Propfokus 49 (Pty) Ltd (the seller) entered into a written agreement with Wenhandel 4 (Pty) Ltd (the purchaser, a property development company) on 5 July 2004 for the sale of Erf 1410 Kuils River, Western Cape. The original purchase price was R1,000,000 payable on registration plus 2 standard separate title dwelling units or alternatively 3 sectional title units with a combined value of R800,000. The parties later amended clause 2 by deleting the reference to sectional title units, leaving only separate title units as part payment. Propfokus chose two separate title units off plan and concluded purchase agreements for them in October 2004. However, the local authority subsequently zoned the property exclusively for sectional title development. When Wenhandel's attorney notified Propfokus in April 2005 that the units would be sectional title rather than separate title, Propfokus insisted it had never intended to accept sectional title units and purported to cancel the agreement. Wenhandel tendered R1,800,000 cash payment, which was refused. Wenhandel then brought an application for rectification of the agreement and an order for transfer.
