Article I. General Rules · Last amended 1992 · Last verified July 20, 2026
In one sentenceRule 100.3 lists which child support, medical support, and parentage cases a circuit's plan can send to an administrative hearing officer instead of a judge.
(a)Eligible Actions. The following actions, if so provided for in the Plan, are eligible to be
heard by an administrative hearing officer:
(1)actions pursuant to the Illinois Public Aid Code, as amended, to establish temporary
and final child support and medical support, and to enforce or modify existing orders of child support and medical support;
(2)actions pursuant to the Illinois Parentage Act of 1984, as amended, to establish a parent and child relationship; to establish child support and medical support after parentage has been acknowledged or established, whether or not these issues were reserved at the time judgment was entered; and to enforce or modify existing child support and medical support orders;
(3)actions pursuant to the Illinois Marriage and Dissolution of Marriage Act, as amended, to establish temporary and final child support and medical support, whether or not these issues were reserved or could not be ordered at the time judgment was entered because the court lacked personal jurisdiction over the obligor; and to enforce or modify existing orders of child support and medical support;
(4)actions pursuant to the Nonsupport of Spouse and Children Act to establish temporary child support and to enforce and modify such orders;
(5)actions pursuant to the Revised Uniform Reciprocal Enforcement of Support Act to establish temporary and final child support and medical support, whether or not these issues were reserved or could not be ordered at the time judgment was entered because the court lacked personal jurisdiction over the obligor; and to enforce and modify existing child support and medical support orders; and
(6)any other child support or medical support matter.
(b)Other Eligible Prejudgment Proceedings. If provided for in the Plan, the System may be available in prejudgment proceedings for dissolution of marriage, declaration of invalidity of marriage and legal separation.
Plain-English Summary
Rule 100.3 draws the boundary around what an administrative hearing officer is allowed to handle. If a circuit's plan says so, hearing officers can take cases under the Public Aid Code, the Parentage Act, the Marriage and Dissolution of Marriage Act, the Nonsupport of Spouse and Children Act, and the reciprocal enforcement of support laws, covering everything from establishing paternity and setting first-time support orders to enforcing or modifying support that's already in place.
A circuit can also let the System handle certain prejudgment matters before a divorce, annulment, or legal separation is finalized, again only if the plan specifically allows it. The rule doesn't force every eligible case into this track; it only lists what's allowed if the local plan opts in.
Frequently Asked Questions
Can an administrative hearing officer decide who the legal father of a child is?
Yes, if the circuit's plan allows it, hearing officers can handle parentage actions under the Illinois Parentage Act of 1984.
Can a child support order be modified through the expedited system?
Yes, modifying existing child support and medical support orders is one of the eligible actions listed in Rule 100.3.
Does Rule 100.3 cover spousal maintenance?
No. Spousal maintenance is a domestic relations matter that Rule 100.9 sends to a judge rather than an administrative hearing officer, even in a dissolution or legal separation case the System is otherwise handling for child support or parentage.
Is a hearing officer required to hear every eligible case type?
No, the circuit's plan decides which of the listed action types go to a hearing officer.
What laws give rise to cases eligible for expedited hearings?
The Public Aid Code, the Parentage Act, the Marriage and Dissolution of Marriage Act, the Nonsupport of Spouse and Children Act, and the Revised Uniform Reciprocal Enforcement of Support Act.
