Love, Money and Thai Law: The Buriram Case
Reading time approx. 6 minutes
Anyone living as an expat in Thailand knows the bar stories: “If you build a house in your Thai girlfriend's name, it's hers. If she throws you out, you leave with nothing but your flip-flops.”
For a long time that was often bitter reality. But a quiet generational shift is happening in Thailand's courts: younger judges look more carefully at who actually paid. A case before Buriram Provincial Court (June 2020) shows this clearly – and leads straight to the legal concept of Sin Somros, the community property of a registered marriage, explained in this article.
TL;DR
A 2020 Buriram court case split a house and car between a Danish expat and his former Thai partner based on a documented paper trail of payments, not on whose name was on the title. Sin Somros (community property in a registered marriage) splits 50/50 automatically on divorce. Unmarried partners get no automatic share – they must prove joint financial contribution, as confirmed by Supreme Court Decision 97/2569. Land can only be titled to a Thai national either way.
As of October 2026. Orientation, not legal advice – have your individual case checked by a lawyer in Thailand.
The Case: When the Dream Ends in Court
5.7 million baht, a house and a car
A Danish expat invested around 5.7 million baht: a Honda CR-V for 1.7 million baht, a house for 3 million baht on his mother-in-law's land, plus further payments. Everything was registered in his Thai partner's name. After the housewarming party, it was over: “This is my house, this is my car.”
He went to court. The judge treated the relationship as a de-facto partnership and made it clear: without a settlement, she would order the house demolished and the car sold, with the proceeds split. Result: the car went to the Dane, she kept the house. The paper trail – transfers matching the construction phases – was decisive.

The Three Relationship Stages
Not every relationship is treated the same way under Thai law. The Buriram case mainly changes the picture for one of the three stages below.
Status, legal reality and what the case changes
| Status | Legal Reality | What the Case Changes |
|---|---|---|
| Casual relationship | Payments count as gifts. No claim for return. | Nothing. |
| Unmarried cohabitation | No automatic community property. Co-ownership only with proven joint contribution (CCC §§ 1356–1366). | Courts examine the contribution more closely – the name on the title alone is no longer enough. |
| Registered marriage (Sin Somros) | Automatic community property during the marriage. | Safest option. |
What is Sin Somros (สินสมรส)?
Sin Somros is the community property of a registered marriage under the Civil and Commercial Code – comparable to the German Zugewinngemeinschaft, but automatic (unless a prenuptial agreement says otherwise).
Included (CCC § 1474)
- Everything either spouse acquires during the marriage (salary, business income, property, vehicles, etc.)
- Fruits from one spouse's separate property (e.g. rent from a pre-marriage property)
- Assets from a will or gift, if expressly designated as Sin Somros
Not included – Sin Suan Tua (separate property, § 1471)
Property owned before the marriage, personal items, tools of trade, and inheritances or gifts expressly given to one spouse only.
On divorce (§ 1533), Sin Somros is generally divided 50/50 – regardless of whose name is on the Chanote or the vehicle registration.
The key difference for unmarried couples
With Sin Somros, the half-share applies automatically. With unmarried couples, the joint economic contribution must first be proven (the paper trail). That is exactly why Supreme Court Decision 97/2569 matters: unmarried partners received comparable protection, but only because they could prove joint acquisition. A registered marriage needs no such proof.
Exception in both cases: land can only be registered on a Chanote title in the name of a Thai national. Sin Somros does not change that – the foreign spouse has no direct ownership share in the land itself, only a possible monetary compensation claim.

HIG Hacks: How to Protect Your Assets
1. Never cash
Every payment by bank transfer with a clear purpose – exactly this paper trail was decisive in the Buriram case.
2. Sign contracts while the relationship is good
Usufruct or a registered long-term lease on the house provides protection while there is still agreement – afterwards it's usually too late.
3. Hire serious lawyers
Lawyers who understand the difference between co-ownership and Sin Somros are not a luxury once larger sums are involved – they're essential.
Conclusion
Thailand's courts are becoming more modern. Those who document have better chances. A registered marriage remains the clearest protection. Orientation, not legal advice – have your individual case checked.
