AI + Client Confidentiality: A Practical Checklist for Law Firms

Practical confidentiality checklist

Executive Summary

Most lawyers don’t need “more AI”. They need a safe way to use it in real matters without losing control over confidentiality, sources, and accountability.

This checklist is meant to be practical: what to avoid, what to redact, and what to keep inside a controlled workflow, so the lawyer stays in the driver’s seat.

Key Takeaways

  • Start with a “data diet”: keep identifiers and sensitive facts out unless you truly need them.
  • Separate thinking from filing: use AI for structure, alternatives, and checks — but verify before you send.
  • Prefer workflows over free chat: controlled steps, inputs, and checkpoints reduce risk.

1) First decide: what are you asking AI to do?

Before you paste anything, define the output: a short memo, a legal opinion outline, a risk list, a contract clause comparison, or a negotiation plan. “Help me with this case” is too broad.

Clarity makes you safer — because you can limit the inputs to what’s needed.

2) Categorize your inputs (and cut aggressively)

Think in three buckets:

If you can solve the task with bucket #1 or #2, don’t use bucket #3.

Practical rule of thumb

If you would not forward the text to a trusted colleague over email without a second thought, don’t paste it into an AI tool as-is. Redact or restructure first.

3) Redact smart: keep what matters for the legal analysis

Bad redaction removes the legal signal. Good redaction removes the identifiers.

Redact these by default

  • Names of people and companies (replace with “Client”, “Supplier”, “Employee”).
  • Case numbers, deal codes, invoice numbers.
  • Addresses, phone numbers, personal IDs.
  • Exact dates when not essential (use relative timelines: “T0”, “T+30 days”).

Keep these when needed for accuracy

  • Jurisdiction, forum, and governing law.
  • The legally relevant sequence of events.
  • The key contractual clause text (only the clause, not the full contract).

4) Use AI for “structure + alternatives” — not as the final authority

AI is useful for:

AI is risky when used as a source of truth. Your safety comes from verification, citations, and checkpoints.

5) Prefer a controlled workflow (Agentic Tasks) over ad-hoc copy/paste

A workflow approach is safer because it encourages a consistent sequence:

That’s the direction Wisanna is built around: lawyer-controlled workflows from intake to deliverable, with explicit checkpoints.

6) A simple internal policy (you can adopt today)

One-page AI confidentiality policy

  • Default to anonymized facts; never paste identities unless necessary.
  • Never paste privileged client communications into generic tools.
  • Use AI for structure and options; verify before sending to anyone.
  • Keep a short “what we used AI for” note in the file (for internal accountability).
