Illinois Jury Demand is a legal summons issued to a prospective jury member in the state of Illinois. It is used to notify individuals of their obligation to appear in court to serve as a juror in a civil or criminal trial. There are two types of Illinois Jury Demand: Regular Jury Demand and Special Jury Demand. Regular Jury Demand is issued by the clerk of the Circuit Court in the county where the trial is to be held, and is sent by mail to residents of that county. Special Jury Demand is issued by the presiding judge in the case, and may be sent to residents of other counties. Both types of summons require that the prospective juror appear in court on the specified day and time.
