Despite this, however, there are certain contracts categories in other industries which are treated differently. Contracts with a seemingly higher duty of disclosure relate to insurance and agency. Such contracts ought to be negotiated in ‘utmost good faith’. When compared to a sale agreement, a contracting party who has specific knowledge that can impact whether the transaction will be concluded or not, has no duty to disclose such information to the other contracting party. As can be seen, the lack of distinct and unambiguous legislative intervention creates uncertainty amongst the parties of a contract regarding whether this duty exists in South African law or not.
