Illinois Mandatory Arbitration is a form of alternative dispute resolution (ADR) that is required by law in certain cases in the state of Illinois. It is a process in which the parties to a dispute agree to submit their issues to a neutral third-party arbitrator who is chosen by the parties or appointed by a court. The arbitrator then hears both sides of the dispute and makes a binding decision, which is legally enforceable. There are two primary types of Illinois Mandatory Arbitration: binding and non-binding. Binding arbitration is a more formal process that binds the parties to the decision of the arbitrator. Non-binding arbitration is a less formal process that allows the parties to reject the arbitrator's decision and pursue litigation if they wish.
