The third and fourth respondents (purchasers) concluded an Offer to Purchase (OTP) with the first respondent (seller) on 4 February 2020 for property in Cape Town at a purchase price of R5,150,000. The sale was subject to a suspensive condition in clause 7.2 requiring approval of a mortgage bond of R4,950,000 by 14 February 2020, with provision for a 30-day extension with written consent. A first addendum extended this to 19 February 2020. The appellant (purchasers' mother-in-law) agreed to provide funds but could not do so by 19 February 2020, causing the OTP to lapse. On 20 February 2020, a second addendum was signed purporting to amend the financing arrangements and extend the deadline to 25 February 2020. The appellant paid R1,950,000 into the conveyancer's trust account. When the purchasers faced financial difficulties due to COVID-19 in May 2020, they sought to cancel. The appellant, having taken cession of the purchasers' claim, sought repayment on the basis that the OTP had lapsed and could not be revived.
