Can foreign country divorce decrees be registered under Utah's Foreign Judgment Act? Mori v. Mori Explained

The Utah Supreme Court’s decision in Mori v. Mori clarifies an important distinction in how Utah courts handle foreign judgments versus foreign nation judgments, particularly in the context of divorce proceedings.

Background and Facts

Toshiko and Gordon Mori were married in Utah but later moved to Japan, where they divorced through the Tokyo Family Court. After the divorce, Mrs. Mori returned to Utah and filed a complaint seeking to register the Japanese divorce decree under Utah’s Foreign Judgment Act. Mr. Mori challenged jurisdiction, but the trial court denied his objections. The court of appeals found that the complaint failed to state an actionable claim but remanded for further proceedings.

Key Legal Issues

The central issue was whether Utah’s Foreign Judgment Act applies to judgments from foreign countries. The court examined whether the Full Faith and Credit Clause of the U.S. Constitution extends to foreign nation judgments and what remedies are available for enforcing such judgments in Utah courts.

Court’s Analysis and Holding

The Supreme Court confirmed that Utah’s Foreign Judgment Act applies only to judgments “whose acts are entitled to full faith and credit,” which includes only U.S. state and federal court judgments. The Full Faith and Credit Clause does not apply to foreign country judgments. Instead, foreign nation judgments can only be enforced under principles of comity, requiring a separate enforcement action rather than mere registration. Since Mrs. Mori sought only registration without filing an enforcement action, her complaint failed to state an actionable claim.

Practice Implications

This decision establishes that practitioners cannot use Utah’s streamlined Foreign Judgment Act procedures for foreign nation judgments. Instead, they must file separate enforcement actions under comity principles, which involve judicial discretion rather than the ministerial registration process available for domestic judgments. The Court reversed the court of appeals’ remand, ordering outright dismissal since the complaint was fundamentally flawed and amendment would be futile.
