Thought Leadership: A Third of Lateral Partners Leave within 5 Years. Here’s why
Here's a number that should make every managing partner uncomfortable: roughly 30–38% of lateral partner hires leave their new firm within five years. And 90% of firms report "business development challenges" with their lateral hires.
A new report from Passle — surveying 100 managing partners and BD leads at the top 200 US and top 100 UK firms — puts data behind what many of us in the recruiting world have observed for years. Firms are pouring resources into lateral recruitment while systematically underinvesting in lateral integration. The result is a staggeringly expensive revolving door.
The report cites Decipher Investigative Intelligence research noting that a failed lateral hire can cost a firm 200–400% of that lawyer's annual compensation once you factor in recruiter fees, guarantees, transition costs and replacement expenses. And … 100% of surveyed firms report struggling to transfer the book of business from an incoming lateral.
One hundred percent.
Here's what I think firms get wrong: they approach lateral hiring as a book-acquisition exercise rather than a platform-integration exercise. They're not wrong to care about the book, that's the business rationale for the hire. But if the relationship with the new firm is implicitly framed as "we want your clients and we'll tolerate you in the meantime," the lateral will feel it and they'll leave.
The firms most satisfied with their lateral outcomes, according to Passle's findings, share one characteristic: they identify "engagement in internal and external networking" — not revenue brought in — as the leading indicator of lateral success. The fastest-growing firms understand that trusted relationships and genuine integration come first; sustainable revenue follows.
Having spent years on both sides of this equation — as a practicing attorney and now as a recruiter at Strategic Search Resources — I can tell you the laterals who thrive are the ones who arrive at a firm that actively helps them succeed, not just ones who check a box in the hiring committee's revenue projections.
Partners evaluating a move: ask the hard questions about integration before you sign. Ask specifically: how does the firm measure lateral success in year two and year three; not year one? The answer will tell you everything.
