Can I obtain Kor Ror 2 and 3 if my marriage in Thailand wasn't registered?

The user inquired about obtaining Kor Ror 2 and 3 forms after marrying in Bangkok 16 years ago without registering the marriage. Responses indicated that the absence of registration means the marriage is not legally recognized in Thailand, thus complicating the ability to acquire these forms. However, some suggested that if the marriage was legally conducted overseas (with proper documentation), it might still be possible to register the marriage in Thailand to obtain the Kor Ror forms. Ultimately, a notarized marriage certificate from the overseas jurisdiction is necessary to prove marital status for the documentation needed.
