In February 2000 Investec Bank advanced a loan to Erf 436 Elandspoort (Pty) Ltd, secured by a notarial mortgage bond over a long-term lease of commercial property. Erf 436 defaulted in 2002, the lease was cancelled, and Investec’s security became worthless. Investec demanded repayment, causing prescription to commence in September 2002. Thereafter, Investec and Erf 436 concluded agreements under which rental income from sub-tenants and later proceeds from the sale of Investec’s leasehold rights were credited to Erf 436’s loan account. Over several years, rental payments and lump-sum payments were made, and correspondence from Erf 436’s director acknowledged the outstanding indebtedness. In January 2011 Investec issued summons for the remaining balance. The respondents raised a special plea that the claim had prescribed.
