You will need:
  • Both of your valid passports
  • Your arrival card
  • The relevant decree absolute should either of you have been previously divorced.
  • The relevant death certificate should either of you have been previously widowed. 
Please note that all of the above documents must be in their original form. The British Embassy in Bangkok will, in no circumstances, accept copies.
You will need to be:
  • Resident in Thailand for at least three working days. 
  • At least 21 years old. 
Further Information:
  • On arrival in Thailand you will need to attend the British Embassy in Bangkok (find their contact details below) with all of the documents detailed above in order to complete an affirmation that you are both single and free to marry in accordance with Thai Law. The registration will be effected by a Thai Diplomat or Consular Officer.
    • The British Embassy accept affirmations during Consular normal public opening hours (08:00 - 11:00 on Monday - Friday) An appointment for this service is not necessary.
    • This service is provided to British nationals only. 
    • The fee of Baht 3,250 per affirmation is payable.*
  • You must then take the completed affirmation to a reputable translation office to have it translated into Thai. 
  • You will then need to take all of your documents, arrival car, completed declaration and its translation to the Legalisation Division of Consular Affairs department at the Thai Foreign Ministry (find their contact details below), where the Consular Official’s signature from the British Embassy will be authenticated. This usually takes two days.
  • After this, the documents and translation are ready for submission to the District Registrar who will be present at your marriage ceremony. They can then register your marriage and issue your marriage certificate. 
  • Please note that the wedding certificate will be in Thai, so it is recommended that you commission a sworn translation of the marriage certificate into English so that you can use the documents for legal purposes in the UK. 
  • It is NOT a legal requirement that you have your Thai marriage certificate deposited with the General Registry Office in the UK. 
*Please note that the fees may alter without prior notice.
