Neighbor cutting other neighbor's trees
Trees in my yard are overhanging my neighbor's yard. She wants me to cut them back. One branch was touching her roof which I promptly had removed.
My neighbor says she wants to cut back the branches from my tree that are over her yard and send me the bill. I believe this is against the law and that she can only trim my tree with my permission and at her own expense. Is this correct? She is also asking that I clean up the leaves in her yard. It's autumn, leaves fall. I don't think I need to do her yard work for her. She is the owner of this house which is rental property for her. Her tenants have a gardener that does the yard work for them.
Are there any laws regarding this issue?
