Emancipation is a legal way for children to become adults before they are 18. A child’s parents no longer have custody over someone who has been emancipated.
If you are emancipated, you can do the following without your parent's permission:
get medical care
apply for a work permit
sign up for school or college
live where you want to
receive your own survivor or disability check
sign up for housing benefits
If you are emancipated, you will give up the right to be supported by your parents. If you have a legal guardian, all the information in the above section about "parents" also applies to your legal guardian.
Even if you are emancipated:
you must still go to school
you cannot get married without your parent's permission
you will usually go to juvenile court if you break the law, but you could be tried as an adult
child labor laws and work permit rules must be followed
you cannot drink alcohol until you are 21
statutory rape laws still apply
