Milton Lawrence Weinbren (Weinbren) was the sole member of Air and Allied Technologies Close Corporation (the CC). On 28 November 2008, he sold a 25% member's interest to Carl Frank Hattingh (Hattingh), who was employed as general manager. Simultaneously, the parties signed a Memorandum of Agreement (MOA), a Members Association Agreement (MAA), and a Buy and Sell Agreement (BSA). The BSA obligated the parties to take out life insurance policies on each other's lives, with the proceeds to fund the purchase of the deceased's member's interest upon death. Hattingh was married to Irma Blackburn in community of property. When she died on 27 August 2012, her half-share in Hattingh's 25% interest fell into her estate, which was bequeathed to her children from a previous marriage. To prevent this, on 29 August 2013, Weinbren and Hattingh signed an Addendum to the MOA (AMA), purportedly cancelling the MOA on the basis that Hattingh had failed to pay the purchase price. The 25% interest was transferred back to Weinbren and registered with the CIPC. Hattingh continued as general manager. Weinbren died on 31 October 2016. Hattingh claimed and received R15,829,833 from the insurance policy he held on Weinbren's life. The executors of Weinbren's estate (the respondents) sued for payment of these proceeds, claiming the BSA was still in force.
