Chambers and Partners 2022 and Legal 500 2023


Lily’s practice covers all aspects of private family law, especially the financial and international aspects.

She was named Family Law Junior Barrister of the Year at the Chambers and Partners UK Bar Awards 2023 and was runner-up in the category of International Family Lawyer of the Year at the LexisNexis Family Law Awards 2023.

She is ranked in Band 1 for matrimonial finance in Chambers and Partners 2023 in which she is described as “very eloquent, meticulous and someone with a really bright future".

The 2022 edition of Chambers and Partners describes her as "a bright, determined, thorough cross-examiner who is well informed about the strengths and weaknesses of her case” and who "gets on top of obscure areas of law quickly” and “has the ability to think on her feet”.

The 2021 edition says she is “quick on the uptake, numerate and has good client management skills, proving kind but firm” and that "she provides comprehensive, well-reasoned advice and insight into the French divorce processes."

As a former investment banker in the UK M&A team at Merrill lynch, Lily brings a commercial edge to her financial cases and as a fluent French speaker owing to her formative years at the French Lycée, Lily is adept in cases with an Anglo-French element.

Previous editions of Chambers and Partners say that she is “hard-working, presents well and is an effective advocate”, that “she is very dynamic in her approach to cases and very personable with clients", that her advocacy is “very precise” and that she is considered to be “very tenacious” and is someone who “isn’t frightened of anyone”.

In 2019 she was shortlisted UK Family Law Junior Barrister of the year by Chambers and Partners and in 2018, UK Family Law Junior Barrister by LexisNexis.

As the author of the chapter on declarations of marital status and co-author of the chapter on the English court’s approach to the recognition of overseas divorces in the latest edition of the leading family law textbook, Rayden and Jackson, Lily is recognised for her additional expertise in matters concerning marital status.

Lily is also regularly instructed in cases involving fine art collections due to her in-depth knowledge of the international art market. She completed the Diploma of Art Profession Law and Ethics at the Institute of Art and Law with Distinction.
