If you are having issues with trees, hedges and leaves
Issues with leaves
If your property is covered in leaves from a tree that doesn't belong to you
The legal view is that once a leaf falls from a tree it belongs to no one as you cannot determine its flight path, due mainly to the vagaries of the wind and weather.
The law also has determined that it is not unreasonable to expect you to clear up leaves, if you live in an area where there are trees.
