Assault and battery are both civil (lawsuit) and criminal.  The criminal case and civil case are separate matters and proceed independently.  You can be sued in the civil case even though the criminal case has not concluded.The standard of proof in a civil case is a preponderance of the evidence which means more likely than not.  This is a lesser standard of proof than in a criminal case which requires proof beyond a reasonable doubt.  Therefore, it is possible that you could be acquitted in the criminal case but still found liable in the civil case where the required standard of proof is less.
