A criminal charge in Arizona can touch your freedom, your record, and your next step at work or home.


If this is your first arrest in Arizona, what happens next?

You are sitting in a holding room, still trying to understand what just happened. Your first case can feel bigger than the charge itself. In Arizona, the process moves fast, and the first 48 to 72 hours matter because they can shape bond, release, and what happens next.

After an arrest, Rule 4.1 of the Arizona Rules of Criminal Procedure requires an Initial Appearance within 24 hours. That is where a judge sets release conditions, which can include bond, own recognizance release, or pretrial detention. If you get a criminal defense attorney involved early, you give yourself a better chance to affect those first decisions instead of reacting after they are made.

In Arizona, misdemeanor cases are divided into Classes 1, 2, and 3 under ARS 13-707. A Class 1 misdemeanor can bring up to six months in county jail, and even a misdemeanor conviction can stay on your record unless it is later set aside under ARS 13-905 or sealed under ARS 13-911. That is why a first case is never just a small event.

If the charge is a DUI or another criminal matter, this is also when people start asking about license suspension, how long a DUI stays on your record, and what a DUI lawyer costs. Those questions are normal because the case reaches into daily life fast. A criminal defense lawyer arizona knows the court deadlines, the local process, and how to push back before the State locks in its version of the facts.


When does a repeat or aggravated case make Arizona more serious?

You may be looking at a second stop, a prior case, or an allegation that changes the stakes overnight. In Arizona, repeat and aggravated allegations can change how the court sees the charge and how much punishment is on the table. That is where a criminal defense attorney has to look closely at priors, enhancements, and whether the State can prove what it says it can prove.

Arizona felonies are divided into Classes 1 through 6 under ARS 13-702 and ARS 13-703. For repetitive offenders, the sentencing picture changes again, and a dangerous designation under ARS 13-704 can change exposure as well. A Class 6 felony may, in some cases, be designated as a misdemeanor at sentencing under ARS 13-604. Those details matter because the label on the charge is not always the last word.

When people hear aggravated DUI, they often think only about the word aggravated. The real issue is what facts and prior events the State uses to support that charge. The same is true in other criminal defense cases. A repeat accusation can bring jail time, tougher bargaining, and more pressure from the prosecutor, but the defense can still challenge the stop, the search, the proof, and the way the State uses prior history.

That is why a criminal defense lawyer arizona looks at the whole case, not just the headline. If the State relies on a prior, a designation, or a special allegation, the defense has room to contest it. The earlier you do that, the more options you keep alive.


Which Arizona court will hear your case?

You might assume every case goes to one courthouse, but in Arizona the court depends on the charge. For a felony, the case goes to Superior Court. For a misdemeanor, it usually starts in city or justice court. That split shapes the pace, the hearing schedule, and the people who will decide the next step.

Maricopa County Superior Court at 201 W Jefferson St in Phoenix handles felony cases. Misdemeanor cases are heard in the county’s justice courts and municipal courts, including facilities in Mesa at 222 E Javelina Ave, Surprise at 14264 W Tierra Buena Ln, and North Phoenix at 18380 N 40th St. Mohave County Superior Court at 415 E Spring St in Kingman handles felony cases there. If your arrest happened in one county and the court is in another, the courthouse you walk into still matters because local process matters.

Oliverson Law handles criminal defense cases throughout Arizona from Tempe, and the firm appears regularly in Maricopa County and Mohave County. Derek Oliverson also began his legal career as a prosecutor in Mohave County, so he knows the local rhythm from the inside. That kind of background can help you understand what the court expects before you ever stand in front of a judge.

If you are trying to figure out whether your case belongs in justice court, municipal court, or Superior Court, that question should be answered early. A criminal defense attorney arizona can help you read the venue, the level of charge, and the practical pressure each court creates.


What punishment can Arizona criminal cases bring?

You are staring at a charge sheet and trying to make sense of what it could cost you. In Arizona, the penalty depends on the class of the offense, whether it is a misdemeanor or felony, and whether the State adds prior or dangerous allegations. The punishment is not the same in every case.

A Class 1 misdemeanor under ARS 13-707 can result in up to six months in county jail. Class 2 and Class 3 misdemeanors carry progressively shorter maximum jail terms. Even when the jail time is shorter, the record can still follow you unless the case is later set aside under ARS 13-905 or sealed under ARS 13-911.

Felonies are divided into Classes 1 through 6 under ARS 13-702 and ARS 13-703. Class 1 is the most serious and Class 6 is the least serious. In some cases, a Class 6 felony can be designated as a misdemeanor at sentencing under ARS 13-604. But if the offense is designated dangerous under ARS 13-704 or if repetitive offender rules apply, the stakes can rise fast.

This is also where people ask about license suspension, how long a DUI stays on your record, aggravated DUI, and jail time. Those questions are all connected to the same reality: a criminal case can affect your freedom, your record, and your future long after court is over. A criminal defense lawyer should look at the charge, the penalties, and the ways to reduce the damage before the State gets too far ahead.


How does a strong Arizona defense get built?

You are in the middle of a case and every police report seems to point the same direction. A real defense does not start with fear. It starts with questions. Was the stop lawful? Can the State prove every element? Is there a defense that fits the facts? What outcome helps you most in the long run?

Many Arizona cases turn on Fourth Amendment issues. Traffic stops without reasonable suspicion, searches beyond the scope of consent, and warrantless home entries without exigent circumstances can create suppression issues under ARS 13-3925 and the Fourth Amendment. If the evidence should not have been used, the case can change fast.

The defense also looks at the chain of custody, lab testing, officer credibility, body camera video, and witness reliability. The State has to prove every element beyond a reasonable doubt. If one element fails, the prosecution fails. That is true in DUI, aggravated DUI, drug crimes, theft, assault, weapons cases, probation violation matters, and the rest of criminal defense.

Arizona also recognizes self-defense under ARS 13-404 and defense of a third person under ARS 13-406, along with other defenses like necessity, duress, and mistake of fact. When the facts support it, a criminal defense attorney brings those issues up early instead of waiting for trial. That is how a criminal defense attorney arizona turns pressure back toward the State.


What should you do tonight after an arrest in Arizona?

You are home or still waiting to be released, and your mind keeps going back to the same moment. Tonight is about keeping the case from getting worse. Do not talk about the facts with police or anyone else who could become a witness. Do not guess about what the State already knows. Get the paper and note the court name, the charge, and the next date if you have one.

Arizona’s process moves quickly, and the first choices can affect bond, release, and the shape of the whole case. If you already know the case may involve DUI, aggravated DUI, or another criminal charge, call before the court date if you can. Having a criminal defense attorney in place before the Initial Appearance can matter because release conditions are often set there.

People also ask what a DUI lawyer costs, how long a DUI stays on your record, and whether license suspension can be fought. Those are fair questions, but the answer depends on the charge and the facts. The best first step is to get advice from a lawyer who handles criminal defense every day and knows Arizona courts, Arizona statutes, and the local process.

Derek Oliverson and David Tangren both work on these cases with a trial-ready mindset. If you want help now, Oliverson Law offers a free case evaluation at (480) 582-3637. Tonight, your job is simple: get help, stay quiet, and keep every option open.
