EXPLANATION / SCOPE
Under Order 13 rule 42 of the High Court of Lagos (Civil Procedure) Rules, 1972, a sole proprietor carrying on business in a name or style other than their own name may be sued in that business name as if it were a firm. The rule applies once it is established that the person trades under a different name. The business name is treated as the defendant eo nomine. This simplifies litigation against sole proprietorships. The plaintiff need not ascertain the owner’s personal name before suing. The rule prevents concealment and ensures access to justice. The judgment binds the individual behind the business name. The proprietor remains personally liable. The rule applies even without registration of the business name.
