Article 1 of the Interpretation (II) of the Supreme People's Court on the Application of the Marriage and Family Part of the Civil Code stipulates that if a party requests confirmation of the invalidity of a bigamous marriage based on Article 1051, Item 1 of the Civil Code, and the legal spouse has already divorced or died at the time of filing the lawsuit, and the defendant argues that the subsequent marriage became valid from the occurrence of the above circumstances, the court will not support it.
