I have already cut the offending growth away.
I think you mean that he istaking legal advice. Excellent.
In which case, his legal adviserwill tell him that you can do exactly what you have done and that his hedge isa nuisance.
This is a very common question. Aperson cannot make an adjoining property owner cut the trees per se but pleasesee my later comments about trespass and nuisance.
Consent is needed to trimdeciduous trees which are protected by a Tree Preservation Order and a licencemay be needed to fell trees which are not protected by a TPO.
Evergreens cannot usually have aTPO.
Regarding evergreens, a complaintcan be made to the council and they will deal with them under the nuisance treelegislation but only with regard to the height. They want £300 fee to start the process and if theyfind that the trees are a nuisance, they can compel a tree owner to cut themdown to 2 m high.
With regard to branches and rootsgrowing boundary,(evergreen or deciduous) these are nuisance and trespass. Theoverhanging pieces can be chopped off as can roots growing underground but theydo not belong to anyone other than the tree owner, so the pieces should begiven back although if they are unceremoniously dumped over their hedge withoutwarning, it is not good for already fraught neighbour relations.
The following are links will giveyou some reading with regard to high hedges and nuisance trees. Don't worryabout where the sites are geographically because the rules apply nationwide.
Does that answer the question?Can I answer any further points?
