Utmost good faith definition

What does Utmost good faith mean?

Utmost good faith, or the principle of uberrima fides, is a term of art for insurance contracts. The common law duty of utmost good faith requires both parties to the contract to disclose all material facts. In practice, the onus of the obligations rests with the party being insured, the proposer, who must disclose all material facts known to it during preliminary negotiations for an insurance contract.

If a proposer fails to make full disclosure, the insurer is entitled to avoid the contract, including if the proposer makes an innocent misrepresentation of a material fact. If the insurer fails to make full disclosure, the proposer’s remedy is the return of the premium and not for breach of contract damages. Case law suggests a proposer/insured may have a claim in damages ‘in an exceptional case’. The common law duty of utmost good faith can be qualified by express contractual terms. These are more common in non-marine insurance contracts, where the amount of disclosure that would otherwise be required can be defined, regulated or limited.
