Can I counter sue for a false claim about a car accident that resulted in my car being totaled?

My girlfriend is being sued to pay for the damages incurred during an accident. The paperwork from the court states that the car was in someone else's name and was uninsured, but my girlfriend has the paperwork proving she bought the car that day from a used car lot and was insured (liability only) at the time of driving off the lot. The court paperwork also states the accident was my girlfriend's fault, but fault was never admitted and the police report states an entirely different scenario than what is called on the court documents.
