The Ḥuqúqu'lláh payment is considered a way to purify one's possessions. It is an individual obligation; nobody in the general community should know who has or has not contributed, nor should anyone be solicited individually for funds. Along with several other practices, it was initially only applicable to Baháʼís of the Middle East until 1992, when the authoritative English translation of the "Kitáb-i-Aqdas" was published and the Universal House of Justice made Ḥuqúqu'lláh universally applicable. A central office to receive payments was established at the Baháʼí World Centre in 1991, and payments are made to trustees appointed by the Universal House of Justice in every country or region.
