Illinois Alias Summons is a court-issued document in the state of Illinois that orders an individual to appear in court and answer to a legal complaint. An Alias Summons is typically issued when the defendant has failed to respond to a previous court summons. There are two types of Illinois Alias Summons: a Standard Alias Summons and a Special Alias Summons. The Standard Alias Summons requires the defendant to appear in court on a certain date to answer to the complaint. The Special Alias Summons allows the defendant to either appear in court on a certain date or submit a written answer to the complaint. Upon receipt of the Alias Summons, the defendant has 20 days to appear in court or submit a written answer to the complaint. If the defendant fails to comply with the Alias Summons, they may be found in contempt of court.
