Depends on how old you are but either way will you need parental permission. If it's far away from your parents someone should have temporary custody at least so they have the right to make medical decisions on your behalf in case something happens. And your friends parents would need to get child support for you from your parents. That is done in court.
Yes
In most places, a person cannot legally move out on their own before the age of 18. It is important to discuss any concerns or issues with a trusted adult or seek help from local authorities if needed. Staying with a friend's family without parental permission may not be legally permitted and could lead to complications.
Not legally. If you're parents report you missing, the police can pick you up and arrest the family.
In Texas, a 15-year-old can only move in with someone else if their parents or legal guardians agree to it. If the parents of the minor and the friend's parents agree, they can petition the court for a legal guardianship or custody arrangement. Otherwise, it would not be legally permissible.
That depends on the law where you live and whether the mother has both sole physical and sole legal custody of the child. If she does not, she would need permission of the court and the other parent to legally allow it and depending on the custody order, she may have to get the court's permission for such a move even if she has sole custody in both areas. She should consult her custody order or an attorney for more information.
No. You have to be 18 or have a legal guardian appointed. In some cases a minor may live with another adult relative or friend of the family, with the parents permission.
Not legally. But if he had the keys then yes.
If you want that also it is possible. Be careful. frying pans are better then the fire...
Legally it isn't possible without parental permission.
If both parents have custody, then they have an equal say, and you would need permission from both. If only Mom has custody, then you certainly could not move out without her consent. If only Dad has custody, then I suppose you could move in with someone else with just his consent. And Mom could then petition the court and request that she be awarded custody, and her request would very likely be granted.
No, they have not reached the age of majority for Australia. Until that time the parents have to be responsible and make the decisions.
You would be covered by the insurance on your friend's car if you are driving it with their permission. To be safe, get the parents' permission, not just your friend's. It may be that your friend can't give a legally binding permission.
