One of the family law greats – she became Britain’s first female (and the youngest ever) senior partner of a City law firm in 1998 – Diana Parker has been at the top of her game for more than 30 years now. The charismatic Parker has a particularly strong reputation for her strategic negotiation of financial settlements for UHNWs, out of court and out of the press. It’s all about striking a fine balance at a time when people are prone to be in denial and self-delusion. ‘That’s why a lawyer’s job is so tricky. You have to constantly be providing a reality check,’ she explains. Her cases are invariably vast – including Britain’s first billion-pound divorce, in which she spared Chris Hohn’s business from his final settlement.
