Overview

Louisiana sets its age of consent at 17. La. R.S. 14:80 makes it felony carnal knowledge of a juvenile for someone 17 or older to have sexual intercourse with someone 13 through 16, but only where the age gap is four years or greater. Below that gap, this specific felony provision does not apply.

A related, less serious offense, misdemeanor carnal knowledge of a juvenile under La. R.S. 14:80.1, is referenced in the felony statute as applying to repeat offenders. This guide could not confirm the full independent criteria of that misdemeanor statute from the sources it reviewed.

Close-in-age rules in Louisiana

Section 14:80(A)(1) requires the age gap to be four years or greater. If the offender is less than four years older than a victim 13 through 16, this specific felony provision does not reach the conduct.

A related misdemeanor statute exists but is not fully detailed here. Section 14:80(A)(2) references misdemeanor carnal knowledge of a juvenile as applying to repeat offenders or those already required to register as sex offenders. This guide could not independently confirm the complete standalone criteria of that misdemeanor statute, La. R.S. 14:80.1, and does not assume it mirrors the felony statute’s four-year threshold.

Exceptions and defenses

The statute explicitly states that lack of knowledge of the juvenile’s age is not a defense. Marriage between the two people is a stated exclusion from Section 14:80. For a victim under 13, more serious offenses apply, including aggravated rape-related statutes carrying penalties up to 20 years, with no close-in-age allowance described in the sources this guide reviewed.

Practical examples

These are simplified, hypothetical illustrations only, not legal advice, and not a prediction of any real case’s outcome.

Example 1. A 16-year-old and an 18-year-old, a two-year gap. Because the gap is under four years, felony carnal knowledge under Section 14:80 does not reach this conduct.

Example 2. A 15-year-old and a 20-year-old, a five-year gap. This meets the four-year threshold, so felony carnal knowledge of a juvenile applies.

Example 3. A 12-year-old and a 16-year-old, a four-year gap. Because the victim is under 13, Section 14:80 does not apply at all; a more serious offense applies instead.

Frequently asked questions about Louisiana

What is the age of consent in Louisiana?

17. La. R.S. 14:80 makes it felony carnal knowledge of a juvenile for someone 17 or older to have sexual intercourse with a 13–16 year old, but only where the gap is four years or greater.

Does Louisiana have a Romeo and Juliet law?

Yes, a genuine one. The felony statute does not reach the conduct at all where the gap is under four years, functioning as a real exemption rather than a defense raised in court.

Is there a lesser charge for a smaller gap?

A misdemeanor version of the statute exists and is referenced for repeat offenders, but this guide could not independently confirm its complete standalone criteria.

Does a mistaken belief about age count as a defense?

No. The statute explicitly states that lack of knowledge of the juvenile’s age is not a defense.

Are married couples treated differently?

Yes. Marriage between the two people is a stated exclusion from Section 14:80.
