After twenty-nine years of marriage, Robert and Mary Lou Tuttle were divorced. They admitted in court that before they were married, they had signed a prenuptial agreement. They agreed that the agreement had stated that each would keep his or her own property and anything derived from that property. Robert came into the marriage owning farmland while Mary Lou owned no real estate. During the marriage, ten different parcels of land, totaling about six hundred acres, were acquired, and two corporations, Tuttle Grain, Inc., and Tuttle Farms, Inc., were formed. A copy of the prenuptial agreement could not be found. Can the court enforce the agreement without a writing
