My dads father recently passed away. His father and mother had been separated for three years at the time of his death. As he had no assets besides his car, he never made a will. Before he passed away however, he was given a generous sum from a friend who left it as a Thankyou for all the help he had given him throughout the years. He spent half of it before his death. My fathers mother has decided (after originally saying she wanted none of the money) that she wants all of it. Does she have this claim? Or does it fall to the children? And does my father have some claim of control and distribution of what little his father had, seeing as he is the oldest child?
