Mrs Brenda Benjamin Burger was married in community of property to Victor Burger since 13 July 1963. On 17 March 1992, the High Court (TPA) declared Victor Burger mentally disturbed and incapable of managing his own affairs due to injuries sustained in a motor accident. Mrs Burger was appointed as curator to his person and estate with specified powers set out in an annexure to the court order. On 7 December 1994, Mrs Burger signed a document in which she ceded a fixed deposit of R500,000 at Saambou Bank to the appellant and bound herself as surety and co-principal debtor to the appellant for R500,000 in respect of a mining contract between the appellant and Michette Mining Services (Pty) Ltd. The document was attested by two witnesses. When the principal debtor failed to fulfill its obligations, the appellant claimed payment of R500,000 from Mrs Burger based on both the cession and the suretyship. Mrs Burger defended the claim primarily on the ground that the cession and suretyship were not valid and binding against her. At the time the court order appointing her as curator was made, the provisions of sections 14, 15 and 16 of the Matrimonial Property Act 88 of 1984 did not apply to marriages concluded before the Act came into force. However, before Mrs Burger signed the undertaking, section 11 of the Act was amended and these sections became applicable to all marriages in community of property regardless of when they were concluded.
