Neighbor has a 4ft diameter oak tree 15 feet from lot line. Has about a half dozen dead branches 6 in diameter that are 20ft into my yard and a young tree of mine is fighting through them. If I discuss cutting with neighbor he will try to leverage me into doing favors for him and these will linger on for a long time. If I can't cut them Id rather let nature take its course than deal with neighbor. What is Indiana law regarding trimming branches overhanging in your yard?
