The other three counties were overseen by a Justiciar of North Wales and a provincial exchequer at Caernarfon, run by the Chamberlain of North Wales, who accounted to the Exchequer at Westminster for the revenues he collected. Under them were royal officials such as sheriffs, coroners, and bailiffs to collect taxes and administer justice. The king had ordered an inquiry into the rents and other dues to which the princes had been entitled, and these were enforced by the new officials. At the local level, commotes became hundreds, but their customs, boundaries and offices remained largely unchanged.
