Does a Utah divorce court have to rule on a dissipation claim raised in closing argument? Dahl v. Dahl Explained

Background and facts

Charles and Kim Dahl divorced in 2010 after nearly eighteen years of marriage. The marital home and a Fidelity investment account known as the Marlette account were held in the Dahl Family Irrevocable Trust, which was never joined as a party to the divorce action. Because the Trust was not a party, the divorce court could not distribute its assets, leading to protracted parallel litigation. In Dahl v. Dahl, 2015 UT 79, the Utah Supreme Court held that Ms. Dahl was a settlor of the Trust, that the Trust was revocable, and that she retained an enforceable interest in the marital property it held. The Supreme Court remanded with instructions to identify the marital property in the Trust and distribute it. On remand, the district court valued the Marlette account as of the 2010 divorce decree, awarded Ms. Dahl simple prejudgment interest at 6.73%, credited Dr. Dahl with a $356,201 premarital-asset offset, and never ruled on Ms. Dahl’s claim that Dr. Dahl had dissipated approximately $92,391 in Trust assets. Ms. Dahl appealed.

Key legal issues

The Court of Appeals addressed four issues: (1) whether the district court abused its discretion by using the divorce-decree date rather than the trial date to value the Marlette account; (2) whether awarding simple rather than compound interest was an abuse of discretion; (3) whether the premarital-asset offset was supported by adequate findings on commingling; and (4) whether the court’s repeated failure to address the dissipation claim was reversible error.

Court’s analysis and holding

The court affirmed the 2010 valuation date. Under the general rule, marital assets are valued at the time of the divorce decree, and any deviation requires detailed findings. Here, the district court followed the general rule and provided adequate supporting findings — post-divorce commingling by Dr. Dahl rendered a present-day valuation too speculative. The court also affirmed the award of simple interest, noting that compound interest is disfavored by Utah law and that Ms. Dahl’s own brief characterized compound interest as a substitute for a present-day valuation the court was entitled to reject.

However, the court vacated the Marlette distribution on two grounds. First, the district court’s findings addressed only intentional commingling — whether Dr. Dahl intended his premarital assets to become joint property — but never addressed traceability commingling, the separate doctrine under which separate property loses its character when it becomes inextricably and untraceably intertwined with marital assets. Dr. Dahl himself testified that proceeds from premarital stock sales were “mixed in” with the Marlette account and that tracing might not be possible. Without findings on that question, the $356,201 offset could not stand. Second, despite evidence of apparent dissipation introduced at the evidentiary hearing and a dissipation claim raised in both closing argument and a post-trial motion, the district court never ruled on the claim. Once an apparent dissipation is shown, the burden shifts to the other spouse to explain the expenditure, and a court’s silence on the issue is an abuse of discretion.

Practice implications

Practitioners litigating marital property distribution involving mixed accounts must address both theories of commingling — intent and traceability — in proposed findings and closing arguments. A district court’s failure to rule on a preserved dissipation claim is independently reversible, so ensure the claim appears in closing argument, post-trial motions, and any request for additional findings. Additionally, litigants whose funds are deposited with the court should promptly request deposit into an interest-bearing account under Utah Rule of Judicial Administration 4-301(2); failure to do so waives any claim for interest on those funds.
