Thai Birth Certificates
A child born to a Thai parent (mother or legal father) outside Thailand is entitled to acquire Thai nationality. The parents can apply for a birth certificate for their child in the country of birth. A parent of Thai nationality may apply for his or her child’s birth certificate in person at the Royal Thai Consulate-General, Sydney or by mail. Thai birth certificates are issued free of charge.
Step 1: Authentication
The child’s original Australian birth certificate must be authenticated by the Department of Foreign Affairs and Trade (DFAT).

Step 2: Lodgement
Thai birth certificates are issued free of charge.
Applications can be lodged in person at the Royal Thai Consulate-General, Sydney or by mail.
The following documents are required in order to obtain a Thai birth certificate, and must be presented when lodging the application:
- Application for Legalisation and Birth Certificate Form, fully completed.
- Original and copy of the child’s Australian birth certificate bearing the DFAT seal.
- Current photograph (2 x 2 inches) of the child with the given name and surname specified at the back.
- Original and self-certified copy of the parents’ Thai national ID card, or for a non-Thai parent their Australian driver licence.
- For non-married parent, should the parents wish their child to use the father’s surname, the Consent to use surname for birth certificate form needs to be filled out together with the Thai Birth Certificate application form
- Original and self-certified copy of the parents’ passports.
- Original and self-certified copy of the parents’ Thai house registration.
- Original and self-certified copy of the parents’ marriage certificate.
If the application is submitted by mail, please do not send the original documents. Instead, send copies certified as true by a Justice of the Peace (JP). You must also provide The Royal Thai Consulate-General Sydney with a prepaid express post or registered post envelope for the return of your documents.
The Royal Thai Consulate-General, Sydney needs two full working days to issue a Thai birth certificate.
Advice on first and surname names of the child
- The child’s given name and surname in the Thai birth certificate must be the same as in the Australian birth certificate (that is, written in Thai as it is pronounced in English). Ensure that the child’s Thai names are spelled correctly according to the Office of Royal Society (you may contact the Consular Officer for assistance).
- The child’s last name must be that of their legal father or mother, and the spelling must follow the parent’s Thai documentation.
