n. one who conducts an arbitration, and serves as a judge who conducts a "mini-trial," somewhat less formally than a court trial. In most cases the arbitrator is an attorney, either alone or as part of a panel. Most court jurisdictions now have lists of attorneys who serve as arbitrators. Other arbitrators come from arbitration services which provide lists from which the parties can agree on an arbitrator (many of whom are retired judges-even "People's Court" Judge Wapner is on such a panel in Los Angeles County). There is also the American Arbitration Association which usually has a panel of attorneys chosen by the association. Professional arbitration services are paid well to move cases along. There are also arbitrators who are experts on everything from construction to maritime damage. In some contracts there is a provision for such an expert-type arbitrator named by each side with a third chosen by the other two.
