Birth Certificates in Thailand

A birth certificate is an important official document that records and verifies a person's birth in Thailand. It may be required for matters such as household registration, nationality applications, passport applications, proving the legal relationship between parents and a child, inheritance, and family-related legal proceedings.

Under the Civil Registration Act B.E. 2534 (1991), as amended, the Department of Provincial Administration is the principal government authority responsible for civil registration matters.

What Is a Birth Certificate?

A birth certificate is an official civil registration document containing information about a person's birth, including:

• The child's name and surname
• Date of birth
• Place of birth
• Information concerning the father and mother
• Nationality information
• Information concerning the person who reported the birth

This information may later be important in establishing a person's identity, nationality, and legal family relationships.

How Long Do You Have to Register a Birth in Thailand?

In general, a birth must be reported to the registrar within 15 days from the date of birth when the child is born in a house.

Different rules may apply where a child is born outside a house, including requirements concerning the place and procedure for reporting the birth.

Timely birth registration is generally straightforward. If the birth is reported late, additional procedures and investigation may be required.

Can a Child Born in Thailand to a Foreign Parent Obtain a Thai Birth Certificate?

Yes. A child born in Thailand can generally have the birth officially registered even where one or both parents are foreign nationals.

However, the child's registration status and the information recorded on the relevant civil registration documents depend on the circumstances of the parents and the child.

Importantly, having a Thai birth certificate does not automatically mean that the child is a Thai citizen in every case. Birth registration and nationality are separate legal issues and must be considered under the applicable Thai nationality laws.

What Documents Are Required to Register a Birth?

The documents required may vary depending on the circumstances, but commonly include:

1. 01Identification documentsIdentification documents or passport of the person reporting the birth.
2. 02Hospital birth notificationA hospital or medical facility birth notification, such as Form Tor Ror 1/1.
3. 03Parents' identificationIdentification documents of the father and mother.
4. 04House registrationHouse registration documents, where applicable.
5. 05Power of attorneyA power of attorney or authorization document if another person is acting on behalf of the parent.

Foreign parents should ensure that their passports and other relevant documents are properly prepared before visiting the registrar.

What Happens If the Birth Is Not Registered Within 15 Days?

If the birth is reported after the statutory period, it is considered a late birth registration.

The registrar may conduct additional inquiries concerning:

• The circumstances of the birth
• The reason for the delay
• The identity of the parents
• The identity of the child
• Evidence proving that the child was born as reported

If there is no hospital birth notification, other evidence may be required to establish the child's birth and parentage. Depending on the circumstances, DNA testing may also become relevant in establishing biological parentage.

Can the Father's Name Be Added to a Birth Certificate Later?

There are circumstances in which information concerning the father may be added or corrected after the original birth registration.

However, the procedure depends on the legal relationship between the parents and the legal status of the father.

This can be particularly important where:

• The father is a foreign national
• The parents were not legally married
• The father wishes to legally establish his relationship with the child
• The father's name was not recorded on the original birth certificate
• There is a dispute regarding biological or legal paternity

In certain disputed cases, court proceedings may be necessary to establish legal parentage.

What If the Birth Certificate Is Lost?

If the original birth certificate has been lost, a person may generally request a certified copy of the birth registration record from the relevant civil registration office.

The applicant may need to provide identification documents and other information necessary for the registrar to locate the relevant registration record. Government fees may apply.

Why Is a Birth Certificate Important for Foreign Families?

For families involving foreign nationals, a child's Thai birth certificate may be required for many legal and administrative purposes, including:

• Applying for or proving nationality
• Applying for a passport
• International travel
• Visa and immigration matters
• Proving the relationship between a parent and child
• Child custody proceedings
• Child support matters
• Inheritance and probate proceedings
• Submitting documents to foreign government authorities

For this reason, parents should carefully check that the information recorded on the birth certificate is accurate.

Using a Thai Birth Certificate Overseas

If a Thai birth certificate is required for use in another country, additional document formalities may be necessary.

Depending on the requirements of the destination country, these may include:

• Obtaining a certified copy of the birth registration
• Translating the document into the required language
• Certification or legalization of the translation
• Legalization or authentication by the relevant Thai authorities
• Additional certification by the embassy or authority of the destination country

The exact requirements depend on the country where the document will be used.

When Should You Consult a Lawyer?

Birth registration may appear to be a simple administrative matter, but certain cases involve significant legal issues, particularly where a foreign national is involved.

Legal advice may be appropriate when:

• The father or mother is a foreign national
• The parents are not legally married
• There is a dispute concerning paternity
• The father's or mother's name needs to be added or corrected
• The child does not have a hospital birth notification
• The birth was registered late
• The child has no clear civil registration status
• The child's nationality is uncertain
• The birth certificate must be used overseas
• A parent cannot personally attend the registration office
• There is a dispute concerning parental rights or custody

Obtaining legal advice before submitting documents to the authorities can help identify potential problems and reduce unnecessary delays.
