Law Firm Hire News vs Partner Moves: January Gap, Autumn Match

Sartori & Partners data show law firms published 3,649 hire announcements in the 12 months to October 2026, while 3,904 partners moved from one law firm to another. Over a full year the two counts sit close together. Month by month, law firm lateral hire announcements follow the partner count with two clear breaks. In January, partners change firms faster than firms announce hires. From late summer into the winter, the announcements catch up and often pass the partner count. For a firm that reads rivals' press pages to judge the partner market, both breaks change what the news feed is worth.

The annual figures are close enough to use as a rule of thumb. Hire announcements equaled 93.5% of lateral partner moves over 12 months, a gap of 255. Partners made 27.7% of all lateral moves in the period, so the volume of hire news lines up with the partner tier rather than with the whole market of associates, counsel and partners.

Most single months hold the same line. June 2026 counted 352 hire announcements and 350 partner moves, close to a one-for-one match. The two counts are not the same people: a hire release can cover a counsel or a senior associate, and one release can name a group of lawyers joining together. Still, the volume of hire news rises and falls with the volume of partner moves in most months, which is what makes the exceptions worth reading.

For a hiring partner, the practical reading is simple. Over a full year, the press feed gives a fair sense of how many partners are moving. Inside the two seasons below, it gives a misleading one, and in opposite directions.

January is the year's busiest month for lateral moves, and the news does not keep pace. In January 2026, 496 partners changed firms while firms published 350 hire announcements. Hire news equaled 70.6% of the partner count that month, against 93.5% across the full 12 months.

The gap is not a one-year accident. In the Sartori & Partners lateral database, January 2025 counted 465 partner moves against 376 hire announcements, and January 2024 counted 398 against 292. In each of those three years, January is the month in which the partner count ran furthest ahead of the news.

Partners also take a larger slice of the market at the start of the year: they were 31.8% of January 2026 lateral moves, against 27.7% over 12 months. A firm leader who counts rival announcements in the first quarter will undercount the partners who moved. And the partners who started in January were in talks through the autumn, so the January news feed reports the end of searches that rivals opened months before.

The second half of the year turns the comparison around. September 2026 counted 383 hire announcements against 346 lateral partner moves, 37 more announcements than moves. July and August 2026 went the same way, with 324 and 340 hire announcements against 311 and 316 partner moves.

September did the same in the two years before. September 2025 counted 374 hire announcements against 356 partner moves, and September 2024 counted 314 against 293. December is the sharpest case: in December 2025, firms published 186 hire announcements while 146 partners moved, so hire news equaled 127.4% of the partner count. December is also the quietest month of the year for moves, with 638 in all, so its ratio shows a direction more than a size.

The category mix helps explain the swing. In January 2026 firms also published 238 promotion announcements, against 24 in September 2026, so the start of the year shares its news calendar with partner classes. September, by contrast, is heavy on associate hiring: associates were 61.1% of September 2026 lateral moves, and hire releases are not limited to partners. For a firm leader, a busy autumn news feed slightly overstates the partner market, while a thin January feed understates it by much more.

Three limits apply. First, the units differ: an announcement is a release a firm chose to publish, while a move is a lawyer whose start date at the new firm is known to the month. Second, the timing differs: a release can appear when a hire is agreed, while the move is dated by its start. Third, the newest month reads low. October 2026 shows 304 partner moves and 213 hire announcements, and both figures are still filling in, so October is left out of the monthly reading here.

Sartori & Partners records lateral moves from public law-firm announcements, firm websites and professional profiles, checked monthly. That is why the move record can run ahead of the press page in January: a partner who appears on a new firm's website is counted whether or not the firm issued a release. Across the 12 months, firms announced 255 fewer hires than partners moved, and January 2026 alone accounts for 146 of that shortfall.

First, read a rival's quiet January as noise. With 496 partner moves against 350 hire announcements in January 2026, the partner market at the start of the year is larger than the news shows, and a rival that issued no release may still have added partners.

Second, plan partner searches on the move record, not on the announcements. The January peak is the end of autumn negotiations. A firm that opens conversations when the January releases appear has already missed that window and is bidding for the candidates who start in the spring.

Third, expect the autumn feed to look busier than the partner market. When hire releases pass the partner count, as in September 2026 with 383 announcements against 346 partner moves, part of that volume is counsel and associate hiring. Size a rival's partner bench from its partner arrivals, not from its release count.

Fourth, use the annual ratio as a check, not a census. Hire news at 93.5% of partner moves says the press page covers partner activity at roughly its real scale over a year. It never says so month for month, and the months that matter most for partner hiring are the ones where it is furthest off.
