Illinois Summons/alias Summons is a legal document served to a defendant in a civil lawsuit in the State of Illinois. The document is used to inform the defendant of the lawsuit and require them to appear in court to answer the complaint. There are two types of Illinois Summons/alias Summons: the ordinary Summons and the alias Summons. An ordinary Summons is a document that is served on the defendant to alert them of the lawsuit. It typically contains the time, date, and location of the court hearing and the name of the plaintiff and defendant involved in the case. It also usually includes a copy of the complaint. An alias Summons is a document that is served when the defendant cannot be found in order to inform them of the lawsuit. This document is usually served through publication and is often used if the defendant's address is unknown or if the defendant is out of state. The alias Summons will include the same information as an ordinary Summons, but will also include the instructions for how to answer the complaint.
