Illinois Summons — 30 Day is a legal document issued by a court in the state of Illinois that orders a person to appear in court within 30 days. It is typically issued when someone has been accused of a crime or is a defendant in a civil lawsuit, and serves as a formal notice of the court date. There are two types of Illinois Summons — 30 Day: a summons in a criminal case and a summons in a civil case. In a criminal case, the summons will inform the defendant of the charges against them and include details of the court date, time, and location. In a civil case, the summons will inform the defendant of the complaint against them and include details of the court date, time, and location. Both types of summons are legally binding and require the recipient to appear in court on the specified date.
