I'm not sure why you have a lawyer representing you on the criminal charge. Your interests in that case are represented by the prosecutor, whose job it is to handle his lawyer. If it is a criminal case, your lawyer would have no role in the case and couldn't participate at all.
I think your money would be better spent on a family lawyer for purposes of getting an interim order giving you and the kids the right to stay in the house (and requiring him to stay out unless invited).
