The HCCH (Hague Conference on Private International Law – Conférence de La Haye de droit international privé) is an intergovernmental organisation the mandate of which is “the progressive unification of the rules of private international law” (Art. 1 of the Statute).

In today’s world, individuals and businesses are constantly engaged in cross-border interactions, with work, commerce, study, shopping, travel, relationships and more increasingly taking place across multiple countries. These activities require a high degree of legal certainty and predictability to thrive. However, when taking place across borders the differences between countries’ legal systems often leave gaps in the legal framework, resulting in uncertainty as to which authority has jurisdiction, which law is applicable, how decisions are recognised and enforced and what cooperation mechanisms are available to overcome challenges of cross-border judicial or administrative procedures.

The HCCH’s mission is to resolve these questions by providing internationally agreed solutions, developed through the negotiation, adoption, and operation of international treaties, the HCCH Conventions, to which States may become Contracting Parties, and soft law instruments, which may guide States in developing their own legislative solutions. These Conventions and instruments provide clarity and direction in cross-border relations across three main areas:

  • International Family and Child Protection Law
  • Transnational Litigation and Apostille
  • International Commercial, Digital, and Financial Law

The ultimate goal of the organisation is to work for a world in which, despite the differences between legal systems, persons – individuals as well as companies – can enjoy a high degree of legal security.

Members and Connected Parties

The HCCH is composed of 91 Members – 90 States and the European Union - representing all regions of the globe. In addition, an increasing number of non-Members have either signed or become Contracting Parties to HCCH Conventions. As a result, the work of the HCCH encompasses over 150 countries around the world.

HCCH Members designate “National Organs” to guide, monitor, and promote the work of the Organisation, and Contracting Parties to HCCH Conventions contribute through their Central or Competent Authorities, designated under specific HCCH Conventions.

Post-Convention Activities

The HCCH conducts extensive non-normative work to ensure the effective implementation and practical operation of its Conventions and instruments. To this end, it engages in various post-Convention activities:

  • Organisation and participation in international conferences and seminars, including Special Commissions on the practical operation of the HCCH Conventions;
  • Publication of explanatory reports, guides to good practice and other materials, available here;
  • Maintenance of online databases and platforms (INCADAT, iSupport, e-APP);
  • Provision of trainings and technical assistance.


The origins of the HCCH date back to 1893, when delegates from 13 States convened in The Hague, at the initiative of Tobias Asser, to resolve issues relating to civil procedure and jurisdiction. This was the first “Hague Conference” on private international law, now known as the First Session of the Hague Conference. This session saw the development of the first “Hague Convention”, the Convention on Civil Procedure, which was formally adopted shortly after, in 1894, and signed on 14 November 1896.

In subsequent years, the Hague Conference met several times to negotiate international treaties on a broad range of private international law matters, until, at its Seventh Session in 1951, participating States adopted a Statute which, upon its entry into force in 1955, would establish the HCCH as a permanent intergovernmental organisation.

Since then, the HCCH has held regular plenary sessions, with substantial preparatory work and meetings in between, resulting in the adoption and implementation of over 40 Conventions and instruments.

A respected forum for effective multilateralism, the HCCH brings nations together to cooperate, through a series of regular meetings, in the joint development of mutually beneficial legal frameworks.

The main purpose of Plenary Sessions (or Diplomatic Sessions) is the negotiation and adoption of Conventions and other instruments.

Special Commissions, composed by governmental experts, meet in between Plenary Sessions to prepare draft Conventions to be considered for adoption, as well as to review the practical operation of existing Conventions and recommend improvements in their implementation.

Experts’ Groups are exploratory bodies tasked with conducting research on specific new areas of work, while Working Groups are bodies established to develop concrete solutions in relation to existing or potential future Conventions, such as draft provisions, principles or guides.

Together, the meetings of the Plenary Sessions, Special Commissions, Experts’ Groups, and Working Groups drive forward the work of the HCCH.

Governance and Structure

The HCCH is governed and funded by its Members, which exercise their authority through its two governing bodies:

  • The Council on General Affairs and Policy, which meets annually to review progress and set the work programme of the Organisation.
  • The Council of Diplomatic Representatives, the Organisation’s primary financial and budgetary authority, which meets annually to approve the HCCH’s budget and apportion expenses among Members.

The Permanent Bureau is the organisation’s multinational secretariat. It is responsible for the organisation of Plenary Sessions and other meetings, the conduct of preparatory research, and for supporting the proper operation of the HCCH Conventions, among other tasks. Its headquarters are located in The Hague (Netherlands), with a Regional Office for Latin America and the Caribbean in Buenos Aires (Argentina) and a Regional Office for Asia and the Pacific in Hong Kong (China).
