Also found in: Dictionary, Thesaurus, Medical, Legal, Encyclopedia, Wikipedia.
An impartial third party asked to resolve a disagreement without forcing the disputants to go to court. The parties to the dispute agree to make their cases before one or more arbiters and to abide by whatever decision the arbiter or arbiters make, each party forgoing the right to an appeal. There are generally three arbiters, but there may be up to five. An arbiter is also called an arbitrator, or, less formally, an umpire.
