The binding legal principles established are: (1) A purchaser of immovable property who has paid the full purchase price but has not obtained transfer of the property into their name does not acquire real rights (jus in re) in the property and cannot prevent the Deputy Sheriff from attaching the property to satisfy a judgment debt against the registered owner/seller. (2) Under Roman-Dutch law, dominium or jus in re of immovable property can only be conveyed by transfer made before the proper authority (coram lege loci) - i.e., registration. Until such transfer, the purchaser has only a personal right (jus ad rem) against the seller. (3) In interpleader proceedings, a claimant who fails to file a notice of opposition and opposing affidavit as required by Rule 232 is barred under Rule 233(3) from participating in the proceedings. (4) Rule 238(2a) requires that a respondent's heads of argument must be filed within 10 days of being served with the applicant's heads, but if this would fall within 5 days of the hearing date, the heads must be filed at least 5 clear days before the set down date.
