Uberrima fides (sometimes seen in its
genitive form uberrimae fidei) is a
Latin phrase meaning "
utmost good faith" (literally, "most abundant faith"). It is the name of a legal doctrine which governs
insurance contracts. This means that all parties to an insurance contract must deal in good faith, making a full declaration of all
material facts in the insurance proposal. This contrasts with the legal doctrine
caveat emptor (let the buyer beware).
