Get Help With the Following Ontario, CA, Sex Crime Charges
Rape and Sexual Assault
Rape is arguably the most serious sex crime charge you can face in Ontario, CA. A conviction can send you to prison for years, and permanently put you on the sex offender registry. Rape is one form of sexual assault. Sexual assault is not defined on its own in California law, but instead is a term used to describe a category of violent offenses of a sexual nature.
Spousal rape under former PC § 262 was repealed in 2021. As of January 1, 2026, SB 258 also removed the remaining spouse-capacity carve-out in PC § 261. Rape inside a marriage is charged like rape between any other two people.
Child Sex Crimes
Child sex crimes are some of the most harshly viewed accusations in Ontario, CA, making it essential to work with an experienced sex crimes lawyer to fight them. Even in cases where there wasn't a physical, sexual act involving a child, you can face charges for enticing a minor for lewd purposes.
Statutory Rape
Unlawful sexual intercourse with a minor is a misdemeanor or a wobbler depending on ages. Important 2026 change: for offenses on or after January 1, 2026, SB 680 added certain PC § 261.5(c) and (d) convictions to PC § 290. Those cases can require Tier 1 (10-year) registration, unless the defendant was not more than 10 years older than the minor and that is the only registerable conviction. Courts can still order registration under PC § 290.006. Offenses before January 1, 2026 are not brought onto the registry by SB 680. This should be analyzed before any plea.
Internet and Digital Sex Crimes
Online and digital sex crimes can be particularly complicated in California. For example, sexting with a minor is illegal, even if the supposed minor turned out to be an adult who was pretending. This is because the relevant statute (PC § 288.2) applies if the alleged offender believed they were talking to a minor, even if that wasn't true. Sexting can also overlap with stalking charges.
Deepfake Sexual Content
Deepfake sexual content can lead to serious criminal charges. California law has made it illegal to share photorealistic, intimate images of an identifiable person, even if they are artificial or AI-generated. A first conviction is a misdemeanor with a maximum penalty of six months in jail and a $1,000 fine, while repeat convictions can be punished with up to one year in jail and a $2,000 fine.
Prostitution
Prostitution has a long history in the United States, but is currently illegal in California. The state defines prostitution as exchanging a sexual act for something of value, which is often (but not always) money. The same law covers both acting as a prostitute and soliciting a prostitute, and the penalties include up to six months in jail and/or a $1,000 fine. Additionally, sentence enhancements can add mandatory minimums of jail time and/or the suspension of your driver's license.
Related Charges
In Ontario, CA, we also defend indecent exposure (PC § 314), lewd conduct in public (PC § 647(a)), failure to register (PC § 290.018), human trafficking (PC § 236.1), incest (PC § 285), aggravated sexual assault of a child (PC § 269), and assault with intent to commit a sex offense (PC § 220).

Ontario, CA, Sex Crimes Lawyer Guidance at Every Stage of Your Case
Pre-filing and investigation. Your defense doesn't begin when charges are filed — you should call a sex crimes lawyer in Ontario, CA, if you even think you are under investigation. We can help you set up your future case for a positive outcome, or avoid court entirely.
Discovery and forensics. We obtain police reports, body-cam footage, SART/rape-kit notes, pretext-call recordings, phones, cloud accounts, and expert review of DNA, toxicology, and digital media. Many cases turn on delayed disclosure, inconsistent statements, suggestive interviewing of children, or missing intent.
Motions. Suppression. The right motions can set your case up for success. In addition to motions we commonly file (like suppression and dismissal), in sex crime cases we often file a motion to suppress identification. Unfortunately, misidentification can occur more often than it should in criminal cases, and sex crimes are no exception.
Negotiation. The registration tier often matters more than a few months of custody. Reducing a Tier 3 offense to a non-registerable or Tier 1/2 charge can be the entire case.
Trial and sentencing. Not every plea deal offered is acceptable. If we can't find an option that works for you, we're prepared to fight in court for your freedom. Even if the outcome at trial isn't what you were hoping for, we'll advocate for lenient sentencing.

California's Three-Tier Sex Offender Registry System
California uses a three-tier system (SB 384, in effect since 2021):
- Tier 1 — generally 10 years (5 years in some juvenile cases). Examples: many misdemeanor sexual battery and indecent exposure convictions; some PC § 261.5 convictions for offenses on or after January 1, 2026, under SB 680.
- Tier 2 — generally 20 years. Examples: many serious/violent registerable felonies that are not automatic lifetime.
- Tier 3 — lifetime for the most serious offenses (e.g., sex trafficking of a child, sodomy by force, forcible rape) and certain repeat or high-risk designations.
On top of the lengthy time periods of registration, failure to register is an offense in and of itself. While on the registry, you can be facing challenges finding a house or job, restrictions on where you are able to travel, and a devastating social stigma. Your sex crimes lawyer can help you petition for removal once you're eligible for relief.

- Technical issues with the way the case was filed
