Background

Katelyn Jill Tate and Roger Dale Tate, Jr., are the parents of two minor children. After Mother petitioned for dissolution, the parties agreed to a temporary schedule under which Father had alternating weekends, Tuesday and Thursday evenings, designated holidays, and two nonconsecutive summer weeks, while Mother had the remaining parenting time. They shared decision-making authority.

At trial, the evidence showed that both parents had good relationships with the children and could care for them, but Mother historically performed most day-to-day caretaking. She worked locally as a teacher and managed school matters, medical appointments, and one child’s individualized education plan. Father sought equal parenting time, while the guardian ad litem recommended increasing his share to approximately 45%. The circuit court instead largely continued the existing school-year schedule, added overnight Tuesday and Thursday visits during summer, preserved joint decision-making, and awarded Mother the majority of parenting time.

Father appealed pro se, challenging the court’s treatment of the guardian ad litem’s evidence, the temporary order, the parties’ caretaking histories, his school involvement, and evidence of domestic violence. Mother sought sanctions, alleging that Father’s appellate brief used authorities that did not support its propositions and may have been prepared using artificial intelligence.

The Court’s Holding

The appellate court affirmed. Because the judge who entered the parenting order had not presided over the evidentiary hearing and decided the matter from transcripts, the appellate court was inclined to review the record de novo, although it concluded that the result would be the same under the traditional manifest-weight or abuse-of-discretion standards.

After independently reviewing the record, the court held that awarding Mother a majority of parenting time served the children’s best interests. The circuit court considered the relevant statutory factors, including Mother’s longstanding role as primary caretaker, the prior agreed schedule, the children’s needs and preferences, Father’s limited knowledge of school and IEP matters, and evidence concerning the 2021 domestic-violence incident. The court also held that allocating Father less parenting time was not a statutory “restriction” on parenting time.

The appellate court denied Mother’s sanctions motion. Although Father’s brief cited cases that often did not support his propositions, the deficiencies did not hinder review, Mother supplied a cogent brief, and Father otherwise substantially complied with the appellate rules. The court nevertheless urged him to avoid similar noncompliance in the future.

Key Takeaways

  • A parenting-time allocation will be upheld when the record shows that the court considered the relevant statutory best-interest factors and its findings are supported by the evidence.
  • A prior temporary parenting agreement and each parent’s historical performance of caretaking functions are relevant, even though a temporary order does not predetermine the final allocation.
  • A smaller share of parenting time is not, by itself, a statutory restriction on parenting time.
  • Unsupported or inaccurate citations can violate appellate briefing rules, but striking a brief or dismissing an appeal is generally reserved for violations that hinder meaningful review.

Why It Matters

The order illustrates that Illinois courts may deviate from a guardian ad litem’s proposed schedule when the statutory factors support a different arrangement. A parent’s demonstrated involvement in education, healthcare, routines, and special needs can carry substantial weight, while joint decision-making does not require equal parenting time.

The decision also cautions self-represented litigants that suspected AI assistance does not excuse inaccurate legal citations. Although sanctions were denied here, litigants remain responsible for verifying that cited authorities actually support their arguments.
