My neighbor has a huge 10-12ft leylandii hedge which overhangs into our garden a good couple of foot. I would like to take it back to the stumps on our side which are on our boundary line. Will this kill our neighbours side of the hedge too? As our garden is long but very narrow that couple of foot that is overhanging make a lot of difference.

I don't think it will harm the health of the tree, but I cannot give you advice on how to prune this. Different areas have different laws, so you will have to talk to your local authorities to see what the best course of action would be from a legal standpoint.
