That's not always the case. Property acquired via tax sale is free of easements. We had a case here in Idaho that worked it's way through the courts where a landowner became landlocked after the neighbor bought a property via tax sale.
Not sure that is for all states.
I think this guy needs an attorney however with what this person is trying to do on the easement.
Yes as I told him he simply needs to call either the closing attorney who closed the sale or the title company who issued title and they will tell him what the legality is and be glad to inform his neighbor as well. This is very common not complicated stuff. There is zero need to spend money dragging a new attorney into this. Ingress/egress easements are clearly spelled out in the title papers and/or warranty deed and run with the property.
