My biological father recently passed, he and his family never formally acknowledged me as his daughter, although he has admitted it to me over the years. His wife was very active in church and community and considered me an embarrassment. He is extremely weathly, owned much of the town they lived in. I assume he willed his estate to his wife and 4 sons, can I sue for inheritance? Paternity has never been proven, but I know my DNA would match his sons.
