Every practice files by matter. It is opened with a number, it carries its own correspondence, its own pleadings, its own bill, and it closes. This is not a bad system. It is the only system that works for billing, for court, and for knowing what you are actually working on.
It is also, quietly, the reason a particular kind of question takes half a day.
The question is never matter-shaped
A client calls. Their group is negotiating a supply agreement and the other side has pushed back an indemnity clause. The client says — reasonably, and with complete confidence — "you advised us on exactly this two years ago."
They are right. You did. It was a different entity in the same group, it was an advisory matter rather than a dispute, the associate who drafted the note has since moved to a firm in another city, and the matter is closed and archived.
Nothing is lost. Everything is filed. And you still cannot answer the question in the two minutes the client thinks it should take, because the file is organised around the thing you did and the question is organised around the person you did it for.
Four questions the matter file cannot answer
What have we already told them? The most expensive question in a practice. Advice given in one matter constrains what you can comfortably say in another, and there is no reliable way to surface it except for somebody to remember. Most firms discover the earlier note after they have taken the later position.
What did we actually agree about how we work? Fee arrangement, who at the client is authorised to instruct, whether they wanted to be copied on correspondence, the discount that was extended once in 2024 and has been assumed ever since. None of this belongs to a matter. All of it lives in email, and gets re-litigated every time a bill goes out.
What was said, as opposed to what was filed? Instructions arrive by phone and on WhatsApp. The file note is written afterwards, if there is time, and the version of the instruction that ends up on the file is the version you reconstructed. When the client later says "that is not what we asked for", both of you are arguing from memory, and one of you is the professional.
Who knows this client? The honest answer in most practices is one person. When that person leaves — and associates leave — what walks out is not the files. It is knowing which file matters.
None of these are filing failures. The matter file is doing its job correctly. It simply was never designed to be a client's history, and asking it to be one is why the search takes half a day.
The gap is where instructions actually arrive
There is a second reason this gets harder every year, and it has nothing to do with filing systems.
Instructions no longer arrive in a form that files itself. They arrive as a voice note at 9pm. As a photograph of a signed page with the words "proceed" underneath. As a forwarded thread with one line added at the top. As a message in a group that contains the client, their finance head, and someone whose role nobody in your office has ever established.
The practice then does one of two things. Either somebody converts the message into a file note — accurately, eventually, sometimes — or the message stays where it landed, on a phone, and the file records only the output. The instruction that produced the draft is not in the same place as the draft.
That is fine until somebody asks why the draft says what it says.
Keep the matter file. Add a client record beside it.
The instinct at this point is to reorganise, and that instinct is wrong. Matter numbering is load-bearing — for conflicts, for billing, for court, for professional obligations. Nothing here is an argument against it.
The argument is that a matter file and a client record are two different objects, and most practices only keep one.
A matter file is a closed, dated container for one piece of work. It has a beginning and an end. It is the right unit for everything a matter needs.
A client record is open-ended and spans everything: the instructions, the advice given across matters, the arrangement about fees, the correspondence that never belonged to a matter, and — this is the part that decides whether it is useful — the source document sitting beside each of them.
The second one is what answers the call about the indemnity clause. It is also the thing that survives an associate leaving, because it belongs to the practice rather than to whoever happened to run the file.
Three tests worth running on your own practice
Pick a real client. Not the well-organised one — pick the one who calls the most.
- The cross-matter test. Take a question from a live matter whose answer
- The instruction test. Open any draft sent to a client in the last month.
- The departure test. Assume the associate who knows this client best
sits in a closed one. Hand it to someone who did not work on either. Can they find it? If the route to the answer is "ask whoever ran that file", the answer is not in the practice; it is in a person.
Can you produce the instruction that authorised it — the actual message, not a note describing it — in under a minute? This is the one most firms fail, and it is the one that matters when the instruction is disputed.
resigns on Friday. On Monday, what does the practice no longer know? Every item on that list was never really in the practice.
Most firms fail at least two. That is not a comment on how they are run — it is what happens when the filing system is matter-shaped and the questions are client-shaped, which is true of essentially every practice in the country.
The record is the part that compounds
Matter files accumulate. That is different from compounding. A closed file is worth roughly what it was worth on the day it closed, and slightly less each year as the people who remember it move on.
A client record gets more valuable the longer it runs, because the questions you can answer from it are questions about history: what did we advise, when, on whose instruction, and where is the page that says so. In year one that is convenience. In year five it is the reason a client does not need to explain themselves to you, which is most of what they are actually paying for.
Kognora gives a practice one record per client that runs across matters — instructions, correspondence, drafts and documents held together — and answers questions from that record with the source document attached, so an answer about a two-year-old note arrives with the note. Each client's record is isolated from every other, client data is not used to train anyone's model, and nothing is sent to a client without a person reading the draft and pressing send. Kognora does not practise law, does not run your conflict checks and does not replace your matter numbering; it is the memory around them. The plain version of what it does and refuses to do is written out here, and the filing side of the same problem is in where did the client send that document?
