Child Support in Thailand

In Thailand, child support—legally referred to as "Maintenance" (Thai: Ka-Upakara-Liang-Du)—is governed by the Civil and Commercial Code (CCC). Unlike the mechanical formulas used in some Western jurisdictions, Thai law treats child support as a flexible, needs-based obligation.

As of 2026, the Thai legal system has become increasingly sophisticated in handling cross-border support claims, but the foundational principle remains the same: both parents are legally bound to support their children until they reach the age of majority (20 years old).

1. The Legal Foundation: Who Must Pay?

Under Section 1564 of the CCC, parents must provide maintenance and "proper education" during the child's minority. This obligation is absolute and cannot be waived by a private contract if such a waiver harms the child's welfare.

Marital vs. Non-Marital Children

The legal "trigger" for child support depends heavily on the parents' marital status at the time of birth:

  • Children of Married Parents: Support obligations are automatic. Even if the parents separate without a formal divorce, the duty to provide maintenance persists.

  • Children Born Out of Wedlock: Under Thai law, a child born to an unmarried woman is the legitimate child of the mother only. The biological father has no legal obligation to pay support—and conversely, no legal right to custody—until the child is "legitimated."

The "Legitimation" Hurdle

For a mother to claim support from an unmarried biological father, paternity must be legally established via:

  1. Subsequent Marriage: The parents marry each other.

  2. Voluntary Registration: The father registers his paternity at a local district office (Amphur), which requires the consent of the mother and the child.

  3. Court Judgment: If the father refuses, the mother (or the Public Prosecutor) must file a lawsuit to have him declared the legal father.

2. Calculation: How Much is "Enough"?

Thailand does not use a fixed percentage-of-income model. Instead, Section 1598/38 dictates that the amount is determined by:

  • The condition in life of the child: The lifestyle, education, and health needs the child had before the parents' separation.

  • The financial ability of the payer: The court examines the parent’s actual income, assets, and existing financial burdens (such as other children or elderly parents).

Common Factors in Court Decisions

FactorWhat the Court Examines
EducationPrivate school vs. public school; extracurricular activities.
HealthcareStandard of medical care and any chronic conditions.
Standard of LivingThe court aims to maintain the child's status quo whenever possible.
Parental IncomePayslips, tax returns, and even "lifestyle evidence" if a parent hides income.

3. The Two Paths to an Agreement

Path A: Mutual Consent (Administrative Divorce)

In an uncontested divorce at the Amphur, the parents sign a Divorce Agreement. This document must specify:

  • Which parent will pay.

  • The exact amount and frequency (e.g., 15,000 THB per month).

  • The method of payment (direct bank transfer is highly recommended). Once registered, this agreement has the force of law.

Path B: Court Order (Contested Divorce or Legitimation)

If the parents cannot agree, the Central Juvenile and Family Court intervenes. The court process often involves an investigation by the Observation and Protection Centre, where officials interview both parents to assess their living conditions and the child's needs.

4. Enforcement: What if They Don’t Pay?

Enforcement remains the most challenging aspect of child support in Thailand, particularly when the paying parent is a foreign national or works in the "informal" economy.

Legal Remedies

  1. Wage Garnishment: The court can order an employer to deduct support directly from a salary. This is effective for civil servants or employees of large, registered companies.

  2. Asset Seizure: If payments are in arrears, the court can authorize the seizure and public auction of the debtor's property (land, cars, or bank accounts).

  3. Contempt of Court: While rarely leading to jail time for debt alone, persistent refusal to follow a court order can lead to a "Contempt of Court" charge.

Crucial Note for 2026: Thailand is increasingly cooperative with international agencies. For parents residing abroad, enforcement may be pursued via international legal cooperation treaties, though this process is notoriously slow and expensive.

5. Modifications and Special Circumstances

Child support is never "set in stone." Under Section 1598/39, either parent can petition the court to increase or decrease the amount if:

  • The Payer’s income changes: For example, due to a promotion or job loss.

  • The Child’s needs change: For example, entering university or developing a medical condition.

  • Cost of Living: Significant inflation or changes in the Thai economy.

Post-Majority Support

The obligation generally ends at 20. However, if the child is infirm or disabled and unable to earn a living, the parents may be ordered to continue support indefinitely.

6. Summary Checklist for Parents

If you are seeking child support in Thailand, ensure you have the following:

  • The Child's Birth Certificate: Original and a certified copy.

  • Paternity Evidence: Marriage certificate or proof of legitimation.

  • Financial Records: At least 6 months of bank statements and proof of the child's school fees/medical bills.

  • A Detailed Budget: A clear breakdown of the monthly cost of raising the child.

Navigating child support requires a balance of legal precision and a focus on the child's best interests. Because Thai judges have broad discretion, presenting a well-documented case regarding the child's actual needs is often more effective than simply demanding a high percentage of the other parent's income.
