Illinois Final and Irrevocable Consent To Adoption is a legal document that is necessary for a successful adoption in the state of Illinois. This document grants parental rights to the adoptive parents or agency and terminates the rights of the birth parent or parents. In order for a Final and Irrevocable Consent to Adoption to be valid, it must be signed by the birth parent or parents and witnessed by two people. Additionally, the document must be filed with the court prior to the adoption being finalized. There are two types of Final and Irrevocable Consent to Adoption in Illinois: Voluntary and Involuntary. Voluntary Consent is granted by a birth parent who voluntarily agrees to terminate their parental rights. Involuntary Consent can be granted if the birth parent is found to be unfit to parent, or if the birth parent has abandoned the child. In either case, the birth parent must sign the document in front of two witnesses and file it with the court. Once the Final and Irrevocable Consent is filed, the adoption process can move forward. The adoptive parents will be granted legal rights to the child and the birth parent or parents will no longer have any legal claim to the child.
