🇮🇩 The Dynamics of Indonesian Commercial Law
-
The Local-Global Model (Foreign Law Firms): Foreign law firms (FLFs) are generally restricted from practicing Indonesian law directly. To serve international clients, global firms like Baker McKenzie, A&O Shearman, and Herbert Smith Freehills form formal associations with licensed local Indonesian law offices (like HHP, Ginting & Reksodiputro, and HBT). This model allows the local firm to advise on Indonesian law while the global partner handles the cross-border and international aspects of a deal.
-
M&A and Capital Markets Dominance: Firms like Assegaf Hamzah & Partners and those associated with global firms consistently lead the league tables for complex M&A and high-value Capital Markets transactions (IPOs and securities).
-
Infrastructure and Natural Resources: Given Indonesia’s vast geography and resources, expertise in Energy, Natural Resources, and Infrastructure/Project Finance is essential. Firms like SSEK and ABNR have long-standing reputations in these complex, highly regulated sectors.
-
The Rise of Independents: Firms like SSEK and Makarim & Taira S. have maintained a strong presence as leading independent commercial firms, highly valued for their local market knowledge and ability to handle both transactional and contentious matters.
These top law firms in Jakarta are the critical partners for any business navigating the intricacies of Indonesia’s rapidly growing and developing regulatory and commercial landscape.
