My neighbor built a shed on part of my property in 1998. We had a verbal agreement that I was aware of this. He sold his house last month and asked me to sign a quick claim deed for the new owners. I was under the impression that it was a very small piece of property, just 11 feet. I started asking questions and found the surveyor had added more of my property than I even knew about or agreed to. Almost 7000 feet to be exact. My neighbor had apparently shown the surveyor exactly where he wanted the pins and line to go to inculde his driveway, which he also put on my land. Are there any steps I can take now or do I just chalk this up to being dumb and trusting?
