What the age of consent actually is

Few areas of Arizona law cause more confusion, or carry higher stakes, than the age of consent. People often assume the line is 16, or that a young person’s willingness settles the question. Neither is correct. This guide explains what the law says, how the charge changes with the alleged victim’s age, and the defenses that exist. It is written for parents, young adults, and anyone facing an accusation who needs clear information. It is meant to complement, not repeat, our detailed Phoenix sex crimes defense pages.

The age of consent in Arizona is 18. That means a person under 18 is not legally able to agree to sexual activity, no matter how mature they are or how willingly they participated. The governing law is A.R.S. 13-1405, titled sexual conduct with a minor. It makes it a crime to intentionally or knowingly engage in sexual intercourse or oral sexual contact with any person who is under 18 years of age.

Many people call this “statutory rape,” but that is not the term Arizona uses. The state charges it as sexual conduct with a minor, and the label matters because the statute, not the common phrase, defines the elements and the punishment. The central point is simple: because the law treats anyone under 18 as unable to give legally valid consent, the minor’s agreement is not a defense. The state does not have to prove force or lack of consent, only the age and the conduct.

How the charge changes with the minor’s age

Arizona does not treat every case the same. The felony class, and the sentence that follows, turns heavily on how old the alleged victim was and on the relationship between the two people. The younger the child, the more severe the charge. The table below breaks down how A.R.S. 13-1405 sorts these cases.

What a “position of trust” means and why it escalates the charge

The phrase “position of trust” is one of the most important, and least understood, parts of this law. When a defendant charged with sexual conduct involving a 15, 16, or 17 year old held a position of trust over that minor, the offense is not a class 6 felony. It becomes a class 2 felony, the same level as a case involving a much younger child.

Arizona defines a position of trust broadly. It generally covers a parent, stepparent, foster parent, guardian, or anyone acting in loco parentis, as well as people whose role gives them authority or a caretaking relationship over the minor, such as a teacher, coach, clergy member, or someone entrusted with the child’s supervision. The theory is that these relationships carry an inherent power imbalance, so the law punishes an abuse of that authority far more harshly than an offense between people with no such connection.

The practical effect is enormous. Two otherwise similar cases involving a 17 year old can carry radically different exposure depending on whether the state can prove a position of trust. Because that single element can raise the stakes from a probation-eligible class 6 felony to a class 2 felony with mandatory prison, it is frequently one of the most contested issues in the case.

Is a genuine mistake about the minor’s age a defense?

Usually not, and this surprises people. For the most serious cases, those involving a child under 15, Arizona treats the offense as effectively strict liability on age. A sincere belief that the person was an adult, even a reasonable one, is not a defense. The state does not have to prove the defendant knew the minor’s real age.

There is a narrow, statute-specific exception. Under A.R.S. 13-1407, subsection B, Arizona allows a limited defense where the alleged victim was 15, 16, or 17 and the defendant did not know and could not reasonably have known the minor’s age. This is a fact-intensive defense, not an easy out, and it does not apply to the youngest victims at all. Whether it is even available depends on the specific facts, which is exactly the kind of question a defense lawyer evaluates early.

The close-in-age (Romeo and Juliet) exception

Arizona does recognize that not every case involves an adult and a child. A.R.S. 13-1407 also contains a close-in-age defense, often called the Romeo and Juliet exception. In general terms, it can apply where the alleged victim is 15, 16, or 17, the defendant is under 19 or still attending high school, the two are no more than 24 months apart in age, and the conduct was consensual.

The window is deliberately narrow, and the details decide whether it applies. Because this exception has its own conditions and traps, we cover it in depth in a separate guide on the Romeo and Juliet law in Arizona. If the ages in your situation are close, that is one of the first things a defense lawyer will look at.

Registration and the consequences that outlast the sentence

A conviction for sexual conduct with a minor reaches far beyond a prison term. Many of these convictions carry mandatory sex offender registration under Arizona law, a status that can follow a person for decades and shape where they can live, work, and go. Registration is not a footnote. For many clients it is the single consequence they fear most, because it can persist long after any sentence is complete.

The direct penalties are severe on their own. Cases involving a child under 15 fall under the Dangerous Crimes Against Children scheme, which imposes long, mandatory prison terms and strips away the possibility of probation for the most serious counts. Position-of-trust class 2 felonies likewise remove much of the sentencing flexibility a court would otherwise have. Add the lasting collateral effects on employment, housing, professional licenses, and immigration status, and the true weight of one of these convictions comes into focus. This is why treating the charge as anything less than a full crisis is a mistake.

Common defenses to age of consent charges

An accusation is not a conviction, and these cases are often far more contestable than a frightened client assumes. The right defense depends entirely on the facts, but several recurring angles come up in Arizona courts. Our overview of the top sex crime defenses in Phoenix goes deeper, and the following are among the most common.

• The close-in-age defense. Where the ages fit the narrow statutory window under A.R.S. 13-1407, this can be a complete defense to the charge.
• Factual disputes and false allegations. Not every accusation is true. Cases can arise from a bitter custody fight, a breakup, jealousy, or pressure on a young person to say something that did not happen. Timelines, messages, and inconsistencies matter.
• Unlawful interrogation. If police questioned an accused person without proper warnings, ignored a request for a lawyer, or used coercive tactics, statements they obtained may be challenged and potentially suppressed.
• Challenging the state’s evidence. The prosecution must prove every element beyond a reasonable doubt, including the conduct itself and, where it applies, the position of trust or the age gap that raises the class. Weak proof on any element is an opening.
• Disputing a position of trust. Because that single element can turn a class 6 felony into a class 2, whether it truly existed is frequently worth fighting.

Why these cases demand a lawyer immediately

Sexual conduct with a minor is among the most serious charges Arizona recognizes, both in how it is punished and in how it can define a person’s life. The stakes, mandatory prison, lifelong registration, and permanent collateral damage, leave no room for a wait-and-see approach. Just as important, the earliest stage of a case, often before charges are even filed, is when a skilled defense can do the most, by protecting your rights during questioning and shaping the investigation.

If you or your child is under investigation or already charged, the most valuable things you can do are stay silent with police and speak with a defense attorney right away.

Every case is different, and no lawyer can promise an outcome, but getting experienced counsel involved early is how you preserve your options.
