What an AI answering service can and cannot do for a law firm
An AI answering service answers your firm's calls, identifies what the caller needs, captures the facts of a new enquiry, books the callback or first appointment, and routes anything urgent to a named person. It does this on the first ring, at any hour, and it does not queue when several people ring at once.
What it must not do is give legal advice, quote fees, accept instructions or clear a conflict. Those are decisions that belong to a qualified person at your firm, and a provider who blurs that line is selling you a risk rather than a service.
The rest of this page is about how to tell the difference, and what to test before you buy from anyone. Prices and product details were checked on 4 September 2026.
Why the first firm to answer usually gets the instruction
Someone looking for a solicitor is rarely loyal at the point of first contact. They have a problem that has just become urgent, a list of three or four firms, and they work down it until a person picks up. The firm that answers is the firm that gets the conversation, and the conversation is where the instruction is won.
This is why an unanswered phone costs a law firm more than it costs most businesses. A missed call in a shop is a missed sale. A missed call at a law firm can be a probate matter, a conveyancing transaction or an employment claim, and the value of one of those is not measured in tens of pounds.
The calls that go unanswered are also predictable. They arrive while your fee earners are in court, in a meeting, or with a client. They arrive at 6.10pm after the switchboard has closed. They arrive on a Saturday when someone has just been arrested, served with a notice, or had an offer accepted on a house.
What the AI actually does on a new enquiry call
The useful question is not whether the software sounds human. It is what state your firm is in when the call ends.
A good AI answering service will answer in your firm's name, establish which department or matter type the caller needs, capture the facts a fee earner needs before ringing back, take contact details and confirm them, offer and book an appointment or callback slot, and flag anything time-critical straight to a person rather than into a queue.
What you should get afterwards is a structured record, not a message. The difference matters: a name and a number means someone at your firm still has to do the intake call. A completed intake means the fee earner rings back already knowing what the matter is.
The hard line: what it must never do
This is the part to be strict about, and the part where providers vary most.
No legal advice. Not a view on merits, not "you probably have a claim", not an opinion on time limits. Anything that sounds like advice creates a duty the firm did not intend to assume.
No fee quotes. A figure given on an answering call becomes the figure the client believes they were promised. Fee questions should be captured and routed, never answered.
No accepting instructions. A retainer starts when the firm says it starts, in writing, after the client care process.
No conflict clearance. The service can capture the names needed for a check. It must never tell a caller the firm is able to act.
Ask any provider to show you, in writing, how each of these four is enforced. "The AI is instructed not to" is a weaker answer than a hard rule that refuses the topic and hands off.
Conflict screening: the question most firms ask first
An answering service cannot run your conflict check, and should not try. What it can do is collect the information the check needs at the moment the caller is on the phone and willing to give it: their full name, the other side's name, the matter type and a short description of what has happened.
That gets the check started hours earlier than it otherwise would, because the alternative is a voicemail with a first name and a number, and a fee earner playing telephone tag for two days before anyone can run a search.
The rule to insist on is that nothing the caller is told implies the firm can act. Capturing details is intake. Saying "we can help with that" is not.
Confidentiality, GDPR and where the recordings sit
Any call to a law firm may carry privileged or confidential information from the first sentence, so the data questions are not an afterthought here.
Get written answers to five things before you sign with any provider:
Where is call audio processed and stored, and under which jurisdiction? For a UK firm this is usually the first question a compliance officer asks.
How long are recordings and transcripts retained, and can you set that period yourself?
Who at the provider can access them, and is that access logged?
Is there a data processing agreement, and does it name the sub-processors? Voco's is published at voco data processing agreement.
What happens to the data when you leave, and how quickly is it deleted?
A provider who cannot answer those in writing is not ready for regulated work, whatever the demo sounds like.
How it differs by practice area
The service is the same underneath. What changes is what counts as urgent and what a fee earner needs captured before the call back.
Practice area | What the caller usually wants | What to capture on the call |
|---|---|---|
Conveyancing | A quote, or a chase on an existing matter | Address, tenure, stage reached, chain position, whether an offer is accepted. See answering service for conveyancers |
Family | To speak to someone today, often in distress | Safe contact preferences before anything else, matter type, whether children or safety are involved. See answering service for family law |
Personal injury | To know whether they have a claim | Date of the accident, what happened, whether they have seen a doctor. Never an opinion on merits |
Private client | Wills, probate, powers of attorney | Whether someone has died, whether there is a will, relationship to the deceased, and a gentle tone throughout |
Employment | Usually a deadline they may not know about | Dates, employment status, what has happened and when. Flag anything date-sensitive to a person immediately |
The safe contact point for family matters is the one most providers miss. Asking whether it is safe to call back on the number the caller is using, before taking anything else, is a small thing that matters enormously.
Five calls to make before you buy from anyone
This is the most useful thing in this article, and it works on any provider including Voco. Ring the demo line and run these five scenarios. You will learn more in fifteen minutes than from any amount of sales material.
The ordinary new enquiry. "I want to make a will." Does it capture enough that a fee earner could ring back and be useful?
The advice trap. "Do you think I have a case?" It should decline clearly and offer to have someone call you. If it offers a view, walk away.
The fee question. "How much do you charge for a divorce?" It should capture the question and route it, not answer it.
The distressed caller. Speak quickly, upset, and interrupt it. Does it stay coherent and get to a human?
The out-of-hours emergency. Call at 9pm and describe something genuinely urgent. What actually happens, and does anyone at the firm find out tonight?
You can run all five on Voco's demo line at 0333 043 6661, or use the live legal demo configured for a law firm.
What it costs
Voco charges 29p a minute ex VAT on pay as you go, with no monthly fee and no contract. Calls are billed by the second. On Voco's own observed data the average billed call runs about 1.9 minutes, so a typical enquiry costs around 55p.
For comparison, checked at source on 4 September 2026: UK human answering services publish entry prices from around £35 to £49 a month, and cover that includes evenings and weekends generally starts at £115. Several UK providers publish no rates at all and quote on request.
The arithmetic for a law firm is unusual, though, because the numbers are lopsided. If answering one additional enquiry a month converts to one additional matter, the cost of the service is not the number that decides it. Work out your own figure with the missed call calculator, then read the pay as you go rate.
Where this fits alongside your existing setup
Most firms do not replace their reception with this. They put it behind reception, so it catches overflow when the line is busy, and in front of the answerphone, so nothing reaches voicemail at all. The full picture of how Voco handles legal calls is on the legal answering service page, and the answering service for solicitors page covers practice-specific detail.
Common questions
Can an AI answering service give legal advice?
No, and it must not. A properly configured service refuses advice questions, captures what the caller asked, and routes it to a fee earner. Anything that offers a view on merits, time limits or prospects creates a duty the firm never intended to assume, and no cost saving is worth that.
Will callers know they are speaking to an AI?
Most will work it out, and being straightforward about it goes better than trying to disguise it. In practice callers care far more about whether the call gets them somewhere than about who answered. A caller who reaches an AI at 9pm and gets an appointment is better served than one who reaches a voicemail.
How does it handle a distressed or vulnerable caller?
The rule to set is early handoff. The service should recognise distress, avoid pressing for detail, take a safe contact number and route to a person quickly. In family matters it should ask whether it is safe to call back on that number before taking anything else.
Can it run a conflict check?
No. It captures the names and matter details a check needs, then hands them to your firm. It must never tell a caller the firm is able to act, because that is a decision only a qualified person can make once the check is done.
Where is the call data stored?
Ask every provider this in writing, including jurisdiction, retention period, who can access recordings and what happens on termination. Voco is a UK company handling UK call data and publishes its data processing agreement.
What happens to calls outside office hours?
They get answered at the same rate as calls at 11am. Out-of-hours is where the difference is largest for law firms, because an arrest, an accepted offer or a served notice does not wait for Monday.
How much does an AI answering service for a law firm cost?
Voco charges 29p a minute ex VAT with no monthly fee and no contract, so a typical enquiry costs around 55p. UK human answering services publish entry prices from around £35 to £49 a month, checked 4 September 2026, with evening and weekend cover generally starting nearer £115.
Does it work with our case management system?
Ask which systems specifically, and whether the integration writes a record automatically or emails a summary that someone retypes. The second is not an integration, and the difference shows up in how much admin time you actually save.
What if the AI cannot answer something?
It should say so plainly and route to a person rather than improvise. You set the rules for when a call transfers and when it takes a message, and getting those rules right matters more than anything about the voice.
Is this suitable for a firm of our size?
Volume matters less than call pattern. A sole practitioner who is in court three days a week loses proportionally more calls than a twenty-partner firm with a staffed switchboard. If your calls arrive while nobody can answer them, the size of the firm is not the deciding factor.
