Do the people on judge judy pay their own fines?

Yes, the participants on "Judge Judy" are responsible for paying any fines or judgments awarded by the court. However, the show does cover the costs associated with the judgments, so the litigants do not have to pay out of pocket. This arrangement is part of the show's production budget. Ultimately, the decision rests with the judge, Judy Sheindlin, who determines the outcome of each case.
