Copilot Legal Privilege Review Workflow
Attorney-client privilege + work-product doctrine + Copilot summarization is a preventable-waiver risk. This is the EPC Group workflow that closes it.
Frequently Asked Questions
Why does Copilot need a legal privilege review workflow?
Two reasons. (1) Attorney-client privilege can be waived if privileged content is summarized by Copilot and the summary flows to a non-privileged recipient. Copilot semantic index reaches every SharePoint site the user has read access to — including sites containing privileged material. Without a labeling + DLP overlay, an in-house attorney's Copilot summary can inadvertently disclose privileged content to a business user. (2) Work-product doctrine protects material prepared in anticipation of litigation. Copilot-generated summaries of litigation-related content need the same protection classification as the underlying work product to preserve the doctrine's coverage.
What is the labeling taxonomy for legal content?
Three legal-specific sensitivity labels layered on the standard 5-tier taxonomy. (1) Confidential — Attorney-Client Privileged — communications between attorney + client + covered agents. (2) Highly Confidential — Work Product — material prepared in anticipation of litigation (memos, discovery drafts, expert reports, opinions). (3) Confidential — Legal (non-privileged) — legal-team-authored content that is not privileged (published guidance, contracts under review, non-litigation memos). Auto-labeling policies apply based on: SharePoint site container (specific legal team sites default to privileged), keyword patterns (attorney-client, work product, prepared for litigation), and manual attorney designation on new documents.
What DLP for Copilot policies apply?
Two policies. (1) BLOCK — Copilot cannot summarize or return content labeled Confidential — Attorney-Client Privileged. Not just downstream disclosure to non-privileged users — the summarization itself is blocked to prevent the labeled content from being restated in a form that might leak. (2) BLOCK OR RESTRICT — content labeled Highly Confidential — Work Product is blocked from Copilot summarization by users outside the litigation matter team. Users in the litigation team can summarize but the summary output is auto-labeled with the same work-product designation. The DLP policies produce the paper trail that supports privilege + work-product claims in the event of a challenge.
How does legal hold work with Copilot?
Copilot activity is preserved by Purview eDiscovery Premium legal hold (see /answers/purview-ediscovery-premium-deployment). When the General Counsel places a matter on legal hold, custodians on the hold have their subsequent Copilot activity captured — prompts, responses, citations. This means: (1) Copilot conversations are eDiscoverable in the matter. (2) Deleting a Copilot conversation does not remove it from the hold. (3) Copilot activity that references privileged content is preserved AND retained under the privilege designation (privileged content stays privileged; the hold protects it from deletion, not from privilege).
What does the General Counsel workflow look like?
Weekly: GC or designee reviews Copilot DLP events in the labeled legal content. Monthly: legal team + IT + Compliance meet on any DLP incidents + labeling gaps + hold status changes. Quarterly: privilege audit — sample Copilot conversations from labeled-legal-site users, verify no privilege waivers occurred. Annually: refresh the labeling taxonomy against new case law + new firm practice areas. EPC Group's legal-vertical Copilot engagement produces the full workflow document + GC reporting template.
What does an EPC Group legal-vertical Copilot engagement produce?
Standard 30-Day Copilot Readiness Accelerator plus five legal-specific deliverables: (1) 3-tier legal sensitivity label taxonomy. (2) Auto-labeling policies (site container + keyword + manual attorney designation). (3) DLP for Copilot policies covering attorney-client + work product. (4) eDiscovery Premium legal hold integration with GC workflow. (5) General Counsel weekly / monthly / quarterly / annual review cadence + reporting template.
