A probate file opens in February with a funding story built on the sale of the deceased's flat, identification completed and the risk assessed as low. In September a payment arrives in the client account from a company nobody on the file has heard of, say £240,000, and it is receipted and allocated without a question, because nothing in the day's work asks anyone to read what the client said in February.
The enquiry you make at the start answers a question about the client as they were that day. Matters run for months and plans change. A sale falls through and bridging takes its place, a relative steps in, a business account is used because the personal one is frozen, or the sum that lands is larger than the funding narrative supports. The difficulty is that the change arrives in accounts while the story it contradicts sits in the matter file, read by different people at different times.
The ledger and the file have to be read against each other
The cashier who receipts a payment sees a payer name, a reference and an amount, which is enough to post it and rarely enough to know it is wrong. The fee earner who remembers the client describing years of savings at a high street bank is not looking at the client account that morning, and by the time the money surfaces on a completion statement it has sat in the balance for weeks. Both halves of the check exist in your firm, and nobody holds both.
The fix starts with a rule that money is not applied before it is understood. Where a receipt does not match what the file says about funding, hold it, and make holding a defined state with a name and an owner rather than inaction. That works only if fee earners record the expected source and route of funds where the accounts team reads it, concretely enough to test against a remittance advice.
A proper record is not a box ticked against the words source of funds verified. It sets out what you asked, who answered, what you were shown, when you saw it, and why the fee earner was satisfied that the answer accounts for the money that arrived. Where the explanation differs from what the client said at the outset, say so rather than replacing one narrative with the other. The money laundering regime requires ongoing monitoring of the business relationship and scrutiny of transactions through its course, and you have to evidence the enquiry rather than assert that one happened. Acting on funds you do not understand exposes the firm and the individual who handled them.
An escalation route works only when the person lowest in the chain can use it without permission. A cashier should be able to put a receipt in front of a named person, normally the money laundering reporting officer, without first persuading the fee earner whose file it is. Give it a time limit, require a written outcome on the matter, and audit the outcomes rather than counting referrals.
Make the check survive past March
What defeats the discipline is volume. A firm carrying four hundred live matters receipts payments every week, and asking a cashier to test each one against a funding note written months earlier by somebody else produces a check done properly in March and skipped in November. The comparison itself is mechanical, with a definite answer whenever both sides sit in the same place.
This is a large part of what the Bracton AI Assistant does when it connects to the case management system a firm already runs. It reads every live matter overnight, drafts the routine work and flags the files that have drifted. Working through another vendor's interface, the assistant sees what that interface exposes, normally matters, documents, correspondence, key dates and time records, while the ledger is sometimes thin or out of reach, which matters most here, because a funding narrative means little until you set it beside the money that arrived. Inside Bracton, the case and client management platform, there is no interface in the way and the ledger sits alongside everything else, so a receipt from a payer who appears nowhere in the retainer reads as a mismatch on the night it lands. It surfaces the mismatch and a qualified person decides what it means. It never contacts your client, and its output is filed inside the host system only once a qualified fee earner approves it.
Take twenty open matters at random, pull the client account entries, and ask the fee earner to explain every receipt against what the file records about funding. The ones that take a phone call to answer are the ones worth your attention, and if you want the same exercise run across every live matter you hold, book a client account review.
