C. On September 11, 2007, with respect to the shares of M and H among the instant building and the instant land, the registration of ownership transfer was completed on September 5, 2007 due to a compulsory auction under Defendant B’s name.

After that, each share of N andO among the instant land was sold to Defendant B, J, and K respectively to Defendant B, and L’s share was sold to P as a compulsory auction, and the auction procedure was conducted for partition of co-owned property according to the conciliation formed in the lawsuit brought by P, and the Plaintiff acquired the ownership of the instant land on June 9, 2014.

【Ground for recognition】 The fact that there has been no dispute, Gap's evidence 1-1 and 2, the purport of the whole pleading

2. The assertion and judgment

A. If the Plaintiff’s assertion that Defendant B obtained statutory superficies under customary law, it would be unfair that one of co-owners of land would allow the disposal act to the share of another co-owner. Therefore, Defendant B cannot be deemed to have acquired the statutory superficies under customary law for the ownership of the instant building with respect to the instant land.

Therefore, Defendant B is obligated to remove the instant building, deliver the instant land, and return unjust enrichment equivalent to the rent from June 10, 2014 to the date of the completion of delivery, which is the following day after the Plaintiff acquired ownership. The rest of the Defendants is the possession of the purport of the claim.
