Illinois adoption Summons is a document issued by an Illinois court to a parent or guardian in a pending adoption case. This summons informs the parent or guardian of the date and time of the hearing, the name of the petitioner (the person who filed the petition), the court location, the case number, and the rights of the parent or guardian. There are two types of Illinois adoption summons: a summons to appear in court and a summons to provide information. The summons to appear in court directs the parent or guardian to attend the adoption hearing, while the summons to provide information directs the parent or guardian to provide certain information to the court.
