The Colorado Supreme Court has held that an owner may remove a tree on her own land even if it has grown over the borderline onto neighboring land even if the neighboring owner objects to removal of the tree. Love v. Klosky,2018 CO 20, 413 P.3d 1267 (Colo. 2018). In contrast, a border tree that was planted on the border itself becomes the joint property of both neighbors and cannot be removed with the consent of both of them.
