The financial afterlife of a matter
Firms move, merge and change shape more easily now. The duties attached to finished work still need a lasting home, and a way to pay for it.
Picture an eight-lawyer firm. It gives up its lease and moves to a distributed way of working. Live matters carry on smoothly. Three years later, a former client asks for an old file. The partner who ran the matter has left. The paper file went into storage when the office closed, and the digital copy sits on a drive nobody’s checked. The office savings were real. So is the cost of piecing the past back together.
A matter’s financial afterlife starts when its revenue stops. Storing, securing, finding, moving and finally disposing of the file can all cost money long after the final invoice. A firm that wants to work more flexibly needs to know what it’s still committed to before it can judge what a change will really save.

Illustrative, based on the hypothetical firm above. Hatched band: storage, security and access controls run throughout. Timings vary by matter and jurisdiction.
Usable for years, not just today
Working from anywhere and keeping records usable for years are different things. The first lets a lawyer work from home or another office. The second means the practice can still find and produce a file after its people, offices and structure have changed. A file that opens on a laptop today has passed the first test. That says little about whether someone else can produce it in five years.
The National Archives of Australia puts the timing problem plainly: “Many records have retention periods longer than the life of the systems they are captured in.” Its digital preservation guidance names three kinds of obsolescence: file format, software and hardware. These are principles for government records, not rules for private firms. But the lesson travels: paying for storage doesn’t guarantee a file will still be usable.1
For a practice manager, the test is easy to state. Can authorised people find, understand and produce the records the firm has kept? Depending on the matter, that can mean emails, attachments, metadata and financial records as well as readable documents.
The Law Society of NSW’s October 2025 guidelines match the format to the job. They suggest “PDF or PDF/A for court submissions and finalised documents”, DOCX for drafts and XLSX or CSV for structured data. Information should be searchable. To preserve metadata, they suggest keeping electronic documents, including emails, in their original or native format. They also suggest agreements with cloud-based practice management providers so information can be retrieved, searched or transferred on retirement, death or sale.2
Native files and PDF/A do different jobs. A native file, such as a Word document or an Outlook email, is made for working. It relies on compatible software and stays editable. Its metadata can change when it’s edited, copied or migrated. PDF/A, defined by ISO 19005, is made for keeping. The Library of Congress describes its purpose as preserving a document’s “static visual appearance over time, independent of the tools and systems used”. Its fonts are embedded, encryption isn’t allowed and basic descriptive metadata must be stored in XMP.3 The Library lists PDF/A among its preferred formats for digital text, and Word formats as acceptable.4 For finished documents, that makes PDF/A the stronger keeping format, provided the metadata comes with it.
Wills and deeds are different
The Law Society of NSW’s guidelines make an exception for safe custody documents, including wills and deeds. They “should not be digitised or destroyed” and “must be retained in their original form”. A central safe custody register should be kept securely and separately from the documents. A firm can give up its office without giving up responsibility for a will or deed, and digital convenience can’t replace that arrangement.2
When a practice closes
Closing a practice makes the responsibility hard to miss. In NSW, the Law Society’s guidance puts responsibility for a closed practice’s archived files on its former principals. That includes an incorporated legal practice in liquidation: managers or liquidators don’t take on designated responsibility for its archived files. A change to the entity doesn’t settle the professional responsibility.5
The Queensland Law Society’s Practice Advisory Service team puts it plainly in Proctor: “Closing your practice does not absolve you of discharging your professional obligations.” So retirement plans and sale negotiations should name who’ll look after the archive, what the work involves and how it’ll be paid for. The files aren’t a minor handover detail.6
What has to be kept, and for how long
Keeping everything forever is an expensive way to avoid deciding what’s needed. Under rule 14.2 of the Australian Solicitors’ Conduct Rules, as applied in NSW, a solicitor may destroy client documents seven years after the engagement is completed or terminated. Client instructions or legislation can say otherwise. It’s a permission, not an instruction, and it doesn’t apply to safe custody documents.5
Where the Privacy Act applies, there’s a second duty. APP 11.2 requires reasonable steps to destroy or de-identify personal information once it’s no longer needed for any purpose for which it may be used or disclosed under the APPs. The exceptions include information that an Australian law, or a court or tribunal order, requires to be kept.7
Make the remaining cost visible
The financial answer is to make the remaining cost visible. An internal estimate can add up storage and custody, staff time spent on retrieval, access controls, expected moves and disposal. Keep the regular costs separate from occasional ones, such as a move. The estimate helps with decisions about pricing, profitability and what a change will really cost. How to account for it formally is a separate question.
Grouping finished matters by year and type makes the estimate manageable. Start with one group: how long its files must still be kept, how often they’re retrieved and what suppliers actually charge. Then refine the numbers as evidence builds. Some matters may turn out less profitable than they looked, because their future administration was never counted.
A firm that expects to change offices, people or structure more than once needs continuity built in. A merger, a partner leaving, an office move or a retirement should trigger an agreed process, with known costs and owners. Agility is worth more when yesterday’s work can come along without being rebuilt each time. A matter is only economically complete when the firm knows what’s left to do.
Implications for practice managers
- Price the remaining work. Estimate what finished matters still cost, group by group, using real costs and retrieval numbers.
- Test retrieval. Ask for a typical closed matter from five years ago, then time how long it takes to find, open and produce in full.
- Plan for continuity. Write down who’ll control, retrieve and eventually dispose of kept files through a departure, sale, incapacity or closure, and how that work will be paid for.
