Prince William is reportedly distancing himself from one longstanding royal tradition, having turned to the legal team once used by his late mother, Princess Diana.

According to surprising new claims from the Mail, the heir to the throne has recently chosen to work with the prominent UK law firm Mishcon de Reya to manage some of his private legal matters—a firm that previously represented Princess Diana during a pivotal moment in her life.

Back in August 1996, Diana enlisted the help of Mishcon de Reya to oversee the formal end of her marriage to Prince Charles, now King Charles III. Specifically, she was represented by Anthony Julius, the firm’s deputy chairman, throughout the high-profile divorce proceedings.

Following her untimely death in 1997, Julius went on to become the vice-president of the Diana, Princess of Wales Memorial Fund—a charity he helped found—until it closed its doors in 2012.

Diana, who was also mother to Prince Harry, died in a tragic car crash on August 31, 1997, alongside her partner Dodi Fayed, after a high-speed chase involving paparazzi ended in a fatal collision in the Pont de l’Alma tunnel in Paris. Fayed also lost his life in the crash.
