Indonesia officially became 94th member of Hague Conference on Private International Law (“HCCH”) upon depositing its instrument of acceptance of the HCCH Statute on 11 August 2026. This accession marks a significant milestone, following Indonesia’s formal application for membership on 4 December 2025. Joining the HCCH’s global network opens a new chapter in Indonesia’s private international law landscape, strengthening its role in shaping cross-border legal cooperation.
Established in 1893, HCCH is the world’s leading intergovernmental organization dedicated to the unification of private international law across diverse jurisdictions and legal systems. It develops and administers multilateral conventions and other instruments that harmonize rules governing cross-border civil and commercial matters, from the recognition of judgments to the service of documents abroad and the authentication of public documents. With Indonesia’s accession, the HCCH’s membership now stands at ninety-three (93) states and one regional economic organization, the European Union.
The Benefit
HCCH membership affords Indonesia the opportunity to actively negotiate and shape the rules of private international law. As a Member, Indonesia gains a voting seat in the organization’s governance and a direct role in the development of future conventions, enhancing its capacity to advance national interests in international trade, investment, and economic cooperation. This marks a shift toward a more prominent role within the global community, enabling Indonesia to participate in crafting private international law instruments rather than merely adopting those negotiated by others.
Prior to attaining full membership, Indonesia had already gained practical experience with an HCCH instrument through its adoption of the 1961 Apostille Convention. The convention entered into force for Indonesia on 4 June 2022, replacing the often lengthy and costly consular legalization process with a single authentication issued by a designated authority. This reform has significantly streamlined the use of both inbound and outbound public documents in Indonesia, facilitating matters such as company registration, banking, and cross-border litigation.
The 1965 Service Convention is another key HCCH instrument that Indonesia is currently considering for accession. Its adoption is expected to establish a uniform and reliable channel of transmission through designated central authorities, thereby reducing delays and uncertainty in the service of judicial documents to and from Indonesia. This would replace the long-standing reliance on a complex and time-consuming diplomatic or consular channels, offering greater efficiency and legal certainty in cross-border proceedings.
Homework
Indonesia’s accession to HCCH membership coincides with the ongoing development of domestic private international law, most notably the pending Bill on Private International Law (Rancangan Undang-Undang Hukum Perdata Internasional). The bill has been placed on the 2026 National Legislation Program Priority List. Once enacted, it will establish national rules on private international law whose provisions span multiple legal domains intersecting with cross‑border matters, including family law, inheritance, trade, jurisdiction, and the recognition and enforcement of foreign judgments. This future legislation is expected to provide a coherent framework that complements and operates in tandem with Indonesia’s HCCH commitments.
HCCH membership represents a milestone that must be translated into tangible benefits through the synchronization of national law, most immediately, the enactment of the Private International Law Bill, to be followed by reforms of the Civil Code and civil procedural laws. In practice, this entails greater clarity and modernization of rules governing jurisdictional issues and choice of law, aligned with international practice, so that mechanisms for cross‑border service, evidence‑taking, and enforcement can operate effectively in conjunction with HCCH instruments.
Sector‑specific alignment must likewise not be overlooked. Areas of law with significant cross‑border dimensions such as shipping and maritime will require their regulatory frameworks to be reviewed and, where necessary, updated to ensure consistency with the private international law rules brought into sharper focus by HCCH membership.
In short, Indonesia’s admission as the 94th Member of the HCCH marks an important first step. Its true value for national interests, including economic development and the protection of business entities and citizens, will ultimately depend on legislative and regulatory follow-through. Only by translating this new international standing into a coherent and modernized domestic legal framework for cross-border transactions and disputes, the benefits of HCCH membership can be fully realized.
