Check with the insuror. You probably have a separate right to claim for the fire loss, to the extent that you're damaged by the loss of the house. If you are successful in pursuing your claim with the insuror, they will bear the burden of recovering from the insured.
There is a three year limit on endorsement claims on checks (most states).
