Forfeiture of the proceeds derived from a relevant offence, or of such property the value of which corresponds to the value of the proceeds, is mandatory under CC Article 23B. Confiscation is imposed in addition to other applicable sanctions. CC Article 23 also provides for the forfeiture of instruments used or intended to be used in the commission of any crime, and of any property obtained by such crime, as a consequence of the punishment for the crime established by law. Immovable property is confiscated through judicial sale by auction or by claim and possession. Asset tracing, freezing and seizing are authorized through investigation, attachment and freezing orders under the CC and PMLA. As regards the rights of bona fide third parties, CC Article 23 (1) provides for the forfeiture of criminal proceeds “unless some person who has not participated in the crime has a claim to such property”.
