The younger son of a minor Essex farmer, Courtman made his way at first in the lower reaches of the legal profession, but prospered sufficiently to secure admission to Lincoln’s Inn in his mid-twenties. In 1603 he witnessed the will of Sir Jerome Weston, a prominent Essex gentleman, in which he was asked to assess what Weston’s son-in-law, Sir Edward Pinchon, owed the estate.
Courtman probably owed his election at Midhurst in 1614 to Sir Jerome Weston’s son Sir Richard, who had been returned there in 1604 and was closely connected with the lord of the borough, Anthony Browne, 2nd Viscount Montagu. He made no recorded speeches but was among those appointed on 13 Apr. to draft the address against undertakers, and, on 25 May, to consider the bill enabling the lands of Sir Robert Wroth II* to be sold for payment of debts. As a lawyer he was entitled to attend the committee for the repeal and continuance of expiring statutes, and he was one of those deputed to examine the notes delivered into the House by Ferdinando Pulton, the legal writer engaged on publishing a comprehensive edition of English statutes.
In the aftermath of the dissolution, Courtman was among the ‘men not overwrought with practice, and yet learned and diligent, and conversant in reports and records’, whom Sir Francis Bacon* recommended to the king ‘to restore the ancient use of [law] reporters’. However, nothing seems to have come of this proposal.
