Article 1844. Sanctions in case of aggravation of risk
(1) If the contract provides that, in the event of an aggravation of the risk insured the insurer shall be entitled to terminate the insurance, such right shall be exercised by written notice to the policyholder within one month of the time when the aggravation becomes known or apparent to the insurer.
(2) Cover shall expire one month after termination or, if the policyholder is in intentional breach of the duty under Article 1843, at the time of receipt of the termination notice.
(3) If an insured event is caused by an aggravated risk, of which the policyholder is or ought to be aware, before cover has expired, no insurance money shall be payable if the insurer would not have insured the aggravated risk at all. If, however, the insurer would have insured the aggravated risk at a higher premium or on different terms, the insurance money shall be payable proportionately or in accordance with such terms.
