Frequently Asked Questions
Important Information
Maricopa County processes approximately 35,000 DUI arrests annually, making it one of the busiest DUI court systems in the country. Direct solicitation by bail agents or attorneys at the jail or court is strictly prohibited by Arizona law (ARS § 20-340.03).
If Phoenix PD made the arrest, the case goes to Phoenix Municipal Court. If it was the Sheriff's Office or DPS, it goes to whichever of the county's 26 Justice Court precincts covers where the stop happened. Confusing the two is one of the most common early missteps in a Maricopa County DUI case.
The Court Structure
Maricopa County's Superior Court, the fourth-largest trial court system in the country, handles felony DUI exclusively, run out of the Central Court Building (201 W Jefferson St) and the South Court Tower (175 W Madison St) downtown, with Regional Court Centers in Mesa, Surprise, and north Phoenix handling earlier stages closer to the arrest location. Superior Court judges are appointed through merit selection, not elected, and face only periodic yes/no retention votes rather than campaigns.
Misdemeanor DUI, the vast majority of cases, goes to one of the county's Justice Courts, each presided over by an elected Justice of the Peace serving a 4-year term. As of 2024, four of these courts were operating above capacity, and the county has authorized a 27th Justice Court to open January 1, 2027, with precinct lines redrawn to rebalance the West Valley's rapid growth. One renaming worth knowing: the "Downtown Justice Court" at 620 W. Jackson St became "El Centro Justice Court" to stop people from queuing at the wrong precinct window inside the same building, which also houses Encanto, South Mountain, and West McDowell.
From Citation to Arraignment
Most misdemeanor DUI stops end in a citation rather than custodial booking; the officer issues an Arizona Traffic Ticket and Complaint listing the specific Justice Court and an arraignment date, typically 30 to 60 days out to allow time for BAC lab results. Entering a not-guilty plea at arraignment isn't a claim of innocence so much as a procedural move that preserves your right to discovery; some Justices of the Peace allow counsel to waive your physical presence and file the plea in writing, though others require you to appear in person to impose specific release conditions.
A pretrial conference usually follows 30 to 45 days later, where the defense reviews the police report, body camera footage, and toxicology results, and negotiates with the prosecutor. Given lab backlogs and case volume, it's routine for this phase to be continued more than once, stretching the whole process to 3 to 6 months before resolution.
Felony DUI
Aggravated DUI, meaning a suspended license, a third offense within 84 months, a minor in the car, or driving without a required interlock, moves to Superior Court. The Maricopa County Attorney's Office can initiate a case either through a direct complaint (with a preliminary hearing in Justice Court to establish probable cause) or a grand jury indictment, which skips that hearing entirely. Regional Court Centers run "Early Disposition Court" for many felonies, offering an immediate plea that can be withdrawn if you don't take it before the case moves to a full trial division downtown.
Diversion Is Mostly Off the Table
The County Attorney's Office policy explicitly excludes standard DUI offenses from its diversion program, meaning there's no charge-dismissal-for-completion track the way some other charges get. The narrow exception is Veterans Treatment Court, available to veterans whose conduct is materially connected to service-related trauma, with proof of service and a diagnosis required. A separate, non-dismissal DUI Court exists for high-risk repeat offenders: it's a post-adjudication track requiring a guilty plea, with intensive treatment, frequent testing, and weekly court appearances in exchange for reduced jail time.
