Bigamy is a case of private prosecution. You can directly file a private prosecution with the court, and the court shall accept it. (unless the procuratorate initiates a public prosecution), or report the case to the public security bureau, but the public security bureau may not accept it.
Article 258 of the Criminal Law of People's Republic of China (PRC) stipulates that whoever commits bigamy while having a spouse, or marries someone knowing that they have a spouse, shall be sentenced to fixed-term imprisonment of not more than two years or criminal detention.
The subject of this crime includes both spouse (husband) and unmarried person (mistress) who knows that others have a spouse. Bigamy in this crime includes both legal bigamy and factual bigamy.
It is suggested to keep the evidence of bigamy so that it can be submitted 15 days before the trial.
