The Illinois General 30-Day Summons is a legal document used to initiate a lawsuit in the state of Illinois. It is issued by the plaintiff, who is the party initiating the lawsuit, and is typically served upon the defendant, who is the party being sued. The summons contains the names of the parties involved, the court in which the lawsuit will be filed, the cause of the action, and the date of the summons. It also includes a notification that the defendant must appear before the court to answer the complaint within 30 days from the date of service. There are two types of Illinois General 30-Day Summons: Original Summons and Supplemental Summons. The Original Summons is the initial summons issued in a lawsuit, while the Supplemental Summons is issued when additional parties are added to the lawsuit.
