What is the legal age to move out in Missouri?

The legal age of majority for the state of MO. is 18. Missouri has a law that designates a 17-year old as being an "adult" for adjudication purposes only. Which means a 17-year old is considered an adult when it pertains to certain criminal offenses, and therefore can be tried in an adult court. The age cited in the juvenile code does not supercede the established legal age of majority which is indeed, 18-years of age. In MO. as in all states that have enacted laws or participate in AMBER ALERT, law enforcement must take action to find the missing minor as soon as a report is made, there is not a "waiting period." Cases in which the whereabouts of the minor is known are handled differently.

Answer

The age of majority is 18. That's when you're considered a legal adult and you can make all your own decisions. In some cases a minor can be legally emancipated. You would want to contact a family lawyer in your local area to ask about this. Otherwise you can't leave home without parental permission until you are 18-years-old.

Answer

There is some misunderstanding about MO. age of majority law, MO. law does not have an emancipation statute as such. The age for becoming an adult in Missouri is 18. RSMO 210.110 (3) "Child" any person regardless of physical or mental condition under 18 years of age. RSMO 660.400 (1) "Adult" any individual over the age of 18 years. The laws are written as such because MO. child support orders are in most circumstances valid until the "child" is 21.
