RE: I need Legal advise
I wonder if you could claim that the old county road acted as an ‘access easement’ and that you still have the rights to use it (that’s a question for a lawyer) and therefore your rights to the old road should be ‘grandfathered in (AKA - you still have rights to that old road bed as a legal easement)? As mentioned by others it sounds like you need a good lawyer that isn’t in the good ole boy network….
Good luck!
