I lived with a family friend for the last two years of his life. Took care of him from going to doctors to bathing. Before he died he had his estranged brother come be power of attorney over his medical decisions. He made a will leaving me his house. His brother told me he didn't write it in the will but he was going to do what my friend wanted. Well its 8 months later and he's trying to sell the house do I have any leg to stand on?
