Must Utah courts hold separate hearings for custody modification issues? Doyle v. Doyle Explained

In custody modification proceedings, practitioners often debate whether Utah courts must conduct separate hearings for the substantial change in circumstances analysis and the best interests determination. The Utah Court of Appeals clarified this procedural requirement in Doyle v. Doyle, addressing a father’s challenge to the trial court’s combined hearing approach.

Background and Facts

Following divorce, father received sole custody while mother lived in Colorado. The decree included a provision for automatic joint custody if mother relocated to Salt Lake Valley. When mother moved back and invoked this provision, father successfully challenged it under Rule 60(b). Mother then petitioned to modify custody, arguing substantial changes included her relocation, the invalidated joint custody provision, and the child’s need for stability. Father moved to bifurcate the hearing into separate proceedings for changed circumstances and best interests, but the trial court granted only analytical bifurcation while conducting a combined evidentiary hearing.

Key Legal Issues

The court addressed whether Utah law requires complete procedural bifurcation of custody modification hearings, with separate evidence presentation for each analytical prong. Father argued that allowing best interests evidence before determining substantial change constituted reversible error and created unfair prejudice.

Court’s Analysis and Holding

The Court of Appeals affirmed that while Utah law requires analytical bifurcation under Hogge v. Hogge, it does not mandate separate hearings. The court emphasized that “it is the bifurcation of the analysis–not the literal bifurcation of the proceedings–that matters.” Trial courts retain discretion under Rule 611(a) to control evidence presentation mode and order. The court noted that evidence often overlaps between both determinations, making separate hearings potentially wasteful and duplicative. The trial court properly maintained analytical separation while efficiently managing overlapping evidence.

Practice Implications

This decision provides important guidance for custody modification practice. Attorneys cannot successfully challenge proceedings based solely on combined hearings if the trial court maintains proper analytical bifurcation. However, practitioners should ensure trial courts make clear findings on substantial change before proceeding to best interests analysis. The ruling also confirms that child support modifications may follow custody changes under Rule 54(c)(1) even without specific requests, and that social security disability benefits must be credited only against the earning parent’s obligation under Utah Code § 78B-12-203(8)(b).
