Best Interests of the Child — Primary-Caregiver Presumption Under Age 7
Mother v Father — Custody Dispute
Composite summary — not a single reported case. This entry distils a settled line of Thai Supreme Court (Dika / ฎีกา) authority for legal education. It is not a transcript of one reported judgment, and the heading is not a citable case number. Do not cite it as specific case law — consult a Thai-qualified lawyer for the authoritative Dika number and current application.
Facts
On divorce or separation, parents disputed who should hold parental power (amnaj pokkrong) over young children. In typical reported cases the children were below 7 years of age and had been primarily cared for by one parent (frequently the mother). The other parent argued for equal or sole custody on the basis of greater earning capacity or better housing.
Legal Issue
How Thai courts weigh the best interests of the child and what weight the primary-caregiver relationship and the child's age have in custody decisions.
Holding
The Supreme Court has consistently held that the best interests of the child are paramount (Sections 1520 and 1566 CCC). For children under 7, courts give significant weight to maintaining the primary-caregiver relationship and to the stability of the child's existing environment, schooling, and emotional bonds. Financial superiority of the other parent does not by itself displace the presumption.
Reasoning
Section 1566 CCC and international standards (UNCRC) require child-centred decision-making. Empirical and policy considerations favour stability and continuity of care for young children. Economic resources are addressed through maintenance orders, not through transfer of custody.
Significance
Foundational doctrine in Thai family law and central to mixed-nationality custody disputes, which often involve allegations of asset disparity and forum-shopping.
Practical Takeaway
Mixed-nationality parents involved in cross-border custody disputes should not assume that financial advantage will secure custody of a young child in Thailand. The primary-caregiver record — daily care, school involvement, healthcare — is more persuasive.
