Royal coroners held inquests on all sudden deaths to determine whether they were accidental or not. If not, royal justices held trial. They also had duties in treasure trove and shipwreck cases. Justices of assize, justices of the peace, and itinerant justices operated at the county level. The traditional county courts had lost much jurisdiction to the royal courts and were now limited to personal actions in causes involving usually no more than 40s. There were pleas of trespass and debt, unjust seizure and detention of beasts, rent collection, claims of fugitive villeins and their goods, nuisances, and encroachments. The sheriff still constitutes and conducts the court. The county court met every three or four weeks, usually in the sheriff's castle located in the chief borough of the county, but some met in the open air. Twice a year the sheriff visited each hundred in the county to hold a turn [court for small offenses, such as encroachment of public land, brewing and baking contrary to government regulations, and use of dishonest weights and measures.]. Everyone who held freehold land in the hundred except the greater magnates had to attend or be fined for absence. The sheriff annually viewed frankpledge, in which every layman without land that could be forfeited for felony, including villeins, were checked for being in a tithing, a group of neighbors responsible for each other's good conduct. This applied to every boy who had reached the age of twelve. He had to swear on the Bible "I will be a lawful man and bear loyalty to our lord the King and his heirs, and I will be justiciable to my chief tithing man, so help me God and the saints." Each tithing man paid a penny to the sheriff. The hundred court decided cases of theft, viewing of boundaries of land, claims for tenurial services, claims for homage, relief, and for wardship; enfeoffments made, battery and brawls not amounting to felony, wounding and maiming of beasts, collection of debts, trespass, detinue [detention of personal property which originally was rightfully acquired] and covenant, which now requires a sealed writing; defamation, and inquiries and presentments arising from the assizes of bread and ale and measures. A paid bailiff had responsibility for the hundred court, which met every three weeks.
