Thai civil registration documents — 6 cases

A birth in Thailand is notified at the registration office covering the place of birth, supported by the hospital's certificate of birth (Thor Ror 1/1). The registrar records the entry in the birth register and issues the birth certificate, which is the state document foreign authorities accept. A hospital certificate alone is usually not sufficient for visa or civil-status filings.

If the original is lost or damaged, request a registrar-certified extract of the birth register from the office where the birth was notified. A copy signed by the registrar can be used in place of the original for legalisation; a self-made photocopy without the registrar's signature will not pass consular legalisation.

The house registration shows the house code, the address and the persons registered there with their status as householder or occupant. For overseas use, receivers usually want a registrar-certified copy of the page listing the applicant and the page showing the address — not always the whole book.

Foreign nationals lawfully resident but without Thai nationality are recorded in a Thor Ror 13 book. Say so when ordering a translation: its headings and fields differ from the Thor Ror 14.

The card shows the given name, surname, date of birth, registered address and the 13-digit identification number; the reverse carries a production control code that some receivers also want translated, so scan both sides before ordering.

Where the receiver wants a paper document issued by the state rather than a plastic card, request a certificate of card particulars from the registration office. It is easier to handle in legalisation because it can be copy-certified and translated directly.

When a person changes a given name or surname, the registrar issues a change-of-given-name certificate (form Chor 3) or a change-of-surname certificate (form Chor 5). It is the only document proving that the old and new names belong to the same person, which makes it critical in cross-border files.

The common problem is older documents — birth certificate, degree, employment letter, marriage record — still bearing the former name while the passport and current papers show the new one. Without the change-of-name certificate and its translation, the receiver may treat the file as inconsistent and refuse it.

On a death, the person responsible must notify the registrar within the period set by the Civil Registration Act B.E. 2534. Where the death occurred in a healthcare facility, the facility's certificate of death (Thor Ror 4/1) supports the notification, and the registrar then issues the death certificate accepted by authorities at home and abroad.

For an unnatural death the law requires an inquest first, which can generate further documents from the investigating officer or the examining physician. Insurers and foreign courts sometimes request those alongside the death certificate.

A single-status or marital-status certificate is issued by the registration office from the civil and family registration databases. It is commonly required to marry abroad, for spouse-visa files, and in cross-border family proceedings.

A certificate of civil-registration particulars confirms entries such as address, date of birth or family relationships. It suits receivers that want an official letter rather than a copy of a house registration page.
