I am thinking about building a horizontal fence to close the open space left by the previous owner to the left of my garage. How do I join my fence with the exiting fence of my neighbor. Do I have to build my own post next to the one behind the blue garbage bin?
Edit: I am not worried about the legal implications and it does not matter on whose property is the fence. I am just looking for a technical solution
Update: I looked at that post and it was set in concrete and it is rotten as it is the on to the left side on my neighbor's property. There is another one rotten just behind the small tree at the end of the area that I am trying to cover There is no way that I am going to attach my gate to that post unless I decide to replace it and to split the costs with my neighbor. However doing that will complicate the solution. I am planning on using one of these: for the removable central post. I would like to use the same for all the posts but I am not sure if this is advisable. This will be a horizontal fence, made of cedar boards cut of 1x(2" or 3" or 4" or 6")x 8" to match my needs and to build the design that I am planning to use
