Section 742.226 - Mortgagee interest and obligation of mortgageeA fire insurance policy shall contain provisions as follows:
(1) "If loss hereunder is made payable, in whole or in part, to a designated mortgagee not named herein as the insured, such interest in this policy may be canceled by giving to such mortgagee a 10 days' written notice of cancellation."(2) "If the insured fails to render proof of loss such mortgagee, upon notice, shall render proof of loss in the form herein specified within 60 days thereafter and shall be subject to the provisions hereof relating to appraisal and time of payment and of bringing suit. If this company shall claim that no liability existed as to the mortgagor or owner, it shall, to the extent of payment of loss to the mortgagee, be subrogated to all the mortgagee's rights of recovery, but without impairing mortgagee's right to sue; or it may pay off the mortgage debt and require an assignment thereof and of the mortgage. Other provisions relating to the interests and obligations of such mortgagee may be added hereto by agreement in writing."
