The Best Law Firm Expansion Is the One You Walk Away From

By Stijn van Oirschot ยท

Geographic and lateral growth succeed on culture and client logic, not opportunity. Every expansion has to pass two tests at once, and the emotionally obvious move often fails them.

When a law firm thinks about growth, the conversation usually turns to the map. A new city, a new office, an acquisition that doubles headcount overnight. These moves feel like progress because they are visible. They are also where a great deal of value quietly goes to die.

The firms that expand well have learned an uncomfortable lesson. The best expansion decision is often the one you walk away from, and the discipline to walk away is what separates intentional growth from expensive opportunism.

Expansion is an investment, and most firms forget the second half of that sentence

Venturing into a new market is an investment, which means it takes time to pay off even when you get it right. Firms accept this in principle and forget it in practice. They expect a new office to contribute quickly, lose patience when it does not, and conclude the strategy was wrong, when the only thing wrong was the timeline. Treating expansion as an investment changes the questions you ask before you commit, and the patience you bring afterwards.

The two questions every expansion must pass

A sound expansion has to clear two tests at the same time, and clearing only one is how firms talk themselves into bad moves. The first test is client demand: is there genuine, long-term client need in this market, or merely the excitement of a new flag on the map? The second is cultural portability: can the firm carry its own identity and way of working into the new market, or will distance and local difference produce a firm within a firm?

A market can pass the demand test and fail the culture test, and that combination is more dangerous than no expansion at all, because it grows the firm's name while diluting the thing the name stood for.

Why the obvious move is often the wrong one

The most instructive expansion decisions are the ones firms decline. Consider the pull of an established legal centre, the city that already sends the firm most of its instructions. Opening there looks inevitable. Yet the better question is the direction of travel: where are clients heading over the next decade, not where did yesterday's work originate? A firm that follows clients toward where demand is growing, rather than planting a flag where demand already peaked, makes a harder choice and usually a wiser one.

The same discipline applies to acquisitions. Buying a local firm to enter a market looks efficient, but if the firm's value rests on a distinctive identity and a particular kind of work, a local acquisition can import revenue while exporting the culture. Sometimes the right structure is a small, deliberate presence that acts as a bridgehead for cross-border work, not a full local capability bolted on by purchase.

Culture, not data, underwrites growth

Firms reach for data to justify expansion, and data has its place. But the thing that actually underwrites growth across borders and generations is culture. A firm grows by hiring local experts and combining them with people who already carry the firm's identity, so that the new office inherits the firm's way of working rather than inventing its own. The role of senior partners shifts in the process. They become custodians of culture, responsible for passing the firm's identity to each new generation and each new market.

This is slow, unglamorous work, and it is the difference between a firm that expands and a federation of offices that happen to share a logo. (It is the same cultural work that decides whether a lateral hire integrates or sits apart, which we explore in partner alignment.)

Grow the pie, do not slice it

Expansion and lateral growth live or die on compensation, because compensation is where a firm's real values are revealed. A model that rewards individual hoarding teaches partners to protect their own numbers, which is fatal to collaboration across offices and practice areas. A model built around growing the whole pie, rewarding collaboration and the long-term, intangible contributions that do not show up in a single year's billing, teaches the opposite.

This is also the truest test of a lateral partner's fit. If the driving question a candidate asks is always what is in it for me, that is useful information: it may simply be the wrong firm for them to join. The partners who strengthen a firm are the ones who think in terms of the pie, not the slice.

These are commercial decisions partners were never trained to make

Deciding whether a market will pay off, how to structure an entry, and how to design compensation that rewards the right behaviour are some of the hardest commercial judgements a partnership faces. They are also judgements lawyers are rarely equipped to make, because the path to partnership rewards legal excellence, not investment appraisal.

That gap is exactly what The Law Firm Growth Game is built to close. When partners spend a day running a firm, weighing an expansion against the cash it consumes and the patience it demands, the abstract becomes concrete. A partnership that has felt an over-ambitious expansion drain a simulated firm brings far more rigour to the real decision.

Discipline is the strategy

Growth is not the same as expansion, and the firms that understand the difference grow more reliably than the ones chasing the map. They commit only when demand and culture both hold, they follow clients rather than nostalgia, and they reward the partners who grow the pie. Often the most valuable decision they make is the expansion they choose not to pursue.

Common questions

How should a law firm decide whether to enter a new market?

An expansion should pass two tests at once: genuine long-term client demand in the market, and the firm's ability to carry its culture and way of working into it. Passing only one of the two is a warning sign, not a green light.

Is acquiring a local firm a good way to expand?

Not always. If a firm's value rests on a distinctive identity and a particular kind of work, a local acquisition can bring in revenue while diluting the culture. Sometimes a small, deliberate presence that bridges cross-border work serves the firm better.

Why does culture matter more than data in law firm expansion?

Because data can justify a move that culture cannot sustain. Firms that expand well combine local experts with people who already carry the firm's identity, and rely on senior partners as custodians of that culture across new offices and generations.

What is the best partner compensation model for growth?

One that rewards growing the whole pie rather than slicing it: recognising collaboration and long-term, intangible contributions instead of individual hoarding. Compensation reveals a firm's real values and shapes whether partners work together across offices.

How can you tell if a lateral partner is a cultural fit?

Listen to the driving question. If a candidate's overriding concern is always what is in it for me, the firm may be the wrong home for them. Partners who strengthen a firm think in terms of the collective pie, not their personal slice.
