Dillon and Alexei owned a 20-hectare parcel of farmland as tenants-in-common.For many years they operated a vegetable growing operation, each farming and harvesting a 10-hectare part of the the parcel. Each made his own decisions as to crops planted and harvested.They share equally the cost of property taxes, the only expense related to their ownership of the land.Each kept the profits earned from their respective farming operations, but Alexei usually earned double the profits of Dillon because he specialized in growing unusual and high-value vegetables.Just before one harvest season, Alexei was killed in a traffic accident.To save the crop, his widow and only heir-at-law, helped Dillon harvest both of the 10-hectare crops. When the crops were sold, Alexei's widow asked Dillon for the proceeds from the sale of the crop from Alexei's 10-hectare parcel. Dillon offered her half of the net proceeds from the total 20 hectares after the deduction of his production expenses.

Discuss the rights of the parties. How would a court likely decide the issue?
