I can totally understand what you are going through. My dad remarried after my mother died. I tried to talk to my father before the wedding to tell him I would like some of my mother's jewelry just for sentimental reasons. He got furious with me. Well, she took all my mother's good jewelry (engagement ring and diamond wedding band) and tossed the tidbits my way. Her name got put on the deed to the house. She decided to divorce him and said she would let him buy her out for $20,000 cash. He got off cheap! Later she told him she should have held out for more. After that, he lived with a woman for years. She told me they were keeping everything separate for each family. Come to find out, she was keeping her money separate while my father was leaving everything to her. He even put her name on the deed to the house. Now, they were not married. My mother was responsible for alot of what my dad had -money for the house, stocks, etc. I found this all out because she ended up passing away and 2 years later my father decided he needed to change his will back to leaving everything to my brother and I. I am not a money hound but I did not want to see her and her family get everything my parents worked for, especially my mother. And I do realize he could leave it to whoever he wanted to but I did not think it was right to leave out his kids and grandkids. There are alot of sentimental items in his house that I would like to have to remember my mother. His ex-wife already stole her good jewelry. I have a friend who went through something similar and she and her father are just getting back on speaking terms. (Her family did not like the new wife at all!) It is a difficult situation but maybe your dad could talk with a financial advisor for seniors to be sure everything is in order now. Good luck!
