Key Takeaways

• Initial Appearance Within 24 Hours: After arrest, you must appear before a judge within 24 hours for bail determination and advisement of charges.
• Grand Jury or Preliminary Hearing: For felonies, the prosecution must establish probable cause through a grand jury indictment or preliminary hearing within 10 days (in custody) or 20 days (out of custody).
• Your Attorney Is Critical at Every Stage: From challenging probable cause to filing pretrial motions, negotiating pleas, and preparing for trial, your attorney’s involvement at each step shapes the outcome.

Stage 1: Arrest and Booking

The criminal process begins with an arrest based on probable cause or a warrant. During booking, you are photographed, fingerprinted, and your personal property is inventoried. You have the right to remain silent and request an attorney immediately. Do not discuss your case with anyone except your lawyer.

Stage 2: Initial Appearance

Within 24 hours of arrest, a judge conducts an initial appearance where you are informed of the charges, advised of your rights, and bail is set. Your attorney can argue for lower bail or release on your own recognizance based on your ties to the community, employment, criminal history, and flight risk.

Stage 3: Preliminary Hearing or Grand Jury

For felonies, the prosecution must establish probable cause. This happens through either a preliminary hearing (where your attorney can cross-examine witnesses) or a grand jury proceeding (where only the prosecution presents evidence). Your attorney’s strategy at this stage can sometimes result in charges being reduced or dismissed.

Stage 4: Arraignment

At arraignment, you formally enter a plea — guilty, not guilty, or no contest. Most defendants plead not guilty at this stage to preserve all options. Your attorney will advise you on the strongest approach based on the evidence and circumstances.

Stage 5: Pretrial Motions and Discovery

This is where much of the defense work happens. Your attorney reviews all evidence (discovery), files motions to suppress illegally obtained evidence, challenges witness identifications, and prepares the defense strategy. Many cases are won or lost at this stage — before trial ever begins.

Stage 6: Trial or Plea

If a favorable plea agreement cannot be reached, the case proceeds to trial. You have the right to a jury trial for any charge carrying more than 6 months imprisonment. At trial, the prosecution must prove every element beyond a reasonable doubt. Your attorney cross-examines witnesses, presents defense evidence, and argues to the jury.

Stage 7: Sentencing

If convicted, sentencing follows. Arizona uses a structured sentencing framework with presumptive, mitigated, and aggravated ranges for each felony class. Your attorney presents mitigating factors to argue for the lowest possible sentence.

Frequently Asked Questions

How long does the criminal process take in Arizona? It varies widely. Misdemeanors may resolve in weeks to months. Felonies typically take 3-12 months from arrest to resolution. Complex cases can take longer. Your right to a speedy trial ensures the process doesn’t drag on indefinitely.

Can charges be dropped before trial? Yes. The prosecution can dismiss charges at any point if evidence is insufficient, if key evidence is suppressed, or if new information emerges. Your attorney’s pretrial motions and negotiations are designed to create these opportunities.

What happens if I miss a court date? A bench warrant is issued for your arrest. Additional charges of failure to appear may be filed. If you realize you’ve missed a date, contact your attorney immediately — there may be options to resolve the warrant before you are arrested.

Should I accept a plea deal? This depends entirely on the strength of the evidence, the charges, and the potential penalties at trial. Your attorney will advise you on whether a plea offer is favorable compared to the realistic outcomes at trial. Never accept a plea without legal counsel.
