As i said, the CENOMAR is dead easy, you goto the website, put in your details, put in your future wifes details. Complete the request, let you mahal print out the receiept/reference number, take it to the bank, pay the small fee, and the CENOMAR will be delivered to her in about 2-3 days. Very Easy.
The website does also allow you to pay for the CENOMAR yourself by credit card and have it delivered to the UK, don't bother with that.
