Getting married in Thailand: the wedding is not the marriage

Thai law is unusually blunt about this. A marriage exists only when a registrar has entered it in a register — which means the ceremony, however elaborate, is a party held near a piece of administration. Understanding that one sentence reorganises everything else: which day matters, which office, which documents, why your name is about to be spelled in Thai, and why the property agreement you were planning to sign next year cannot be signed next year.

One sentence, and what it decides

Section 1457 of the Civil and Commercial Code is nine words long in Thai and does more work than the rest of the chapter combined: a marriage under this Code can exist only when it has been registered.

Not blessed. Not celebrated. Not witnessed by four hundred people. Registered — meaning that a registrar has entered it in the marriage register.

Everything people find confusing about marrying in Thailand comes out of that. The ceremony can be as religious or as secular as you like, and can happen a week before or a year after the registration, because it is not part of the legal act. The hotel package that includes a “registration ceremony” with a man in uniform is either a real registrar who has come out from the district office — a real thing, with a fee we will come to — or theatre. And the anniversary that matters to the Land Department, to a bank, and to a court is the date on the register.

Section 1458 says how consent is given: a marriage may be made when two persons consent to be spouses, and that consent must be declared openly before the registrar, who shall record it. Ten minutes of paperwork, done aloud.

What changed on 22 January 2025

The Act Amending the Civil and Commercial Code (No. 24) B.E. 2567 is the marriage equality Act. It was published in the Royal Gazette in September 2024 and, by its own section 2, came into force when 120 days had passed from publication — 22 January 2025. It is a long Act because it does two things at once: it opens marriage to two people of any gender, and it rewrites the vocabulary of the whole of Book 5.

The administrative side followed with a day to spare, or rather a day late. The Ministry of Interior regulation on family registration (No. 4) B.E. 2568 was published in the Royal Gazette on 20 January 2025 and, by its clause 2, took effect on 23 January 2025 — the day after the Code changed. Its opening recital says plainly why it exists: the amending Act allows two people of any gender to become engaged or to marry and replaces the words man, woman, husband, wife and husband-and-wife with person, the two parties to an engagement and spouse, which affects the work of registering and recording family registers. Its clause 6 replaces the list of printed forms, so the marriage register and the certificate handed over today are different pieces of paper from the ones issued before that date.

What the registrar is actually checking

Clause 13 of the family registration regulation sets out the whole procedure at the counter: check the application and the identity evidence of both applicants; check that both have the qualifications the law requires, and where an applicant is a minor, check the evidence of consent; complete the entries in the marriage register (form คร.2) and the marriage certificate (form คร.3); have the applicants, anyone giving consent and the witnesses sign the register; sign it; and hand each spouse one copy of the certificate.

The qualifications being checked are these:

• Section 1448 — both parties eighteen complete years of age, unless the court has permitted an earlier marriage for good cause.
• Section 1449 — neither party of unsound mind, nor adjudged incompetent by a court.
• Section 1450 — not blood relatives in the direct ascending or descending line, and not brother and sister of full or half blood; and that relationship counts by blood whether or not it is legitimate.
• Section 1452 — neither party already has a spouse.
• Section 1453 — where a woman’s previous marriage ended by death or otherwise, not less than 310 days must have passed, unless a child has been born in the meantime, or she is marrying the same spouse again, or a doctor certifies that she is not pregnant, or the court has ordered that the marriage may take place. The 2024 Act kept this section.
• Sections 1454 to 1456 — where one party is a minor, the consent of those entitled to give it, which may be given by signing the register at the time, by a written instrument naming both parties, or, where necessary, orally before at least two witnesses. Consent, once given, cannot be withdrawn.

The ministerial regulation adds a power that is easy to overlook: where the application is not in the proper form, or is defectively written, or there is reasonable cause to suspect that the conditions of the Code are not met, the registrar may summon the applicants for examination before accepting the registration. That regulation dates from 1935 and still cites the Code’s section numbers as they stood then, so read it for the power rather than for the cross-references.

The documents, and why nobody can give you a definitive list

This is the question every forum thread is about, and the honest answer is in clause 8 of the family registration regulation.

Its first paragraph tells the registrar to check the applicant’s identity card — or, for people not required by law to hold one, another card issued by the authorities, or the alien certificate — together with a copy of the house registration. Its second paragraph then says what to do about everyone else:

That is a discretion, not a checklist. It explains the thing foreigners find maddening: the affirmation of freedom to marry — the letter from your embassy saying you are single and free to marry — is asked for at every district office in Bangkok and is named in no statute or regulation we could find. It is what registrars have settled on as the evidence that satisfies the second paragraph, because it is the only document a foreign government routinely issues that speaks to section 1452.

It also explains why two offices can want different things, why the list changes, and why arguing that the rules do not require a particular paper is a losing argument: the rule is that the registrar must be satisfied, and the registrar decides what satisfies them.

What the regulation is specific about is language. Clause 11 requires that where an applicant produces documents or evidence in a foreign language together with a certified Thai translation, the registrar enters the particulars in the family register in Thai. And clause 37, dealing with the recording of a family status established abroad, names who may certify such a translation: the Ministry of Foreign Affairs, a Thai embassy or consulate, the embassy or consulate of that country, or a body to which that country’s government has assigned the task. That is the chain the legalisation counter at Chaeng Watthana exists to complete.

The Thai spelling of your name

Clause 9 has a third paragraph that almost nobody is warned about, and it decides something permanent.

Where an applicant, a person giving consent or a witness wishes to sign in a foreign language, the registrar shall ask that person how the first name, middle name and family name sound in Thai, and shall write that in Thai alongside the signature.

So a Thai rendering of your name is produced, out loud, at a counter, in a hurry, on your wedding day — and that rendering is what appears on the register. Every subsequent Thai document that has to match your marriage record will be compared against it. There is more than one defensible way to write most foreign names in Thai script, and the moment to choose yours is before you arrive, not while a queue forms behind you.

The same clause covers the case where a person cannot sign at all: a thumbprint may be used, with the registrar noting whose it is, and if even that is impossible, the registrar records the obstacle in the signature space.

The prenuptial agreement, and its single window

Thai law gives couples a wide freedom to set their own property rules, and then gives them one opportunity to use it.

Section 1465: if the spouses have not made a special agreement about property before marriage, the relationship between them as to property is governed by the provisions of the chapter. The same section voids any clause in such an agreement that is contrary to public order or good morals, or that provides for the property to be governed by the law of another country.

Section 1466 then sets the form, and it is unforgiving. A prenuptial agreement is void unless:

• the terms agreed are entered in the marriage register together with the registration of the marriage; or
• the agreement is made in writing, signed by the parties and by at least two witnesses, attached to the marriage register, and a note is entered in the register at the same time as the registration recording that such an agreement is attached.

Section 1467 closes the door: after the marriage, the prenuptial agreement cannot be changed or revoked except by permission of the court, and when a final court order changing or revoking it exists, the court notifies the registrar so that it can be noted in the register. Section 1468 protects third parties who acted in good faith either way.

And clause 13(3) of the family registration regulation shows how mundane the mechanism is at the counter: when completing the marriage register and the certificate, where both applicants wish to have an agreement about property, or any other matter, recorded, the registrar shall write it in the record column.

One more piece worth knowing if you have complicated assets: section 1476/1 says that spouses may manage marital property differently from the joint-management rules in section 1476, in whole or in part, only if they have made a prenuptial agreement under sections 1465 and 1466. The management regime is inside the same window as everything else.

If you do nothing: the default regime

Most couples make no agreement, which is a decision rather than an omission. Sections 1470 to 1474 then apply.

Two consequences of that table are worth stating plainly.

The fruits of personal property are marital property. A condominium you owned for ten years before the marriage stays yours under section 1471(1). The rent it earns from the day of the marriage does not: section 1474(3) makes that marital property. The same goes for interest, dividends and the income from a business asset. It is the most common surprise in the chapter.

Doubt goes one way. Section 1474 ends by presuming marital property where the category is uncertain, so the burden of proof runs against whoever says a thing was theirs alone. Section 1472 helps a little: personal property exchanged for other property, sold, or destroyed and replaced with money or another asset, stays personal — but only if you can trace it.

Section 1473 leaves each spouse to manage their own personal property. Section 1475 lets either spouse ask to be named as co-owner in the documents for marital property of the kinds listed in section 456 — land and other immovables, and the movables that section covers — or for which there is a document of title. And section 1476 lists the dealings that need both spouses acting together or the other’s consent: selling, exchanging, selling with a right of redemption, letting on hire-purchase, mortgaging, releasing a mortgage or transferring a mortgage right over immovable property or mortgageable movables, among others. Where the law requires such an act to be in writing or registered, section 1479 requires the consent itself to be in writing.

Where, when and what it costs

Under the ministerial regulation issued in 1935, the district office (and, historically, the sub-district office) is the registry, and the Registration Division is the central registry. In Bangkok the equivalent is the district office of the fifty khet. Nothing in the rules ties you to the district you live in.

The fees are in clause 12 of that regulation, as amended in 1979, and they are a small museum of Thai administrative history:

• At the office: no fee is set, and none is charged.
• Registrar comes out at your request: 200 baht per case — and the applicant must provide the vehicle; if the applicant does not, the applicant must reimburse the registrar reasonably for the transport.
• At a marriage venue approved by the Minister of Interior: 20 baht.
• Away from the office in a remote locality, where the provincial governor has approved it for the general convenience of the public: 1 baht.
• Inspecting the register at the office that holds it or at the central registry: free. A certified copy: 10 baht. A search of the central registry through any registrar: 10 baht.

The regulation of 1998 adds a detail that turns the register number into a record of where you stood when you signed. Registrations away from the office use separate register and certificate stock, with a Thai letter placed in front of the number: ก for an ordinary off-site registration, then ข, ค, ง or จ where several are done at the same time; ท for a remote locality approved by the governor; and ร for the cases that need the Minister’s approval. In each case the registrar also writes into the record column where the registration took place.

And then there is clause 13(6), which is the only sentence in Thai registration law that anyone would call charming. Having handed each spouse a certificate, the registrar is directed to offer congratulations and to give such advice on the conduct of the duties between spouses as is appropriate. The blessing, in other words, is in the regulation. The ceremony is not.

Married abroad, or marrying abroad

Section 1459 deals with marrying outside Thailand where at least one party is Thai: it may be done in the form prescribed by Thai law or by the law of the country where it takes place, and where the couple want a Thai registration, a Thai diplomatic or consular officer is the registrar.

Coming the other way is where a limit appears that catches people out. Clause 36 of the family registration regulation allows an interested person to ask a registrar to record a family status established abroad in the form prescribed by the law of the country where it was made — and then adds: at the time of the request, one or both of the parties must be of Thai nationality.

Where the request is admissible, clause 37 requires the evidence of family status to be produced with a Thai translation certified by the Ministry of Foreign Affairs, a Thai embassy or consulate, that country’s embassy or consulate, or a body its government has assigned; the registrar then checks it, completes form คร.22, has the applicant and witnesses sign, and signs.

The emergency provision, and what it tells you

Section 1460 is rarely used and worth reading anyway, because it shows how seriously the Code takes the registration requirement. Where a special circumstance makes registration impossible — one or both parties in danger of death, or in a state of combat or war — the two may declare their intention to marry before a person of full age present at the place, who records the declaration as evidence. The marriage still has to be registered within ninety days of the day registration becomes possible, on production of that evidence; the registrar then notes the date, place and circumstances in the register, and the day of the declaration is treated as the day of registration.

Even at the outer edge of what the law will accommodate, the answer is still a register entry — just backdated.

What actually goes wrong

Treating the ceremony as the event. Couples who hold the ceremony and postpone the paperwork are not married in the meantime, with everything that follows for property acquired in between, for a spouse’s standing in a hospital or a police station, and for anything with a date on it.

Planning the property agreement for later. There is no later. Section 1467 means the next opportunity involves a judge.

Arriving with an untranslated document. Clause 11 requires the certified Thai translation before the particulars can be entered, and the certification chain in clause 37 takes days, not minutes.

Improvising the Thai spelling of a name. It takes thirty seconds at the counter and years to unpick.

Assuming the office you visited last year wants the same papers. Clause 8’s second paragraph is a discretion; telephone the specific district office, and ask what evidence they will accept from your nationality.

Reading a pre-2025 text. If the section you are looking at speaks of a man and a woman, of a husband and a wife, or of marriage at seventeen, you are reading the Code as it was before 22 January 2025.

Questions people actually ask

Is a wedding ceremony in Thailand legally binding?

No. Section 1457 of the Civil and Commercial Code says that a marriage under the Code can exist only when it has been registered. A temple ceremony, a beach ceremony, a hotel package that includes a costumed registrar, a water-pouring ceremony with both families present — none of these creates a marriage. They can happen on the same day as a registration, and often do, but the legal act is the entry in the marriage register at a district office, signed by a registrar.

What changed for marriage in Thailand in January 2025?

The Act Amending the Civil and Commercial Code (No. 24) B.E. 2567 came into force 120 days after its publication, on 22 January 2025. Section 1448 now requires both parties to be eighteen years of age rather than seventeen, with a court able to permit an earlier marriage for good cause. Section 1458 now says a marriage may be made when two persons consent to be spouses, replacing the wording about a man and a woman consenting to be husband and wife, and the same substitution of neutral terms runs through Book 5, including the title of the chapter on property between spouses. The registrars’ own rulebook followed a day later: the Ministry of Interior regulation on family registration (No. 4) B.E. 2568 was published on 20 January 2025 and took effect on 23 January 2025, replacing the printed forms for the marriage register and the marriage certificate.

Do I need a prenuptial agreement registered in Thailand?

If you want one, it has to be done in the same minutes as the marriage. Section 1466 provides that a prenuptial agreement is void unless it is entered in the marriage register together with the registration of the marriage, or unless it is made in writing signed by the parties and at least two witnesses, attached to the marriage register, with a note made in the register at the same time as the registration recording that it is attached. Section 1467 then provides that after marriage the agreement cannot be changed or revoked except by permission of the court. There is no later opportunity.

What becomes joint property when you marry in Thailand?

Section 1470 provides that property between spouses, other than that set aside as personal property, is marital property. Section 1471 defines personal property as property belonging to either party before the marriage, personal effects, clothing or ornaments suitable to station in life, tools necessary for carrying on a profession, property acquired during marriage by inheritance or by gift, and the engagement property. Section 1474 defines marital property as property acquired during marriage, property acquired during marriage by will or gift where the document says it is marital property, and the fruits of personal property. That last item surprises people: the rent from a condominium you owned before the marriage is marital property even though the condominium is not. Where it is doubtful which kind property is, the section presumes it is marital.

What documents does a foreigner need to marry in Thailand?

The statute does not list them. Clause 8 of the Ministry of Interior regulation on family registration says the registrar shall check the identity card, or another card issued by the authorities for persons not required to hold one, or the alien certificate, together with a copy of the house registration; and that where the applicant is a foreigner who cannot produce those, the registrar shall examine documents or evidence capable of proving who the applicant is and whether they hold the qualifications required by the Thai law on the matter. That is a discretion, not a checklist, which is why the affirmation of freedom to marry issued by an embassy is asked for everywhere and specified nowhere, and why two district offices can want different things. Clause 11 requires foreign-language documents to be produced with a certified Thai translation, and the register itself to be written in Thai.

How much does it cost to register a marriage in Thailand?

At the district office, nothing: the ministerial regulation issued under the Family Registration Act B.E. 2478 sets fees for other things and none for registering at the office. Clause 12 sets 200 baht where the registrar goes out to register a marriage at the applicant’s request, and requires the applicant to provide transport or to reimburse the registrar reasonably for it. There are two cheaper exceptions in the same clause: 20 baht at a marriage venue approved by the Minister of Interior, and 1 baht for registration away from the office in a remote locality where the provincial governor has approved it for the general convenience. Inspecting the register is free, a certified copy is 10 baht, and a search of the central register is 10 baht.

Can two foreigners register a marriage in Thailand?

Registering a marriage and recording one already made abroad are different acts with different rules. For a marriage registered in Thailand, the Code sets conditions about age, capacity, relationship and existing spouses, and says nothing about nationality; the practical question is evidence, and clause 8 of the family registration regulation leaves that to the registrar. Recording a foreign marriage is where nationality does appear: clause 36 lets an interested person ask the registrar to record a family status established abroad in the form prescribed by the law of the country where it was made, but at the time of the request one or both of the parties must be of Thai nationality.

What happens to my name when I register a marriage in Thailand?

It acquires a Thai spelling. Clause 9 of the family registration regulation provides that where an applicant, a person giving consent or a witness wishes to sign in a foreign language, the registrar shall ask that person how the first name, middle name and family name sound in Thai, and shall write that in Thai alongside the signature. Clause 11 requires the registrar to enter the particulars in the register in Thai from the documents produced. The Thai rendering chosen in those few minutes is the one that later documents will be compared against, so it is worth arriving with the spelling you want and being able to say it.
