Insurance Coverage Lawyers: A Pool Rooted in Small Firms

Anyone planning insurance coverage lawyers lateral hiring should start with one question: where do these lawyers sit before they move? Sartori & Partners data show that over 3 years, 23.0% of insurance coverage movers whose previous firm is known came from firms under 150 lawyers, against 11.4% of movers across all practices. That is 2.0 times the market's share. The hiring side has its own tilt: firms of 150-399 lawyers took 23.7% of the 417 coverage arrivals in the 12 months to October 2026, against 13.3% of all arrivals, while firms of 1,000+ lawyers took 43.2%, below the market's 53.6%. Coverage talent is grown in smaller firms more than in most practices, and mid-size firms compete for it harder than they do elsewhere.

The difference sits at the bottom of the size scale. In the Sartori & Partners lateral database, firms under 150 lawyers were the previous firm for 23.0% of insurance coverage movers over 3 years, 11.6 points above the 11.4% seen across all practices. Firms of 1,000+ lawyers were the previous firm for 37.5% of coverage movers, against 56.6% in the market. Across Insurance & Reinsurance as a whole the small-firm figure is 20.6%, so coverage sits above its own practice as well. Reinsurance, the other insurance speciality in the practice, sits at 11.4% and draws 63.2% of its movers from firms of 1,000+ lawyers.

For a larger firm the consequence is direct: firms of 1,000+ lawyers are still the largest single source, but firms of 150-399 lawyers and under 150 lawyers supply far more of the pool than they do in the market. A search list built only from firms of similar size misses the part of the pool where coverage runs deepest against the market. For a small coverage firm, the same figure says its lawyers are the ones other firms will call first.

The size mix of the hiring firms departs from the market too. Firms of 150-399 lawyers took 23.7% of insurance coverage arrivals in the latest 12 months, 1.8 times their 13.3% share across the market. Firms of 1,000+ lawyers took 43.2%, against 53.6% market-wide and 46.1% in the Insurance & Reinsurance practice. Firms under 150 lawyers took 9.9% of coverage joiners, close to the market's 9.7%; over 3 years they took 11.5%, against 8.6%.

Coverage moves also bring promotion more often than the average move: 18.0% came with a step up in title, against 12.9% market-wide. Fewer coverage movers change city, at 18.2% against 20.5% for all moves, so the candidate is usually local. A firm of 150-399 lawyers is a real buyer in this speciality, and a partnership offer is often part of the price of a move.

Within its own practice, coverage leans further toward mid-size buyers. Firms of 150-399 lawyers took 18.5% of Insurance & Reinsurance joiners in 12 months, against 23.7% in coverage. In reinsurance, firms of 1,000+ lawyers took 58.7% of joiners over the same period, so the two insurance specialities are hired by different kinds of firm.

For a firm of 1,000+ lawyers, coverage depth is contested by mid-size firms more than in the practice as a whole. Expect to compete with them on rates and partnership timing, not only with other large platforms, and move early once a candidate is identified.

The work itself explains part of the pattern. Insurance coverage accounts for 54.2% of lateral moves in the Insurance & Reinsurance practice over 12 months, so its habits shape the whole group. Of the 479 coverage matters on record over 3 years, 98.3% were disputes and investigations, and insurance companies were the client industry on 62.6% of them. In reinsurance the insurer share reaches 84.0%.

Carrier-side coverage and defense work is a volume business, and much of it goes to firms that run lean on rates. That gives small firms a steady stream of files on which younger lawyers learn the trade. For a larger firm the consequence is practical: a lateral from that pool often arrives with insurer relationships, so test which carriers follow the lawyer before pricing the hire.

The pool is also getting thinner. Insurance coverage hiring fell 12.3% year on year, from 478 moves to 419 across the settled 12-month windows. In the Insurance & Reinsurance practice, with 643 moves in the earlier window and 659 in the later one, hiring held flat (+2.5%). Across all practices lateral hiring rose 9.0%. Partner hiring in coverage held flat (-9.2%), at 129 against 142.

Demand is concentrated as well. The top 10 coverage hirers took 36.8% of moves in 12 months, against 12.9% for the market's top 10, and 140 firms hired at least one coverage lawyer. The list below shows who took the most.

Fewer moves and a short list of active buyers mean each credible candidate is seen by several firms at once. A firm that waits for a coverage partner to surface on the open market will usually meet that lawyer late, with competing terms already on the table.

Three points follow. First, build the search list from firms under 150 lawyers: they were the previous firm for 23.0% of coverage movers over 3 years, against 11.4% in the market. Second, expect competition from firms of 150-399 lawyers, which took 23.7% of coverage joiners in the latest 12 months, against 13.3% across the market. Third, plan for a smaller market: coverage hiring fell 12.3% over the year, so a mandate opened now should allow for a longer search and a candidate weighing more than one offer.

For a small firm the same figures read as a warning. Firms of its size were the previous firm of coverage movers 2.0 times as often as in the market, and mid-size firms hire in this speciality well above their market share. Partnership timing, origination credit and a clear path to carrier panels matter more in this speciality than in most.
