A. The Plaintiff’s assertion against D on September 23, 2016, acquired the amount of KRW 215,752,000 as the preserved claim against D following the revocation of the fraudulent act.

However, on December 3, 2014, under the process of a lawsuit seeking revocation of the said fraudulent act, D entered into the instant mortgage agreement with Defendant C with the maximum debt amount of KRW 58,500,00 with respect to the instant real estate, and completed the establishment of a mortgage on the following day, and entered into the instant property division agreement with Defendant B on March 23, 2015. The instant mortgage agreement and the instant property division agreement constitute a fraudulent act.

As to the cancellation of the instant mortgage agreement and the instant property division agreement, the amount of the secured claim and the instant property division agreement shall be revoked within the scope of KRW 100,00,000, which is the lesser amount between the secured claim and the joint security value, and the Defendant C shall be entitled to the cancellation of the said establishment registration and the Defendant B shall be entitled to compensation for the equivalent amount of KRW 100,00,000,000, which is the lesser

However, at the time of such fraudulent act, there has already been a legal relationship that serves as the basis for the establishment of the claim, and the claim should be established in the near future by based on such legal relationship.
