In the contemporary world, the predominant form of criminality at both national and international level are crimes against property of natural and legal persons, as well as crimes against property owned by the state. When committing these crimes, individuals, groups and organizations perform their criminal activities with intention to obtain illegal material gain. Considering it insufficient, the offenders try to 'legalize' the money and other illicitly obtained financial gain, i.e. to put the illegal proceeds into legal circulation in order to 'create' a legal ground for their acquisition. On the other hand, the perpetrators of these criminal offences also need to conceal the real sources (or origin) of illicitly obtained money and material gain. Individual states as well as the entire international community have recognized the imminent danger arising from these criminal activities, committed by groups and individuals involved in money laundering and hiding the money and other illegally obtained financial gain. Accordingly, international law and the national criminal law of Serbia prescribe the criminal offence of money laundering, which entails criminal liability and strict punishment aimed at preventing and suppressing these socially dangerous activities.
