2. Determination

A. The parties’ assertion asserts that the Plaintiff is obligated to pay KRW 53,794,49 in the balance of the settlement amount to the Plaintiff, as the Defendant agreed to pay KRW 60,00,000 by preparing the cash custody certificate of this case on September 6, 2010.

In this regard, the defendant prepared a cash custody certificate of this case in the sense that he would pay 60 million won to the plaintiff on the condition that he would be paid 60 million won from D. Since he did not receive 60 million won from D, he did not have the obligation to pay 60 million won to the plaintiff.

B. The evidence mentioned above and the witness F’s testimony as a whole are acknowledged as a whole as follows.
