What is the name of your state? Oregon. We live in a 3 year old subdivision. Our neighbors back yard backs up to our side/front yard. Our neighbors built a fence directly on the property line, separating our side/front yard from their back yard. Now they want to paint the fence that is facing in our property area, which would extend from the front of our property line, all the way to our back gate. The fence is only 5 feet from our house. Do they own the entire fence; both sides? Do they have the right to come on to our property and paint the fence...becasue it is exactly on the property line. In these newer subdivions, it's entirely common for one household to only end up building 1/2 of the fence, as adjacent homes may have already built part of the fence on the property line. So, should I only be staining/painting 1/2 of my fence since that's all I paid for?
