Birth Registration at the Thai Amphur for Foreign Parents (2026)

TL;DR

Every child born on Thai soil must have the birth registered at the local Amphur (ที่ว่าการอำเภอ) — or, in Bangkok, the relevant District Office (สำนักงานเขต) — within 15 days of birth under Section 18 of the Civil Registration Act B.E. 2534 (1991). The hospital issues a Notification of Birth (ใบรับรองการเกิด / Tor Ror 1/1) that the parents take to the Amphur, which then issues the official Thai Birth Certificate (สูติบัตร / Tor Ror 19). Where one parent is Thai, the child acquires Thai nationality by jus sanguinis under the Nationality Act B.E. 2508 (1965). Where both parents are foreign, the child does not automatically acquire Thai nationality but is still issued a birth certificate. Foreign parents must separately report the birth to their home embassy (US Consular Report of Birth Abroad, UK Overseas Birth Registration, etc.) to secure the home-country citizenship and passport. Late registration after 15 days is allowed but attracts fines, and registration more than 6 months late typically requires a court order.

The 15-Day Deadline Under the Civil Registration Act

The Civil Registration Act B.E. 2534 (1991) (พระราชบัญญัติการทะเบียนราษฎร พ.ศ. 2534) governs all civil-status registrations in Thailand. Under Section 18, any birth occurring in Thailand must be reported to the Registrar (นายทะเบียน) at the Amphur covering the place of birth within 15 days. The duty falls on, in order: (1) the head of the household where the birth occurred; (2) the father or mother of the child; (3) the person designated by the household head; (4) the hospital director, where the birth was at a hospital.

In practice, the hospital handles the in-house notification and gives the parents the Notification of Birth (Tor Ror 1/1). The parents then walk it to the Amphur within the 15-day window. Failure to register attracts an administrative fine of up to THB 1,000 (Section 47) and complicates every subsequent step — schooling, passports, visa runs.

Documents Required at the Amphur

Foreign parents should arrive with originals and photocopies of:

Where the parents are unmarried and the father is foreign, the child takes the mother's surname by default. Recognition of paternity by the foreign father can be recorded at the Amphur under Section 1547 of the Civil and Commercial Code B.E. 2468 (1925), but legitimation generally requires the mother's consent and court endorsement.

The Registration Procedure Step-by-Step

The Amphur procedure is straightforward where paperwork is in order:

1. Queue at the Civil Registration counter (งานทะเบียนราษฎร). Most Amphurs handle births in the morning.
2. Hand over the Tor Ror 1/1. The registrar opens the file and asks who is the informant (ผู้แจ้งเกิด).
3. Confirm the child's name. Both Thai-script and Roman-script versions are recorded. Choose carefully — later changes to the Thai-script spelling require a separate procedure and small fee.
4. Confirm parents' details. Nationalities, passport numbers, and current address.
5. Sign the register. The informant signs the Civil Register; both parents sign if present.
6. Collect the Thai Birth Certificate (สูติบัตร / Tor Ror 19). Issued same day in most cases. Request two certified copies immediately — you will need them for the embassy.

Where one parent is Thai, the child is simultaneously entered on the Thai parent's Blue Tabian Baan with a Thai 13-digit ID number. Where both parents are foreign, the child can be entered on the foreigner-parent's Yellow Tabian Baan (Tor Ror 13), also receiving a 13-digit non-citizen ID.

Thai Nationality Acquisition Under the Nationality Act

The Nationality Act B.E. 2508 (1965) (as amended) governs Thai citizenship. The most relevant provisions are:

• Section 7(1): A child born to a Thai father or Thai mother acquires Thai nationality by birth, regardless of where born. Where the birth occurs in Thailand, this is automatic on registration.
• Section 7(2): A child born in Thailand to non-Thai parents acquires Thai nationality only if both parents are lawfully resident (i.e., hold Thai Permanent Residence). Children of foreign parents on visas (work permit, retirement, marriage) generally do not receive Thai nationality at birth.
• Section 7 bis: Children of stateless or illegal-status parents may receive Thai nationality only by specific Cabinet resolution, not automatically.

Children with one Thai parent therefore have dual nationality at birth — Thai plus the foreign parent's nationality (where that country also allows it; most Western countries do). Thailand does not require a choice at age of majority for dual nationals born this way.

Home-Country Reporting Through the Embassy

The Thai birth certificate alone does not give the child the foreign parent's citizenship — that requires a separate registration with the embassy. Foreign parents must report the birth to their consular service:

• United States: Consular Report of Birth Abroad (CRBA, Form FS-240) filed at the US Embassy in Bangkok or US Consulate Chiang Mai. CRBA + US passport application typically processed together. Requires evidence of the US parent's physical presence in the US.
• United Kingdom: Consular Birth Registration via the UK General Register Office, application through Bangkok. Optional but recommended — UK citizenship by descent is automatic where the parent is a British citizen otherwise than by descent.
• Australia / Canada / New Zealand / EU states: Each has its own consular procedure. Most require the Thai birth certificate (with MFA legalisation and certified translation), the parents' passports, and proof of the parent's citizenship.

Always order at least two MFA-legalised certified-translation sets of the Thai birth certificate at the start — one for the embassy and one for your own records.

Late Registration and the 6-Month Rule

Where the 15-day deadline is missed, late registration is still possible:

• Up to 6 months late: Administrative fine plus written explanation at the Amphur. Birth certificate still issued by the Amphur registrar.
• More than 6 months late: Under Section 19 of the Civil Registration Act and implementing regulations, the registrar typically refuses to register without a court order from the Juvenile and Family Court. This requires a petition, witness testimony (hospital records, family witnesses), and a court hearing.
• Births at home or outside a hospital: Require a notification from the village head (ผู้ใหญ่บ้าน) or community leader and at least two witnesses, in addition to the parents' identification.

Common Mistakes

Avoid these traps:

• Missing the 15-day window. Even a small overrun creates extra paperwork and risks the court-order route if it stretches past 6 months.
• Assuming the Thai birth certificate confers home-country citizenship. It does not — embassy registration is a separate procedure.
• Spelling the child's name carelessly in Thai script. Changing the Thai spelling later requires a separate Amphur procedure.
• Ignoring the Tabian Baan registration. Without the Thai 13-digit ID number, school enrolment and hospital records become painful.
• Forgetting MFA legalisation. Foreign embassies typically require the Thai birth certificate to be MFA-legalised and translated before they accept it.
• Unmarried fathers skipping legitimation. Without recorded paternity, the child has only the mother's surname and no inheritance rights from the father under Thai law.

FAQs

1. My baby was born in Thailand and I am the only foreign parent. Does my child get Thai nationality?

If the other parent is Thai, yes — automatically under Section 7(1) of the Nationality Act. If both parents are foreign (you and a foreign partner), no, unless both of you hold Thai Permanent Residence under Section 7(2).

2. Can I register the birth at any Amphur or must it be the one where the hospital is?

Registration is at the Amphur covering the place of birth. The hospital's address determines the Amphur. Subsequent change of registered address is then handled separately under Section 30.

3. What if we are not married — can the foreign father be named on the certificate?

Yes, but legitimation under Section 1547 of the Civil and Commercial Code requires the mother's consent. Without it, the child takes the mother's surname and the father appears only as the biological father, not as the legal father with parental rights.

4. How many certified copies of the birth certificate should we order?

Order at least two original certified copies at the Amphur (small fee per copy). One stays with your records; one goes to the foreign embassy. Additional copies can be ordered later but the original visit is cheapest.

5. Is the Thai birth certificate accepted internationally?

Yes, after MFA legalisation (Department of Consular Affairs, Chaeng Wattana) and certified Thai-to-English translation. Some countries additionally require an apostille — Thailand acceded to the Apostille Convention, simplifying this since 2024.
