what age can a child legally leave home in missouri
Report Abuse. In Missouri, a child that leaves home at a minumum age of 17, cannot be forced to move back home-although his/her parents are still legally responsible for them until they are 18.s long as you and the mother agree, along with the grandparents, it's legal for your 15 year old to live with them. If you feel better, you could go to court and give them temporary custody, in case they have to take the child/teen to the doctors.
