[Yokotari]

Laws concerning Polygamy within Yokotari are entirely nonexistent, at least for husbands taking wives. It has been unofficial court-policy for about three hundred years that polyandry (One woman and multiple men) be illegal and punishable. Generally this is done via social contracts rather than by the police, as its seen as disgraceful to allow ones wife to "dominate" the men, or be unable to control her sexual advances with other men. Therefore one would have a difficult time finding a woman who engages in polyandry within Yokotari, barring of course the courtesans of The Imperial Court.

A man taking multiple wives on the other hand, is common, at least for the upper classes. Generally speaking a peasant and artisans and even lower-end merchants are expected to take only one wife, and indeed usually can only obtain this sole partner. Samurai and other high-ranking military leaders may have two wives, assuming they can court two ladies in waiting. Finally the Imperial Family, where one is allowed to take three wives, however it is common practice that one only take a single wife and several concubines, if they must. There are no limits on the amount of concubines a person of the Imperial Family could have, though the common answer is two.

In Erystan, marriage is unrecognized by the state and regarded as a private affair between individuals. Therefore the laws regarding polygamy are the same as the laws regarding unmarried polyamorous relationships, which are legal as long as everyone is consenting. (which also means that all members of relationship are over the age of consent)

Polyamorous relationships are mostly accepted by society, even a conservative minority considers them as morally wrong. Discrimination against polyamorous relationships or individuals are banned by the Federal Anti-Discrimination Law, according to a clause which was added in 1994 by the Federal Chamber, at the request of the Libertarian Party of Erystan.
