Quick Facts
Child support in Thailand at a glance
Section 1
How Child Support Amounts Are Determined
Thai law has no fixed formula. Courts assess the child's needs alongside the paying parent's financial capacity. The quality of the evidence presented on both sides directly affects the outcome.
Child's current monthly expenses
Schools fees, tutoring, transport, food, clothing, medical, extracurricular activities. Courts expect itemised evidence, not estimates.
Standard of living before separation
The child's pre-separation lifestyle is a reference point. Courts do not automatically reduce the child's standard of living because parents have separated.
Paying parent's income and assets
Employment income, business income, rental income and overseas income are all considered. Asset ownership is also relevant — a parent who claims low income but holds significant property attracts scrutiny.
Receiving parent's income and capacity
Where the receiving parent has substantial income, this may reduce the paying parent's obligation proportionally. Both parents' financial positions are assessed.
Section 2
Agreed Arrangements vs Court Orders
Agreed arrangement — District Office
Where parents agree, the child support amount can be documented and registered at the District Office as part of divorce proceedings. This is legally binding and enforceable without further court action. Always include a variation mechanism — circumstances change.
Court order — Family Court
Where parents cannot agree, the Family Court issues an order following a hearing. The court assesses evidence from both sides and sets an amount. A court order enables direct enforcement action — salary garnishment, bank attachment, asset seizure — without further proceedings.
An informal agreement — not registered at the District Office or issued by the court — is unenforceable under Thai law. When the paying parent defaults, there is no legal instrument to enforce. Always formalise the arrangement regardless of how cooperative relations currently are.
Section 3
Enforcement in Thailand
Salary garnishment
Where the paying parent is employed in Thailand, the court can order the employer to deduct child support directly from the monthly salary and transfer it to the receiving parent. This is the most reliable domestic enforcement mechanism.
Bank account attachment
The court can freeze and draw from the paying parent's Thai bank accounts. This requires knowing which bank the paying parent uses — asset disclosure during proceedings is important.
Asset seizure and sale
Where a paying parent owns property or vehicles in Thailand and has defaulted on payments, the court can order seizure and forced sale to satisfy arrears.
Contempt proceedings
A parent who wilfully fails to comply with a court order is in contempt of court. This can result in fines and, in persistent cases, imprisonment.
Section 4
When the Paying Parent Is Abroad
The legal obligation does not end when a parent leaves Thailand. Enforcement abroad requires the right legal instrument and country- specific steps.
Obtain a Thai court order first
A Thai Family Court order is the legal instrument needed to pursue enforcement abroad. Informal agreements and District Office registrations are harder to enforce internationally — a formal court order is the correct starting document.
Identify whether the foreign country has a reciprocal arrangement
Thailand has bilateral legal cooperation agreements with a number of countries. Whether a Thai order can be directly registered abroad depends on the receiving country's laws on foreign judgments.
Engage correspondent lawyers in the foreign jurisdiction
Enforcement in another country requires a lawyer admitted in that jurisdiction. We coordinate with correspondent lawyers in the UK, Australia, the US, Germany and Scandinavia, among others.
Register or re-litigate in the foreign court
Some countries allow direct registration of a foreign maintenance order. Others require fresh proceedings in their own courts. The approach depends entirely on the foreign jurisdiction.
Common Mistakes
Five errors that create problems
Agreeing child support informally without documentation
Informal agreements — even between cooperative parents — are unenforceable under Thai law. When the paying parent later reduces or stops payment, there is no court order to enforce. An agreed amount should always be documented and registered at the District Office or formalised through the Family Court.
Assuming the obligation ends when a parent leaves Thailand
The legal obligation to support a child does not end when a parent leaves Thailand. The obligation runs until the child reaches 20. A parent who stops paying because they have relocated abroad remains in breach of a Thai court order and can face enforcement in their new country of residence.
Not establishing paternity before pursuing child support from an unmarried father
An unmarried father has no legal obligation to pay child support until paternity is legally established through legitimation or a court ruling on parentage. A support claim against an unmarried father must begin with, or be accompanied by, a paternity application.
Accepting a lump sum payment without court approval
Some parents agree a one-off lump sum instead of monthly payments. Without court approval, this arrangement is informal and the paying parent could later claim they still owe monthly payments. Any lump-sum capitalisation of future child support should be approved by the Family Court.
Failing to document the child's expenses before applying for a court order
Courts determine child support based on evidence of the child's actual needs. Applications that lack itemised monthly expense records, school fee invoices and medical costs receive lower awards than applications backed by documentation. Preparation matters significantly to the outcome.
Questions & Answers
Common questions about child support in Thailand
The father of my child has never been on the birth certificate — can I still claim child support?
You can, but paternity must first be established. If the father has not registered legitimation at the District Office, you will need to apply to the Family Court for a paternity ruling alongside the child support claim. DNA evidence is typically required. Once paternity is established by court order, the support obligation is backdated to the date of the application.
My ex-husband has left Thailand and stopped paying. What can I actually do?
Start with a Thai court order if you do not already have one — this is the enforceable document. Once you have a court order, enforcement abroad depends on the country. For the UK, Australia and several European countries, we coordinate with correspondent lawyers to register or re-litigate the Thai order in the foreign court. For countries with no reciprocal arrangement, the options are more limited but not exhausted — assets retained in Thailand can still be enforced against.
My income has fallen significantly. Can I apply to reduce the child support I am paying?
Yes. Either parent can apply to the Family Court to vary an existing child support order where there has been a material change in circumstances. A genuine, documented reduction in income is the most common ground. You will need to evidence the change — tax returns, employment termination documents or business accounts. Courts do not reduce support on the basis of verbal claims.
We have agreed an amount between ourselves — do we need to go to court?
You do not need to go to court if both parents agree, but you should document the arrangement formally. The fastest route is to register the agreed amount at the District Office as part of divorce documentation. This makes it legally binding and enforceable without returning to court. An unregistered informal agreement cannot be enforced if the paying parent later defaults.
My child is over 18 and studying at university — does child support continue?
Under Thai law the obligation runs until age 20, regardless of whether the child is studying or working. It does not automatically extend beyond 20 for full-time students. If the child reaches 20 and the paying parent stops payment, there is no legal basis to compel continued support through child support law — though other arrangements can be made voluntarily or through an adult dependency claim in some circumstances.
