Most partners who consider lateral moves think about it too late. Here's how to evaluate whether a move is right for you — and how to tell the difference between a real opportunity and a distraction.
The question of whether to make a lateral move is one of the most consequential decisions in any partner's career. And it's often approached with far less rigor than partners bring to their most routine client matters.
Part of this is structural. Most partners who explore a move do so reactively — prompted by a recruiting call, a deteriorating internal situation, or a serendipitous conversation at a conference. Few approach it the way any sophisticated transaction would be analyzed: with a clear-eyed view of the relevant economics, the risks on both sides, and a well-defined sense of what success actually looks like.
The fundamental question
Before any specific opportunity is evaluated, a more foundational question deserves honest attention: Is my current situation limiting what I can build?
There are many legitimate versions of this constraint. Your firm's platform may be insufficient for the clients you're trying to serve — lacking the geographic reach, practice depth, or institutional relationships necessary to grow your practice the way you envision. Your compensation structure may not reflect the value you're generating, either because of systemic firm economics or because of how your particular group is valued internally. Your internal relationships may have eroded to a point where you're functionally operating as a sole practitioner inside a large firm. Or your firm's direction may have simply diverged from your own.
If none of these conditions are present — if your platform is strong, your economics are fair, and your internal position is secure — then a lateral move may be a solution to a problem that doesn't exist. But if any of these conditions are meaningfully in play, staying has a cost, even if that cost is less visible than the disruption of leaving.
The economics of portability
Portable business is the currency of partner lateral moves, and it's more nuanced than most firms (and most partners) acknowledge. The book that travels is not simply the total revenue associated with a partner's clients — it's the subset of that revenue that is genuinely relationship-based, that isn't dependent on institutional infrastructure, and that can realistically continue through a transition.
Sophisticated firms doing due diligence on a lateral candidate are asking a version of these questions: Which clients are truly yours? How long have those relationships been personal versus institutional? What is the tenure and relationship depth with each significant client? Would the work follow you if the firm changed, or would it follow the firm even if you left?
Partners who overestimate portability set up difficult transitions. Those who understand it precisely — including its dependencies and vulnerabilities — can structure conversations with prospective firms realistically and build the right expectations on both sides.
Timing
There is a common pattern in lateral partner moves where the decision to move comes roughly two to three years later than the moment when the constraint became apparent. Partners are patient. They give their situation time to improve. They wait for a specific partner to be promoted, for a management change to take effect, for a promised investment to materialize. Sometimes these bets pay off. Often they don't, and the delay means arriving at a new firm with a book that has stagnated rather than grown.
The best time to explore a lateral move is not when you're unhappy — it's when your practice is strong, your relationships are active, and you have genuine leverage. That's when you can negotiate the best economics, the most supportive transition structure, and the firmest commitments about investment in your group. Waiting until your situation is bad reduces your leverage precisely when you need it most.
What a real opportunity looks like
Not every recruiting call represents a meaningful opportunity. The partner calls worth taking seriously share a few characteristics: the firm has a genuine strategic need in your practice area (not just a desire to add revenue); the platform offers something your current firm can't provide; the economics are structured to be fair through the transition period, not just on paper; and the specific partners you'd work most closely with are people you'd actually want to work with.
The calls worth declining are those where the offer is primarily financial — a larger draw or guarantee with no substantive difference in platform — and where the fit is unclear. Money is important. It's rarely the best reason to make a major professional transition.
