Convention on Reduction of Statelessness

The 1961 Convention on the Reduction of Statelessness is the principal universal treaty aimed at preventing and reducing statelessness. Adopted in New York on 30 August 1961, it entered into force on 13 December 1975 and is administered, in practice, by the UN High Commissioner for Refugees (UNHCR), which the UN General Assembly designated as the body to assist statelessness cases under Article 11.

The Convention establishes safeguards against statelessness at four key moments:

• At birth: Article 1 requires contracting states to grant nationality to persons born on their territory who would otherwise be stateless, either automatically or upon application.
• Through descent: Article 4 obliges states to grant nationality to a person born abroad to one of their nationals if that person would otherwise be stateless.
• On loss, renunciation, or deprivation: Articles 5–8 prohibit loss or deprivation of nationality where it would render a person stateless, with narrow exceptions (e.g., nationality obtained by fraud).
• On state succession: Article 10 requires that treaties governing territorial transfers include provisions to prevent statelessness.

The treaty complements the earlier 1954 Convention relating to the Status of Stateless Persons, which defines a "stateless person" and sets out their rights, while the 1961 instrument focuses on prevention. Together they form the core international legal framework on statelessness.

Accession has historically been slow but accelerated after UNHCR launched the #IBelong Campaign in 2014, which set a ten-year goal to end statelessness. By the campaign's close, parties numbered in the high seventies, still far short of universal ratification. Major states including the United States, India, and most Gulf countries remain outside the regime.

The Convention permits limited reservations and contains no individual complaints mechanism; implementation depends on domestic nationality laws. It is frequently invoked in advocacy concerning the Rohingya, Bidoon, and stateless children of mixed-nationality parents in jurisdictions that bar maternal transmission of citizenship.
