The Queensland Government has an online step-by-step guide to resolving tree disputes.
If you have tried talking to your neighbour but the matter remains unresolved, you can provide them with a notice to remove particular branches.
If you are unable to resolve a dispute about payment for the cutting and removal of overhanging branches, you may apply to QCAT to recover up to $300 as a minor debt dispute.
If your matter is a minor debt, you can save time and complete a minor debt application (form 3) and pay online. You will still need to lodge a copy of your application at a QCAT registry.
