Larry and Nancy Von Behren (plaintiffs) owned a three-fourths interest in a 170-acre tract of land. Shirley Oberg owned the other one-fourth interest. The tract was hilly and a river flowed through the property, effectively severing a field at the bottom of the tract. The Von Behrens filed a petition for partition of the property. An expert witness hired by Oberg testified that the tract was actually worth less as a whole than if broken up into smaller tracts. The trial court ordered partition in kind, awarding Oberg 50 acres and the Von Behrens 120 acres. The Von Behrens appealed.
