My father died about 2 years ago. He left no will but my parents had a family trust that my mother, who is still alive, took over. 6 months after the funeral, my brother, who is normally quite tight-fisted and crying poverty, completely remodeled his 3000 sq ft home (easily over $100K), bought a new $50K car, and went on a multi week European vacation. Right after the funeral, my mother wanted us to fly to the east coast for a family reunion but my brother said he couldn't afford the air fare so those plans never got started. It seems to me he suddenly came into a lot of money. Could there have been a way for my father to leave him money under the table, so to speak?
