My question involves real estate located in the State of: New York, Schenectady County, City of Schenectady. Me ex wife who is deceased bought a house in Schenectady about 25 years ago. When she purchased it she was told by the owner that 2 few inches of the building next door was on her property. The driveway touches the building. Both her and my daughter maintained the driveway and property. About 5 years ago a new owner bought it. They were friends but after awhile he wanted the relationship to go further and she said no. Than all hell broke loose. Enter the neighbor from hell. She would find nails, broken glass, etc. in the driveway. He got married and the wife joins in on the harassment, etc. Yesterday they had it surveyed. Come to find out in the front of the driveway they own 4' of it. It narrows to about 1.5 foot in the backyard. Now they want to put a fence up the middle of her driveway. Doing this she will not be able to get to her garage as there is is no other way to get there. Can they do this being that my daughter and ex maintained everything for 25 years? The 4 feet is useless to them. They are just doing it out of hatred. Any help would be appreciated. Thank You.
