This is substantiated through a Marriage Certificate (Kor Ror 3) and Marriage Registration (Kor Ror 2). If you had married abroad, either you or your spouse must report the marriage to the District Office (Amphur or Khet) and obtain Kor Ror 22.
btw I just got both khor ror 2 and 3 legalized at the Ministry of Foreign Affairs in bangkok. You don't seem to understand that the khor ror 22 is ONLY for registering a marriage in Thailand after you got married outside Thailand. A marriage outside Thailand IS accepted and can be registered inside Thailand. A khor ror 22 is what you need then.
I really don't care what you think. I have a khor ror 2 rigt in front of me. It is freshly printed from the ampheur. It is the updated certificate you get when you are married inside Thailand. If you got married outside Thailand, and register your marriage in Thailand after, a khor ror 22 is what you need in stead of a khor ror 2.
no you are still mistaken. The rose border is NOT khor ror 2. It is Khor ror 3. The updated one you get from ampheur is the khor ror 2 if you got married inside Thailand. The khor ror 22 is ONLY for if you got married OUTSIDE Thailand
most immigration offices require to see both the khor ror 3 (rose border certificate) and an updated certificate khor ror 2 to see you are still married. Because you could be divorced and just keep the khor ror 3.
