I didn't receive any marriage certificate from the civil affairs office.

My wife may have received both of them,but I don't think so.She stayed in China until 1 year after the marriage ,as she didn't have her canadian permanent residency until the end of december 2011.My lawyer said the one I have is a copy,and here in New Brunswick Canada you have to have the original,or a certified copy,and I have a paper saying the copy was a copy of the original.Maybe the lawyer doesn't know the paper is a notarial certificate,but she should know.I live in Canada,and don't plan on going to China.I guess I'll have to try to find the address of the Dalian China Civil Affairs office,or I maybe be able to contact the Canadian embassy in Dalian or Beijing.
