How to Write a Case Study for a Law Firm (Without Breaching Client Confidentiality)

07 August 2026·6 min read

Quick answer: Yes, you can write a compelling case study without naming a client or breaching confidentiality — de-identify the facts (dates, figures, location, identifying detail) while keeping the strategy and outcome intact. Get written consent for anything borderline, use a consistent Situation/Approach/Outcome structure, and change any detail combination that could let someone connect the dots. Some matters simply can't be safely published, no matter the effort. ✨

Most law firms sit on a goldmine of proof they never use. Every settled matter is evidence of what a prospective client wants to know before they call: can this firm actually do the thing? Yet the case studies page, if it exists, is usually three vague paragraphs about "achieving a favourable outcome" that could describe any matter, ever. We get it 💖 — confidentiality isn't optional, and legal advertising rules are strict. But "we can't share details" and "we can't write a case study" aren't the same thing. Here's how to do the second one properly.

What most law firms get wrong

Two failure modes, seen across every practice area. First, firms go so vague protecting confidentiality that the case study proves nothing — "a client came to us with a difficult matter and we achieved a great result" could be about literally anyone. Safe, and useless, because prospective clients can't see themselves in it. Second, less often but more dangerously, firms include just enough real detail — a suburb, a settlement figure, a distinctive fact pattern — that anyone who knew the matter could work out who it was. Neither serves the firm. The goal is a story specific enough to feel real, generic enough that the client themselves wouldn't recognise it.

Please note: general information, not legal advice — check your state law society's advertising rules and client confidentiality obligations before publishing any case study.

The copy-paste case study template

Steal this structure — it works across family law, commercial, criminal defence and most practice areas we've applied it to.

1. Situation (2–3 sentences)
The type of matter and the client's core problem, using a role rather than a name ("a small business owner"). State roughly what was at stake, no exact figures.

2. Approach (3–4 sentences)
The strategy, legal mechanism and judgement calls. This is where expertise actually shows — the hardest part to fake and the part clients are really evaluating.

3. Outcome (2–3 sentences)
The result in ranges or general terms ("settled well ahead of the court date"), never exact figures or dates, and never a guarantee of the same result for someone else.

4. De-identification checklist:

Exact dates ("in 2023," not a specific week)
Exact dollar figures (use ranges or relative terms)
Suburb, workplace, school or other location detail
Ages, family size, distinctive structure
Anything the client called "unusual" about their matter
Detail combinations that are identifying together, even if fine alone
Written consent on file, even when you think it's de-identified enough not to need it

Three worked examples

Family law firm — Halligan Family Law, Robina: A real property settlement involved a self-employed spouse who'd understated business income. Publishing the industry, figure or year risked identification in a small professional circle, so it became "a self-employed parent whose ex-partner's income was difficult to verify." The approach detailed the forensic accounting request and negotiation strategy; the outcome was "a settlement that fairly reflected the business's true value, reached without a final hearing." No industry, no figures, no suburb.

Commercial/conveyancing firm — Marsden & Cole, Southport: A lease dispute where a landlord tried to terminate a tenant over a technical breach during a hard trading period. Even the property type risked identifying the client locally, so it generalised to "a retail tenant facing termination over a disputed technical breach," focused the approach on the clause interpretation and negotiation leverage used, and gave the outcome as "the lease was preserved on amended terms" — no address, dates or rent figures.

Solo criminal defence practitioner — Renee Kavanagh, Nerang: Hardest category — charge type, court and timing can all be identifying, and clients are fairly sensitive about being linked to a criminal matter at all. A drink driving matter with mitigating circumstances became "a first-time traffic offence with strong mitigating circumstances," the approach covered the character evidence and early plea strategy in general terms, and the outcome was "avoided a recorded conviction." Consent was obtained before drafting, not after.

How the de-identification actually works

Separate the facts that make a matter legally interesting from the facts that make it identifiable, and publish only the first. A prospective client doesn't need the $1.4 million settlement in Mermaid Beach — they need to know you've handled settlements involving hidden business income, and can explain how. Change identifying combinations, not just single details; three innocuous facts together can identify someone as surely as one obvious one. Then ask: would the client recognise themselves? If yes, it's not de-identified enough, consent or no consent.

💡 Some matters can never be safely published, however much you de-identify. Unusually rare fact patterns or matters where the client is locally well known should stay off your website, full stop. When in doubt, ask the client directly — if they hesitate at all, that's your answer.

Mistakes to avoid

Publishing without written consent because it "feels" de-identified enough
Using real or rounded settlement figures in a small practice community
Writing the outcome as a guarantee or implied promise for future clients
Going so vague the case study could describe any matter — it needs to feel specific to be believable
Framing a client's worst day as a marketing win without acknowledging the human cost
Reusing the same template details so every case study sounds identical

Frequently asked questions

Do I always need written client consent, even for a de-identified case study?

Yes, as good practice and often a professional obligation under your state law society's rules. Even a well de-identified matter can occasionally be recognised by someone with inside knowledge, so consent is the client agreeing their story can be told, not a formality.

Can I use exact settlement figures if I round them?

Generally, no. Rounding to the nearest hundred thousand can still tell a small circle of people — former colleagues, opposing counsel, the client's own family — roughly which matter it was, especially with a suburb or timeframe attached. Use ranges instead.

What if a case study isn't punchy without a few identifying details?

Sometimes that's true, and the right call is to let that matter go rather than compromise confidentiality for a better sentence. The strategy and judgement calls are usually the interesting part anyway, not the numbers.

Is it ever okay to combine two real matters into one case study?

Yes — a composite built from two or three similar matters can protect confidentiality better than a single de-identified one, provided you don't present it as one client's experience. Be transparent internally, and check your local rules on how composites should be described.
