Sir Frederick Madden in his "Remarks on the Monument of Sir Richard Lyster in Saint Michael"s Church Southampton," describes both the judge"s grandfather, Thomas, and his father, John, as of Wakefield in Yorkshire. His mother was a daughter of Beaumont of Whitley in the same county.
He had his legal training in the Middle Temple, where he arrived at the dignity of reader in Lent, 1516, and of double-reader in Lent, 1522, and he was appointed treasurer of the society in the following year. Of his early professional employment there is no account, the year books and other reports entirely omitting his name. But that he had acquired considerable legal eminence may be concluded from his being placed in the office of solicitor-general on 8 July 1521.
He was succeeded in this post by Christopher Hales on 14 August 1525.
And although he is not introduced into the list of attorneys general in Dugdale"s Chronica Series, there is little doubt that he then followed Ralph Swillington in that office. As he is mentioned with the title in the will of Cicily Marchioness of Dorset, dated 6 May 1527.
And as Christopher Hales was made attorney-general immediately after Lyster"s elevation to the bench as chief baron of the Exchequer on 12 May 1529, apparently as his successor. On his promotion he was knighted and was named as a commissioner on the trials both of Bishop Fisher and Sir Thomas More.
But he does not appear to have taken any prominent part in either.
After presiding in the Exchequer above sixteen years, he was advanced to the office of chief justice of the King"s Bench on 9 November 1545. And in this character he attested the submission and confession of Thomas Duke of Norfolk on 12 January 1547, a fortnight before the king"s death. On the accession of Edward VI he was reappointed, and his first duty on the Thursday after was to address a batch of new serjeants on their inauguration at Lincoln"s Inn.
This he did, as the reporter significantly says, in "a godly thowghe sumwhate prolix and long declaration of their duties and exhortation to their full following and execution of the same." He resigned at the end of the first five years of the reign on 21 March 1552, when he was succeeded by Sir Roger Cholmeley.
The remainder of his life he spent at his mansion in Southampton, which John Leland describes as being "very fair". And dying on 14 March 1554, where he was buried in Saint Michael"s Church.
