Hi, Can I just take down a fence that my neighbor put up without my agreement? He didn't get a survey, and the placement of the new fence is inside my property I believe, but I don't have a survey. He took down the old fence that was on what seemed to be the property line, (judging by other parts of the fence along the line, driveway edges, line of bushes, and so on), without my knowledge or agreement. If I take the fence down, who do the materials belong to? This is in California.
