Kertic nationality law
Kertic nationality law is the set of rules which governs the status of being a national and citizen within the country and its subdivisions. It is not a singular piece of legislation, moreso that it is a collection of related legislation and statutes which define the full scope of the system. These laws together determine eligibility of citizenship, responsibilities, and the conditions of losing such status. Kertosono has a two-tiered citizenship system, in which citizens are simultaneously citizens of Kertosono and their respective political entities. To become a citizen of Kertosono, one must be a valid citizen of one of the political entities which make up the country. The definitions of what constitutes a citizen of a political entity differs from entity to entity, however, most are very strict with the definition. All entities operate on a ius sanguinis basis.
Foreigners are eligible to become Kertic citizens given that they meet certain requirements. The law also describes how one could lose Kertic citizenship, which have harsher conditions than other nationality laws. Kertosono does not allow dual citizenship.
Acquisition of Kertic Citizenship
In order to prevent the status of "internal statelesness" in Kertosono, it is impossible to be a Kertic citizen without being a citizen of one of its entities beforehand. Losing that citizenship by any means automatically revokes Kertic citizenship. Since 2005, there has been national legislation regulating citizenship of very common cases, such as birth and acquisition of a different citizenship, and is therefore valid in all entities of Kertosono.
Below is a table for birth conditions.

Only children whose parents are both Kertic are instantly Kertic citizens by means of their entity citizenship. On a more internal level, it is a mix of ius soli and Template:Iuw sanguinis. Babies are automatically granted the citizenship of the entity they are born in if the parents do not register the child in another entity. It is also possible to claim the parent's entities, although both parents must be citizens of the same entity as a requirement for marriage.
