I have a similar issue, whereby I am a Canadian, divorced (in Canada) from my first (Canadian) husband in 1988. I remarried in 2015 to a USA citizen that I am now sponsoring.
As the sponsor, I was asked to provide "divorce certificate(s), application(s) for divorce, and divorce order(s)" from my prior marriage, but I had never previously been supplied any of this information from the courts/lawyers.
I attended the Supreme Court where my divorce had been finalized, and obtained a Certificate of Divorce for $40. As far as all the other documents (eg. 'application for divorce' and 'divorce order'), I have no idea what those are, and the courts have told me I have to request this from the Royal Museum (at a cost) if I HOPE to (potentially) locate documents other than a "Certificate of Divorce".
My question is, is a court issued "Certificate of Divorce" sufficient for their purposes, i.e. to establish that I am legally divorced, or will I have to pay to have them dig through the archives to find the "divorce order" and "application for divorce" too?
Thank you.
