My neighbour has a gigantic tree in her small garden (think like 60 ft) and it spreads and overhang mine considerably. She is elderly and I understand the problem in maintaining it and the costs etc. My kids were at a loose end and made a rope swing on one of the branches, and she was furious, threatening to call council etc. The branch was on my side! Has she any right to do this? My understanding is that any parts of a tree overhanging the boundary are that person's to do what they like with - you could cut them back to the fence if you wanted? Isn't that the case? The tree is a bloody pain tbh, massively overshadowing, and every autumn I spend hours sweeping up leaves from my swamp of a garden because of it - no help offered from her family, naturally.
