The Plaintiff’s assertion 1) Plaintiff A’s assertion that the first transfer registration of ownership transfer is false as it was completed by the instant sales contract, which is the most trade concluded between Plaintiff A and E, in order to avoid the obligation to refund the deposit to the lessees residing in the instant real estate. As the Defendants, E’ children, are aware of such circumstances and completed the registration of ownership transfer in sequence 2 and 3, the registration of ownership transfer is eventually called “each of the instant ownership transfer registration”.
