Arbitration is a method of resolving disputes outside of court, where a neutral third party, called an arbitrator, listens to both sides and makes a decision. Arbitration is an Alternative Dispute Resolution (ADR) process used to resolve disputes outside the court system.Most car insurance policies let you resolve your dispute through an outofcourt process called arbitration. Less formal than a courtroom jury trial. Insurance arbitration relies upon an arbitrator (the neutral third party) to make an appropriate decision based on the specifics of a claim or case. The AZ-RUAA applies to all arbitration agreements made after January. Under § 123003, the RUAA now applies to every agreement to arbitrate, even if the old UAA was in force when that agreement was entered into. Under AAA rules, parties to AAA cases agree that the arbitration award can be entered as a judgment in any federal or state court with jurisdiction.
