The parties married on 25 October 1975 out of community of property and profit and loss by antenuptial contract. The husband was 26, a qualified tool and die maker working as a salesman, and the wife was 20, working as a secretary. They had no assets at marriage. One son, William, was born in 1977. In 1981 the husband started his own abrasives business (Grinding Techniques). Both parties worked extremely hard in building the business. The wife initially did bookkeeping and administration while employed elsewhere, then joined the business full-time in 1985, eventually becoming financial director. The business became exceptionally successful, employing 254 people at trial. The parties accumulated substantial wealth: the husband's estate was valued at R23,710,127 and the wife's at R8,061,319, for a combined total of R31,771,446. Most assets were shares in the family business companies. After approximately 25 happy years, the wife left in 2002 and instituted divorce proceedings, seeking a 50/50 redistribution of assets under s 7(3) of the Divorce Act 70 of 1979. The High Court (Pincus AJ) granted the divorce and ordered the husband to pay the wife R7.8m to achieve equal division. The husband appealed.
