FirstRand Bank Ltd advanced a credit facility of R250 000 to NPGS Protection and Security Services CC for working capital. The sole member of NPGS, Mr Llewellyn Rwaxa, bound himself as surety and co‑principal debtor and secured the indebtedness by registering mortgage bonds over his immovable property, which was alleged to be his primary residence. After NPGS defaulted, FirstRand issued summons for payment of R649 197.39 and sought an order declaring the surety’s immovable property specially executable. The appellants entered an appearance to defend but resisted summary judgment on the basis that no certificate of balance was attached and that the respondent had not adequately explained how the amount claimed was calculated. The High Court granted summary judgment and declared the property specially executable. The appellants appealed to the Supreme Court of Appeal.
