Dunkin’ Donuts complaint: Taking my driveway Proposed building location of Dunkin

I live next door to a proposed Dunkin Donuts building location which is threatening to have State Highway Adm. close the driveway we have used since 1947. My mother, homeowner is 89 years old and I am trying to assist her with this nasty and strong armed group of people called the Messick Group that are developing the site for Mr. Parag Patel who purchased the location next door to us which I tried to purchase also. They claim the driveway is not documented and that the property line runs down the middle. They claim they need the room to have a handicap ramp and our driveway needs to be moved westward placing us very close to face forward with Queenstown Rd and very difficult to get out. It was all brothers that owned this land at one time so maybe they did not document everything but I have had no luck locating an attorney (called 10 so far) to prove the prescriptive easement which in AACO you only need 20 years of usage.
