The way you go about suing anyone is to hire a lawyer to do it. But IMO you have no grounds for a lawsuit.

you have a lawyer. You should ask them...............

We don't know why. Ask the lawyers who are suing you.

You have nothing to sue for. Get a refund.

He is asking you to commit fraud...............

None of us can tell you the "why." If you feel the loan is illegal contact your state Attorney General.

No you cannot sue the AGC.......................

No. It is your lawyer's job to file a motion to suppress.

This is a Q&A forum. You have not asked a question.

This is not a legal issue. Don't use credit cards.
