Making Partner Within 8 Years: 31.8% in Private Equity, 10.1% in Trade

Sartori & Partners data show that the chance of making partner within 8 years turns on the practice far more than on the firm. Over five years of promotions, 31.8% of new private equity partners had reached the title within 8 years of their first year of practice, against 23.2% across all 10,427 promotions on record. In corporate and M&A the share was 29.5%. In international trade it was 10.1%.

Time to partner here runs from the first year of practice to the promotion, so it measures a career rather than tenure at one firm. The records come from public law-firm announcements, firm websites and professional profiles, checked monthly. This report looks at the early end of the track, the share promoted within 8 years and within 12 years, rather than the midpoint. The midpoint barely separates one practice from another. The early share does.

The gap at the fast end is wide. Private equity's 31.8% sits 8.6 points above the market share of 23.2%, which makes an early promotion 1.4 times as common as in the market as a whole. Corporate and M&A, much the larger practice with 1,990 promotions over five years, runs at 29.5%. Capital markets follows at 26.8%. Litigation and disputes, the biggest promoting practice with 4,725 cases, sits below the market at 21.1%.

These are also the practices with the deepest lateral partner market. In the Sartori & Partners lateral database for the last 12 months, corporate and M&A was involved in 22.3% of all partner moves and private equity in 12.2%. The two facts work together. Strong deal associates are named partner early where they sit, so the pool of senior associates thins faster than class sizes suggest, and the partner pool holds lawyers with fewer years of practice than a litigation partner of the same title.

For a firm hiring into private equity or corporate, that sets the clock. A senior associate who is still unpromoted late in the track is rarer here than in most practices, and a lateral partner from these groups may carry the title with a short career behind it. Judge the book of work, not the years.

At the other end, international trade made 10.1% of its partners within 8 years, financial services regulatory 10.2% and white collar, investigations and criminal 12.8%. Private equity promotes early 3.1 times as often as trade. The gap between private equity and white collar is 19.0 points.

The bases differ in weight. White collar rests on 486 promotions over five years, a solid count. Financial services regulatory rests on 197 and trade on 99, so their shares are rough sizes: the order is reliable, the decimal point is not. All three are practices where lawyers often spend years in government, at a regulator or in a prosecutor's office, and the clock here counts from the first year of practice, wherever it was spent.

The lateral market in these groups is thin as well. Over the last 12 months white collar was involved in 5.1% of lateral partner moves, financial services regulatory in 2.9% and trade in 1.1%. A firm that needs a partner here finds few made early inside other firms and few on the move. An associate in these groups without the title in the eighth year is on the normal path, not behind it.

Counted within 12 years, the picture changes. White collar made 72.8% of its partners within 12 years, only 2.6 points short of the market's 75.4%. Financial services regulatory reached 72.1%. These practices do not promote late overall; they promote in a tighter band after the eighth year. The gap between private equity and white collar narrows from 19.0 points within 8 years to 13.9 points within 12 years.

Immigration and family are a different case. Each made 54.5% of its partners within 12 years, 20.9 points below the market. Their shares within 8 years, 14.8% and 18.8%, are not the lowest of any practice; the difference is the long tail, with the slowest quarter of immigration promotions coming at 16.0 years or later. Family rests on 48 promotions and immigration on 88, so read both as rough sizes.

Trade keeps its distance at both lines, with 65.7% made within 12 years. For a firm recruiting in immigration, family or trade, the practical partner candidate is often a counsel or a senior associate with a long record, and a promise of partnership on a deal-practice timetable will not match what the practice delivers.

Set against the other cuts in Sartori & Partners records, practice is the variable that matters. By size of firm, the share made partner within 8 years runs from 21.8% at firms of 1,000+ lawyers to 27.1% at firms of 150-399 lawyers, a spread of 5.3 points. By year of promotion, the market share was 24.3% in 2022 and 23.1% in 2025, 1.2 points apart. Between private equity and international trade the spread is 21.7 points.

The 2026 figure reads lower, at 17.5%, but it covers promotions through May only, a partial year. For partner planning, the benchmark to use is the practice one. A white collar group promoting early at the market rate of 23.2% would be far ahead of its own practice; a private equity group at the same rate would be behind its peers.

Promotion inside the firm is not the only way to partnership. Across all practices, 12.9% of lateral moves in the last 12 months were a step up in title, such as associate or counsel to partner. Partners made up 27.7% of all lateral moves in the same window.

Where the internal early track is narrow, that route carries more weight. A senior white collar or regulatory associate who sees few early promotions in the practice has a reason to listen to an offer that brings the title forward, and a firm able to make that offer has a real edge in recruiting. In private equity and corporate the position is reversed: many strong associates are made partner where they are, so an offer has to beat a promotion that may already be in sight.

Benchmark by practice. Over five years of promotions the share of partners made within 8 years runs from 31.8% in private equity to 10.1% in international trade, and the market's 23.2% fits neither end. Use the practice figure when judging a candidate's progress, a group's promotion record, or a timetable written into an offer.

Time the search to the track. In private equity and corporate, look for future partners among mid-level associates, because 29.5% of corporate partners are named within 8 years. In white collar and financial regulation the decision falls later and in a narrower band: 72.8% of white collar partners were named within 12 years, so the strongest candidates are decided after the eighth year.

Expect long careers in immigration and family. With 54.5% of partners in each made within 12 years, the realistic hire is a counsel or senior associate with a long record, and the bases are small enough that a few firms' choices can move the share.
