My recollection of basic tree law is that if the debris or tree falls accidentally that you are liable only if you knew or should have known of the likelihood of the debris faling.
Neighbours leaves in gutters.
Covering the gutter is the easiest option which relies on surface tension to direct water back into the gutter while preventing leaves from falling in.
Keep in mind this is a more expensive option.
It s an act of god as to where the leaves fall.
Only problem with this is the amount of leaves branches that drop into the yard and also into the gutters.
Leaves in neighbors gutter.
The types of gutters you have can also play a role.
If you were looking to replace your gutter system any way you can go with a permanent solution.
The neighbor isn t responsible for.
However leaves falling in the normal course of fall it s up to the property owners to remove such.
There is a line of council trees growing outside the fence line which i do enjoy for the shade and greenery.
Even if the leaves cause damage like clogging your gutters or pipes you have no legal claims against the owner of the tree.
But you aren t legally responsible for that debris in the yard next door.
I have had to get the gutters cleaned 5 times in the past calender year due to the amount of leaves clogging up the gutters.
I m not sure how that applies to your situation but it seems that there is probably no strict liability.
When leaves fall from your tree and create debris in the yard next door your neighbor might find it annoying.
If however the tree branches that are shedding the leaves are hanging over your yard or the tree trunk is encroaching on your property then you have a right to trim those branches up to the property line.
Certainly if the neighbor specifically went up and placed leaves in your gutter they would be responsible for their removal.
