Illinois Notice To Putative Father is a legal notice that is sent to an unmarried man who may be the father of a child born to a woman in Illinois. It informs him of his rights and obligations in relation to the child and the adoption process. The notice is issued only after the birth mother has signed a consent to adoption. There are two types of Illinois Notice To Putative Father: the Voluntary Acknowledgement of Paternity form and the Notice of Intent to Relinquish Parental Rights. The Voluntary Acknowledgement of Paternity form allows a father to officially recognize himself as the biological father of a child before the adoption is finalized. The Notice of Intent to Relinquish Parental Rights informs the putative father that the birth mother has decided to put the child up for adoption and that he must take action in order to have his parental rights preserved. Both forms must be signed by the putative father and filed with the court before the adoption can be finalized.
