Illinois Finding Regarding Paternity is a legal document issued by the state of Illinois to establish the paternity of a child. It is also known as an Illinois Declaration of Paternity. This document is used to establish the legal father of a child and to provide the father with rights and responsibilities to the child. The most common types of Illinois Finding Regarding Paternity are voluntary acknowledgments of paternity, adjudications of paternity, and court orders. A voluntary acknowledgment of paternity can be completed by both parents without a court order. An adjudication of paternity is a court order that establishes the paternity of a child. Finally, a court order is issued by a court following a hearing, and is used to establish the paternity of a child, as well as to provide the father with parental rights and responsibilities.
