​Every law firm has one, and often several: the senior partner whose name clients ask for, whose relationships underwrite a meaningful slice of the firm's revenue, and whose eventual departure everyone knows is coming but no one quite wants to plan for. The rainmaker is the person the firm was, in some sense, built around. And the transition of their practice to the next generation is, in our experience, one of the hardest things a firm ever has to do well.

At Carlyle Kingswood Global, we work with firm leaders across Australia, Asia and the UK who are grappling with exactly this question, usually later than they should be. Succession is rarely handled badly because anyone is incompetent. It is handled badly because it is uncomfortable, because it is easy to defer, and because the very success of the rainmaker disguises how fragile the arrangement really is.

The problem hides in plain sight

A firm with a dominant rainmaker often looks, from the outside, like a firm that is thriving. The revenue is there. The clients are loyal. The partner is energetic and shows no sign of slowing. Everything is fine — until the day it is not.

The trouble is that client relationships built over decades tend to be intensely personal. The client does not instruct "the firm"; they instruct a person they trust, whose judgement they have relied on through their own career. When that person retires, the loyalty does not automatically transfer to whoever inherits the file. It has to be rebuilt, and it has to be rebuilt in advance, because a relationship cannot be handed over in the final six months before a partner walks out the door.

This is why succession that begins as a retirement conversation has almost always begun too late. By the time a rainmaker is ready to discuss winding down, the window in which their relationships could have been transitioned gracefully has usually closed.

Why firms defer it

If the risk is so obvious, why is it so consistently ignored? A few reasons recur.

The first is that the rainmaker themselves is often ambivalent. Their identity, status and sense of purpose are bound up in being the person clients call. Actively training and involving a successor can feel like an admission that the end is near, and it can feel like giving away the very thing that makes them valuable to the firm. Even the most generous senior partner can find succession quietly threatening.

The second is that firms are structurally short-termist about it. Transitioning a client relationship means, in the near term, introducing a more junior partner into meetings, sharing credit, and sometimes accepting a slightly less polished client experience while the successor finds their feet. All of that has a cost today in exchange for a benefit that only materialises years later. Firms that are managed quarter to quarter rarely make that trade willingly.

The third is simply that it is awkward. Succession forces conversations about mortality, money, and control that most partnerships would rather not have over a Tuesday lunch. So they are deferred, politely and indefinitely, until an illness or a sudden decision forces the issue on the worst possible timeline.

What good succession actually looks like

The firms that manage this well share a pattern, and it is worth describing plainly.

They start early — years, not months, before the anticipated transition. They treat succession as a normal part of managing a practice rather than an emergency to be handled at the end.

They introduce the successor into the relationship long before it matters, so that the client comes to know and trust two people rather than one. The best transitions are so gradual that the client barely notices the handover has happened; the second name has simply become as familiar as the first.

They align the incentives honestly. If a rainmaker is asked to give away relationships they spent thirty years building, the firm has to make it worth their while to do so — through the way retirement and equity are structured, through recognition, and through a genuine role in the transition rather than a cliff edge. A succession plan that asks a senior partner to surrender their life's work for nothing is a plan that will quietly fail.

And they are realistic about who the successor should be. The instinct is often to hand the practice to the most technically brilliant lawyer in the team. But inheriting a relationship-driven practice is not primarily a technical challenge; it is a relationship challenge. The successor needs the client-handling instincts, the presence, and the commercial judgement to hold a relationship that was built on exactly those qualities. Sometimes that is the obvious heir. Sometimes it is not.

Succession as a growth question, not a defensive one

It is tempting to frame all of this defensively — as risk management, as protecting revenue against the day a partner leaves. That framing is not wrong, but it is incomplete.

Handled well, succession is one of the most powerful growth levers a firm has. It is how a practice outlives the individual who created it. It is how the next generation is given the responsibility and the client exposure that turns capable senior associates into genuine partners. And it is how a firm signals to its most ambitious people that there is a real future for them here — that the top of the firm is not permanently occupied by people who will never move aside.

A firm that transitions its rainmakers well is a firm that keeps its rising talent, because those people can see a path. A firm that never does is one where the most driven lawyers eventually conclude that the only way up is out — and often, they leave to build their own practices elsewhere, taking the firm's future with them.

The point

The retiring rainmaker is not a problem to be managed at the end of a career. It is a question every firm should be answering continuously, quietly, as a matter of ordinary good management. The relationships that took decades to build cannot be transferred in a hurry, and the firms that understand this begin the work long before anyone is thinking about retirement.

At Carlyle Kingswood Global, much of our work with firm leaders is about exactly this: building the bench, identifying and developing the people who can carry a practice forward, and helping firms make the transition before circumstance makes it for them. The firms that do it well are not the ones with the best individual rainmakers. They are the ones that never had to depend on any single person for very long.
