A kudurru or boundary stone from Sippar (pictured),[i 1] in southern Iraq, records a legal settlement, in his 25th year, of a feud over an estate in the district of the city of Sha-mamitu.

To complicate things, Arad-Sibitti had inadvertently killed Buruša’s slave with an arrow during the earlier reign of Ninurta-kudurri-uṣur I, c. 983–981 BC.

[2] A recently identified kudurru from the east of the Tigris in the Diyala region on the Mingatu-karītu canal is dated to his 16th year and details the sales of two plots of land.

[4] A single unpublished economic text in the Musée d'Art et d'Histoire, Geneva, Switzerland, is dated to his reign.
