Connecticut Age of Consent: Laws, Exceptions, and Charges

The Connecticut age of consent is 16. Once a person turns 16, state law no longer treats age alone as a bar to consensual sexual activity. Two important qualifications sit on top of that rule: the threshold rises to 18 when the older person holds authority over the younger one, and a close-in-age exception shields some teenagers from prosecution for relationships with peers.

The Baseline: 16

Below 16, Connecticut considers a person legally incapable of consenting, no matter what they say or do at the time.¹ The state’s sexual assault statutes, from first through fourth degree, all draw their age-based lines from that baseline. The core definitions — sexual intercourse, sexual contact, and the conditions that negate consent — appear in § 53a-65 of the General Statutes and apply across every sexual offense in the code.

The Close-in-Age Exception

Connecticut carves out a narrow gap for teenagers close in age. Sexual intercourse with someone who is 13, 14, or 15 is not second-degree sexual assault if the older person is no more than three years older.² A 17-year-old and a 14-year-old fit inside the exception. An 18-year-old and a 14-year-old do not.

A parallel rule governs sexual contact rather than intercourse. Fourth-degree sexual assault requires the older person to be more than three years older when the younger person is 13 or 14, or more than two years older when the younger person is under 13.³ Nothing in the exception applies to a child under 13 in a first-degree case where the older person is more than two years older; that is a Class A felony regardless of the specific age gap.

When the Threshold Rises to 18

Age 16 is not the answer if the older person occupies a position of power or trust over the younger one. In those relationships, Connecticut treats the effective age of consent as 18.

The fourth-degree statute covers sexual contact between anyone under 18 and their guardian or a person “otherwise responsible for the general supervision” of that minor’s welfare, along with anyone holding supervisory or disciplinary authority over a person in legal custody or detained in a hospital or institution.³ The second-degree statute mirrors these provisions for sexual intercourse in the same authority relationships.²

In practice these provisions reach teachers, coaches, school employees, psychotherapists, probation officers, and similar figures. The “general supervision of welfare” language is deliberately broad, and the roles listed in the statute are not an exhaustive set.

When Consent Doesn’t Count Above 16

Even someone 16 or older cannot consent under Connecticut law in three specific conditions. The definitions are narrower than most people assume.

Mentally incapacitated. This applies only when another person administered drugs or intoxicants without consent, or committed some other act on the person without consent, leaving them temporarily unable to understand or control their conduct. Voluntary intoxication alone does not meet the statutory definition.⁴

Mentally defective. This covers a person whose mental disease or defect makes them permanently incapable of understanding the nature of sexual conduct. It is an ongoing condition, not a temporary state.

Physically helpless. A person who is unconscious or otherwise unable to communicate unwillingness to an act. Courts have said that physical incapacity by itself does not automatically make someone physically helpless; what matters is whether the person could communicate a lack of consent at the time.⁵

Charges When the Line Is Crossed

Connecticut’s charging structure is graduated. The gap between the lowest and highest charges is the difference between a misdemeanor and a life-changing prison sentence.

First-Degree Sexual Assault

Under § 53a-70, sexual intercourse involving force or threat of force, or with a victim under 13 when the offender is more than two years older, is first-degree sexual assault. It is a Class B felony by default and a Class A felony when both force and a victim under 16 are involved, or when the victim is under 13.⁶

Second-Degree Sexual Assault

This is the charge most directly tied to age-of-consent violations. Under § 53a-71, intercourse with someone 13 to 15 is second-degree sexual assault when the older person is more than three years older. The default is a Class C felony, punishable by 1 to 10 years and a fine up to $10,000. When the victim is under 16, the offense is elevated to a Class B felony, carrying 1 to 20 years and a fine up to $15,000.²⁷ Any conviction under this section carries a mandatory nine-month minimum that the court cannot suspend or reduce. The same statute covers intercourse in the authority-figure situations described above.

Fourth-Degree Sexual Assault

Fourth-degree charges under § 53a-73a cover sexual contact rather than intercourse. The offense is a Class A misdemeanor or a Class D felony depending on the circumstances.³ The misdemeanor version carries up to one year in jail; the felony version, up to five years.

Risk of Injury to a Minor

Prosecutors often stack a charge under § 53-21 alongside sexual assault charges. The statute makes it a Class C felony to put a child under 16 in a situation likely to impair their health or morals. Its sexual-contact subsection carries up to 10 years and a $10,000 fine, and it registers on the criminal record as its own conviction.

Sexting: A Trap the Consent Rule Doesn’t Cover

Being at or above the age of consent does not authorize minors to share sexually explicit images of themselves or peers. Under § 53a-196h, it is a Class A misdemeanor for anyone under 16 to transmit a sexually explicit image of themselves to another person under 18, and a Class A misdemeanor for anyone under 18 to possess such an image where the person depicted is under 16 and transmitted it voluntarily.⁸

Federal law adds a harsher layer. Under 18 U.S.C. § 2256, any sexually explicit image of a person under 18 is child pornography regardless of state consent ages, and federal distribution charges carry a five-year mandatory minimum for a first offense.⁹ Federal prosecutors rarely target typical teenage sexting, but the exposure exists, especially once an image spreads beyond its original recipient.

How Long the Exposure Lasts

Connecticut has essentially eliminated the statute of limitations for sexual offenses against minors. Under Public Act 19-16 there is no time limit for prosecuting any offense involving sexual abuse, sexual exploitation, or sexual assault of a minor, including risk-of-injury charges involving sexual contact with a victim under 16. First-degree sexual assault involving a victim under 16, or a victim under 13 where the offender is more than two years older, is a Class A felony and also has no time limit. The same is true for aggravated sexual assault of a minor and commercial sexual abuse of a minor under 15.⁶ Someone who commits a sexual offense against a minor in Connecticut can be charged decades later.

Sex Offender Registration

Conviction for any of the offenses above triggers Connecticut’s registration requirement. A first conviction for a criminal offense against a minor victim or a nonviolent sexual offense requires ten years of registration after release into the community. A second or later conviction in those categories, or any conviction for a sexually violent offense, requires lifetime registration. Conviction under § 53a-70(a)(2) — sexual assault of a child under 13 by an offender more than two years older — carries lifetime registration on a first offense.¹⁰

Registration means providing a name, address, photograph, employer information, and electronic communication identifiers to the Department of Emergency Services and Public Protection. The registry is public, and the obligation follows a person wherever they move.
