AI governance for law firms, the technical way.

"Governance" is what turns scattered, invisible AI use into something a firm can see, control, and show. Here's the technology that makes that possible.

Where AI actually enters your firm's work

AI rarely arrives as a decision — it shows up task by task. It appears in a drafting tool, a research add-in, a summarizer someone tries on a deadline. The common entry points are consistent across firms:

• Drafting and correspondence — letters, memos, first drafts.
• Legal research — summaries, "find me cases," quick answers.
• Document review — first-pass sorting and categorization.
• Client intake and screening — triage and summarization of new matters.
• Summarization and analysis — long records, depositions, discovery.
• Marketing and client communications — outreach, updates, responses.

Each touchpoint raises the same technical question: is there a record of what the AI did, and can you show it? You can't govern what you haven't located, so mapping these is the first move.

What "governance" means technically

Governance often gets treated as a policy document — a memo that says "use AI responsibly." That's worth having, but on its own it's an intention, not governance. Technically, governance is the set of controls and records that let a firm see how AI is being used and demonstrate it after the fact.

It's the difference between "we tell people to be careful" and "we can show, for any AI-assisted work product, what tool and model produced it, from what inputs, and who signed off." The rest of this guide is the technical layer that makes the second sentence true.

The core controls

Governance comes down to a handful of controls. None of them is exotic; the work is applying them consistently.

• Inventory — know which tools and vendors touch client work, and what data flows to each.
• Logging — capture the prompt, the output, the model and version, the user, and the timestamp. No logs, no audit trail.
• Data handling — a defined step to protect sensitive information before it reaches a model.
• Verification and attribution — tie output back to its sources, mark AI-assisted work, and require human review before it leaves the firm.
• Version control — pin model versions and settings; models change quietly, and that can matter later.
• Access — role-based permissions and managed keys, not a shared login.
• Retention and deletion — how long AI records are kept, and how they're defensibly removed.
• Audit trail — the ability to reconstruct any AI-assisted work product on demand.

Keeping client data out of the wrong places

The highest-stakes technical control is what data reaches a third-party model. Consumer AI accounts and business accounts behave very differently: business and enterprise tiers generally let you confirm that inputs aren't used to train the model, and offer data-residency and retention controls. Consumer accounts often do neither.

Before sensitive client information goes into any tool, a defined step to remove or protect it — redaction, a data-loss-prevention rule, or a clear line about what's allowed — turns an ad-hoc risk into a managed one. This is the point where "be careful" has to become an actual control.

The audit trail — the thing you can produce

Every control above exists to produce one thing: a record you can show. If a client asks whether AI touched their matter — or a court does — the question isn't philosophical, it's technical: can you reconstruct it?

A firm with an audit trail can point to the log, the model version, the inputs, the verification step, and the person who approved the result. A firm without one is reconstructing from memory. The audit trail is the deliverable of governance; the controls are how you get there.

Where firms go wrong

The failure modes are rarely dramatic — they're quiet gaps that only surface when someone asks for the record and it isn't there:

• Relying on people to simply remember what they did.
• Using consumer accounts for client work.
• Treating AI output as final because it reads well.
• Keeping no record of the verification that did happen.
• Having a policy that no system actually enforces.

Where to start

You don't build all of this at once. Most firms move along a path — from AI in use with no record, through ad-hoc habits, to structured practices, to documented controls, to a setup that's genuinely audit-ready. The fastest way to see where you stand is to look at the specific controls and find the gaps.
