California enacts first law governing generative AI use by lawyers and arbitrators
California has become the first state to pass a law on generative AI use by lawyers and arbitrators. Reports say firms must prepare for 2027, and legal commentary suggests the end of the "the AI did it" excuse.
Who is affected and how
- lawyer
- Checking AI-assisted filings and research remains the lawyer's own responsibility, and this should be documented in the firm's workflow.
- corporate lawyer
- Internal AI-use policies and expectations for outside advisers' AI use should be aligned with the California rules.
- compliance specialist
- The firm's AI toolset and training programme should be reviewed before the rules take effect in 2027.
