An apartment building housing 3 families caught on fire next door to a house that I own and collapsed and burned to the ground. According to the final fire report, the cause of the fire cannot be determined. There was extensive damage to my house, and it is considered a total loss. The owner of the apartment building did not have insurance, nor did the tenants. I also did not have insurance. Since the cause cannot be determined, do I have any case legally concerning damage to my property? Thanks.
