When a tree falls on a car, damages a fence, cracks a foundation, or injures a person, the question of who pays for the damage is often more complicated than people expect. Liability depends on the circumstances, the relationship between the parties, and whether anyone was negligent in maintaining the tree.
General Principles of Tree Damage Liability
In Australian law, the owner of a tree is generally responsible for ensuring it does not cause harm to others. This duty of care means tree owners must take reasonable steps to maintain their trees in a safe condition. If a tree causes damage and the owner knew or should have known about the risk, they can be held liable for the resulting losses.
However, liability is not automatic. Natural events such as severe storms can constitute an “act of God” defence if the tree was in reasonable condition before the event. The key question is whether the damage was foreseeable and whether the tree owner took reasonable precautions. An arborist report can be crucial evidence in determining the tree’s condition before the incident.
Common Liability Scenarios
Your Tree Damages Your Neighbour’s Property
If your tree falls onto your neighbour’s fence, shed, or house, you are likely liable if the tree was in poor condition and you failed to maintain it. If a healthy tree was brought down by an extraordinary storm, you may not be liable. Your neighbour would typically claim on their own insurance, which may then seek recovery from you if negligence is proven.
A Neighbour’s Tree Damages Your Property
The same principles apply in reverse. If your neighbour’s tree damages your property, you should document the damage, notify your neighbour in writing, and lodge a claim with your own insurer. Your insurer may then pursue your neighbour for reimbursement if there was negligence.
Council Trees Causing Damage
Local councils have the same duty of care as private tree owners. If a council-managed tree on a nature strip or in a park causes damage, the council may be liable. However, councils typically have processes for reporting tree hazards, and proving they knew about the risk is essential to establishing liability.
Trees on Rented Properties
On rental properties, tree maintenance is generally the landlord’s responsibility. If a tenant reports a hazardous tree and the landlord fails to act, the landlord may be liable for any subsequent damage.
Protecting Yourself from Liability
The best protection against tree damage liability is proactive maintenance:
- Have trees inspected regularly by a qualified arborist, especially large or mature specimens
- Respond promptly to any signs of decline, disease, or structural weakness
- Keep records of all inspections, maintenance, and any reports
- Act on recommendations from arborists, including removal if advised
- Ensure your home insurance and public liability coverage are adequate
