Dividing Property on Divorce in Thailand: What a Foreigner Needs to Know

Where the Division Begins

On divorce in Thailand, the fate of a property is determined not by whose name appears on the title document, but by the legal classification of the asset and by evidence of the origin of the funds used to acquire it. Thai family law divides all spousal property into two categories, and which category your house or condominium falls into determines whether it must be split equally.

• Sin Suan Tua (personal property) - property that belonged to a spouse before the marriage, or was received during the marriage as a gift or by inheritance, as well as personal effects and professional tools (Civil and Commercial Code, Section 1471). Not subject to division.
• Sin Somros (matrimonial property) - broadly, everything acquired during the marriage, including the 'fruits' of personal property such as rental income and interest (Section 1474). On judicial divorce it is divided equally (Sections 1533-1535).

The key point: a 'family home' does not automatically become matrimonial property. The law looks at legal classification and evidence, not at the entry in the land register.

Land and a Thai-Foreign Marriage

A foreigner cannot own land in Thailand. Since the Ministry of Interior Regulation of 23 March 1999 came into force, a Thai spouse married to a foreigner may purchase land only on the condition that it is registered as that spouse's personal property (Sin Suan Tua), not as jointly owned matrimonial property.

In practice, the procedure at the Land Office is as follows:

• the Thai spouse declares that the funds used for the purchase are personal funds (with reference to Section 1472);
• the foreign spouse signs a standard 'confirmation letter' (หนังสือยืนยัน) renouncing any claim to the land - but solely for registration purposes.

This renunciation allows the transaction to proceed. It does not mean, however, that the foreigner permanently loses all rights.

The Decision That Changes Everything: No. 1523/2565 (2022)

In Decision No. 1523/2565 (2022), the Supreme Court of Thailand confirmed a fundamental principle: even where a house is registered in the name of the Thai spouse and the Land Office has issued a letter stating that it is that spouse's personal property, such an administrative document cannot override Section 1474. That provision raises a presumption that any asset acquired during the marriage is matrimonial property (Sin Somros), unless a lawful ground for exclusion exists.

The practical takeaway: the 'confirmation letter' signed at the time of purchase is a formality required by the Land Office, not a waiver by the foreigner of their share in the asset. A foreign spouse who proves that they contributed personal funds is entitled to claim compensation for those contributions, even where the title is registered solely in the name of the Thai party.

The House and the Land Are Separate Assets

An important nuance of Thai law: land and the house built on it may be classified differently. The land may remain the personal property of the Thai spouse, while the house itself (its construction and value), built during the marriage using shared funds, is assessed separately and may be subject to division. For this reason, in any dispute the court evaluates not only the plot but also each party's contribution to the structure.

A Condominium - The Most Secure Option for a Foreigner

Where the property is a condominium unit, the position for a foreigner is fundamentally different. Under the Condominium Act, foreigners may own units up to a 49% quota of the total floor area of a building, directly and in their own name (freehold).

For such a unit to remain with the foreigner on divorce, it is critical that the correct procedure was followed from the outset:

• the purchase funds were remitted from abroad and evidenced by a Foreign Exchange Transaction (FET) form, formerly known as Tor Tor 3;
• the unit is registered in the foreigner's name personally, within the 49% quota.

Where the formalities have been properly observed, a condominium unit is generally treated as the personal asset of the spouse in whose name it is registered, and the issue of Thai land ownership does not arise.

Comparison of Options

Divorce by Mutual Consent and by Court Order

• By mutual consent. The spouses may agree on any lawful division, including compensation or transfer of a share, and record it in a written agreement.
• By court order. The judge applies the 50/50 rule to matrimonial property. If one spouse has concealed or dissipated shared assets, those assets may be 'restored' for the purposes of division (Section 1534).

Documentary evidence is decisive: bank transfer receipts, sale and purchase agreements, and proof of the origin of funds. It is precisely such evidence of a personal financial contribution that enables a foreigner to substantiate a compensation claim.

What to Check and What to Bear in Mind

• Classification of the asset. Determine in advance whether the property will constitute Sin Suan Tua or Sin Somros; the name in the register is not the same as the legal right.
• Keep evidence of the funds. Overseas transfers, the FET form (Tor Tor 3), bank slips, and contracts are essential - without them it is nearly impossible to prove an entitlement to compensation.
• A 'confirmation letter' is not a waiver of your share. Signing for the Land Office does not deprive you of the right to claim reimbursement of funds you invested.
• A condominium is more secure than land. When purchased within the 49% quota and documented with an FET form, the unit remains your personal asset.
• Distinguish land from the structure on it. A house built during the marriage may be subject to division even if the plot is the personal property of one spouse.
• Prenuptial agreement. An agreement drawn up before the marriage and duly registered allows the status of property to be fixed in advance.
• Leasehold and usufruct. Review the terms of the agreement and the entries in the register - these will determine the fate of the right on divorce.
• Local legal advice. Thai case law on mixed marriages is nuanced; the treatment of any specific asset is best verified with a Thai lawyer.
