Susan Apthorp
Spear’s Review
Keystone Law’s Susan Apthorp is praised by clients and colleagues alike for her around-the-clock work ethic and dedication to the job. In the words of one industry commentator, a senior family lawyer: ‘If you work with her, you have to step up your game.’
Apthorp has extensive experience and a record of litigating at the highest levels. She is known for both HNW and UHNW divorces, and a significant part of her thriving practice involves cases with an international element and children with complex medical needs. Apthorp has a special interest in supporting families with disabilities and in protecting women who have experienced abuse in a relationship.
Prior to her move to Keystone in 2020, the straight-talking Apthorp spent more than a decade as a partner at Sears Tooth, another of London’s most formidable family practices.
