Personal Profile

Harriet is an Associate in the Family Department and advises on all aspects of family law. She has a depth of experience of contentious and non-contentious family law work and specialises in both the financial consequences of marital and relationship breakdown, and children matters including surrogacy and donor agreements.

Harriet has worked on cases requiring complex valuations of businesses and has experience of trusts in family proceedings. She has also dealt with high-net worth cases where existing pre-nuptial agreements have been challenged. In respect of children work, she is accustomed to high conflict cases and cases involving domestic abuse and coercive control (including where the Local Authority has been asked to report on welfare issues) as well as relocation (international and domestic). Before qualification, she spent two years working for barristers in Paris specialising in Financial Crime.

Harriet regularly contributes to legal journals such as the Family Law Journal. She is a member of Resolution, an organisation which campaigns for improvements to family justice and recently was part of a panel addressing the YRes National Conference on new developments in Surrogacy and Modern Families law. In 2024 she co-authored a chapter of the Resolution Handbook examining international considerations on spousal maintenance.

Harriet graduated from the University of Cambridge and qualified as a solicitor in March 2019. She joined Mishcon de Reya in 2024.
