How to Hire In-House Counsel: 76.7% of Movers Are Associates

Most companies working out how to hire in-house counsel end up recruiting from a law firm, and the lawyers who make that move follow a clear pattern. Sartori & Partners data show that 953 lawyers left a law firm for a company between May and October 2026, and 76.7% of them were associates. Most came from the largest firms and from a short list of cities. This guide reads those moves from the buyer's side: which level to target, which firms to source from, which cities to search, and what the pattern means for a shortlist.

Level is the first decision in any in-house search, and the market has already settled it for most companies. In the Sartori & Partners lateral database, associates made up 76.7% of moves from law firms to companies over those six months, about three in four. Counsel, the law-firm title that sits between associate and partner, made up 12.0%. Partners made up 11.0%.

Moves between firms look different. Associates took 58.5% of lateral moves from one law firm to another over 12 months, 18.2 points below their share of moves to companies. Partners took 27.7% of lateral moves, 2.5 times their share of moves in-house. A partner who changes jobs usually changes firms. An associate who changes jobs is far more open to a company.

The consequence is a default target. A role written for a mid-level or senior associate fits the pool that already moves, and it will draw the widest field. A general counsel or head of legal role pitched only at partners draws from a much thinner pool: plan for a longer search, or open the role to counsel, whose share of moves in-house is close to their share of moves between firms.

The second decision is where to look. Firms of 1,000+ lawyers were the firm left in 59.3% of moves to companies. Firms of 400-999 lawyers supplied 24.1%, firms of 150-399 lawyers 12.3% and firms under 150 lawyers 4.3%.

Read that comparison with care. The in-house column counts the size of the firm a lawyer left; the lateral column counts the size of the firm a lawyer joined, which is how lateral moves are classed. On that basis, firms of 1,000+ lawyers took 53.6% of lateral moves over 12 months, 5.7 points under their share as a source of in-house hires. Counted by the firm left instead, the same class was the starting point of 57.3% of lateral moves where both firm sizes are known. The gap holds on either reading.

The smallest firms show the reverse. Firms under 150 lawyers took 9.7% of lateral moves but supplied 4.3% of in-house hires, a share 2.3 times smaller.

For sourcing, start with lawyers at the largest firms in the practice you need. They are trained on large matters and demanding clients, which is usually why a company wants them, and they are the group most willing to move. The flip side is pay: your offer is measured against a large-firm salary scale, so set the budget before the first interview. Candidates from firms of 400-999 lawyers are the natural second pool, and often closer to the generalist work of a small legal team.

City is the third filter. New York was the city left in 16.1% of moves to companies, ahead of London at 8.2% and Washington, DC at 7.3%. San Francisco followed at 5.5% and Chicago at 4.0%.

The useful test is each city against its share of lawyers who left for another firm. San Francisco was the city left in 5.5% of in-house moves against 2.9% of lateral departures, 1.9 times its lateral share. Washington, DC ran 2.3 points above its lateral share, and New York 2.9 points above. Los Angeles went the other way, at 3.0% of in-house moves against 4.1% of lateral departures. The in-house figures cover May to October 2026 and the lateral figures 12 months, so shares are compared, not counts.

If your legal team sits in New York, Washington or San Francisco, the local pool is deep and in-office terms are realistic. Elsewhere, expect to recruit from those hubs and to pay for relocation or accept hybrid work. Houston and Dallas counted 22 and 22 moves in-house in six months: a company there competes for a handful of candidates a month.

In the Sartori & Partners figures, 772 companies hired the 953 lawyers who left firms over those six months, 1.2 hires per company. In-house hiring is mostly one seat at a time. Over the same months, lawyers moved in-house 13.1 times for every hundred lateral moves between firms. The associate on your shortlist is far more likely to be weighing an offer from another firm than from another company.

That shapes the pitch. A firm offers a known path to partnership and a higher salary; a company has to offer something the firm cannot: broader work, closer contact with the business, predictable hours, and a title that means something inside the company. On practice, Corporate & M&A featured in 33.2% of in-house moves against 20.7% of lateral moves, so deal lawyers are a well-trodden route in-house.

Speed matters as much as the offer. A lateral move between firms is often decided within weeks once a candidate is in play. A company that needs several rounds of interviews across the business should fix the dates in advance and make the offer within days of the last meeting.

Write the role for a mid-level or senior associate unless the job truly needs a partner: associates are 76.7% of the lawyers who make the move, and a partner-only brief cuts the field to a fraction of that. Open a senior role to counsel as well as partners. Source first from firms of 1,000+ lawyers, then from firms of 400-999 lawyers, and price the offer against their pay. Search New York, Washington and San Francisco even for a role based elsewhere, and decide early what relocation or remote work you will accept. Run a short, fixed process, because the competing offer is usually from a law firm that moves quickly.
