Richard Chaterley first appears in the records in June 1439 when he was commissioned to investigate wastes committed in the property of the hospital of St. Nicholas in Richmond. This is not evidence that he was a Yorkshireman: it is rather the first indication of his association with another member of this commission, William Ayscogh (d.c.1455), promoted to the bench of the common pleas in the following year and a patron of both the hospital and our MP. Ayscogh’s petition to the chancellor had provoked the issue of the commission and Chaterley had acted as one of the pledges for the petition’s prosecution.
By the time Chaterley purchased this property in Derby he was already established as a lawyer of some local significance. On 20 June 1441 he was named as the associate to the assize justices on the Midland circuit, an appointment he presumably owed to Ayscogh, who was then serving on that circuit. He was active in the role, sitting, for example, with Ayscogh at gaol deliveries held at Leicester and Nottingham in 1445 and with the other assize justice, John Portington, at the Warwick assizes of July 1447.
Since Chaterley’s clerkship meant that he spent much time at Westminster – he is occasionally styled ‘of London, gentleman’ in the records – he was a natural choice to represent Derby in Parliament, and, on 29 Oct. 1449, the townsmen duly elected him to sit with his putative brother, Thomas, a yeoman of the Crown. During the last session of this Parliament he was named along with the two Nottinghamshire MPs, John Stanhope* and Henry Boson*, to inquire in four Midland counties into concealments of deodands and the chattels of suicides, earlier assigned to the royal almoner to be applied in alms. At the next Derby election in 1450 he offered surety for Agard, a servant of Walter Blount*.
Chaterley continued to act in concert with the Midland assize justices, receiving his last commission as their associate in July 1458.
