In the same year he was appointed chamberlain of North Wales, his business being to collect and disburse royal revenues in that newly conquered country.
There he remained, engaging in the war of Leinster and collecting the revenues of the diocese until November 1296, when he was ordered to restore the temporalities to the pope's nominee, William de Hotham.
On 23 September 1299 Richard was appointed baron of the exchequer in the room of John de Insula; in the winter and following spring he was employed on the border with power to fine all who disobeyed the orders of the king's lieutenant, and to victual any castles that might be captured from the Scots.
In January 1306 he was cited to appear before the pope for unlawfully retaining the latter stall, but in April 1309 he was granted a papal dispensation to hold that with his other church preferments.
During the hearing at the Bristol guildhall a popular tumult arose, many were killed, and Richard was for a time kept a prisoner by William Randall and other citizens.
