คำตอบสั้นๆ: no law in Thailand requires you to pay sin sod, and no court will order you to. It is a custom, and a serious one. Thai law recognises it only to answer one question: who keeps the money if the marriage does not happen. Section 1437 of the Civil and Commercial Code defines sin sod (สินสอด) as property given to the betrothed person’s parents in return for that person agreeing to marry, and it says the paying side can reclaim it if the marriage does not take place because of an important cause on the other side. That is the whole of the law. Everything else, the amount, the gold, the negotiation, is culture and family.
The distinction that decides everything: sin sod goes to her parents; khongman (ของหมั้น), the engagement gift, goes to the bride herself and becomes hers. They are refunded under different rules. See the comparison.
Looking for the short definition? See our glossary entry for บาป โซด. This page is for the decisions: how much, whether you have to, and whether you can get it back.
Is Sin Sod Legally Required in Thailand?
No. There is no statute obliging a man to pay sin sod, no minimum, no maximum, and no register. A marriage registered at the district office is valid whether or not a single baht changed hands.
Thai law goes further than merely not requiring it. Under section 1438, an engagement is not a ground for asking a court to compel anyone to marry, and any agreement to pay a penalty for breaking an engagement is ว่างเปล่า. So a written promise that a groom will forfeit a sum if he backs out cannot be enforced, and neither can a promise by the bride’s family to hand her over.
It is also worth being clear about what a ceremony does and does not do. A traditional Thai wedding, however large, does not create a legal marriage. Only registration at the amphur does. The Supreme Court made the point squarely in Decision 4656/2567: where a couple simply lived together by agreement, the fact that there had been no formal proposal, no sin sod or khongman, no traditional ceremony and no registration meant no marital property regime arose at all. The reverse holds too. You can have the proposal, the sin sod, the gold and three hundred guests, and still not be married in law. See how to get legally married in Thailand.
None of that makes sin sod optional in any social sense. Refusing outright, in most families, ends the engagement. What it means is that you are negotiating a family matter, not complying with a legal one, and you should approach it that way.
Sin Sod and Khongman Are Not the Same Thing
This is the single most common error in English-language writing about Thai weddings, and it matters, because the two are given to different people and come back under different rules.
| Sin sod (สินสอด) | Khongman (ของหมั้น) | |
|---|---|---|
| What it is | Property given in return for the woman agreeing to marry | Property handed over as evidence that the man will marry her: the engagement gift |
| Who receives it | Her parents, adoptive parents, or guardian | The bride herself |
| Who owns it afterwards | Her parents | Hers, outright, from the moment of the engagement |
| What completes an engagement | Nothing. Sin sod is not what makes an engagement valid. | Delivery of the khongman is what makes the engagement complete under section 1437 |
| Refund | Reclaimable if the marriage does not happen for an important cause on the betrothed party’s side, or circumstances that side is responsible for | Returnable to the betrothing party if the betrothed party breaches the engagement (section 1439) |
In practice both are usually handed over on the same day, often on the same tray, which is exactly why families and foreigners alike treat them as one payment. If there is any chance of a dispute later, the difference between “this gold is for your daughter” and “this cash is for you” is the difference between two legal outcomes. Say which is which, in front of witnesses, on the day. The statutory basis is section 1437.
How Much Is Sin Sod?
There is no legal answer, so what follows is what we observe in practice and what families in Thailand generally expect. Treat it as a map, not a price list. The figure is set by the bride’s standing, her family’s expectations, and the region, and it is negotiated between the two families rather than announced.
| สถานการณ์ | Commonly discussed range (THB) | หมายเหตุ |
|---|---|---|
| Rural family, no university education, previously married or with children | Often nominal, sometimes waived entirely | Where a bride has been married before, families frequently reduce or drop the expectation |
| Middle-class family, university educated | Roughly 100,000 to 300,000 | The most commonly cited band |
| Higher-status family, professional, or educated abroad | 500,000 to 1,000,000 or more | Expectations rise steeply with the family’s standing |
| Gold, given alongside the cash | Typically 5 to 20 baht weight of 96.5% Thai gold | One baht weight is about 15.2 grams. Gold is often the visible part of the ceremony |
Two practical points that no statute covers but every family understands.
Display and keep are different questions. A large part of sin sod is about face: the sum shown on the tray in front of the guests. It is entirely normal for the amount displayed to exceed the amount the family actually retains. If a figure sounds impossible, the useful and entirely respectful question, asked through your fiancée or a Thai intermediary rather than directly, is whether it is for showing or for keeping.
It is frequently given back. In many families the sin sod, or a large part of it, is returned to the couple after the ceremony as the parents’ contribution towards a house, a car, or a business. This is common enough that a foreigner who assumes the money is gone is often wrong. It is also not something you can rely on or ask about in advance without causing offence.
A word on how this is discussed. Sin sod is not a purchase, and framing it as buying a bride is both wrong and, to a Thai family, insulting. It began as, and largely remains, a demonstration that the man can support a household and a recognition of what the bride’s parents have invested in raising her. The families who ask for the most are usually the ones for whom the ceremony carries the most social weight. Approaching it with that in mind produces better outcomes than approaching it as a haggle.
Who These Rules Apply To
The betrothal provisions are เป็นกลางทางเพศ, and have been since the Civil and Commercial Code Amendment Act (No. 24) B.E. 2567 came into force on 23 มกราคม 2568. The Code no longer speaks of a man and a woman. It uses phu man (ผู้หมั้น), the betrothing party, and phu rap man (ผู้รับหมั้น), the betrothed party. That amendment rewrote section 1437 itself, the sin sod provision, so two people of the same sex can become betrothed and every rule on this page applies to them in the same terms. See การสมรสระหว่างเพศเดียวกันในประเทศไทย.
The same amendment raised the minimum age. Under section 1435 a betrothal may be made only where both parties have completed their eighteenth year, and a betrothal in breach of that is void. The previous rule was seventeen, so anything you read that still says seventeen predates January 2025.
Sin sod itself remains a custom with a gendered history, and this page describes the custom the way families actually practise it. The legal rules are not gendered, and where this page states a rule it uses the Code’s own terms.
Can You Get Sin Sod Back?
Sometimes, and the statutory rule is narrow. Under the third paragraph of section 1437, the betrothing party may reclaim sin sod where there is no marriage, and the reason is an important cause arising on the betrothed party’s side, or circumstances for which that side is responsible, making it improper or impossible for the betrothing party to marry them.
Read that carefully, because three conditions all have to hold.
| สถานการณ์ | Can the paying side reclaim the sin sod? |
|---|---|
| The wedding never happens, and the receiving side is responsible | ใช่, this is the case section 1437 is written for |
| The wedding never happens, and the paying side changed their mind | เลขที่ The refund right depends on the cause being on the other side |
| They married, then divorced a year later | เลขที่ The marriage took place, so the condition is not met. Divorce does not reopen sin sod |
| They had the ceremony but never registered the marriage | Contested and fact-dependent. Whether “no marriage” means no registration or no ceremony has to be argued on the facts. Take advice before assuming either way |
| The property was never really given in return for her agreeing to marry | Not a sin sod claim at all, though there may be another route |
That last line is where the case law is most useful. In Decision 1901/2559, at the formal proposal the man placed a land sale and purchase contract on the ceremonial tray, naming the bride’s mother’s daughter as the buyer. The sale later fell through. The Supreme Court held the land was not property given in return for the woman agreeing to marry, and therefore was not sin sod within section 1437 paragraph three. A promise, a contract, or an asset that was never actually transferred as consideration for the marriage does not become sin sod because it was presented on the tray.
And a warning about self-help. In Decision 7868/2560 the groom’s mother picked up a gold necklace and bracelet from the counter of a gold shop and took them. The court held that whether or not the items were sin sod or khongman, the man’s side had already delivered them to the bride’s mother on the wedding day, so the groom’s mother no longer owned them. If she believed the bride’s family had broken an agreement, her remedy was a civil claim, not taking the property back. Recovering sin sod is a court matter. Taking it yourself can be a criminal one.
What If the Engagement Is Broken?
Breaking an engagement is not costless, even though nobody can be forced to marry. Under section 1439, where one side breaks the engagement the other may claim compensation, and where it is the betrothed party who breaks it, the khongman must also be returned.
Section 1440 then sets out what compensation can cover, and it is narrower than people expect:
- damage to the body or the reputation of either party;
- expenses incurred, or debts taken on, in good faith and reasonably, in preparing for the marriage;
- loss from having disposed of property, or having given up or changed a job or business, in the expectation that the marriage would happen.
Where the betrothed party is entitled to compensation, the court may treat the khongman they already hold as all or part of it. These claims are personal, and the rule sits in section 1447 paragraph two rather than in section 1440: a claim under this chapter cannot be transferred or inherited unless it has been acknowledged in writing or the injured person has already brought the action. There is one exception written into that sentence, and it is the practical one: a claim under section 1440(2), for expenses or debt incurred in good faith in preparation for the marriage, เป็น transferable and inheritable. That matters because 1440(2) is usually the largest head of the bill.
The Deadlines, Which Are Short
This is the part that decides most real cases, and almost nothing written in English mentions it. The betrothal claims do not run on the ordinary limitation periods.
| Claim | กำหนดเวลา | ส่วน |
|---|---|---|
| Compensation for breach of the betrothal agreement (section 1439) | Six months from the breach | §1447/1 |
| Compensation where the other side’s gross misconduct caused the renunciation (section 1444) | Six months from when it was known or ought to have been known, and never later than five years from the act | §1447/1 |
| Return of the khongman after a breach (section 1439) or a renunciation (section 1442) | Six months from the breach or the renunciation | §1447/2 |
| Return of the บาป โซด under section 1437 paragraph three | Not in the six-month list. Section 1437 applies the undue enrichment rules, so the period is หนึ่งปี from knowing of the right to restitution, and in any event ten years from when it accrued | §1437 with §§412 to 419 |
The asymmetry is worth saying plainly: the khongman claim can expire in six months while the sin sod claim is still alive. Families who wait to see whether the relationship recovers routinely lose the shorter one without knowing it existed.
If One of Them Dies Before the Wedding
Section 1441 deals with this separately and the result surprises people: where either betrothed dies before the marriage, there is no claim for compensation at all, and the receiving side does not have to return the khongman or the sin sod, whichever of the two died. It is not a breach, and the statute does not treat it as one.
What section 1440 does not cover is disappointment, wedding guests’ travel, or the value of the relationship. And remember section 1438: a clause in an engagement agreement fixing a penalty for withdrawal is void, so drafting one achieves nothing.
How Sin Sod Interacts With a Prenuptial Agreement
They solve different problems, and one does not substitute for the other.
Sin sod is a transfer made before the marriage, largely to the bride’s parents, and it is spent, kept or returned according to family arrangement. It never becomes marital property, because it is not the couple’s, and it is not on the table in a later divorce.
A prenuptial agreement governs what happens to the couple’s property. In Thailand it must be made before the marriage is registered, recorded in the marriage register or attached to it and referred to there, and signed by both parties and two witnesses. Get the timing or the registration wrong and it is void: it cannot be added afterwards. That is the single most common way foreign couples lose the protection they thought they had.
The two questions worth asking together are these. If the bride’s parents return the sin sod to the couple and it goes into a house, whose is the house? And if you brought assets into the marriage, are they clearly separate property? Both are prenup questions, not sin sod questions. See ข้อตกลงก่อนสมรสในประเทศไทย, and if you are already married, postnuptial agreements. What marriage changes about your property generally is covered in the consequences of marriage in Thailand.
Handling the Conversation Well
- Never negotiate directly with her parents. In most families the discussion runs through your fiancée, an uncle, or a respected intermediary. Going straight at it yourself reads as disrespect however politely you do it.
- Ask what is customary in her family and her province, rather than what is customary in Thailand. The variation between regions and families is much larger than any national figure.
- Separate the gold from the cash out loud. Gold given to the bride is hers. Say so at the time.
- Do not sign anything promising a penalty if the wedding is called off. It is void under section 1438 and it damages the relationship for nothing.
- Keep a record of what was given and to whom. Not a contract, just clarity: photographs of the day, and someone who can say what was handed over. Every sin sod dispute that reaches a court turns on evidence of who received what.
- Deal with the prenup before the registration, on its own timetable, and do not let it get tangled up in the sin sod conversation.
Common Questions
Do you have to pay sin sod in Thailand?
Not legally. No Thai law requires sin sod, sets an amount, or lets a court order anyone to pay it. Socially it is a different matter: in most families it is expected, and refusing outright usually ends the engagement. What the law does is decide who keeps it if the marriage does not happen.
Is sin sod the same as a dowry?
Not really, and the English word misleads. A dowry in the historical European sense travelled with the bride to the groom’s family. Sin sod moves the other way: from the man’s side to the bride’s parents, in return for her agreeing to marry. “Bride price” is closer, though it also carries connotations the custom does not deserve.
How much sin sod is normal?
There is no legal figure. In practice, a commonly discussed band for a middle-class, university-educated bride is roughly THB 100,000 to 300,000, with 500,000 to 1,000,000 or more where the family’s standing is higher or the bride was educated abroad, plus gold of typically 5 to 20 baht weight. Amounts are often nominal or waived where the bride has been married before. It is negotiated between families, not fixed.
Can I get my sin sod back if we do not marry?
You can claim it back under section 1437 paragraph three only where the marriage does not take place and the reason is an important cause arising on the other side, or circumstances for which that side is responsible. If you were the one who withdrew, the refund right does not arise.
Can I get sin sod back after a divorce?
No. The refund right in section 1437 depends on there being no marriage. Once you have married, sin sod is settled, and divorce does not reopen it. Divorce deals with the couple’s marital property, which is a separate question.
What is the difference between sin sod and khongman?
Sin sod goes to the bride’s parents, adoptive parents or guardian, in return for her agreeing to marry. Khongman goes to the betrothed person as evidence the other will marry them, and becomes theirs outright once the engagement is complete. Under section 1439, if the betrothed party breaks the engagement the khongman must be returned; sin sod is refundable only under the narrower test in section 1437.
Can we agree in writing that the sin sod is forfeited if the wedding is cancelled?
No. Section 1438 makes any agreement to pay a penalty for breaking an engagement void, and no court will compel a marriage. What you can do is be clear at the time about what was given and to whom, which is what actually decides these disputes.
Does paying sin sod make us married?
No. Only registration at the district office creates a legal marriage in Thailand. A full traditional ceremony with sin sod and hundreds of guests creates no marital rights on its own, as the Supreme Court confirmed in Decision 4656/2567 in the converse situation.
Can the bride’s family keep the gold as well as the cash?
It depends on who it was given to. Gold given to the bride is khongman and becomes hers. Gold given to her parents as part of the sin sod is theirs. Because it is usually all presented together, saying clearly on the day which is which is worth more than any document afterwards.
Should I sign a prenuptial agreement as well?
They are separate questions, and a prenup is the one with a deadline. A Thai prenuptial agreement must be made before the marriage is registered and recorded in or attached to the marriage register, signed by both parties and two witnesses. It cannot be added later. If you have assets to protect, or if the sin sod may come back to the couple and go into property, deal with the prenup on its own timetable.
If You Need Advice
Most sin sod questions are family questions and we are not the right people to answer them. Where we do help is the legal side around the wedding: a prenuptial agreement drafted and registered in time, the marriage registration itself for a foreign spouse, and the occasional dispute where an engagement has ended badly and real money is involved.
A prenuptial agreement is 8,900 บาท and takes about five working days. A consultation, if you want to talk something through first, is 2,000 บาทต่อชั่วโมง. See our กฎหมายครอบครัวไทย hub, or การจดทะเบียนสมรส.
