An error as to the age of the insured only renders the insurance null and void if the insured’s true age is outside the limits set for the conclusion of contracts by the insurer’s rates.
In any other case, if, as a result of such an error, the premium paid is lower than that which should have been paid, the capital or annuity guaranteed is reduced in proportion to the premium received and that which would have corresponded to the insured’s true age. If, on the other hand, as a result of an error in the insured’s age, too high a premium has been paid, the insurer is obliged to refund the excess premium without interest.
