Previously I asked for certified replicas and got them from the county court where we were married and the probate judge was who we contacted. This was in S.C. Hope something here helps.
yes, we did it a while ago at the CM US consulate. We just did an affidavit and they stamped/certified that. 50 bucks. You then get it translated into thai and get it approved by the MFA. If you need a thai version of marriage certificate, you take the MFA certified document with a translated US marriage certificate to your local Amphur and they issue you a registered thai marriage certificate called a korror22, 200 baht i think it was. Oddly the US consulate didnt want to see the US certificate, didnt read the affidavit and didn't even ask what it was about. just stamped it up asked me to raise my right hand and swear and hand over the cash.
