Arbitration is a binding adjudicatory process to resolve legal disputes out of court. The parties must choose, in writing, to have their claims heard by an arbitrator or panel of arbitrators. The parties choose the set of rules that will apply to the arbitration. Court rules of evidence do not apply strictly. After allowing limited discovery and conducting a hearing, the arbitrator issues an award which the parties can enforce in court. Most arbitrations are final and binding; however the parties can opt for a non-binding, or advisory, award.
