Fencing and Boundary Disputes in Court in South Australia

Fencing disputes between neighbours in South Australia start with a notice, not a court case. But when the notice process breaks down — one side ignores it, or the two sides can't agree on the cost, type, or location of the fence — the dispute lands in the Magistrates Court as a minor statutory proceeding under the Fences Act 1975 (SA). The process is different from a standard money claim, with its own forms and a shorter response deadline.

How a Fencing Claim Reaches Court

Before filing in court, the neighbour who wants a fence built or repaired must give you a written notice — a fencing notice under the Fences Act — setting out what they propose, the estimated cost, and who they say should pay what share. You get a window to respond, negotiate, or object.

If that fails, the next step is court. The neighbour files a Form 2A Originating Application (the fencing-specific version of the Form 2) at the Magistrates Court. This is a minor statutory proceeding, which means it sits in the Minor Civil Claims Division alongside standard money claims, but follows the originating-application procedure rather than the statement-of-claim procedure.

Your Response Deadline: 14 Days

This is the critical difference from a standard minor civil claim. When you're served with a Form 2A originating application, your response deadline is 14 calendar days — not the 28 days you'd have for a Form 1 money claim.

If you wish to oppose the application, you need to file and serve a response within those 14 days and attend the hearing listed on the application:

• A Form 56 Response setting out your position
• A Form 12 Affidavit if you rely on facts additional to or contrary to those in the application (for example, photos, quotes, surveyor reports, or correspondence with the neighbour)

The 14-day window is strict. If you do not respond or attend, the Court may proceed in your absence and make orders finally determining the proceeding, including as to costs, without further warning.

What the Court Can Order

The Magistrates Court has broad powers under the Fences Act to resolve fencing disputes. It can order:

• Who pays — the default position is equal sharing, but the court can adjust this based on the circumstances (for example, if one owner's actions damaged the fence, they may pay more)
• What type of fence — if you disagree about whether it should be colorbond, timber, or something else, the court decides what's reasonable for the area
• Where the fence sits — if there's a boundary dispute, the court can determine the location
• Work to be done — the court can order one party to carry out or arrange the work by a specific date

For retaining walls, the analysis is similar but more complex. The Fences Act applies to retaining walls in some circumstances, but retaining wall disputes can also involve common law claims for trespass or nuisance — separate from the Fences Act procedure. If your dispute is about a retaining wall, check whether the application is under the Fences Act or under general common law, because the response forms and deadlines differ.

Fencing Disputes vs Standard Money Claims

The $12,000 Threshold

Fencing disputes in the Minor Civil Division are subject to the standard $12,000 jurisdictional limit. If the cost of the proposed fencing work exceeds $12,000, either party can elect under Section 3(4) of the Magistrates Court Act 1991 to move the case out of the minor civil track and into the General Claims Division, where formal pleading rules apply and legal cost recovery is available.

Most residential fencing disputes fall well under $12,000 — a standard residential fence costs a few thousand dollars. But if the dispute involves a long boundary, difficult terrain, retaining walls, or a commercial property, the figure can climb.

Practical Steps If You've Been Served

1. Check the deadline immediately. You have 14 days, not 28.
2. Read the Form 2A carefully. What is your neighbour asking for? What amount are they claiming?
3. Gather your evidence. Photos of the current fence (or lack of one), any quotes you've obtained, a copy of the fencing notice you received, and your written response if you sent one.
4. Get a competing quote if you disagree with the cost or type of fence proposed.
5. File and serve the Form 56 on CourtSA or at the registry before the deadline; file and serve a Form 12 as well if you rely on additional or contrary facts.
6. Attend the hearing listed on the Form 2A.

Even if you agree that a new fence is needed but disagree about the cost or type, you should still file a response setting out what you propose instead. Silence is treated as having nothing to say.
