(1) In the case of building fire insurance, the insurer must disclose, in writing and without undue delay, to a mortgage creditor who has declared his or her mortgage in the event that the single or first premium is not paid in good time, or the policyholder is given a deadline by when he or she must pay a subsequent premium. This also applies if the insurance agreement is terminated once the deadline expires on account of the non-payment of the subsequent premium.
(2) The insurer informs a mortgage creditor who has declared his or her mortgage in writing of the occurrence of the insured event within one week after he or she has learned thereof, unless the loss or damage is immaterial.
