Romeo and Juliet laws are close-in-age exemptions that protect teenagers from statutory rape prosecution, and often from sex offender registration, when they have consensual sexual contact with a peer near their own age. Roughly 43 U.S. jurisdictions have some version of these protections. About 11 do not. The gap between a felony with lifetime registration and no criminal liability at all can come down to a single year of age difference or which side of a state line you were standing on.1U.S. Department of Justice. Conflicts Between State Marriage Age and Age-Based Sex Offense Laws
How the Age Math Works
The age of consent in the United States is either 16, 17, or 18 depending on the state, with 16 being the most common.2U.S. Department of Health and Human Services. Statutory Rape: A Guide to State Laws and Reporting Requirements Without an exemption, any sexual contact with someone below that threshold is a crime, full stop. A close-in-age exemption changes the analysis by looking at the age gap between the two people involved.
The permitted gap ranges from two to ten years depending on the jurisdiction. Four years is the most common threshold. A typical exemption works like this: if the older person is no more than four years older, and the younger person has reached a minimum age (often 13 or 14), the exemption applies. Federal sex offender registration law uses exactly this framework, excluding consensual conduct from its definition of “sex offense” when the younger person was at least 13 and the older person was not more than four years older.3Office of the Law Revision Counsel. 34 USC 20911 – Relevant Definitions
Two other numbers matter. Many states cap the older participant’s age, so once that person passes a certain birthday the defense disappears no matter what the actual gap is. Those caps usually fall between 19 and 21, though some sit as low as 16 or as high as 23. And most states set a floor for the younger person, commonly 13 or 14. Below that floor, even a one-year gap won’t trigger the exemption. The policy judgment behind the floor is that children below a certain age can’t meaningfully consent regardless of who the other person is.
Not Every State Has Them
This is the assumption that gets people in the most trouble: Romeo and Juliet laws do not exist everywhere. Around 11 jurisdictions have no close-in-age exception at all, though some of those impose lesser penalties when the participants are close in age.1U.S. Department of Justice. Conflicts Between State Marriage Age and Age-Based Sex Offense Laws In those states, a 17-year-old who has sex with a 15-year-old faces the same charge a 40-year-old would. The offense might drop to a misdemeanor because of the age gap, but the criminal record and possible registration still follow.
A few additional states only apply their exceptions in narrow situations, such as specific relationship categories. For typical teenage dating, those states offer little practical protection. Anyone assuming they’re covered without checking their own state’s code is taking a real risk.
Complete Defense, Affirmative Defense, or Charge Reduction
Not all close-in-age exemptions do the same work. How your state structures its exemption determines whether you avoid prosecution or just face a lighter charge.
- A complete defense eliminates criminal liability. If the age criteria are met and the conduct was consensual, no crime occurred. Prosecutors may decline to file charges once they confirm the ages.
- An affirmative defense means the conduct is still technically criminal, and the defendant raises the close-in-age facts at trial. The burden is on the defendant to prove them. An arrest, booking, and pretrial detention can still happen; the defense only helps once the case reaches court.
- A charge reduction doesn’t prevent a charge but lowers it, typically from a felony to a misdemeanor. That can cut potential jail time from years to months and often removes the registration requirement.
The practical difference is significant. Between a felony and a misdemeanor conviction sits everything from future employment to housing eligibility.
Sex Offender Registration and the Federal Exception
Avoiding registration is often the biggest benefit of a close-in-age exemption. Federal law under the Sex Offender Registration and Notification Act sets minimum registration periods of 15 years, 25 years, or life depending on the tier of offense.4Office of Justice Programs. The National Guidelines for Sex Offender Registration and Notification Registration brings residency restrictions, a bar on public housing, and employment obstacles that follow a person for decades.
SORNA itself carries a built-in Romeo and Juliet exception. Federal law excludes consensual conduct from the definition of “sex offense” when the younger person was at least 13 and the older person was not more than four years older.3Office of the Law Revision Counsel. 34 USC 20911 – Relevant Definitions So an 18-year-old and a 15-year-old in a consensual relationship fall outside SORNA’s federal reach.
SORNA also limits juvenile registration. A juvenile only has to register if they were at least 14 at the time of the offense and were adjudicated delinquent for a forcible sexual act.5Office of Justice Programs. Guide to SORNA Implementation in Indian Country Consensual peer activity without force falls outside that entirely.
One important boundary: SORNA is a federal floor, not a ceiling. States can require registration in cases that would fall inside the federal exception. Clearing the federal test doesn’t automatically clear the state one.
“I Thought They Were 18” Usually Isn’t a Defense
A widespread misconception is that believing the other person was of age offers legal cover. In most states, it doesn’t. Courts in roughly 30 or more states have ruled that mistake about the victim’s age is not a defense to statutory rape. In those jurisdictions the crime is strict liability: prosecutors only need to prove that sexual contact occurred and that the other person was underage. What the defendant believed, was told, or saw on an ID is legally irrelevant.
A 19-year-old who meets someone at a party, checks their ID, and sees an apparently valid license showing 18 can still be convicted if the person turns out to be 15 with a fake ID. A handful of states allow a reasonable-belief defense, and federal law explicitly permits one under 18 U.S.C. ยง 2243, where a defendant can prove by a preponderance of the evidence that they believed the other person was 16 or older.6Office of the Law Revision Counsel. 18 USC 2243 – Sexual Abuse of a Minor or Ward But treating that as the norm is a costly mistake.
When the Exemption Disappears
Even in states with generous protections, certain facts strip the exemption away entirely.
Force, Threats, or Coercion
Every close-in-age exemption requires that the activity was consensual. Physical force, threats, intimidation, or intoxication of the other person moves the case out of Romeo and Juliet territory and into standard sexual assault. The ages stop mattering.
Positions of Trust or Authority
A teacher, coach, counselor, or religious leader cannot claim a close-in-age defense even with only a two- or three-year age gap. The law treats those relationships as inherently unequal. Cases like these typically trigger enhanced penalties and mandatory registration. Some states define “position of authority” broadly enough to reach babysitters, employers, and foster parents.
Family Relationships
Incest statutes operate independently from age-of-consent laws. The relationship drives the charge, not the age gap, and close-in-age exceptions do not apply.
The Sexting Problem
Romeo and Juliet laws were written for physical contact. Most do not extend to explicit images. That creates a strange situation where two teenagers in a lawful sexual relationship under state law can be committing a federal felony by exchanging photos.
Federal child pornography law criminalizes the knowing production, transportation, receipt, distribution, or possession of any visual depiction involving a minor engaged in sexually explicit conduct.7Office of the Law Revision Counsel. 18 USC 2252 – Certain Activities Relating to Material Involving the Sexual Exploitation of Minors The statute has no safe harbor for minors who voluntarily create images of themselves. Its only affirmative defense covers someone who possessed fewer than three images and either destroyed them or reported them, which was designed for people who stumble across illegal material, not for teenagers with a boyfriend or girlfriend.
Roughly 27 states have passed some form of teen sexting law that reduces or redirects the penalties when minors share images with peers. These laws vary. Some make teen sexting a misdemeanor. Others divert cases to juvenile court or educational programs. Where no such law exists, prosecutors can charge minors under the same child pornography statutes used against adult predators, producing the paradox of a teenager labeled both perpetrator and victim of their own exploitation.
Consequences That Outlast the Case
Even when an exemption reduces a felony to a misdemeanor, a sex-related conviction can follow someone for a long time.
Federal regulations classify rape, sexual abuse, sexual assault, and other sex crimes as major misconduct offenses for military enlistment. Waivers are not authorized, and any conviction requiring sex offender registration permanently disqualifies an applicant.8eCFR. 32 CFR 66.7 – Enlistment Waivers The regulation does not carve out Romeo and Juliet situations.
Licensing boards for nursing, pharmacy, counseling, and education routinely ask about criminal history. Many have authority to deny, suspend, or revoke a license based on misdemeanor convictions involving moral turpitude, and a reduced sex offense charge can qualify. A conviction at 18 can block someone from a chosen profession at 25 without a single day of jail time.
Anyone required to register faces residency restrictions that vary by community. Federal law bars anyone on a state sex offender registry from public housing. Beyond those legal limits, a sex-related entry on a background check creates barriers to employment and housing that persist long after any sentence ends.
Same-Sex Couples
Historically, some close-in-age exemptions were written in gendered language that only covered opposite-sex couples. Constitutional developments have invalidated many of those distinctions, but the statutory text has not been updated in every state. Where the words still reference conduct between a male and female, there is at least a theoretical risk that a court could read the statute narrowly. Unequal application would face serious constitutional challenges if litigated, but equal protection under these laws is not guaranteed everywhere on the face of the code.
If you’re trying to figure out whether these protections apply to a specific situation, the answer lives in your state’s statute, not in general summaries. The ages, the gap, the state, and the facts around consent all move the outcome. Talk to a criminal defense attorney in your jurisdiction before assuming the law is on your side.
