International Arbitration & Public International Law: promotions and time to partner

Sartori & Partners data record 41 partner promotions in International Arbitration & Public International Law from June 2025 to May 2026. Promotions are confirmed about five months late, so this window ends earlier than the lateral figures. Over the same 12 months that is 0.79 promotions for every lateral partner hired, against 0.79 across the market: the same balance as the market.

Across five years of promotions, the median time from first year of practice to partner is 11.0 years, with the middle half between 9.0 years and 14.0 years. The market median is 10.0 years, so the track here runs longer. The median rests on 132 promotions.

On settled windows lateral partner moves in International Arbitration & Public International Law went from 51 to 59 (+15.7%), a change inside the noise of the two counts, so we read it as flat.

Firms in International Arbitration & Public International Law lean on internal promotion; a lateral partner here is an exception to plan and justify.
