The law enforcement and doctrinal features of alternative and indefinite types of intent and the problems associated with their establishment in the law of Russia and Belarus are considered. The paper analyzes the law enforcement practice and pressing issues of interpretation of the intentional form of guilt in accordance with the provisions of the current legislation of Russia and Belarus. The purpose of the paper is a rational and critical consideration of the provisions of the science of criminal law in relation to the question of the classification of criminal acts with an indefinite (unspecified) intent. The author concludes that when establishing the elements of an indefinite (unspecified) intent, the criminal act should be evaluated by the actual consequences. However, it is an inchoate offense that possesses the specifics of classification in this matter.
