My garden backs on to a river. There is no bank on this side of the river. The trees growing on this side are massively overhanging my garden and branches keep coming down. I contacted the council but they are not responsible. I have done a land registry search and the company that apparently owns the land was liquidated. Surely someone/a company has to be responsible. I could get the branches cut down that are overhanging (probably my only real option) but the quotes are well over £10k.
