Jonathan Crompton

Jonathan Crompton helps companies and individuals navigate complex cross-border disputes and investigations involving their Asian business, specialising in particular in financial services and technology related disputes and cyber incidents.

Jonathan advises on all forms of disputes including litigation before national courts and arbitral tribunals operating under various rules (in particular, HKIAC, ICC and UNCITRAL), and on investigations by regulators (notably financial services regulators such as the Securities and Futures Commission). His clients include senior individuals, asset managers, and leading multi-national corporations and brands. As a result of RPC's predominantly 'conflict free' model for financial services disputes, Jonathan represents senior individuals and companies in claims brought by or against leading banks where other firms are unable to act. 

As Asia lead for RPC's 'ReSecure' 24/7 cyber incident response service, Jonathan frequently acts as incident response manager / breach coordinator and legal advisor for cyber-attacks and other data breaches across APAC. He helps clients investigate, manage and mitigate the harmful effects to their businesses of cyber incidents, in addition to advising on the legal and regulatory consequences of the incidents. Jonathan also represents clients across the globe in cyber-related litigation, including defending customer claims for losses arising from a breach, and helping to recover sums lost as a result of cyber, crypto and other frauds.

Recognised for his work in both Disputes and Technology, Media and Telecommunications, in 2023 Jonathan was included in the Legal 500's Arbitration Practice Powerlist - Hong Kong, shortlisted for Dispute Resolution Lawyer of the Year in the ALB Hong Kong Law Awards, and one of two individuals awarded a Distinguished Community Service Individual Award by the Law Society of Hong Kong.

Jonathan has practiced in London, Hong Kong and Thailand and speaks English, French and conversational Swedish.
