Arbitration is an avenue for resolution of legal disputes outside of the court system. The parties to a dispute refer the matter to one or more persons, i.e. the arbitrators. The decision of the arbitrator(s) is a final resolution of the dispute which may be enforced, if necessary, in a court. Parties to many types of contracts may agree in advance in the contract to submit controversies to arbitration. Even in the absence of such a valid agreement, after a controversy has arisen parties may agree to use arbitration to resolve the dispute. The arbitrators are normally paid by the parties to the arbitration. While arbitration takes place outside the court system, it is still necessary to assemble and effectively submit to the arbitration board evidence supporting a party’s position.
