Details on the website
"They may be issued in a different name if you have a name change document issued by the Registrar of Births, Deaths and Marriages (RBDM)"

You don't have to change your name by deed poll
It's all about registering the marriage & having a legal marriage certificate
"If married overseas, you may have to register a formal change of name with the Registry before your married surname is accepted by some government or private agencies"
