Private Client Path to Partner 2026: Longest Among Larger Practices

The middle of the private client partner class is only a little slower than the market. The back of it is much slower. Sartori & Partners data show that the slowest quarter of lawyers promoted to partner in private client and estates over the last 5 years took 14.0 years or more from their first year of practice, against 12.0 years across all practices. Only 66.2% made partner within 12 years, where the market figure is 75.4%. For a firm asking how long to make partner in trusts and estates, the honest answer has two parts: a median of 11.0 years, and a long tail that no other large practice matches. That tail shapes who is available to hire, who is still waiting for the title, and where the experienced lateral candidates sit today.

The clock here runs from the first year of practice to the promotion, measured on 216 private client promotions recorded over 5 years. At the fast end the practice looks ordinary: 19.4% were promoted within 8 years, close to the market's 23.2%, and the quickest quarter made it in 9.0 years or less, the market's own 9.0 years.

The gap opens after the median. Within 12 years the private client share trails the market by 9.2 points, a large share of new partners who had practiced longer than that before the title came. The slowest quarter waited 2 years longer than the market's slowest quarter. Those late promotions pull the private client mean to 12.1 years, 1 year above the market's 11.1 years. For a promotion committee, the conclusion is simple: a senior private client associate not yet promoted within 12 years is not an outlier in this practice, and a firm that treats that mark as a deadline will push out lawyers its rivals would still promote.

Set against the other practices with at least 54 partner promotions in the year to May 2026, private client stands at the end of every slow-track measure but the median. In the Sartori & Partners promotions record, no other practice in that group has a slowest quarter beyond 13.0 years, the figure for litigation, tax and several others; corporate and M&A sits at 11.0 years. The nearest share within 12 years is projects and infrastructure at 66.9%, and the highest mean after private client is 11.7 years. The median of 11.0 years is shared with regulatory work, projects and financial services regulatory, so the difference is in the tail, not the center.

Two smaller practices do run longer: family and immigration, each with a slowest quarter of 16.2 years, on far fewer promotions. The closer comparison is tax, tagged on 64.4% of private client lateral moves. Tax partners reach the title faster, with 72.4% promoted within 12 years. A trusts lawyer and a tax lawyer often sit in the same group and serve the same families, yet the trusts lawyer tends to wait longer. Part of the reason is the work itself: estate planning, trust administration and probate reward years of client relationships, and many firms want a private client partner to bring or hold a book of family clients before the vote. That is a firm-level choice, and it means a firm that promotes on merit at the market's pace can win candidates simply by not making them wait.

A long track does not mean firms stop growing their own. Between June 2025 and May 2026, firms made 71 private client lawyers partner, or 0.76 promotions for every lateral partner hired in the same months, a shade under the market's 0.79. Lateral partner hiring in the practice held flat (+21.1%), at 109 moves against 90 a year earlier; on counts this small that gap is within the noise, while partner moves across all practices rose 8.4%.

Partners are already a large part of the private client flow. They made up 32.6% of its lateral moves in the latest 12 months, against 27.7% across the market. Put next to the long wait for promotion, that mix tells a firm where the shortcut lies: when the home-grown route runs this long, buying a partner with a book is the faster way to add capacity, and many firms already take it.

The second finding concerns where experienced private client lawyers move. Sartori & Partners figures show firms of 1,000+ lawyers took 18.9% of private client lateral moves in the latest 12 months, against 53.6% across all practices. Firms of 400-999 lawyers took 38.1%, and firms under 150 lawyers 18.9%, against 9.7% market-wide. The pattern is not new: over three years the largest firms took 19.3% of the practice's moves.

The supply side tilts the same way. Over three years, 30.1% of private client movers left a firm of 1,000+ lawyers, against 56.6% for the market. A search that only canvasses the largest firms will miss most of the candidates. The deeper pool is in firms of 400-999 lawyers and in smaller private client groups, often regional, where senior associates and counsel may have waited longest for a partner vote.

Plan promotions on the practice's own clock. With 66.2% of new partners promoted within 12 years, a firm should expect many of its eventual private client partners to need longer, and should tell them so early. A lawyer who hears nothing and is not promoted within 12 years is the one rivals call.

Use the tail as a recruiting pool. The slowest quarter of the class waited 14.0 years or more, so a strong senior associate or counsel at another firm who is still waiting is a realistic target, and a firm that can offer a clear path to the title has an argument that pay alone does not match.

Search where the moves happen. With only 18.9% of private client moves going to the largest firms, the competition for a private client partner comes mostly from mid-size and smaller firms. A large firm building the practice is bidding against those firms, and its pitch should rest on platform and clients rather than on pay.
