Sarah Jane Boon

Spear’s Review

Charles Russell Speechlys partner Sarah Jane Boon advises across the full spectrum of family law, including high-value financial claims arising from divorce, cases involving cryptocurrency, applications to the English court following an overseas divorce, and private children law matters. She also has a growing practice in nuptial and cohabitation agreements.

She regularly works on the most complex and challenging cases at her firm and is praised by clients and counsel alike for her sound advice and attention to detail. Boon says she understands that divorce and separation can often feel ‘overwhelming’ for clients, and she therefore focuses on explaining things clearly and managing expectations. 

‘I will tell people things that perhaps they don’t necessarily want to hear,’ she tells Spear’s. ‘It’s better to rip the band-aid off and tell them from the outset than to give somebody an unreasonable view about what the outcome is likely to be.’
