2. Summary of the parties' arguments

A. The plaintiffs E did not sell the land of this case before birth, and the plaintiffs, the inheritor, did not sell the land of this case.

Moreover, E had already died on May 3, 1970, and F had the ownership transfer registration on the instant land due to sale on February 5, 1971.

Therefore, the registration of transfer of ownership in F’s name on the land of this case is the registration of invalidation of cause, and the registration of transfer of ownership in the name of the defendant based on this is also null and void.

Therefore, the defendant is obligated to implement the registration procedure for transfer of ownership for the restoration of real name in relation to the share of 2/5 of the land in this case and the share of 3/5 to the plaintiff B.

B. Defendant F purchased the instant land from Plaintiff A.

Since F and the defendant, as his bereaved family members, occupy the land of this case as the intention to own it for about 40 years, the acquisition by prescription was completed.

Since the ownership transfer registration under the name of the defendant with respect to the land of this case is valid registration consistent with the substantive legal relationship, the plaintiffs cannot comply with the plaintiffs' request
