Katie is a Senior Associate in the family team at Boodle Hatfield. She advises clients on all aspects of family law, with a particular emphasis on high net worth financial remedy proceedings on divorce. A high proportion of her workload involves complex wealth structures both in the UK and abroad and a number of her client's cases are dealt with in the High Court as a consequence. She has over the last year been involved in several sets of financial remedy proceedings where the majority of the parties' wealth is tied up in a family business and the primary issue has been the value of the company and the ways in which funds can be extracted from it to buy out one spouse's interest. She has a varied client base with backgrounds in private equity, sport, retail and technology.

Katie's practice also encompasses the preparation and negotiation of pre- and post-nuptial agreements in order to seek to protect certain assets in the event of a divorce. Such agreements may also be preceded by cohabitation agreements for unmarried partners as a means of regulating each partner's financial contribution to their relationship.

Katie has expertise in private children law matters which often involve disputes regarding the arrangements for the children upon their parents' separation, applications by one parent to relocate a child elsewhere in the UK or abroad and financial provision for children of unmarried parents.

Clients and Counsel commend her support throughout what can be a difficult process and her detailed knowledge of the law.

Katie's recent projects

  • Acting for Mr Don Gallagher, a male civil partner in the case of Lawrence v Gallagher [2012] EWCA Civ 394 which was the first civil partnership financial relief case to reach the High Court and subsequently the Court of Appeal. The case was widely reported in the media, being the first of its kind.
  • Advising a father in relation to his ex-wife's application to relocate their two children abroad with her and her new partner as a result of her partner's new employment.Advising a wealthy Middle Eastern family in connection with the preparation of pre and post-nuptial agreements for the heirs as part of a wealth protection strategy in order to preserve it for future generations. The family lead a highly international lifestyle which resulted in the need to work closely with lawyers in various jurisdictions.
  • Acting for an international sport star in connection his divorce proceedings with his wife, a renowned model.
  • Acting for the wife in the case of WM v HM [2017] EWFC 25. The primary issue in the case related to the value and extraction of liquidity from the parties' family business in order to meet the wife's award. The husband also attempted unsuccessfully to argue that he had made a special contribution to the marriage which should justify a departure from equality.
  • Acting for the husband in the case of B v B [2013] EWHC 1232 (Fam) in a two week trial in the High Court. The family had liquid wealth of £40m and the husband had potential illiquid wealth of, on the wife's case, between €139m to €278m as a result of the husband's fund manager role at a private equity firm. The main issue in the case was the extent to which the wife should be entitled to share in these valuable illiquid assets in the future. Katie and the team successfully argued on behalf of the husband that there should be a substantial departure from equality in relation to the illiquid assets given the post-separation efforts required by the husband to bring the funds to fruition.
  • Acting for the former husband in relation to his former wife's claim for further maintenance provision for their disabled child, who is now in her 20s but still lives with her mother and her mother's new husband.
