We are constructing a building in a plot that we own.. Neighbour`s coconut tree has bent so much that it obstructs construction in our plot (the crown of that tree is in the space that we want to construct sunshades).As shown in the images, the tree has swayed and even moved the compound for a feet. i asked them to remove the tree so that we could proceed with the construction. (Cutting just the branches was out of question as it wud kill the tree eventually)They rejected our plea. Pls advise what i can do further..
