On May 27, 2016, C representing the Defendant as the child of the Defendant (seller) concluded a sales contract with the Plaintiff (Buyer) with respect to the building D, E, and both land and both land (hereinafter “instant real estate”) owned by the Defendant (hereinafter “instant contract”) on the following terms:

If the seller has entered into a contract, he/she shall compensate for the amount of the down payment, and if the buyer has entered into the contract, he/she shall not claim the return of the down payment.

B. By June 2, 2016, the Plaintiff paid the down payment of KRW 91 million to C.

2. The parties' assertion

A. On July 19, 2016, the day before the date of the first intermediate payment payment ( July 20, 2016), the Plaintiff asked C to postpone the date of the intermediate payment, and C had extended the date of the second intermediate payment on August 3, 2016.

However, on August 1, 2016, before the late payment date of intermediate payment, C unilaterally reversed the contract by phone call to the Plaintiff and became the middle contract payment.

Therefore, the Plaintiff was released from the instant contract on the grounds of the Defendant’s nonperformance, and the Defendant is obliged to pay the Plaintiff KRW 182 million, a double of the down payment.

B. Defendant C, like the Plaintiff’s assertion, did not extend the payment date of the first and second intermediate payment to August 3, 2016.

However, on July 21, 2016, after the date of the first intermediate payment payment, C extended the payment of the plaintiff to the second intermediate payment by August 1, 2016, which is the date of the second intermediate payment payment.

Nevertheless, the Plaintiff paid the first and second intermediate payments by August 1, 2016.
