When parents are not legally married, a child is automatically considered the legitimate child of the mother under Thai law. A father who wishes to obtain legal paternal status may complete a child legitimation process.
Legitimation establishes a legal relationship between father and child, including rights relating to surname, parental responsibilities, inheritance rights, and supporting applications for nationality or visas in Thailand.
The process depends on the age of the child:
- Age 7 or older: Registration can be completed directly at the District Office.
- Under 7 years old: A court order is required before registration at the District Office
⚖️ Court process in the case of the child under 7 years old.
After filing the petition, parties are usually required to attend an appointment with an officer to verify the father-child relationship.
Typical attendees include:
- Father
- Mother
- Child
- At least one witness
- Interpreter (if either parent is a foreign national)

👨👧 Why Legitimation Matters for Foreign Fathers
If you have a child in Thailand but are not legally married to the mother, you are not automatically recognized as the legal father under Thai law. Legitimation is necessary to establish your legal parental rights.
This process is important if you wish to:
- Be legally recognized as the father
- Apply for your child’s nationality abroad
- Apply for a Thai visa based on supporting your child
- Secure inheritance rights and parental authority
