An old, blind lady who befriended me because I was extremely patient with her and refused to take advantage of her during the leasing process had an issue that she was dealing with on a separate tract. Her father had sold some land to the State of Texas in the 1960's for construction of the Interstate highway going through his property, and reserved all minerals. Then he sold the land on each side, kept the minerals on those adjoining tracts, but because he did not make it undeniably clear when he sold the tracts on either side of the highway that he intended to keep the minerals UNDERNEATH the highway, an appellate court in Texas whose jurisdiction covers several counties in the Barnett Shale said that, under the strips-and-gores doctrine (not a state law but a doctrine in case law), those minerals now belong to the landowners on either side of the highway, split evenly. As I recall, this court case, whose styling I cannot recall, said that the Court Order applied retroactively, which seems like an unbelievable miscarriage of justice. After all, people in these types of situations might have been going on for decades or generations thinking that they owned these minerals and then, just because one man in a robe says so, they don't? It seems like those scenarios that happened before the court case should have been "grandfathered." Anyway, I don't think it's worth hiring an attorney because I think the Title Opinion in your case is correct.
