Hastyng was active by the early 1400s, when he and his first wife pursued a lawsuit in the court of common pleas. The purpose of this action was to recover a debt owed to the late Robert Folsham, probably Margery Hastyng’s previous husband since she sued as his executrix.
In April 1413, the admiral of England (Thomas Beaufort, earl of Dorset) received orders to permit Hastyng and ten other masters of fishing vessels from the port to pass freely out to sea.
In 1417, Hastyng’s fellow burgesses elected him to the first of his four terms as a bailiff of Great Yarmouth. During the second of these terms, he and his fellows presided over the borough’s elections to the Parliaments of 1420 and May 1421. When he himself gained election to the Commons of 1422, his sureties included Geoffrey Pamping, probably a friend as well as a business associate, since Pamping nominated him as an arbitrator in 1424.
It is likely that Hastyng was relatively elderly when he began his final term as a bailiff of Yarmouth in the autumn in 1433, given that he had made his will a few months earlier. In the will, dated 25 Apr. that year,
Having made his will, Hastyng lived for well over another year. He completed his last term as bailiff, and he was among those in Norfolk expected to swear the oath to keep the peace administered throughout England in 1434.
