Hague Conventions

Also known as: Hague Conference, HCCH Conventions

Quick answer

The Hague Conference on Private International Law (HCCH) develops treaties that help legal systems cooperate across borders. Its conventions cover subjects including public-document authentication, child abduction, intercountry adoption and service of legal documents.

Each Hague Convention is a separate treaty with its own scope, parties and conditions. Check the HCCH status table for the particular instrument rather than assuming that membership of the organisation makes every convention applicable.

The 1961 Apostille Convention concerns public-document authentication. The 1980 Child Abduction Convention provides a process for the prompt return of children wrongfully removed or retained across borders; a return decision does not decide custody. Its six-week provision allows reasons for delay to be requested if no decision has been reached, rather than guaranteeing return within that period.

The 1993 Adoption Convention establishes safeguards and cooperation for intercountry adoption.
