Most Courts have a domestic violence advocate who can interview you. If you experienced dv, they will help you fill out and file a dv petition. If your case is found to be valid, you can get a protection order to keep the abuser away. You might also check with your local police, since some cases indicate that a crime (like assault, for example) has taken place. If the police investigate and find that a dv crime has been committed, they will refer the case to the County Prosecutor for review. If the abuser is found to be guilty (by a guilty plea or a jury finding of guilty) he will go to jail. You can also check around for local dv groups or counselors; they can refer you to the proper authorities.
