AI for solicitors: a practical guide for England & Wales

AI can take real work off your desk — drafting, review, client letters. The trick is using it so it saves time without ever putting your name to something you haven't checked. Here's how a practising solicitor actually does it.

In short

Generative AI has moved from novelty to fixture. The Solicitors Regulation Authority's own research found that AI use is rising rapidly across the profession, with even small firms increasingly exploring generative tools. For a solo practitioner or a small commercial team, the appeal is obvious: the work that eats your evenings — first drafts, contract reviews, client updates — is exactly the work AI can accelerate.

But acceleration isn't the point. Getting it right, every time, in a way you can stand behind professionally, is the point. This guide is about the second thing.

What AI is genuinely good at in legal practice

AI is not a replacement for your judgement, and the tasks where it earns its place reflect that. It is strongest where there is a structure to follow and a source to work from:

What these have in common: a real document goes in, and the AI works from it rather than from its own "knowledge." That distinction is the whole game. AI contract review done well means giving the model the actual contract; done badly, it means asking the model what a contract "usually" says.

Where it goes wrong — and why that matters for you

The risk that should concern every solicitor is fabrication. Large language models produce fluent, confident text whether or not the underlying facts are real. Ask for authority and a model may invent a case, a citation, or a statutory provision that does not exist — and present it as indistinguishable from the genuine article.

This is not hypothetical. In Ayinde v Haringey, fictitious authorities generated by AI were put before the High Court, and the Divisional Court set out in unambiguous terms what the profession's duty now is. We cover that case in depth in Ayinde v Haringey explained.

Your professional obligations don't change

The Law Society's guidance is clear that a solicitor's duties — in particular to the court and to the client — apply to work carried out with AI exactly as they apply to anything else, whether the AI was used by you or by someone you supervise. Even where outputs are AI-derived, that does not absolve you of responsibility or liability if the result is wrong.

In practice that means the relevant parts of the SRA Code — competence, supervision, confidentiality, acting in the client's best interests — are the frame for everything you do with these tools. The work remains yours.

How to actually start

You don't need to be technical, and you don't need to overhaul your practice. The sensible path:

  1. Pick one repeatable task you do often — say, reviewing a particular kind of agreement, or drafting a particular client letter.
  2. Work from real documents — your precedent, the counterparty's draft, the instructions transcript — never from the model's general knowledge.
  3. Verify everything before it leaves your desk. Treat AI output the way you'd treat a trainee's first draft: useful, but checked.
  4. Build a consistent standard so every output holds to your house style and positions, not the model's defaults.

That last point — consistency and a built-in verification standard — is exactly what The Lawyer's Prompt and its installable Claude skills are designed to give you. The book teaches the discipline; the skills apply it automatically.

If you want the deeper dives: Claude for lawyers, how to verify AI output, and practice-specific prompt guides for commercial, employment and property work.

Use AI properly. Then get on with the work.

The book to learn it, the skills to do it — drafting and review in your own house style, with nothing going out you haven't checked.
