If the insurer denies a claim, the denial will not apply to the mortgagee if the mortgagee has notified the insurer of any change in ownership or occupancy, pays any premiums due, and submits a signed proof of loss within 60 days. In addition, if the insurer decides to cancel or nonrenew coverage, it will provide the mortgage holder with 10 days advance written notice. Nothing the insured does can impair the rights of the mortgagee.
