The story
Mourant is the result of successive mergers of various law firms, most recently that of Mourant du Feu & Jeune and Ozannes in 2010.
In the same year, the Mourant group sells Mourant International Finance Administration to State Street, Mourant Private Wealth to RBC and Mourant Equity Compensation Solutions to HBOS. In 2018, it changed its name from "Mourant Ozannes LP" back to "Mourant LP".
