The client rings at ten past four with a question that sounds simple. Did the firm warn her in March that the deadline for her claim was approaching, or was it April, and did the letter say what she remembers it saying? The partner knows the answer sits somewhere on the file, among eleven hundred documents, two changes of fee earner and a run of emails that nobody filed in order.

Take an illustrative firm where each partner spends forty minutes a day hunting for a fact they know is on a file. At a charge out rate of £300 an hour, that is £200 a day, and across a working year of 220 days it comes to £44,000 for each partner. Little of it reaches a bill, because no client expects to pay for the firm to find its own letter. The time goes down as a write off, or it never gets recorded at all.

The delay costs something too. A client who waits two days for an answer to a plain question starts to wonder what else the firm has lost track of. Counsel waits for instructions while someone works out which version of the settlement agreement the client signed, the draft of 4 June or the engrossment that followed it, and the hearing date does not move to suit the search.

The greater danger lies in the shortcut. Faced with a full diary and a file that resists searching, a partner answers from memory. Memory says the other side conceded causation in their letter of response, when the letter conceded breach and reserved its position on everything else. Anyone who has sat in the county court has watched an advocate tell the judge that a document was agreed, and then watched the bundle say otherwise. The judge decides on the papers, and a client advised from recollection has been advised on something other than the papers.

Answering from the paper

The remedy starts with habits that cost nothing to adopt. Keep a living case summary at the front of every file and update it at each milestone, so that the issue of proceedings, an offer, a concession and a change in instructions each earn a line with a date and a reference to the document that records it.

File notes do more work when they say where the important papers sit. An attendance note that records the client's instructions on settlement should name the letter that confirmed them and the folder that holds it. Consistent naming helps in the same way. If every piece of correspondence carries its date, its author and its subject in the same order, and every attendance note follows one format, a search finds what it should in seconds instead of turning up forty near matches.

Then make it a rule that nobody answers a client, the other side or the court on a point of fact without the paper in front of them, and that the answer cites it. “Our letter of 14 March, second paragraph” settles a dispute about what the client was told before it starts. It also gives a supervisor something to check, which matters because the SRA expects a firm to keep proper records of its work and to supervise the people doing it. A file that only one person can find their way around is hard to supervise and harder to hand over.

Where Bracton fits

Bracton is an agentic AI case management system for law firms in England and Wales, and its assistant, Henry, works from the same principle. Ask him a question about a matter and he answers from the papers on that file, naming each paper he relies on and the page, so the fee earner checks the source instead of taking the answer on trust. A follow up question carries on as one conversation on the same file, and each answer is recorded on it, which leaves a trail a supervisor can read.

For larger reviews, you can set Henry to work in the background on up to three hundred papers and twenty questions, and he reads them into a table with one column to each question. He works under the permissions the firm gives him. What he reads stays where the firm holds it, nothing the firm sends trains a model, and everything he drafts waits for a qualified fee earner to approve it. A firm ready to move can take the full Bracton platform, and a firm that wants to keep LEAP, Clio, Proclaim or another system can add the Bracton AI Assistant to the one it runs today.

The way to judge this is on your own files, with the questions your clients ask you. Pick the matter that cost you the most searching last month, and to see Henry answer it from its own papers, book a client account review.
