1. In case where the existing building is destroyed and the new building is built, even if there is a mutual similar surface in materials, location, structure, and other sides of the building, the newly constructed building cannot be deemed to be the same building as the one where the new building has been destroyed and then its registration cannot be deemed to be valid as a registration for the new building; and

(see, e.g., Supreme Court Order 2012Ma1235, Oct. 29, 2012). Therefore, the establishment registration of a neighboring mortgage on the old building cannot be deemed valid on the ground that the establishment registration of a neighboring mortgage on the old building was conducted on the registry of the previous building with intent to establish a collateral security on the old building.

(see, e.g., Supreme Court Decision 91Da39184, Mar. 31, 1992). Also, as one of the requirements for establishing legal superficies under Article 366 of the Civil Act, the existence of a building at the time of the establishment of a mortgage is required. In such cases, if the building has the elements as a building, it is necessary to complete the registration.
