Unlawful Intercourse With a Minor in California — What the Charge Means and How It's Defended

Penal Code § 261.5 — commonly called statutory rape — is unique among California sex offenses in one important respect: consent is not a defense. A minor under 18 cannot legally consent to sexual intercourse under California law, regardless of their expressed willingness. The charge is based entirely on age, and a defendant's belief that the minor was older — even a reasonable, good-faith belief — is not a complete defense under California's current framework. At the Law Office of Nic Cocis, we defend § 261.5 charges in Murrieta and Southwest Riverside County with a clear-eyed analysis of what the statute requires and where the defense actually lives.

How California Charges Unlawful Intercourse With a Minor

The Age Gap Determines the Charge Level

Section 261.5 makes it unlawful for any person to engage in sexual intercourse with a person under 18 who is not the spouse of the defendant. Unlike most California sex offenses, § 261.5 is not a registration offense — a conviction does not automatically trigger sex offender registration under § 290. That distinction matters significantly in evaluating the consequences of a charge.

The specific charge and penalty depend on the age difference between the parties:

Both parties are minors, or the age difference is less than three years: § 261.5(b) — misdemeanor only. This is the provision that applies when a 17-year-old and a 15-year-old are involved, for example. No felony exposure.

The defendant is 21 or older and the minor is under 16: § 261.5(d) — straight felony. Two, three, or four years in state prison. This is the most serious state-only configuration under the statute.

The age difference is more than three years (and neither party is under 16): § 261.5(c) — wobbler. Chargeable as a misdemeanor or a felony. Up to one year in county jail as a misdemeanor; 16 months, two, or three years in state prison as a felony.

Civil penalties also apply under § 261.5(e): up to $2,000 if the minor is under 16 and the adult is 21 or older; up to $25,000 if the minor is under 16 and the defendant is 21 or older and the relationship is more than three years. These are civil assessments, not criminal fines, but they’re part of the overall consequence picture.

The Age Mistake Question

California courts have held that a reasonable, good-faith mistake about the minor's age is not a complete defense to § 261.5 in most circumstances — a position that differs from some other states. The California Supreme Court's analysis in People v. Hernandez (1964) allowed the mistake-of-age defense in some circumstances, but subsequent case law has narrowed it. Whether mistake of age remains viable depends on the specific facts, the age gap, and the circumstances of the parties' meeting and communication. We assess the mistake-of-age argument in every case where the facts potentially support it.

How We Can Help

The defense in a § 261.5 case focuses on the age gap determination, the specific charge level, the evidence of the sexual act, and — where relevant — the circumstances surrounding the parties' relationship.

What to Expect When You Work with Us

01

Age and Evidence Analysis

We examine the evidence establishing the ages of both parties and the evidence of the sexual act itself. In cases where the minor's age was misrepresented or where the evidence of the act is limited, the prosecution's case may be weaker than it appears.

02

Wobbler Treatment

For § 261.5(c) charges — the three-year-plus age gap wobbler — we pursue misdemeanor treatment where the circumstances support it. The difference between a felony and a misdemeanor conviction has substantial long-term consequences for employment and licensing.

03

No-Registration Advantage

Unlike most sex offense convictions, a § 261.5 conviction typically does not trigger § 290 sex offender registration. This is a meaningful distinction we use in evaluating plea options — a § 261.5 plea may be significantly preferable to a plea to a different charge that does trigger registration.

Immigration Assessment

For non-citizen defendants, a § 261.5 conviction may constitute a crime involving moral turpitude with immigration consequences. We evaluate this issue before any plea recommendation.

Frequently Asked Questions

It may be, depending on the circumstances. California has recognized a mistake-of-age defense in cases where the defendant had a good-faith, reasonable belief that the person was of legal age, and that belief was based on something more than the minor's unverified claim. A fake ID, independent representations by the minor, and circumstances under which no reasonable person would have suspected the person was a minor are all relevant. The strength of this defense depends on the specific facts and the defendant's actual conduct — and it's not available in all § 261.5 circumstances. We assess it honestly.

Generally no. Section 261.5 is not listed as a mandatory registration offense under Penal Code § 290 in most circumstances. This is a significant distinction from many other sex offense charges and an important factor in plea evaluation. There are circumstances in which registration could be imposed — if the conduct also supports a separate registration-required charge, or if the case is resolved to a different offense — but a standard § 261.5 conviction typically does not carry registration. We confirm the registration status of every possible outcome before any plea is entered.

Yes, in most cases. A § 261.5 conviction is eligible for expungement under Penal Code § 1203.4 after successful completion of probation, subject to the general expungement requirements. Expungement dismisses the conviction for most employment purposes but does not affect immigration consequences or any civil penalty assessment. We advise on expungement eligibility at the conclusion of every case.
