Tree foliage blocking sunlight, roots blocking drains, overhanging branches or damaging roots from a neighbour's tree can be a source of conflict between neighbours.
Often property owners approach Council with their concerns hoping that Council will resolve the matter.
Unfortunately, Council is unable to intervene in private tree disputes between you and your neighbour as it is a civil matter.
If you wish to prune any overhanging branches from your neighbour's tree you may need to apply to Council before you carry out any tree works.
If this is unsuccessful you can lodge an application with the Land and Environment Court under the Trees (Disputes between Neighbours) Act 2006.
