Adulthood also brings new responsibilities and consequences. Your parents no longer have to support you. You can now be sued personally. You are responsible for paying your own income taxes. You must register for the military if you are a young man. And if you commit a crime, you will not have the protection of the juvenile court and laws; you could wind up in jail for something that, at a younger age, might have resulted in no more than a stern lecture and a ride home in a police car.
This guide touches on some of the laws that may apply to you at this turning point. Keep in mind that laws are constantly subject to change. If you have a specific legal problem, you may want to consult an attorney.
