Closing a matter: the checklist that protects the firm (and the client) when the file ends

Every serious law firm knows how to open a matter: engagement letter, conflict check, client identification and planning. Far fewer have written down how to close one. Yet closing is where complaints concentrate: documents never returned, client fund advances never reconciled, final fees chased late and badly, and clients unsure whether their matter ended or is still open. A poorly managed close turns impeccable work into a grievance; a well-run one is the best possible end to the client experience and the gateway to the next engagement. It is the companion piece to our matter-opening checklist.

Why closing gets neglected

The cause is structural: closing is never urgent. Nobody calls the firm demanding that their file be archived, so the team prioritises whatever has a deadline and "finished" files drift into administrative limbo. The answer is not willpower but process: making closing a phase of the matter, with an assigned owner and a checklist as mandatory as the opening one.

The eight points of the closing checklist

First, the outcome check: what was achieved, what remains open and whether there are appeals or future actions the client should know about, with their deadlines. That assessment must be in writing.

Second, the formal closing communication: a letter or email confirming the engagement has ended, summarising the outcome and making clear the firm assumes no ongoing monitoring unless expressly agreed. This document is the firm's main protection against future claims over limitation periods or subsequent events.

Third, returning original documents: deeds, contracts and powers of attorney go back to the client against receipt. Whatever is kept as a copy must be identified.

Fourth, the financial reconciliation: final invoice itemised as agreed in the engagement letter and, above all, immediate return of any surplus from advances on client funds and disbursements — an obligation directly tied to the discipline of the separate client funds account. Unpaid final fees must be handled now, not months later; for those cases, recall the order-for-payment procedure for recovering fees.

Fifth, archiving: complete file, minimum index, closing date and scheduled destruction date in line with the firm's retention policy and data protection rules. An archive with no review date is a warehouse, not an archive.

Sixth, updating systems: marking the matter inactive, closing tasks and reminders, and noting any future dates — contract expiries, appeals — that were expressly agreed to be monitored.

Seventh, the internal quality review: what went well, what cost more than budgeted and what would be done differently. Ten minutes per matter feeds process improvement better than any consultancy.

Eighth, the honest commercial farewell: thanks, availability for future matters and, only where the relationship supports it, a satisfaction question or a referral request. No pressure: professional ethics and common sense set the tone.

Closing as management data

One detail separates the amateur firm from the professional one: closings are counted. Knowing how many matters closed each month, the average time from outcome to closure and the final billing lets the firm detect zombie files — open in practice, finished in law — that inflate the team's apparent workload and distort any forecast. That count also feeds the annual process review and gives the firm a true picture of its activity by practice area.

How to implement it without friction

The checklist works if it lives where the matter lives: as a template in the case management system or, at least, as a shared document per practice area. Assign a closing owner when a matter enters its final phase and review "finished but unclosed" files monthly, just as deadlines are reviewed. A firm that closes well not only protects itself: it discovers dormant engagements inside its own client base. More resources in the firm processes section.
