I have a problem that requires a legal opinion, my next door neighbor in my absent moved the propety line to acomodate her desire after being told that it was not for sale. The five foot fence is all on my property. Do I have any obligation to let this land grabber get away with it. What can happen if I tear this fence down and claim my right of ownership. It is in one of the most expensive area of Santiago due to an unpoiled neighborhood.
