Liechtenstein [3] or Liechtenstein (form officially used by the European Union [4]) is a tiny principality, a microestado, located in the heart of Europe, wedged in the Alps, between Austria, east, west and Switzerland. Slightly more than 34 thousand people live in the principality of only 160 square kilometers.

Since the fifteenth century, has virtually the same territory and the principality is controlled by the same family since 1608, when Liechtenstein became independent of the Germanic Holy Roman Empire. For having been part of the German empire and directly off it, the language spoken in the country is German, but Liechtenstein is different from Germany and Austria, as a micro-state, one of the richest in the world, and is constantly cited as a place where the practice of money laundering (or money laundering) is frequent [5].
