I married my Thai wife abroad, will our foreign marriage be valid in Thailand? Or do we need to visit the district office or Amphur in Thailand to marry again under Thai law?
A marriage in a foreign country between Thai nationals or between a Thai national and a foreigner may legally take effect according to the form prescribed by Thai law or by the law of the country where it takes place. If being legally married abroad, there is no need to register your marriage again in Thailand, but a need to report and update status of the Thai national.
A visit to the Thai embassy in your location will be required to have your marriage certificates authenticated or certified. Once in Thailand, the Thai national needs to visit the district office in her hometown to update status and obtain Kor Ror 22. The said document shall serve as a proof of your legal marriage registration.
