Within a few weeks of attaining his majority in 1604 Fanshawe was granted the reversion to the duchy of Lancaster post held by his brother,
...the chancellor, in his younger days, of good service; now in his age abused by bad servants ... These letters written by one [Loveday] that will sell his master and all for 20s. ... the chancellor [is] free [of blame], save only for setting his hand to that which Loveday brought him ... who had undertaken for money to have put in divers names not returned.
CJ, i. 478a; Procs. 1614 (Commons), 187-8.
Fanshawe was appointed to three committees concerning bills for parish taxation (7 May), the prevention of abuses in his brother’s office in the King’s Bench (18 May) and the motion of Edward Alford* to ‘consider of some course concerning the old debts’ (31 May).
In 1617 Fanshawe accompanied Parry’s successor, (Sir) John Dackombe*, on a visit to Lancashire to enfranchise copyhold tenants of the duchy. He made some useful acquaintances in the Clitheroe area, including the meeting’s host, Sir Ralph Assheton of Whalley.
In 1626 Fanshawe failed to obtain his accustomed seat at Clitheroe. Instead an unnaturalized Scottish courtier, George Kirke, was returned, apparently on the duchy interest. Fanshawe’s brother Thomas I raised objection in the Commons, but when a new writ was procured the seat was taken by the Fanshawes’ nephew, Christopher Hatton.
Fanshawe’s parliamentary experience had not taught him discretion, for in 1634 he was accused of describing his neighbour, the former Speaker (Sir) Thomas Richardson, as ‘a great blabber-lipped fellow, fitter to have made a bearward than a chief judge’.
