<prompt> Human: Apparently my great great grandfather owned lots of land in Texas and set up a trust to keep the land in the family. My father never knew he was entitled to any land until about 10 years ago, he received a letter from lawyers asking if we would allow a certain mining company to harvest the crude and or natural gas. My father never replied and so as far as we know, the land is not being mined. My father is in his 70s and just doesnt know where to begin with his inheritence. My questions are...1. What steps does my father need to take to begin putting this land to work?2. Who might we contact to learn more about this land and the details concerning his inheritance?3. If the land has been used without our consent, could we in fact file a lawsuit against any such company?  <response>: Sounds like he needs to contact that lawyer if you dont even know where the land is. You need to find out how the trust is set up, whos been paying taxes, who else is a stakeholder in it etc. It may be that your father is not the only stakeholder and the lawyers are managing the land as a trust for multiple entities. You wont know until you contact the lawyer and find out what is going on with the property.
