Compliance Counsel From Law Firms: Investigators Move, Regulators Stay

A general counsel who sets out to hire compliance counsel from a law firm is fishing in two pools that behave very differently. Sartori & Partners data show that white collar and investigations lawyers left firms for companies at 16.2 for every hundred lateral moves between firms in the 6 months to October 2026, and antitrust lawyers at 15. Regulatory and compliance lawyers moved at about 7.9, and financial services regulatory lawyers at about 5.6. The rate for the whole market was 13.1. Investigators sit above the market line; regulatory specialists sit well below it.

The spread between the four practices is wide. White collar lawyers went to companies at 2.1 times the regulatory and compliance rate, and antitrust lawyers at 2.7 times the financial services regulatory rate. In plain counts, 42 white collar lawyers and 30 antitrust lawyers joined a company over the six months; the two regulatory practices each sent too few to print.

The pattern fits the work. An investigations practice runs internal inquiries, answers regulators, and builds remediation plans, which is much of what a company compliance function does every week. White collar was involved in 4.4% of all moves from firms to companies, above its 3.4% share of lateral moves between firms. For a company, the practical reading is simple: an investigations lawyer is the compliance hire most likely to say yes.

Level explains much of the gap. Associates made up 76.7% of moves from law firms to companies, and partners only 11.0%. Companies recruit mostly below partner, so a practice whose movers are partners has fewer people at the level a legal department usually buys. In the Sartori & Partners lateral database, associates were 40.5% of regulatory and compliance moves over 12 months, against 58.5% across all practices, a gap of 18.0 points.

Financial services regulatory leans further still: associates took 37.6% of its lateral moves and partners 47.9%. Antitrust sits at the other end, with associates at 55.0%, and white collar falls between at 45.2%. Ranked by associate share, the four practices fall in nearly the same order as their rates of moving to companies; only white collar and antitrust swap places at the top. A company that wants a regulatory specialist is often asking a partner to give up a partnership, and the offer has to be built for that person, not for a senior associate.

The regulatory partners a bank or payments company would want are the same people law firms are paying for. Financial services regulatory partner moves between firms rose 40.2% year on year, from 82 to 115 in the settled 12-month windows. Partner moves across the whole market rose 8.4% over the same windows, from 3,558 to 3,858. All financial services regulatory lateral moves rose 19.6%, from 204 to 244.

In general regulatory and compliance work the picture is calmer: partner moves held steady, at 176 against 159, a change of +10.7% that is flat at counts of this size. The firms below hired the most financial services regulatory partners over 12 months; they are the competing bidders for the same people.

For a company, this means a financial services regulatory partner who takes your call may well be hearing from other firms too. Expect a counteroffer, move quickly once the person is serious, and price the role against a partnership, not against an in-house salary band.

Moves from firms to companies are tracked in full only from May 2026, so every rate in this report covers 6 months. Across all practices that window holds 953 moves to 772 different companies. White collar supplied 42 of them and antitrust 30. In regulatory and compliance and in financial services regulatory the counts fall below the level Sartori & Partners publishes, so their rates of 7.9 and 5.6 are rough sizes. They show the direction clearly; they are not a ranking tool.

Monthly volume across the market ranged from 117 to 188 over the six months, an average of 159 a month. Read the regulatory figures as few move, not as an exact rate: the gap to white collar is wide, but its precise size will shift as more months are added.

Both pools concentrate in the capital. Washington, DC took 19.7% of white collar lateral arrivals, an index of 351 where a hundred is the market's share. The index reads 298 for regulatory and compliance and 268 for financial services regulatory. Antitrust is the exception: its weight sits in Brussels, at an index of 1,258.

Washington, DC was also the city of 7.3% of the lawyers who left firms for companies, against 5.0% of the lawyers who left one firm for another. Regulatory lawyers also stay put: financial services regulatory lawyers changed city in 14.0% of lateral moves, against 20.5% across all practices. A company outside Washington should plan for a hybrid arrangement or a relocation package, rather than expect a regulatory specialist to move on a standard offer.

First, decide which compliance job you are filling. If the role is investigations-led, with internal inquiries, whistleblower reports and regulator requests, recruit from white collar and antitrust benches, where moves to companies ran at 16.2 and 15 per hundred lateral moves. These lawyers already move in-house more than the market does, and the associate tier is deep enough to hire below partner.

Second, if the role is regulatory-led, with licensing, supervisory exams and rule changes, expect a senior hire. Associates are only 40.5% of the regulatory and compliance lateral bench, so the realistic candidate is a counsel or a partner, and the package must reflect that. Third, in financial services regulatory, budget for competition from firms: partner moves between firms rose 40.2% year on year. Fourth, consider the hybrid route. Hire an investigator who has worked opposite regulators, and add regulatory depth through outside counsel until the internal bench matures. The Sartori & Partners figures point the same way: investigators are the pool that moves, and a regulatory partner who is not looking to leave makes for a long search.
