What Civil Registration Covers in Thailand

Under Thailand’s Civil Registration Act (B.E. 2534), the system records major life events and personal status changes. These include:

Birth registration – recording a child’s birth and issuing a birth certificate.
Marriage registration – formal recognition of a legal marriage between parties.
Divorce registration – documenting dissolution of a marriage and updating civil records.
Death registration – recording the death of an individual and issuing official certificate.
Household and address updates – changes in residence, household composition or status must also be lodged under the Act.

Why Proper Registration Matters

Legal recognition – Without correctly recorded registration, rights and benefits (inheritance, social security, government documentation) may face obstacles.
Foreign involvement – Especially for non-Thai nationals, correct registration ensures legal clarity for marriages, familial status and subsequent immigration or estate-planning implications.
Government records & compliance – The registrar offices under provincial, district and local government manage the registry; errors or omissions may delay processing or cause complications.
Documentation accuracy – Certificates, name spellings, translations and formal attestations all must be handled correctly to avoid legal or administrative issues.

How BASE Law Firm Assists You

Initial review & assessment
We begin by reviewing your personal status and civil registration needs: birth/marriage/divorce/death or household change. We identify the specific registration category and required documents.

Documentation & submission support
Our team prepares or reviews:

Application forms for registration or amendment
Original and translated supporting documents (passports, ID cards, previous certificates)
Power of attorney when required
Liaison with the relevant registration office to submit forms and monitor progress

Amendments, corrections & international support
If registration needs correction (e.g., name change, error in record) or involves foreign nationals (marriage to Thai spouse, foreign-born children), we manage the process of modification, translation/legalisation, and coordinate with consular or embassy requirements.

Post-registration follow-up
Once the registration is processed, we ensure you receive the correct certificate(s), that they are properly authenticated (if needed abroad) and advise you on any related obligations (e.g., household registration changes, immigration implications).

How We Work

Consultation & fact-gathering
We begin by discussing your registration requirement, your status (Thai or foreign) and your intended use of the certificate (local use, immigration, inheritance).

Strategy & documentation plan
We develop a roadmap of required forms, supporting documents, translations/legalisation if needed, timing and submission path (district office, foreign embassy, etc.).

Submission & representation
We assist in completing the forms, filing at the appropriate registrar, and monitor the case until the certificate is issued correctly.

Post-issuance support
After registration, we help you obtain authenticated copies, advise on linking the registration to immigration or asset/documentation matters, and remain available for any required updates or amendments.
