How to Set Up Claude Safely in a Small Law Firm: A Step-by-Step Guide

Step 1: Use a Business Plan, Not Personal Accounts

Client work belongs on a firm-managed business plan such as Claude Team or Claude Enterprise, not on lawyers' personal accounts. Anthropic's commercial plans do not use your conversations to train its models by default, and they give the firm central administration: single sign-on, adding and removing users, and the ability to recover work when someone leaves.

Two details are worth knowing. Feedback that users submit, such as a thumbs-up or thumbs-down on a response, is treated differently from ordinary conversations, so tell your team not to submit feedback on client matters. And retention settings differ between plans; Enterprise lets an administrator set a custom retention period. Check Anthropic's current privacy documentation and commercial terms for the details of the plan you choose.

Step 2: Write the AI-Use Policy Before Anyone Starts

ABA Formal Opinion 512 (2024) applies the existing ethics rules to generative AI: lawyers must understand the tools they use, protect client information, supervise the output, and charge reasonable fees. State guidance points the same way. Florida Bar Ethics Opinion 24-1 recommends getting client consent before using third-party AI tools that involve disclosing confidential information, and the State Bar of California's practical guidance warns against entering client confidences into a tool unless you know the provider will not use them in ways such as training.

A one-page firm policy should answer:

• Which tools are approved, and on which accounts.
• What client information may and may not be entered.
• How clients are told, and when their consent is obtained (often in the engagement letter).
• Who checks AI output, and how citations are verified before anything is filed or sent.
• How AI-assisted work is billed. Opinion 512 says hourly billing must reflect time actually spent, not time saved.

Step 3: Build a Project for Each Practice Group

Projects give Claude persistent context. Create one for each practice group or matter type, and load it with the documents that define how your firm works: your precedents and templates, your house style guide, your checklists, and standing instructions such as your citation format and the jurisdictions you practise in. Every lawyer who works in that project starts from the same firm knowledge instead of a blank prompt.

Step 4: Turn Repeatable Work Into Skills

Skills are written instructions Claude applies whenever a task calls for them, such as how your firm summarises a deposition, drafts a demand letter or formats a research memo. Claude for Legal includes practice-area plugins that bundle skills and templates, and firms can adapt them to their own style. Start with the three or four documents your firm produces most often.

Step 5: Connect Your Systems, Read-Only First

Connectors let Claude work with documents where they already live instead of being copied in. Claude for Legal announced connectors for legal systems including iManage, NetDocuments, Box, Relativity, Everlaw and Thomson Reuters CoCounsel, and practice-management vendors are adding their own. Start with read-only access, confirm the connector respects each user's existing permissions, and widen access only once the firm is comfortable.

Step 6: Check Every Output

This is the step that protects your licence. AI tools can produce confident, well-formatted citations to cases that do not exist; in Mata v. Avianca (S.D.N.Y. 2023) that led to sanctions. Make human review part of every workflow: a lawyer reads the source for every authority, checks quotations word for word, and confirms the facts against the record before anything is filed or sent to a client.

Step 7: Start Small, Train, Then Expand

Pick a handful of low-risk, high-volume workflows to start with:

• Summaries of deposition transcripts and medical records.
• First drafts of routine letters and discovery requests from your templates.
• Organising intake information into your matter checklist.
• Research starting points that a lawyer then verifies.
