Can Utah courts calculate child support based on future potential custody arrangements? Stephens v. Stephens Explained

In Stephens v. Stephens, the Utah Court of Appeals addressed whether child support calculations should be based on current custody arrangements or potential future arrangements under step-up parenting plans. The case provides important guidance for practitioners handling complex custody modifications involving domestic violence and gradual reunification.

Background and Facts

The parties divorced in 2011 with Father receiving sole physical custody and Mother awarded liberal parent-time exceeding 30% overnight stays. Four years later, Father petitioned to modify the decree based on Mother’s abuse of their child, supported by a DCFS finding and testimony from the child describing physical violence and emotional abuse. The district court implemented a step-up plan allowing Mother to gradually regain her original parent-time over six weeks, contingent on her refraining from further abusive behavior.

Key Legal Issues

The case presented two primary issues: (1) whether the modified decree entitled Mother to joint physical custody designation based on potential future overnight stays exceeding 30% per year, and (2) whether child support calculations should use joint custody worksheets when the arrangement might eventually qualify for joint custody. Additionally, Father challenged the adequacy of the court’s findings regarding the parent-time modification.

Court’s Analysis and Holding

The Court of Appeals affirmed the sole physical custody designation and child support calculation. The court emphasized that under Utah Code section 78B-12-102(15), joint physical custody requires the child to stay with each parent overnight for more than 30% of the year at the time of the order. Because Mother’s increased parent-time was contingent on successfully completing the step-up plan, she was not entitled to overnight stays exceeding 30% when the court entered its order. Therefore, the sole custody worksheet was appropriate.

Practice Implications

This decision clarifies that child support calculations must be based on actual custody arrangements at the time of the order, not theoretical future arrangements. When seeking custody modifications, practitioners should ensure district courts make sufficiently detailed findings explaining their reasoning, particularly with conflicting expert testimony. The court’s reversal on the parent-time issue demonstrates the importance of adequate findings of fact that explain the steps leading to the ultimate conclusion, especially when substantial evidence supports contrary positions.
