Is there anything your parents or the police can do to stop you from leaving the house once you're 17 in the state of Missouri?
Yes, the age of majority in Missouri is 18, although many believe it to be 17. The confusion comes from the rather oblique way the law is written. A persons who are under 18 but are married and/or serving in the military are considered emancipated. For all others is 18 also adding somewhat to the confusion is the age of sexual consent which is 17.
