Who qualifies for SEIS & EIS Advance Assurance?

Her story moves between personal experience and the realities of the legal profession: the moment she was excluded from school at age 11 for refusing to remove her religious head covering; returning to the Bar after the premature birth of her son and discovering that the practice she had spent more than a decade building had suddenly disappeared. It highlights the reality that women entering the profession often still have to work harder to be seen as equal contenders. Her Counsel brings together women whose leadership, perspective, and resilience are helping shape what the legal profession looks like today. At a moment when law is evolving through technological change, new commercial realities, and shifting expectations of leadership, we create space to reflect on the journeys behind that progress. In the conversation that follows, Laurie-Anne reflects more deeply on the experiences that shaped her path to the Bar’s highest ranks. Her story is one of conviction, community, and strategic resilience, and is a reminder that progress in law comes from preparation, credibility, and developing the judgment to know when to push and when to wait.
