Marriage and property rights in Thailand
Marriage changes how property, debt, and assets are treated under Thai law, especially in Thai-foreign unions where condominium ownership, land restrictions, and pre-existing wealth collide. Understanding sin somros versus sin suan tua before and after registration protects both partners.
Thai Visa Centre helps couples register marriage, coordinate prenuptial agreements, and plan marriage visa financial proof. This guide summarises property implications under the Civil and Commercial Code for June 2026. See our marriage in Thailand guide and prenuptial agreement guide for registration context.
Assets owned before marriage, personal gifts, inheritances kept separate.
Assets acquired during marriage divided equally on divorce absent prenup.
Marriage to Thai national does not grant foreign land ownership.
Separate from property law. Proves visa eligibility in applicant name.
Thai marital property system overview
Thailand follows a regime of marital assets unless a valid prenuptial agreement states otherwise. On divorce, marital property is generally divided equally unless a registered prenup or court order dictates otherwise. Personal property returns to the original owner. Disputes arise when assets are commingled.
| Category | Typical examples |
|---|---|
| Personal property (sin suan tua) | Assets owned before marriage, personal gifts, inheritances if not commingled. |
| Marital property (sin somros) | Assets acquired during marriage, income from personal property during marriage, jointly purchased property. |
Foreign ownership rules still apply when married
Marriage does not override Thailand land and property restrictions for foreigners. Buying property together requires title deeds, loan documents, and contribution records more than wedding rings.
| Asset type | Foreign spouse rule |
|---|---|
| Land | Foreigners cannot own land. Marriage to Thai national does not change this. |
| Condominium | Foreign quota 49% of units. Foreign freehold still requires qualifying foreign ownership. |
| Company-held property | Complex structures. Marriage does not simplify compliance. |
| Leasehold / usufruct | Common workaround. Contractual right, not ownership. |
Prenuptial agreements and property protection
A registered prenuptial agreement is the primary tool to ring-fence assets and define division. Critical: Thai prenups must be written, witnessed, and registered at the same amphoe as marriage before or at registration.
- Ring-fence pre-marital assets and foreign property abroad
- Define division of Thai condominium or business interests
- Address debt responsibility between spouses
- Clarify treatment of inheritances during marriage
Complex structures: Company-held property and cross-border estates require counsel registered with the Lawyers Council of Thailand. We specialise in registration, prenup coordination, and immigration.
Property bought before vs during marriage
| Timing | Default treatment | Risk if commingled |
|---|---|---|
| Before marriage | Personal property (sin suan tua) by default. | Using marital income to pay mortgage may create shared interest. |
| During marriage | Marital property (sin somros) by default. | Equal division on divorce absent prenup. |
| Inheritance during marriage | Personal if kept separate. | Depositing into joint account may convert character. |
Foreign bank accounts and pensions abroad may still be subject to Thai divorce jurisdiction if marriage is registered in Thailand. Home-country enforcement varies.
Divorce and property division
A registered prenup streamlines uncontested division. Without one, courts apply default equal division of sin somros. See our divorce in Thailand guide and Thai divorce law guide.
| Divorce type | Property outcome |
|---|---|
| Administrative (mutual consent) | Couple agree division in writing at amphoe. |
| Contested court divorce | Court divides marital property per law and evidence. |
Marriage visa financial proof
Non-Immigrant O marriage visa requires 400,000 THB in a Thai bank account in the applicant name or 40,000 THB per month verifiable income. These funds prove visa eligibility. They are not automatically marital property, but commingling can complicate both immigration audits and divorce evidence. Full guide: marriage visa.
Unmarried couples and property
Without registered marriage, cohabitation does not create marital property rights. Long-term partners should use explicit co-ownership on title deeds and written agreements. See our common-law marriage guide.
Frequently asked questions
General answers on marriage and property in Thailand. Complex property structures require Thai legal counsel. We specialise in registration, prenup coordination, and immigration.
Q:If my Thai spouse buys land, do I gain rights as a foreigner?
A:No. Land stays in the Thai spouse name. You have no ownership interest unless contractually granted through lease or usufruct.
Q:Does a prenup protect my condo in my name only?
A:A registered prenup can confirm pre-marital condo remains personal property. Register at marriage, not after.
Q:We paid 50/50 for a condo. Who owns it?
A:Title deed names control. If only one name appears, the legal owner holds the asset. Contribution evidence matters in disputes.
Q:Does divorce affect my marriage visa immediately?
A:The visa basis ends when marriage ends. Plan visa category change or departure. Do not overstay.
Q:Are marriage visa bank funds marital property?
A:Funds prove visa eligibility in the applicant name. They are not automatically marital property, but commingling with spouse accounts can complicate immigration audits and divorce evidence.
Q:What rights do unmarried couples have?
A:Cohabitation does not create marital property rights. Use explicit co-ownership on title deeds and written agreements.
Q:When must a prenup be registered?
A:Written, witnessed, and registered at the same amphoe as marriage before or at registration. Post-marital property agreements follow different rules.
Q:How is marital property divided on divorce?
A:Generally divided equally unless registered prenup or court order dictates otherwise. Personal property returns to original owner unless commingled.
