Mishcon de Reya has hired Sam Millar as a partner in its Disputes department, the firm said on Monday, making him its 13th lateral partner hire of the calendar year.
Millar has more than 25 years’ experience as a disputes and investigations lawyer, in private practice and in-house.
The firm said he has advised companies in financial services, retail, sport, commercial property and construction, and industrials on regulatory investigations and commercial disputes.
Hugo Plowman, chair of the Dispute Resolution department, said Millar brings “extensive expertise in commercial disputes, arbitration and investigations”.
Plowman added: “His appointment builds on a series of recent partner appointments to our Disputes team across London, Hong Kong and the UAE.”
Millar said he was joining “a firm renowned as a disputes powerhouse and for its market-leading expertise”.
He said he looked forward to helping clients navigate complex disputes and to contributing to the continued growth of the firm’s disputes practice.
Mishcon named several recent dispute resolution additions alongside Millar: Robert Rhoda in London, Charlotte Bijlani and Bushra Ahmed in the UAE, Private Wealth Disputes litigator Elliott Phillips, and Of Counsel Mandy Xu in Hong Kong.
Rhoda was the firm’s eighth partner hire of the calendar year. Before joining Mishcon he led the international arbitration practice of Denton’s Hong Kong. He will be based in London and continue to practise in both London and Hong Kong.
Xu joined as Of Counsel in the Hong Kong office. Managing partner Wei Zhang said she follows “a string of recent appointments to Mishcon’s Hong Kong Disputes and Innovation departments”.
Outside disputes, Miriam Carrión Benítez joined as a partner in the Employment department as the firm’s eleventh partner hire of the calendar year. The firm said she is an equality and human rights barrister with expertise in education law.
Millar joins a practice the firm says comprises more than 350 disputes lawyers, with offices in London, Singapore, Hong Kong, Dubai and Abu Dhabi.
Mishcon said Solomonic data ranks it seventh among claimant-side firms, with 44 claims issued in the first three quarters of 2026.
The same data shows more than 6,800 High Court and Competition Appeal Tribunal claims issued in the first nine months of 2026, an 11% increase on the same period last year.
Solomonic also places the firm in the top ten most active firms across all claims, acting in 73 of the disputes issued in that period.
The firm announced Millar’s move on its website without giving a start date or his previous firm.
