In an adversarial system, many parties in a lawsuit hire lawyers to argue their cases for them.
Generally, in court cases in an adversarial system, opposing parties are trying to prove the opposite point. Witnesses, evidence and other support for arguments are often used by parties in an adversarial system in order to try to prove their argument. At the end of a court case, a judge or a jury will make a ruling on the case.
