Legal Definition
An arbitrator is an individual or panel tasked with resolving a dispute between two or more parties through the process of arbitration, which is a formal, agreed-upon method of settling legal disagreements outside of the court system.
Plain-English Translation
Imagine an arbitrator as a judge who makes decisions when people disagree over something. They are hired to listen to both sides and decide on the right answer for a legal problem instead of just letting the judge decide alone.
