(750 ILCS 5/603.10)
    Sec. 603.10. Restriction of parental responsibilities.
    (a) After a hearing, if the court finds by a preponderance of the evidence that a parent engaged in any conduct that seriously endangered the child's mental, moral, or physical health or that significantly impaired the child's emotional development, the court shall enter orders as necessary to protect the child. Such orders may include, but are not limited to, orders for one or more of the following:
        (1) a reduction, elimination, or other adjustment of
    
the parent's decision-making responsibilities or parenting time, or both decision-making responsibilities and parenting time;
        (2) supervision, including ordering the Department of
    
Children and Family Services to exercise continuing supervision under Section 5 of the Children and Family Services Act;
        (3) requiring the exchange of the child between the
    
parents through an intermediary or in a protected setting;
        (4) restraining a parent's communication with or
    
proximity to the other parent or the child;
        (5) requiring a parent to abstain from possessing or
    
consuming alcohol or non-prescribed drugs while exercising parenting time with the child and within a specified period immediately preceding the exercise of parenting time;
        (6) restricting the presence of specific persons
    
while a parent is exercising parenting time with the child;
        (7) requiring a parent to post a bond to secure the
    
return of the child following the parent's exercise of parenting time or to secure other performance required by the court;
        (8) requiring a parent to complete a treatment
    
program for perpetrators of abuse, for drug or alcohol abuse, or for other behavior that is the basis for restricting parental responsibilities under this Section; and
        (9) any other constraints or conditions that the
    
court deems necessary to provide for the child's safety or welfare.
    (b) The court may modify an order restricting parental responsibilities if, after a hearing, the court finds by a preponderance of the evidence that a modification is in the child's best interests based on (i) a change of circumstances that occurred after the entry of an order restricting parental responsibilities; or (ii) conduct of which the court was previously unaware that seriously endangers the child. In determining whether to modify an order under this subsection, the court must consider factors that include, but need not be limited to, the following:
        (1) abuse, neglect, or abandonment of the child;
        (2) abusing or allowing abuse of another person that
    
had an impact upon the child;
        (3) use of drugs, alcohol, or any other substance in
    
a way that interferes with the parent's ability to perform caretaking functions with respect to the child; and
        (4) persistent continuing interference with the other
    
parent's access to the child, except for actions taken with a reasonable, good-faith belief that they are necessary to protect the child's safety pending adjudication of the facts underlying that belief, provided that the interfering parent initiates a proceeding to determine those facts as soon as practicable.
    (c) An order granting parenting time to a parent or visitation to another person may be revoked by the court if that parent or other person is found to have knowingly used his or her parenting time or visitation to facilitate contact between the child and a parent who has been barred from contact with the child or to have knowingly used his or her parenting time or visitation to facilitate contact with the child that violates any restrictions imposed on a parent's parenting time by a court of competent jurisdiction. Nothing in this subsection limits a court's authority to enforce its orders in any other manner authorized by law.
    (d) If parenting time of a parent is restricted, an order granting visitation to a non-parent with a child or an order granting parenting time to the other parent shall contain the following language:
        "If a person granted parenting time or visitation
    
under this order uses that time to facilitate contact between the child and a parent whose parenting time is restricted, or if such a person violates any restrictions placed on parenting time or visitation by the court, the parenting time or visitation granted under this order shall be revoked until further order of court."
    (e) A parent who, after a hearing, is determined by the court to have been convicted of any offense involving an illegal sex act perpetrated upon a victim less than 18 years of age, including but not limited to an offense under Article 11 of the Criminal Code of 2012, is not entitled to parenting time while incarcerated or while on parole, probation, conditional discharge, periodic imprisonment, or mandatory supervised release for a felony offense, until the parent complies with such terms and conditions as the court determines are in the child's best interests, taking into account the exact nature of the offense and what, if any, treatment in which the parent successfully participated.
    (f) A parent may not, while the child is present, visit any person granted visitation or parenting time who has been convicted of first degree murder, unless the court finds, after considering all relevant factors, including those set forth in subsection (b) of Section 602.7, that it would be in the child's best interests to allow the child to be present during such a visit.
