Start with the line, not the hype
You will have heard that AI is about to change legal practice. You will also have noticed that the people saying so are rarely the ones who would have to explain a defective filing to a judge, a client or a regulator.
So this course takes a narrower and more useful view. There is a line running through your working day. On one side are tasks where AI can save real time and the worst case is a clumsy sentence you fix before anyone sees it. On the other side are tasks where the worst case is a wrong statement of law, a misdescribed fact or an authority that does not exist, sitting in a document with your name on it. Everything in the next six lessons is about knowing which side of that line you are on.
This course is general education about using AI tools. It is not legal advice, and it does not state the law, the professional conduct rules or the court rules of any jurisdiction. Those differ between countries, courts and regulators, and they change. Your obligations are set by your own regulator, bar or law society, the courts you appear in, and your firm or organisation. Check their current guidance and follow it. Where this course and those rules differ, the rules win.
The fact that draws the line is simple. A chat AI tool produces text that reads like a good answer. It does not look anything up unless it has been given a search tool and actually used it, and even then it does not reason about your client's position the way you do. It writes what plausibly comes next. Plausible and correct are separate properties, and in legal work the gap between them is where the damage happens.
In plain English
- Large language model:
- The technology behind chat AI tools. It predicts likely text one piece at a time. It is not a legal database and does not know which answers are true.
- Prompt:
- What you type in. Clear context, a defined task and explicit limits make the reply more useful and easier to check.
- Hallucination:
- A fluent, confident, invented answer. In legal work the classic example is a case or quotation that does not exist.
- Context window:
- How much text the tool can hold at once. Paste in a very long bundle and earlier material may quietly drop out of view.
- Approved tool:
- An AI tool your firm or organisation has assessed and authorised for particular kinds of work, on particular terms.
Where it genuinely helps
These are language and organisation tasks. That is what the technology is actually good at.
Summarising for a first read. A long agreement, a witness statement, a set of meeting notes, correspondence running to hundreds of pages. A summary helps you find your way in and decide where to read closely. It does not replace reading the parts you rely on. Lesson two covers this in detail.
First drafts of routine documents. Covering letters, engagement letter wording you will adapt from your own precedent, a standard chaser, a file note structure. You are the author. The tool gives you something to edit rather than a blank page.
Organising facts and chronologies. Give it your own notes or a set of documents you are entitled to process, and ask for a dated chronology with a source reference against every entry. That last part matters, because it lets you check each line.
Plain-English explanations for clients. You already know what a clause does or what the next procedural step involves. Turning that into something a non-lawyer can follow without feeling talked down to is a separate skill, and AI is often good at the first draft of it.
Checklists. Closing checklists, document review checklists, intake questions, a list of things to confirm before a hearing. It is good at structure. You decide what belongs on the list.
Notice the pattern. On every task above, either you already know the substance and want help expressing or arranging it, or you will read every word of the output against a source before relying on it.
Where it does not
Legal conclusions. Whether a clause is enforceable, whether a claim has merit, whether a limitation period has run. The tool will answer these questions fluently. It has no reliable basis for doing so, and it will not flag which parts of its answer are guesswork.
Advice. Advice applies the law to a client's specific facts and circumstances, and someone has to be answerable for it. That is you, not software.
Authorities. Cases, statutes, rules and quotations must come from primary sources you have read yourself. Lesson three explains why this is the risk that ends careers.
Anything you have not verified. If a statement of fact or law appears in your work, you should be able to say where it came from and that you checked it.
Checkpoint
AI can help with summarising, routine drafting, chronologies, plain-English explanations and checklists, but legal conclusions, advice, authorities and anything unverified stay with you.
A prompt that stays on the right side
The way you frame a request decides which side of the line you land on. Compare these.
โ Weak prompt
Prompt
My client signed a supply agreement with a two-year minimum term. Can they terminate early without paying damages?
Output
Yes. Your client can terminate early if the supplier has committed a material breach. They would not be liable for damages in that case.
A confident legal conclusion about a contract it has not seen, under a governing law it does not know, on facts it has not been given. It answered because it always answers.
โ Good prompt
Prompt
I am reviewing a supply agreement for early termination rights. Do not tell me whether the client can terminate and do not give legal conclusions. From the text below, list every clause that deals with term, termination, notice, breach or remedies. Quote each one exactly with its clause number. Then list any definitions those clauses depend on. [agreement text, in a tool approved for it]
Output
A list of the relevant clauses quoted verbatim with clause numbers, followed by the defined terms they rely on.
This is retrieval from a document you supplied, which it does reasonably well and which you can check line by line. The legal analysis stays with you.
From the material below, build a chronology in date order.
For each entry give: the date, what happened in one sentence,
and the exact document and page or paragraph it comes from.
If a date is uncertain or inferred, mark it UNCERTAIN and say why.
Do not add any event that is not in the material.
Do not draw conclusions about liability or legal consequences.
[paste material you are permitted to use in this tool]
That instruction not to add events is worth including every time. Models sometimes fill gaps with things that sound likely. A source reference against every line is how you catch it.
One more habit before the next lesson: before you paste anything at all, ask whether this tool is one your firm has approved for this kind of material. Lesson four covers confidentiality properly. Until then, the safe default is that client material does not go into a tool you have not been told you may use.
