1. The plaintiff's claim is dismissed.

2. The costs of lawsuit shall be borne by the Plaintiff.

1. The Plaintiff’s assertion is the owner of multi-household 102 located in Jeju-si, and the Defendant is the owner of the above multi-household 202. The Defendant did not repair water defects on the floor of the above 202, thereby occurring in the ceiling of the above 102, which is owned by the Plaintiff.

The plaintiff has caused damages to the lessee for the amount of KRW 1.5 million, and caused damages to the lessee for the amount of KRW 2,000,000,000,000 for the cost of waterproof construction.

2. The evidence presented by the Plaintiff alone is insufficient to acknowledge that the water leakage phenomenon under the above 102 was caused by the defect in the construction or preservation of the Defendant’s exclusive ownership, and there is no evidence to find out the cause of water leakage otherwise.

(The plaintiff did not apply for appraisal of the reason for water leakage). Therefore, it is difficult to accept the plaintiff's assertion.

3. As such, the plaintiff's claim is dismissed on the ground that it is reasonable.
