>>Speaking as an arboriculturalist, I can tell you that not many trees are properly 'checked'.
I am sure that you're correct. However, it would not be reasonable to expect every tree to be inspected to an arboriculturalist's standards.
It should be checked as far as is reasonable with an expert called in if there is doubt or risk.
Anyway, that's a bit besides the point, hence use of the word "if".
You can only claim against another person if they were liable, where "liable" virtually always means "negligent".
Ownership is not sufficient for liability per se.
