If you break the law, you will be tried as an adult and can be sentenced to an adult prison. Unless a court orders otherwise, your parents are not required to support you, so you may have to support yourself. In addition, because you can make binding agreements with others (called contracts), you can also be sued. People over 18 may be called to jury duty. Males must register for the selective service. See generally § 743.07, Fla. Stat.
