Catherine Costley

My clients are high-net-worth families whose financial affairs involve complexities such as offshore structuring, trusts, and complex corporate structures. I am very familiar with the financial affairs of those working in banking, private equity, finance, or law, but also entrepreneurs, sportsmen and women, actors/writers, and creatives.

Alongside the financial complexities, my clients’ relationships often feature relationship dynamics (for example, personality disorders, control, abuse, and dependency), which I am skilled at navigating with them. After lawyers step away, I focus on my clients’ lives: their financial security, co-parenting, or independence.

I am listed in the Top 23 Divorce Lawyers on Midult.com’s directory, where I am described as “serenity itself, methodical, thoughtful and kind” but also “progressive” and “fierce”. In Tatler magazine, I am described as “pin sharp”. I am recommended in Spear’s Family Law Index 2024. In 2023, I appeared in Spear’s magazine’s feature on “Modern Family” as part of “a new generation of family lawyers whose stars are in the ascendant or at the apogee of their profession”.

Outside of law, I competed in endurance events (Ironman Vichy and Austria, Ironman 70.3 World Championships in Florida). However, in recent years, I have switched to the other well-known endurance sport of parenting two young boys.
