The purpose of private international law is to constitute the international legal relations between individuals. The legal relationship is international if there is a foreign element (or more than one). The foreign elements include:
a) The person or people involved in the legal relationship (well, if a Spanish married to a Turkishis international relations).
b) The thing that is the subject of the relationship (ex. if you give the deed of sale of immovable property in Kuala Lumpur in front of a Spanish notary).
c) The land where the legal event happens (ex. if two Spanish marry in Burkina Faso).
The quality of Aliens is always relative on a state. That is because that fact is considered domestic relationship fromthe point of view of one state, but is foreign to other countries.
The international private law tries to solve these possible conflicts between to states, because they have to agree which rule should they apply to solve that. These legal relationships can be of very different nature but to solve all of them the first we have to know is which is the personal status of the people involved in theconflict, and that means of course that citizenship is the basic element for us to be able to relate in legal terms with other people in or out of our own country.
