A 17 year old in Pennsylvania can simply sign a petition at a Family Court for emancipation, if they are working. Once the petition is signed and submitted, there will be a date set for a hearing with a Judge.
The 17 year old must have proof of a job and a checking account for this hearing. They must also have evidence that they have the necessary funding required to be self-supportive. This evidence must be submitted at the hearing. It is then left to the Judge's discretion whether the 17 year old may be emancipated under the law in PA.
Only a 17 year old minor can petition the Court for emancipation. The parent is not allowed to do so.
