzheimers. So where do we stand?
