California Moves to Require AI Disclosure in Court Filings
State lawmakers pass first-in-the-nation bill mandating attorneys reveal generative AI use as bar association weighs parallel ethics rules.
California is advancing two parallel efforts to regulate how attorneys use artificial intelligence in legal practice, responding to mounting concerns about AI-generated errors appearing in court filings.
The state legislature passed Senate Bill 574 on September 2, 2026, establishing what supporters describe as the nation's first law requiring attorneys to disclose when they use ChatGPT or other generative AI platforms to produce court documents. The bill now awaits Governor Gavin Newsom's signature.
What the legislation requires
Under SB 574, attorneys must verify the accuracy of all AI-generated information before filing it with courts. The bill also prohibits lawyers from entering confidential client information into public AI platforms—a practice that could expose privileged material or violate data protection obligations.
The disclosure requirement represents a significant shift in transparency standards. Rather than allowing silent AI use, the law would force attorneys to affirmatively state when generative tools contributed to their work product.
Parallel ethics rule changes
Simultaneously, the State Bar of California's Standing Committee on Professional Responsibility and Conduct has proposed amendments to the state's Rules of Professional Conduct addressing AI use. The committee was scheduled to consider the new rule language on September 11, according to Law.com, which first reported these developments.
The proposed ethics rules would mandate citation verification in pleadings and require attorneys to inform clients about AI use in certain circumstances. These requirements would operate alongside SB 574's court-focused disclosure mandates, creating a dual-layer regulatory framework.
Why it matters
California's dual-track approach—combining statutory law with professional conduct rules—could become a template for other states grappling with AI adoption in legal practice. The legislation acknowledges that existing competence and diligence requirements may not adequately address generative AI's unique risks, particularly its tendency to fabricate citations and case law. For legal technology vendors and law firms, California's framework signals that AI transparency and verification protocols are shifting from best practices to legal obligations. The state's large legal market means compliance requirements developed here often influence national standards.
Rising error concerns
Both initiatives stem from what lawmakers and bar leaders characterize as a continued rise in error-riddled filings containing AI-generated content. Courts nationwide have documented cases where attorneys submitted briefs citing non-existent cases or misrepresenting legal precedent—errors traced to generative AI tools that produce plausible-sounding but factually incorrect content.
The California measures attempt to address these failures through mandatory verification steps and transparency requirements that make AI use visible to courts and clients.
