Given that Cormyr is one of the most lawful nations in Faerun, its laws are surprisingly undocumented. I've been making an attempt to find and organise all references to elements of law and order.
I know there is a lot more information out there on this topic but its a start.
The Royal Word
The Royal Word are those laws set by the King that are unalterable except by decree from the King himself (or the Royal Magician)
- Commoners must bow their heads in the presence of royalty (Minor).
- Visitors must bow their heads in the presence of a Local Lord (Minor).
- Non-military personnel must carry all weapons openly and those weapons must be tied by "peace strings". Bearing arms is only allowed by those possessing a Charter of Arms, or a Weapons Licence (Medium).
- Everyone must comply to a stop and search request delivered by military personnel (Medium).
- Foreign currency may only be traded by those with a Currency Trading Licence (Minor).
- Hunting in the King's Forest may only be performed by those with a Hunting Licence (Minor).
- Hunting of deer in the King's Forest may only be performed by those with a Stag Hunting Licence (Medium).
- Offences against the Dragon, this applies to all improper depictions of any King or Queen of Cormyr. Lewd, immoral, evil depictions are all classed as improper, and the medium can be anything including literature, paint, sculpture, etc (Minor).
- It is forbidden to unleash magic within the confines of the village known as the Mouth o' Gargoyles (Severe).
- The searching of the magical refuges of the Sword Heralds by the Crown or its agents is strictly prohibited (Capital).
- Possession of banned substances without a Passage Licence is strictly prohibited (Severe).
- The damming or restriction of water-courses is strictly prohibited except for individuals possessing a Water Management Licence.
Court Law
For all disputes and grievances not covered by Crown Law (or in the event of disputes by nobles against Crown Law), Cormyr has created a system known as Court Law.
Court is a formal process whereby one or both parties in the dispute bring the details to the Local Lord of a settlement to adjudicate (with assistance from court magistrates to interpret existing Court and Crown Law). Any decisions made as a result of Court Law are catalogued by the Lord Magistrate (actually his assistants) and stored in the cellars of the Royal Court.
Any appeals against Court Law decisions (a privilege allowed only by nobles or with Crown approval) are taken to the Royal Court in Suzail to be heard by a jury of peers.
Despite Court Law being a separate process to Crown Law, the Local Lords often adjudicate the application of both Crown and Court Law, and decide all punishments.
Punishment
Crown Law is strictly stratified into a range of severity for individual offences; Minor, Medium, Severe, Capital
Minor offences are punished with fines, confiscation of property, and more rarely with imprisonment for up to 1 day.
Medium offences are punished with loss of licences, confiscation of wealth and property (in punitive proportions) and imprisonment for up to a year
Severe offences are punished with maiming, hard labour for up to 5 years, confiscation of all wealth and property, loss of titles.
Capital offences are usually punished with death, but this can be mitigated to exile or a lifetime of hard labour or in very rare cases the amputation of all limbs (including eyes, ears, and tongue).
Repeat offences can result in punishment being applied at the next level of severity, at the discretion of the Local Lord
Licences
Crown Law forbids many activities in a blanket ban that applies to all (hunting, bearing of arms, selling weapons, trading in foreign currency, etc. The Crown gathers a substantial source of revenue from the sale of licences that allow individuals or organisations exemption from specific Crown Laws.
Charter of Arms: This licence is otherwise known as the Adventurer's Charter, for it allows an individual or small group of individuals as named on the charter, to bear arms and operate within the boundaries of Cormyr without fear of prosecution.
Currency Trading Licence: Allows the individual or organisation (and those employees of that organisation) to trade specified foreign currencies with foreign nationals that are believed to be in Cormyr on a temporary basis (merchants and caravans, etc).
Hunting Licence: Allows the individual or group of individuals to hunt a quota of small animals (excluding deer, stag, and all exotic beasts), within the confines of the King's Forest for a defined period of time as specified on the licence. These licences are often granted to entire settlements laying within the confines of the King's Forest, allowing all residents of said settlement to hunt a reasonable number of animals (to provide sustenance) for an indefinite period of time. Licences can otherwise be bought by those wishing to go on hunting expeditions into the forest.
Land Licence: Allows the named individual or group of individuals or organisation to own a specified area of land for a defined period of time. These licences can be hereditary (but usually not) and the terms of inheritance are strictly defined (patri or matrilineal, primo or ultimogeniture).
Logging Licence: Allows the individual to fell a specified number of trees from a specified area within the King's Forest.
Marriage Licence: Allows the named individuals to form a cooperative partnership including the equal sharing of assets and responsibility.
Passage Licence: Allows the individual or organisation (and those employees of that organisation) to transport banned or controlled items (as specified by the licence and including things like poison, dangerous animals, weapons, foreign currency, smoke powder, etc). All items must be transported in secured containers. The licence specifies the number of containers allowed to be transported by the licence, and the place of origin and place of destination. This licence is typically issued from the place of origin and destroyed by officials at the place of destination (after an inspection to ensure the terms of the licence have been complied with).
Smithing Licence: Allows the individual or organisation (and those employees of that organisation) to produce manufactured goods from base metals. The licence specifies the types of goods permitted to be manufactured (i.e. decorative, miscellaneous, arms and armour, etc).
Stag Hunting Licence: Allows the named individual to hunt a defined number of deer and stag (including pregnant and young deer) within the confines of the King's Forest for a defined period of time as specified on the licence. Licence costs range from 10,000 to 100,000 gold pieces at a rate of 1,000 gold pieces per day.
Trade Fair Licence: Allows the individual access to a trade fair. Typically issued at the site of entry to an official Trade Fair and costs vary from 1 copper piece to 1 silver piece (for those trade fairs in Suzail).
Water Management Licence: Allows the named individual or organisation (and those employees of that organisation) to modify waterways, including damming, redirection, and restriction. These licences are typically required for those wishing to operate a mill.
Weapons Licence: Allows the named individual or organisation (and those employees of that organisation) to bear arms within a specified location or locations for the purposes of selling those arms to customers providing said customers are in possession of a Charter of Arms or are representatives of the Crown.
