First, there is the judge. In many courts, the judge will be wearing a black robe. The judge usually sits at the front of the courtroom on the bench. The judge’s name is often on a sign near the bench.
The judge does many things. First, the judge is like a referee at a ball game. The judge makes sure that everyone plays by the rules.
Sometimes the judge is also the person who decides the argument that people came to court about. For example, if two people come to court because they disagree about money, the judge might be the person who finally decides who gets the money.
