As far as I'm aware fella, you don't need to register your marriage in the UK once married in another country. If you married in a country where the UK recognises marriages that take place there, then as far as the UK is concerned, you're married whether you register that fact in the UK or not.
I think the only time you may want/need to register it in the UK is if you were going to divorce in the UK, but no-one here needs to worry about that!![]()
