A View of How Language Models Will Transform Law

TL;DR

The paper explores how large language models could revolutionize the legal industry by increasing productivity, reducing costs, and shifting lawyers' roles towards more specialized, judgment-based tasks, potentially leading to sector consolidation.

Contribution

It presents a detailed analysis of the potential structural changes in the legal sector driven by LLMs, including economic impacts and evolving lawyer roles.

Findings

A 10% increase in attorney productivity could reduce associate headcount by 300-400 lawyers.

Cost savings from productivity gains could fund development of specialized LLMs.

Future legal work will focus more on judgment and nuanced tasks, with fewer lawyers needed overall.

Abstract

While most commentators have focused exclusively on how LLMs will transform day-to-day law practice, a substantial structural change could be afoot within the legal sector as a whole. Large increases in productivity and attendant cost savings could encourage law firms and corporate legal departments to develop large language models in-house. A ten percent increase in attorney productivity would encourage an average sized 'Big Law' firm to reduce its associate headcount by 300 to 400 lawyers. This represents cost savings of 60 to 120 million dollars - more than enough to pay for the development of a specialized LLM. Eventually, LLMs will push lawyers into highly specialized and nuanced roles. After fully mature LLMs arrive, the lawyer will continue to play a central role in legal practice, but only in non-routine legal tasks. These tasks will primarily involve value judgments, such as the development of precedent or its reversal, or the allocation of property and other scarce resources. This new mix of lawyer-machine labor, where machines primarily carry out routine legal tasks, and lawyers handle the non-routine, will give rise to a growing demand for lawyers who can exercise good judgment and empathize with the winners and losers of social change. Overall, the Article suggests a possible future where there are fewer lawyers and greater consolidation of the legal sector.
