Your situation is too involved for an online answer.
Using the written documentation you have is a good place to begin. Contact a local lawyer - many may give you a short free consultation - to discuss your specifics. Far too many variables exist in the short post you wrote for any further observation by me. Many attorneys have information posted here on Avvo.

No one can know what the record is in the case because online we cannot see your documents. You need a lawyer. Check with a lawyer in your locale to discuss more of the details.
Good luck to you.

He needs a local criminal lawyer, pronto. What he did is a felony in NY (where I'm admitted). I don't know if it's a felony or a misdemeanor in NC, but it's definitely a crime. He committed fraud, submitted false documents, lied to the State, etc. He may wind up going to jail.
His brother is in trouble, too, for giving his info to his brother, or for letting him use it. He also needs a criminal lawyer.
