What ChatGPT genuinely does well for legal work, where it fails in ways that can hurt you, the confidentiality rules that must come first — and 25 ready-to-use prompts to put it to work today.
Learn how law firms use ChatGPT for legal research, contract analysis, and document drafting. Want AI grounded in your actual matters, not general prompts? See SpineLegal's Legal AI.
Whether or not your firm has an AI policy, your lawyers are almost certainly already using ChatGPT — to untangle a clause, draft a first-pass email, or summarise something long. That informal adoption is exactly why a practical, honest guide matters: the productivity gains are real, and so are the risks.
This guide covers what ChatGPT does well for legal workflows, where it fails, how to use it without breaching your duties — and gives you a working prompt library to start from.
Yes — with discipline. ChatGPT is a public, general-purpose tool that was not built for legal practice, and three rules protect you, your firm and your clients:
2. Verify everything — especially citations. ChatGPT can produce confident, plausible, wrong answers, including invented case law. Treat every output as a first draft from a bright but unsupervised trainee: useful, never final. Nothing reaches a client, a court or a regulator without qualified human review.
3. Have a firm AI policy — and follow it. If your firm doesn't have one yet, the two rules above are a reasonable start, and worth formalising before AI use spreads informally.
Client letters, plain-English clause rewrites, letters before action structures, witness statement outlines — with your review as the final step.
Long correspondence chains, chronologies from documents, obligations extracted from contracts into tables, version comparisons.
Translating legal concepts into plain English, structuring difficult-news emails, drafting update templates and practice-area FAQs.
Arguing both sides of an anonymised dispute, attacking your own position, building checklists, negotiation preparation.
It can invent authorities that look entirely real. Frame research prompts as questions-to-verify, never as facts to rely on.
ChatGPT has never seen your files. Every use starts with you assembling anonymised context by hand — pasting, redacting, re-explaining.
From our 25-prompt library — replace the [brackets] with anonymised detail and paste straight in.
From this contract, extract every obligation into a table: who owes it, to whom, what triggers it, deadline, and consequence of breach. Then list the five obligations most likely to cause a dispute and why. [paste anonymised contract]
Tip: the "most likely to cause a dispute" ranking is a client conversation in itself.
Act as opposing counsel. Here is my client's position: [anonymised summary]. Write the skeleton of the attack you would run against it — weakest points first — and what evidence you would demand.
Tip: do this before the other side does it for you.
Explain [legal concept, e.g. "an unless order"] to a client with no legal background, in under 150 words, using one everyday analogy. Then add one sentence on why it matters in their situation: [anonymised context]
Tip: cap the word count or you'll get an essay.
Ready-to-use prompts for ChatGPT, Claude, Copilot and Grok across five categories: drafting & documents, summarising & analysis, client communication, legal thinking, and practice operations. Each with placeholders and a tip from real practice use — plus the safety rules that keep them defensible.

Every prompt on this page shares one limitation: the AI answering it has never seen your files. It doesn't know your client, your correspondence, your deadlines, or the stage a matter has reached — which is why every use begins with you assembling anonymised context by hand.
SpineLegal takes the other route. It's an AI-native practice management platform where every matter carries its own assistant — the Matter Assistant — grounded in that matter's file, inheriting each user's access permissions, with client data never used to train AI models and nothing sent or filed without a fee earner's confirmation. Use ChatGPT for the generic work; use AI grounded in your matters for the legal work.
Matter-aware by design — drafts, summaries and answers come from the matter's own documents and history, no pasting required.
Confidential by architecture — documents stay in your firm's own Microsoft environment; AI operates inside it, and every output is reviewed before release.
Workflows with AI steps — document generation, bundle preparation and client updates built into your firm's own workflows, each under human review.
"We're able to quickly search for trade mark application and registration numbers under our care and instantly access case information, staff notes, and upcoming deadlines. The daily deadline email notifications to the team are reliable and ensure everyone is aware of their priorities."
Trade Mark Wizards — SpineLegal client
Yes — many already do, for drafting assistance, summarising and internal work. The non-negotiable rule: client-identifiable information never goes into a public AI tool, and every output is verified by a qualified lawyer before anyone relies on it.
No. Public AI tools may retain, log or train on what you type, so entering client-identifiable data may breach your confidentiality obligations. Anonymise everything — or use a platform where the AI operates inside your firm's own secure environment and your data is never used to train models.
With caution. It explains concepts and structures research questions well, but it can invent plausible-looking citations. Treat any authority it names as unverified until checked against a primary source.
Prompts that give the model a role, a specific task, an answer structure, and anonymised context. Our free Legal AI Prompt Library contains 25 of them across drafting, summarising, client communication, legal thinking and practice operations.
ChatGPT knows nothing about your matters — you supply context by hand every time. Legal AI built into practice management, like SpineLegal's Matter Assistant, is grounded in each matter's file, inherits user permissions, and keeps client data inside the firm's environment.
Book a 15-minute walkthrough and we'll show you the Matter Assistant working on workflows that look like yours — with a free 14-day trial included.
