Katherine is a well-regarded and popular Senior Junior, recognised in the legal directories for being a “very effective tenacious advocate” with a “razor-sharp brain”. She is a barrister who “gets the results”.

Katherine is ranked as a leading barrister in the field of matrimonial finance and is regularly led by KCs or instructed alone against them. She is noted for her handling of cases that are often high-profile and reputationally sensitive and which engage issues of valuation, tax, non-disclosure, offshore trust structures, and the status of agreements. Katherine is recognised as a “go-to for complicated cases with an international element”, particularly those cases involving issues of jurisdiction and forum non conveniens. She has been instructed as an expert witness on English law in South Africa and provided advice and/or representation in the Cayman Islands, the BVI, the UAE, and Gibraltar.

In every case, Katherine’s focus is aimed at achieving an early favourable settlement, the details of which are formalised efficiently and discreetly. Her cases which are resolved by contested hearing feature regularly in the law reports and address issues across the full matrimonial finance spectrum, ranging from the treatment of non-matrimonial assets (WX v HX [2021] EWFC 14, in which Katherine was the only junior instructed in a case involving four silks), to Part III proceedings brought in this country subsequent to a foreign divorce (AG v VD [2021] EWFC 9).

Katherine is a trained mediator and sits as an early neutral evaluator, most frequently as a private FDR Judge, where she brings to bear her “fantastic” and “user-friendly” manner to help parties reach an agreement without further costly litigation.
