Stephanie Balsys


Personal Profile

Stephanie is a Partner in the Private Commercial Litigation Team, advising UHNW clients and corporates in international commercial disputes.

The cases she advises on are typically multi-party, multi-jurisdictional disputes arising out of the breakdown in shareholder and investor relationships, joint ventures or family business arrangements. They frequently involve allegations of fraud, conspiracy or deceit and concurrent criminal proceedings, and defending or procuring asset freezing orders and disclosure orders. As such she works closely with foreign counsel and technical experts, including regarding asset tracing, seizure and enforcement issues. Stephanie has acted on several of the most substantial civil litigation proceedings before the High Court in recent years. She regularly coordinates large teams and manages complex and cross-border disclosure processes. She has notable experience of advising clients in disputes subject to arbitration under the LCIA, ICC and UNCITRAL Rules.

Stephanie is particularly experienced in disputes involving parties from or with interests in Central Europe and the CIS. She has travelled extensively in those regions and is a regular speaker at conferences on issues of English law and arbitration relevant to local practitioners. 

Before joining Mishcon de Reya in 2018, Stephanie trained at a leading global litigation firm, including spending time seconded overseas and to the EMEA litigation team of a London-based investment bank.

Stephanie is the Secretary and an Executive Committee member of the RCAN Arbitration Network, and chairs the British-Kazakh Society Law Group.
