Only with parental consent.
No, the parents are responsible for him until he is 18.
No
Only if they have their parents' permission.
I am not a US citizen so I don't know about the state laws of Florida. However, I can tell you for certain that you should not leave a 10 year old child home alone (legal or not!).
Either with parental permission or emancipation by the court if that is available in your state.
In Kansas, the legal age of majority is 18. A 17-year-old who leaves home without parental permission may be considered a runaway. If the minor can demonstrate to authorities that they are capable of making independent decisions and supporting themselves, they may be allowed to live on their own.
In the state of Idaho the age in which a person may get emancipated is 16. Therefore, it is legal for a 17 year old child to file for emancipation.
No, you can not leave home at 17 to move in with a 20 year old male.Because, the 20 year old could go to jail for being 3 years older than the 17 year old.
No, the legal age of majority for the state is 18.
No they may not do so. They are not an adult yet.
No, they must have permission. Otherwise they are a runaway and the police can return them to their home.
I think, if they're not alone for more than a few minutes.
