Quick Answer

Yes. Under California Penal Code 261.5, sexual intercourse with anyone under 18 who is not your spouse is a crime, even when both participants are minors. Two 15-year-olds can each face charges for the same act. Because both parties are under 18, these cases are handled in juvenile court, and California has no Romeo and Juliet exception.

Key Takeaways

  • California’s age of consent is 18, and Penal Code 261.5 applies to any person, so two teenagers under 16 can both be charged over the same encounter.
  • Cases involving two minors are heard in juvenile delinquency court under Welfare and Institutions Code 602, where the focus is rehabilitation rather than punishment.
  • California has no Romeo and Juliet exemption, but when the age difference is three years or less, the offense is a misdemeanor as a matter of law.
  • A statutory rape case never carries automatic sex offender registration. A judge may only order registration under Penal Code 290.006 after making specific findings on the record.
  • Penalties climb steeply with age: an adult 21 or older who has intercourse with a minor under 16 faces up to four years in state prison and civil penalties of up to $25,000.

Statutory Rape and the Age of Consent in California

California sets the age of consent at 18, one of the strictest standards in the country. California Penal Code 261.5 defines unlawful sexual intercourse, commonly called statutory rape, as an act of sexual intercourse with a person who is not the spouse of the perpetrator, if that person is a minor. The statute defines a minor as anyone under 18 years of age.

Two details in that definition matter enormously for teenagers and their parents. First, the statute applies to any person, not just to adults. Nothing in the law limits prosecution to people over 18, and California courts have applied it to minors. Second, willingness is legally irrelevant. The offense is complete once intercourse occurs with someone under 18, regardless of who initiated the encounter or whether both participants agreed to it.

The only true exception written into the statute is marriage. Spouses are excluded from the definition of unlawful sexual intercourse. California has no fixed minimum age for marriage, but a minor can only marry with the consent of a parent or guardian plus a court order under Family Code sections 302 through 304, a process that includes a review by Family Court Services. In practice, this exception almost never applies to two teenagers under 16.

Can Both Teens Be Charged If Both Are Under 16?

Technically, yes. When two 15-year-olds have sexual intercourse, each of them has committed unlawful sexual intercourse with the other in the eyes of the law. Each participant is simultaneously a legal victim and a potential respondent. That result strikes many families as absurd, but it follows directly from how the statute is written, and California appellate courts have upheld delinquency findings against minors under this law.

In practice, prosecution is far from automatic. District attorneys have broad discretion, and many cases involving two similarly aged teenagers are never charged at all, particularly when the encounter was mutual, no other offense is alleged, and neither family pushes for charges. Discretion, however, is not immunity. Cases do reach prosecutors, often after a parent discovers the relationship, a school becomes involved, or a mandated reporter such as a doctor, nurse, or counselor is required to notify authorities.

When a case is filed against someone under 18, it does not go to adult criminal court. Under Welfare and Institutions Code 602, the juvenile delinquency court has jurisdiction over minors ages 12 through 17 who violate any law. Children under 12 cannot be brought into delinquency court at all except for a short list of serious violent offenses, and statutory rape is not on that list.

Why Consent Is Not a Defense When Both Parties Are Minors

California law treats everyone under 18 as legally incapable of consenting to sexual intercourse. This is a rule about legal capacity, not about what actually happened. Even if both teenagers say the encounter was completely mutual, that agreement has no legal effect on whether the offense occurred. The Legislature designed the rule this way to protect minors from exploitation and from consequences they may not be equipped to weigh.

That does not mean the facts are irrelevant. A genuinely mutual encounter between two teenagers close in age looks very different to a prosecutor, a probation officer, and a judge than a case involving pressure, manipulation, or a significant age gap. Mutuality frequently shapes the decision whether to file at all, and it influences how a juvenile case is resolved.

It is also important to keep statutory rape separate from forcible sex offenses. Penal Code 261.5 involves no allegation of force. If force, threats, or an incapacitated victim is alleged, prosecutors can file far more serious charges under Penal Code 261, which carry state prison terms and mandatory lifetime registration. Making sure a mutual teenage encounter is not mischaracterized as something more serious is one of the most important reasons to involve a defense lawyer early.

Does California Have a Romeo and Juliet Law?

No. Many states have Romeo and Juliet laws that exempt consensual sex between close-in-age teenagers from prosecution. California is not one of them, a point we cover in depth in our article on Romeo and Juliet laws in California. In California, every act of sexual intercourse with a minor is chargeable, no matter how close the two participants are in age.

What California has instead is a charging gradient built into the statute itself. Under Penal Code 261.5(b), when the age difference between the two participants is three years or less, the offense is a misdemeanor as a matter of law, not merely as an act of prosecutorial leniency. That is not an exemption. The conduct is still a crime. But it caps the severity of the charge for close-in-age cases.

For a 15-year-old with a 16-year-old partner, or a 15-year-old with a 17-year-old partner, the age gap falls within three years, so the conduct sits at the misdemeanor level, and because both participants are minors, any case would proceed in juvenile court rather than adult criminal court.

Penalties for Violating California’s Statutory Rape Law

Penalties under Penal Code 261.5 depend almost entirely on the age difference between the parties and the age of the defendant. The table below summarizes the criminal exposure in adult court.

Criminal penalties by age difference

Circumstances Classification Maximum penalty in adult court
Age gap of three years or less (PC 261.5(b)) Misdemeanor Up to 6 months in county jail and a fine of up to $1,000
Defendant more than three years older than the minor (PC 261.5(c)) Misdemeanor or felony (wobbler) Misdemeanor: up to 364 days in county jail. Felony: 16 months, 2 years, or 3 years under Penal Code 1170(h)
Defendant 21 or older and minor under 16 (PC 261.5(d)) Misdemeanor or felony (wobbler) Misdemeanor: up to 364 days in county jail. Felony: 2, 3, or 4 years in state prison

Note that the maximum sentence the statute itself allows is four years, for an adult 21 or older with a minor under 16. Higher figures sometimes quoted online belong to forcible rape charges under Penal Code 261, a different and far more serious offense.

Civil penalties for adult defendants

Separately from any criminal sentence, Penal Code 261.5(e) allows the district attorney to bring a civil action against an adult who engages in unlawful sexual intercourse with a minor. These civil penalties do not apply to minors.

Age relationship Maximum civil penalty
Minor less than two years younger than the adult $2,000
Minor at least two years younger than the adult $5,000
Minor at least three years younger than the adult $10,000
Adult 21 or older and minor under 16 $25,000

How Juvenile Court Handles a Case Between Two Minors

When both participants are under 16, the penalty tables above set the legal frame, but they are not what actually happens. Juvenile delinquency court operates on different principles from adult criminal court. Its stated purpose is rehabilitation and guidance, not punishment, and its outcomes are called dispositions rather than sentences. A typical case moves through these stages:

  1. Referral: police or a mandated reporter refers the matter to the county probation department, which screens the case.
  2. Intake decision: probation can close the case, resolve it informally with counseling or a program, or refer it to the district attorney.
  3. Petition: if the district attorney files a petition, the case goes before a juvenile court judge. There is no jury in juvenile court.
  4. Jurisdiction hearing: the judge decides whether the allegations are true, the juvenile equivalent of a trial.
  5. Disposition: if the petition is sustained, the judge chooses a disposition, which for an offense like this typically means informal supervision or probation with terms such as counseling, education programs, and community service.

Detention is rare in a case involving two similarly aged teenagers with no aggravating facts. The California courts’ juvenile delinquency self-help guide explains the process in more detail. Just as important, a sustained juvenile petition is not a criminal conviction, and under Welfare and Institutions Code 786 the court must seal the minor’s records once probation or supervision is completed satisfactorily, which protects future college, employment, and licensing applications.

Do You Have to Register as a Sex Offender?

Not automatically, at any age. Unlawful sexual intercourse under Penal Code 261.5 is not on the list of offenses in Penal Code 290 that require mandatory sex offender registration. This is one of the most persistent fears families bring to our office, and for this offense the fear is usually misplaced.

For adults, a judge retains narrow discretion under Penal Code 290.006 to order registration, but only after finding on the record that the offense was committed as a result of sexual compulsion or for purposes of sexual gratification, and stating the reasons. When that happens, the person is placed by default in tier one, the lowest level of California’s three-tier registry system created by Senate Bill 384. The California Department of Justice publishes a plain-language SB 384 registrant FAQ explaining the tiers.

For minors, the rule is even narrower. Juvenile adjudications trigger registration only for the specific offenses listed in Penal Code 290.008, and unlawful sexual intercourse is not among them. A juvenile statutory rape adjudication therefore does not lead to sex offender registration.

Defenses to a Statutory Rape Allegation

Attorney Sheny Gutierrez has defended clients in Orange County courtrooms for more than 15 years, including in her role as criminal defense attorney for the Mexican Consulate, and these cases are rarely as simple as an accusation makes them sound. Depending on the facts, defenses may include:

  • No sexual intercourse occurred. Penal Code 261.5 requires an act of sexual intercourse. Other conduct is not statutory rape, and accusations sometimes rest on assumption or rumor rather than evidence.
  • Reasonable, good-faith mistake of age. Since People v. Hernandez (1964), California has recognized a defense where the accused honestly and reasonably believed the other person was 18 or older, for example based on what they said or a fake ID. This defense matters most for adult defendants.
  • False accusation. These allegations can arise from angry parents, custody disputes, or social pressure, and the account can shift over time. A careful review of messages, witnesses, and timelines often tells a different story.
  • Marriage. Intercourse between spouses is excluded from the statute entirely.

In juvenile matters, the goal is often broader than contesting the petition: keeping the case at the informal level, negotiating a disposition focused on counseling rather than wardship, and making sure records are sealed when supervision ends.

Example Scenarios

Two 15-year-olds in a relationship

Two high school students, both 15, are in a relationship their parents know about. One parent learns the relationship has become sexual and calls the police. Legally, both teens have violated Penal Code 261.5(b). Realistically, the probation department is likely to handle the matter informally, with counseling and family involvement rather than a petition, and neither teen faces sex offender registration. If a petition is filed and sustained, records can be sealed after successful completion of supervision.

A 15-year-old and a 17-year-old

Because the age gap is under three years, the conduct sits at the misdemeanor level, and because the 17-year-old is still a minor, the case belongs in juvenile court. The 17-year-old is more exposed than a same-age partner would be, especially if there are aggravating facts, but the framework of informal resolution, probation, and record sealing still applies.

A 22-year-old and a 15-year-old

The picture changes completely. The defendant is an adult 21 or older, and the minor is under 16, so Penal Code 261.5(d) applies: a wobbler chargeable as a felony with up to four years in state prison, a civil penalty of up to $25,000, and the possibility of discretionary sex offender registration under Penal Code 290.006. The same act that juvenile court would treat as a counseling matter between two teenagers is a serious felony case for an adult.

Common Questions About Statutory Rape Between Minors

Can a person under 16 legally consent to sex in California?

No. The age of consent in California is 18. Anyone younger, including 16- and 17-year-olds, is legally incapable of consenting to sexual intercourse, no matter how willing they are in fact.

Can a 15-year-old and a 17-year-old legally be in a relationship?

Dating itself is legal. Sexual intercourse is not, even in a committed relationship, because both are under 18. Since the age gap is within three years, the offense level is a misdemeanor, and a case against the 17-year-old would be handled in juvenile court.

Does a Romeo and Juliet rule protect a 15-year-old and a 16-year-old?

No. California has no Romeo and Juliet exemption, so the conduct remains chargeable. The close age gap matters in two ways: it keeps the offense at the misdemeanor level under Penal Code 261.5(b), and it makes informal juvenile resolution far more likely.

How young can a child be charged?

Under Welfare and Institutions Code 602, juvenile court jurisdiction generally begins at age 12. A child under 12 cannot be brought into delinquency court except for a handful of serious violent offenses, and statutory rape is not one of them.

Will a juvenile case stay on my child’s record?

Not permanently, in most cases. A sustained juvenile petition is not a criminal conviction, and Welfare and Institutions Code 786 requires the court to seal the records once the minor satisfactorily completes probation or supervision.

What to Do If Police or Probation Contact Your Family

Most families first learn about an investigation through a phone call from a school resource officer, a detective, or a county probation intake officer asking to speak with their teenager. How you respond in that first week often shapes the entire case, because the decision that matters most, whether the matter is closed, handled informally, or filed as a petition, is made early.

  • Do not let your child give a statement, even an informal one. Minors have the same right to remain silent as adults, and statements made to reassure an officer are the most common way a closable case becomes a filed one.
  • Be careful with texts and social media. Messages between the two teens are usually the central evidence, and deleting them can create a far worse problem than the messages themselves.
  • Do not contact the other family to smooth things over. Well-intentioned apologies are routinely repeated to investigators as admissions.
  • Write down the timeline privately while it is fresh: how the relationship started, both birth dates, and who knew what. Age math down to the day can decide which subdivision of the statute applies.
  • Talk to a defense lawyer before the intake interview, not after. Counsel can often present context to probation that steers the case toward informal handling and, later, make sure sealing actually happens.

Parents are sometimes afraid that hiring a lawyer makes their child look guilty. In juvenile court, it signals the opposite: an engaged family, which is precisely what probation officers and judges say they want to see when they choose between formal and informal resolution.
