Mississippi Code Title 83. Insurance § 83-13-13

In case of destruction or damage of property by fire where the same is insured against fire, it shall be the duty of the insurance company or companies liable for such loss, within a reasonable time after receiving notice thereof, to furnish to the insured proper blanks upon which to make the required proof of such loss, with full directions as to what proof is required to secure the payment of the policy. If the insurance company fails to comply with this section, the failure of the insured to make proper proof of loss prior to the suit shall be no defense to a suit upon the policy, and in all cases the insured shall have a reasonable time in which to make such proof after the blanks and directions are received.
