Home Burnt Down & Loss of Most Property

My home recently burnt down and we lost most of our things. There have been many issues and problems concerning what started the fire and they're trying to blame us and charge us for the damages but we know for certain its not our fault. They are no longer letting us enter the premises so we have been living off the clothes on our backs. Its been a real struggle trying to find a place to live. Its only me and my mom and we need help raising money for a lawyer to help us fight, to get our rights and property back. I have a very limited amount of time and whatever is given will help tremendously. Thank you
