California has the most extensive set of deepfake laws of any US state. The framework spans criminal liability for non-consensual intimate deepfakes, civil remedies for victims, election deepfake rules, AI content transparency requirements, and protections for performers and the deceased. This guide covers every California deepfake statute that lawyers and compliance teams need to know in 2026, with effective dates, penalties, and enforcement authorities.
If you operate an AI platform, social media service, content creation tool, political campaign, film studio, or any business that creates or distributes synthetic media in California, you are likely subject to one or more of these statutes.
The California deepfake statutes at a glance
California's deepfake framework grew out of three policy waves:
- 2019–2024: Criminal and civil liability for sexual deepfakes — AB 602 (civil cause of action), AB 730 (election deepfakes), and Penal Code § 647(j)(4) (criminal NCII).
- 2024 wave: 18 AI bills signed by Governor Newsom — including SB 926 (criminal NCII deepfakes), SB 981 (platform reporting), AB 1831 (AI-generated CSAM), AB 2655 (election platform duties), AB 1836 (digital replicas of the deceased), and SB 942 (the AI Transparency Act).
- 2025–2026 strengthening: AB 621 raised civil penalties for non-consensual deepfake pornography to $50,000 (up from $30,000) and $250,000 with malice (up from $150,000), and expanded the definition to include any image “created or substantially altered through digitization.”
Sexual deepfakes: criminal liability
Penal Code § 647(j)(4) — Non-consensual deepfake intimate imagery
It is a crime to distribute, without consent, realistic intimate images of an identifiable person that were “created or altered digitally or by computer or AI to appear authentic to a reasonable person,” if the defendant knew or should have known the distribution would cause serious emotional distress. First-time misdemeanor: up to 6 months in county jail and a $1,000 fine. If the depicted person was a minor, penalties rise to up to 364 days in jail and a $2,000 fine; repeat offenses involving minors can be charged as a felony.
SB 926 — Criminal deepfake pornography
Criminalizes creating and distributing non-consensual deepfake intimate imagery with intent to cause serious emotional distress. Provides a private right of action for victims to sue for damages. Enforced by the California Attorney General; violations may result in civil penalties, fines, or criminal charges depending on severity.
AB 1831 — AI-generated child sexual abuse material
Expands existing child pornography laws to include content that is digitally altered or generated by AI. Closes the “no real child was harmed” defense for AI-generated CSAM.
Sexual deepfakes: civil remedies
AB 621 — Expanded civil liability for digitized sexually explicit material (2026 update)
Recasts and extends Civil Code § 1708.8. Maximum civil penalty for a depicted individual rises from $30,000 to $50,000, and from $150,000 to $250,000 for violations committed with malice. Crucially, “digitized sexually explicit material” now includes any image or audiovisual work “created or substantially altered through digitization,” bringing AI-generated deepfakes squarely within the scope of California’s privacy torts.
SB 981 — Platform reporting and removal
Requires social media platforms operating in California to provide a reporting mechanism for sexually explicit digital identity theft (including deepfakes). Platforms must temporarily block reported content during investigation and permanently remove it if confirmed.
Election deepfakes
AB 2655 — Defending Democracy from Deepfake Deception Act
Requires large online platforms (1M+ California users) to block or label “materially deceptive” election content during the 120 days before an election and on election day. Requires reporting procedures and removal of flagged content. Applies to both political ads and organic content.
AB 2355 — Disclosure for AI-altered political ads
Requires “qualified political advertisements” that contain AI-generated or substantially altered images, audio, or video to include clear disclosures stating that the ad was generated or altered using AI.
AB 2839 — Prohibition on materially deceptive election content
Prohibits knowingly distributing, with malice, election advertisements containing “materially deceptive content” within 120 days of an election (and 60 days after, in some cases). A federal district court preliminarily enjoined this law on First Amendment grounds; campaigns and platforms should consult counsel before relying on its enforceability.
Performer and likeness rights
AB 2602 — Digital replicas in entertainment contracts
Heightens consent requirements for the use of an actor’s “digital replica.” Contracts must include a reasonably specific description of the proposed use, and the actor must be represented by legal counsel or by a labor union, or the contract is unenforceable.
AB 1836 — Digital replicas of the deceased
Prohibits unauthorized commercial use of a deceased person’s digital replica without consent from their estate. Damages are $10,000 or actual damages, whichever is greater. Protections apply for up to 70 years after death. Exceptions include news, satire, scholarship, documentaries, and fleeting appearances.
AI content transparency (broader than deepfakes)
SB 942 — California AI Transparency Act
Applies to “covered providers” of generative AI systems publicly accessible in California with 1 million or more monthly visitors or users. Requires:
- A free, public AI detection tool that lets users assess whether content was created or altered by the provider’s GenAI system.
- Latent and manifest watermarks on AI-generated content that are “extraordinarily difficult” to remove.
- Contractual obligations on third-party licensees to maintain watermarking; if the provider learns a licensee has disabled watermarking, it must revoke the license within 96 hours.
Penalties: $5,000 per violation per day for non-compliance.

AB 2013 — AI training data transparency
Requires developers of generative AI systems to publicly disclose summary information about the datasets used to train their models. Not deepfake-specific but relevant for any provider whose AI generates synthetic media.
Federal overlay: the TAKE IT DOWN Act
Beyond California, the federal TAKE IT DOWN Act (signed in 2025, effective May 19, 2026) requires online platforms to remove non-consensual intimate imagery (including AI-generated) within 24 hours of a victim’s request. California platforms are subject to both regimes; the state laws are not preempted.
Compliance checklist for California operators
If your business creates, hosts, or distributes synthetic media reaching California users, before SB 942 takes effect on August 2, 2026:
- Inventory your AI surface area — identify every product or feature that generates, alters, or hosts synthetic media accessible to California users.
- Assess SB 942 applicability — if you have 1M+ monthly California users on a generative AI surface, you are a “covered provider.” Build the detection tool and watermarking now.
- Update content moderation for non-consensual intimate deepfakes and AI-generated CSAM. Ensure reporting flows comply with SB 981 and federal TAKE IT DOWN.
- Update entertainment contracts for any use of digital replicas to comply with AB 2602 and AB 1836.
- Pre-election audit — if you operate a platform with 1M+ California users, prepare your AB 2655 removal-and-labeling workflow at least 120 days before any California election.
- Document your compliance posture — California’s framework spans the AG’s office, district attorneys, the Labor Commissioner, and private rights of action. Multi-source enforcement means audit trails matter.
Frequently asked questions
Are deepfakes illegal in California?
It depends on the deepfake. Non-consensual sexual deepfakes are criminal under Penal Code § 647(j)(4) and SB 926, and civilly actionable under Civil Code § 1708.8 (as expanded by AB 621). AI-generated child sexual abuse material is criminal under AB 1831. Election deepfakes are subject to disclosure (AB 2355) and platform removal (AB 2655) requirements; the prohibition on materially deceptive election content (AB 2839) is currently enjoined on First Amendment grounds. Non-sexual, non-election deepfakes are not categorically illegal but may be actionable under existing torts (defamation, right of publicity, fraud).
What are the penalties for deepfakes in California?
Civil penalties for non-consensual sexual deepfakes are up to $50,000 (or $250,000 with malice) under AB 621. Criminal penalties under Penal Code § 647(j)(4) start at up to 6 months in county jail and a $1,000 fine for a misdemeanor; up to 364 days and $2,000 if the victim was a minor; felony charges are possible for repeat offenses involving minors. SB 942 imposes $5,000 per violation per day on covered AI providers that fail to comply with detection-tool and watermarking duties.
When does SB 942 (the California AI Transparency Act) take effect?
August 2, 2026. The original effective date was January 1, 2026, but AB 853 delayed implementation to August 2, 2026.
Who enforces California deepfake laws?
Enforcement is multi-source. The California Attorney General enforces SB 926 and platform duties. District attorneys prosecute Penal Code § 647(j)(4) and AB 1831 cases. The Labor Commissioner enforces AB 2602 (digital replicas in entertainment contracts). Several statutes (AB 621, SB 926, AB 1836, AB 2655) provide private rights of action that let victims and their estates sue directly.
Does California have an election deepfake ban?
Partially. AB 2839 prohibits knowingly distributing materially deceptive election content with malice within 120 days of an election, but a federal court preliminarily enjoined the law in 2024 on First Amendment grounds. AB 2655 (platform removal duty) and AB 2355 (mandatory AI disclosure on political ads) remain in force.
