I bought a foreclosed home built in 2007 about 3 years ago in King County, WA. The builder encroached on the neighbor's empty lot by building a hedge and a small portion of the driveway. I tried to settle the encroachment by offering to buy the area of encroachment after reviewing the official survey done by the neighbor. He wanted $11,500 for an area of about 300 sq ft. I did not agree to this. He threatened to remove the encroachment and sue me for the cost of removing the encroachment. I did not intentionally built these structures to encroach on his property. Can I be sued for this? thanks so much for your input.
