Not a visa question really, but will affect my visa application if I can get married :-) My Thai partner was divorced in UK 3 years ago and we have the certificate. I have my affirmation legalised at the MFA. One of the translators we spoe to said we would need my partners UK divorce document "translated and legalised" in the UK. I never heard of this and cannot find any reference to this on internet. All I can find is that we need the divorce documents with us, which we have. It was ok for mine so cannot see why it would not be ok for hers?
TLDR : Answer Summary
The question revolves around the requirement of having a Thai partner's UK divorce document translated and legalized in order to register a marriage in Thailand. The poster has their own affirmation legalized but is uncertain whether the same is needed for their partner's divorce papers, which were adequate for their prior marriage. Comments suggest confirming the requirements at the Amphur office where the marriage will be registered.
