If you are charged with a crime in a district, municipal or superior court, your case will likely take at least three to six months to resolve. Some last as long as eight to twelve months. Defendants are required to attend an arraignment hearing and then a series of pre-trial hearings. Most hearings are spread out once a month. If the defendant is placed on probation, the case will remain open (usually) one to five years. A defendant can be summoned to attend a review hearing at any time while on probation.
