Can you live by yourself at 15 years old?

Yes, you can. However, in most states a minor (a person below the age of 18) must get emancipated.

Emancipated is when a minor legally divorces (lack of better Words) their parents or guardians. The procedure does not take long, but a lot of paperwork. Mainly, the child must prove that they can take care of themselves.

To do this, usually the minor must

-have a job,

-still be in school getting an education,

-able to pay for their own rent (living expenses),

-and shows a good sense of responsibility to take care of themselves.

Another way is if the the minor is rich. That is sure proof they are able to pay for themselves.
