    "IN THE MATTER OF NOTICE TO ....., PUTATIVE FATHER.
    You have been identified as the father of a child born or expected to be born on or about (insert date).
    The mother of the child is.....
    The mother has indicated that she intends to place the child for adoption.
    As the alleged father of the child, you have certain legal rights with respect to the child, including the right to notice of the filing of proceedings instituted for the adoption of the child. If you wish to retain your rights with respect to the child, you must file with the Clerk of this Circuit Court of .... County, Illinois, whose address is ...., Illinois, within 30 days after the date of receipt of this notice, the declaration of paternity enclosed herewith stating that you are, in fact, the father of the child and that you intend to retain your legal rights with respect to the child, or request to be notified of any further proceedings with respect to custody or adoption of the child.
    If you do not file such a declaration of paternity, or a request for notice, then whatever legal rights you have with respect to the child, including the right to notice of any future proceedings for the adoption of the child, may be terminated without any further notice to you. When your legal rights with respect to the child are so terminated, you will not be entitled to notice of any proceeding instituted for the adoption of the child.
    If you are not the father of the child, you may file with the Clerk of this Court the disclaimer of paternity enclosed herewith which will be noted in the Clerk's file and you will receive no further notice with respect to the child."
    The declaration of paternity shall be substantially as follows:

I hereby consent to the adoption of this child, and waive any rights, remedies and defenses that I may now or in the future have as a result of the mother's allegation of the paternity of this child. This consent is being given in order to facilitate the adoption of the child and so that the court may terminate what rights I may have to the child as a result of being named the father by the mother. This consent is not in any manner an admission of paternity.
    (5) I hereby enter my appearance in the above entitled cause and waive service of summons and other pleading.
