American Lawyer: Clients Are Asking Law Firms for Their Data Back — Threat or Opportunity?

The American Lawyer published (August 3) a dedicated piece on a new procurement dynamic: some corporate clients are asking law firms to compile and return their historical matter data. The driving force is AI: clients want to run their own AI analysis across years of matter history, billing data, and work product — to decide which matters to insource, which categories to automate, and which outside relationships to retain or cut. The American Lawyer frames this as both a risk (clients who get their data and run AI analysis may accelerate insourcing decisions) and an opportunity (firms that proactively structure and return client data demonstrate transparency and competence, building client stickiness). For law firm BD directors and managing partners: the data-return request is an early signal of what the insourcing analysis described by GC commentators (running AI against years of invoice narratives) looks like when it goes formal. Firms that have structured data for clients — matter analytics, AI-disclosed billing, outcome tracking — are in a stronger position to control the narrative of that analysis. The opportunity framing is real: a firm that proactively shares structured matter intelligence with clients before they ask for it is demonstrating the kind of commercial relationship behaviour that Thomson Reuters found is now a top driver of client favourability.
