325 ILCS 2/30
If there is no evidence of abuse or neglect of a relinquished newborn infant, the relinquishing person has the right to remain anonymous and to leave the hospital, police station, fire station, or emergency medical facility at any time and not be pursued or followed. Before the relinquishing person leaves the hospital, police station, fire station, or emergency medical facility, the hospital, police station, fire station, or emergency medical facility personnel shall (i) verbally inform the relinquishing person that by relinquishing the child anonymously, the relinquishing person will have to petition the court if the relinquishing person desires to prevent the termination of parental rights and regain custody of the child and (ii) offer the relinquishing person the information packet described in Section 35 of this Act. However, nothing in this Act shall be construed as precluding the relinquishing person from providing the relinquishing person's identity or completing the application forms for the Illinois Adoption Registry and Medical Information Exchange and requesting that the hospital, police station, fire station, or emergency medical facility forward those forms to the Illinois Adoption Registry and Medical Information Exchange.
