Key Takeaways
- 1 Illinois retains UIFSA modification jurisdiction when nonresident party consents through litigation conduct.
- 2 Failure to provide a report of proceedings triggers Foutch presumption, defeating appellate challenges to factual findings.

Summary
The parties divorced in Cook County in 2020 with three children. All parties subsequently relocated—respondent and the children to Michigan, petitioner to Georgia. In 2024, respondent filed a motion to modify child support in Cook County. Following an evidentiary hearing, the circuit court found a substantial change of circumstances, modified petitioner's support obligation upward, and ordered payment of arrearages and unreimbursed expenses. Petitioner, appearing pro se, appealed, raising challenges to Illinois jurisdiction under UIFSA, the court's modification of the dissolution judgment's true-up and receipts provisions, and the adequacy of the court's written findings supporting the modified support amount.
The appellate court affirmed on all issues. On jurisdiction, the court held that UIFSA section 205 does not implicate subject matter jurisdiction, which is constitutionally conferred. Although personal jurisdiction under UIFSA requires consent when all parties reside outside Illinois, petitioner waived any objection by filing an appearance, answer, and affirmative defenses and fully participating in proceedings without raising a timely challenge under 735 ILCS 5/2-301(a-6). His conduct also independently constituted affirmative consent.
On the merits, the court's analysis was largely controlled by petitioner's failure to include a report of proceedings in the appellate record. Under Foutch v. O'Bryant, the appellate court presumed the circuit court's factual findings—including that respondent submitted required receipts and that a substantial change of circumstances existed—were supported by the evidence. The court also confirmed that a substantial change in circumstances may rest solely on an increase in the supporting parent's income, and that no additional written findings are required when the court applies guideline support without deviation.
Key Holdings
1. UIFSA section 205 compliance does not affect a circuit court's subject matter jurisdiction, which is conferred solely by the Illinois Constitution; statutory references to 'jurisdiction' impose only procedural limits. 2. A party waives personal jurisdiction objections under UIFSA by filing an appearance and responsive pleadings and participating in evidentiary proceedings without raising a timely challenge under 735 ILCS 5/2-301(a-6); such conduct also constitutes affirmative consent to continuing Illinois jurisdiction. 3. A circuit court's removal of an income tax return exchange requirement from a dissolution judgment constitutes a modification—not a clarification—of that judgment, but is authorized upon a finding of substantial change of circumstances under 750 ILCS 5/510(a)(1). 4. Where an appellant fails to provide a report of proceedings, the appellate court applies the Foutch presumption that the circuit court's decision was supported by the evidence, precluding reversal of factual findings on child support modification.
