A registered title holder has real rights over land enforceable against any claimant in the whole world and can seek eviction of any person who occupies, uses or settles on the land without consent. In a summary judgment application in a rei vindicatio action, where the plaintiff produces valid title deeds establishing registered ownership, the plaintiff's claim is prima facie unanswerable. A defendant claiming ownership based on an unregistered agreement of sale, where there are material discrepancies between the land described in that agreement and the land subject to the plaintiff's registered title, and where the defendant fails to explain those discrepancies, does not establish a bona fide defence. If there is an allegation of double sale, the defendant's remedy lies against the seller, not against a subsequent purchaser who has obtained registered title.
