AI Governance Is Now a Rule 5.1 Obligation — KM Must Build the Infrastructure

Intapp's analysis published August 14 frames AI governance as structurally equivalent to ethical wall program management — and documents why the analogy now has professional responsibility teeth. California's Committee on Professional Responsibility and Conduct approved in March 2026 a proposed amendment to Comment [1] of Rule 5.1 that would add governance of AI use to the internal policies managing partners must implement, alongside conflict checks, calendaring, and client funds. New York's court-wide AI certification rule took effect June 1. More than 35 state bars have issued AI guidance. For KM directors, the operational implication is that AI governance infrastructure — access controls, documented screen decisions, audit logs, and the ability to produce matter-level records in days rather than weeks — cannot be deferred to IT or risk management. Seventy-one percent of Fortune 500 general counsel already ask about AI use during panel negotiations; a firm that cannot answer with documented controls risks losing work to firms that can.
