With parental consent yes, and it also matter how old they both are.
In Illinois, a 17-year-old can live with an adult sibling if the sibling is willing to provide care and support for the minor. However, it is advised to consult with a legal professional to ensure that all necessary steps are taken to establish a suitable living arrangement.
I'm pretty sure you have to be 18 to move out. That is the legal age (to be considered an adult). 16- minor
The Aunt can be named a guardian, however this dos not prevent a custody challenge by the other parent.
The minors parents need to give the adult sibling with whom the minor is going to live a notarized document containing all pertinent information. It should have the date when the arrangement begins and the approximate date it ends if it is before the minor reaches the legal age of majority (18). It should give the adult sibling the authority to enroll the minor in school, obtain medical and dental procedures, state the financial arrangements (if any) and so forth. The parents are legally obligated to remain in contact with the minor and the minor's adult caregiver on a regular basis.
It depends on where you live and how old the minor is.
US Only: No. In fact, it is mandatory.
Having a child does not change the fact they are a minor. A minor remains the responsibility of the parents. Once they are an adult, they can live where they want to.
It's highly unlikely that authorities would intervene in such a situation unless the adult sibling placed the minor in a situation which could jeopardize said minor's welfare. The legal definition of "harboring a runaway" would not apply in such circumstances as long as the parent(s) were made aware of the minor's whereabouts.
No, it is not illegal to live alone as a adult student.
The law is the law and if it is being broken, anyone can report it.
If you are a minor child, yes you must live at home unless Children's Services determines you should not, OR until a Court / Judge determines you should not live there. If you are an adult, an adult can live where he/she pleases.
If you live in the US....no. Having a child does not emancipate a minor.
