1. All appeals filed by the Defendant (including the Plaintiff) are dismissed.

2. The costs of appeal are assessed against the Defendant (including the Plaintiff).

1. The reasoning for the court's explanation on this case is that the court of first instance, as additional evidence submitted by the court of first instance, rejected the entries in the evidence No. 6 or No. 8 (including the provisional number) sufficient to recognize the Defendants' assertion that Defendant C leased the instant real estate from the Deceased, and except where the court of first instance dismissed the "non-joint and several relationship" of No. 4 and the "non-joint and several relationship" of No. 4 of the judgment of the court of first instance as "non-joint and several obligation relationship", and therefore, it is identical to the judgment of the court of first instance. Thus, it is acceptable

2. In conclusion, the plaintiffs' claims against the plaintiff are justified, and the defendant C's counterclaim claim is dismissed as without merit. The judgment of the court of first instance is just in conclusion, and the defendants' appeal is dismissed as it is without merit. It is so decided as per Disposition.
