Can a party substitute into ongoing litigation by declaring itself the real party in interest? Trapnell v. Legacy Resorts Explained

In Trapnell v. Legacy Resorts, the Utah Supreme Court addressed whether a party could substitute into ongoing litigation simply by filing a notice declaring itself the real party in interest under Rule 17, or whether it must follow Rule 25’s more formal substitution procedures.

Background and Facts

The case involved a dispute over foreclosure proceeds from Zermatt Resort. After the district court entered final judgment against Praia, LLC, Trapnell & Associates purchased Praia’s interest in the litigation. Rather than filing a motion under Rule 25(c), Trapnell filed a Rule 17 notice declaring itself the “real party in interest” and simultaneously filed a notice of appeal. Legacy Resorts and America First Federal Credit Union challenged Trapnell’s ability to appeal, arguing it had never properly become a party to the litigation.

Key Legal Issues

The central issue was whether Trapnell could substitute into ongoing litigation through a Rule 17 notice or whether Rule 25(c) governed transfers of interest during pending litigation. This determination was jurisdictional—if Trapnell was not a proper party, its notice of appeal was invalid, and the appellate courts lacked subject matter jurisdiction.

Court’s Analysis and Holding

The Supreme Court distinguished between Rule 17 and Rule 25(c), explaining that Rule 17 applies when “the interest in a case transfers prior to commencement,” while Rule 25(c) governs “when the interest in a case transfers during the action.” Rule 25(c) requires that substitution be “directed by the court” through a motion process, not through unilateral declaration. The Court rejected the court of appeals’ pragmatic approach, emphasizing that proper procedure cannot be waived even when a party’s intent is clear and the district court acquiesces.

Practice Implications

This decision reinforces the critical importance of following proper substitution procedures in ongoing litigation. Parties acquiring interests during litigation must file Rule 25(c) motions with supporting documentation proving the transfer. The Court’s holding that improper substitution renders appeals jurisdictionally defective means such errors cannot be cured through appellate proceedings—the defect must be addressed at the trial court level before any valid appeal can proceed.
