Citation: N/A Court: Illinois Appellate Court Date: August 18, 2025

Facts

Aaron and Amy McLean divorced in St. Clair County, with disputes over Aaron's 401(k) accounts and parental responsibility allocation. The trial court divided the retirement accounts and allocated parenting time, but Amy appealed both determinations.

Issue

Whether the trial court properly calculated marital versus nonmarital portions of retirement accounts and whether the parental responsibility allocation was appropriate.

Holding

The appellate court vacated the retirement account division due to improper calculation of marital and nonmarital portions, requiring recalculation with proper documentation. The parental responsibility allocation was affirmed as supported by evidence and within the trial court's discretion.

Key Reasoning

  • Courts must trace marital versus nonmarital contributions in retirement accounts using coverture fractions or equivalent methods with proper documentation
  • Trial court's calculation was unsupported by the record regarding post-separation contributions, employer matches, and rollovers
  • Parental responsibility allocations receive deferential review based on best interest factors and credibility assessments
  • Evidence supported the trial court's parenting time allocation despite contested facts about compliance and incidents

Practical Impact

For Petitioners

Build comprehensive evidentiary records for retirement accounts including contribution histories, employment dates, and expert testimony to avoid remand

For Respondents

Challenge incomplete retirement account calculations and rely on appellate deference for parenting time allocations when trial court properly considered evidence

When This Applies

Applies when retirement accounts have mixed marital and nonmarital contributions; limited application to cases with simple, fully marital accounts
