My neighbours pine trees are approximately 20 ft tall, the branches overhang my boundary wall and the roots have also grown under the boundary wall. I recently had my drive black topped, but now these roots are cracking the drive and also I have to sweep the pines from my drive every week. Neighbour has promised to do something about it but I don't think he will. What are my rights around cutting back the overhanging branches ? Or better still remove the trees completely as the roots will in time destroy my black top
