Hi there. The Dividing Fencing Act 1991 (NSW) deals with fencing disputes in NSW and regulates neighbours’ responsibilities towards dividing fences. The Act is designed to settle the contentious aspects of sharing a fence. It provides for the way in which shared fencing is to be built and paid for. You mentioned that your neighbour has attached a post to a privacy screen which is on your land. Dividing fences between properties are generally supposed to run along the land boundaries. If your neighbour is placing an object significantly over your land, you should speak with them about where an appropriate place for a dividing fence should be. The Dividing Fences Act encourages neighbours to come to their own agreement about a fence. Because of this, we encourage you to speak with your neighbour. It may be that they are mistaken about the exact placement of the title boundary, in which case you can provide them with information about it.
