Bondev Midrand, a property developer, sold residential properties in Midstream Estate to the respondents with conditions registered against the title deeds. The conditions required purchasers to erect dwellings within 18 months, failing which Bondev would be entitled (but not obliged) to claim re-transfer of the property against repayment of the original purchase price. Transfer to Ramokgopa occurred in November 2006, with the 18-month period expiring in May 2008. Transfer to the Pulings occurred in March 2000, with their building period expiring in September 2008. Neither party built a dwelling within the prescribed period. Bondev instituted proceedings in January 2014 (Ramokgopa case) and March 2014 (Puling case), seeking orders for re-transfer of the properties. The respondents raised prescription as a defence, arguing that the debt had become due when they failed to comply with the building obligation and had prescribed three years later. The Gauteng Division, Pretoria dismissed both applications on the basis of prescription.
