In California, the legal term “oral copulation” refers specifically to any act involving contact between one person’s mouth and another person’s sexual organs or anus.

Under state law, oral copulation becomes a criminal offense when it occurs without clear consent, involves coercion or force, or involves a minor or someone incapable of giving consent. Understanding this clearly is critical, especially if you’re facing accusations or charges related to these offenses.

Offenses involving oral copulation carry harsh consequences in California, from serious felony convictions to mandatory registration as a sex offender. Because the penalties are so severe, if you or someone you know has been accused of an offense involving oral copulation, it’s important to speak with a skilled Los Angeles sex crimes lawyer.

Common charges involving oral copulation in California

Two frequent types of criminal charges involving oral copulation in California are oral copulation by force or fear and oral copulation with a minor. Each carries serious penalties and distinct legal elements prosecutors must prove.

Oral copulation by force or fear

Oral copulation by force or fear occurs when someone uses force, violence, threats, coercion, or fear to make another person participate in oral copulation. Under California Penal Code § 287(c), prosecutors must prove that the accused:

  • Engaged in oral copulation with another person, and
  • Did so by means of force, violence, duress, menace, or threats of harm to the victim or someone else.

Examples include situations where an individual is threatened with physical harm if they do not comply or when physical force or violence is used to compel compliance. Importantly, the level of force doesn’t have to cause significant injury—it only needs to be sufficient to overcome the victim’s will or consent.

Penalties for oral copulation by force or fear can include severe felony charges, significant state prison sentences (often ranging from three to eight years or more), fines, restitution to the victim, and mandatory registration as a sex offender for life under California Penal Code Section 290.

Oral copulation with a minor

Oral copulation involving a minor refers specifically to sexual contact where one participant is under the age of 18. Unlike cases involving force, these charges often apply even if the minor willingly participates or consents, as California law states clearly that minors cannot legally consent to such acts.

The exact penalties depend largely on the age of the minor and the age difference between the parties involved. Situations involving minors aged 16 or 17 and defendants who are close in age (within a few years) might result in misdemeanor charges. However, substantial age differences typically result in felony charges with severe penalties, including lengthy imprisonment and mandatory lifetime registration as a sex offender.

In addition, when the minor is under 14, the charges are particularly severe, and defendants face significant state prison time, lifetime sex offender registration, and additional restrictions even after release.

Defenses against charges involving oral copulation

Oral copulation is legal, of course, if it takes place between consenting adults. This means that defending against oral copulation charges requires careful analysis of the specific allegations and circumstances. Common defenses include:

  • Consent – In cases involving adults, establishing clear and voluntary consent is crucial. If the defendant reasonably believed there was consent and no coercion or threats were used, this can form the basis of a strong defense.
  • Lack of force or coercion – If force or fear is alleged, your attorney might present evidence that no coercion occurred and the interaction was consensual.
  • False allegations or mistaken identity – Defendants sometimes face false accusations motivated by anger, jealousy, or misunderstandings. Demonstrating inconsistencies in the alleged victim’s statements or timeline can strengthen a defense.
  • Age-related defenses – In certain cases involving minors, a defense may involve showing reasonable belief the minor was of legal age. While challenging, this defense can sometimes be valid, particularly in cases where age was misrepresented or unclear.

Beyond the immediate legal penalties, a conviction for oral copulation offenses carries lasting consequences, including mandatory sex offender registration, limitations on where you can live or work, and serious damage to your personal and professional reputation. Early intervention by an experienced criminal defense lawyer can significantly impact your chances of avoiding or reducing these severe outcomes.
