California Is About to Pass the Strictest AI Law for Lawyers in the Country

California Is About to Pass the Strictest AI Law for Lawyers in the Country

A partner at a seven-attorney California litigation firm reviews her morning alerts on August 27. In the stack: California SB 574 is alive in the legislature with three days left in the session. The bill would make it illegal — under state law, not just ethics rules — for an attorney to delegate "the practice of law" to generative AI.

She's been using AI to draft initial briefs for the last six months. An attorney reviews every draft before it goes out. Is that delegation? The bill doesn't say.

That ambiguity is why SB 574 is the most consequential AI legislation for lawyers anywhere in the US right now — and why California law firm owners need to understand it before the session closes August 31.

SB 574 vs. COPRAC: Two Parallel Tracks, Two Different Consequences

If you've been following California's AI regulation story, you know about COPRAC — the California State Bar's Committee on Professional Responsibility and Conduct, which approved amendments to six Rules of Professional Conduct in March 2026. COPRAC governs attorney ethics. Violations lead to bar discipline: warnings, suspensions, disbarment.

SB 574 is something different. It's statutory law — legislation passed by the state legislature and codified in the California Business and Professions Code. Violating a statute governing your practice can mean civil liability, court sanctions, and loss of licensure — in addition to bar discipline.

California is about to have both. If SB 574 passes, an attorney who fails to verify a hallucinated AI citation doesn't just risk bar discipline under COPRAC Rule 3.3. They risk violating a statute. The exposure doubles.

The bill passed the California Senate unanimously — 39-0 — on January 29, 2026. It passed both chambers and was enrolled with Governor Newsom before the August 31, 2026 bill-passage deadline. The governor has until October 12, 2026 to sign or veto — 30 days from the Legislature's September 12 sine die adjournment. Implementation would likely take effect January 1, 2027.

The Four Things SB 574 Would Require of Attorneys

The bill creates four categories of obligations for California attorneys using generative AI:

1. Confidentiality — stop using consumer-grade AI for client data

Attorneys cannot input sensitive client information into public or consumer-grade AI systems. This includes Social Security numbers, dates of birth, driver's license numbers, and other personally identifying information. If your attorneys are using ChatGPT, Claude, or Gemini without a privacy-compliant enterprise subscription, and they're pasting client data into those tools, that's a violation under SB 574.

This isn't new as an ethical obligation — COPRAC already requires it. SB 574 makes it statutory.

2. Accuracy — you verify the output, not the tool

Attorneys must verify the accuracy of AI-generated material and correct any erroneous or hallucinated content before it goes anywhere: to a client, to opposing counsel, to a court. The verification obligation falls explicitly on the attorney. "The AI produced it" is not a defense.

3. Anti-discrimination — your AI outputs are your outputs

Attorneys must ensure their use of AI doesn't unlawfully discriminate based on protected characteristics — race, gender, age, disability status, and other federally or state-protected categories. If an AI tool produces a recommendation with disparate impact on a protected class, and you act on it, the legal exposure is yours.

4. Citation verification and disclosure

Attorneys must personally verify every citation in court filings. AI-generated citations cannot be submitted without the attorney having confirmed that each case exists, says what the brief claims it says, and is still good law. Westlaw or Lexis — not the AI — must be the verification source.

The bill also calls on attorneys to consider disclosing AI use in public-facing materials, framed as consideration rather than mandatory disclosure.

The "No Delegation" Clause: Where It Gets Complicated

The most consequential — and most ambiguous — provision in SB 574 is the prohibition against attorneys delegating "the practice of law to generative AI."

Unlike the four obligations above, which create a compliance framework, this is an absolute prohibition with no supervision allowance in the bill's current language. No amount of attorney review resolves the question if the AI itself is performing "the practice of law."

What is "the practice of law"? The bill doesn't define it. Courts have wrestled with that definition for decades across licensing disputes and unauthorized practice cases. The working definition in most states covers activities requiring legal judgment applied to specific client facts: legal research, drafting legal documents, advising on legal rights, representing clients in proceedings.

For a California law firm using AI to draft initial briefs, contracts, or discovery responses — with an attorney reviewing and signing off — the question is whether the AI is delegating the practice of law, or whether the attorney is using AI as a drafting tool that the attorney controls. That distinction is unresolved. Artificial Lawyer, writing about SB 574 on August 26, described the "no delegation" clause as potentially an "existential threat" to AI-native law firms that have built workflows around AI drafting with attorney review.

The California State Bar has separately issued summer 2026 guidance suggesting that judicial regulation — courts setting their own AI rules for proceedings before them — may be more appropriate than legislative action for this question. But if SB 574 becomes law, law firms won't be able to wait for judicial clarification.

For a firm that has built an AI-assisted drafting workflow: document it, understand where AI ends and attorney judgment begins, and get bar counsel input on whether your specific workflow could constitute delegation under a broad reading of this language.

The Arbitrator Restriction

SB 574 also covers arbitrators, who face a stricter version of the prohibition. Under the bill, arbitrators cannot permit AI to make or substantially influence procedural or substantive decisions. They must independently analyze evidence — not rely on algorithm-generated conclusions — and assume full responsibility for awards regardless of any AI assistance used.

For firms that participate in arbitration proceedings — employment, commercial, consumer arbitration — this matters not just for the arbitrators themselves but for how AI-generated materials submitted to arbitration will be received.

What the Timeline Looks Like

Date	What happens
August 31, 2026	California legislature adjourned — SB 574 enrolled
~October 12, 2026	Governor must sign or veto (30 days from adjournment)
January 1, 2027	Likely implementation date if signed

Update (August 31, 2026): SB 574 passed both chambers and was enrolled before session close. The governor's deadline is approximately October 12, 2026 — not September 30 as initially estimated. See California SB 574 Is on Newsom's Desk — What the October 12 Deadline Means for the full breakdown of what each outcome means.

If signed, California law firms have roughly three months to bring their workflows into compliance before January 1, 2027.

What California Firms Should Do Before August 31

Do not wait to see if the bill passes. Three moves now:

Document every AI workflow. Which tools are your attorneys using, for which tasks, and what does attorney review look like at each step? If SB 574 passes, you need to be able to show what work AI performs and demonstrate that attorneys exercise independent judgment over the output. Firms with documented workflows can demonstrate compliance; firms without them will be guessing.

Stop inputting sensitive client data into consumer-grade AI immediately. This is the clearest, least ambiguous obligation in the bill — and it's already required under COPRAC. If your attorneys are using free or personal AI accounts for client work, that stops now.

Establish a written citation verification protocol. Any AI-generated citation that goes into a court filing must be checked against Westlaw or Lexis by the signing attorney before submission. Write that protocol down, distribute it to every attorney and paralegal who touches litigation, and document that you're following it. The sanctions for skipping this step are already real and escalating — SB 574 would add a statutory violation on top of the bar discipline exposure.

What Out-of-State Firms Should Watch

SB 574 applies to California-licensed attorneys — not just California-based firms. If you're licensed in California and practicing anywhere in the country, it applies. If you're based in California without a California bar admission, it doesn't directly apply yet.

The more important signal is what California's passage would mean for other states. California has 260,000 licensed attorneys — the largest state bar in the US. When California moves on AI regulation, other states have historically followed within 12-24 months. New York, Texas, Florida, and Illinois have all been watching the California COPRAC process closely.

If SB 574 becomes law, it becomes the template for the first statutory AI regulation of attorneys in the US. The "no delegation" language will be litigated. The outcome of those cases will define how every state approaches the question of what role AI can legally play in legal practice.

For firms outside California: what passes or fails in Sacramento by August 31 sets the terms of the debate you will be having with your own state bar within two years.

One Action Before October 12

Update: The legislative session is complete — SB 574 is enrolled with Governor Newsom, who has until approximately October 12, 2026 to sign or veto. See California SB 574 Is on Newsom's Desk — What the October 12 Deadline Means for the current action steps.

California firm owners: draft a one-page AI workflow inventory if you haven't already. For each AI tool your attorneys use, write down (1) what task the tool performs, (2) at what point an attorney reviews and makes independent judgments about the output, and (3) whether any sensitive client data is entered. The "no delegation" question remains unresolved pending Newsom's decision — but documenting your current workflows is the right preparation either way.

Out-of-state firm owners: forward this to your bar counsel and ask one question — "Are you watching California SB 574, and what's our state's likely response if it's signed?" The answer tells you whether your firm is ahead of this curve or behind it.
