I live in California and I need to know, can I sue to get some money from my deceased fathers estate? My father was married for 48 years and they had 2 children between them, however, he cheated on his wife with my mother and I was born. He has always been in my life. However, I don't think that my half siblings know about me. I really don't know. Our father recently died unexpectedly on March 5, 2011. My father used to always say that I would be taken care of if anything happened to him. I don't know who to contact but I am interested in finding out my rights, or if I have any.
