Standing, amount, duration, retrospective claims, and enforcement
When parents separate or one parent does not contribute to a child’s expenses, the central issue is rarely limited to the monthly amount. Other questions include who may bring the claim, what must be proved, whether earlier expenses can be recovered, and how an award can be enforced if payment is not made.
Thai law requires both parents to maintain and educate their minor child. The amount and method of payment are assessed by balancing the child’s reasonable needs against the means, income, and circumstances of the person under the duty. There is no uniform tariff applicable to every family.
This article answers ten practical questions from preparation through enforcement. It is intended to help readers organize the facts and evidence; the outcome of an individual case will depend on its pleadings, evidence, and particular circumstances.
- What expenses does child maintenance cover?
Section 1564 of the thai civil and commercial code requires parents to maintain and provide an appropriate education for a child during minority. Maintenance is therefore not confined to food. It extends to expenses reasonably required for the child’s living conditions and development, having regard to the family’s circumstances.
Relevant items commonly include:
- Food, housing, clothing, and ordinary daily expenses;
- Tuition, books, educational materials, transport, and appropriate activities;
- Medical care, health insurance, medication, and special-needs expenditure; and
- Necessary childcare or caregiving and other costs connected with the child’s welfare.
The court considers the reasonableness of each component, not merely the total claimed. A claimant should therefore show the amount, frequency, purpose, and supporting payment evidence or a verifiable estimate.
- Who may bring the claim?
Section 1562 generally prevents a descendant from suing an ascendant in a civil or criminal case, a restriction commonly known as the rule against an ‘utlum’ action. Section 1565 nevertheless provides a specific route for child maintenance: in addition to a public prosecutor bringing the proceeding, either parent may bring it.
Where the child lives with one parent, that parent commonly conducts the case for the child’s benefit. If legal paternity must also be established, the child’s legal status and the relief sought must be pleaded consistently. The proper claimant and cause of action should not be inferred solely from the day-to-day caregiving arrangement.
- Can maintenance be claimed from a father if the parents were not married?
Under section 1546, a child born to persons who are not married to each other is the legitimate child of the mother. Under section 1547, legal paternity may arise through the parents’ subsequent marriage, registration of legitimation by the father, or a court judgment declaring the child legitimate.
If the man has not yet become the legal father, a claim for a declaration of paternity and child maintenance may, where the statutory conditions and facts permit, be brought in the same proceeding. Relevant evidence may include the birth certificate, the parties’ relationship history, acknowledgment or holding out as the father, earlier financial support, communications, witnesses, and genetic testing where paternity is disputed.
The man’s name on a birth certificate, factual acknowledgment, or voluntary support may be important evidence, but should not automatically be treated as completing legal legitimation in every case. Registration status and any relevant order or judgment must be checked.
- What are the usual procedural steps?
- Collect documents establishing the child’s relationship and legal status, including the birth certificate, household registration, legitimation record, or relevant judgment.
- Prepare a child-expense schedule separating recurring, annual, and exceptional items, supported by documents.
- Gather available information on both parents’ means, including income, assets, liabilities, and dependants.
- Define the relief precisely: instalment amount, commencement date, exceptional expenses, and payment method.
- File in the juvenile and family court with jurisdiction and proceed through mediation or adjudication as directed by the court.
Family proceedings focus on the child’s welfare and best interests, making mediation important. Any settlement should nevertheless be clear and enforceable. It should specify payment dates, the receiving account, treatment of exceptional expenses, and the consequences of default.
No reliable standard duration can be promised. Timing depends on service, negotiations, witnesses, disputed paternity, requests for income records, and the court’s calendar. A timetable from another case should not be treated as a guarantee.
- How does the court determine the amount?
Section 1598/38 directs attention to the means of the person under the duty, the recipient’s circumstances, and the facts of the case. There is therefore no universal minimum or maximum. Awards may differ even for children of similar age where income, education, health, or family obligations differ.
Evidence commonly relevant to the assessment includes:
- Salary, business income, bonuses, dividends, rent, and assets indicating capacity to pay;
- The child’s present needs and foreseeable annual expenses, such as school fees;
- Financial and non-financial care already provided by each parent, including caregiving time; and
- Necessary liabilities and dependants of the paying parent, distinguished from voluntary spending or arrangements designed to suppress apparent income.
A monthly budget should be supported and annual costs averaged without double counting. If the other parent’s financial records are unavailable, the claimant should identify what is known and seek appropriate court-assisted production through the applicable procedure.
- How long does the duty continue?
As a general rule, section 1564 applies while the child remains a minor, ending when the child reaches majority under law, whether by reaching the statutory age or by a legally valid marriage.
For an adult child, the statutory duty continues only where the child is disabled and unable to earn a living. University attendance after majority does not automatically extend section 1564, although the parties may agree to support the child until graduation. Such an agreement should define the education level, maximum period, and termination events.
- May maintenance be paid as a single lump sum?
Section 1598/40 provides for payment in periodic monetary instalments as the default. A different method may be used by agreement or, absent agreement, where special circumstances exist and the court considers another form appropriate. A lump sum is therefore exceptional, but not absolutely prohibited.
Before accepting a lump sum, the parties should assess the remaining support period, inflation, future education and medical costs, the risk of premature depletion, and safeguards for the child’s benefit. A blended arrangement may combine monthly payments with an education account or reimbursement of exceptional expenses against receipts.
The right to maintenance is personal. Section 1598/41 provides that it cannot be waived or transferred and is not subject to execution. Any settlement should protect the child’s interests and avoid an overbroad purported waiver of future rights.
- Can maintenance or earlier expenses be claimed retrospectively?
The phrase ‘retrospective maintenance’ may describe distinct claims: (1) the child’s maintenance for the future or for a period before judgment, (2) instalments already due under an enforceable judgment or agreement, and (3) a contribution claim by the parent who alone paid the child’s expenses against the other parent.
The commencement date and limitation analysis may differ according to the legal basis, pleaded relief, and facts. Supreme court judgment no. 2697/2548, often cited for a five-year period, concerned a claim between parents after one parent alone had paid maintenance. It should not be reduced to a rule that every maintenance case invariably permits five years of retrospective recovery.
The claimant should retain payment evidence from the date of separation, including school invoices, bank statements, medical expenses, and proof of non-payment or partial payment. The pleading should identify whose right is asserted, the relevant period, and the calculation method.
- Can the amount be increased or reduced later?
Under section 1598/39, the court may cancel, reduce, increase, or reinstate maintenance where the parties’ circumstances, income, or financial position have changed. The change should be material and supported by evidence, not merely dissatisfaction with the existing amount.
Examples include a new educational stage, illness or special needs, a substantial increase in the child’s expenses, a genuine increase or reduction in the payer’s income, loss of earning capacity, or a change in caregiving responsibilities.
A payer should not unilaterally reduce or stop payments. If the existing amount appears in a judgment or a court-approved compromise, an application for variation should be made and the existing order followed unless and until the court orders otherwise.
- What happens if an award is not paid?
A judgment creditor may seek execution against attachable property and claims of the judgment debtor under thai civil procedure, including, where legally available, bank accounts, income, securities, vehicles, or real estate. The applicable exemptions and the legal execution department’s procedures must be checked for the specific asset.
Section 162 of the juvenile and family court and procedure act b.e. 2553 (2010) permits the court to order payment into court. Where the debtor has regular income, the court may direct attachment of the monthly amount and require the person responsible for paying that income to remit it to the court. Non-compliance may lead the court to summon, question, and warn the debtor.
If the debtor then disobeys the warning without reasonable cause, the court may issue an arrest warrant and order detention until payment or deposit. Each period of detention may not exceed fifteen days unless temporary release is granted. This enforcement measure does not extinguish the maintenance debt.
Court fees and other costs
Section 155 of the juvenile and family court and procedure act exempts the filing of claims or applications, and procedural acts in family cases seeking maintenance or alimony, from court filing fees and litigation costs.
This does not mean that every expense is eliminated. Depending on the case, there may still be legal fees, translation or certification costs, travel expenses, genetic-testing costs, or expenses associated with asset investigation and execution. The scope of work and fee basis should be confirmed before counsel or another service provider is engaged.
Evidence checklist
- Birth certificate, household registration, identification documents, and proof of legal parentage;
- Judgments, marriage or divorce records, parental-power arrangements, and relevant court compromises;
- A child-expense schedule supported by receipts, school invoices, medical records, and bank statements;
- Available evidence of both parents’ income and assets, such as payslips, income certificates, financial statements, or business records;
- Demands and communications, payment history, and evidence of default; and
- Evidence of special needs and witnesses able to explain the actual caregiving arrangement.
Evidence should be chronological and tied to the amount claimed. A large bundle of receipts is less useful if relevance, calculation, and duplicate items are not explained.
Conclusion
A child-maintenance claim gives practical effect to the parents’ shared legal duty. Its purpose is not to punish either parent, but to allocate responsibility fairly according to the child’s needs and each parent’s means.
A well-prepared case should explain the parties’ legal status, the child’s actual expenses, each parent’s capacity, the requested amount and method of payment, and the treatment of exceptional expenses and future changes.
Where paternity is disputed, income is difficult to trace, overseas assets are involved, the amount is substantial, or an existing judgment is in default, the documents and litigation strategy should be reviewed before filing so that the relief is legally sound and practically enforceable.
