Oentoeng Suria & Partners (OSP), Ashurst’s association firm in Indonesia, has hired litigator Hillman Sembiring as a partner in Jakarta.

Sembiring joins from Hillman Sembiring Advocates, a firm he founded in March 2016. He previously worked at HHP, Baker McKenzie’s member firm in Indonesia.

With expertise in formulating dispute strategies, Sembiring’s experience spans class-action cases, civil lawsuits, financial derivative cases, arbitrations, and import-export disputes. He also conducts internal investigations in clients' companies, especially on corruption and bribery issues.

His arrival means that OSP now has five partners. The firm recently lost disputes lawyer Prawidha Murti to Hiswara Bunjamin & Tandjung, Herbert Smith Freehills’ Indonesia association firm.
