How to Write a One-Page AI Usage Policy for Your Law Firm
Your team is already using AI. Staff may be drafting emails with a chatbot, summarising long documents or checking wording before a client letter goes out. Most of this happens without a written rule, and that is the risk.
A short AI usage policy sets clear limits. It protects client confidentiality, gives staff a safe way to use the tools that help, and shows clients and regulators that the firm is in control. For a firm with 5 to 50 staff, one page is enough. If you want help with the wider picture, see our AI risk and governance service.
Why a small firm needs a policy now
Client information is the main concern. Pasting a client’s name, case details or financial information into a public AI tool can send that data to a third party you have not vetted. Once it has left the firm, you cannot easily recall it.
Accuracy is the second concern. AI tools can produce confident but wrong answers, including invented case references. A lawyer remains responsible for every piece of work that leaves the firm, whether or not AI helped produce it.
The Solicitors Regulation Authority (SRA) expects firms to protect client confidentiality and to supervise work properly. Check the current SRA guidance on AI before you finalise your policy, as the position may change. Our legal sector page explains how we support law firms.
The six sections of a one-page policy
Keep each section to two or three sentences. Staff should be able to read the whole document in five minutes.
1. Purpose and scope. State why the policy exists and who it covers. Include partners, employees, trainees and contractors.
2. Approved tools. List the AI tools staff may use, such as a named enterprise product with a data processing agreement. Say that any other tool needs written approval from a named person, such as the practice manager or the compliance lead.
3. What must never go into an AI tool. Name the data types that are off limits. For most firms this includes client names, case details, financial information, privileged material and anything covered by UK GDPR, unless the approved tool is set up to handle it.
4. Human review. Every AI output must be checked by a qualified person before it is used. This covers legal research, drafts, summaries and client communications. The reviewer owns the result.
5. Disclosure and records. Explain when staff must tell a supervisor that AI was used, and where to note it on a file if your firm chooses to do so.
6. Training, breaches and review. Require staff to complete a short induction. Tell them how to report a mistake or a data incident quickly. Set a review date, such as every 12 months.
Three rules that do most of the work
If your firm adopts only three rules, make them these:
- No client-identifiable data in unapproved tools. Anonymise a case before any AI use, or do not use AI for it.
- A qualified person checks every output. AI drafts are starting points, never final work.
- Report mistakes early. A wrong citation caught internally is a training point. One that reaches a client is a serious problem.
Common mistakes to avoid
- A policy nobody reads. Put it in the staff handbook and walk through it in a team meeting.
- Banning AI outright. Staff will use it anyway, in secret. A supported, approved route is safer.
- Writing it once and forgetting it. Tools change quickly. Review the policy at least once a year.
Next steps for your firm
- Ask your IT provider or software supplier whether the tools you use are covered by a data processing agreement. An AI readiness review can help you spot gaps.
- Agree the approved tool list with a partner.
- Draft the six sections above in plain English.
- Brief the team and collect signed acknowledgements.
A policy is not a legal guarantee, and it does not replace advice from your regulator or a lawyer. It does give your team a clear, written standard to work to.
