New sanctions can be applied to individuals providing false or misleading information in the lead-up to a marriage registration, if it is later found to have impacted on the lawful rights and financial interests of their spouse.
The move comes amid escalating efforts to crack down on individuals who default on their credit obligations, and is part of wider efforts by China's government to build a social credit system.
The new sanctions are an outcome of a cooperation memorandum signed by the National Development and Reform Commission, the Ministry of Civil Affairs, the People's Bank of China, and 28 other government departments.
Credit defaulters found to have provided counterfeit or falsified information in the lead-up to a marriage registration can be placed on a national social credit blacklist.
Blacklisted individuals can face up to 14 different punitive sanctions. These include restrictions on working in the civil service, on accessing credit for financing, and on receiving government financial support.
The development of China's social credit system started in 2014. The system has a national online credit information platform where marriage registration blacklist data will also be shared.
