Intercontinental Exports (Pty) Ltd instituted action against F T Fowles to rectify a written deed of suretyship and to recover R2 178 844,43 owed by Security Depot (Pty) Ltd for goods supplied. The suretyship, adapted from a banking form, incorrectly described Mr Frank Fowles as the principal debtor and included a clause referring to banking facilities, although the true intention was that Fowles would stand as surety and co‑principal debtor for the company’s indebtedness. The errors were alleged to be due to a common mistake. The appellant sought rectification of the suretyship, payment of the debt, interest, and attorney‑and‑client costs. Default judgment was refused in the court a quo on the basis that the suretyship was formally invalid. The appellant appealed to the Supreme Court of Appeal.
