He sued his adoptive parents, Willie and Sue Coleman, over misappropriation and the pilfering of his trust fund in 1989. At the peak of his career in the early 1980s, in addition to movie and TV appearances, he made $70,000 per episode of "Diff'rent Strokes", a total of around $18 million in earnings! Coleman's parents set up a trust fund for his money, yet they carefully structured the arrangement to name themselves as paid employees of Coleman's production company so they could live off Coleman's salary. When the court finally dissolved the trust fund in 1986 upon Coleman turning 18, his parents' share was worth $770,000, while Coleman himself had only $220,000. Coleman then successfully sued both his parents and managers for $3.8 million in losses and won a $1,280,000 settlement. Afterward, Coleman (feeling used and betrayed) never saw or spoke to his foster parents or former accountants and managers ever again.
