Illinois Denial of Paternity With Entry Of Appearance and Consent To Adopt is a legal proceeding that occurs when the biological father of a child denies paternity and allows the child to be adopted by another person. This type of process can occur before or after the child is born. There are two types of Illinois Denial of Paternity With Entry Of Appearance and Consent To Adopt: 1. Voluntary Denial of Paternity: This type of denial occurs when the biological father voluntarily waives his parental rights. The father must sign a document legally denying paternity and consenting to the adoption. 2. Court-Ordered Denial of Paternity: This type of denial occurs when the biological father is found by a court to be unfit to be a parent. The court will then issue an order revoking the biological father's rights and consenting to the adoption. In either case, the biological father must appear in court to enter a formal denial of paternity and consent to the adoption. The father must also provide sufficient evidence proving that he is the biological father of the child. After the father's denial and consent have been entered in court, the adoption can proceed.
