Should a law firm website have a chatbot?

A law firm website chatbot is worth having if it solves a real gap, usually enquiries arriving when nobody can reply, and if it is limited to collecting details and booking a callback rather than answering legal questions. The SRA has said firms remain responsible for errors in advice given by a third-party chatbot, so accuracy, disclosure and data protection need settling first.

This post weighs the case for and against from an operator's point of view: what problem a chatbot solves, what it costs in risk, and what else might solve the same problem better. It is part of our guide to how law firms get clients.

What does a chatbot on a law firm website actually do?

"Chatbot" covers several quite different things, and the differences matter more than the label:

• Scripted chat. A decision tree: the visitor picks from buttons, the bot collects name, number and matter type. Predictable and limited.
• Live chat with humans. A person, in-house or outsourced, typing replies. Only as good as the hours it is staffed.
• Generative AI chat. A language model that writes its own replies. Flexible, and the most likely to say something the firm would not.
• Hybrid. An AI or scripted front end that hands over to a person, or books a call.

Before deciding whether to have one, decide which kind you would be buying, and for which job.

What are the benefits of a chatbot for a law firm?

The SRA's Risk Outlook report on AI in the legal market (November 2023) describes the potential clearly: chatbots can respond quickly to enquiries from potential clients and potentially offer a 24/7 service for answering common questions, gathering and sorting information and triaging cases for seriousness and urgency.

In practice, the benefits a firm can reasonably expect are:

• Capture outside office hours. A visitor at 10pm leaves details instead of leaving the site.
• Consistent first questions. Every enquiry gets the same qualifying questions.
• Routing. Matter type and urgency identified before a person sees it.
• Relief for reception, if a large share of contacts are simple and repetitive.

What are the risks of a chatbot on a law firm website?

The same SRA report sets out risks that apply directly:

• Accuracy. It warns that AI language models can "hallucinate", producing plausible but incorrect results.
• Responsibility. It says that if you use a third-party chatbot to provide initial legal advice, you remain responsible for any errors in that advice.
• Confidentiality. Client information passing to a provider, and how it is stored and used.
• Transparency. The report says firms should tell clients when they will be using AI with their case and how it will operate.

Add the commercial risks an operator would flag:

• Frustration. A visitor who wanted to talk to a person and got a bot may leave annoyed.
• False reassurance. A bot that says "someone will be in touch shortly" at 10pm on a Friday is making a promise the firm may not keep.
• Something that reads like advice. Even a scripted bot can say things like "you are likely to be entitled to..." if its copy is written carelessly. Paragraph 8.8 of the SRA Code of Conduct requires publicity about the firm's services to be accurate and not misleading.
• Sensitive data. Family, immigration, crime and employment enquiries often include health, criminal or other special category information. That brings UK GDPR obligations your data protection lead will want to review.

Does a chatbot help law firm conversion?

It can, but only for the share of visitors who would rather type than talk, and only if the firm follows up. A chatbot that collects details at 10pm and hands them to an inbox nobody reads until 11am the next day has moved the leak rather than fixed it.

The test is the same one we apply to every channel in how to generate leads for a law firm: time to first human contact, and conversion to instruction. Measure both before and after.

A decision test: does your firm need a chatbot?

Answer these five questions honestly.

• 1. What share of your website enquiries arrive outside office hours? If you do not know, find out first. If it is small, a chatbot solves little.
• 2. Do those visitors want to type, or to talk? Look at whether your out-of-hours visitors fill in forms or try to call. Some enquirers would much rather speak to someone.
• 3. Who follows up, and how fast? If the answer is "the next working day", the gain is limited.
• 4. Can you keep it from answering legal questions? If the tool cannot be reliably restricted to collecting details and booking a call, the SRA's point about responsibility for errors applies.
• 5. Can you explain it to a client? What it is, that it is not a person if it is not, what happens to their data, and who reads the conversation.

If you answer the first three with "a lot", "type" and "within the hour", a narrowly scoped chatbot may help. If the answers are "not sure", "talk" and "tomorrow", fix the phone and the follow-up first.

A worked example: chat or phone?

Invented numbers, for illustration. A hypothetical firm's website produces 60 enquiries a month. Its call tracking shows 45 are phone calls, and 15 are forms. Of the calls, 14 arrive after hours and go to voicemail. Of the forms, 6 arrive after hours.

A chatbot might capture some visitors who currently leave without doing anything, which the firm cannot measure yet. But the known leak is the 14 callers who reached voicemail, more than twice the out-of-hours form volume. On these numbers, the first fix is answering the phone after hours; a chatbot is a second, smaller project. A firm whose numbers run the other way, with most enquiries coming through forms, might reasonably do it in the reverse order.

What should a law firm ask a chatbot vendor?

• Is it scripted, generative, human, or a mix? What exactly writes the replies?
• Can it be restricted so it never answers legal questions, and how is that tested?
• Does it tell visitors clearly that it is automated?
• Where is conversation data stored, for how long, and is it used to train anything?
• What special category data might it collect, and how is that protected?
• How is an enquiry handed to a person, and how quickly?
• What happens with an urgent or safeguarding situation, such as a threat to someone's safety?
• Can the firm export and delete conversations?
• What does it cost, including per-conversation charges?

Is a chatbot suitable for every practice area?

Not equally. In practice areas where enquirers are distressed, such as family or crime, a person or a spoken conversation may matter more, and the safety questions are sharper. We cover the family case in marketing a family law firm. In high-volume, well-defined work such as residential conveyancing quotes, a structured chat or form can work well, alongside the price information the SRA Transparency Rules already require on the website.

What are the alternatives to a website chatbot?

• A better form, with fewer fields and a clear promise about when a person will reply, backed by someone who keeps it.
• Covering the phone at lunchtime and after hours.
• A callback booking link, so a visitor can pick a time.
• Clearer service pages, so fewer visitors need to ask the basic questions at all. See why your law firm website gets visits but not enquiries.

How should a firm introduce a chatbot, if it decides to?

If the decision test points towards a chatbot, a cautious rollout reduces the risks described above:

• Start narrow. Collect name, contact details, matter type, urgency and a preferred callback time. Nothing else.
• Write every fixed message yourself, and have a fee-earner read them for anything that sounds like advice or a promise.
• Say what it is on the first line. An automated assistant that collects details for the firm, not a lawyer.
• Set the expectation honestly. "A member of our team will contact you on [next working day] morning" is better than "shortly" if that is the truth.
• Test the edge cases. What happens if someone types that they are in danger, that a hearing is tomorrow, or that they want to complain?
• Review a sample of conversations weekly for the first few months, and keep a record of what you changed and why.
• Measure. Time to first human contact and conversion for chatbot enquiries, compared with forms and calls.

After three months, the numbers will tell you whether it earned its place. If it did not, removing it is a perfectly good outcome of a well-run test.

Where WasilX fits

We do not sell a website chatbot. Cam, our AI Engagement Coordinator, works on the phone: it takes calls on the firm's line at any hour, says it is AI, asks the firm's own qualifying questions, books the call back and sends the firm a summary. Cam does not give legal advice. Whether an AI should answer a firm's calls at all is a fair question, and we set out the regulatory position in can a UK law firm let AI answer client calls?. If after-hours calls are your larger gap, we would be happy to talk.

Frequently asked questions

Should a law firm website have a chatbot? Only if it fills a real gap, usually enquiries arriving when nobody can reply, and if it is limited to collecting details and booking a callback. Measure your out-of-hours enquiries and follow-up times first.

Can a law firm chatbot give legal advice? The SRA's Risk Outlook report on AI says that if a firm uses a third-party chatbot to provide initial legal advice, the firm remains responsible for any errors. Most firms limit chatbots to collecting details for that reason.

Do law firms have to tell clients they are using AI? The SRA's Risk Outlook report says firms should tell clients when they will be using AI with their case and how it will operate. Your COLP can advise on how that applies to your firm.

Is live chat better than a chatbot for a law firm? Live chat with people avoids the accuracy risks of generative AI but only helps during the hours it is staffed. The right choice depends on when your enquiries arrive and who can follow them up.

What data protection issues does a law firm chatbot raise? Enquiries can include special category data such as health or criminal information, and conversations may be stored by a provider. Your data protection lead should review where data goes, how long it is kept and whether it is used for training.
