Professional Practice

Following a decade in which Peter appeared in the Supreme Court twice (in Agbaje and Sharland) and in the Court of Appeal in a number of other leading cases (including Prest, Brack and Hart), Peter took Silk in 2020. He continues his high-profile appellate work, most recently leading the wife’s legal team in her successful and ground-breaking outing to the Court of Appeal in the latest stage of the decade-long Goddard-Watts litigation.

Peter specialises in all aspects of the law relating to relationship finance, with his work encompassing matrimonial finance and claims for financial provision for children, with an emphasis on complex financial cases involving substantial assets, trust structures, tax and valuation issues and/or requiring injunctive relief and/or third party disclosure; international jurisdictional disputes; and the drafting and enforcement of pre-nuptial, post-nuptial and cohabitation agreements. He has particular expertise in the law on setting aside orders for non-disclosure (the subject matter of Sharland and Goddard-Watts) and on proceedings for contempt of court (at issue in Prest and Hart).

Peter prides himself on providing top-quality client care. He considers it essential that his clients are given the information and time to understand the advice he is giving and that he is available throughout proceedings to assist, if called upon to do so. He is ranked as a leader in his field in Chambers & Partners, Legal 500 and Spears 500. The 2022 volume of Legal 500 records that “Peter is the most charming intellect in the business. He is a wonderful advocate who makes every client feel special and in the right hands.” Whilst the 2023 volume of Chambers & Partners describes him as “a fantastic person to pick up the phone to and run issues by. He’s personable, charismatic, and excellent. He’s a nice man with a great intellect who delivers results” and as having “a quick brain and an easy rapport with clients”.

Peter has utilised his standing in the profession and rapport with clients to develop a busy additional practice as a Private FDR evaluator and has an enviable reputation for promoting settlement, even in the most contentious of cases.
