Claude for Lawyers: 20 Free Prompts and Safe-Use Rules

Lawyers who use Claude well get a faster first draft and keep full control of the work. The key is knowing what to paste, what to leave out, and what to check.

A lot of lawyers are stuck in the same place with Claude. They have heard it can save hours, they have also heard the stories about invented case citations, and they do not know where the safe middle is. So they either avoid it completely or paste in a client file and hope for the best. Neither is a good plan.

This guide is for practicing lawyers, solo practitioners, small firm owners, and paralegals who want to use Claude for lawyers' day-to-day work without putting their license or their clients at risk. I will show you what Claude is genuinely good at, five safe-use rules, and eight copy-paste prompts you can try today. The other twelve prompts are in the free pack at the end.

If you are brand new to Claude, spend five minutes on how to start using Claude AI as a complete beginner first. If you work inside a company legal department, my pack for in-house legal counsel covers that side in more depth.

What Claude Can Do for a Lawyer (and What It Cannot)

Claude is an AI assistant made by Anthropic. You type a request in plain English, and it reads, summarizes, drafts, compares, and explains. For legal work, that makes it a very fast first-draft partner.

Here is where it helps most:

• Summarizing long documents. Paste in a deposition excerpt, a statute, or a 40-page agreement and ask for the key points in plain language.
• Drafting first versions. Client letters, memos, demand letters, and standard clauses all start faster when you are editing instead of staring at a blank page.
• Reviewing contracts for issues. It can flag unusual terms, missing protections, and inconsistencies for you to check.
• Translating legalese. It can turn dense language into something a client will actually read.

Here is what it cannot do:

• It does not know your jurisdiction's current law unless you give it the text.
• It can state something wrong with total confidence, including citations to cases that do not exist.
• It does not replace your judgment. It produces a draft, and you are the lawyer.

That last point matters more than any prompt below.

5 Safe-Use Rules Before You Paste Anything

The American Bar Association's first ethics guidance on generative AI, Formal Opinion 512, was issued in July 2024. It applies rules lawyers already follow: competence, confidentiality, candor to the tribunal, supervision, and reasonable fees. It is guidance, not law, and your state bar may have its own rules, so check yours. These are five habits to build around it.

1. Protect client confidentiality. Strip names, addresses, and identifying facts from anything you paste, or use a placeholder like "Client A". The ABA guidance says you should understand how a tool handles your data and may need a client's informed consent before entering client information. Boilerplate in an engagement letter is not enough. Read Anthropic's privacy policy for the plan you use, and ask your firm what it allows.
2. Verify every citation yourself. Never file or send a case name, quote, or statute that Claude gave you until you have found it in an official source or your research database. Treat its output as a lead, never as authority.
3. Give it the source material. For research tasks, paste the statute or opinion and ask Claude to work only from that text. This cuts down on made-up details.
4. Tell it your jurisdiction and role. "Act as a contracts associate in a US state firm" gets you a much better draft than a bare question.
5. Review like a supervisor. Read the output the way you would read a first-year associate's draft, and keep your own reasoning in the file. Check your state's rules on disclosing AI use to clients and courts.

If you want better results from every prompt, my Claude AI prompt formula shows the simple structure behind the prompts below: role, context, task, format, and constraints.

Claude Prompts for Lawyers

Copy any prompt into Claude and replace the text in [brackets]. Each one asks for a draft for your review and tells Claude not to invent sources.

Research and Case Summaries

1. Summarize a case or statute you pasted

You are a legal research assistant. I will paste the full text of [a court opinion or statute]. Summarize it for a [practice area] lawyer in this format: facts, issue, holding or rule, reasoning, and anything that limits how far it applies. Use only the text I provide. If something is not in the text, say "not stated". Do not add outside cases or citations.

2. Build a research plan before you open the database

I am researching [legal question] in [jurisdiction]. List the legal issues I should break this into, the search terms and synonyms to try, and the types of authority I should look for (statutes, regulations, cases, secondary sources). Do not cite any specific cases. I will find the authority myself.

Drafting

3. First draft of a client letter

Draft a client letter in plain English explaining [situation] to a client with no legal background. Cover what happened, what it means for them, their options, my recommendation of [recommendation], and the next steps with dates. Keep it under 400 words and warm but professional. Mark anything you assumed with [CHECK].

4. Turn a rough outline into a short legal memo

Turn the notes below into a memo with these headings: Question Presented, Brief Answer, Facts, Analysis, and Next Steps. Use only the facts and law in my notes. Flag gaps as [MISSING] rather than filling them in. Notes: [paste notes]

Contract Review

5. Flag risks in a contract I represent the [side] on

You are a contracts lawyer reviewing this agreement on behalf of [client side]. Read the contract below and list: (1) terms that are unusual or one-sided, (2) protections that are missing, (3) defined terms used inconsistently, and (4) deadlines and notice requirements. For each item give the clause number, a one-line risk, and a suggested fix. Contract: [paste contract]

6. Compare my draft against the other side's redline

Compare the two versions of this clause. Tell me in plain language what changed, who each change favors, and which changes I should push back on. Then draft replacement wording for the two most important ones. Original: [paste]. Their version: [paste]

Client Communication

7. Explain a legal concept without jargon

Explain [legal concept] to a small business owner who is smart but has never studied law. Use one everyday comparison, avoid Latin and legal jargon, and end with three questions they should ask me. Keep it under 250 words.

8. Prepare for a difficult client conversation

I need to tell a client that [bad news, for example the case is likely to settle for less than they hoped]. Draft talking points that are honest, kind, and clear. Include the three questions the client is most likely to ask, with suggested answers, and one sentence I can use to explain the next step.

Claude for Legal: What Anthropic Added in 2026

In May 2026, Anthropic announced Claude for Legal. It includes connectors that link Claude to legal software such as document management, e-discovery, and legal research platforms, plus 12 practice-area plugins for areas like commercial, corporate, privacy, and litigation work. Anthropic says these are available in Claude Cowork, and that Enterprise admins can switch them on in workspace settings.

For a solo lawyer or small firm, the simplest way to start is still a plain Claude chat and the prompts above. Plugins and connectors become worth the setup once you have a repeatable task, like reviewing the same type of agreement every week. If you want to keep a matter's background in one place, Claude Projects is the next thing to learn.

Features, plans, and legal integrations change quickly, so check Anthropic's page for what is current before you rely on any of them.

Common Questions About Claude for Lawyers

Can lawyers use Claude? Yes, and many do. The ABA's guidance treats AI as a tool you can use as long as you meet your existing duties of competence, confidentiality, and supervision.

Is it safe to put client information into Claude? Not by default. Remove identifying details, learn how your plan handles data, and get informed client consent where your rules require it.

Will Claude replace lawyers? No. It drafts and summarizes quickly, but it cannot take responsibility for advice, and it will sometimes be wrong. The lawyers who benefit are the ones who review its work carefully.

Can Claude do legal research? It can help you plan research and summarize text you give it. Always confirm any authority in an official source before you rely on it.

What to Do Next

Pick one task you do every week, like a client update letter or a first-pass contract read, and run the client letter prompt or the contract risk prompt on an anonymized example. Compare the draft with what you would have written, then edit your version of the prompt until it fits how you work.

The free pack below has all 20 prompts, grouped by task, plus a one-page safe-use checklist you can keep next to your keyboard. Everything in it is a first draft for your review. None of it is legal advice, and none of it replaces your professional judgment.
