The legal age of majority in Louisiana is 18, so a 17-year-old child would not be able to independently move out. Children over 18 can still receive child support if they are attending school as full-time students or for a number of other reasons.
18 is the age of majority in most states in the United States. After this point, children can legally move out on their own and seek unrestricted independent employment without the possibility of facing legal consequences.
Before 18, children are subject to the rulings of their parents or, in the absence of a guardian, of the state. This restricts their actions and their rights.
