A system of registration and enforcement of commercial agreements was established by statute. Merchants could obtain a writing of a debt sealed by the debtor and authenticated by royal seal or a seal of a mayor of certain towns, and kept by the creditor. Failure to pay a such a debt was punishable by imprisonment and, after three months, the selling of borough tenements and chattels and of county lands. During the three months, the merchant held this property in a new tenure of "statute merchant". (Prior to this, it was difficult for a foreign merchant to collect a debt because he could not appear in court which did not recognize him as one of its proper "suitors" or constituents, so he had to trust a local attorney. Also, the remedy was inadequate because the history of the law of debt was based on debt as a substitute for the blood feud, so that failure to pay meant slavery or death. Also a debtor's land was protected by feudal custom, which was contrary to the idea of imposing a new tenant on a lord.)

"In no city, borough, town, market, or fair shall a person of the realm be distrained for a debt for which he is not the debtor or pledge."

Anyone making those passing with goods through their jurisdiction answer to them in excess of their jurisdiction shall be grievously amerced to the King.

No market town shall take an outrageous toll contrary to the common custom of the nation.

Since good sterling money has been counterfeited with base and false metal outside the nation and then brought in, foreigners found in the nation's ports with this false money shall forfeit their lives. Anyone bringing money into the nation must have it examined at his port of entry. Payments of money shall be made only by coin of the appropriate weight delivered by the Warden of the Exchange and marked with the King's mark. (A currency exchange was established at Dover for the exchange of foreign currency for English sterling.)

The silver in craftwork must be sterling and marked with the Leopard's Head. The gold in craftwork must meet the standard of the Touch of Paris.

The assize of bread and ale had been and was enforced locally by local inspectors. Now, the Crown appointed royal officers for the gauge of wines and measurement of cloths. Edicts disallowed middlemen from raising prices against consumers by such practices as forestalling [intercepting goods before they reached the market and then reselling them] or engrossing [buying a large supply of a commodity to drive up the price] and price regulation was attempted. For instance, prices were set for poultry and lamb, in a period of plenty. Maximum prices were set for cattle, pigs, sheep, poultry, and eggs in 1314, but these prices were hard to enforce. In London examples of prices set are: best hen 3d.2q., best wild goose 4d., best hare 4d., best kid 10d., best lamb 4d., best fresh herrings 12 for 1d., best pickled herrings 20 for 1d., best haddock 2d., best fresh salmon 3s.

Freemen may drive their swine through the King's demesne Forest to feed in their own woods or elsewhere. No man shall lose his life or limb for killing deer in the Forest, but instead shall be grievously fined or imprisoned for a year.

The Forest Charter allowed a man to cut down and take wood from his own woods in the King's forest to repair his house, fences, and hedges. He may also enclose his woods in the King's forest with fences and hedges to grow new trees and keep cattle and beasts therefrom. After seven years growth of these new trees, he may cut them down for sale with the King's permission.

Each borough has its own civil and criminal ordinances and police jurisdiction. Borough courts tended to deal with more laws than other local courts because of the borough's denser populations, which were composed of merchants, manufacturers, and traders, as well as those engaged in agriculture. Only borough courts have jurisdiction over fairs. In some boroughs the villein who resides for a year and a day becomes free. There are special ordinances relating to apprentices. There are sometimes ordinances against enticing away servants bound by agreement to serve another. The wife who is a trader is regarded in many places as a feme sole [single woman rather than a feme covert [woman-covert], who was under the protection of a husband]. There may be special ordinances as to the liability of masters for the acts of their apprentices and agents, or as to brokers, debt, or earnest money binding a bargain. The criminal and police jurisdiction in the borough was organized upon the same model as in the country at large, and was controlled by the King's courts upon similar principles, though there are some survivals of old rules, such as mention of the bot and the wer. The crimes committed are similar to those of the country, such as violence, breaches of the assize of bread and beer, stirring up suits before the ecclesiastical courts, digging up or obstructing the highway, not being enrolled in a tithing, encroachments upon or obstructions of rights of common. The most striking difference with the country at large are the ordinances on the repair or demolition of buildings, encroachments on another's building, fires, and nuisances. Specimens of other characteristic urban disputes are: selling bad food, using bad materials, unskillful or careless workmanship, fraudulent weights and measures, fraud in buying and selling, forestalling or regrating [buying in one market to resell in another market], acting in a way likely to endanger the liberties of the borough, usury, trading without being a citizen, assisting other unlicensed persons to trade, unlawfully forming a guild, complaints against various guilds in which trade might be organized. Since the ordinances were always liable to be called in question before the King's courts, they tended to become uniform and in harmony with the principles of the common law. Also, trading between boroughs kept them knowledgeable about each other's customs and conditions for trade, which then tended to standardize. Boroughs often had seals to prove communal consent and tended to act as a corporate body.
