Date of decision:
(undivided one-half interest in 15,000-acre cattle ranch owned in trust, but trustees (children of decedent) ran ranch as though trust did not exist; trustees engaged in self-dealing by leasing trust ground to themselves and breached fiduciary duty by not leasing trust ground to surviving spouse (mother of the trustees) at higher rental rate; no contract existed between mother and son for mother to make a will leaving son her portion of ranch in return for his ranching services; son lacked standing to sue mother for quantum meruit compensation for working and managing ranch and for expenses incurred).
