Harvey Hilgendorf was a licensed real estate broker acting as the agent of the Hagues in the sale of eighty acres of farmland. The Hagues, however, terminated Hilgendorf’s agency before the expiration of the listing contract when they encountered financial difficulties and decided to liquidate their entire holdings of land at one time. Hilgendorf brought this action for breach of the listing contract. The Hagues maintain that Hilgendorf’s duty of loyalty required him to give up the listing contract. Are the Hagues correct in their assertion?
