Ask him to see the court order declaring him emancipated.Recently, my friend's boyfriend got emancipated without meeting the requirements.
He wasn't.How was he even allowed to become emancipated without doing so?
I know dozens of people here in Ohio who claim to have been emancipated. Except, here in Ohio, we don't even allow for the emancipation of minors unless they get married or join the Armed Forces - both of which require consent of both parents.
It's not unusual for teenagers to claim to have been emancipated. The correct response to such a claim is "Really? I've been thinking about that myself. Can I see the court order?"
