Harriet Gibson


Hattie is a member of Russells’ Family & Matrimonial Department. She trained at the top-ranked firm Penningtons Manches Cooper.

She works across both financial and private children disputes, including multi-jurisdictional and high net worth cases. At Penningtons, she was part of the team acting for the Aire Centre in the case of R. (on the application of TT) v Registrar General for England and Wales, a complex judicial review case about the wish of a parent to be registered on the birth certificate of their child as their reassigned gender, rather than their original gender.

Hattie also has experience in obtaining parental orders in surrogacy cases and obtaining emergency remedies for clients, both against perpetrators of domestic violence and against the press to prevent publication, having initially practised as a privacy lawyer.

Prior to her legal training, she was a choral scholar of Cambridge University, where she graduated with a Classics degree in 2012. She spent two years in Paris working for Counsel instructed to defend a global company accused of bribery and corruption, and subsequently joined the IP and Commercial department of a London law firm. She is co-author of the article “lessons in undue influence” published in the New Law Journal and has written a practice note on the definition of children in legal documents, published on Lexis PSL.
