California SB 574: New AI Requirements for Lawyers and Why Verifiable Legal AI Matters

California has enacted new requirements for attorneys using artificial intelligence, and the implications extend well beyond the courtroom.

California Senate Bill 574 (SB 574), effective January 1, 2027, establishes express obligations relating to AI-generated information, verification, confidentiality, and professional judgment. The central principle is familiar: attorneys must be able to verify the information on which they rely.

For legal professionals using AI to research legal questions, draft agreements, review contracts, and evaluate market standards, this raises an important question: should lawyers simply trust AI-generated answers, or should AI help them independently verify those answers?

At SimpleDocs, we believe the answer is clear.

What Is California SB 574?

California SB 574 establishes requirements for attorneys using generative artificial intelligence in legal practice. The legislation adds Business and Professions Code Section 6068.1 and amends Code of Civil Procedure Section 128.7, among other provisions. It does not prohibit legal AI. Instead, it reinforces attorney accountability, source verification, confidentiality, and independent professional judgment.

Several obligations apply to lawyers generally—not only litigators. In-house counsel, transactional attorneys, and commercial lawyers therefore have reason to review their AI practices.

What Does California SB 574 Require of Lawyers?

1. Verify AI-generated information

Attorneys using generative AI must take reasonable steps to verify the accuracy of its outputs, including legal citations, and correct erroneous or hallucinated information in materials they use. An AI system may describe an indemnification clause as unusually broad or a liability cap as market standard. But which sources support that characterization? Can the attorney inspect them? A recommendation is not a substitute for the evidence supporting it.

2. Personally verify citations in covered court filings

The law also amends Section 128.7 to require personal verification of citations in covered court filings, including citations generated by AI. An apparently plausible citation may refer to a nonexistent case, misstate a holding, or inaccurately describe authority. Lawyers remain responsible for checking the actual source.

3. Retain independent legal judgment

Attorneys cannot delegate the practice of law to generative AI. AI can accelerate drafting, research, and analysis, but professional decisions and the final work product remain the lawyer's responsibility.

4. Protect confidential information

The statute restricts entry of confidential, personally identifying, and other nonpublic information into AI systems unless access is appropriately limited to authorized persons subject to confidentiality obligations. Vendor terms, access controls, and data-handling practices therefore belong in legal AI evaluations.

5. Consider applicable disclosure requirements

The law also requires attorneys to disclose the use of generative AI in documents submitted to a court, and to consider whether to disclose its use in content provided to the public. Legal teams should review the statutory text and any applicable court rules rather than assuming a single disclosure practice fits every use.

Why This Matters for In-House Legal Teams

Much of the discussion of AI hallucinations has centered on fabricated case citations. But verification matters just as much in everyday contract work.

An in-house lawyer may ask AI whether a proposed limitation of liability is consistent with market practice, whether an NDA contains unusual confidentiality language, or how similar companies structure indemnification obligations. The answer may sound persuasive. The harder question is whether it reflects actual contracts or merely the model's prediction of plausible language.

This is where verifiable contractual sources become valuable.

The Difference Between AI Answers and Verifiable Legal AI

Consider a lawyer asking: “What is a typical limitation of liability provision in an enterprise software agreement?”

An AI assistant may say that liability is commonly capped at twelve months of fees. That may be a useful starting point, but it is not the end of the analysis. Which agreements support that conclusion? What industries do they represent? Are the parties comparable? What exceptions apply for confidentiality breaches, indemnities, or misconduct?

Verifiable legal AI should make it easier to move from a generated conclusion to the underlying evidence.

How SimpleDocs Supports Verifiable Legal AI

SimpleDocs combines AI-powered contract review and drafting with access to contract precedent through Law Insider. Law Insider's extensive collection of publicly available contracts and clauses provides a foundation of real-world language that attorneys can inspect and evaluate.

Real contracts, not just generated language

Contract drafting depends on context. With SimpleDocs and Law Insider's contract data, attorneys researching indemnification, termination rights, restrictive covenants, or liability caps can examine contractual precedents rather than relying solely on AI-generated descriptions.

A precedent is not automatically appropriate for a new transaction. But the ability to inspect real agreements gives attorneys evidence they can evaluate independently.

AI-powered contract research and analysis

SimpleDocs brings AI-powered review and drafting into lawyers' contract workflows, while Law Insider's contract data supports research into comparable provisions and alternative language. The objective is not to replace judgment but to accelerate the work leading to an informed judgment.

Citations and source verification

There is a critical difference between an AI system producing a citation and a user being able to open the cited source and determine whether it supports the claim.

Law Insider's contract database, available as a source of contract precedent within the SimpleDocs ecosystem, makes underlying agreements and clauses accessible for independent review. Attorneys can evaluate what the source actually says and whether it is relevant to their matter.

Contractual precedent and binding legal authority are not interchangeable. A publicly available commercial agreement can illuminate drafting practice; it does not establish what the law requires. Likewise, a link to a source does not guarantee that an AI-generated characterization of that source is accurate.

Our goal is not to replace verification. It is to make verification easier.

Why Source Verification Should Be Part of the Workflow

Verification should not require a lawyer to start the research process over after receiving an AI answer. The better experience connects AI recommendations to the underlying materials and allows lawyers to move naturally between analysis, source inspection, and drafting.

Legal AI should help attorneys identify source language, inspect agreements in context, compare alternatives, and retain control of the final document. That is the direction we believe legal AI needs to move.

Enterprise Security and Confidentiality Matter Too

SB 574 also highlights the need to protect sensitive client and business information. Commercial agreements often contain confidential pricing, financial terms, personal information, and proprietary strategies.

SimpleDocs is an enterprise legal technology platform that brings together AI-powered contract workflows and Law Insider's contract intelligence. The broader enterprise offering includes SOC 2 Type II controls, contractual commitments not to train AI models on customer data, and enterprise access-management capabilities.

These are important considerations in a vendor review. No security certification or vendor promise alone establishes an attorney's compliance with SB 574; organizations must evaluate the actual system, use case, and confidentiality requirements.

What Should Legal Teams Do Before January 1, 2027?

Review the AI tools currently used for research, drafting, and contract analysis. Establish processes to check AI-generated claims and citations. Evaluate vendor confidentiality terms and access controls. Determine whether tools expose the underlying sources needed to evaluate outputs. Train attorneys on verification, judgment, and disclosure responsibilities. For litigation, establish specific procedures for court-filed citations and disclosures.

The Future of Legal AI Is Verifiable

The first wave of legal AI focused on what systems could generate: drafts, summaries, redlines, and research answers. Those capabilities are increasingly common.

The next challenge is making the work more reliable, transparent, and useful to the attorneys responsible for it.

That requires more than sophisticated language models. It requires access to real sources, careful product design, appropriate security protections, and workflows that preserve professional judgment.

SimpleDocs draws on Law Insider's extensive collection of real contracts and clauses as a valuable foundation for source-informed contract work. By combining that data advantage with AI-powered review, drafting, and contract analysis, we're helping legal professionals work faster while retaining the ability to examine the information behind their decisions.

The future of legal AI isn't simply about generating better answers. It's about making those answers easier to verify.
