In 1511 he accompanied his father on the western circuit as clerk to the
assize, and he held this position until 1528. In addition to his father's lands in
Wiltshire and
Oxfordshire he inherited in 1523 the Cambridge estates of his cousin, Thomas Fynderne. His title was disputed, but
Cardinal Wolsey decided in his favour, and also made him clerk of the
Privy Council. Elyot, in a letter addressed to
Thomas Cromwell, says that he never received the emoluments of this office, while the empty honour of
knighthood conferred on him when he was displaced in 1530 merely put him to further expense. In that year he sat on the commission appointed to inquire into the
Cambridgeshire estates of his former patron, Wolsey. He was appointed
High Sheriff of Oxfordshire and
Berkshire in 1527. In 1531 he received instructions to proceed to the court of
Charles V, Holy Roman Emperor, to try to persuade him to take a more favourable view of Henry's proposed divorce from
Catherine of Aragon, the emperor's aunt. With this was combined another commission, on which one of the king's agents,
Stephen Vaughan, was already engaged. He was, if possible, to apprehend
William Tyndale. Elyot was probably suspected, like Vaughan, of lukewarmness in carrying out the king's wishes, but was nevertheless blamed by
Protestant writers. As ambassador Elyot had been involved in ruinous expense, and on his return he wrote unsuccessfully to Cromwell begging to be excused, on the grounds of his poverty, from serving as
High Sheriff of Cambridgeshire and Huntingdonshire for 1532. He was one of the commissioners in the inquiry instituted by Cromwell prior to the suppression of the
monasteries but he did not obtain any share of the spoils. There is little doubt that his known friendship for More militated against his chances of success, for in a letter addressed to Cromwell he admitted his friendship for More, but protested that he rated higher his duty to the king.
William Roper, in his
Life of More, says that Elyot was on a second embassy to Charles V in the winter of 1535–1536 and received the news of More's execution while at
Naples. He had been kept in the dark by his own government, but heard the news from the emperor, or so Roper says, writing years later, but
R. W. Chambers writes that Roper had confused the timing of Elyot's ambassadorship, and of the emperor's remarks—about More's resignation, not his execution. The story of an earlier embassy to
Rome (1532), mentioned by Burnet, rests on a late endorsement of instructions dated from that year, which cannot be regarded as authoritative. From 1539 to 1542 he represented the borough of
Cambridge in
parliament. He had purchased from Cromwell the manor of
Carleton in Cambridgeshire, where he died. ==Private life==
