Who Gets What in a Thai Divorce: Divorce Law – กฎหมายไทยเข้าใจง่าย
Thailand splits the marital estate (สินสมรส, Sin Somros) equally when a court decides a divorce. Personal property (สินส่วนตัว, Sin Suan Tua) stays with its owner if proven. Prenups can change management and help with classification, but they cannot override the Civil and Commercial Code’s division rules or waive spousal maintenance (alimony).
1. Key Definitions
| Thai Term | Meaning | Division Rule |
|---|---|---|
| Sin Somros (Marital Property) |
Assets and debts acquired during the marriage, e.g., salary, business income, joint savings, real estate, vehicles (section 1474). | Split 50 / 50 when the court divides (sections 1533–1535). |
| Sin Suan Tua (Personal Property) |
Owned before marriage; acquired during marriage by gift or inheritance; personal-use items; tools of trade; compensation for personal injury (section 1471). | Remains with the owner, if proven (section 1471). |
| Khongman (Engagement gifts) |
Gifts given in contemplation of marriage (e.g., ring, gold). Treated under specific Code provisions; generally personal, fact-dependent. | Typically personal; apply the relevant civil code provisions. |
2. Who Manages What During Marriage?
Under section 1473 of the Thai Civil and Commercial Code, each spouse manages their own sin suan tua (personal property). section 1476 governs sin somros (marital property): routine transactions can be handled by either spouse, but certain major acts, such as selling or mortgaging land, granting a lease over 3 years, or creating a pledge, require both spouses’ consent.
A prenuptial agreement can change how marital property is managed (for example, assigning signing authority over bank accounts or rental income). However, it cannot change the legal classification of what is personal vs. marital property, nor override the equal division rules in section 1533. The default rule in section 1474 still applies: property acquired during marriage is presumed marital unless it falls within a statutory exception (inheritance, gift, or replacement for personal property).
3. Who Gets What at Divorce?
A) If you agree (uncontested divorce)
B) If the court decides (contested divorce)
- Equal division of Sin Somros. The judge divides the marital estate 50/50 (section 1533). “Common debts” are also shared (section 1535).
- Reconstituting the pot. If a spouse hid, dissipated, or transferred assets without required consent, the court can restore those values for division (section 1534).
- Personal property stays personal. The spouse claiming “personal” bears the proof burden. If proof is weak, the section 1474 presumption (marital) prevails.
Under the Thai Civil and Commercial Code, the general rule is that marital property (Sin Somros) is divided equally between spouses upon divorce, unless proven to be personal property (Sin Suan Tua) under Sections 1471–1473. One key provision is Section 1474, which defines what is included in the marital estate (read more: Divorce in Thailand).
4. Gifts Between Spouses (Read This)
Valid but voidable: A gift made between spouses during marriage (even if registered) counts as an agreement between husband and wife. Under section 1469, either spouse can void such agreements during marriage or within 1 year after divorce (good-faith third parties protected). If voided, the court applies undue-enrichment rules (sections 406–419) to restore value (often a refund of what was given).
- If unchallenged: the gift may stand and be treated as the recipient’s personal asset.
- If challenged in time: the gift can be unwound and compensation ordered, don’t rely on spousal gifts as bullet-proof planning.
5. Key Case for Expats: Foreign-Funded Home in Thai Spouse’s Name
Supreme Court Decision 1523-2565 (2022). A foreign spouse paid for a house registered in the Thai spouse’s name during marriage. The local land office issued a “letter of confirmation” stating that the property was the Thai spouse’s personal property. The Supreme Court held that such an administrative document has no legal force to change property status under Section 1474 of the Civil and Commercial Code. Because the house was acquired during marriage, it was presumed sin somros (marital property) and included in the marital estate. However, the foreign spouse was entitled to reimbursement for the proven amount of personal funds invested.
Practical takeaway: A land office confirmation letter does not overrule the Civil Code. In a divorce, courts will apply the legal presumption that assets acquired during marriage are marital unless lawfully excluded. Keep detailed financial records to prove personal contributions and secure reimbursement.
6. Prenuptial Agreements: What They Can (and Can’t) Do
- Formalities: Written, signed by both spouses and two witnesses, and entered in the marriage register at the time of marriage (sections 1466–1467) or it’s void.
- No rewriting the Code: A prenup cannot override the equal division rule a court applies to Sin Somros, and cannot waive statutory maintenance (public-order limits).
- Where prenups help: They can tailor management (section 1476/1) and create strong classification evidence, e.g., “purchases paid from Spouse A’s personal funds are intended to remain Spouse A’s personal property.” Courts will consider this evidence where it doesn’t contradict sections 1471–1474.
7. Investment Growth, Foreign Assets, and Dual Prenuptial Agreements
Key point: Assets owned before marriage are personal property (section 1472), but any profits, dividends, interest, rents, and capital gains generated from those assets during marriage are treated as the “fruits” of property and therefore presumptively marital property (Sin Somros) under section 1474(3). In practice, unless there is clear documentation showing a lawful exclusion, investment growth during marriage is usually brought into the marital pool.
Supreme Court Adjudication No. 1296-2558 reaffirms that in case of doubt, property is presumed marital. This presumption would likely apply to investment gains unless clearly documented and lawfully excluded under the Code.
- Segregate accounts: Keep pre-marital investment accounts (e.g., brokerage, funds, crypto wallets) separate and avoid mixing returns into Thai joint or household accounts.
- Maintain a paper trail: Preserve statements, trade confirms, and bank transfers that show the pre-marital origin of principal and the timing of any gains.
- Use a Thai prenup for clarity: While it can’t override the civil code’s division rules, a prenup can set management rules and record the parties’ intent about classification (helpful as evidence if consistent with section 1471–1474).
- Consider a “dual prenup” abroad: A second prenuptial agreement under a foreign jurisdiction (e.g., Singapore, UK, Australia) may provide stronger protection for foreign-held assets if proceedings occur outside Thailand. It should be coordinated with the Thai prenup so they don’t conflict.
Note: A foreign prenup does not force a Thai court to ignore the Thai Civil and Commercial Code, but it can control outcomes in foreign courts and improve clarity for assets held outside Thailand.
8. Practical Checklist
- Keep documents: title deeds, bank transfers, gift/inheritance instruments, this proves personal property or supports reimbursement.
- Keep annual summaries of marital vs. personal assets
- Consent matters: get both signatures for big transactions to avoid section 1476/1534 issues later.
- Uncontested route = flexible: if you can agree, register your settlement; you’re not chained to 50/50.
- Expect 50/50 in court: unless you prove otherwise with solid evidence.
Legal references: civil and commercial code if Thailand sections 1471, 1474, 1476/1476-1, 1466–1469, 1533–1535; Supreme Court Decision 1523/2565 (2022).
9. Conclusion: Fair Distribution Depends on Documentation
Thai law aims for an equitable division of marital property, but the outcome depends heavily on how each asset is classified and proven. Clear evidence (such as title deeds, bank statements, and contracts) can make the difference between a 50/50 split and keeping an asset as personal property. A properly registered prenuptial agreement and consistent financial records can significantly strengthen your legal position. These tools help avoid disputes, clarify asset ownership, and protect both spouses’ interests.
Bottom line: Property disputes in a Thai divorce can be complex, especially when foreign assets or mixed funds are involved. Early legal advice, careful planning, and meticulous documentation are the most effective ways to ensure a fair and legally sound distribution.
In addition to property division, Thai divorce law may require one spouse to pay spousal maintenance if the other cannot support themselves. Child support is a mandatory obligation until the child reaches 20, covering essentials such as food, education, and healthcare. Courts set amounts based on the child’s needs and each parent’s financial capacity. Read more:
Frequently Asked Questions
Click a question below to see the answer.
Only marital property (Sin Somros) is split equally when the court divides the estate (civil code sections 1533–1535). Personal property (Sin Suan Tua)—owned before marriage or received as a gift/inheritance, stays with the owner if proven (section 1471). In an uncontested divorce, spouses can agree to a different split and register it.
Not necessarily. If a home was acquired during marriage, it’s presumed marital under section1474 even if registered in one name (following the land office procedure 'acquisition of land by a Thai national married to a foreigner'). The other spouse may claim a half share, or reimbursement for proven personal funds used (see Scj.1523-2565 trend).
Yes, generally. Fruits (profits, dividends, interest, rents, and gains) of personal assets during marriage are presumed marital under section 1474(3). Courts apply a presumption that, in doubt, property is marital, so keep strong records if you claim otherwise.
No. A Thai prenup can set management rules and help classify assets, but it cannot override the Code’s division rules or waive statutory maintenance. It must be in writing, signed with witnesses, and registered at marriage (section1466–1467).
Gifts between spouses can be treated as personal if unchallenged, but they are voidable under section 1469 (during marriage or within 1 year after divorce). If voided, courts use undue enrichment rules (sections 406–419) to restore value, often by reimbursement.
In a court divorce, the judge applies the Code: marital property divides 50/50 unless proven personal. In an uncontested divorce, spouses can agree to a different, lawful division and register, often faster and more flexible.
Keep documents: pre-marriage title deeds, bank statements showing sources of funds, gift/inheritance instruments, and clear paper trails for transfers. Documentation is critical to rebut the section 1474 presumption.
No. Paying from personal funds does not change the asset’s status by itself, but you can claim reimbursement for what you contributed if you can prove it, this is the approach reinforced in recent case law (e.g., Scj. 1523-2565 trend).
