The aim of this work is to critically analyse the rules laid down in the Chilean legal system with regard to insurance fraud. This is important, since Law No 20.667 was enacted in May 2013, which fully regulates the case of insurance fraud and adds to the rules of the Commercial Code, as regards remedies against this infringement, a criminal offence that constitutes the offence of insurance fraud, which did not exist before the legal amendment was made. The focus of this study has been on the dogmatic and critical analysis of the new crime of insurance fraud and, specifically, on typical behaviour and iter criminis, as well as on the legislative technique and the political and criminal need for an autonomous criminal type.
