As long as the formalities are complete, the marriage certificate can be processed at that time. According to the provisions of Article 5 of Chapter 2 of China's Marriage Registration Regulations, mainland residents who handle marriage registration shall present their household registration book, ID card, and signed statement that they have no spouse and no direct blood relatives or collateral blood relations with the other party within three generations. In addition, divorce requires marriage certification materials such as divorce certificates, and collective accounts need to carry permanent population registration cards or household registration certificates.
