Emma Harte

Spear’s Review

Keystone Law partner Emma Harte is widely regarded as one of the UK’s top family law mediators. Her clients are predominantly international UHNWs who seek to resolve matters outside of the courtroom, and Harte is equipped to advise on divorce and separation, financial disputes, pre- and postnuptial agreements and child arrangements. Often, leading City firms refer their clients to her.

‘I adopt a robust and pragmatic approach, which leads to successful and fair outcomes in my cases,’ she tells Spear’s.

Harte is no stranger to complex financial structures; one prenuptial agreement she worked on involved $15 billion in assets across six jurisdictions

She is a fellow of the International Academy of Family Lawyers, a member of Resolution and an accredited member of the Family Mediation Council. In 2025, she was shortlisted for Family Lawyer of the Year at the Spear’s Awards.
