In re Marriage of W.

Overview

In re Marriage of Tyler W. v. Sarah W. (Janai P.) , 2026 IL App (4th) 251315-U, is a Rule 23 order in which the Fourth District affirmed the trial court's allocation of majority parenting time and sole significant decision-making authority to the father. The appellate court found the mother forfeited all three of her claims—due process, manifest weight of the evidence, and constitutional violations—due to pervasive noncompliance with Illinois Supreme Court Rule 341(h) briefing requirements.

Key Facts

Parties married in 2001; two children born 2006 (E.W.) and 2011 (L.W.). Only L.W. remained a minor at the time of the parenting determination.

Tyler was represented by counsel throughout; Sarah proceeded pro se, briefly retained counsel mid-hearing, then discharged counsel before the court's ruling.

Four evidentiary hearings were held (January–September 2025). Sarah's attorney rested without presenting all evidence Sarah wanted; Sarah then sought to discharge counsel.

The trial court granted Tyler sole significant decision-making (education and medical) and majority parenting time; Sarah received a six-week reunification period followed by every-other-weekend parenting time.

Sarah never filed a proposed parenting plan despite repeated court reminders.

Procedural History

Knox County Circuit Court (Judge Baber). Marriage dissolved May 2024; parenting issues reserved. October 2025 written order allocated parenting responsibilities. Sarah's motion to reconsider/vacate was denied. Appeal filed December 5, 2025, to the Fourth District. The appeal was initially dismissed for failure to file a docketing statement, reinstated January 27, 2026, and decided beyond the Rule 311(a)(5) 150-day deadline, with good cause found for the delay.

Holdings

All three claims forfeited. The court held Sarah's appellant's brief contained multiple fatal deficiencies under Rule 341(h)—no introductory paragraph (h)(2), no standards of review with citation (h)(3), no record citations in the statement of facts (h)(6), and no developed legal argument with authority (h)(7). No standard of review was reached on the merits.

Motions for late reply brief and supplemental reply brief were denied as further briefing would not assist the court given the forfeiture.

Legal Principles

Rule 341(h) (eff. Oct. 1, 2020): Briefing rules "have the force of law." Billerbeck v. Caterpillar Tractor Co. , 292 Ill. App. 3d 350, 353 (1997); Niewold v. Fry , 306 Ill. App. 3d 735, 737 (1999).

Pro se litigants are held to the same standards as attorneys. Steinbrecher v. Steinbrecher , 197 Ill. 2d 514, 528 (2001).

The appellate court is "not a depository" for undeveloped arguments. In re Marriage of Hundley , 2019 IL App (4th) 180380, ¶ 82; In re N.F. , 2020 IL App (1st) 182427, ¶ 30.

Rule 311(a)(5) : Custody cases require expedited disposition within 150 days; delay permitted for good cause.

Practical Implications

Appellees facing deficient briefs should affirmatively raise Rule 341(h) forfeiture—this case shows courts will enforce it comprehensively, even in child-custody appeals.

Pro se opponents: Document every instance of noncompliance with briefing rules; the court will not search the record for error on the appellant's behalf.

Trial counsel: Ensure a proposed parenting plan is filed. The court noted Sarah's failure to file one despite repeated reminders, undermining her constitutional argument on appeal.

Preserving issues: When a client discharges counsel mid-hearing, consider filing a post-trial motion with specific factual detail about excluded evidence and witnesses to preserve due process claims.

Distinguishing this case: Because the court never reached the merits, this opinion provides no guidance on the substantive standards for allocating sole decision-making or reunification parenting-time schedules.

Limitations/Caveats

This is a Rule 23 order , not precedent except in the limited circumstances allowed under Rule 23(e)(1). The entire disposition rests on procedural forfeiture ; the court issued no merits ruling on due process, manifest weight, or constitutional claims—all reasoning on those points is effectively dicta . The case cannot be cited for the proposition that the trial court's parenting allocation was correct on the merits.
