Divorce & Child Custody.

Divorce in Thailand can be straightforward where both spouses agree on every major issue. It can also become highly complex where there are disputes concerning children, parental power, custody, international relocation, property, debts, maintenance, foreign assets, domestic violence or recognition of the divorce in another country.

Where children are involved, the end of the relationship does not end the responsibilities of parenthood. Questions about divorce, parental power and child custody must therefore be considered separately but together.

Divorce in Thailand

Divorce Routes

Thai law provides different routes to divorce depending upon the circumstances. Broadly, a divorce may be registered by mutual consent, or obtained through the court where agreement is not possible and a legally recognised ground for divorce exists. The correct route depends upon the marriage, the parties' circumstances and whether they agree on the consequences of separation.

Divorce by Mutual Consent

Where both spouses agree to divorce, a registered divorce may be possible through the civil-registration system. This will normally require both parties to agree to the divorce and complete the required registration process.

Before signing a divorce agreement, clarify:

• division of property;
• debts;
• maintenance;
• child custody and parental power;
• child support;
• residence of children;
• international travel authority;
• contact arrangements; and
• any other continuing obligations.

Court Divorce

Where one spouse will not agree to divorce, a court application may be required. Thai law provides statutory grounds upon which one spouse may seek a divorce. The applicable ground depends upon the facts.

A court case may involve evidence concerning matters such as:

• adultery;
• serious misconduct;
• abandonment;
• separation;
• failure to provide support;
• violence;
• serious harm;
• disappearance;
• breach of marital obligations; or
• other legally recognised grounds.

International and Foreign Divorce

Foreigners Can Divorce in Thailand

Foreign nationals can be involved in divorce proceedings in Thailand where the Thai courts or registration system have jurisdiction. This can include Thai-foreign marriages, foreign-foreign marriages connected with Thailand, marriages registered in Thailand and some marriages registered abroad.

However, jurisdiction and recognition can become complicated. A divorce that is valid in Thailand may still need to be recognised or registered in another country. Foreign nationals should therefore consider both:

For detailed guidance on foreign divorce recognition, see the Foreign Divorce in Thailand guide.

Foreign Marriage Certificates

Where the marriage was registered outside Thailand, the foreign marriage certificate may need to be legalised, authenticated, translated into Thai and accepted as evidence before it can be used in Thai proceedings or administrative processes. Do not assume that an untranslated foreign marriage certificate will automatically be sufficient.

Property on Divorce

Two Categories of Property

Divorce can involve two broad categories of property under Thai matrimonial law. The distinction is important because not every asset owned by either spouse is automatically divided in the same way.

Keep Financial Records

Where divorce is likely, preserve evidence relating to:

• land;
• condominiums;
• bank accounts;
• investments;
• companies;
• vehicles;
• loans;
• mortgages;
• credit agreements;
• overseas assets;
• tax records;
• insurance;
• pension interests; and
• major transfers.

Do not destroy or hide records. If there is a dispute concerning ownership, the documentary history may become crucial.

Foreigners and Thai Land After Divorce

Marriage to a Thai national does not give a foreign spouse unrestricted land-ownership rights. Divorce does not change those restrictions. Where Thai land is registered in the Thai spouse's name, the foreign spouse should not assume that financial contribution automatically means legal ownership of the land. Property claims need to be analysed using the actual ownership structure, evidence and applicable law.

Houses Built on Thai Land

A house and the land beneath it may involve separate legal questions. A foreign spouse may have paid substantial money to construct a house on land owned by the Thai spouse. That does not automatically establish ownership of the underlying land. Important questions may include:

• who owns the land;
• who owns the building;
• whether a superficies, lease or other right exists;
• who paid construction costs;
• what documents exist;
• what was agreed between the spouses; and
• what remedies may be available.

Do not assume that paying for construction guarantees a right to remain indefinitely.

Debts on Divorce

Not every debt incurred by one spouse is automatically treated identically. Relevant questions may include:

• when the debt was incurred;
• why it was incurred;
• whether both spouses agreed;
• whether it benefited the household;
• whether both names appear on the agreement;
• whether either spouse acted as guarantor; and
• whether the debt relates to marital property.

Do not sign new guarantees or transfers simply to "make the divorce easier" without understanding the consequences.

Spousal Maintenance

Maintenance between spouses may become relevant in some divorce cases. The availability and amount of maintenance depend upon the circumstances and legal basis. Do not assume that maintenance is automatically payable in every divorce, nor that the financially stronger spouse has no potential obligation simply because property has been divided.

Children After Separation

Children Are Not Part of the Property Settlement

What Is Parental Power?

Thai family law uses the concept of parental power. This refers to legal authority and responsibility concerning a child. It can affect important decisions about where the child lives, education, medical treatment, legal representation, property belonging to the child, travel and other major decisions.

Custody and Residence

In ordinary language, parents often use "custody" to mean "who does the child live with?" Legally, the position can be more nuanced. The precise arrangement depends upon the parents' marital status, agreements, registration, court orders, legitimation, the child's circumstances and any safety concerns.

Agreed Child Arrangements

Where both parents agree, arrangements concerning children can potentially be recorded as part of the divorce process. The agreement should be clear. Important matters may include:

• where the child will live;
• which parent holds parental power;
• contact with the other parent;
• school decisions;
• healthcare;
• financial support;
• holiday arrangements;
• travel abroad; and
• passports.

Vague wording can create problems later.

Court Custody Disputes

Where parents cannot agree, the court may need to determine the appropriate arrangement. The court will consider the child's welfare and the facts of the case. Relevant evidence can include:

• existing care arrangements;
• stability;
• schooling;
• home environment;
• each parent's involvement;
• safety;
• violence;
• neglect;
• substance misuse;
• practical ability to care for the child; and
• the child's circumstances generally.

Do not assume that one parent automatically wins because of sex, nationality or income alone. The actual legal position must be established.

Unmarried Parents, Legitimation and Child Support

Unmarried Parents

Where the parents were never legally married, the position can differ. The mother will generally have a different legal position from the unmarried father. For an unmarried father, legitimation can be critically important. A biological relationship alone should not be assumed to establish every aspect of parental power automatically.

Legitimation of the Father

Thai law provides mechanisms through which an unmarried father may become legally recognised in a way that affects parental rights. Depending upon the circumstances, legitimation may arise through:

• subsequent marriage of the parents;
• registration according to Thai law; or
• a court judgment.

This can become crucial in disputes involving custody, parental power, passports, international travel, schooling, medical treatment and relocation. For detailed guidance, see the Child Legitimation guide.

Child Support

Parents remain responsible for supporting their children. Child maintenance should be considered separately from disputes between the adults. Important factors can include:

• the child's needs;
• education;
• healthcare;
• living expenses;
• the resources of each parent; and
• the actual care arrangements.

Do not use child support as leverage over contact. A dispute over contact does not automatically remove the obligation to support a child. For detailed guidance, see the Child Support guide.

Agreeing Child Support Privately

Parents can reach agreements concerning financial support. The arrangement should be clear and realistic. Consider:

• monthly support;
• school fees;
• medical expenses;
• insurance;
• extracurricular activities;
• major one-off expenses; and
• how future changes will be handled.

Where conflict is likely, vague verbal arrangements are risky.

Contact With the Other Parent

A child living primarily with one parent does not automatically mean the other parent's relationship with the child should end. Contact arrangements can be important for the child's welfare. But contact may need restriction or supervision where there are serious concerns involving violence, abuse, threats, substance misuse, abduction risk or other danger. Safety must be considered separately from ordinary parental conflict.

Domestic Violence and Evidence

Domestic Violence and Child Custody

Domestic violence can be highly relevant to decisions involving children. Violence against a spouse or partner may also affect the child's welfare even where the child was not the direct target. Where there are allegations of physical violence, coercive control, threats, psychological harm, stalking, sexual violence or intimidation, preserve evidence and seek appropriate protection.

For detailed guidance on protection orders, reporting and emergency contacts, see the Domestic Violence in Thailand guide.

Evidence in Custody Disputes

Useful evidence can include:

• school records;
• medical records;
• photographs;
• messages and emails;
• witness evidence;
• police reports;
• evidence of daily care;
• housing information;
• financial support records;
• travel records;
• evidence of threats or violence; and
• previous court or administrative documents.

Avoid manufacturing or manipulating evidence. Courts will consider credibility.

Passports, Travel and International Relocation

Passports and Children

International Travel vs Permanent Relocation

International travel and permanent relocation are not the same thing. A short holiday may raise different issues from permanently moving the child to another country. Before taking a child abroad where the other parent objects, establish:

• who holds parental power;
• whether consent is required;
• whether a court order exists;
• whether there are travel restrictions;
• the child's nationality;
• the destination country's law; and
• the risk of international proceedings.

Do not assume that being the parent with whom the child lives gives unlimited relocation rights.

International Child Removal

Taking or retaining a child across borders without proper legal authority can create serious consequences, including urgent Thai court proceedings, foreign court proceedings, immigration complications, passport disputes, enforcement applications and international child-abduction issues.

International Child Abduction — Proceed With Caution

International child cases can be highly technical. The legal route depends upon the countries involved, the child's habitual residence, existing parental rights, applicable treaties, court orders and the precise circumstances of removal or retention. Do not rely on informal internet advice in international child-abduction disputes. These cases can become urgent very quickly.

Relocation Within Thailand

Even moving a child from one part of Thailand to another can create practical conflict where it significantly affects schooling, contact, medical care, established routines or access to the other parent. Where parental power is shared or disputed, major relocation decisions should be handled carefully.

Children With Two Passports

A child with Thai and foreign nationality may hold more than one passport. That does not automatically mean either parent can freely relocate the child internationally. The underlying parental rights still matter. Passports are travel documents — they do not replace custody or parental-power rules.

Child's Nationality

Children of Thai-foreign relationships may have more than one nationality. Nationality can affect passports, travel, residence rights, consular assistance and future relocation. Do not assume that holding a foreign passport removes the relevance of Thai parental-power rules while the child is in Thailand. For further information on children and family rights, see the Children and Family Rights guide.

Additional Topics

Schools and Parental Disputes

Schools may become caught between separated parents. Parents should provide schools with accurate information concerning who holds parental power, who may collect the child, any court orders, emergency contacts, travel restrictions and any genuine safety concerns. Do not use the school as a battleground.

Property Belonging to a Child

Parents may have responsibilities concerning property legally belonging to a child. Do not assume a parent can freely sell, transfer or use the child's property as though it were their own. Certain transactions involving a child's property may require legal authority or court involvement.

Grandparents and Extended Family

Grandparents and extended family can play an important practical role in a child's life. However, family involvement should not be confused with automatic parental power. Where a child lives with grandparents after separation, the legal authority to make major decisions should still be clarified.

New Partners After Divorce

A parent's new relationship does not automatically remove their parental rights. A new partner does not automatically acquire parental power over the child. Where a step-parent wishes to obtain formal legal status, separate legal processes may be relevant.

Same-Sex Divorce and Children

Since marriage equality took effect in Thailand on 23 January 2025, same-sex spouses are part of the marriage and divorce framework. The same general divorce principles therefore apply to same-sex marriages.

However, issues concerning legal parentage, adoption, assisted reproduction and parental power may require separate analysis depending upon how the child became part of the family. Do not assume marriage automatically resolves all parentage questions. For detailed guidance see the Same-Sex Marriage & LGBTQ+ Rights guide.

Foreign Court Orders

A custody or divorce order issued overseas may be relevant in Thailand, but foreign orders are not always automatically enforceable in the same way as Thai court orders. The effect of a foreign judgment depends upon the country, the type of order, Thai procedural law, the issue involved and whether fresh Thai proceedings are required. Do not assume that simply showing a foreign order immediately compels every Thai authority to act.

Likewise, a Thai custody or divorce order may need recognition or registration in another country before it can be enforced there. International families should consider enforcement before reaching agreements that depend upon cooperation across borders.

Mediation

Where appropriate and safe, mediation can help parents resolve practical disputes without prolonged litigation. Possible issues include child residence, contact, school holidays, travel, child support, property, communication and handover arrangements.

Mediation is not suitable in every case, particularly where there is serious violence, coercion or intimidation.

Practical Guidance

Do Not Sign Under Pressure

Divorce agreements can affect property, children, maintenance, debt, parental power, travel and future rights. Do not sign documents you do not understand.

A spouse may be pressured to transfer land, transfer shares, empty accounts, sign away claims, accept debt, waive maintenance or sign child arrangements in order to obtain an uncontested divorce. Understand the effect before completing the transfer.

Protecting Yourself Before Divorce

If separation appears likely:

• copy important financial records;
• identify all major assets;
• identify all debts;
• preserve company records;
• preserve title deeds and ownership information;
• keep copies of passports and civil documents;
• preserve evidence relating to children;
• record major financial contributions;
• secure your personal documents; and
• obtain advice before signing settlement documents.

Do not unlawfully remove or hide assets.

Protecting Children During Separation

Parents should avoid involving children in adult conflict wherever possible. Do not use children to deliver messages, pressure a child to choose sides, make false allegations to gain leverage, threaten to remove contact solely over money, conceal important medical information, or deliberately undermine the child's relationship with the other parent without a genuine safety reason.

Where abuse or danger exists, appropriate protective steps may be necessary. Where a child is at immediate risk, contact the appropriate police and child-protection authorities.
