Illinois Paternity Summons is a legal document issued by an Illinois court in order to establish the legal parentage of a child. This document is generally used when a child is born out of wedlock, and there is a need to prove that a certain person is the biological father of the child. Depending on the nature of the case, Illinois Paternity Summons may be issued in two forms: a Summons of Genetic Testing or a Summons of Paternity. A Summons of Genetic Testing is generally issued if the alleged father denies that he is the biological father of the child. In this case, the court will order the alleged father and the child to undergo genetic testing to establish the paternity of the child. A Summons of Paternity is issued if the alleged father does not deny that he is the biological father of the child. In this case, the court will order the alleged father to attend a hearing, where the paternity of the child will be legally established. Both types of Illinois Paternity Summons serve to establish the legal parentage of a child, and provide the child with rights and benefits that come with legally recognized parentage.
