Illinois Arbitration Summons is a court document that is issued by a court of law in the state of Illinois. It is used to notify a party that they are required to appear and participate in an arbitration hearing. The arbitration hearing is a process of resolving a dispute between two or more parties by the use of a neutral third party. The arbitration hearing is usually used when the parties cannot agree on a resolution to the dispute on their own. There are three types of Illinois Arbitration Summons: 1. Preliminary Summons: issued at the beginning of the arbitration process to notify the parties that an arbitration hearing has been scheduled. 2. Rule Summons: issued when a party fails to comply with the rules of the arbitration process. 3. Final Summons: issued at the conclusion of the arbitration process to notify the parties of the results of the arbitration hearing.
