2. Determination

A. The plaintiff's assertion that the plaintiff purchased the land of this case from E on July 2, 1997 at KRW 20 million, and paid the above purchase price in full and cultivated and occupied the land of this case until now. As such, the defendant C, the inheritor of E, is obligated to implement the procedure for the registration of ownership transfer of the land of this case to the plaintiff.

Since the sales contract for the instant land between Defendant C and Defendant B is null and void as an anti-social legal act that the Defendants concluded in collusion, Defendant B is obligated to implement the procedure for the cancellation of ownership transfer registration for the instant land.

B. In full view of the statements in the evidence No. 12 and No. 3, and the witness J’s testimony on July 2, 1997, E sold the instant land to the Plaintiff et al. and three other parties as the intermediary of J on July 2, 1997, and the contract deposit amount of KRW 5 million was paid at the time of the contract, the intermediate payment of KRW 5 million, and the remainder payment of KRW 10 million was paid on July 20, 1997, and before the remainder payment was made.
