Can AI help us close a file properly at the end of a matter?

Yes, for the checking part of it. An AI assistant can read a finished file end to end and tell you what is still outstanding, what was promised to whom, what money has moved and what the client was last told, which is the part most often done from memory at the end of a busy matter. The decisions about whether the file can actually close, and what happens to the money and the papers, stay with the fee earner and the firm's own procedures.

Why closing files is where risk collects

Most firms are good at opening files and reasonable at running them. Closing is where attention drops, because the work is done, the bill is out and the fee earner has already moved on to something else.

The problems that surface later almost always start here. An undertaking never formally discharged. A document still held that should have gone back. Residual balance sitting on client account. A final letter that does not say clearly that the retainer has ended. A deed in the safe with nothing on the file explaining why. A promise to chase something in six weeks that nobody diarised.

None of these are hard to spot. They are just scattered across a file that nobody wants to read again. That is exactly the kind of work an AI assistant is suited to: reading a large amount of material carefully and reporting what it found, with a page reference for each point.

What to ask the AI when you are closing

The useful approach is a short set of questions put to the whole file, not a single instruction to "close this matter". Questions worth asking:

• What undertakings were given on this matter, and does the file show each one discharged?
• What did we tell the client we would do, in the last three letters or emails, that does not appear to have been done?
• What documents are recorded as received from the client or a third party, and does the file show them returned or retained with the client's agreement?
• What deadlines or review dates were mentioned anywhere on the file that fall after today?
• What was the last position on costs, and what does the file say about any balance held?
• Does the file record the outcome of the matter clearly enough that a stranger could follow it?

Each answer should come back with the page it came from, so you can look at the source rather than take the summary on trust. Where the file simply does not say, you want to be told that, not given a plausible guess.

The same reading can produce a short closing summary: what the matter was, what was achieved, what was advised at the end and what remains with the client. That is useful if the client returns in two years, and useful again if the file is ever reviewed by an insurer or a regulator.

What AI cannot decide for you

It cannot decide the file is safe to close. Whether an undertaking is truly discharged is a judgement about its wording and the evidence of performance, and that judgement belongs to a qualified person who understands what was promised.

It cannot move money, send the closing letter or update the practice management system. Nor should it. The accounts position on client account in particular is governed by the firm's own records and its accounting rules, not by what the correspondence appears to show. Use the AI's reading of the file as a prompt to check the ledger, never as a substitute for checking it.

It also cannot tell you what your retention period should be. That depends on the type of work, what the retainer said, what the client agreed and the firm's own policy. AI can tell you what the file contains; the firm decides how long it keeps it and why.

Retention, destruction and the data question

Closing a file is a data protection event as much as a file management one. The papers you keep, you keep for a reason and for a period. The papers you destroy, you destroy on a defensible basis.

Two practical points. First, if you have used an AI assistant on the matter, decide what happens to that conversation when the file closes, and record the decision in the same place as the rest of your retention policy. The conversation is part of the record of how the work was done, so treat it as you would attendance notes rather than as something disposable.

Second, do not create a second copy of the file in a place your retention policy does not reach. Whatever tool you use should keep the firm's material where the firm can account for it, in the UK, separate from every other firm's material, and out of anything that trains a system for someone else.

A closing routine worth having

Keep it short enough that people actually do it. Run the file questions above, read the answers against the pages cited, check the ledger and the diary against what came back, deal with anything outstanding, then write the closing letter and record the retention date. The AI shortens the reading, not the deciding.

Where Alesis fits

Alesis is an AI assistant for UK law firms, made by Alesis.ai Limited and used through the browser, with one conversation for a matter. It answers questions about a matter from the matter's own papers and names the page each answer came from, and where the papers do not say, it says so rather than guessing. It prepares drafts for a qualified person to review and sign off, and it does not file, serve or email anything. The firm's information is held in the UK, processed only in the UK and the EU, kept apart from every other firm, and never used to train anything for anyone else.
