Private He Jiang Xian of the Glorious and Wonderful Arabel City Militia, proud member of the etc. etc. etc., enters into the Library asking after books about property law, deeds, and land ownership in the Kingdom of Cormyr long may it prosper, etc. etc. etc.
Specifically she asks about the laws regarding 'land fraud'.
The attempt to purchase or sale lands that are not in one's legal possession (shown by a deed issued by a Herald of the King or agent)is considered fraud.
Much like fencing stolen property is criminal (as is its possession) so is the attempt to sell land that is not yours.
The librarian notes that the actual book of law is hundreds of pages long, filled with precedent and tradition otherwise known as 'common law' (which he says is another term for 'common sense,') and that the book of law in the library is a watered down version meant for the general public to grasp. Legal scholars spend years studying the book of law to understand its nuances and previous judgments so precedents are set and followed. He doesn't expect a foreigner to completely grasp the heart of the matter, but states that all land is Cormyr is technically owned by the Crown, and that the nobility are stewards of said territory and land.
But to the heart of the matter,
In essence, it is criminal to sell which is not yours.
The Private He, etc. etc., spends a little time slowly pouring over the old legal codes anyway, apparently for her own interest.
She eventually comes back, asking to clarify who precisely is capable of writing deeds on lands hitherto unrepresented by a deed or held within the common law by the Crown. Would that be, she asks in her shy eastern accent, a deed would need to be written by the King himself?
Would it be issuable, she asks, for instance, by a Purple Dragon Knight, a War Wizard, or a more direct representative like the Warden of the North? More or less she asks what, exactly, constitutes a Herald of the King.
The librarian explains that Heralds of the King, much like the one that used to issue the adviser cloaks in Maleen's Spire, have the authority to act on behalf of the king in such circumstances, as the king needn't approve every property and deed transfer, merely those that involve large swathes of territory.
Ah, she says, how wise that is to structure this in that way.
Then she asks about whether or not the Warden of the North has a Herald, or the City Council, and whether they are the same Herald, or whether they are different after all. She asks, once again quite embarassed at her lack of knowledge, about whether, indeed, the Warden has any authority over land matters at all, or whether his Herald does, instead. She also says sorry a lot but this isn't her first language, and she has to be sure.
