Where Lawyers Go When They Leave Firms: 86.1% Join Another Firm

Ask where do lawyers go when they leave a law firm, and the answer for the last 6 months is short: mostly to another law firm. Sartori & Partners data show that of the lawyers who left a firm between May and October 2026, 86.1% joined another firm, 11.3% moved in-house and 0.4% went into government. In counts, that is 7,281 lateral moves against 953 moves in-house and 37 into public service. For a firm that wants to keep its lawyers, the first competitor is a rival firm, not a client's legal department. This report sets the destinations side by side, then looks at who takes each route and what that means for a firm's retention plan.

The split is lopsided. In the 6 months to October 2026, 7,281 lawyers left one firm for another, 7.6 times the 953 who joined a company or another in-house employer. For every hundred lateral moves, 13.1 lawyers went in-house. Two other exits are small: 37 lawyers (0.4%) joined government and 173 (2.0%) left law practice for another reason.

The two in-house figures measure the same flow against different bases. The share of 11.3% counts in-house moves against every lawyer who left a firm; the rate of 13.1 per hundred counts them against lateral moves alone. Read either way, in-house is the minority route. In the table, "out" means a lawyer who left law practice without joining a firm, an in-house employer or government.

The practical consequence is about where a firm spends its retention effort. A plan built mainly to match in-house offers addresses 11.3% of departures. The plan that matters holds a lawyer against an offer from a competing firm: pay set against the firms that hire in the same practice, a credible path to partnership, and a platform that supports the lawyer's clients.

The level mix separates the two exits. In the Sartori & Partners lateral database, partners accounted for 11.0% of moves in-house since May 2026, or 105 partners, while they made 27.7% of lateral moves in the 12 months to October, a gap of 16.7 points. Associates carry the in-house flow: they were 76.7% of in-house moves, against 58.5% of lateral moves. Counsel weigh about the same on both routes, 12.0% in-house and 12.7% lateral.

The two windows differ, because moves in-house are tracked in full only from May 2026, so read the gap as a direction rather than an exact figure. The direction is clear. A partner who resigns is, in most cases, joining a competitor and may bring clients along. An associate who resigns has a real in-house option as well as a lateral one. Partner retention is therefore a contest between firms; associate retention has to answer both a rival firm and a company.

Competition for partners is rising, not easing. Lateral partner moves rose 8.4% in the 12 months to September 2026, with 3,858 moves against 3,558 in the prior 12 months. In the 12 months to October, 1,291 firms made at least one lateral hire, so the pool of possible bidders for a partner is wide.

The firms above hired more partners than they lost to other firms over 12 months; the band is the net figure, not total hiring. Net flow counts partners only, since firms that train their own associates expect some of them to move on. For a managing partner, this list is a short guide to the platforms most likely to approach the firm's own partners, and to the terms those partners will hear. Partners made 27.7% of all lateral moves over 12 months, a share large enough that a firm should expect regular approaches at that level.

In-house demand shows no sharp season in the 6 months on record. Moves in-house ran from 117 in May to 188 in June and 187 in September, an average of 159 a month. Lateral moves between firms ran at a far higher level: 1,359 in June and 1,337 in September.

October reads low on both routes, 125 in-house and 926 lateral, because start dates are confirmed with a delay. For planning, the in-house flow is a constant background rate rather than a wave to prepare for. The lateral calendar, with its own busy months, is the one that should set the timing of compensation reviews and partner conversations.

Firms of 1,000+ lawyers supplied 59.3% of moves in-house where the size of the old firm is known, and firms under 150 lawyers supplied 4.3%. The same large firms took 53.6% of lateral arrivals in the 12 months to October, so they are at once the main recruiters of lateral talent and the main source of in-house counsel.

Their people also leave more often. Measured on firm websites since April 2026 and annualized, the median firm of 1,000+ lawyers loses 14.8% of its lawyers a year, against 13.2% across the 525 firms measured. A large firm faces both contests at once: rival firms for its partners, companies for its associates. A firm under 150 lawyers faces almost only the lateral one.

Sartori & Partners data point to four concrete steps. First, benchmark retention against firms, not companies: with 86.1% of leavers joining another firm, pay, origination credit and partnership terms are judged against the firms hiring in the same practice and city. Second, record where each leaver goes. If more than 11.3% of a firm's departures go in-house, or more than 86.1% go to rivals, the firm differs from the market and should know why. Third, treat associates who join companies as future clients: an alumni program costs little and keeps that route working for the firm. Fourth, watch the firms with the largest net partner gains, because they are the bidders a partner is most likely to hear from, in a lateral partner market that rose 8.4% over the latest settled 12 months.
