• Uberrimae Fidei

    Literally, of the utmost good faith. A defining characterization or quality of some (contractual) relationships, of which reinsurance is universally recognized to be. Among other differences from ordinary relationships, the nature of reinsurance transactions is dependent upon a mutual trust and a lively regard for the interests of the other party, even if inimical to one's own. A breach of utmost good faith, especially in regard to full and voluntary disclosure of the elements of risk of loss, is accepted as grounds for any necessary reformation or redress, including rescission.
