Property line dispute

[Handel Carter]

I got a letter from a lawyer that part of my driveway is on his clients property. When I purchase the home, the driveway was paved. Has been for 30yrs I’m told. The letter says my options are return to prior state, which to me is nothing but what I see, pay lump sum to purchase or lease it. Is this on the real estate company that sold me this? I’m not paying for something I didn’t do, nor just going to lay down to losing part of a driveway that was sold to me. Any thoughts?
