Squatter’s rights do not create ownership of the fee; they are only a vehicle toward a prescriptive easement of surface rights. That’s not what adverse possession is about. Because of the tax being paid by the advewrse occupant, the fee is what is under attack.
That’s not a big deal. Down here in Comanche county TX, we have a County Judge who takes possession of elderly senile couples property and sells it for his personal benefit.
Small county and you can’t touch the thief.
There should be a law against this, and there is. But those who enforce the laws also know how to profit from selective/creative enforcement.
