2. Determination as to the Plaintiff’s claim for the refund of KRW 600 million deposit and delay damages against Defendant C, D, E, F, G, and H (hereinafter “Defendant C”)

A. 1) In the event that a lessor died before the termination of a lease agreement, co-inheritors jointly succeed to the status of a lessor under the lease agreement. In such a case, it is reasonable to view that the same legal relationship as the case where several co-inheritors exist. As such, the obligation to return the lease deposit constitutes an indivisible obligation in its nature (see Supreme Court Decision 98Da43137, Dec. 8, 1998 with respect to an indivisible obligation of a joint lessor). According to the foregoing recognition, the Plaintiff paid KRW 600 million to the Deceased upon the lease agreement of this case. After the death of the Deceased on March 26, 2015, the Defendant C et al., his heir succeeded to the status of the joint lessor under the lease agreement of this case, and thereafter the lease of this case was terminated on March 8, 2017, barring any special circumstance.
