Domestic violence charges are very serious charges , you should hire a lawyer ASAP. Dropping of charges will be up to the prosecutor , but with the help of a criminal,defense attorney you stand a good chance of getting pre trial diversion anger manage etc with possibility of no record. Also your wife can take the privilege - not be forced to testify . Get a Lawyer!
Dropping the charges will be left up to the Assistant District Attorney (DA) who is handling the case, not your defense attorney, however, if you hire a good Criminal Defense Attorney who handles these types of cases and has a good working relationship with the Prosecution, the chances of getting what you are looking for may be more favorable to you.
Judges in Richmond County, as in many counties, do not "drop" domestic charges easily. With everything you have at stake , you need to hire a lawyer. My firm website is listed below. Either John Manton or Harold Jones can help you with your case. They are both former State Court prosecutors and have handled many of these types of cases.
Domestic violence charges are not handled lightly. Your wife can request that the charges be dropped, but it is ultimately the prosecutor's decision. Moreover, you should not suggest anything to your wife about dropping charges. This could result in you being charged with further crimes for influencing a witness. Moreover, you have been given some incorrect information about spousal privilege. The law has recently changed on spousal privilege. Before the change, a spouse could refuse to testify in a criminal case against another spouse as long as no child was involved in the crime. Now, the law has been changed and a spouse no longer has a testimonial privilege in domestic violence cases. You need to hire an attorney to handle this case for you.
