Should You Take a Plea Deal or Go to Trial in Arizona?

By the Law Office of Robert P. Jarvis | Mesa, Arizona Criminal Defense

It is one of the most consequential decisions a person facing criminal charges will ever make — and it is almost always made under pressure, with incomplete information, and on a timeline set by someone else.

Should you accept the plea deal the prosecutor is offering? Or should you take your case to trial?

There is no universal answer. Anyone who tells you there is — including an attorney who hasn’t fully reviewed your case — is giving you false certainty. But there is a framework for thinking through the decision clearly, and there are specific factors that consistently point toward one choice or the other. Understanding that framework is what allows you to make the decision with your eyes open rather than from fear or desperation.

Here is an honest breakdown of how this decision actually works in Arizona — and what every defendant in Maricopa County should understand before making it.

What a Plea Deal Actually Is

A plea agreement is a negotiated resolution between the defendant and the prosecutor in which the defendant agrees to plead guilty — typically to a reduced charge, a lesser number of charges, or with a sentencing recommendation — in exchange for the prosecutor not pursuing the full extent of the charges or sentencing available.

In Arizona, plea deals are offered by the Maricopa County Attorney’s Office (for state charges) or by federal prosecutors (for federal charges). The deal is not offered by the judge, and the judge is not bound by the sentencing recommendation in the agreement — though in practice judges accept plea agreements in the vast majority of cases.

What a plea deal is not: it is not an admission that you have no defense. It is not a sign of weakness. It is a calculation — one that weighs the realistic probability of conviction, the likely sentence if convicted at trial, and the certainty and scope of the resolution being offered.

That calculation deserves serious attention in every case.

What Going to Trial Actually Means

Exercising your constitutional right to a jury trial means the prosecution must prove every element of every charge against you beyond a reasonable doubt — the highest evidentiary standard in American law. You are presumed innocent. The burden never shifts to you.

In Arizona, most felony cases are tried before a jury of eight people (twelve for capital cases). Both sides present evidence, examine and cross-examine witnesses, and make arguments. The jury deliberates and reaches a verdict. If even one juror holds out — a hung jury — the case does not result in a conviction, and the prosecutor must decide whether to retry.

Going to trial means:

• Challenging the prosecution’s evidence directly
• Holding law enforcement and witnesses accountable under oath
• Giving the jury the opportunity to hear your side completely
• Maintaining the possibility of a full acquittal — not guilty on all charges

It also means:

• A longer process — months to over a year in some Maricopa County cases
• Higher legal costs
• Greater uncertainty about outcome
• The possibility of conviction on all charges — and in some cases, a harsher sentence than the plea offer

The Factors That Should Drive the Decision

1. The Strength of the Evidence Against You

This is the single most important factor in the analysis. Before any other consideration, your attorney should give you an honest, unflinching assessment of the prosecution’s evidence — not a pep talk, not a doom scenario, but a realistic read of what they have and how strong it is.

Questions to ask:

• Is the evidence physical (DNA, fingerprints, video, chemical test results) or testimonial (witness accounts that can be challenged on cross)?
• Was the evidence obtained lawfully, or is there a viable suppression motion?
• Are there inconsistencies in the police reports or witness statements?
• Does the physical evidence actually place you at the scene or connect you to the alleged conduct, or does it require inferences?

Weak evidence — particularly evidence that depends on the credibility of a single witness, that was gathered in a constitutionally questionable search, or that is circumstantial and requires multiple inferential leaps — argues for trial. Strong, clean, corroborated physical evidence argues more seriously for evaluating the plea.

2. The Sentence Differential

The gap between what the plea offers and what a conviction at trial would bring is called the trial penalty — and it is real. Prosecutors routinely offer significantly reduced sentences in exchange for guilty pleas, and judges in Arizona can and do sentence above plea recommendations when a defendant is convicted at trial.

The question is not just whether the plea is better than the worst case. The question is whether the plea is better than the realistic expected outcome at trial — accounting for the actual probability of conviction.

If the plea offers 18 months probation and the realistic trial outcome is 2 years probation, the difference may not be worth the uncertainty and cost of trial. If the plea offers 3 years in prison and the realistic trial outcome — given viable defenses — is acquittal or a hung jury, the calculus shifts dramatically.

Your attorney should walk you through this analysis with specific numbers, not vague assurances.

3. Whether Suppression Motions Could Change the Case

One of the most powerful tools in a criminal defense attorney’s arsenal is the motion to suppress — a pretrial motion arguing that evidence was obtained in violation of your constitutional rights and therefore cannot be used against you at trial.

If the drugs were found during an unlawful traffic stop, if the confession was obtained without proper Miranda warnings, if the search warrant was overbroad or unsupported — successful suppression of that evidence can transform a strong prosecution case into a weak one or eliminate it entirely.

Before evaluating a plea, your attorney should have identified every suppression issue in the case and filed or prepared to file the relevant motions. A plea accepted before suppression issues are fully explored is a plea accepted before you know what case the prosecution actually has.

4. The Charge and Its Collateral Consequences

Some charges carry collateral consequences so severe that avoiding them — even at the cost of a harder fight — is worth the effort.

A felony conviction carries permanent consequences: loss of firearms rights, employment barriers, housing barriers, loss of voting rights during sentence, professional licensing disqualification, and in non-citizen cases, potential deportation.

A domestic violence designation — even on a misdemeanor — permanently eliminates federal firearms rights under the Lautenberg Amendment.

A sex offense registration requirement — attached to certain pleas as a condition — follows a person for decades and in some cases for life.

When a plea deal still results in these collateral consequences, the calculus changes. The willingness to fight harder for a better resolution — or for acquittal — increases proportionally with how permanent and severe those consequences are.

5. Your Personal Circumstances and Risk Tolerance

Two people can face identical charges, identical evidence, and identical plea offers — and make opposite decisions that are both correct for their circumstances.

A person with young children, a steady job, and no prior record may rationally prioritize certainty over the possibility of a better outcome at trial. The disruption of a lengthy trial process, the risk of a worse sentence, and the value of getting past the situation and moving forward may outweigh the appeal of fighting.

A person facing a felony that would cost them their career, their professional license, or their immigration status may rationally choose to fight — because the plea offer’s consequences are nearly as devastating as conviction, and the uncertainty of trial is worth bearing for a chance at acquittal.

Neither calculation is wrong. Both are honest assessments of individual circumstances. What is wrong is making the decision based on fear, exhaustion, or the sense that fighting is futile — without ever receiving a clear-eyed analysis of the actual odds.

6. Whether You Have Viable Defenses at Trial

This is where the attorney’s work becomes most critical. A viable defense is not just a story — it is a theory supported by evidence, capable of raising reasonable doubt in the minds of jurors, and delivered by an attorney who is genuinely prepared to try the case.

Common viable defenses in Arizona criminal cases include:

• Suppression of key evidence based on Fourth or Fifth Amendment violations
• Misidentification — challenging eyewitness identification through cross-examination, expert testimony on memory reliability, or alibi evidence
• Consent — in cases involving property crimes, trespass, or certain assault allegations
• Self-defense or defense of others — Arizona has strong self-defense laws under ARS § 13-404 and § 13-405
• Lack of intent or knowledge — the prosecution must prove the required mental state for most offenses, and this can often be genuinely disputed
• Credibility attacks on the prosecution’s key witnesses — prior inconsistent statements, bias, incentivized testimony from informants

The existence of one or more viable defenses that a skilled attorney can develop and present is one of the strongest arguments for trial.

What Prosecutors Count On — And How It Affects Plea Offers

Understanding why prosecutors offer plea deals helps you evaluate them more clearly.

Prosecutors in Maricopa County handle large caseloads. They cannot try every case. Plea deals exist because the system depends on most cases resolving short of trial — and because prosecutors, like defense attorneys, assess risk. A plea offer reflects the prosecutor’s own evaluation of their case, including the weaknesses they see and how confident they are in their evidence.

A generous plea offer on a serious charge is sometimes a signal that the prosecution’s case has problems they don’t want exposed at trial. A stingy offer on a charge with overwhelming evidence may simply reflect that the prosecution knows they will win.

Your attorney’s job is to read the offer in that context — not just as a number on paper, but as a data point about how the prosecution views their own case.

The One Thing That Should Never Drive the Decision

Fear.

More defendants in Arizona plead guilty to charges they could have fought — and won — because they were afraid of the process, afraid of the uncertainty, afraid of what might happen if they lost, or simply exhausted and wanting it over.

That fear is understandable. A criminal charge is one of the most stressful experiences a person can face. The pressure is real. But fear-based decisions in the criminal justice system tend to produce outcomes that defendants regret for the rest of their lives — particularly when the plea involved a felony conviction or collateral consequences that only became apparent later.

The antidote to fear-based decision-making is information. A detailed, honest analysis of your case from an attorney who has tried cases in Maricopa County, who knows the evidence, who has identified the defenses, and who will tell you the truth — even when the truth is uncomfortable — is what allows you to make this decision well.
