First, you need to be clear on what exactly she was served with. Judgment papers implies that a judgment has already been awarded to the plaintiff in a law suit. Generally, one isn't' "served" with such. It could be a summons notifying her that a suit has been entered against her. That sounds more likely if there is a future court date. However, generally a court date is not set until the defendant responds to the summons. So you need to determine what it actually is.
Second, in either case, if it has gone as far as being sued her credit is already in the tank.
Finally, any chance on getting out of it depends on what it is, whether she actually owes the debt, who is suing etc. So more info is needed to help.
