According to the relevant provisions of China's criminal law, the limitation of prosecution for fraud is 20 years. Because the limitation of prosecution is determined by the statutory maximum penalty for the crime that the suspect is accused of. If the statutory maximum penalty for a crime is less than 5 years, the limitation of prosecution shall be 5 years; If the statutory maximum penalty for a crime is more than 5 years but less than 10 years, the limitation of prosecution shall be 10 years; If the statutory maximum penalty for this crime is fixed-term imprisonment of 10 years or more, the limitation of prosecution is 15 years; If the statutory maximum penalty for this crime is life imprisonment or death penalty, the limitation of prosecution is 20 years. After 20 years, if the procuratorate deems it necessary to prosecute, it shall report to the Supreme People's Procuratorate for approval. The statutory maximum penalty for fraud is life imprisonment, so the limitation of prosecution is 20 years. After 20 years, the procuratorate has no right to investigate his criminal responsibility.
