I'm having a problem with our new neighbor
I have lived in our house for 7yrs. Our road/fences were like they are now when we bought the house.. We added nothing to the front of our house. Our neighbors house has been thru 4 other owners in time we have lived here. The road we live on is a private road. The township does NOT take care of it at all.. There are about 10 houses on our road total.. The problem I am having is a little complicated... So please bear with me
Our house is the last house on the road. We "use" the end of the road as a small part of our driveway then our drive turns towards our house in an "L" shape. At the very begining part of our drive is a large cement parking space that starts at the currents road edge and goes towards our house about 15 ft. Our new neighbors current driveway is directly across from our cement parking space. Our road at the end is only about 15 ft wide (its private and VERY narrow and the end of the road).. The problem we are having is that she is upset that I have to use her driveway to back up my car into our parking space. There is a tree in the way of my backing my truck (suburban) if I was to pull in frontways anyways.. not to mention our road is so narrow that I have to use a small part (maybe 10 ft) of her drive(which is over 150'long) is be able to pull in my big truck..She came over here on Christmas Eve night and threated her 4 brothers on us if we pulled into her driveway again.. So I called the townships sherriffs dept. and they said by-law that I or anyone can pull into a driveway as a right of way and that she couldnt put a fence up(at the border of her property and the road) or anything to keep that from happening.. So now she is upset about that.. So she called in the land surveyors. They are here today and have put stakes in where her property corners are at.
The PROBLEM is that her pro. line is actually about 5 ft into where the road is and has been for over 40 yrs. I have a fence where my drive starts (past the cement parking area) and she has a fence there bordering her property (even though her fence is in her pro. about 10 ft.)( So just to clarify.. her fence is 10 feet into her property then my driveway which is about 10 ft wide then my fence...) SO.... Technically I cant drive onto my property w/o driving thru hers first with how the road is set up... She told me previously that she didnt care how the road was that I had to rip down my fence if I wanted access to my drive/garage. BTW back in the 80s all the current land owners decided to move the road about 10 ft her way to get the road away from our side so it wasnt so close to the houses on this side.

SO..... My ???s are...
Since the road, fences and supposed property has already been set up this way for at least the last 20 yrs... is that "grandfathered" in?
Do we have to move our fence, road?
What are the laws and where could I go to find out?
I went to the township once before and they just had a map to show is... they wouldnt come out since its a private road.
Please HELP before theres WWIII on our small county road!!!!!
Thanks in advance!!!! Much appreciated!!!
