This is a question that comes up more often than many people realize, especially for parents and teenagers in Los Angeles. A lot of people assume that if two minors are close in age and the relationship is consensual, there is no legal issue. California law is not that simple. Under California Penal Code section 261.5, unlawful sexual intercourse involves sexual intercourse with a person under 18 who is not the spouse of the other person. The statute defines a minor as someone under 18.
So, is it illegal for two minors to have sex in California? In many situations, the legal answer is yes. California does not create a blanket exception just because both people are under 18 or because they are dating. If both individuals are minors, the case may still fall under statutory rape law, although the age difference matters a great deal when it comes to how the case may be charged and handled.
California does not have a true “Romeo and Juliet” exception
One of the biggest misconceptions is that California has a full “Romeo and Juliet” law that makes consensual sex between minors automatically legal if they are close in age. That is not exactly how the law works. Penal Code Section 261.5(b) states that when the minor is not more than three years older or younger than the other person, the offense is still a misdemeanor. In other words, close age does not necessarily make the conduct legal. It may reduce the severity of the charge, but it does not erase the issue altogether.
Age difference still matters
The age gap becomes more important as the difference between the two people increases. Under Penal Code section 261.5(c), if one person is more than three years older than the minor, the offense can be charged as either a misdemeanor or a felony. And under section 261.5(d), if a person is 21 or older and the minor is under 16, the penalties become significantly more serious. That means not every underage relationship is treated the same way under California law. Prosecutors look closely at age, facts, communications, and the surrounding circumstances.
What happens if both people are under 18?
If both parties are minors, the case will usually be handled in juvenile court rather than adult criminal court, because California law generally places minors between ages 12 and 17 who violate criminal laws within juvenile court jurisdiction. That does not mean the case is harmless. A juvenile petition can still have serious consequences, including court supervision, probation terms, counseling requirements, restrictions on school or social activity, and long-term reputational harm. Even when a case does not end in custody time, the process itself can be stressful and damaging for the child and the family.
Consent does not solve the problem
Another point that causes confusion is consent. Families often say, “It was consensual,” as if that ends the issue. But under California law, a person under 18 is considered a minor for purposes of unlawful sexual intercourse. That means consent, by itself, does not automatically prevent the government from pursuing a case. In real life, of course, consent still matters to the facts, to charging decisions, and to how a defense lawyer evaluates the case. But legally, consent alone is not always a complete answer.
Why these cases need careful handling in Los Angeles
In Los Angeles, allegations involving minors can quickly become more complicated than families expect. What starts as a teenage relationship can turn into a police investigation after a parent complaint, a school report, or digital evidence such as text messages and social media. Once law enforcement gets involved, the stakes can rise fast. Early legal intervention can make a major difference in protecting a young person’s future, limiting statements to police, and presenting the full context before charges gain momentum.
Speak with a Los Angeles criminal defense lawyer
If your son, daughter, or family member is being investigated for unlawful sexual intercourse involving a minor, do not assume the matter will simply go away because both individuals were under 18. These cases are highly fact-specific, and the details matter. An experienced Los Angeles criminal defense attorney can evaluate the ages involved, the evidence, the nature of the relationship, and whether the case belongs in juvenile court or exposes the minor to something more serious.
