In most states, the legal age to move out of a parent's home is 16 because this is the legal age of emancipation, according to FindLaw. This age varies from 14 to 17, so minors wanting to leave home should check with the court in their own state.
To become emancipated, a minor must demonstrate a maturity that proves to the court that he or she can be self-sufficient and responsible. A minor must also prove to the court that financial independence is possible, but it is important to note that the parents have the right to contest the emancipation request.
Although emancipation allows a child to move out, it does not grant other adult freedoms such as voting or drinking alcohol, as noted by FindLaw. A child can move out of the home with no legal proceedings at the age of 18.
