Shared Boundary Fence: Who Pays and How to Sort It

Neighbours generally split the cost of a plain, sufficient fence. In WA, the Dividing Fences Act 1961 has neighbours share the cost of a sufficient fence equally, and an owner who wants more than a sufficient fence pays the difference. The Act and its guidance set out the detail for your block.

An even split is still a fair starting point for the talk. The sticking point is usually what counts as enough. A basic Colorbond or timber fence is one thing. Taller panels, a decorative top or a glass section is an upgrade, and the person who wants it normally covers that part.

A written quote makes this easier. Two neighbours arguing over a guess will stay stuck. Two neighbours looking at a measured price can see exactly what each side is paying for.

Start with the problem you can both see: the lean, the gap, the cracked sheets. Most people accept a fence is failing once they are standing next to it.

Have a rough idea of the fence you want before you knock. A neighbour is more likely to agree to something specific, like replacing the rotten section with matching panels, than to a vague plan.

If the talk stalls, a measured quote gives you both something concrete. Land disputes over fencing often come down to cost and style, and a written price takes some heat out of both. Keep the conversation friendly and in person where you can, since a letter can read as a demand.

Repair when the damage is limited. A few rotted posts, a leaning section or sheets knocked out by a storm can often be fixed on their own, which keeps each owner's share low.

Replace when the whole run is tired. Posts that have rotted along most of the line, an old fibro fence that is cracking, or panels that no longer hold in the wind are signs that patching will keep costing you. Old fibro may contain asbestos, so removal is work for a licensed asbestos removalist, not a weekend job.

The fencer confirms which way to go once they have seen the fence, the posts and the soil. Sandy ground and strong afternoon wind both shape how deep and how solid the new posts need to be.

Pick something both households can live with for years. Colorbond is steel sheeting that holds up well to sun and wind with little upkeep. Timber gives a warmer look but needs more care over time. Aluminium slat and batten adds privacy with a modern finish.

Privacy and security matter on both sides of a boundary, so height and gaps between panels are worth discussing. Property value and kerb appeal count too, because a straight, matching fence lifts how both homes look from the street.

If you are also replacing a gate, the same fencer can build the run and gate together so they match and swing properly.

A qualified fencer measures the line, looks at the existing posts and gives you a written price before anything is dug. That one figure is what you and your neighbour split, plus any upgrade one side wants.

A quote sets the agreed scope. It does not remove every surprise, such as buried rubble or a hidden old footing, but the fencer talks you through those on site.

If you have been let down before by fencers who measured up and vanished, or took a deposit and went quiet, a clear written scope gives you something to hold the job to. Tell the fencer about the fence you want, the neighbour's wishes and the suburb, and request your quote.
