Summary
As of September 9, 2026, California Assembly Bill 1831 (Chapter 926, Statutes of 2024) is in force. Introduced by Assemblymember Marc Berman on January 12, 2024, the bill was passed by the California Legislature, approved by Governor Gavin Newsom on September 29, 2024, and chaptered by the Secretary of State on September 29, 2024. The Act became operative on January 1, 2025, following the fulfillment of its contingent enactment condition regarding Senate Bill 1381.
The Act amends Sections 311, 311.2, 311.11, and 311.12 of the California Penal Code to explicitly expand the definition of obscene matter and child sexual abuse material to cover content generated or modified using artificial intelligence or digital alteration. By doing so, California law closes a legal loophole that previously required proof of a real minor's involvement, bringing synthetic and deepfake sexual depictions of minors under the same criminal prohibitions as traditional child sexual abuse material.
Enforcement of AB 1831 is carried out by California district attorneys, municipal police departments, county sheriffs, and the California Department of Justice. These law enforcement and prosecutorial authorities are empowered to investigate, arrest, and prosecute individuals who knowingly create, produce, duplicate, distribute, exchange, or possess AI-generated child sexual abuse material.
Violations of the amended Penal Code sections are punishable as misdemeanors or felonies depending on the specific offense and prior criminal record. Criminal courts may impose penalties including imprisonment in county jail or state prison for up to six years, fines reaching up to $100,000, and mandatory sex offender registration under California Penal Code Section 290.

California Assembly Bill 1831, officially designated as Chapter 926, Statutes of 2024, represents a landmark legislative effort to combat the proliferation of artificial intelligence-generated Child Sexual Abuse Material (CSAM). Enacted on September 29, 2024, this legislation directly addresses the emerging challenges posed by advanced AI technologies that can create disturbing and harmful content resembling actual children. The primary objective of AB 1831 is to amend various sections of the California Penal Code to explicitly include digitally altered or AI-generated content within the existing prohibitions against child pornography.
Prior to the enactment of AB 1831, a significant legal loophole existed wherein the creation, distribution, or possession of AI-generated CSAM was difficult to prosecute under California law, as existing statutes often required the depiction of a 'real' child. This legislative gap allowed perpetrators to exploit AI to produce virtually indistinguishable deepfake CSAM, thereby evading justice and perpetuating the sexual exploitation of children. AB 1831 was introduced by Assemblymember Marc Berman and garnered bipartisan support, reflecting a broad consensus on the urgent need to update legal frameworks in response to technological advancements. It became operative following the enactment of Senate Bill 1381 by January 1, 2025, ensuring its full legal effect.
Definitions
Central to California AB 1831 are key definitional expansions that integrate artificial intelligence into existing legal terminology concerning child sexual abuse material. The Act amends the Penal Code to include "matter generated through the use of artificial intelligence." This term is defined as an image that has been generated or modified by a machine-based system that can, for a given set of human-defined objectives, create visual content that is, or would falsely appear to a reasonable person to be, or to incorporate, actual photographs or recordings of a real human being actually engaging in the actions depicted. This broad definition ensures that various forms of AI-created or AI-manipulated content fall under the purview of the law.
Furthermore, the Act clarifies and expands the definition of "depicts a person under 18 years of age personally engaging in or simulating sexual conduct." As it pertains to obscene matter, this now explicitly includes a representation of a real or fictitious person created through the use of artificially intelligent software or computer-generated means, who is, or who a reasonable person would regard as being, a real person under 18 years of age, engaging in or simulating sexual conduct. This crucial amendment directly targets deepfake technology, ensuring that even if a depiction does not involve a real child in its creation, its realistic appearance of a minor engaging in sexual conduct renders it illegal. The legislative intent emphasizes that the harm caused by CSAM exists regardless of how it is produced, whether through traditional means or advanced AI.
Governance and Institutional Framework
The governance and institutional framework for California AB 1831 primarily involves the legislative, executive, and judicial branches of the California state government, with a significant role for state and local law enforcement agencies. The California Legislature, through the authorship of Assemblymember Marc Berman and the collaborative efforts of numerous co-authors and legislative committees, was responsible for drafting, debating, and ultimately passing the bill. Governor Gavin Newsom's signature on September 29, 2024, officially enacted AB 1831 into law, making it Chapter 926 of the Statutes of 2024.
Enforcement of the amended Penal Code sections falls primarily to California's district attorneys and local law enforcement agencies. These entities are now empowered with updated legal tools to investigate, prosecute, and penalize individuals involved in the creation, distribution, or possession of AI-generated CSAM. The Ventura County District Attorney's Office, for instance, was a co-sponsor of the bill, highlighting the active involvement of prosecutorial bodies in advocating for and implementing this legislation. The judicial system will interpret and apply these new provisions, ensuring that legal precedents align with the legislative intent to protect children from AI-enabled exploitation. The bill's expansion of existing crimes also imposes a state-mandated local program, requiring the state to reimburse local agencies and school districts for certain associated costs, thus integrating local government into the broader enforcement framework.
Key Focus Areas
California AB 1831 focuses on several critical areas to address the threat of AI-generated Child Sexual Abuse Material. A primary focus is the explicit expansion of existing child pornography laws to encompass content created or manipulated using artificial intelligence. This directly closes a loophole that previously allowed perpetrators to create highly realistic, sexually exploitative images of children without facing the same legal consequences as those who produced traditional CSAM. The legislation ensures that the medium of creation does not diminish the severity of the crime or the harm caused to children.
Another key area is the criminalization of the entire lifecycle of AI-generated CSAM, including its creation, distribution, and possession. By amending Penal Code Sections 311, 311.2, 311.11, and 311.12, the Act establishes clear legal prohibitions across all stages of engagement with such illicit material. The bill also emphasizes the inherent harm of AI-generated CSAM, noting that AI programs are often trained using existing real images of child abuse, thereby re-victimizing actual children. This legislative stance underscores that the use of AI in this context is not a victimless crime and poses significant dangers to children's physical and psychological well-being.
Implementation Framework
The implementation framework for California AB 1831 is designed to seamlessly integrate the new provisions into the existing legal landscape of California's Penal Code. The Act achieves this by directly amending specific sections, including 311, 311.2, 311.11, and 311.12, which already address various aspects of child pornography and sexual exploitation. This approach avoids creating entirely new legal structures but rather modernizes and expands the scope of established criminal statutes. The amendments ensure that the definitions of prohibited matter, representations of information, data, or images now explicitly include content that is "digitally altered or artificial-intelligence-generated."
A notable aspect of the implementation is the bill's provision for a state-mandated local program. By expanding the scope of an existing crime, AB 1831 imposes new duties or higher levels of service on local agencies and school districts, particularly in the realm of law enforcement and prosecution. Consequently, the California Constitution requires the state to reimburse these local entities for certain costs mandated by the state. This mechanism ensures that local governments have the necessary resources to enforce the updated laws. Furthermore, the Act's operative status was contingent upon the enactment of Senate Bill 1381 of the 2023–24 Regular Session taking effect on or before January 1, 2025, which has since occurred, confirming AB 1831's full legal force.
Monitoring and Evaluation
While California AB 1831 does not explicitly outline a formal, dedicated monitoring and evaluation framework within its text, the effectiveness of the Act will be implicitly assessed through established governmental processes and the ongoing efforts of various stakeholders. Law enforcement agencies, including district attorneys' offices and local police departments, will be responsible for tracking the incidence of crimes involving AI-generated CSAM, the number of investigations initiated, and successful prosecutions. This data will provide crucial insights into the prevalence of such offenses and the practical impact of the updated legal provisions. The legislative findings themselves emphasize the dynamic nature of technology and the need for laws to evolve, suggesting an inherent expectation of continuous review and adaptation.
Furthermore, advocacy groups, such as the Children's Advocacy Institute and Common Sense Media, which co-sponsored AB 1831, will likely continue to monitor the landscape of online child exploitation and the efficacy of legal protections. Their ongoing engagement and research can serve as an informal but vital mechanism for evaluating the Act's impact and identifying any new challenges that may arise with further technological advancements. The legislative process itself, including future bill analyses and committee hearings, provides opportunities for lawmakers to review the implementation and outcomes of AB 1831, allowing for potential amendments or further legislative action if deemed necessary to maintain robust child protection in the digital age.
Penalties, Liability, and Appeals
California AB 1831 significantly impacts penalties and liability by expanding the scope of existing criminal statutes to explicitly cover AI-generated Child Sexual Abuse Material. The Act amends sections of the Penal Code, such as 311.11, which pertains to the possession or control of child pornography. Consequently, individuals found guilty of creating, distributing, or possessing AI-generated CSAM will face the same severe felony penalties as those involved with traditional CSAM. These penalties can include imprisonment in state prison or county jail, substantial fines, or both, reflecting the state's determination to treat AI-enabled exploitation with the same gravity as other forms of child sexual abuse.
The bill's legislative counsel's digest explicitly states that by expanding the scope of an existing crime, the bill imposes a state-mandated local program, indicating that the legal and financial burden of prosecuting these offenses will be borne by local jurisdictions, with state reimbursement mechanisms in place. Liability extends to any person who knowingly engages in the prohibited acts, whether it involves the production, development, duplication, distribution, or possession of such material. The Act also addresses potential First Amendment challenges, with legislative findings asserting that the First Amendment does not protect obscenity, including child obscenity, even if created entirely by AI. The appeals process for convictions under these amended statutes would follow standard California criminal appellate procedures, allowing defendants to challenge legal errors or factual findings in higher courts.
Relationship to Other Instruments
California AB 1831 operates primarily by amending and expanding the scope of existing provisions within the California Penal Code, rather than creating an entirely new legal framework. Specifically, it modifies Sections 311, 311.2, 311.11, and 311.12, which are foundational statutes addressing various aspects of child pornography and sexual exploitation. This approach ensures that the new prohibitions against AI-generated CSAM are seamlessly integrated into California's established criminal law, leveraging existing enforcement mechanisms and judicial interpretations. The bill's legislative history also indicates that earlier drafts considered amendments to additional sections like 311.1, 311.3, 311.4, 311.5, 312, and 312.3, demonstrating a comprehensive review of related statutes.
The Act also explicitly acknowledges its relationship with federal law, noting that federal law already prohibits obscene visual representations of the sexual abuse of children, even if created without using a real child. This recognition underscores a broader alignment between state and federal efforts to combat child obscenity and exploitation, irrespective of the creation method. Furthermore, AB 1831's operative status was made contingent upon the enactment of Senate Bill 1381 of the 2023–24 Regular Session taking effect on or before January 1, 2025. This interdependency highlights a coordinated legislative strategy to address the complex challenges of AI and child protection, ensuring that complementary laws are in place for comprehensive coverage.
International Alignment
While California AB 1831 is a state-level law, its underlying principles and objectives align with broader international efforts to combat child sexual abuse and exploitation, particularly in the digital realm. The legislative findings within the Act emphasize that the sexual abuse of children is a serious crime repugnant to moral instincts, and that the prevention of sexual exploitation and abuse of children constitutes a government objective of paramount importance. This sentiment resonates with international treaties and conventions focused on child protection, such as the UN Convention on the Rights of the Child, which advocate for measures to protect children from all forms of sexual exploitation and abuse.
The global nature of the internet and AI technologies means that illicit content, including AI-generated CSAM, can originate and spread across borders. By proactively criminalizing such material, California is contributing to a global standard that seeks to eliminate the market for images of child sexual exploitation, regardless of their origin or creation method. This proactive legislative stance sets a precedent that can influence other jurisdictions grappling with similar issues, fostering a more robust international framework for safeguarding children online. The Act's recognition of federal law also implicitly connects it to the United States' international commitments in this area, as federal statutes often implement treaty obligations.
