In general, your first court date is your arraignment, and what you should do is to plead "Not guilty" when the charges are first read out and you are asked how you plead. As you have an attorney, what happens from there will be depend on what you and your attorney got to discuss before the case was called.
Every defendant has only two broad choices. You can take a plea offer, or you can choose to fight the case. This is a domestic matter. I don't know the status of your relationship. But if your husband is not really looking to prosecute you, even though the prosecutor has filed these charges, you probably would want to fight the case long enough for the state to consider dismissing the case. Though they don't like to do that on a DV case, and they don't do it quickly, if a husband and wife want to work out their situation on their own and the complainant enlists the aid of the defense lawyer to help him convince the DA to drop, usually something very favorable to the defendant (though not always a dismissal) can eventually be worked out.
So tomorrow's conversation with your lawyer is very important. He will be able to see the charges and conference your case with the prosecutor. He will share the results of that conference with you and probably be able to tell you what sort of a plea the prosecutor has in mind. He'll also tell you the good and bad points of your case, and the good and bad sides of any plea agreement
so tthat you will be prepared for any decision you have to make in court.
The thing that you can do to protect yourself it to make your lawyer aware of any fact you believe he needs to know to best handle your case, and -- if you think that you and your husband are going to forgive each other -- not to jump too quickly at anything that will give you a criminal record
, just to get this case behind you.
