Don't quite understand this thread to be honest. Look you wanted to know where you stood legally, basically until damage is being done you need to do nothing, but seem to be looking for validation of your actions also.
Why do you keep saying this?
The op asked if he is legally required to cut branches overhanging into a neighbours property, the answer is you are not legally required to do anything on another persons property. The neighbour can cut what overhangs the boundary, but the op does not have to cut their side.
Whether he should, or not is a subjective opinion, but not one based on obligation. If your neighbour is a dick and has made life difficult, then not many people are inclined to do a good deed for them, so spare us the moral outrage please.
