Does a spouse's death after bifurcated divorce dissolution eliminate court jurisdiction over property claims? Mower v. Mower Explained

In Mower v. Mower, the Utah Court of Appeals addressed a critical question of jurisdiction in bifurcated divorce proceedings: whether a district court loses authority to resolve property claims when one spouse dies after the marriage has been dissolved but before all issues are resolved.

Background and Facts

Thomas and Lidia Mower stipulated to a bifurcated divorce in 2013, dissolving their marriage while reserving all other issues—including distribution of an estate worth approximately $150 million—for trial. After a contentious 16-day trial spanning from 2017 to 2018, Thomas died in August 2020 before the court could issue its final ruling. The district court concluded it lacked jurisdiction to resolve the remaining property claims and closed the case, directing Lidia to pursue her claims in probate court.

Key Legal Issues

The central issue was whether Thomas’s death deprived the court of jurisdiction over unresolved property distribution claims in a bifurcated divorce where the marriage had already been dissolved. The district court relied heavily on Porenta v. Porenta, which held that divorce actions generally abate upon a spouse’s death because death terminates the personal relationship requiring dissolution.

Court’s Analysis and Holding

The Court of Appeals distinguished this case from Porenta, noting that the mootness rationale underlying abatement did not apply. Since the parties’ marriage was already dissolved years before Thomas’s death—and both had remarried—his death had no legal effect on their marital status. The court emphasized that bifurcation under Rule 42(b) allows divorcing spouses to expeditiously obtain divorce before resolving complex property issues, and that district courts retain equitable jurisdiction over marital property regardless of bifurcation.

Practice Implications

This decision clarifies that courts retain jurisdiction over property claims in bifurcated divorces even after a party’s death, provided the marriage was already dissolved. Practitioners should be prepared to utilize Rule 25 substitution procedures to continue pursuing viable property claims against a deceased party’s estate. The ruling also reinforces that while custody and support claims abate upon death, property distribution claims may survive for estate collection purposes.
