The view of frankpledge (visus franciplegii), or the duty of ascertaining that the law with regard to frankpledges was complied with, was in the hands of the sheriffs, who held an itinerant court called the "sheriff's tourn" for this and other purposes.
William de Vesci claimed liberties and exemptions in Caythorpe, of which he was summoned to render account at the sheriff's tourn at Halton.
Every three weeks, while twice a year all the freemen of the wapentake were summoned to the view of frankpledge or tourn held by the sheriff.
