2. Determination as to the cause of action

A. On October 15, 2013, the Defendant asserted that the deceased’s heir, including the plaintiffs, and the defendant agreed to pay 1.3 billion won to the above heir after the establishment of the right to collateral security on the instant real estate by inheritance. As such, the Defendant paid 1.5 billion won to F, the deceased’s spouse (i.e., KRW 1.3 billion x 3/25), among the above loans (i.e., KRW 1.3 billion x 25), and 1.4 million to the remaining heirs, who are the deceased’s children (i.e., KRW 1., KRW 1.3 billion x 2/25), the Defendant voluntarily paid 87 billion to F, and 58 million to the remaining inheritors, including the plaintiffs, without any agreement.

Therefore, the amount of custody that the Defendant should pay to F is KRW 69 million (=156 million - KRW 87 million), and the amount of custody that the Defendant should pay to the remaining heirs, including the Plaintiffs, is KRW 46 million (=1.4 million - KRW 58 million).

Thus, the defendant is worth 46 million won each of the plaintiffs' custody funds and 69 million won each.
