China citizens who have returned to China for marriage registration shall go through the marriage registration formalities when they return to China. Please notarize the declaration of no spouse at the embassy first. The original China passport and its photocopy (valid within 3 months) or the foreigner's landing card and its photocopy, and the parties concerned shall personally fill in the statement that they have no spouse and no lineal blood relatives and collateral blood relatives within three generations, with clear handwriting and shall not be altered. The applicant signs the declaration in front of the consular officer and writes down the date of the day. Fill in the notarization application form. Divorced or widowed in China, should provide divorce certificate or China court civil mediation book or judgment and valid certificate or death certificate and a copy of the original.
