Can beneficiaries recover prejudgment interest when the conversion date is unknown? Fisher v. Fisher Explained

In Fisher v. Fisher, the Utah Court of Appeals addressed whether trust beneficiaries could recover prejudgment interest on conversion damages when the timing of the conversion could not be established. The case arose from a family trust dispute involving allegations that a trustee had converted fifty head of cattle.

Background and Facts

George and LaRue Fisher created a family trust in 1975. Their son Brent managed the family ranch and conducted cattle operations on the property. After George’s death in 1992, Brent became co-trustee with LaRue. In 1995, the co-trustees executed an allocation listing fifty head of cattle as trust property valued at $42,000. Brent’s siblings later sued him for conversion of trust cattle and unpaid rent for use of the ranch. The trial court found that Brent had converted fifty head of cattle valued at $550 each and awarded prejudgment interest to the plaintiffs.

Key Legal Issues

The primary issue on appeal was whether prejudgment interest was properly awarded when the exact date of conversion could not be determined. Utah law requires that for prejudgment interest to be recoverable, “the damage is complete, the amount of the loss is fixed as of a particular time, and the loss is measurable by facts and figures.”

Court’s Analysis and Holding

The Court of Appeals reversed the prejudgment interest award regarding the cattle conversion. The court noted that the trial court itself admitted “the date [o]n which [Respondent] converted the cows is unknown.” This failure to establish a specific conversion date meant the loss was not “fixed as of a particular time” as required by Saleh v. Farmers Insurance Exchange. Additionally, the court found the loss was not sufficiently measurable by facts and figures, noting the trial court’s “frustration with the fact that there was no direct evidence as to valuation in 1995.”

Practice Implications

This decision emphasizes the strict requirements for prejudgment interest awards in conversion cases. Practitioners must ensure they can establish both the specific timing of conversion and present sufficient evidence for precise damage calculations. While evidence may be adequate to support a damages award under the clearly erroneous standard for factual findings, it may still fall short of the certainty required for prejudgment interest. The case also illustrates that courts will distinguish between what evidence is sufficient for liability versus what is necessary for prejudgment interest calculations.
