You should file a Motion to Set Aside the Default if it has in fact been entered by the Court. If there was in fact fraud (which there are not enough facts to determine there was at this point), that can be used in the facts as well. These motions are extremely time sensitive so you should contact a local lawyer to determine if the Statute of Limitations has passed.
You need a good lawyer to discuss the particulars of your situation with you. It is important to read documents carefully before signing them.
