Right or wrong?

My great grandmother passed away last Tuesday night. She and my great grandfather, who passed seven years ago, owned a lot of land. When my great grandfather died, he set up all of his assets in the LLC. Their four children go to meetings and decide what to do with said assets. My dad grew up on that land and has a natural right to fish and hunt on it. Unfortunately, one of his uncles doesn't want to share the land with him. He'll lease it to friends and to my dad, but all of us here think that isn't right. Why should he have to pay for something that he has a right to? None of it makes any sense, but I can promise that we will get to the bottom of this.
