Crown pleas included issues of the King's property, fines due to him, murder (a body found with no witnesses to a killing), homicide (a killing for which there were witnesses), rape, wounding, mayhem, consorting, larceny, robbery, burglary, arson, poaching, unjust imprisonment, selling cloth by non-standard widths, selling wine by non-standard weights. Crown causes were pled by the king's serjeants or servants at law, who were not clerics. Apprentices at law learned pleading from them.

Between the proprietary action and the possessory assizes there is growing use in the king's courts of writs of entry, by which a tenant may be ordered to give up land, e.g. by a recent flaw in a tenant's title, for a term which has expired, by a widow for her late husband's land, or by an heir who has become of full age from his guardian. For instance: " …Command Tertius that … he render to Claimant, who is of full age, as it is said, ten acres …which he claims to be his right and inheritance and into which the said Tertius has no entry save by Secundus, to whom Primus demised [gaged] them, who had only the wardship thereof while the aforesaid Claimant was under age, as he says…". But most litigation about land is still through the writ of right for proprietary issues and the assizes of novel disseisin and mort d'ancestor for possessory issues.

Royal itinerant justices traveled to the counties every seven years. There, they gave interrogatories to local assizes of twelve men to determine what had happened there since the last eyre. All boroughs had to send twelve burgesses who were to indict any burgesses suspected of breaking the royal law. Every crime, every invasion of royal rights, and every neglect of police duties was to be presented and tried. Suspects were held in gaol until their cases could be heard and gaol breaks were common. Punishment after trial was prison for serious crimes, expulsion from the realm for less serious crimes, and pledges for good behavior for lesser crimes. The visitation of these justices was anticipated with trepidation. In 1237, the residents of Cornwall hid in the woods rather than face the itinerant justices.

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 justicable 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 enquiries 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.

Still in existence is the old self-help law of hamsocne, the thief hand-habbende, the thief back-berend, the old summary procedure where the thief is caught in the act, AEthelstan's laws, Edward the Confessor's laws, and Kent's childwyte [fine for begetting a bastard on a lord's female bond slave]. Under the name of "actio furti" [appeal of larceny] is the old process by which a thief can be pursued and goods vindicated. As before and for centuries later, deodands were forfeited to the king to appease God's wrath. These chattel which caused the death of a person were usually carts, cart teams, horses, boats, or mill-wheels. Then they were forfeited to the community, which paid the king their worth. Sometimes the justices named the charitable purpose for which the deodand was to be spent, such as the price of a boat to go to the repair of a bridge.

Five cases with short summaries are:

CASE: "John Croc was drowned from his horse and cart in the water
of Bickney. Judgment: misadventur. The price of the horse
and cart is 4s.6d. 4s.6d. deodand."
