The Illinois 30-Day Summons is a document that is issued by a court or government agency to compel an individual or business to appear in court or comply with a legal order. The summons must be served in person by someone other than the petitioner, usually a sheriff or process server. There are two types of Illinois 30 Day Summons: the Summons in Forcible Entry and Detained and the Summons in Garnishment or Other Proceedings. The Summons in Forcible Entry and Detained is issued when a landlord seeks to evict a tenant for failing to pay rent or failing to comply with the terms of a lease. The Summons in Garnishment or Other Proceedings is issued when a creditor seeks to collect a debt or enforce a judgment. Both types of summons require the defendant to appear in court or comply with the order within 30 days of the date of service. Failure to do so could result in a default judgment being entered against them.
