An Australian law firm’s goodwill is typically worth between 0.5x and 1.5x annual gross fees — or roughly one-third of gross fees as a quick back-of-envelope check for sole practitioners. Total sale price, including work in progress and debtors, often lands between 1x and 2.5x annual net profit. That range is wide because practice type, location, and how much of the firm’s revenue actually sits with you personally — rather than with the firm — move the number significantly. If you’re starting to think about what your practice might fetch, this is how the valuation actually gets made.
How Australian Law Firms Are Valued
Two components make up the sale price: goodwill and the balance sheet (work in progress, debtors, plant and equipment).
Goodwill is the main event. It represents the value of the client base, the firm’s reputation, and the recurring revenue stream — detached from the physical assets. For most boutique and mid-size Australian law firms, goodwill is calculated as a multiple of annual gross fees. The range runs from 0.5x for a practice with high personal dependency and a single principal, up to 1.5x for a well-staffed commercial firm with institutional clients and documented systems.
The “rule of one-third” is the traditional shortcut: take one-third of annual gross fees as a goodwill proxy. It’s a starting point, not a conclusion — it ignores margins, staff structure, and client transferability entirely (which is doing a lot of the work). Treat it as a sanity check rather than a sale price.
The quotable rule of thumb: a law firm billing $2M in annual fees might reasonably expect $800K–$1.5M in goodwill. Where in that range depends entirely on whether that revenue transfers with you or without you.
For a cross-check, look at net profit. A firm producing $450K in annual net profit — after a normalised owner salary — would typically sell for $1.1M–$1.8M in total. The multiple compresses at the lower end if key person risk is high; it expands at the upper end if the business is genuinely independent of the founder.

Why Practice Type Changes Everything
Not all legal work is equally transferable, and buyers price that directly.
Commercial and property law — particularly transactional work for business clients and developers — tends to attract higher multiples. The client is often a business or institution, the relationship has a degree of structural transferability, and the work repeats. A buyer acquiring a commercial property practice can reasonably expect that when a client’s next transaction arrives, they’ll call the firm, not necessarily you personally.
Family law and criminal law sit at the other end. Clients in those areas retained you specifically — your manner, your judgment, your relationship. When you leave, the revenue is vulnerable. Buyers know this and price it conservatively. It’s not a comment on the quality of the work; it’s the reality of what transfers and what doesn’t.
Conveyancing occupies the middle. It’s transactional, which is good. But it’s also commoditised and price-sensitive, which compresses margins and makes it harder to argue for premium multiples.
Rule of thumb by practice type:
- Commercial and property law: 1x–1.5x gross fees
- General practice: 0.6x–1.1x gross fees
- Family and criminal law: 0.4x–0.8x gross fees
- Conveyancing: 0.5x–0.9x gross fees
Location: CBD, Suburban, Regional
A CBD law firm and a suburban or regional practice have very different goodwill dynamics — and treating them identically is a mistake.
In a CBD practice, clients are typically corporate or institutional. The relationship with the firm is embedded in procurement processes, conflict checks, and file management. Business goodwill dominates. It transfers more predictably, and buyers factor that into the multiple.
A suburban or regional practice looks different. Clients often came because of you — word of mouth, a long-standing community connection, a referral from an accountant or financial planner who knows you personally. That’s personal goodwill, and it sits with you rather than the firm. When you sell, a portion of it leaves regardless of your intentions. Buyers build that risk into the offer through a lower multiple or an earn-out where part of the purchase price is contingent on client retention.
Regional practices in Western Australia — particularly in the Pilbara, South West, and Goldfields — can attract motivated buyers specifically because there’s limited competition for the client base. The scarcity premium can offset some of the personal goodwill discount, but don’t rely on it. A regional scarcity advantage and a personal goodwill risk can cancel each other out in a buyer’s model faster than you’d expect.
Personal Goodwill vs Business Goodwill
This is the most important concept in law firm valuation, and the one most sellers underestimate.
Personal goodwill sits with you. It’s the value attributable to your reputation, relationships, and judgment that won’t automatically transfer to a buyer. Business goodwill belongs to the firm — the brand, documented systems, recurring institutional client relationships, and staff who have their own direct client contact.
In a buyer’s mind: personal goodwill is risk. Business goodwill is value.
If your firm’s revenue would decline materially on day one without you, you have significant personal goodwill — and a buyer will either price that risk in, or ask you to remain under an earn-out or employment arrangement for two to three years. Neither is necessarily a bad outcome, but you need to understand the mechanics before you agree to terms.
I spoke with a broker last year about the sale of a regional WA practice — profitable, well-run, nearly three decades old. The principal had agreed to a two-year handover. But the introductions to the incoming buyer were rushed and the client communication plan was light. Client retention in the first twelve months post-settlement was around 60%. The earn-out that had looked like a minor formality ended up costing the seller $180K in contingent payments that simply didn’t materialise. The lesson isn’t to work harder at handover. It’s to understand what you’re actually selling, and negotiate deal terms accordingly, before you sign the heads of agreement.
The goodwill valuation guide covers the personal vs business distinction in more depth across different professional services.
What Happens to Your WIP and Debtors
Work in progress and trade debtors are separate from goodwill — but how they’re handled in the deal structure significantly affects what you actually receive at settlement.
Work in progress is unbilled time and disbursements at the date of sale. In most law firm transactions, WIP is either excluded from the sale price entirely (the buyer takes it as part of the handover for no additional payment) or included at 85–95 cents in the dollar for billed WIP. Unbilled WIP — particularly time that may not translate to a billable invoice — gets a steeper discount or is simply left with the seller to manage out.
What you don’t want is to reach settlement without an explicit WIP agreement. It’s one of the most common sources of dispute after law firm sales, and it’s entirely avoidable with clear heads of agreement.
Debtors (outstanding invoices) are typically included at a haircut of 10–15% to account for collection risk. Some buyers prefer to exclude debtors entirely and let you collect them post-settlement, which can work well if your ledger is clean and aged receivables are minimal.
The total package — goodwill plus WIP plus net debtors plus plant less liabilities — is your actual gross proceeds. A firm with $1.5M in goodwill, $180K in clean WIP, and $120K in recent debtors could realistically realise $1.7M–$1.9M at settlement. Work through that arithmetic before you set expectations.
How to Increase Your Firm’s Value Before You Sell
If you’re planning to sell in two to four years, specific structural moves lift the multiple — not cosmetically, but in ways that change how a buyer’s risk model prices your firm.
Reduce your client concentration. If your top five clients represent more than 35% of fees, buyers will either discount the multiple or build in contingent payment terms. Start introducing senior staff to those clients now. Transition file management. Make yourself replaceable on day-to-day matters even if you remain the lead relationship contact.
Document your systems. File management, onboarding, billing, conflict checks, supervision — write it down. A buyer in due diligence wants to see a firm that runs on documented procedures. A firm that runs on the principal’s memory is a client book sale; a firm that runs on systems is a business sale. The multiple difference between those two descriptions is real.
Extend your recurring retainer base. Businesses on annual retainers, developers with standing relationships, corporates on fixed-fee arrangements — formalise those relationships before going to market. Recurring revenue under a signed retainer is an asset on the information memorandum. Revenue that recurs by habit is just a hope the new owner inherits.
Run a clean P&L for three years. Normalise owner salary, remove personal expenses beyond what’s genuinely defensible, and make sure your EBIT holds up without a long list of add-backs. Every add-back you need to explain creates friction with a buyer — and friction compresses multiples.

Tax on Selling Your Law Firm
The structure of your practice and the deal type — share sale versus asset sale — determines how much of the gross proceeds you keep.
A share sale in a company produces a capital gain on your shares. Held for more than twelve months, the 50% CGT discount applies. The small business CGT concessions can reduce the taxable gain further, potentially to zero for principals over 55 who are genuinely retiring from the business. This is usually the most tax-efficient outcome and why most sellers prefer it.
An asset sale produces a more complex position: goodwill is a capital gain, WIP and unbilled work may be assessed as ordinary income, and plant and equipment can trigger depreciation recapture. Asset sales are common where the buyer wants a clean start without inheriting the entity’s history — they’re not necessarily worse deals, but they need specialist tax advice well before heads of agreement, not as an afterthought once you’ve agreed on price.
