2. Determination

A. As long as the collection order of this case was revoked for the foregoing reasons, the defendant's money between the collection execution year was lost by unjust enrichment, and thus, the defendant is obliged to return it to the plaintiff.

B. The defendant asserts that regardless of whether the collection order has been revoked, the defendant is a legitimate creditor, and thus, the defendant does not have a duty to return unjust enrichment.

However, even if the final judgment of this case, which is the claim against the deceased or its executive title, is rendered, the plaintiff, who is the inheritor who made the qualified acceptance, is not inherited property.
