The Shades of Spring, When Your Neighbour’s Tree Thinks It Owns Your House

September 10, 2025

By Melly Shute


Spring has arrived in the inner city and with it comes sunshine, hay fever, and inevitably, tree disputes. You might think of trees as harmless, leafy air-purifiers, but in property law, they can become the quiet villains of the street.

Overhanging Branches

Picture this: you’re sipping coffee in your courtyard when a giant branch from your neighbour’s gum tree casually swan-dives into your garden. Suddenly, your Sunday turns into a crash course in arbor law.

 

The law is clear: the tree belongs to your neighbour, but you are entitled to protect your land from encroachment. At common law, you may cut back overhanging branches up to the boundary line (Lemmon v Webb [1894] AC 1). However, you must not trespass onto your neighbour’s land or cause damage to the tree, doing so could expose you to liability. Importantly, the branches you remove technically remain your neighbour’s property, so you can’t just toss them into the green bin and pretend they never existed.

Encroaching Roots

Roots are a different beast. They’re like those mates who “just pop by” and end up staying the weekend. If a neighbour’s tree roots damage your drains, crack your foundations, or ruin your veggie patch, you may have a right to recover the cost of repairs. Courts have confirmed that a landowner can seek damages or an injunction if encroaching roots cause actual harm (Kaitler v Bayside City Council [2012] VCAT 918).



That said, hacking away an entire root system is risky business. If the tree dies or becomes unsafe because of your actions, you could be held responsible.

Talk Before You Chop

The golden rule? Talk before you chop. Many disputes can be resolved with a simple conversation (and perhaps a six-pack). If that fails, legal remedies exist, including applications under the Fences Act 1968 (Vic) or proceedings at VCAT or the Magistrates’ Court.

Adding another wrinkle, some trees are protected under local planning schemes or heritage overlays. Removing or even significantly pruning them without council approval can result in fines much greater than the cost of mediation.

The Takeaway

So this spring, before you declare war on your neighbour’s overhanging branches, remember: while trees may not have rights, your neighbours and your council, certainly do. If you find yourself facing an arbor dispute, the best first step is legal advice to avoid turning a small nuisance into a costly legal battle.

The Great Australian Housing Fix That May Fix Nothing At All

April 23, 2026
By Melly Shute There are few things more reliably Australian than trying to solve a complicated national problem with a tax tweak and a press conference. This week’s idea is the possible removal of the capital gains tax discount for investment properties, a proposal that has all the ingredients of a proper local political feast: investors clutching their spreadsheets, first home buyers clutching their despair, and renters clutching whatever remains of their bond. For those playing along at home, the CGT discount is the tax rule that softens the blow when an investor sells a property for a profit. Remove it, and suddenly the tax bill gets chunkier, triggered at the contract date no less, which, in property terms, is rather like being told the music stops before you have even put the champagne back in the fridge.

Our Approach to Anti-Money Laundering and Counter-Terrorism Financing (AML/CTF)

April 2, 2026
By Melly Shute From 1 July 2026, changes to Australia’s Anti-Money Laundering and Counter-Terrorism Financing laws mean that law firms are required to complete additional identity and risk assessment checks before providing certain services. These reforms are designed to protect the financial system and prevent misuse by criminal organisations.
