Legal Matter Closing Checklist Template

A matter that is finished but never formally closed keeps causing trouble: a residual balance sitting in client account, an undertaking nobody discharged, a client who thinks you are still watching their deadlines.

Closing a file is the last piece of work on a matter and the easiest to leave half done. This free legal matter closing checklist is for law firms of any size and for in-house legal teams. It takes a matter from “the work is done” to an archived file with a destruction date: deadlines and undertakings cleared, a final bill, client money returned, a closing letter that ends the retainer, originals handed back, the conflicts record updated and retention set. Three questions at the start add the tasks for client money, for a retainer that ends early, and for England and Wales or US rules.

Closing a Matter, Ending the Retainer, Destroying the File

Firms often treat “closing the file” as one step. It is really three events, often years apart. Mixing them up is how a client ends up believing the firm is still acting, or how a file is shredded while a claim could still be brought.

The closing letter does most of the work. Malpractice insurers and bar guidance recommend a written disengagement or closing letter, because without one a client may reasonably think the relationship, and the firm’s duty to watch deadlines, continues. The letter also marks when the client becomes a former client for conflicts purposes.

Step 1

The matter closes

When: the work is complete, or the retainer ends early.

What happens: deadlines and undertakings cleared, final bill, money returned.

Risk if skipped: money and obligations left with nobody watching.

Step 2

The client becomes a former client

When: the retainer ends and the client is told so in writing.

What happens: conflicts record updated; confidentiality continues indefinitely.

Risk if skipped: the client assumes you are still acting.

Step 3

The file is destroyed

When: the retention period set at closing runs out.

What happens: a destruction review, then secure destruction recorded against the matter.

Risk if skipped: files kept forever, or destroyed while the firm still needs them.

This checklist covers the first two steps and diarises the third. It is the counterpart of the Legal Case Intake Process Checklist: what intake opens, closing should shut.

What to Do With Each Thing at Closing

The rules behind a file closing are spread across accounts rules, conduct codes, court rules and anti-money laundering law. US rules are set state by state, mostly adapted from the ABA Model Rules, so check your own state’s version. This is a starting point, not legal advice.

ItemWhat to doEngland & WalesUS (ABA Model Rules)
Client moneyBill, take costs, return the balance promptlySRA Accounts Rules 2019: bill or written notice before taking costs (rule 4.3); return money promptly once there is no proper reason to hold it (rule 2.5)Rule 1.15: promptly deliver funds the client is entitled to; state trust account rules apply
Untraceable balancesRecord attempts to trace the clientBalances of £500 or less per matter can go to charity under SRA conditions; larger sums need SRA authorisationUsually escheat to the state under unclaimed property law after a dormancy period that varies by state
UndertakingsDischarge or get a written release before closingSRA Code paragraph 1.3: perform all undertakings within the agreed or a reasonable timeCheck state rules and any written commitments given
Original documentsReturn against a receipt, or record safe custodyOriginals sent by the client generally belong to the clientRule 1.16(d): surrender papers and property the client is entitled to

Why Close Matters in CheckFlow?

1

No file closes without sign-off

The cashier approves the final bill and client account position before money moves, and the supervising partner approves closure. Both approvals halt the checklist until given.

2

Only the tasks this matter needs

Three dropdowns decide what appears: client account tasks only where the firm holds money, withdrawal tasks only where the retainer ended early, and the right records task for the jurisdiction.

3

A closing record that stands up

The closing letter, nil ledger and receipts for returned originals sit on the tasks that produced them, and the audit trail shows who did what and when, ready for a file review.

CheckFlow is not a case management, legal accounting or document management system. It runs the closing process around those tools, so every fee earner closes files the same way. CheckFlow for law firms shows how practices use it for intake, closing and the recurring compliance work in between.

Accountants, agencies and consultancies ending a client relationship can use the Client Offboarding Checklist, which adapts this process for firms without client account or court rules.

Frequently Asked Questions

What should a matter closing checklist include?

A check that the work is complete and no court deadline or undertaking is outstanding, the dates the client must act on after closing, a final bill, the return of client money, a closing letter that ends the retainer, returned originals, an updated conflicts record, a retention period with a destruction date, and a supervising partner’s sign-off. If the retainer ended early, add coming off the record and transferring the file.

What should a closing letter to a client say?

That the matter is closed and the firm is no longer acting, from a stated date. What the firm will not do from now on, such as monitoring deadlines or updating its advice if the law changes. The dates the client must act on, like limitation or renewal dates. What happens to originals and any money held, and how long the file is kept before destruction. Keep it plain; it may be read again years later.

What happens to money left in client account at the end of a matter?

It goes back promptly to the client, or the third party it is held for. In England and Wales, rule 2.5 of the SRA Accounts Rules 2019 requires return as soon as there is no longer any proper reason to hold it; untraceable balances of £500 or less per matter can go to charity under SRA conditions, and larger sums need SRA authorisation. In the US, ABA Model Rule 1.15 requires prompt delivery, and unclaimed funds follow your state’s unclaimed property rules.

How long should a law firm keep a closed file?

There is no single answer. In England and Wales many firms keep most files for at least six years, the main limitation period under the Limitation Act 1980, and longer for property purchases, wills and trusts; anti-money laundering records have their own five-year rule. In the US it depends on your state. Set periods by matter type and write the one that applies into the closing letter.

Who owns the file when a matter closes?

Usually both of you, in parts. The Law Society’s practice note for England and Wales says originals the client sent, final versions of documents and third-party correspondence generally belong to the client, while working papers, drafts, internal notes and accounting records generally belong to the firm. Engagement terms can change this. In the US it varies by state, and many treat the file as the client’s.

Why does a closed client still matter for conflicts?

Because duties to former clients outlast the retainer. ABA Model Rule 1.9 stops a lawyer acting against a former client in the same or a substantially related matter without the former client’s informed consent, confirmed in writing. In England and Wales the SRA Code keeps former clients’ affairs confidential and restricts acting against a former client whose material confidential information the firm holds. Mark the client as former; never delete the record.
