Child Legitimation in Thailand

Child legitimation is a legal process that confirms the status of a child born out of wedlock, granting them the same legal rights and privileges as children born within a marriage. In Thailand, the process of legitimating a child involves specific legal procedures outlined in the Civil and Commercial Code. This comprehensive guide explores the key aspects of child legitimation in Thailand, the legal rights it confers, and the cultural considerations that may come into play.

Legal Framework for Child Legitimation:

  1. Thai Civil and Commercial Code:
    • The legal provisions for child legitimation in Thailand are primarily governed by the Thai Civil and Commercial Code, specifically Sections 1535 to 1540. These sections outline the procedures for legitimating a child born out of wedlock.
  2. Rights and Privileges:
    • Legitimation provides the child with the same legal rights and privileges as a child born within a legal marriage. This includes inheritance rights, the right to use the father’s surname, and the right to receive financial support.

Procedures for Child Legitimation:

  1. Voluntary Acknowledgment:
    • The father of the child can voluntarily acknowledge paternity by signing an acknowledgment of paternity at the district office or amphur. Both parents must be present, and the acknowledgment is then recorded in the child’s birth register.
  2. Court Order:
    • If the father is unwilling or unable to acknowledge paternity, the mother or any interested party can file a petition with the court seeking a legitimation order. The court may order a blood test or use other evidence to establish paternity.
  3. Consent of the Mother:
    • Legitimation requires the consent of the mother, and both parents must agree to the legitimation process. If the mother is deceased, the legitimation process may still proceed with the consent of her legal heirs.

Effect of Legitimation on the Child:

  1. Inheritance Rights:
    • Legitimated children have equal inheritance rights as children born within a legal marriage. They are entitled to inherit from both parents and other legal heirs.
  2. Use of Father’s Surname:
    • Upon legitimation, the child has the right to use the father’s surname. This reflects the legal recognition of the paternal relationship.
  3. Financial Support:
    • Legitimated children are entitled to financial support from both parents. The court may determine the amount of support based on the financial capabilities of the parents and the needs of the child.

Cultural Considerations:

  1. Stigma and Social Perception:
    • In Thai culture, social perceptions regarding legitimacy may influence the decision to legitimize a child born out of wedlock. Legitimation can help mitigate potential stigma and promote social acceptance.
  2. Extended Family Dynamics:
    • The role of extended family members in Thai culture is significant. Family elders may play a role in advising or influencing decisions related to child legitimation, emphasizing the importance of family harmony.

Challenges in Child Legitimation:

  1. Parental Consent:
    • If the parents do not agree on legitimation, the process may be delayed or become more complicated. Court intervention may be necessary to resolve disputes and establish paternity.
  2. Deceased Parent:
    • If one parent is deceased, obtaining consent may involve dealing with legal heirs and navigating additional complexities. It may require cooperation from the deceased parent’s family.

Seeking Legal Assistance:

  1. Engaging Family Law Professionals:
    • Given the legal and cultural nuances involved, engaging legal professionals with expertise in Thai family law is advisable. They can guide parents through the legitimation process, ensure compliance with legal requirements, and address any challenges that may arise.
  2. Cultural Sensitivity:
    • Legal professionals should approach child legitimation cases with cultural sensitivity, recognizing the potential impact on family dynamics and societal perceptions. Mediation and communication skills become crucial in navigating complex family situations.


Child legitimation in Thailand is a legal process that holds cultural, legal, and personal significance. By understanding the legal frameworks, navigating the procedures outlined in the Civil and Commercial Code, and seeking legal assistance when needed, parents can ensure that their child receives the same legal rights and privileges as those born within a legal marriage. The process not only addresses legal rights but also contributes to the social acceptance and integration of the child into the broader family and community. In embracing child legitimation, Thailand continues to evolve its legal landscape to reflect the changing dynamics of contemporary family structures.
