The purpose of this study was to examine the legislative and criminological aspects of combatting fraud at the international and national levels. For an effective study of the topic, it was vital to use terminological, hermeneutical, comparative and historical methods. The study covered the essence of fraud as a criminal offence, and identified and analysed the most widespread types of fraud. The study identified the key elements of the crime of fraud: deception, intent of the offender, transfer of property as a result of misrepresentation, mercenary motive and establishment of factual damage. The study found that the key feature that classifies fraud as a criminal offence is the existence of an intentional act. As a result of the study, the international regulatory framework was analysed, as well as the legislation of Kazakhstan and Singapore on combatting fraud. Furthermore, the criminal law and criminological aspects of combatting the crime of fraud were studied through the practices of Kazakhstan and Singapore. The study paid special attention to the need to ensure an effective and complete legal framework in the field of fraud prevention and the development of strong international cooperation on this matter. The study also emphasized the significance of raising public awareness of the fraud situation and conducting educational activities to inform the public about the potential risks.
