TL;DR:
California passed Senate Bill 574 on August 31, 2026, creating the nation’s first integrated set of rules governing how lawyers, arbitrators, judicial officers, and ADR providers may use generative AI in legal practice. Governor Newsom signed the measure into law on September 30, 2026. The statute bans delegating the practice of law to AI, requires verification of AI outputs (including every citation), bars entering confidential information into unrestricted AI tools, and imposes disclosure obligations to the court for AI-generated content in filings. Violations can trigger sanctions under state ethics and civil procedures. The law also directs the Judicial Council to revise AI guidance for courts and ADR processes. For California trial teams, the development demands new workflows around AI usage, citation verification, and transparency in filings. Objection Academy can support practice-ready training on evidence application and courtroom objections in light of these guardrails.
California’s landmark SB 574 codifies a protective framework for AI use in litigation, changing daily practice for many California lawyers and ADR participants. The measure, introduced to address rapid AI adoption in lawyering, was approved by both houses on August 31, 2026, and enrolled shortly thereafter. Bloomberg Law reports that Gov. Newsom signed the bill into law on September 30, 2026, marking a decisive shift in attorney ethics and litigation workflow. The statute draws on existing judicial council guidance while expanding the formal duties that practicing attorneys must observe when engaging AI tools in filings and advocacy.

TL;DR: The core legal shift and its practical impact
- SB 574 bans attorneys from delegating the practice of law to generative AI tools and prohibits entering confidential or nonpublic information into AI systems unless appropriate safeguards apply. It requires human attorney involvement and oversight in AI-assisted work. (sullcrom.com)
- Attorneys must verify AI outputs, including all case and statutory citations, and correct any errors or hallucinations before use in court submissions. For any court filing, at least one attorney must sign in their own name. (sullcrom.com)
- When AI is used to prepare or contribute to court filings or materials intended for public view, the use must be disclosed to the court, and the court’s standards may require additional disclosures or certifications. (sullcrom.com)
- ADR providers and arbitrators are also subject to constraints on relying on AI or delegating decision-making to AI tools, with transparency requirements when AI is involved. (sullcrom.com)
- The bill directs the Judicial Council to revisit and revise its AI-related standards and to expand oversight mechanisms in relation to ADR processes. (sullcrom.com)
- For practicing litigators, the practical implications include rethinking document drafting, evidence presentation, and discovery practices to align with verified AI outputs and court disclosure requirements. (news.bloomberglaw.com)
What SB 574 does and why it matters for trial lawyers
SB 574 represents a nationwide first in legislating the use of generative AI in the practice of law within a single state. Its essential design is twofold: (1) constrain how AI may be used to perform or assist with legal work, and (2) establish concrete duties around verification and disclosure to courts. The bill text and accompanying summaries describe prohibitions on delegating substantive legal work to AI, restrictions on inputting confidential information into AI systems, and a requirement that outputs be personally verified by a human attorney prior to use in filings. It further requires attorneys to disclose AI use to the court when presenting AI-generated content, with sanctions potential for violations under state ethics rules and civil procedure standards. The legislation also extends similar guardrails to arbitrators and ADR providers, ensuring a consistent governance framework across the litigation lifecycle. (sullcrom.com)
The status timeline is clear: enactment occurred as part of the 2025–2026 session, with passage on August 31, 2026, enrollment in early September 2026, and the governor’s signature on September 30, 2026. Bloomberg Law’s coverage confirms the signing date and emphasizes that SB 574 codifies and expands on existing California court rules governing AI use by lawyers and arbitrators. This is a meaningful milestone for California practitioners and for the broader trend of professional responsibility in the AI era. (news.bloomberglaw.com)
Practical implications for California trial teams
- Filings and citations: Each court filing containing AI-generated content or AI-assisted drafting will require careful verification of every citation, as the bill emphasizes accuracy and prohibits reliance on unverified AI outputs. Lawyers should implement a verification checkpoint for citations before submission. (sullcrom.com)
- Professional responsibility: The law reinforces the obligation that a responsible attorney remain personally involved in substantive work and in the authentication of materials submitted to the court. This shifts some workflows away from “AI-first” drafting toward a curated, attorney-verified process. (sullcrom.com)
- Confidential information and data governance: Restrictions on inputting confidential or nonpublic information into AI tools necessitate tightened data governance, including clear guidelines on which tools may be used, where data is stored, and how access is controlled. Firms may need secure, compliant AI ecosystems or vendor contracts that address confidentiality and data handling. (sullcrom.com)
- Disclosure and strategy: The court-disclosure requirement means trial teams must be ready to explain how AI contributed to a filing and to demonstrate the steps taken to ensure accuracy. This has downstream implications for motions practice, voir dire, and evidentiary issues where AI-derived materials or prompts might be at issue. (news.bloomberglaw.com)
- ADR and arbitration: The rules extend to ADR participants, potentially affecting how arbitration briefs, awards, and related submissions are prepared and reviewed. Practitioners should anticipate the need to document AI-assisted processes and avoid reliance on AI to the extent prohibited. (sullcrom.com)
- Sanctions risk: Violations can trigger sanctions under state ethics rules and CCP provisions, underscoring the importance of robust internal review protocols and audit trails for any AI-assisted work. Firms should build clear escalation and quality-control steps into their workflow. (sullcrom.com)
How to operationalize SB 574 compliance today
- Establish an AI governance policy: Create a policy that specifies which tools are permitted for which tasks, how data is handled, and who signs off on AI-assisted filings. Include a mandatory citation-verification checklist and a note field for AI disclosure in filings.
- Build a verification workflow: Implement a standardized review process where at least one attorney signs off on AI-assisted content and verifies every citation before filing. This aligns with SB 574’s emphasis on personal responsibility and verified outputs. (sullcrom.com)
- Train teams on disclosure duties: Prepare model disclosures and practical talking points explaining how AI contributed to a filing, tailored to CA courts’ expectations and the new statutory framework. Consider using practice simulations to rehearse these disclosures under different courtroom scenarios.
- Leverage training tools for readiness: Objection Academy offers dedicated, drill-driven training that emphasizes objection handling, evidence literacy, and courtroom readiness.
