2. The parties' assertion

A. The plaintiffs' assertion No. 701 of the apartment of this case, plaintiff Eul's 705 of the apartment of this case, plaintiff Eul's 706 of the apartment of this case, and plaintiff Eul's 706 of the apartment of this case from the defendant association, respectively. The buyers who purchased the apartment of this case on September 7, 2010, and the above three households which the plaintiffs purchased are part of the 14 households that F decided to manage and use the sales price under the execution contract with the defendant association. The plaintiffs paid in full the F.

However, the apartment of this case was sold to a third party after the commencement of voluntary auction procedure, and thus the defendant union is unable to perform its duty to register the transfer of ownership to the plaintiff A. Thus, the defendant union is the plaintiff A.
