Family law Q&A: Debbie Chism on the benefits of collaborative law

Personal

Away from work, Debbie offers her support as Chair of Governors to an independent school for girls.

Experience

ES v SS [2023] – Debbie acted for the husband in a financial remedies claim (c. £50m+) where the main issues considered by the Court related to valuations of private equity interests and tax risks, as well as departure from equality in the husband’s favour as a result of wealth generated prior to the marriage.

IR v OR [2022] – Debbie acted for the wife, achieving an award of over £70m (exceeding the husband’s offer by over £20m). The case dealt with how wealth generated before the marriage and from the sale of a family business should be treated, as well as the enforceability of a pre-nuptial agreement.

XW v XH [2019] EWCA Civ 549; XW v XH [2019] EWCA Civ 2262, [2020] 4 WLR 22 – Debbie acted for the wife who was awarded one of the highest recorded English divorce settlements by the Court of Appeal. The case dealt with issues of special contribution, privacy and foreign marital contracts. The wife was successful, exceptionally, in her application for the reporting restrictions order granted in the High Court to be maintained in the Court of Appeal.

HRH Prince Louis v HRH Princess Tessy [2017]– Debbie acted for HRH Prince Louis of Luxembourg in the successful application for a reporting restrictions order relating to family proceedings.
