Yes, indeed.
The British Embassy, Bangkok website explains what is necessary if you want your official (Amphoe marriage certificate) recorded at the appropriate registry office back in the UK.
My understanding, is that it’s a case of ‘noting’ the Thai marriage, rather than registering it, in the same way a UK marriage would be, but appreciate I may be playing with words.
I don’t work here, nor plan to return to UK with my wife, so do not have issues of tax credits, N.I. numbers, UK passport for my wife etc.
BUT, one can’t be sure what tomorrow might bring and I have had the Bangkok Embassy forward the Thai marriage document and certified English translation to the UK (England) Registry Office. My reason for that is to ensure my wife can receive death grants, widow’s pensions when I depart this world (hopefully later, than sooner!

). Having been in contact with my pension providers, they will certainly require proof of my Thai marriage and MIGHT query anything sent direct from Thailand.
So, whilst my wife speaks fair English, communication between her and UK offices, when I’m no longer here, would not be easy. My eldest son back in UK has my basic will and is the executor, but he will have to ‘call up’ copies of the marriage certificate from the UK Registry Office to satisfy pension providers, banks etc. These documents are, therefore, already recognised as genuine.
