We have neighbors here in town that when this house was bought by my parents they were forced to sign an easement at the time of purchase. Come to find out when the land was surveyed their drive way was on our property.. as well as their garage. The easement was only to give them the right to use a small 6 inch portion of our yard to get to their garage.
When I bought my parents house I refused to sign said easement and guess what.. the City stepped in and they had to move their garage 11 inches.. as well as remove part of their driveway and re-sod the yard.
