A 17-year-old is legally permitted to move out of his home in the state of Michigan. However, this is only legal because of a loophole in Michigan law, according to LawRefs.com.
In the state of Michigan, 17-year-old persons are not classed as adults, minors or juveniles. However, parents are required to support children until they reach age 18. This becomes complicated if the child chooses to move out at 17. A parent is unlikely to receive police assistance if their 17-year-old child chooses to leave or to run away because the child has the legal right to live on his own.
