(2) According to the reasoning of the lower judgment, the lower court erred by misapprehending the legal doctrine on the premise that the Plaintiff’s lease agreement was terminated on October 14, 2014, and that the Plaintiff transferred the instant house to the Defendants, and thus, did not err by misapprehending the legal doctrine on the premise that the Plaintiff’s lease agreement was completely terminated on or around December 8, 1998, and that the Plaintiff transferred the instant house to the Defendants. As such, the Defendants, a joint lessor, jointly with the Plaintiff, jointly leased KRW 50,00,000,000, and Defendant B’s delivery of the copy of the instant complaint to the said Defendant.
