Neighbors trees in my yard

[Shanise Kimbrough]

Im a new investment landlord. I signed up took the 90 day challenge and recently closed on a duplex. Im looking to firstly work on the curb appeal. Currently there are trees from a next door property that has grown over a fence into my yard and and even grown within the electrical pole wires (dangerous) Whose responsibility is it to cut them back? What recourse do I have with the other owner if they refuse?
