The Kitáb-i-Aqdas - The Most Holy Book
Index term: treasury, under House(s) of Justice
n42.
the House of Justice
In referring to the House of Justice in the Kitáb-i-Aqdas, Bahá'u'lláh does not always explicitly distinguish between the Universal House of Justice and the Local House of Justice, both of which institutions are ordained in that Book. He usually refers simply to "the House of Justice", leaving open for later clarification the level or levels of the whole institution to which each law would apply.
In a Tablet enumerating the revenues of the local treasury, 'Abdu'l-Bahá includes those inheritances for which there are no heirs, thus indicating that the House of Justice referred to in these passages of the Aqdas relating to inheritance is the local one.
q72.
 
Question: Again a question hath been asked concerning the residence and personal clothing: are these to revert, in the absence of male offspring, to the House of Justice, or are they to be distributed like the rest of the estate?
Answer: Two thirds of the residence and personal clothing pass to the female offspring, and one third to the House of Justice, which God hath made to be the treasury of the people.
