A neighbour’s tree branch crashes through your roof during a storm. Their poorly maintained retaining wall collapses into your backyard, taking out your fence and garden shed. Tree roots crack your driveway so badly it needs replacing. These are the kinds of external damages that test the boundary between a polite conversation and a formal insurance claim. In NSW, property damage from neighbours usually falls under negligence, trespass, or private nuisance — and each one has different rules about whose policy pays and how you prove it.

What these numbers tell you is that the value of your damage shapes every decision that follows. A claim under $20,000 stays in the small claims division where you don’t need a lawyer. Above that, the cost of legal representation starts eating into whatever you recover. Your insurance policy may cover the damage directly, but the question of who caused it — and whether your insurer pursues the neighbour for reimbursement — depends on how well you can prove what happened. That’s where most people get stuck.
Here’s what you actually need to know.
The central legal concept here is private nuisance — when a neighbour’s use of their land unreasonably interferes with your enjoyment or use of your property. Courts assess this by looking at the locality, duration, severity, and what a reasonable person would consider unacceptable.
What I tend to notice is that people assume “nuisance” covers any annoyance from a neighbour. Legally, it has to be substantial and unreasonable — not just irritating. If you’re thinking about claiming on your insurance, the first question is whether the damage fits the legal definition of nuisance, negligence, or trespass. That determines whether your insurer can recover costs from the neighbour later.
Court thresholds and what they mean for your claim value
The value of your damage decides not just whether you claim on insurance, but which legal path is realistic if you need to pursue the neighbour directly. In NSW, the court system has clear dollar limits, and they affect how much sense it makes to involve lawyers.

| Court Division | Claim Value | What It Means for You |
|---|---|---|
| Local Court — Small Claims | Up to $20,000 | No lawyer required; simpler process; lower filing fees |
| Local Court — General Division | $20,000 – $100,000 | Legal representation common; more formal procedures |
| District Court | $100,000 – $750,000 | Full legal process; higher costs; longer timelines |
| Supreme Court | Over $750,000 | Complex cases; significant legal costs; specialist judges |
If your insurance covers the damage, your insurer will decide whether to pursue the neighbour for recovery. That’s called subrogation, and it’s their right, not yours. But if the damage is below your excess, or if your policy excludes the cause, you’re looking at a direct claim against the neighbour. In that case, the court thresholds above tell you what you’re up against.
One thing worth weighing: if your damage is gradual — say, roots cracking a driveway over three years — many insurers classify that as wear and tear and won’t pay. The legal claim for nuisance might still succeed, but you’d need to prove the neighbour knew about the roots and did nothing. That’s a higher bar than most people realise.
Common errors when dealing with neighbour damage and insurance
Assuming your insurance covers all external damage
Home insurance policies typically cover sudden and accidental damage — a tree falling on your roof, a storm blowing tiles off. They don’t cover gradual damage from tree roots, subsidence caused by poor drainage, or wear and tear on fences. The Law Handbook notes that cracked driveways from tree roots are notoriously difficult to prove as caused by the neighbour’s tree, which means insurers often reject those claims. Before you lodge a claim, check whether your policy lists “gradual deterioration” or “maintenance” as exclusions. If it does, the claim will likely be denied, and you’ll have to pursue the neighbour directly.
Failing to document the damage properly
Courts and insurers both require clear, dated photographic evidence of the property before and after the damage. A chronological series showing progressive deterioration — like a crack widening over months — is far more persuasive than a single photo taken after the fact. Expert reports from engineers, building inspectors, or arborists carry significant weight, especially if they confirm the cause and extent of the damage. Keep a “nuisance diary” recording every incident, communication, and step you’ve taken. Without this paper trail, you’re asking the insurer or the court to take your word for it, and that rarely works.
Going straight to legal action without talking to the neighbour
Litigation is expensive, time-consuming, and permanently damages your relationship with the neighbour. The first step should always be a conversation — ask them to fix the problem or remove the cause. If that fails, a letter of demand drafted by a solicitor can be surprisingly effective. Community Justice Centres offer free mediation for neighbour disputes, and even if mediation doesn’t resolve everything, it can clarify the issues for court. The research from Kerin Benson Lawyers makes clear that litigation should be a last resort, not a first response.
Not understanding the nuisance threshold
Not every annoyance is a legal nuisance. Courts balance your right to enjoy your property against your neighbour’s right to use theirs. The interference must be substantial and unreasonable — disrupting basic domestic functions like sleep. Feeding birds at night causing noise pollution was described by one court as likely sufficient for a nuisance. But a neighbour mowing their lawn at 8am on a Saturday? That’s normal use. If the damage is minor or the interference is trivial, you won’t get a remedy, and you’ll have wasted time and money pursuing it.
How to handle a neighbour damage situation and your insurance claim
Assess the damage and check your policy first
Before you do anything else, work out what happened and when. Sudden events like a tree branch falling in a storm are more likely to be covered. Gradual damage from roots or water runoff is often excluded. Read your policy’s list of exclusions carefully — if “gradual deterioration” or “lack of maintenance” is mentioned, your claim will probably be rejected. If you’re unsure, a quick call to your insurer asking “does my policy cover damage from a neighbour’s tree?” without lodging a formal claim can give you a clearer picture without risking a premium increase.
Document everything before you contact the neighbour
Take dated photos of the damage from multiple angles, including shots that show the damage in relation to the neighbour’s property. If the damage is ongoing — like a crack getting wider — photograph it weekly. Collect repair quotes from licensed tradespeople. If the cause is technical, consider an expert report from an engineer or arborist. Keep copies of all correspondence with the neighbour, including emails, texts, and notes from phone calls. If you end up in court or making a formal insurance claim, this evidence is what decides the outcome. A video doorbell camera can also help capture evidence of ongoing issues like trespass or debris entering your property.
Talk to the neighbour and consider mediation
Most neighbour disputes resolve without lawyers or court. Explain the damage calmly, show them the evidence, and ask them to fix the problem. If that doesn’t work, send a letter of demand outlining the facts, the legal basis for your claim, and what you want them to do. Set a reasonable deadline. If they still don’t respond, Community Justice Centres provide free mediation under the Community Justice Centres Act 1983 (NSW). Mediation is confidential, costs nothing, and often preserves the relationship better than a court case. Even if it doesn’t resolve everything, it clarifies the issues.
When to claim on insurance and when to sue
If your insurance covers the damage, lodge a claim and let your insurer handle the recovery from the neighbour through subrogation. If your policy excludes the damage, or if the excess is higher than the repair cost, you’re looking at a direct claim against the neighbour. For claims under $20,000, the small claims division of the Local Court is the most practical option — no lawyer needed, lower fees, faster process. For claims above $20,000, legal advice becomes more important. A legal service can help you assess whether your case has merit before you commit to a costly court process.
Upcoming changes and what to watch for
NSW legislation around strata schemes and neighbour disputes is evolving. The Strata Schemes Management Act 2015 (SSMA) section 153 already allows for orders against nuisances in strata properties, and there’s growing pressure to extend similar protections to standalone homes. If you live in a strata complex, your by-laws may already give you a faster path to resolution than the general law. Keep an eye on any amendments to the SSMA or the Community Justice Centres Act — they could change how you pursue a claim.

Know your options before you act
The most common mistake is rushing to a formal claim or legal action without first understanding what your policy covers and whether the damage meets the legal threshold for nuisance. The research from NSW legal sources makes one thing clear: evidence is everything. Without dated photos, expert reports, and a clear record of your communication with the neighbour, you’re relying on your word against theirs. That’s a weak position in any forum.
