Hi, I am selling my house where I have lived for 18 years. I own the driveway, but allow our neighbors to use it as their driveway as well to get to their garage. There is no written easement. They have lived there about 4 years. We have someone interested in buying our house but they want our neighbor to sign a paper saying they don't own the driveway, and they are OK with 6 months notice if our buyer wants to fence it in. My question is -can the neighbors claim squatters rights to our driveway? And prevent the new buyer from fencing it? Thank you for any help you can give me.
