A client rings in March to say a supplier has walked away from a contract. The fee earner records it in an attendance note, opens a file and writes to the other side. Nothing much happens for a while, the parties talk, an offer is refused, and proceedings are issued in November. Somewhere in those eight months the client's mail system did what it had been configured years earlier to do, deleting anything older than, say, twelve months on a rolling cycle. The exchanges from the first weeks of the relationship, when the parties were still agreeing what the supplier had promised, went with it. Nobody told the system to stop.
The duty to preserve documents in England and Wales arises when litigation is reasonably in contemplation, not when a claim form is issued. Every litigator knows that. Firms treat preservation as a step in the litigation process rather than a step at the point of instruction, so the letter goes out when someone starts thinking about disclosure. By then the client has run its ordinary retention and deletion routines for months against material that was already protected. The gap between contemplation and issue is where the loss happens, and it goes unnoticed at the time, because nobody receives a notification that a mailbox has been emptied.
The delay has understandable causes. Early on the matter looks like it will settle, the file is thin, and a formal instruction about preserving evidence reads to the client as a signal that their solicitor expects a fight. The cost of getting it wrong falls much later. A party to litigation is expected to account for what it holds and to explain what has been lost and why, and an unexplained gap does more damage to a witness than the content of most documents that survive. Credibility suffers, adverse inference becomes available, and costs consequences follow the party that cannot explain the gap.
A general letter preserves nothing
The instruction most firms send, when they send one at all, asks the client to retain all documents relevant to the dispute. A client reading that thinks of the contract file and the folder of correspondence on the shared drive. It does not occur to them that the phrase reaches an automated retention rule set by an IT contractor years ago, or the mailbox of the operations manager who left in June, or a messaging group in which two site managers agreed what had gone wrong on the day it went wrong.
So the instruction has to name the systems. Email and its archive, the shared drive, the accounting and job management systems, personal devices used for work, messaging applications, backup media and cloud storage each need dealing with by name, and the automatic deletion cycle needs suspending in express terms, with the person who administers it told to do it. Leavers deserve their own paragraph, because a closed and reclaimed mailbox is the most common permanent loss of all and the one nobody thinks to mention. Address it to a named person at the client with authority to direct their IT function, not to a general inbox. Then record what went out, who acknowledged it, and what the client said about the systems it holds.
The discipline across a caseload
One well drafted instruction on one file is not a system. A preservation instruction sent at the outset goes stale when the client migrates its mail to a new provider, retires an old case system, or loses the employee whose account holds the material that matters, so it has to be revisited during the life of the matter and confirmed whenever the client's arrangements change.
This is where the discipline breaks, because no partner can say from memory which of the firm's live disputes has a preservation instruction on file and which does not. Ask the question in a supervision meeting and the honest answer is that somebody would have to look. Looking means opening every disputed matter in turn, and nobody has that afternoon.
The Bracton AI Assistant plugs into the case management or CRM system your firm already runs, LEAP, Clio or Proclaim among them, and reads every live matter overnight rather than the one file open in front of a fee earner. Applied here, that read marks the matters where a dispute has been recorded and no preservation instruction sits on the file, then drafts the instruction, named to the client contact and to the systems that matter, for the responsible fee earner to check, amend and sign. Nothing leaves the firm without that signature, the hosting is in the UK, and your client data is never used to train a model. A firm free to change the system underneath takes Bracton itself instead, the case and client management platform beneath the assistant.
Test this against your own files. Take the disputes your firm opened this year and see how many carry a written preservation instruction and a record of who acknowledged it. To find out which of your live matters have neither, book a client account review.
