Law Training on Family Arbitration is provided here. Arbitration is a dispute resolution process in which the parties hire a neutral third party, a family law arbitrator, to make a decision resolving their dispute that they agree they will be bound by. While the job of a mediator is to help two people work towards a solution that they make for themselves, the arbitrator's job is to act like a judge and impose a resolution, after hearing the evidence and listening to the arguments of each party.
