Can you mix criminal case with a civil case in Nevada

The general rule is that an individual's conduct may give rise to both criminal and civil liability.  Imagine that you punched someone in the nose.  You could be prosecuted by the state for assault, and you could be sued in the civil court for  personal injury.  With respect to your situation, some of the facts that you have provided do not make complete sense.  For example, if you accepted a plea, then you would have had to waive your rights to appeal.  Therefore, it is unclear what, if any, pending criminal matter you have.  Moreover, if you have been convicted, that fact can be used against you in the civil court, which generally has a lower burden of proof when compared to the criminal area.  In any event, with respect to your specific question, what you should do is to discuss this matter with the attorney who already represents you.  He/she is truly in the best position to advise you with respect to this matter.  Good luck.
