Can You Change Your Judge in Arizona? Rule 10.2

Can You Change Your Judge in Arizona?

Once a criminal case is assigned to a judge, most defendants assume they are simply stuck with whoever they draw. In Arizona, that is not quite true. A change of judge in Arizona is a formal procedural right — and for one change, you do not have to prove anything at all. The catch is timing: the window to use it is measured in days, and it closes for good if you miss it. This guide explains the two ways to change a judge, exactly when the clock starts, and why the deadline is the whole ballgame.

This is a procedure, not a loophole, and it sits inside the broader Arizona criminal court process. Nothing here is about the qualities of any particular judge — the rules are neutral and available to both sides equally.

Yes — in most criminal cases, each side can change the assigned judge once without giving any reason. Arizona Rule of Criminal Procedure 10.2 calls this a change of judge “as a matter of right.” The rule text is direct: “Each side in a criminal case is entitled to one change of judge as a matter of right.” You exercise it by filing a document titled a Notice of Change of Judge that names the judge and includes an avowal that the request is made in good faith.

Two features make this right unusual. First, no allegation of bias or prejudice is required — this is often called a “peremptory” change. Second, it is essentially automatic: if the notice is timely and proper, the change happens. But the rule builds in real limits. A case is treated as having only two “sides,” and once a party has used its change of right, Rule 10.2(a)(3) says that party is not entitled to another one. It also does not apply to a remand for resentencing.

Peremptory Change vs. Change for Cause: What’s the Difference?

Arizona actually gives you two separate paths, governed by two separate rules, and they work very differently.

The first is the peremptory change under Rule 10.2 described above — one per side, no reason, strict short deadline. The second is a change of judge for cause under Arizona Rule of Criminal Procedure 10.1. That rule is not automatic and is not limited to one use. Instead, a party must actually show that “the assigned judge’s interest or prejudice would prevent a fair and impartial hearing or trial.” The motion has to be supported by an affidavit stating specific grounds, and a different judge holds a hearing and decides the question by a preponderance of the evidence.

In plain terms: the peremptory change is easy to get but you only get one and you must move fast; the for-cause change has no numerical limit but you have to prove genuine partiality, which is a high bar. Most defendants who change a judge do it through the peremptory route under Rule 10.2 precisely because it does not require proving anything about the judge.

What Is the Deadline to Ask for a Change of Judge?

This is where cases are won or lost. The peremptory right under Rule 10.2 must be exercised within a short window — and Arizona’s rule ties the clock to a specific triggering event, not to your feelings about the case. Under Rule 10.2(c), a party generally must file the Notice of Change of Judge no later than 10 days after the earliest applicable trigger.

One common trigger is the arraignment. If your case is assigned to a judge and you are given actual notice of that assignment at or before your arraignment, the 10-day clock starts then — which is one more reason to understand what happens at an arraignment in Arizona before you walk in. In other cases, the clock starts when you actually receive notice that the case has been assigned to a particular judge.

When Is Your Deadline to File a Change of Judge?

Because the trigger depends on how and when your case was assigned, the deadline is not one-size-fits-all. This table maps the common situations to the filing deadline set out in Rule 10.2(c). Every case is different, and local rules can adjust these timelines, so confirm your specific deadline with counsel.

What Happens After You File a Notice of Change of Judge?

The process is fast and administrative, not adversarial. Once a timely Notice of Change of Judge is filed, Rule 10.2(b)(3) directs the named judge to proceed no further in the case — other than entering any necessary temporary orders — until the matter is transferred. The case then goes to the presiding judge, who under Rule 10.2(d) must immediately reassign it to another judge. If all parties agree on an available judge, that agreement can be honored instead. For how the criminal bench is organized and how to find your assigned judge, see our Maricopa County Superior Court judges guide.

You do not choose your replacement judge. Reassignment is handled by the presiding judge or a designee, which keeps the process neutral. In a busy county, the mechanics of that reassignment run through the court’s calendar system; our guide to Maricopa County Superior Court explains how cases move through that structure. If there are multiple defendants, a notice filed by one defendant does not force a change of judge for the others — though it can lead to severance for trial.

How Can You Lose the Right to a Change of Judge?

Two ways: by running out the deadline, and by waiver. Under Rule 10.2(e), a party loses the peremptory right if it participates before that judge in any contested matter, in a proceeding under Rule 17 (change of plea), or in the beginning of trial. In other words, if you litigate something substantive in front of the judge first, you are generally treated as having accepted that judge.

That is why the change of judge decision has to be made early and deliberately. Waiting to “see how things go” with the assigned judge can quietly forfeit the right. The one significant exception is a remand for a new trial after a successful appeal: Rule 10.2(f) restores the peremptory right if it was not already used, and nothing from the first trial counts as a waiver.

Is Asking for a Change of Judge Just “Judge-Shopping”?

No — and it is important to be precise here. A peremptory change of judge is a right the Arizona Supreme Court built into the rules for both the defense and the prosecution. Using it is legitimate procedure. What the rule expressly prohibits is using it for an improper purpose, and Rule 10.2(b)(2) actually lists them: to cause delay, to obtain a severance, to interfere with a judge’s reasonable case-management practices, to remove a judge for reasons of race, gender, or religion, to use the rule against one judge in a blanket fashion, to get a more convenient location, or to gain leverage in plea bargaining or sentencing.

The notice itself requires a good-faith avowal, and for lawyers that avowal is made as an officer of the court. Courts and the state bar take abuse of the rule seriously. A responsible lawyer treats the change of judge as a considered strategic decision about the posture of the case — never as a way to disparage or “shop around” judges, which the rule forbids.

Does This Apply in Justice and Municipal Courts Too?

The Arizona Rules of Criminal Procedure govern criminal cases across Arizona’s courts, including justice courts and municipal (city) courts, so the concept of a change of judge is not limited to superior court felony cases. If you are facing a misdemeanor in a justice or city court, a change of judge may be available to you.

That said, the mechanics can differ. Many limited-jurisdiction courts have only one or a few judges, so a change means transfer to another judge or court rather than reassignment by a presiding judge down the hall, and some courts have their own local procedures and deadlines. This is exactly the kind of detail worth confirming with counsel or the specific court, rather than assuming the superior-court process applies identically.

How a Lawyer Helps With a Change of Judge in Arizona

The single most valuable thing a lawyer does here is protect the deadline. By the time many people think to ask whether they can change their judge, the 10-day window has either started without them noticing or already closed. A defense attorney who is watching the docket knows the moment a judge is assigned, calculates the correct trigger under Rule 10.2(c), and files a proper Notice of Change of Judge — with the required good-faith avowal — before the clock runs out.

Beyond the mechanics, the harder judgment is whether to use the one peremptory change at all. Because it can only be used once, spending it is a strategic decision that depends on the whole posture of the case, and it is not one to make casually or emotionally. If the concern is genuine partiality rather than strategy, counsel can evaluate whether a for-cause motion under Rule 10.1 is the better tool.

The criminal right comes from the Rules of Criminal Procedure, not a statute. On the civil side, the counterpart is statutory: A.R.S. § 12-409 lets a party in a civil superior court case seek a change of judge for cause by affidavit. The two tracks work differently, which is one more reason to have counsel who handles criminal matters specifically.
