Would I be unreasonable to go out and paint my fence. Scenario approx a year ago husband decided to replace all fences on both sides the original posts were wooden and had broken causing our garden to have props holding the right fence up. He went round to the neighbour who was relatively new and advised that he was replacing the fence with concrete gravel boards and posts. She advised that her side of the fence was OK to which my husband responded that if he removed the props that were straddling our garden the fence would fall down and was surprised she didn't know as the old neighbour was aware and advised my husband he would make the new buyer aware (as if he was going to stay he would have gone half's with us) so he agreed times and dates when the fence would be removed to no inconvenience to her or her garden. Fence was removed she then asked if she could have the fence for her wood burner so husband and people that were helping took the old fence round. She then knocked at our door and said that she had too much wood now and could he dispose of the excess which he did. She then paints said fence (we stained our side grey) she painted hers with dark brown stain which has ingressed but not too badly but painted the top of the fence brown when I had stained it grey which can only be seen from the bedroom so I could live with that. Then she hammers things to it only one screw yes screw not nail can be seen so can live with that. We are on the front garden today and notice behind the overgrown bushes which is our next project to tackle she has dark brown stained the section of wood that is the size of a tall gate that connects from our house to her garage and the small fence that is our border in dark brown stain on both sides the small fence being on our land. The section of wood and the fence are on our land so is this trespassing? I am tempted to go out and paint over it even if due to the colour I would have to use garden paint? Opinions appreciated. By the way I hate dark brown stain!
