An Illinois Pre-Trial Order (marital cases) is an order issued by the court prior to a trial in a marital case. It sets forth the rules and procedures to be followed at the trial, including the documents that must be filed and the deadlines that must be met by both parties. It also includes information about the parties' rights and responsibilities during the pre-trial process. There are two types of Illinois Pre-Trial Order (marital cases): a Joint Pre-Trial Order (JPO) and an Individual Pre-Trial Order (IPO). The JPO is used when both parties agree to the terms of the order and agree to proceed with the trial. The IPO is used when one party does not agree to the terms of the order and decides to proceed with the trial.
