2. Determination

A. A. The partnership agreement under the Civil Act is a contract under which two or more persons mutually invest to jointly operate a business, and it can be deemed as a partnership agreement only for an agreement to jointly operate a specific business, and the degree of the achievement of a common purpose does not meet the requirements for establishment of a partnership.

(see, e.g., Supreme Court Decision 2010Da51369, Oct. 28, 2010). The following circumstances, i.e., (i) the agreement between the plaintiffs and the defendant on the construction work set forth in No. 1-A-4 through No. 8 is not prepared, and (ii) the plaintiffs and the defendant invested in the company.
