TLDR : Answer Summary
The discussion revolves around the use of a Certificate of No Impediment (CNI) issued in the UK for marrying in Thailand. Users clarify that a CNI proves you are eligible to marry and must be processed at the UK Embassy in Bangkok. The certificate should be in both English and Thai, having the appropriate stamps for legality. Additional requirements include having your divorce certificate if previously married, or a death certificate if your spouse has passed away, along with the ID card of your fiancée.

MUST be done at the UK Embassy in Bangkok you will need your actual divorce certificate if previously married and if your former wife passed away the death certificate. You will also need a copy of your wife to be ID card.
