Child Legitimation in Thailand

Child legitimation is a legal process that establishes the legal relationship between a father and a child born out of wedlock. In Thailand, legitimating a child involves specific legal procedures to grant the child the same rights as those born within a marriage. This comprehensive guide explores the legal framework for child legitimation in Thailand, the significance of the process, the steps involved, and the cultural context surrounding legitimation.

Legal Framework for Child Legitimation in Thailand:

  1. Civil and Commercial Code:

    Child legitimation in Thailand is governed by the Civil and Commercial Code. Sections 1548 to 1552 of the code outline the legal procedures and requirements for legitimating a child born out of wedlock.

  2. Significance of Legitimation:

    Legitimation bestows legal recognition on the relationship between the father and the child. Once legitimized, the child has the same legal rights as children born within a marriage, including inheritance rights, the right to use the father’s surname, and other legal benefits.

Conditions and Procedures for Child Legitimation:

  1. Voluntary Acknowledgment:

    Legitimation can occur through the voluntary acknowledgment of paternity by the father. Both parents can jointly file an application for legitimation at the local district office or amphur.

  2. Consent of the Mother:

    The mother’s consent is a crucial element in the legitimation process. If the mother is deceased or unable to provide consent, the court may consider other evidence, such as a written acknowledgment of paternity.

  3. Voluntary Submission to the Court:

    In cases where the mother does not provide consent, the father can submit a request to the court for legitimation. The court will then consider the evidence presented and decide whether legitimation is in the best interests of the child.

  4. Establishing Paternity:

    The father must establish his paternity through evidence such as DNA testing, witness testimonies, or any other relevant documentation that supports the claim of biological fatherhood.

  5. Consent of the Legitimated Child (if applicable):

    If the child is at least seven years old, their consent to the legitimation process may be required. The child’s opinion is considered by the court in determining whether legitimation is in their best interests.

Cultural Considerations in Child Legitimation:

  1. Social Stigma:

    While attitudes toward children born out of wedlock are evolving, there may still be lingering social stigma. Child legitimation can help reduce any stigma associated with the child’s parentage.

  2. Family Harmony:

    Legitimation can contribute to family harmony by formalizing the legal relationship between the father and the child. This may be particularly important in cultures that place high value on family unity.

  3. Parental Recognition:

    For fathers, legitimation is not only a legal process but also a symbolic act of recognizing and acknowledging their parental responsibility. This can have positive effects on the child’s sense of identity and self-worth.

Rights Conferred by Legitimation:

  1. Inheritance Rights:

    Legitimated children have the same inheritance rights as those born within a marriage. They are entitled to inherit from both parents and other relatives according to Thai inheritance laws.

  2. Use of Father’s Surname:

    Legitimated children have the right to use the father’s surname, providing them with the same naming rights as children born within a marriage.

  3. Legal Benefits and Obligations:

    Legitimated children are entitled to the same legal benefits and obligations as children born within a marriage. This includes rights related to support, custody, and other legal considerations.

Seeking Legal Assistance:

  1. Engaging a Family Lawyer:

    Given the legal intricacies of child legitimation, engaging a family lawyer with expertise in Thai family law is advisable. A legal professional can guide parents through the process, ensure compliance with legal requirements, and represent their interests.

  2. Understanding Legal Rights:

    Both parents should have a clear understanding of their legal rights and responsibilities throughout the child legitimation process. Legal professionals can provide clarity on the legal implications of legitimation.


Child legitimation in Thailand is a legal process that carries both legal and cultural significance. It formalizes the legal relationship between a father and a child born out of wedlock, providing the child with the same rights and privileges as those born within a marriage. While the legal framework outlines the conditions and procedures for legitimation, cultural considerations add depth to the process, addressing societal attitudes, family harmony, and parental recognition. Seeking legal assistance ensures that parents navigate the legitimation process effectively, fostering a legal foundation that contributes to the well-being and identity of the child. Ultimately, child legitimation in Thailand serves as a means to uphold the rights of the child, acknowledge parental responsibilities, and create a legal framework that reflects the evolving dynamics of family structures.
