Harvey reached an $8 billion valuation. eDiscovery AI adoption went from 19% to 79% in one year. Governance is 25%, but bar associations and courts are setting rules faster than firms can implement them. The Texas Order on AI, the Southern District of New York's attestation requirement, and state bar ethics opinions under Model Rules 1.1 (competence), 1.6 (confidentiality), and 5.3 (supervisory responsibility) all converge on one point: the attorney remains personally responsible for AI-generated work product. When opposing counsel files a Daubert challenge against an AI-assisted brief or an ethics board investigates an AI-drafted filing, producing the provenance chain from research query to final output is the minimum defensible response. "The tool generated it" is not sufficient under any bar association's current guidance.
This industry includes 3 segments in the Ontic governance matrix, spanning risk categories from Category 1 — Assistive through 3_evidentiary. AI adoption index: 5/5.
Legal - Regulatory Landscape
The legal sector is subject to 11 regulatory frameworks and standards across its segments:
- Client confidentiality obligations
- Cross-border: GDPR, legal professional privilege
- Federal Rules of Civil Procedure
- Federal Rules of Evidence
- Federal/state rules of civil procedure
- Multi-jurisdiction bar ethics rules
- Rules of evidence
- Sedona Principles (e-discovery)
- State UPL statutes
- State bar ethics rules (Model Rules 1.1, 1.6, 3.3, 5.3)
- State bar ethics rules (Model Rules 1.1, 1.6, 5.3)
The specific frameworks that apply depend on the segment and scale of deployment. Cross-industry frameworks (GDPR, ISO 27001, EU AI Act) may apply in addition to sector-specific regulation.
Legal - Legal -- Solo / Boutique
Risk Category: Category 1 — Assistive Scale: SMB Applicable Frameworks: State bar ethics rules (Model Rules 1.1, 1.6, 5.3), Client confidentiality obligations, State UPL statutes
The bar association does not distinguish between the attorney's work and the model's.
The Governance Challenge
Solo and boutique firms use AI for contract drafting, research summarization, and client intake triage. The productivity gain is significant for resource- constrained practices. Model Rules 1.1 (competence), 1.6 (confidentiality), and 5.3 (supervisory responsibility) all apply to AI-assisted work product. State bar ethics opinions are proliferating — most require that the attorney can explain and defend any AI-generated output as if they wrote it. Most solo practitioners cannot reconstruct the provenance of their AI-assisted work.
Regulatory Application
State bar ethics rules are the primary governance framework. Model Rule 1.1 requires competence in understanding AI tools. Model Rule 1.6 requires that client confidentiality is maintained in AI systems. Model Rule 5.3 requires supervision of AI as a non-lawyer assistant. State UPL statutes apply to AI outputs that constitute legal advice without attorney oversight.
AI Deployment Environments
- Studio: Contract / brief drafting assist | Research summarization | Client intake triage
- Refinery: Engagement letter / fee disclosure governance | Standard template enforcement
Typical deployment path: Studio → Studio → Refinery
Evidence
- eDiscovery AI adoption went from 19% to 79% in one year
- 25+ state bar associations have issued AI ethics opinions
- SDNY attestation requirement applies to all AI-assisted filings
Legal - Legal -- Regional Firm
Risk Category: 3_evidentiary Scale: Mid-Market Applicable Frameworks: State bar ethics rules (Model Rules 1.1, 1.6, 3.3, 5.3), Federal/state rules of civil procedure, Rules of evidence, State UPL statutes, Client confidentiality obligations
Opposing counsel will examine the provenance of every AI-assisted brief. The evidence chain must exist before the challenge.
The Governance Challenge
Regional law firms deploy AI for brief drafting, cite-checking, discovery search, client-facing legal analysis, regulatory compliance opinions, and discovery document review. Model Rules 1.1 (competence), 1.6 (confidentiality), 3.3 (candor to the tribunal), and 5.3 (supervisory responsibility) apply to every AI-assisted work product. Federal and state rules of civil procedure and rules of evidence govern the admissibility of AI-assisted legal analysis. When opposing counsel challenges the provenance of an AI-assisted filing under Rule 11, or an ethics board investigates an AI-drafted work product, the firm must produce the complete chain from research query to final output.
Regulatory Application
State bar ethics rules (Model Rules 1.1, 1.6, 3.3, 5.3) govern AI-assisted legal work. Federal and state rules of civil procedure govern AI-assisted discovery and filings. Rules of evidence govern admissibility of AI-assisted analysis. State UPL statutes apply to AI outputs constituting legal advice without attorney supervision. Client confidentiality obligations extend to AI systems processing privileged material.
AI Deployment Environments
- Studio: Brief drafting & cite-checking | Discovery search copilots
- Refinery: Client-facing legal analysis | Regulatory compliance opinions | Discovery document review
- Clean Room: Internal investigation bundles | Pre-litigation risk assessment files
Typical deployment path: Refinery → Refinery → Clean Room
Evidence
- Several SDNY judges' standing orders require attorneys to disclose and certify AI use in filings
- 25+ state bar associations have issued AI ethics opinions
- Daubert challenges to AI-generated expert analyses and Rule 11 scrutiny of AI-assisted filings are emerging
- In our research, eDiscovery AI adoption rose from 19% to 79% in a single year
Legal - Legal -- Am Law 50 / Big Four
Risk Category: 3_evidentiary Scale: Enterprise Applicable Frameworks: Multi-jurisdiction bar ethics rules, Federal Rules of Civil Procedure, Federal Rules of Evidence, Sedona Principles (e-discovery), Cross-border: GDPR, legal professional privilege
When the firm audits clients' AI governance, it must first be able to demonstrate its own.
The Governance Challenge
Am Law 50 firms and Big Four legal practices deploy AI for internal memo drafting, knowledge management, multi-jurisdiction compliance analyses, audit workpaper generation, litigation hold governance, and regulatory examination preparation. Multi-jurisdiction bar ethics rules create compound supervisory obligations. Sedona Principles govern AI-assisted e-discovery. Cross-border operations add GDPR and legal professional privilege requirements. The structural irony is acute: firms advising clients on AI governance must demonstrate their own. When a court examines whether AI-assisted work product meets admissibility standards, the firm's credibility depends on its own governance infrastructure.
Regulatory Application
Multi-jurisdiction bar ethics rules create compound obligations — a single matter may trigger ethics rules in multiple states. Federal Rules of Civil Procedure govern AI-assisted litigation. Federal Rules of Evidence govern admissibility of AI-assisted analysis and work product. Sedona Principles govern AI-assisted e-discovery protocols. Cross-border operations trigger GDPR data processing requirements and legal professional privilege frameworks that vary by jurisdiction.
AI Deployment Environments
- Studio: Internal memo drafting | Knowledge management copilots
- Refinery: Multi-jurisdiction compliance analyses | Audit workpaper generation
- Clean Room: Litigation hold governance | Court-admissible AI output | Regulatory examination prep
Typical deployment path: Clean Room → clean_room (primary) | refinery for practice-level governance
Evidence
- Big Four have announced more than $20B in combined AI investments over multi-year programs — governance must match investment
- Courts are beginning to examine AI-assisted work product admissibility
- Multi-jurisdiction ethics compliance is compounding with AI adoption
- Client expectations for law firm AI governance are increasing
