International private law and spanish nationality

INTERNATIONAL PRIVATE LAW AND SPANISH NATIONALITY
Introduction
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.
