Ted,
The certificate of no impediment is just that, .... it says that you are single and FREE to marry as of the time the certificate was issued. The Divorce niciei is another document altogether, some guys have never been married!!!
As i said before, if you get your certificate of no impediment from your embassy in China, you don't need this Notary thing, So why would you need if the single certificate is issued in your home county? I'll state again, i've not known anyone getting married in China to need this buckshee certificate, the register office just don't ask for it, only the Chinese embassies in your home countries!!! Just another document to stamp and charge for.....
