NBS Bank Limited (predecessor of BOE Bank Limited, the appellant) extended credit to Zandills Shoe Manufacturers Limited (the Company) pursuant to two action bond agreements secured by two mortgage bonds over immovable property owned by the Company. On 3 July 1996, the respondent bound himself in writing as surety and co-principal debtor for the Company's debts, renouncing the benefits of excussion and division. The Company was finally wound up on 12 May 2000. On 26 October 2000, the appellant proved a claim against the Company of R1,972,721.06 plus interest and stated in its affidavit in terms of s 89(2) of the Insolvency Act that it relied solely on the realization of its security (valued at R800,000). Liquidators were authorized to abandon the secured assets to the appellant, and on 14 November 2000, they concluded a Deed of Abandonment with the appellant for R800,000. The appellant then sued the respondent as surety for the shortfall of R623,891.13 and R385,897.40 plus interest. The High Court dismissed the claim, finding that the appellant's election to rely solely on its security extinguished the balance of the claim and released the surety.
