The appellants were trustees of the Century City Property Investment Trust, a commercial trading trust with 23 beneficiaries. The respondent, Ms Deans, was the ex-wife of one trustee (Mr Deans) and had been a beneficiary during her marriage until divorce on 8 February 2019. Following property sales in 2013-2014, the Trust earned substantial capital gains. During the 2014 and 2015 tax years, trustees allocated net income from capital gains totaling R184,179,657 to beneficiaries, including R6,329,939 to Ms Deans. These amounts were reflected as vested liabilities in the Trust's 2017 Annual Financial Statements. In July 2021, Ms Deans sued for payment of R6,329,939. After the Trust filed a plea, Ms Deans applied for summary judgment. Critically, Ms Deans' particulars of claim were based on an amended trust deed dated 11 May 2015, but the allocations had actually occurred in 2013-2014, before this amendment. The original trust deed dated 13 June 2006 was therefore applicable. This error only became apparent at the summary judgment hearing. The trustees admitted the allocations but relied on clause 15.2 of the original trust deed (or clause 5.6 of the amended deed as pleaded) to justify withholding payment until a vesting date or Ms Deans' death.
