FirstRand Bank Limited (FNB) concluded a written loan agreement for R2.8 million with Gavin Mark Baseley in March 2017, repayable over 180 months and secured by two mortgage bonds over Baseley’s immovable property. Baseley died in October 2017. Ms Lourina Wilson, an heir, was appointed executrix of the deceased estate in December 2017 and admitted FNB’s claim of approximately R3.5 million. In October 2021, an amount of R1,336,044.35 was erroneously deposited into the deceased’s mortgage loan account from attorneys who had handled the sale of Ms Wilson’s personal property. Ms Wilson demanded repayment. Following correspondence, on 30 November 2021 she emailed FNB offering the retained amount as full and final settlement of the estate’s outstanding debt. FNB rejected the offer unequivocally on the same day, but retained the funds and allocated them to reduce the loan. FNB alleged that during a telephone call on 8 December 2021 Ms Wilson agreed the funds could remain; she denied this. On 4 April 2022 FNB issued a notice in terms of s 129(1) of the National Credit Act reflecting a reduced indebtedness of R2,003,415.96, and on 14 June 2022 instituted application proceedings for judgment, interest, and an order declaring the mortgaged property specially executable. FNB’s founding affidavit did not plead compliance with ss 29 and 30 of the Administration of Estates Act 66 of 1965, and it launched an interlocutory application for leave to supplement its papers. The High Court dismissed FNB’s claim, finding that a compromise had been concluded on 30 November 2021 and that FNB’s retention of the funds constituted acceptance despite its express rejection. The Master of the High Court, Cape Town, was cited as the second respondent but did not participate in the appeal.
