615 of June 6, 1837, remained in effect as the governing laws for the division until they were gradually replaced by new legislative enactments.

The region was formally restructured as the Chota Nagpur Division, with Ranchi as its headquarters and Hazaribagh, Chaibasa, and Purulia serving as subordinate district centers.

Additionally, a Subordinate Judge oversaw both Singhbhum and Manbhum, while a Munsif handled cases for Purulia.
