Arbitration is a process where a dispute is submitted to an impartial third party, whose decision is usually binding. It involves both parties presenting their case to an arbitrator they choose or who is appointed by statute. The arbitrator reviews evidence and issues a decision based on equity and justice. Arbitration is best for resolving contractual disputes, while mediation is better for disputes over interests. Arbitration has advantages like bringing the process closer to the parties and being more flexible, expeditious and cost effective than litigation. There are two main types - voluntary arbitration agreed to by both parties, and compulsory arbitration required without consent.
