Initially, you should plead "not guilty" and then talk with a local attorney. That attorney will fully analyze your case, investigate, negotiate with the prosecutor and advise you about the best course of action.
You need to be very careful before you plead guilty to a Domestic Battery charge. Even though it is only a misdemeanor, it carries very serious consequences. For example, under Federal law, you can never own or be in possession of a firearm if you plead or are found guilty of this charge.
As the other attorney said, you need to speak to a good criminal attorney. If you need a recommendation for an attorney in NW Arkansas, give me a call. I previously practiced in that area and can give you some names.
