Debby is a partner in our Dispute Resolution practice. Debby's practice is focussed on complex high-value disputes. Debby also has particular expertise in restructuring, work-outs and corporate insolvency, having acted for international clients in a number of high-profile bankruptcy and restructuring cases in Indonesia. Debby was trained with Hiswara, Bunjamin & Tandjung and the London office of its associated firm, Herbert Smith Freehills, in her early years of practice; and as a result, Debby has extensive first-hand experience in representing and handling transnational and complex commercial disputes before the Indonesian courts, as well as in domestic and international arbitrations. Debby does not only advise clients on contentious matters but also provides strategic advice and dispute avoidance tactics, given her distressed market experience. Debby practised as a partner in two other reputable firms with international tie-ups before returning to Hiswara, Bunjamin & Tandjung in August 2017.
