we was married in the us so would it be a good idea for him to post it back to me and to get a certified copy and send both? also i know this might be a silly question do i need to change the name in my passport to my new name or wait to change it before i leave america?Where were you married? If in UK, you need a certified copy issued by the registrar (or clergy if it was a Church of England or Church in Wales ceremony). You can send the original created at the time of the ceremony, but certified copy would be sufficient. If in US, you need a certified copy issued by vital records of the state you were married in. You should be able to order either by mail.
