Unlawful Sexual Conduct With a Minor: Penalties and SORNA Registration

Unlawful sexual conduct with a minor is any sexual act or sexual contact involving a person under the age of consent, and a conviction brings some of the heaviest penalties in American criminal law: federal mandatory minimums reaching 30 years to life, mandatory sex offender registration that can last a lifetime, and restrictions on travel, employment, housing, and parental rights that continue long after prison ends.

What the Law Actually Covers

Federal law separates two kinds of conduct, and the line between them drives which statute applies. A sexual act means penetration of a genital or anal opening by a body part or object (no matter how slight), oral contact with sex organs, or intentional touching of the genitalia of anyone under 16 done to gratify sexual desire. Sexual contact is broader: any intentional touching of intimate areas, directly or through clothing, done with sexual or abusive intent.¹

The most serious federal charge is aggravated sexual abuse of a child under 12. Under 18 U.S.C. § 2241(c), anyone who crosses a state line intending to commit a sexual act with a child under 12, or commits one within federal jurisdiction, faces a mandatory minimum of 30 years and a maximum of life. The same statute covers sexual acts committed through force or threats against a victim between 12 and 16 who is at least four years younger than the offender.²

Where no force is involved but the victim is between 12 and 15 and at least four years younger than the offender, the charge falls under 18 U.S.C. § 2243, with up to 15 years in prison.³ When the conduct is sexual contact rather than a sexual act, 18 U.S.C. § 2244 carries up to 10 years if the contact would have been aggravated sexual abuse had it gone further, or up to two years for contact with a minor under the age-gap provisions. All of these penalties double when the victim is under 12.⁴

Producing, distributing, or possessing sexually explicit material involving minors is a separate category. Under 18 U.S.C. § 2251, producing such material carries a mandatory minimum of 15 years and a maximum of 30 for a first offense, 25 to 50 years for a second, and 35 to life for a third. If the conduct causes a child’s death, the penalty is death or a minimum of 30 years.⁵

Age of Consent and Close-in-Age Rules

Every state sets an age of consent, and across the 50 states that threshold falls between 16 and 18, with most states setting it at 16. Anyone who engages in sexual conduct with someone below that threshold can face charges regardless of whether the minor appeared willing or initiated the encounter. The minor’s apparent maturity or verbal agreement is legally meaningless, because the law treats consent from a minor as invalid by definition.

Federal law uses its own framework. Under § 2243, the federal age cutoff is 16, and the statute requires at least a four-year age gap between offender and minor before criminal liability attaches.³ That four-year gap functions as a built-in close-in-age provision, keeping two teenagers close in age out of the same category as an adult targeting a child.

Many states have enacted their own close-in-age exemptions, sometimes called “Romeo and Juliet” laws, which reduce or eliminate penalties when both parties are teenagers or when the age difference falls within a narrow window — typically two to four years. Specifics vary widely. Some states make the conduct legal, others reduce it from a felony to a misdemeanor, and some simply shield the older party from sex offender registration.

Can You Defend by Saying You Thought the Minor Was Older

Almost never. The overwhelming majority of states treat sexual conduct with a minor as a strict liability offense: the prosecution does not have to prove the defendant knew the victim’s age. Being misled by appearance, a fake ID, or an explicit statement about age does not defeat the charge in most jurisdictions.

Federal law is slightly more forgiving in one narrow slice. Under 18 U.S.C. § 2243(d), a defendant charged with sexual abuse of a minor between 12 and 15 may raise a defense that they reasonably believed the other person was at least 16. The defendant bears the burden of proving this by a preponderance of the evidence. The government is not required to prove the defendant actually knew the victim’s age or that the age gap existed.³ The defense is narrow and difficult to win. It does not apply at all to offenses involving children under 12, where liability is absolute.

Prison Penalties and Mandatory Minimums

Federal sentencing is built so the most serious conduct triggers the longest mandatory terms. Penalties escalate with the victim’s age, the type of conduct, whether force was used, and whether the defendant has prior convictions.

Aggravated sexual abuse of a child under 12 (§ 2241(c)): mandatory minimum of 30 years, maximum of life.²
Aggravated sexual abuse by force or threats (§ 2241(a)-(b)): any term of years up to life.²
Sexual abuse of a minor aged 12 to 15 without force (§ 2243(a)): up to 15 years.³
Abusive sexual contact (§ 2244(a)(1)): up to 10 years; penalties double if the victim is under 12.⁴
Producing child sexual abuse material (§ 2251): 15 to 30 years for a first offense; 25 to 50 for a second; 35 to life for a third.⁵

Mandatory minimums drive outcomes. United States Sentencing Commission data shows that offenders sentenced under mandatory minimum provisions receive prison terms roughly three times longer than those convicted of similar offenses without a mandatory floor.⁶ Judges cannot impose a lighter sentence based on cooperation, remorse, or personal circumstances once a minimum applies. State penalties vary but frequently mirror this structure, with felony classifications carrying five to fifteen years for initial offenses and indeterminate life sentences for the most serious acts or repeat offenders.

On top of prison time, every conviction under the federal sexual abuse and exploitation statutes triggers mandatory restitution. Courts cannot waive it. Restitution covers the victim’s full losses — medical treatment, therapy, lost income, and other costs caused by the offense — with a $3,000 floor per defendant for offenses involving child sexual abuse material.⁷

Sex Offender Registration Under SORNA

The Sex Offender Registration and Notification Act (SORNA) requires convicted sex offenders to register in every jurisdiction where they live, work, or attend school. Registration must happen before the offender finishes a prison sentence, or within three business days of sentencing if no prison term is imposed. Any change of name, address, job, or school enrollment requires an in-person update within three business days.⁸ Required information includes every residential address, employer name and address, school enrollment, vehicle plates and descriptions, Social Security number, and detailed international travel plans.⁹

How Long Registration Lasts

SORNA sorts offenders into three tiers based on the severity of the underlying offense:

Tier I is a catch-all for sex offenses not severe enough to qualify as Tier II or III. Registration lasts 15 years.¹⁰
Tier II covers offenses punishable by more than one year that involve sex trafficking of a minor, enticement or transportation of a minor for sexual activity, abusive sexual contact with a minor, use of a minor in a sexual performance, or production and distribution of child sexual abuse material. It also captures anyone who commits a new offense after qualifying as Tier I. Registration lasts 25 years.¹⁰
Tier III covers offenses comparable to aggravated sexual abuse or sexual abuse under §§ 2241–2242, abusive sexual contact with a child under 13, kidnapping of a minor by someone other than a parent, or any offense committed after qualifying as a Tier II offender. Registration lasts for life.¹⁰

Registry information is made available through searchable public databases for the full duration of the registration period. Failing to register or update registration information is a separate federal felony under 18 U.S.C. § 2250, punishable by up to 10 years. If the offender commits a violent crime while unregistered, the penalty jumps to a mandatory minimum of five years and a maximum of 30, imposed on top of whatever sentence the new crime carries. Failing to report international travel plans before leaving the country is separately punishable by up to 10 years.¹¹

Life After Prison

The formal sentence is only the start. A conviction for a sex offense involving a minor sets off a cascade of restrictions that reach into nearly every part of daily life, and many of them have no end date.

Supervised Release and Polygraphs

Federal sex offenders do not simply walk free when their prison term ends. Under 18 U.S.C. § 3583(k), the court must impose a term of supervised release of at least five years after imprisonment and can impose lifetime supervision. This applies to all federal sexual abuse offenses, sexual exploitation under § 2251, and failure to register under § 2250. If a person on supervised release commits another qualifying sex offense, the court must revoke supervision and impose at least five more years of imprisonment.¹²

Conditions during supervised release are invasive by design. Courts routinely require periodic polygraph examinations, typically every six months, covering sexual behaviors, victim-related contact, and high-risk activities. A polygraph result alone cannot be the sole basis to revoke supervision, but it can lead to increased monitoring, modified treatment plans, or a separate investigation.¹³ Computer monitoring, curfews, restrictions on internet access, and prohibitions on contact with minors are also standard.

Passport Marking and International Travel

Under 22 U.S.C. § 212b, the State Department must place a unique visual identifier on the passport of any registered sex offender, and can revoke a previously issued passport that lacks the marking. The identifier sits in a conspicuous location, signaling the holder’s status to border officials in any country.¹⁴ Separately, the Angel Watch Center and the U.S. Marshals Service are authorized to notify destination countries when a registered offender is traveling internationally.¹⁵ Many countries deny entry outright to anyone flagged through this system.

Employment and Housing

Sex offense convictions create near-permanent barriers to employment in many fields. A significant number of states have enacted licensing reforms allowing people with criminal records to obtain professional licenses, but most of those reforms explicitly carve out sexual offenses. Licensing boards retain broad discretion to deny applicants with sex offense convictions regardless of rehabilitation, the passage of time, or whether the conviction relates to the profession. Fields involving contact with children, vulnerable populations, or health care are effectively closed off permanently in many jurisdictions.

Residency restrictions add another layer. Many local and state laws prohibit registered sex offenders from living within a set distance of schools, daycare centers, parks, and playgrounds. The restricted zone is commonly 1,000 feet, though some jurisdictions draw it wider. In urban areas where schools and parks are densely distributed, finding legal housing becomes extremely difficult.

Parental Rights and Custody

A conviction can directly threaten parental rights. Many states authorize courts to terminate the parent-child relationship when the parent has been convicted of a sexual offense against a child, including cases where the child was conceived through the assault. Courts are not required to make any effort to reunify the family before terminating rights in these cases. Even outside termination proceedings, a sex offense conviction heavily influences custody decisions, often resulting in supervised visitation or complete denial of contact with the offender’s own children.

Factors That Push Penalties Higher

Certain circumstances push charges into higher penalty tiers, and prosecutors look for them when building a case.

A position of trust or authority over the victim is one of the most significant aggravators. Under the federal sentencing guidelines, abusing a position of public or private trust to facilitate a sex offense increases the offense level by two points, which translates into meaningfully longer prison time.¹⁶ Teachers, coaches, clergy, foster parents, and relatives who exploit their access to a child face this enhancement.

The victim’s age is the other major driver. Offenses against children under 12 trigger the harshest penalties across the board: a 30-year mandatory minimum under § 2241(c) for sexual acts and doubled maximum sentences for sexual contact under § 2244(c).²⁴ Use of force, threats of violence, or kidnapping also triggers the highest classifications. And prior convictions create a ratchet effect: each subsequent offense raises both the mandatory minimum and the maximum, with third offenses for sexual exploitation carrying a floor of 35 years.⁵

How Long Prosecutors Have to File Charges

Federal law effectively eliminates the statute of limitations for sexual offenses against children. Under 18 U.S.C. § 3283, prosecution for any offense involving the sexual abuse of a child under 18 can be brought at any time during the life of the child, or within 10 years after the offense, whichever is longer.¹⁷ In practice, that means a person who sexually abused a child can be prosecuted decades later.

State statutes of limitations vary but have been moving in the same direction. Many states have eliminated time limits entirely for the most serious sexual offenses against children. Others have extended their windows to 20 or 30 years after the victim turns 18, and some toll the limitations period while the victim is still a minor, so the clock does not start running until the victim reaches adulthood.
