Accordingly, Article 18 of the Act on the Ownership and Management of Aggregate Buildings (hereinafter "the Act on the Ownership and Management of Aggregate Buildings") provides that "the co-owner may exercise his claim against another co-owner with respect to the common area against the special successor," and provides special provisions allowing the special successor of the co-owner to claim against the special successor for the common area regardless of whether he wishes to succeed.

Therefore, a special successor to an aggregate building shall succeed to the part concerning the section for common use among delinquent management expenses of the former occupant.
