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 also frequently acts as incident response manager / breach coordinator for cyber-attacks and other data breaches across Asia, helping clients investigate, manage and mitigate the harmful effects to their businesses, and advising on data protection regimes and reporting obligations across Asia. He also helps clients across the globe recover sums transferred as a result of cyber and other frauds.

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