Until the neighbors' attorney gets the Judge's orders written up for signing nothing can be done with the survey or fencing. Those orders will also state who bears the costs for the survey and the fencing (as well as some court costs).
I have a surveyor ready to go. I also will be contacting someone today who I hope will take down the trees along the line so the fence can go up. I don't want DH to even try grubbing out that number of trees. What I don't know right now is whether we will be allowed to do part of the fencing ourselves, the neighbors will be required to do it, or if -- because of the animosity -- the Court will order that an impartial company do the work.
I E-mailed my attorney after the threat was made asking him to do anything he can to get this finished.
