Edward Travis, Donald St. John and others purchased 6,444 acres of land for investment purposes. The amount paid was $33,000. They agreed to share equally the cost of the property, the expense of maintenance, and the profits or losses upon its resale. The property was titled in the name of St. John. It later became necessary to refinance the property, but St. John was the only one able to secure refinancing. He secured $25,000 in personal credit and paid off the original mortgage. The other parties to the investment paid their share of expenses for the next year, but none thereafter. Four years later, St. John wrote to the other parties that the venture was terminated and offered to return their money if he sold the property at a profit. He then sold the property for $100,000. The other parties filed suit against him, alleging that they had a partnership and that he owed them an accounting. Does St. John have to give them an accounting based on their partnership? Explain.
