Parenting-Time-Only Modifications Require Changed Circumstances, Not a Substantial Change

Case: Reynolds v. Reynolds, 2026 IL 132627

Court: Supreme Court of Illinois

Date: September 24, 2026

Introduction

Reynolds v. Reynolds resolves an Illinois appellate-court conflict over the standard for modifying parenting time under section 610.5 of the Illinois Marriage and Dissolution of Marriage Act. The court held that a parent seeking to modify parenting time alone need not prove a substantial or unanticipated change in circumstances. Section 610.5(a) requires only changed circumstances that necessitate modification to serve the child’s best interests.

Nancy Reynolds and Christopher I. Reynolds Sr., who never married, had a 2016 agreed allocation judgment concerning their daughters, D.R. and E.R. Nancy received primary parenting time and significant decision-making responsibilities, while Christopher received specified weekly and alternating-weekend parenting time.

Christopher later sought additional parenting time, citing remote employment, a larger home, the children’s increased ages, their relationships with half-siblings, and D.R.’s autism diagnosis. The circuit court granted Nancy’s motion for a directed finding because Christopher had not established a substantial change in circumstances under section 610.5(c). The central issue was whether subsection (c) supplied the governing standard or whether the less demanding language of subsection (a) controlled.

Summary of the Opinion

The Illinois Supreme Court unanimously affirmed the appellate court, reversed the circuit court, and remanded the case. It held:

  • Section 610.5(a) governs motions seeking modification of parenting time alone.
  • The moving parent must show changed circumstances that necessitate modification to serve the child’s best interests.
  • The parent need not prove that the changes were substantial or unanticipated.
  • Section 610.5(c)’s substantial-change standard applies to modifications of parenting plans or allocation judgments beyond a parenting-time-only request.
  • In re Marriage of Trapkus was overruled to the extent it required parenting-time modifications to satisfy subsection (c).

The Supreme Court did not award Christopher additional parenting time. It directed the circuit court to determine whether the changes he proved actually necessitate modification in the children’s best interests. If his evidence survives Nancy’s directed-finding motion under that standard, Nancy must be allowed to present her case.

Analysis

1. Statutory Framework

Section 610.5(a) treats significant decision-making responsibilities and parenting time differently. A motion to modify decision-making responsibilities ordinarily cannot be filed within two years of the governing order unless affidavits indicate serious endangerment or significant emotional impairment. Parenting time, by contrast, may be modified at any time upon:

  1. a showing of changed circumstances;
  2. a showing that those circumstances necessitate modification; and
  3. a determination that modification serves the child’s best interests.

Section 610.5(c) permits modification of a parenting plan or allocation judgment when a substantial change has occurred in the circumstances of the child or either parent, based on postjudgment or previously unanticipated facts, and modification is necessary to serve the child’s best interests.

2. Legal Reasoning

Plain language controls

The court began with the statute’s language as the best evidence of legislative intent. Subsection (a) expressly states both when parenting time may be modified and what must be shown. Because that language is clear, the court declined to add a requirement that the change be substantial or unanticipated.

Parenting time is intentionally treated differently

Subsection (a) expressly excludes parenting time from the restrictions governing decision-making responsibilities and then provides a separate parenting-time standard. This structure demonstrated a legislative choice to make parenting-time orders more readily modifiable than significant decision-making allocations.

Statutory definitions do not erase the specific rule

Nancy argued that parenting time is part of both “parental responsibilities” and a “parenting plan,” meaning any modification necessarily falls under subsection (c). The court acknowledged that the definitions in section 600 are broad enough, standing alone, to reach parenting time. Nevertheless, subsection (a) specifically establishes the standard for parenting-time modifications. The definitions therefore could not be used to nullify that express provision.

A contrary interpretation would make subsection (a) meaningless

If every parenting-time modification also had to satisfy subsection (c), subsection (a)’s changed-circumstances language would perform no independent function. Courts must avoid statutory interpretations that render words superfluous. The only meaningful reading is that subsection (a) itself supplies the substantive standard for parenting-time-only motions.

The statute was not rendered ambiguous by judicial disagreement

The appellate districts and the appellate dissent had reached competing interpretations. The Supreme Court explained that disagreement among judges may suggest ambiguity, but it is not dispositive. After examining the statutory text and structure, the court found the operative language sufficiently clear.

3. Application to the Evidence

The circuit court had found that changes occurred but rejected them as insufficiently substantial or as anticipated when the 2016 judgment was entered. Those additional requirements came from subsection (c) and should not have been applied.

Christopher presented evidence that:

  • he had changed from office-based employment to remote work;
  • he had moved to a larger residence closer to the children’s schools;
  • the children were older and attending school;
  • the children had developed relationships with half-siblings in his household;
  • D.R. had been diagnosed with autism and had bonded with a half-brother who had the same diagnosis; and
  • school-based exchanges could reduce transitions and parental interaction.

Indeed, the circuit court expressly stated that changes had been proved. Once the improper requirements of substantiality and unforeseeability were removed, the decision granting a directed finding was against the manifest weight of the evidence. The remaining question is whether the proven changes make additional parenting time necessary to serve D.R.’s and E.R.’s best interests.

4. Precedents Cited

People ex rel. Sherman v. Cryns

This case supplied the two-step framework for a motion for a directed finding. First, the court determines whether the nonmoving party has presented a prima facie case. If so, the court then weighs all the evidence, evaluates credibility, and draws reasonable inferences. Because the circuit court in Reynolds reached the second step, its factual determination was reviewed under the manifest-weight standard.

In re Estate of Coffman

The court relied on this decision for manifest-weight review and for the principle that a judgment is against the manifest weight of the evidence when the opposite conclusion is apparent or the judgment is arbitrary, unreasonable, or unsupported by the evidence.

In re Marriage of Dynako

This precedent established that statutory interpretation is a question of law reviewed de novo. It also reinforced the rule that clear statutory language must be applied as written without adding exceptions, limitations, or conditions.

County of Du Page v. Illinois Labor Relations Board

The court cited this case for the whole-statute rule: statutory words cannot be interpreted in isolation but must be read alongside related provisions and within the statute’s overall structure.

Ready v. United/Goedecke Services, Inc.

This case provided the definition of statutory ambiguity and explained that conflicting lower-court interpretations may indicate ambiguity but do not establish it automatically.

In re C.C.

This decision supported the presumption that, when the legislature includes particular language in one statutory provision but omits it from another, the difference is intentional. The express parenting-time language in subsection (a), contrasted with its omission from subsection (c), was therefore significant.

Mercado v. S&C Electric Co. and Palm v. Holocker

These cases reinforced two interpretive rules: courts may not add restrictions that conflict with clear legislative intent, and they should not interpret a statute so that any portion becomes meaningless or superfluous.

In re Marriage of Trapkus

Trapkus had treated subsection (a) as merely a gateway to an evidentiary hearing governed by subsection (c), thereby imposing the substantial-change standard on parenting-time requests. The Supreme Court rejected that analysis because Trapkus consulted legislative history without first finding the statute ambiguous and failed to give effect to subsection (a)’s express language. It was overruled to the extent inconsistent with Reynolds.

Department of Public Aid ex rel. Davis v. Brewer

Trapkus had relied on this decision concerning an earlier version of the modification statute. The Supreme Court found it distinguishable because it interpreted former sections 610(a) and (b), particularly in the context of custody motions filed within two years. It did not control the materially different current language of section 610.5.

Petersen v. Wallach

This case supported the rule that legislative history should not displace the plain meaning of unambiguous statutory text.

In re Marriage of Salbi and Erik S. v. Hollie S.

These unreported appellate decisions had interpreted subsection (a) to require changed circumstances, rather than a substantial change, for parenting-time modifications. Their reasoning aligned with the Supreme Court’s interpretation and illustrated the appellate conflict resolved by Reynolds.

Impact

Reynolds establishes a uniform statewide standard and lowers the threshold for obtaining judicial consideration of a parenting-time-only modification. Parents no longer must characterize ordinary developments—such as changed work arrangements, children entering school, relocation, or evolving family relationships—as “substantial” or “unanticipated.”

The decision does not make parenting-time modifications automatic. A parent must still prove both changed circumstances and a connection between those circumstances and a modification necessary for the child’s best interests. Courts remain able to reject requests based on insignificant changes that do not justify altering the child’s schedule.

The ruling also encourages courts to distinguish carefully between requests involving parenting time alone and requests involving significant decision-making authority or broader revisions to an allocation judgment. It further confirms that precedents interpreting earlier statutory language cannot override the plain text of the current Act.

Complex Concepts Simplified

Parenting time
The periods during which a parent is responsible for caring for and spending time with a child.
Significant decision-making responsibilities
Authority over major matters such as education, health care, religion, and extracurricular activities.
Allocation judgment
A court judgment assigning parental responsibilities, including parenting time and significant decision-making authority.
Changed circumstances
Relevant developments occurring after the prior order. Under subsection (a), they need not be substantial or unanticipated.
Best interests of the child
The controlling child-centered inquiry into whether a proposed arrangement promotes the child’s welfare, stability, development, and relationships.
Prima facie case
Enough evidence, if initially accepted, to support the requested relief and require further consideration.
Directed finding
A ruling in a bench trial that ends the opposing party’s claim after that party presents evidence because the proof is legally or factually insufficient.
De novo review
Independent appellate review of a legal question, without deference to the lower court’s interpretation.
Manifest weight of the evidence
A deferential standard under which reversal is appropriate when the opposite conclusion is apparent or the ruling is arbitrary, unreasonable, or unsupported.

Conclusion

Reynolds v. Reynolds definitively separates parenting-time-only modifications from the substantial-change standard applicable under section 610.5(c). Under section 610.5(a), the moving parent must establish changed circumstances that necessitate modification in the child’s best interests—but not a substantial or unanticipated change.

By enforcing the statutory distinction, preventing subsection (a) from becoming meaningless, and overruling In re Marriage of Trapkus in part, the decision provides important clarity for Illinois parents and courts. Its practical significance lies in allowing parenting-time orders to respond to evolving family circumstances while preserving the child’s best interests as the ultimate safeguard.
