AI Prompts for Solo and Small-Firm Lawyers That Protect Confidentiality

AI tools can save a lawyer or a small team hours each week on drafting, outlining, and brainstorming. They can also create real risk if you paste in client information or trust the output without checking it. The goal is to use AI where the stakes are low and your review is easy.

Set your ground rules first

Before you write a single prompt, decide what is off limits, and if you have staff, write it down and share it with everyone:

• No client names, facts, or documents in tools you have not vetted
• No confidential or privileged information in consumer-grade tools
• No filing, sending, or publishing anything you have not read line by line
• No reliance on AI for legal citations without verifying each one yourself

Check your state bar’s guidance on AI and your tool’s data and retention policies. Rules vary and are changing, so revisit them periodically.

Prompt pattern: role, task, audience, constraints

Good prompts are specific. Use this structure:

1. Role: “You are an experienced marketing writer for a small law firm.”
2. Task: “Draft a 300-word blog post explaining how probate works.”
3. Audience: “Readers are adults with no legal background, in [state].”
4. Constraints: “Plain language, no guarantees, no legal advice, include a general-information disclaimer.”

The more precisely you describe the output, the less time you spend editing.

Safe, useful tasks to start with

• Brainstorm ten blog or video topics for your practice area
• Turn your own bullet notes into a first draft of an article
• Rewrite a dense paragraph in plain language
• Create a checklist for your own office procedures
• Draft a polite follow-up email template with placeholders instead of real names

Notice that none of these require client data. Use placeholders such as [CLIENT] and [DATE] whenever you build templates.

Build a prompt library

When a prompt works, save it in a shared document with a title, the prompt text, and notes on what to check. Over time you will have a small toolkit for repeated tasks, and an assistant can use it without reinventing the wheel.

Always review and edit

AI output can be confident and wrong. Check facts, jurisdiction-specific details, and tone. Make sure the final piece sounds like you and meets advertising rules, including any required disclaimers. You remain responsible for everything you publish.

Consider disclosure and supervision

If a staff member or contractor uses AI on your behalf, give them written rules. Depending on your jurisdiction and the task, you may also have duties around competence, supervision, and communicating with clients about AI use.

Write your four ground rules on one page today. Then pick one low-risk task from the list above, create a prompt using the role-task-audience-constraints pattern, and test it this week. Save it if it works.
