Matter Closing and Disengagement Letter
When the work under an engagement is finished, settled or terminated, so the client knows in writing that the representation has ended and which deadlines are now theirs.
Many representations never formally end. The last task gets done, the final invoice goes out and the file goes quiet, while the client assumes the firm is still watching for the next deadline. That ambiguity extends the period in which the firm can be blamed for something it never agreed to handle, and it leaves trust balances, original documents and the file itself in limbo.
This prompt drafts a closing letter from your engagement letter and closing notes. It confirms the work completed by quoting the original scope, states the date the representation ended, lists every open item or future deadline that is now the client's responsibility, explains the trust balance and final invoice, confirms the return of property and states your file-retention period. It then flags anything in your notes that went beyond scope, any deadline without a date and any inconsistency with the engagement letter.
Claude only knows the deadlines and balances you give it, so the letter is only as complete as your closing notes and trust records. It does not calculate future deadlines or decide how long your jurisdiction requires you to keep files. You remain responsible for reconciling the trust account, confirming the retention rules that apply and reviewing the letter before it goes out. Treat the output as a draft for attorney review.
The Prompt
I am closing a matter for a client of [FIRM NAME] and need a disengagement letter that ends the representation clearly. <document name="engagement_letter"> [PASTE THE ENGAGEMENT LETTER OR SCOPE OF REPRESENTATION] </document> <document name="closing_notes"> [PASTE CLOSING NOTES: WORK COMPLETED, FINAL RESULT, OPEN ITEMS, DEADLINES, PROPERTY HELD] </document> Details: - Client name and address: [CLIENT] - Matter: [MATTER NAME] - Final invoice status: [PAID / OUTSTANDING AMOUNT / FINAL INVOICE ENCLOSED] - Trust account balance and handling: [AMOUNT AND HOW IT WILL BE DISBURSED OR "NO BALANCE"] - Original documents or property to return: [LIST] - File retention policy: [RETENTION PERIOD AND WHAT HAPPENS AFTER] Draft a letter that: 1. Confirms the work completed, matching the scope in the engagement letter. Quote the scope language you rely on. 2. States that the representation in this matter is concluded as of [DATE]. 3. Lists every open item or future deadline that is now the client's responsibility, in a short bulleted list, using only dates stated in the closing notes. 4. Explains the trust balance, final invoice and return of property. 5. States the file-retention policy as [RETENTION PERIOD] and how the client can request the file. 6.

Tips
- •Paste the engagement letter so the closing letter tracks the original scope. Most disputes over whether a representation ended turn on scope.
- •Make the client-owned deadline list concrete: renewals, compliance filings, payment dates under a settlement. If a deadline has no date in your notes, resolve it before sending rather than leaving it vague.
- •Reconcile the trust ledger before sending. The letter should match the ledger to the cent.
- •Use the same language each time in a Claude Project so every closed matter gets a consistent letter.
- •Treat the output as a draft for attorney review, confirm your retention policy against your jurisdiction's rules and your malpractice carrier's guidance, and verify any lease, agreement or rule section the letter cites.
Frequently Asked Questions
Why send a closing letter if the case is obviously over?
Because it is often obvious only to the lawyer. Clients may assume the firm is still tracking renewals, appeal windows or settlement payments. A written closing letter fixes the end date of the representation, transfers named deadlines to the client and documents the handling of trust funds and property. If a dispute arises later, the letter is the clearest evidence of what you agreed to do and when you stopped.
Should the letter list deadlines the firm did not calculate?
No. The prompt lists only deadlines with dates stated in your closing notes and flags any deadline mentioned without a date. Adding new deadlines from memory risks giving the client a wrong date in writing. If an important future date has not been calculated, decide whether to calculate it before closing or tell the client expressly that they should get advice on it.
How long should I say we keep the file?
Use your firm's written retention policy, inserted as the retention period placeholder. Retention periods vary by jurisdiction, by type of matter and by what your malpractice carrier recommends, and some files, such as those involving minors or trusts, may call for longer periods. Claude will not pick a period for you. Confirm the rule that applies before you send the letter.
Can I use this for a withdrawal before the matter is finished?
Partly. The structure works for listing open items and returning property, but withdrawal in the middle of a matter, especially in litigation, can require court permission and raises different duties to protect the client's interests. Use this prompt for matters that are complete or settled, and handle mid-matter withdrawals under your jurisdiction's withdrawal rules with a separate, carefully reviewed letter.
