Things to know about naming and the use of the child's last name 

• The Royal Thai Embassy in Singapore will issue a Birth Certificate (Thai) by give the name and surname according to Singapore Birth Certificate which must comply with Thai law. The child’s name on the Birth Certificate issued by the local authority of Singapore must match the name of the child who reported the birth to the Embassy, which must be in line with Thai law. If the applicant wants to apply for Thai nationality for the child, the name of the child should be consistent with Thai law.
• According to law of Thailand, a child must use only the surname of the father or mother. For the Birth Certificate (Singapore), the child must use the same surname of father or mother which cannot create a new surname or combine the surnames of parents together.
• If the father is dose not have a surname, the mother's surname must be used in the Birth Certificate, along with the testimony in front of consular officers and the record of the interrogation to confirm the use of the mother's surname. However, if the father does not allow the child to use the mother's last name, consular officers will not accept the application and cannot issue the birth certificate.
• If the child's Birth Certificate (Singapore) has a different surname as father's surname, consular officers will not accept the application and cannot issue the birth certificate.
• Child's name and surname on Birth Certificates (Thai) consists of the following:

(1) First name

(2) Middle name

(3) Surname or Family name

The recording of a Thai name on a Thai birth certificate is divided into three parts: given name, middle name, and surname.

If a given name or middle name appearing with a space between the names on a local Singapore birth certificate is to be recorded on a Thai birth certificate, under Thai law, the names must be written without spaces within that particular name section. The order of the name and surname on the Thai birth certificate must be:

Given Name – Middle Name – Surname, respectively.

For example, suppose the name appearing on the Singapore birth certificate is:

Xiao Chen Lee, Xiao Zhu

and the applicant chooses to register the child's name on the Thai birth certificate as follows:

• Given name: Xiao Chen
• Middle name: Xiao Zhu
• Surname: Lee

The name and surname on the Thai birth certificate would therefore be recorded as:

• Given name: เสี่ยวเฉิน (written without a space)
• Middle name: เสี่ยวจู (written without a space)
• Surname: ลี

In the English section, the spaces between the names may remain as they appear on the local Singapore birth certificate. However, the order of the names must follow the Thai regulations governing the issuance of Thai birth certificates. Therefore, the English name would appear as:

Xiao Chen Xiao Zhu Lee

If the name appearing on the local Singapore birth certificate contains more than three separate parts, for example four or five parts separated by spaces, when the name is recorded in the Thai-language section of the Thai birth certificate, the applicant must choose to combine the relevant names without spaces within either the given-name section or the middle-name section. It is not possible to have more than three separate sections/spaces in the Thai name structure.

For example, suppose the name appearing on the Singapore birth certificate is:

Xiao Chen Somchai Lee, Xiao Zhu

and the applicant chooses to register the child's name on the Thai birth certificate as follows:

• Given name: Xiao Chen Somchai
• Middle name: Xiao Zhu
• Surname: Lee

The name and surname on the Thai birth certificate would therefore be recorded as:

• Given name: เสี่ยวเฉินสมชาย (written without spaces)
• Middle name: เสี่ยวจู (written without spaces)
• Surname: ลี

Alternatively, if the applicant wishes to place “Somchai” together with the middle name, this is also possible. The Thai birth certificate would then record the name as:

• Given name: เสี่ยวเฉิน (written without a space)
• Middle name: สมชายเสี่ยวจู (written without a space)
• Surname: ลี

In the English section, the spaces may remain exactly as they appear on the local Singapore birth certificate. However, the order of the names must follow the Thai regulations for the issuance of Thai birth certificates. Therefore, the English name would appear as:

Xiao Chen Somchai Xiao Zhu Lee

Cases Where the Father Does Not Have a Surname

For a minor whose father does not have a surname, and whose name on the local Singapore birth certificate was not established in accordance with Thai naming laws, if the surname of the child does not correspond to the name used by the father, the mother's surname must be used instead on the Thai birth certificate.

For example, suppose the name appearing on the Singapore birth certificate is:

Somying Binte Muhammad

The minor's father is named:

Muhammad Bin Abdullah

The minor's mother is named:

สมปอง ใจดี (Sompong Jaidee)

In this case, it can be seen that the surname/name appearing at the end of the child's name does not correspond to that of the father. This is because the father is a person who does not have a surname; instead, the father's name has been incorporated into the child's name.

Therefore, when issuing the Thai birth certificate, it is not possible to register the child as “สมหญิง นามสกุล บินตี้ มูฮัมหมัด” (Somying, surname Binte Muhammad).

This is because the father's name appears as “Bin Abdullah”, whereas the child's name contains “Binte Muhammad.” These do not constitute the same surname or family name.

Accordingly, the surname of the Thai mother must be used instead on the Thai birth certificate. Under Thai naming requirements, a child must use the surname of either the father or the mother, and the surname used must correspond to the surname of that parent. This is in accordance with the explanation provided above regarding the requirements and considerations for naming a child and using a surname.

The child's name on the Thai birth certificate would therefore be recorded as follows:

English:

• Given name: Somying
• Middle name: Binte Muhammad
• Surname: Jaidee

Thai:

• Given name: สมหญิง
• Middle name: บินตี้มูฮัมหมัด (written without a space)
• Surname: ใจดี

In the English section, the spaces between the names may remain as they appear on the local Singapore birth certificate. However, the surname must be added in accordance with the Thai regulations for issuing a Thai birth certificate. Therefore, the complete English name would appear as:

Somying Binte Muhammad Jaidee

Possible Difference Between the Child's Thai and Singaporean Nationality Documents

As a result, the child's name appearing on the Thai nationality documents and the documents of the child's other nationality may not be identical.

Therefore, if the applicant intends to apply for Thai nationality for the child as well, it is advisable to register the child's name on the Singapore birth certificate in a manner that is consistent with the naming requirements under Thai law. This will help ensure that the child's documents relating to both nationalities contain the same name.

However, if the applicant has already registered a name that is not consistent with Thai naming requirements, the consular officer will prepare an interview/statement record confirming the use of the mother's surname. Both the mother and father will be required to sign and acknowledge the record, which will be attached to the application for issuance of the Thai birth certificate.

This supporting document will be in Thai and will be used solely as a supporting document for the issuance of the Thai birth certificate. It will confirm that the child is required to use the mother's surname because the father does not have a surname.

• A middle name is not a required element of birth registration. It may or may not have, depending on the Birth Certificate (Singapore).
• In the case of a legitimate child, there is the right to use the mother’s or the father’s surname as a middle name, if it corresponds to the Birth Certificate (Singapore).
• The spelling of the child's name in Thai on the Birth Certificate (Thai) which will be issued by the Royal Thai Embassy must match the English language on the Birth Certificate (Singapore) and spell in the same sound as closely as possible with that language.

  The following examples illustrate which documents must be authenticated in different circumstances.

  The Singapore documents that must be authenticated by either SAL or a Singapore Notary Public followed by SAL authentication are:

• If parents are Foreign citizens (not Singapore citizens).

- Where the Father or Mother Is a Foreign National Other Than a Singaporean Citizen

Government documents issued by a country other than Singapore and Thailand must first be authenticated by the Embassy or Consulate of that country in Singapore before they can be submitted to the Royal Thai Embassy.

The requirements are as follows:

Foreign Passports

The foreign passport of the father, mother, and/or minor must be authenticated by the Embassy or Consulate of the country that issued the passport.

For example, if the father is a German citizen, the father's German passport must be authenticated by the Embassy of Germany in Singapore.

Foreign Marriage Certificates

A marriage certificate issued by a country other than Singapore or Thailand must also be properly authenticated.

If the marriage certificate is not in English, it is advisable to prepare a translation into a third language in accordance with the regulations of the Ministry of Foreign Affairs.

This is because, after the Thai birth certificate has been issued, the child's name will need to be entered into the household registration in Thailand. Some district offices in Thailand may require the marriage certificate to be translated into Thai and the translation to be officially certified.

However, if the marriage certificate was issued by a country other than Thailand or Singapore, it is recommended that the applicant have the document translated and the translation certified in the country where the marriage was registered. This will generally be more convenient for the applicant than having the translation prepared and certified in Singapore.

- Special Cases for Certain Nationalities

If the father or mother holds one of the following nationalities, the procedures below apply.

British or Japanese Citizen

For a father or mother who is a British (United Kingdom) or Japanese citizen, the British High Commission/Embassy and the Embassy of Japan in Singapore do not provide document authentication services for this purpose.

Therefore, the applicant may proceed with document authentication in the same manner as in the case where the father or mother is a Singaporean citizen, i.e., through the applicable Singapore authentication process involving a Singapore Notary Public and/or the Singapore Academy of Law, as appropriate.

Indonesian Citizen

For a father or mother who is an Indonesian citizen, if the Indonesian passport was not issued at the Embassy of Indonesia in Singapore, the Embassy of Indonesia in Singapore does not provide authentication of the document.

Therefore, the applicant may proceed with document authentication in the same manner as in the case where the father or mother is a Singaporean citizen.

- Procedure for Combining Foreign and Singapore Documents

Once the foreign passport(s) of the father, mother, and/or minor have been authenticated by the Embassy or Consulate of the relevant country in Singapore, the authenticated foreign documents should be combined with the relevant Singapore government documents into one set.

The documents should include, as applicable:

• Authenticated foreign passport(s) of the father, mother, and/or minor
• The minor's Singapore birth certificate
• Singapore residence permits of the father and mother
• Singapore marriage certificate

The complete set of documents should then proceed through the following authentication process:

1. Have the documents authenticated by a Singapore Notary Public. The documents authenticated by the Notary Public may be bound together as one set using corner binding.
2. Have the Notary Public's authentication subsequently authenticated by the Singapore Academy of Law (SAL).
3. Once the documents have been received, make one additional photocopy set for submission to the Royal Thai Embassy. The fee charged by the Singapore Notary Public for notarizing/authenticating the documents should be confirmed directly with the Notary Public.
4. On the date of the Thai birth certificate application, the Royal Thai Embassy will authenticate the relevant Singapore Notary Public/SAL authentication. The Embassy's fee is SGD 30 per set.

For documents issued by the Thai authorities, please submit the original documents together with one photocopy set, as follows:

• Thai passport of the father or mother
• Thai National Identification Card of the father or mother
• Copy of the Thai household registration (Tabien Baan) of the father or mother
  (A copy of the household registration is acceptable.)
• Thai marriage certificate, if applicable

If the parents registered their marriage in Singapore, the Singapore marriage certificate will instead be included among the foreign/Singapore documents that are authenticated through the Singapore Notary Public + SAL process.

The processing of the documents takes 7 working days.
