My question involves real estate located in the State of: Maryland, Montgomery County. Neighbor insists that part of our property is theirs, refuses to believe the surveyors marks and has pulled one marker up. They paid to have it resurveyed and since the marker was missing the surveyor used angles to redetermine its location. The new marker was approx 4 feet onto their property. They pulled the marker again. We want to use our property to park a second car but they keep blocking the space off with rocks from our property. We are considering a restraining order but I really doubt this will stop them. We are also putting up a no trespassing sign and will call the cops if they come onto our property but again, don't think this will deter them. Mediation was scheduled but the neighbors cancelled it. There is also a language issue involving an extended family member of the neighbor. Are there any other means/suggestions of resolving this.
