The mother or father must sign as the Birth Notifying Person in item 4.8 using either a blue or black ink pen.

Please safely keep the original birth certificate because it can be issued only once. In the event of loss or damage, please contact the Royal Thai Consulate-General in Hong Kong to request for a certified true copy.

The original birth certificate is an essential document used for verification, proof, and confirmation of identity. It serves as primary evidence for registering the child’s name to the house registration in Thailand and directly concerns the individual's civil rights and duties as a Thai citizen such as school enrollment, employment applications, and elections.
