State of Rhode Island
Easement/or Right of Way

I purchased my property less than 7 years ago. He was there before me. My neighbor and I currently share a driveway which I own and no easement has been granted. The houses were built 30+ years ago. I wish to seperate our 2 properties with a fence which would effectively not give him access to his parking spots. Do I have a right to do this? He could put in his own driveway as he is not landlocked, but again currently uses mine? How do I approach doing this?
