Repeat instructions and referral sources in law firms
The people most likely to instruct a firm are people who already have. Most firms know this, and very few can say how many of last month's instructions came from them.
The most reliable source of new instructions for most law firms is people who have used the firm before, and people those clients have told. The Legal Services Consumer Panel's 2025 tracker survey of 3,750 legal services users found that having used the provider before (19 per cent) and a recommendation from family or friends (18 per cent) were the two most common ways people chose their provider. Yet most firms cannot say what share of last month's instructions came from former clients or referrers, because nobody asked when the file was opened. This post sets out how to measure it, and what to do to earn more of it.
It is part of our series on revenue operations for law firms.
Why is this the cheapest revenue a firm has?
Because the trust is already built.
A returning client already knows how the firm works, what it costs and who to ask for. A recommended client arrives with a friend's account of the firm in their head. Both convert more easily than a stranger who found the firm in a search result, and neither needed advertising.
There is a caveat, and the same survey shows it. Even people who received a recommendation did not simply pick up the phone: 57 per cent still looked for more information about the provider before contacting them. So a recommendation brings somebody to the website and the phone line, and the firm still has to answer, and still has to look credible when it does. A referral wasted on voicemail is the most expensive missed call there is. What that costs is set out in what missed enquiries actually cost a UK law firm.
Where do a firm's instructions actually come from?
Broadly, from six places. Use these as the options in the source field when a matter is opened:
- Returning client. The same person or business, a new matter.
- Cross-referral. An existing client of one department instructing another, for example a conveyancing client making a will.
- Personal recommendation. A client, friend or family member told them.
- Professional referral. An accountant, estate agent, IFA, another law firm, a union, a charity.
- Search and online. The firm's website found through a search engine, a review site or a directory.
- Other. Advertising, events, walk-ins. Record what it was.
Keep the list short. Six to eight options is enough. A list of thirty produces "other" on half the files.
How do you capture the source without extra admin?
Ask once, at the right time, and write down what the client says.
The right time is the first contact, not the opening of the file. "How did you hear about us?" is a natural question on a first call. By the time the client care letter is going out, nobody remembers to ask, and asking in a form produces "internet" from people who were in fact recommended by a friend and then looked the firm up.
Then carry the answer through to the file. If the enquiry note has a source field and the matter opening form copies it, it is typed once. If it lives only in a receptionist's notebook, it is gone.
Two refinements help:
- Record the name of a referrer, not just the type. "Referred by an accountant" is useful. "Referred by the accountant at a named local practice" is the start of a relationship you can look after.
- Record the department that referred for cross-referrals. It is how you find out which teams send each other work and which do not.
What should a firm do with the data?
Three things, each simple.
Count it monthly. Share of new instructions by source, by team, on a rolling three-month basis. It belongs on the page in the KPIs a managing partner should actually watch.
Thank referrers. Professional referrers who send work and hear nothing back stop sending it. A short note to say the client instructed and you will look after them is often enough. What you may say depends on client confidentiality and any consent the client has given, so check before sharing any detail about the matter.
Look at the gaps. If the private client team receives no referrals from the conveyancing team, and the conveyancing team handles hundreds of purchases a year, that is a conversation to have.
How do you win more repeat instructions?
Mostly by being remembered, and by being easy to reach.
Close the matter properly. A closing letter that says what was done, what the client might need in future, and who to contact next time. Most clients forget the name of the firm that did their last conveyance. A letter they keep fixes that.
Stay reachable. When a former client calls the main number three years later, somebody should answer, and ideally know they are a former client. That is harder than it sounds if the firm's records sit only in the practice management system and reception cannot see them.
Keep the client informed during the matter. A client who felt ignored during their matter will not come back, whatever the outcome. The mechanics are in where enquiries get lost between reception, fee-earners and billing.
Ask for reviews and feedback, carefully. A short feedback request at the end of the matter helps you improve, and some clients will leave a public review. Follow the SRA's rules on publicity, and never incentivise reviews.
How do you get departments to refer to each other?
This is the one most firms say they want and few manage. The obstacles are ordinary:
- Fee-earners do not know what other teams do, in enough detail to spot the moment.
- There is no reward for referring, and a small risk: if the other team lets the client down, the referrer's relationship suffers.
- Nobody notices the moment. The trigger for a will is a house purchase, a marriage, a child, a divorce. Those facts are in the file, but nobody is looking for them.
What helps:
- Agree a short list of triggers per team, written down. For example: property purchase suggests a will and lasting powers of attorney; divorce suggests updating a will; a business sale suggests personal tax and estate planning.
- Make the referral a warm introduction, not "call our wills team". The client hears from a named person in the other department, who already knows the context the client has agreed to share.
- Report cross-referrals by team so the partners can see them. What gets counted gets done.
- Close the loop. Tell the referring fee-earner the client instructed.
One more thing makes cross-referral work: timing. A will suggested in the middle of a stressful purchase is noise. The same suggestion in the closing letter, when the keys have been handed over and the client is relieved, lands as care. Build the trigger into the moment the matter ends, not the moment the fact appears in the file.
Cross-referral is not a sales campaign. It is noticing that a client has a need the firm can meet, and making it easy for them. Done well, clients experience it as service.
A worked example
The figures below are invented to show the arithmetic. They are not a benchmark and describe no real firm.
A firm opens 100 new matters a quarter. After three months of recording the source, it finds:
- Returning clients: 12.
- Cross-referrals between departments: 4.
- Personal recommendations: 20.
- Professional referrers: 18, of which 11 came from three local estate agents.
- Search and online: 34.
- Other: 12.
Three things jump out. Cross-referrals are low for a firm with both a conveyancing and a private client team. Most professional referrals come from three sources, which is a concentration risk if one of them changes firms. And the "other" category is too big, which means the options are wrong or the question is being asked badly.
The firm's actions are equally concrete: a trigger list between conveyancing and private client, a quarterly call with each of the three estate agents, and a rewrite of the source options. None of it needs new software.
How do you look after professional referrers?
Professional referrers (accountants, estate agents, financial advisers, other firms, charities) are a small number of people who can send a lot of work. They behave like a client portfolio, and deserve the same care.
A light-touch routine that works in firms of any size:
- Keep a short list. Everybody who sent a matter in the last twelve months, with the name of the person, their firm, and how many matters they sent.
- Assign an owner for each. Usually the partner or senior fee-earner who has most contact with them. One name, not a department.
- Acknowledge each referral promptly, within the limits of confidentiality and what the client has agreed you may share.
- Look at the list quarterly. Who has gone quiet? A referrer who sent four matters last year and none this year has usually found somebody else, and a coffee is a cheap way to find out why.
- Make it easy to refer. A named person and a direct number, and a promise that the referred client will be called back quickly. A referrer's reputation is on the line when they send somebody, and a client who could not get through reflects on them.
That last point is the one firms underestimate. A referrer does not see your legal work. They see whether their client was answered and looked after. If the answer is no, the next referral goes elsewhere, and nobody tells you.
What should you record about a returning client?
Enough that whoever answers can recognise them and route them properly, and no more than the firm needs.
- That they are a former client, and of which department.
- Who acted for them, so the call can go to somebody they know if that person is still at the firm.
- When the last matter closed.
Keep it proportionate and in line with the firm's data protection and retention policies. The point is not to build a marketing file. It is that a client who rings back after three years should not be treated as a stranger.
What does this have to do with the phone?
More than it seems.
A recommended client, or a returning one, almost always makes first contact by phone or email. If that contact goes unanswered, the firm has spent years earning a recommendation and lost it in one evening. The first contact is also the best moment to ask the source question, and to recognise a returning client.
Where WasilX fits
Cam, our AI Engagement Coordinator, takes calls on the firm's line at any hour, says it is AI, asks how the caller heard about the firm as part of the questions the firm sets, and passes a summary to the right fee-earner with the source already written down. That means a referral who rings at 7pm is taken and written down, and the source field is filled in while the answer is fresh. Each fee-earner's personal assistant drafts matter updates for the fee-earner to approve, which is where most of the goodwill behind a repeat instruction is earned or lost. Cam never gives legal advice.

Frequently asked questions
What is a referral source in a law firm? The person or channel that brought a client to the firm: a former client, a friend, another professional, a search engine. Record it when the enquiry arrives.
Can we pay referrers? Referral arrangements and fee sharing are regulated, and some are prohibited in certain types of work. Check the SRA's rules before agreeing anything.
How many source options should we use? Six to eight. Long lists make people choose "other".
