Mid-Size Law Firm AI Adoption: A Composite Case Study

How a mid-size litigation firm typically scopes an AI pilot, measures it and rolls it out across practice groups.

Composite scenario. This is an illustrative scenario built from common adoption patterns, not a profile of a real organisation. It contains no real names, quotes or measured results. Use it as a planning template and replace every assumption with your own data.

The starting point

A litigation-focused firm of a few dozen lawyers spends much of its associate time on document review and first-draft research memos. Clients are pushing back on review bills, and partners are sceptical of AI after seeing news of fabricated citations.

Pilot design

Getting partners on board

Typical concerns are accuracy, defensibility and the effect on billable hours. A side-by-side comparison on a closed matter answers the first two better than any vendor demo. The billing question needs a deliberate decision: fixed fees for review phases, or passing savings to clients, both of which ABA Formal Opinion 512 touches on.

Rolling out

  1. Write a short AI-use protocol for review (who designs prompts, who validates, how decisions are recorded).
  2. Train a small group of "review leads" before opening it to all associates.
  3. Add AI-assisted research separately, with a strict citation-checking rule.
  4. Tell clients how AI is used on their matters, and update engagement letters.
