The respondent was executrix of her deceased husband's estate. The deceased owed debts on two overdrawn current accounts at Trust Bank (whose successor was the appellant ABSA Bank), secured by mortgage bonds over landed property. A life insurance policy ceded to the bank as security had lapsed due to non-payment of premiums, which the respondent blamed on the bank. The respondent's attorney sent a cheque for R180,000 under cover letter dated 16 July 1997, stating it was offered "in full and final settlement" of both accounts, though the total indebtedness was approximately R370,000-R380,000. The bank deposited the cheque on 8 August 1997, appropriated the proceeds to the larger overdraft account, and wrote a letter dated 8 August 1997 disclaiming acceptance of the payment as full settlement. The bank then sued for the balance, and the respondent raised settlement as a defense.
