The person who held the land filed bankruptcy then sold the property before giving me anything including that he was going to sell.
If someone else other than your mother held title to the property, you don’t have anything to inherit. Assuming there was a legal basis for your claim to the property, you probably should have intervened in the bankruptcy. If you weren’t listed as a creditor, you can possibly still maintain an action again the person who defrauded you. Speak with a local attorney who can review all your options and help you decide how to proceed.
