UNIDROIT Convention on Stolen or Illegally Exported Cultural Objects (Rome, 1995) is the international treaty on the subject of cultural property protection. It attempts to strengthen the main weaknesses of the 1970 UNESCO Convention on the Means of Prohibiting and Preventing the Illicit Import, Export and Transfer of Ownership of Cultural Property. The UNIDROIT Convention seeks to fight the illicit trafficking of cultural property by modifying the buyer's behaviour, obliging him/her to check the legitimacy of their purchase.
