Fraudulent concealment justifying a rescission of a contract is the intentional concealment of some fact known to the party charged, which is material for the party injured to know to prevent being defrauded; the concealment of a fact which one is bound to disclose being the equivalent of an indirect representation that such fact does not exist.
