Dividing Fences in Western Australia: Notice, Cost and the Magistrates Court
Western Australia’s dividing fences process runs under the Dividing Fences Act 1961 (WA). A fencing notice gives the adjoining owner 21 days to agree; disputes go to the Magistrates Court, and an owner who has already built a sufficient fence can claim half its value.

Jurisdiction scope: This page covers dividing fences law in Western Australia only, under the Dividing Fences Act 1961 (WA), verified 21 July 2026. It does not cover other Australian states or territories, each of which has its own Act; see the linked comparison page for those.
Governing law and the Magistrates Court
Dividing fences in Western Australia are governed by the Dividing Fences Act 1961 (WA). Section 5 defines "court" for the purposes of the Act as the Magistrates Court, which is the forum for a fencing dispute in Western Australia, rather than a specialist tribunal such as those used in New South Wales, Queensland or the ACT.
Notice and the 21-day response period
Section 9(1) sets Western Australia’s response period at 21 days. If, within 21 days after the giving of a notice referred to in section 8, the owner who gave the notice and the owner who received it do not agree on the need for the fence, the boundary or line on which it is to be built, or another listed matter, either owner can bring the dispute to the Magistrates Court.
Cost sharing: a distinctive half-value claim
Western Australia’s approach to cost is structurally different from most other states. Section 13 allows an owner who has constructed a sufficient dividing fence, whether or not a notice under section 8 was given first, to claim half of the fence’s value from the owner of the adjoining land. Rather than an up-front equal-contribution agreement negotiated before construction, this lets the fence be built and the cost-sharing claim made afterwards, within the framework the section sets out.
What the Magistrates Court can decide
Where the owners cannot agree, the Magistrates Court can resolve disputes about whether a fence is needed at all, the line on which it should be built, and the type of fence, drawing on the matters identified in section 9(1). The Court’s role, and Western Australia’s single-forum, court-based model, mirrors Victoria and South Australia rather than the tribunal-based states.
Starting the process: the notice to fence
An owner who wants to compel a neighbour to contribute begins with a notice to fence under section 8. The notice must specify the boundary to be fenced, or, where the physical features of the land make fencing directly on the common boundary impracticable, the alternative line proposed, along with a proposal for the fencing itself and the kind of fence proposed. This gives the adjoining owner a clear, specific proposal to respond to within the 21-day window in section 9, rather than a vague request to "sort out the fence," and a well-drafted notice under section 8 is the foundation for everything that follows if the matter later reaches the Magistrates Court.
Repairing an existing fence
The notice and half-value claim provisions described above are mainly concerned with building a fence where none, or an insufficient one, currently exists. Repair is treated separately: section 14 makes owners on either side of a fence in need of repair liable, subject to section 15, to join in or contribute in equal proportions to the repair. This equal-proportions default for repair work is a more conventional, up-front cost-sharing rule than the half-value claim used for constructing a new fence under section 13.
If the adjoining owner cannot be found
Section 11 addresses a situation the standard notice process cannot resolve on its own: what happens where the adjoining owner genuinely cannot be located. If an owner satisfies the Magistrates Court nearest to the proposed fence that they have made reasonable inquiries but have been unable to ascertain the adjoining owner's whereabouts for the purpose of giving a section 8 notice, the Court can proceed ex parte, meaning without the other owner present, and make an order authorising the applicant to construct the fence on the boundary specified. This lets a Western Australian owner move forward with a needed fence even where the neighbour cannot practically be given notice, rather than leaving the fence indefinitely unresolved.
How Western Australia compares
Western Australia is one of only three jurisdictions using a Magistrates Court rather than a tribunal, alongside Victoria and South Australia, and its half-value claim mechanism under section 13 is not replicated elsewhere in Australia. See dividing fences in Australia for the full comparison, and dividing fences in South Australia for another Magistrates Court jurisdiction with a different notice process.

Frequently Asked Questions
How long does my neighbour have to respond to a fencing notice in Western Australia?
21 days after the notice under section 8. If the owners do not agree within that time on the need for the fence, its line, or its type, either owner can take the matter to the Magistrates Court under section 9(1).
Can I make my neighbour pay for a fence I already built in Western Australia?
Section 13 allows an owner who has built a sufficient dividing fence to claim half its value from the adjoining owner. This is a distinctive feature of the Western Australian Act compared with most other states.
Which court decides a fencing dispute in Western Australia?
The Magistrates Court, as defined in section 5 of the Dividing Fences Act 1961 (WA). Western Australia does not use a specialist tribunal for fencing disputes.
Does Western Australia have a tree-dispute law?
No. Western Australia has no dedicated tree statute. A tree problem there is governed by the general common law of nuisance and the self-help right of abatement.
What can be disputed about a dividing fence in Western Australia?
Section 9(1) covers disagreement about whether a fence is needed at all, the boundary or line it should be built on, and the type of fence to be constructed.
What should a fencing notice in Western Australia include?
Under section 8, it must specify the boundary to be fenced, or an alternative line if fencing the common boundary is impracticable, along with a proposal for the fencing work and the kind of fence proposed.
