Volume mismatch
Partners whose books require four to six concurrent staffed matters cannot run the practice with a bench of two or three associates, regardless of quality.

Solo or Team? How Partners Move Firms
In our interviews with 2,600+ partners, team-move dynamics surfaced in over a third of all conversations. Corporate and disputes partners almost never move without asking about associate depth. A partner with a material book who cannot staff the work from day one is exposed immediately — so the question of whether to bring associates, and whether the destination firm can support the practice, is not a secondary consideration. It is the primary diligence question, and in roughly one in eleven conversations it becomes a potential dealbreaker objection.

Counts are of the ~940 team-move discussions in our corpus. The number moves with the practice because execution intensity does — not because some lawyers are more collegial than others. The full ranking is below.
What our interview data establishes.
Five findings drawn from Sartori Global's proprietary corpus of approximately 2,667 partner-level conversations. No individual or firm is attributable to any figure.
Personal bookInstitutional book
- Move solo A portable, personal book that follows the partner. The infrastructure conversation is secondary to the deal terms.
- Move with a team The largest cohort. The book needs personal transfer and firm-level support to survive and grow after the move.
- May not move at all Work bound to the firm — panels, standing instructions, fund relationships. The partner needs firm-level commitments or the move does not work.
These five findings frame the rest of this analysis. Read in order, they move from how often the team question is raised, to what is asked, to when it becomes a dealbreaker, to why portability sits underneath all of it.

How often does team-move come up in partner conversations?
Team-move dynamics surface in over a third of all partner conversations in our data. The distribution across practices is not uniform — and the skew tells you something important about where execution infrastructure matters most.
In our interviews with 2,600+ partners, team-move dynamics surfaced in approximately 35% of all conversations — around 940 discussions. That is a high baseline: team composition came up spontaneously in conversations across every tier and geography, from Magic Circle partners in London to boutique-platform partners in New York.
The 35% figure almost certainly understates the true frequency. Partners engaged in early-stage exploratory conversations often save detailed team diligence for later, once they have assessed the strategic fit of the target firm. What surfaces in the first or second interview is the threshold question: can the firm support me? If the answer looks doubtful, the conversation ends there. If it looks plausible, the partner returns with the specific team-composition questions catalogued below.
Which practices generate the most team-move discussions?
The distribution by practice is striking. Corporate/M&A accounts for roughly 22% of all team-move discussions — around 206 conversations — more than 60% larger than Disputes/Litigation in second place. The full ranking across our data is below.
The same ranking, sortable — click a column header to re-rank by count or share.
| Practice area | Discussions (approx.) | Share of team-move pool |
|---|---|---|
| Corporate / M&A | 206 | ~22% |
| Disputes / Litigation | 128 | ~14% |
| IP | 82 | ~9% |
| Banking & Finance | 78 | ~8% |
| Capital Markets | 48 | ~5% |
| Private Equity | 42 | ~4% |
| Projects / Energy / Infrastructure | 35 | ~4% |
| Real Estate | 32 | ~3% |
| Technology / Data | 31 | ~3% |
The concentration in Corporate/M&A reflects a structural reality of that practice: large-matter work is a team sport. A corporate partner at an international firm handling mid-market and upper mid-market M&A typically runs transactions involving multiple associates, often at different seniority levels, plus specialist sub-team input from tax, employment, and financing partners. That kind of origination model is not solo-portable. It transfers only if the destination firm can staff the work from day one, or if the partner can credibly move part of the associate bench.
Disputes/Litigation at ~128 discussions reflects a different dynamic. Trial-ready litigation partners often have associate dependencies built over years — juniors trained on specific client preferences, procedural styles, or specialist matters. Some disputes books are highly portable (the relationship follows the partner), but others are institutionally anchored to a firm-wide practice where associate and counsel depth is integral to the client value proposition.
That kind of origination model is not solo-portable.
What do partners ask about bench depth and headcount?
Across our interview dataset, questions about team size and office composition were the third most common question archetype. The specifics reveal what partners are actually trying to assess — not curiosity, but execution risk.
In our interviews with 1,000+ partners who asked substantive diligence questions, questions about team size, headcount, and office composition were the third most frequently classified archetype — approximately 9.6% of classified question discussions (116 discussions out of roughly 1,207 classified). They were outranked only by firm strategy/growth intent and compensation, two questions partners typically ask before anything else.
Where the bench question sits in partners’ diligence order — the top three question archetypes, most-asked first.
- 01Firm strategy & growth intentAsked before anything else — is this firm going somewhere?
- 02CompensationThe number, the guarantee, the model.
- 03Team size, headcount & office composition~9.6% of classified question discussions — the execution-risk question.
The distribution of this question archetype across practices is notably even. Across our data, the top practices are Disputes/Litigation, Corporate/M&A, and Banking & Finance — each accounting for roughly 13% of bench-and-headcount question discussions — with Technology/Data at approximately 9%. The evenness matters: it means that even practices where partners typically move with personal books rather than execution teams are asking about office composition. A technology/data partner at a mid-sized international firm asking how many associates the target office has is not planning to bring a team — they are assessing whether the platform can credibly service the work they generate.
What specific questions do partners actually ask about team composition?
The questions in our interview data cluster around four operational concerns. Each is a proxy for a different aspect of execution risk:
| Question pattern | Underlying concern |
|---|---|
| How many equity partners vs. counsel are in the practice, and in this office specifically? | Seniority skew — too many partners vs. juniors signals franchise-team imbalance; execution falls to the new hire |
| Would the incoming partner be the only practitioner in the office, or is there an established team? | Isolation risk — a solo partner with no associate bench is effectively building from scratch regardless of what the firm promises |
| What is the split of the associate bench between junior, mid-level, and senior associates? | Staffing quality — a bench heavy with very junior or very senior associates may not match the work profile the partner intends to bring |
| How many partners does the firm have in this practice across key offices, and what is the cross-office referral dynamic? | Network depth — a partner whose book involves multi-office or cross-border matters needs to trust that internal referrals will materialise |
The question that surfaces most acutely in our data is the equity-partner-to-associate ratio. Partners arriving at a firm where the practice has 14 partners and 3 associates — a real pattern from our exemplars — immediately recognise that execution capacity is constrained. Every major matter will compete for the same thin associate pool. The partner who brought the work will end up servicing it personally or, more dangerously, relying on associates borrowed from practices with different cadences and client relationships. That is an execution quality risk, not just a capacity issue.
Franchise-team imbalance, structurally — a top-heavy office where partners outnumber the associate bench leaves execution falling onto the new hire. Shape is illustrative; the 14-partner / 3-associate exemplar pattern is cited above.

Why the associate bench gap ends conversations.
The Associate Bench & Practice Infrastructure Gap is the fourth most common dealbreaker objection in our interview data — and unlike compensation or geography, it cannot be resolved by adjusting a number.
In our interviews with 2,600+ partners, the Associate Bench & Practice Infrastructure Gap objection was classified in approximately 9% of all classified objection discussions — around 252 occurrences out of roughly 2,789 classified. It ranks fourth in the overall objection frequency table, behind passive contentment, platform/brand downgrade, and culture mismatch. But among objections that are genuinely non-negotiable, it is arguably the most structurally intractable.
Why the bench gap is harder than the objections ranked above it — the others move with a lever the firm already controls; this one needs a real operational commitment.
- Compensation gapIncrease the guaranteea number moves
- Geographic objectionRemote or hybrid arrangementa policy moves
- Culture mismatchShifts as the partner learns moretime moves it
- Bench-gap objectionHire now, commit a hiring timeline, or accept a lower-revenue rampan operation must move
Compensation objections can be resolved by increasing a guarantee. Geographic objections can sometimes be resolved by remote or hybrid arrangements. Culture objections may shift as a partner learns more about the firm. The bench gap objection requires a material operational commitment: the firm needs to either hire immediately, guarantee a timeline for associate investment, or accept a lower-revenue entry period while the partner rebuilds team infrastructure. Few firms can make that commitment credibly during a search process.
Which practices are most exposed to the bench-gap objection?
Across our data, the Associate Bench & Practice Infrastructure Gap objection concentrates in the most execution-intensive practices. The top four are below.
| Practice area | Share of bench-gap objection discussions |
|---|---|
| Capital Markets | ~13% |
| Corporate / M&A | ~12% |
| Projects / Energy / Infrastructure | ~11% |
| Banking & Finance | ~10% |
Capital Markets leading the list reflects the staffing intensity of securities issuance work: a partner handling an active IPO pipeline or debt programme needs a dedicated associate bench that is already familiar with the documentation and process cadence. Arriving as the only capital markets partner at an office of primarily corporate and finance practitioners means rebuilding that cadence from zero. Partners who have spent years training a specific team around their deal velocity are rarely willing to make that investment twice at the same stage of their career.
In our interview data, the specific objection formulations in this category fall into three sub-types.
The bench-gap objection, anatomised — three structural sub-types in our data, each a different way the same dealbreaker shows up.
Franchise-team imbalance
Offices where partners significantly outnumber associates create a structural execution problem that no amount of cross-office borrowing resolves cleanly.
Infrastructure absence
In cross-border practices, a partner without access to European, Middle Eastern, or Asian office infrastructure through the target firm faces client quality risk on mandates that require multi-jurisdictional execution.
Unlike compensation or geography, it cannot be resolved by adjusting a number.
How book portability shapes the team-move calculation.
The decision to move with a team, alone, or not at all is not made in isolation — it is driven by the portability structure of the partner's book. Institutional books demand firm-level commitments. Portable books enable solo moves. Most books sit somewhere in between.
Across our interview corpus, portability assessments were completed for a subset of partners where a book of business was discussed. The distribution across the top team-move practices reveals the structural tension that makes this decision complex.

Private Equity — the outlier
The practice most likely to see partners whose relationships are structurally bound to the firm's institutional investor and fund-GP relationships. A solo PE move asks institutional clients to follow a tier change — many will not.
Sartori Global interview corpus ↗What does portability look like across the leading team-move practices?
| Practice area | n assessed | Highly portable | Partially portable | Low portability | Institutional |
|---|---|---|---|---|---|
| Corporate / M&A | 187 | 32% | 42% | 19% | 7% |
| Disputes / Litigation | 153 | 29% | 39% | 29% | 4% |
| Banking & Finance | 88 | 43% | 38% | 14% | 6% |
| IP | 84 | 25% | 42% | 26% | 7% |
| Capital Markets | 58 | 29% | 60% | 9% | 2% |
| Private Equity | 27 | 33% | 26% | 15% | 26% |
The portability distribution matters because it maps directly to what the partner needs from a destination firm. A highly portable partner — one whose client relationships are personal, well-documented, and will follow the move — can negotiate as an individual revenue asset. The infrastructure conversation is secondary to the deal terms. A partially portable partner, the largest cohort in almost every practice, needs some combination of personal client transfer and firm-level support to maintain and grow the book after the move. That is the cohort most likely to raise team-composition questions and most likely to encounter the bench-gap objection.
How a book’s portability decides what a partner needs from the destination firm — a structural decision tree, not a scoring model.
- Highly portable Negotiate as an individual revenue asset. Infrastructure is secondary to deal terms. A solo move works.
- Partially portable Need personal transfer and firm-level support. Most likely to raise team-composition questions — and to hit the bench-gap objection.
- Low portability / institutional The question inverts: not “can I bring my associates?” but “is the firm already staffed for institutional work that may follow?”
Partners with low portability or institutional books face a structurally different decision. In our data, Disputes/Litigation has one of the highest low-portability fractions across practices (29% among assessed partners). These are partners whose books are driven by institutional client relationships that sit with the firm — panel relationships, standing instructions, recurring litigation programmes. For them, the team-move question inverts: it is not “can I bring my associates?” but “is the destination firm already staffed to handle the institutional work that may follow if the firm relationship transfers?” The two questions sound similar but have different answers.
Private Equity is the outlier in this dataset. With an institutional fraction of 26% among assessed partners, it is the practice most likely to see partners whose client relationships are structurally bound to the firm’s institutional investor relationships, fund GP relationships, or long-standing mandates. A PE partner moving solo from a Magic Circle or Silver Circle firm to a mid-tier international platform is not just moving their personal relationship network — they are asking institutional clients to follow through a tier change, which many will not do. That structural difficulty explains why PE partner moves are both rare and high-stakes when they do occur.
The two questions sound similar but have different answers.
What should firms and partners do with this?
The team-move calculation is not just a logistics question. It is a deal-design question — one that requires both sides to be more specific about what they are committing to before a move is agreed.
Map your own book before you raise team composition — reactive framing is weaker.
What should a partner considering a move think about before raising team composition?
In our experience advising partners through lateral processes, the partners who handle team-composition conversations most effectively are those who have mapped their own book against three questions before starting any conversation with a destination firm.
The three-question book map — run it before the first conversation, not in reaction to the firm’s.
- 1How much is execution-dependent?Work that requires associates who know the client, the matter history, or the specific procedural approach.
- 2How many associates are truly portable?Willing to move, not conflicted, and at a stage of career where they have optionality.
- 3What is the minimum viable team?The composition needed to service the top 60% of current revenue in year one.
Partners who have not mapped these three questions typically raise team composition reactively — in response to a question from the target firm about book size — rather than proactively as a deal condition. That reactive framing is weaker. It means the partner is responding to the firm’s infrastructure assessment rather than setting the terms of what they need to execute. Across our interview data, partners who raise team composition as a condition early — in the context of their book analysis rather than as a general concern — are more likely to secure credible responses from target firms.
Reassurance does not close the bench gap. Specifics do.
What should a hiring firm do when a team-move partner raises bench-depth concerns?
The bench-gap objection in our data rarely resolves through reassurance alone. Partners who have encountered this objection before — and most experienced laterals have — know what an unconvincing answer looks like. Generic claims about the firm’s associate pipeline or cross-office staffing arrangements do not address the specific question: who will be on this deal in month two? Firms that handle this conversation well typically come to it with specifics: named associates who would be allocated, a committed timeline for associate hiring, or an agreed ramp arrangement where the partner is not expected to carry full billing-rate expectations before the team is rebuilt. Vague commitments to “work it out after you join” are, in our data, one of the more consistent triggers for a candidate withdrawing after an initially positive process.
| Weak answer | Credible answer |
|---|---|
| Generic pipeline claim | Named associates who would be allocated to the book |
| “Cross-office staffing” in the abstract | A committed timeline for associate hiring |
| “Work it out after you join” | An agreed ramp where full billing-rate expectations wait until the team is rebuilt |

How often do partners actually discuss bringing a team when exploring a move?
In our interviews with 2,600+ partners, team-move dynamics surfaced in just over a third of all conversations — approximately 35% of the pool (around 940 discussions). That figure almost certainly understates the underlying frequency: many partners only raise team composition once they are seriously engaged, not at first contact. The leading practices for team-move discussion are Corporate/M&A, Disputes/Litigation, IP, and Banking & Finance — practices where matter complexity and client relationship depth make solo execution genuinely difficult. A partner with a USD 3–5m book in a capital-intensive practice is far more likely to raise team composition than a regulatory partner whose core asset is a personal government-side relationship.
What do partners actually ask about bench depth and headcount before committing to a move?
Across our interview dataset, questions about team size, headcount, and office composition were the third most common question archetype, raised in roughly 9–10% of all question discussions. Partners ask how many equity partners versus counsel are already in the practice; whether they would be the only partner in the office; what the associate-to-partner ratio looks like; and whether the associate bench is junior, mid-level, or predominantly senior. The underlying concern is execution risk: a partner arriving with a $3–5m book who cannot staff a complex deal or trial without immediately hiring up is exposed from day one. The question is not academic — it is a proxy for whether the move is viable at all.
Is the 'associate bench gap' objection really a dealbreaker, or just a negotiating point?
It is a genuine dealbreaker in a material share of conversations. The Associate Bench & Practice Infrastructure Gap objection is the fourth most common classified objection in our dataset, appearing in approximately 9% of classified objections across around 2,789 classified discussions. It is most acute in Capital Markets, Corporate/M&A, Projects/Energy/Infrastructure, and Banking & Finance — practices where a partner arriving with a large book cannot execute without immediate staffing. The specific concern takes several forms: insufficient associate depth to handle mega-deal volume; franchise-team imbalance (too many partners, too few associates); missing specialist sub-team infrastructure; or inadequate cross-border coverage outside the target firm's home market. When a partner raises this objection, it rarely resolves without a credible hiring commitment from the firm.
Which practices generate the most team-move discussions in partner interviews?
Corporate/M&A leads by a wide margin in our data, with around 206 team-move discussions — more than 60% larger than the next largest practice. Disputes/Litigation is second (approximately 128 discussions), followed by IP (around 82), Banking & Finance (around 78), Capital Markets (around 48), and Private Equity (around 42). The pattern reflects matter complexity and staffing intensity: a disputes partner handling multi-jurisdictional arbitration, a corporate partner running a mid-market M&A programme, or a capital markets partner needing a dedicated associate bench cannot realistically move and maintain client relationships without portable team support or an immediate hire at the destination firm. Solo moves are proportionally more common in regulatory, tax, and advisory practices where the core asset is the partner's personal knowledge and relationships rather than execution infrastructure.
Does portability of the book differ between partners who move with a team and those who move solo?
Our data does not split portability assessments cleanly by team-vs-solo, but the portability distributions by practice strongly imply it. Among partners whose book portability we assessed in Corporate/M&A — the top team-move practice — 32% are rated highly portable versus 19% low portability, with the largest cohort (42%) partially portable. In Disputes/Litigation, low portability accounts for 29% of assessed partners, which connects directly to the institutional-client problem: work that is panel-driven or follows the firm rather than the partner cannot be moved without the team relationships that helped secure it. Partners with genuinely institutional books — where the work follows the firm, not the individual — are structurally more likely to need firm-level commitments (additional hires, infrastructure investment) as the price of a move.
