The Singapore Embassy in Beijing is not authorised to solemnise or register marriages.
The Embassy and the Singapore Registry of Marriages (ROM)/ Registry of Muslim Marriages (ROMM) do not issue Certificates of No Impediment (无配偶证明). You may apply to ROM/ ROMM at http://www.marriage.gov.sg/ to obtain the official Search for Marriage Records conducted on the marriage registers. The official search result can be collected at ROM/ ROMM or delivered to you by mail. Delivery to an overseas address via registered post may take longer. The Embassy may provide only a Letter of Marriage Record, where it is required by the Chinese authorities (e.g., with a written request from a Chinese authority).
Singaporeans who wish to register their marriage in China may provide the Chinese authorities with relevant official documents, which have been duly legalised, as proof of your marital status. These documents may include:
[For more information on legalising your Singapore documents for use in China, kindly refer to the Singapore Academy of Law’s website.]
Alternatively, a statutory declaration affirming your marital status may also be executed in-person at the Embassy. For execution of the statutory declaration, please bring along your valid identity document (i.e., passport), and the relevant original/ certified/ legalised documents corresponding to your marital status/ history.
