Hello my name is ***** ***** I will help you.
Will shaving the trunk kill or damage the tree?
As long as you don't kill or damage the tree you are ok.
If you do kill or damage it, that is criminal damage which you can be sued or prosecuted by the police.
Remember you have to offer back any trimmings you take as they are not yours.
Can I clarify anything for you about this today please?
Correct. Does that clarify? Alex
No, it's not a joint tree. It started on your neighbours side. You need to get a tree surgeon to do the work as they are skilled.
It comes under common law so not written down.
Does that clairfy? Alex
It's common law therefore it is not written down but accepted by convention. I indicated this above it was common law if you can see it. Alex
