There is no single form, because the facts vary by each case. Your posting does not state how long it has been since the default judgment was entered, how and when you first learned about the judgment, where service was performed and your relationship (if any) to that address at the time of service. That is why the Judicial Council has no form to make setting aside a bogus default judgment, because the facts can vary so widely. I also suggest that you attached to your motion documentation showing that this was not served at a valid address or that you were not personally served.
I think that for such a large judgment, you ought to hire counsel to do this for you, preferably an attorney who regularly defends consumers in debt collection lawsuits. You may be pleasantly surprised, if you contact the attorney that they are not as costly as you had imagined. My concern is that if you lose your motion, then you will owe $13,000, less credits from your bank box.
