Written by Client care · Closing letters · Former-client duties
A closing letter is not just administrative housekeeping. It can mark the end of the active instruction, confirm what work has been completed, explain what remains outside scope, and reduce later disputes about whether the firm still owes live retainer duties. But a closed file does not erase confidentiality, former-client risk or the need to explain a later adverse instruction.
Publication snapshot
This article uses a named concern involving Burnetts Solicitors as a case-study prompt for a wider professional-conduct question: why clear closing letters matter, and why former-client duties cannot be reduced to the phrase “the retainer had concluded”. It does not present disputed allegations as findings. It argues for better retainer-closure discipline, clearer client-facing records, and more transparent conflict analysis where a later instruction is said to touch information or assets from an earlier will or estate-planning matter.
Reader note: this article is public-interest commentary and practical legal education. References to Burnetts Solicitors, will drafting, closing letters, former-client duties, business assets, landlord disputes, conflicts, confidentiality and professional conduct are analysis of concerns raised. They should not be read as findings of fact, misconduct, dishonesty, unlawful conduct, fiduciary breach, negligence or professional wrongdoing by any named person, firm, client, landlord, regulator or public body unless established by a competent court, tribunal, regulator, ombudsman, inquiry, audit report or official decision.
Why closure records matter
The solicitor-client relationship begins with scope. It should also end with clarity. A client should know what work was agreed, what work was completed, what remains outside the retainer, what documents are held, what future steps remain their responsibility, and whether the firm is continuing to act.
That matters because uncertainty about closure can become more than a billing or administration issue. It can affect expectations about loyalty, confidentiality, future instructions, file access, limitation, storage, conflict checks and whether the client reasonably believed the professional relationship was still active.
A closing letter will not solve every later dispute. But the absence of a clear closing record can leave too much room for competing narratives. The firm may say the matter ended. The client may say they were never told. The later dispute then begins with an avoidable uncertainty about the basic status of the relationship.
The case-study concern
The concern raised in the source draft is that Burnetts Solicitors drafted a will in April 2022 which is said to have identified a business as a significant asset. It is then alleged that, in August 2023, the firm acted for the client’s landlord in a dispute said to affect that same business interest.
The draft also makes serious allegations about rent, forfeiture, lockout, eviction and enrichment. Those allegations are not treated here as findings. The publication-safe issue is narrower: where a firm has handled a will or estate-planning file involving sensitive asset information, what should happen before it later acts in a matter said to be adverse to the former client’s connected business interest?
That question does not require the reader to decide the disputed case. It asks whether the professional record should show the retainer status, closing communication, information held, conflict analysis, consent position, safeguards and decision to act.
What closing letters do
A closing letter is useful because it turns an implied ending into a documented ending. It can confirm that the agreed work is complete, explain any remaining steps, identify documents returned or retained, set out storage arrangements, remind the client about future review points, and make clear whether the firm is no longer acting.
That clarity protects both sides. The client receives a record of what has happened and what remains their responsibility. The firm has evidence that the retainer has ended and that any future work will require fresh instructions or a new scope. In estate-planning work, that can be particularly important because a will may remain legally and personally significant long after the drafting file is closed.
The practical point is not that every missing closing letter proves misconduct. It does not. The point is that a closing letter reduces avoidable ambiguity. In a later conflict dispute, the closing record may become part of the evidence that shows when the active instruction ended and what the client was told at the time.
Scope closure
Confirms what work has been completed and whether the firm is still acting.
Client protection
Explains outstanding steps, document handling, future review points and responsibility for next action.
Conflict record
Helps distinguish the end of active work from continuing confidentiality and former-client duties.
What closing letters do not do
A closing letter does not wipe the slate clean. It does not make confidential information available for use in later adverse work. It does not remove the need for a conflict check. It does not mean a firm can ignore material information obtained during the earlier retainer. It does not answer whether consent, safeguards or refusal to act were required.
That distinction is central. Retainer closure is a scope question. Former-client confidentiality is a professional-duty question. They overlap, but they are not the same.
In a will context, the distinction is especially important. The active task may be narrow: prepare and execute a will. The information disclosed may be much wider: business assets, family intentions, liabilities, succession concerns, property interests and personal priorities. Some of that information may later become material if another instruction touches the same business, property or asset.
Former-client confidentiality
The SRA framework already recognises that duties can survive the end of the retainer. Current and former client affairs must be kept confidential unless disclosure is required or permitted by law or the client consents. That duty is wider than simply avoiding the physical transfer of documents.
The harder question is materiality. What confidential information was actually held? Was it relevant to the later instruction? Did the later client have an interest adverse to the former client? Who within the firm had access to the earlier file? Were any effective measures in place to remove any real risk of disclosure? Was informed written consent required or obtained?
Those are not academic questions. They are the questions that separate a general grievance from a structured former-client conflict concern. A firm may ultimately be right that it could act. But the route to that decision should be capable of being reconstructed.
Information held
What confidential information was obtained through the earlier will or estate-planning retainer?
Later adversity
Was the later instruction adverse to the former client in a way that made the information material?
Protection route
Was there consent, an effective safeguard, a refusal to act or a recorded reason why no conflict arose?
The policy question
The source draft calls for mandatory closing letters and clearer former-client duty rules. The first proposal is easier to understand as a client-care reform: every client should be able to tell when the matter has ended, what the firm has done, what the client must do next, and whether the firm is continuing to act.
The second proposal needs more careful framing. A bright-line rule for all former-client duties may sound attractive, but former-client risk is often fact-specific. The better reform question may be whether the SRA and the profession should give clearer practical guidance for high-risk areas such as wills, trusts, estates, family businesses, commercial leases and connected asset disputes.
That would avoid two errors. It would avoid telling clients that their former solicitor’s duties end at the instant the file closes. It would also avoid telling firms that any historic will or estate file prevents all future work for another client. The better route is recorded judgement: scope, information, materiality, adversity, consent, safeguards and reasons.
Closure discipline. Clear end-of-matter communications as a routine client-care standard.
Risk categories. Practical guidance for wills, estate planning and connected business assets.
Record keeping. A documented reason why later adverse work was accepted, limited or refused.
Client confidence. Better transparency without overstating what a closed retainer can achieve.
The evidence route
A closing-letter complaint should be built from documents rather than assumption. The starting point is the retainer: client care letter, scope of work, will instructions, drafts, asset information, correspondence, bill, completion email, file-closing record and any document-retention note.
The next step is the later instruction: who was the new client, what was the dispute, what asset or business was affected, what information overlapped, what individuals or teams were involved, and what explanation did the firm give when challenged?
The final step is route selection. Is the issue missing client-care clarity, absence of a closing letter, former-client confidentiality, adverse acting, lack of consent, ineffective safeguards, professional negligence, data protection, complaint handling, SRA reporting, Legal Ombudsman complaint or civil claim? The more precise the category, the harder the concern is to dismiss as mere dissatisfaction.

Agreed work, next steps, what is included and what is outside scope.The Legal Lens point
Closing letters matter because they make the end of the active retainer visible. Former-client duties matter because some professional obligations survive that ending.
The two points should not be confused. A missing closing letter does not automatically prove a conflict. A closing letter does not automatically clear one. The real question is whether the professional route can be shown: what work ended, what information remained protected, what later instruction arose, what conflict check was done, what consent or safeguards were considered, and why the firm decided it could act.
Clients should not have to infer the end of their matter from silence. Firms should not have to defend later instructions without a clear record. The practical reform is simple: close the retainer clearly, preserve confidentiality rigorously, and record the conflict decision before the dispute begins.
