A client comes into your office.  He has been paying child support for ten years for his son who does not live with him.  He just found out from a friend that the son, who is eighteen years old, dropped out of Boone High School in Orlando, Florida, and joined the Army.  Since the U.S. Government is feeding and clothing him now, why should he still have to pay child support?  Does he?  Find the statute that answers this question using Lexis.
