\n
The main objective of the confirmation letter is to affirm to the Thai Land Department that the funds used for the property purchase are the personal property of the Thai spouse, known as\u00a0Sin Suan Tua<\/em>. This is a crucial step because Thai law restricts foreign land ownership. The letter serves as a legal declaration that the property will not become a jointly owned marital asset, or\u00a0Sin Som Ros<\/em>, which would grant the foreign spouse a claim to the land.<\/p>\n<\/div>\n<\/div>\n\n
Who needs to sign the confirmation letter and where?<\/strong><\/h3>\n\n
Both the Thai national and their foreign spouse must sign the confirmation letter. Ideally, this is done together in front of the competent official at the provincial or local Land Office on the day of the property registration.<\/p>\n<\/div>\n<\/div>\n
\n
What happens if the foreign spouse is not in Thailand during the property transfer?<\/strong><\/h3>\n\n
If the foreign spouse resides overseas and cannot be present, they must have their signature on the confirmation letter certified by a Royal Thai Embassy or Consulate in their country of residence, or by a notary public.The Thai spouse then brings the original certified letter to the Land Office to complete the registration.<\/p>\n<\/div>\n<\/div>\n
\n
Are there any specific requirements for the funds used for the purchase?<\/strong><\/h3>\n\n
Yes, the Thai spouse must be able to demonstrate that the money used for the purchase is their personal property. According to the Civil and Commercial Code,\u00a0Sin Suan Tua<\/em>\u00a0includes assets owned before the marriage, personal gifts, or inheritance received during the marriage. A gift between spouses is lawful, but three things qualify it. Under sections 1471(3) and 1474(2) a gift to your spouse becomes their personal property unless the written gift declares it to be sin somros, which is what Supreme Court Decision 186\/2565 applied to land transferred between spouses. Under section 1473 the recipient then manages that property alone. And under section 1469 an agreement about property made between spouses during the marriage may be avoided by either of them at any time during the marriage, or within one year of its end, so a gift arranged to satisfy the Land Office is not necessarily final. Document the gift before the purchase, not on the day of it.<\/p>\n<\/div>\n<\/div>\n\n
What are the risks for the foreign spouse in signing this confirmation letter?<\/strong><\/h3>\n\n
The practical risk is real, but it is not the one usually described. Because the register shows the land as the Thai spouse’s personal property, she can in practice sell, mortgage or transfer it without your consent, and the registrar will act on the register. What the declaration does not<\/strong> do is release your matrimonial rights. It records where the purchase money came from. It is an administrative declaration, not a contract, and nothing in it purports to vary the Civil and Commercial Code. Your real protection is a right of your own registered over the land, a usufruct, superficies, lease or mortgage, entered on the day of the transfer.It is important for the foreign spouse to understand this before signing. On divorce the declaration is not ignored. It is strong contemporaneous evidence of what both of you stated at the time, and a court weighs it against the money trail when deciding whether the land is sin suan tua or sin somros. If the land is held to be marital property, section 1533 divides it equally. If the declaration stands, the land is not divided at all and your claim is for your contribution rather than for the land.<\/p>\n<\/div>\n<\/div>\n\n
Can a Thai national who has renounced their Thai citizenship still own land in Thailand?<\/strong><\/h3>\n\n
No, an individual who has given up their Thai citizenship is generally not permitted to purchase land in Thailand, as this right is reserved for Thai nationals. If a Thai citizen who already owns land later renounces their citizenship, they may be required to sell the property within a specified period.<\/p>\n<\/div>\n<\/div>\n
\n
Is a power of attorney a viable option if one party cannot be present at the Land Office?<\/strong><\/h3>\n\n
Yes, a power of attorney can be used. However, the Thai Land Department only accepts its official standard forms, known as\u00a0Tor Dor 21<\/em>\u00a0(TD21) for land and houses. There are others for condos or Nor Sor Sam. General power of attorney forms are not accepted for property transactions.<\/p>\n<\/div>\n<\/div>\n\n
What happens if a couple does not provide the confirmation letter?<\/strong><\/h3>\n\n
Without the jointly signed confirmation letter, the Land Office will not proceed with the registration of ownership in the Thai spouse’s name. The request for registration would need to be escalated to the Land Department to seek approval from the Minister, a process that can be complex and is not guaranteed to be successful.<\/p>\n<\/div>\n<\/div>\n
\n
Can Thai children own land in Thailand?<\/h3>\n\n
Thai children having a foreign parent can also buy or accept land as a gift. But if it is done in order to avoid the law, as example for the purpose of Foreign ownership, the land department will not register the transaction. Also, most Land Departments will refuse to transfer land to a child under 7 years old, because they consider that the child is too young, can\u2019t understand, and can\u2019t sign his name, which impacts their rights in land by a Thai national. However, there is no minimum age in the law to own land in Thailand. We have seen in the last years (2010 and after), an opening from the Land Department and they often agree to transfer a property on a child’s name. Each case is different and if this is what you want, you should contact your local Land Department to verify the process and if they will agree.<\/p>\n<\/div>\n<\/div>\n
\n
Can a foreigner own land in Thailand through a Thai wife?<\/strong><\/h3>\n\n
No. Your wife owns the land, in her own name, and you sign a declaration confirming the money was hers. Section 86 of the Land Code bars an alien from holding land, and marriage creates no exception.<\/p>\n<\/div>\n<\/div>\n
\n
Can my Thai wife sell the land without my consent?<\/strong><\/h3>\n\n
At the counter, in practice, yes. Section 1476 requires both spouses to agree to a sale of marital property, but the register shows the land as her personal property and the registrar acts on the register. Your remedy comes afterwards, in court. A registered usufruct or lease in your name stops the sale from erasing your position.<\/p>\n<\/div>\n<\/div>\n
\n
What happens to the land if we divorce?<\/strong><\/h3>\n\n
The court decides whether the land is marital property. If it is, section 1533 divides marital property equally. If you instead prove that you supplied personal funds, you recover the contribution. Either way you cannot take registered title, because section 94 of the Land Code requires an alien to dispose of land within a period of 180 days to one year set by the Director-General.<\/p>\n<\/div>\n<\/div>\n
\n
What happens to the land if my Thai spouse dies?<\/strong><\/h3>\n\n
You inherit the right but cannot register it. Section 93 permission is not granted in practice, so section 94 disposal follows. Where there are Thai children, leaving the land to them and holding a registered lifetime right yourself avoids the problem.<\/p>\n<\/div>\n<\/div>\n
\n
Can I get my money back if the marriage ends?<\/strong><\/h3>\n\n
You can claim it, but do not assume you will succeed. Proof means transfer records, the gift or loan document, and the Foreign Exchange Transaction Form. Decision 1523\/2565 is the warning rather than the recipe: the foreign funder there lost outright, because the loan agreement he relied on was held to be a sham papering over an arrangement the law does not let him have. Paperwork built to disguise the real transaction is the thing most likely to fail you, precisely when you need it.<\/p>\n<\/div>\n<\/div>\n
\n
Is it illegal to give my Thai wife the money to buy land?<\/strong><\/h3>\n\n
Giving her the money is lawful. Making a false statement about it at the Land Office is not. A documented gift made before the purchase makes the declaration true. A same day transfer routed through her account to produce the paperwork is the pattern section 267 of the Penal Code and section 96 of the Land Code exist to catch.<\/p>\n<\/div>\n<\/div>\n
\n
What is a usufruct and does it survive if she sells the land?<\/strong><\/h3>\n\n
A usufruct under sections 1417 to 1428 gives you the right to possess and use the land for your lifetime or for a fixed term of up to 30 years. Registered on the title, it binds a later purchaser, which Supreme Court Decision 2783\/2516 confirmed. It ends when you die and passes to no heir.<\/p>\n<\/div>\n<\/div>\n
\n
Did the 2026 nominee crackdown change anything for married couples?<\/strong><\/h3>\n\n
It changed the counter, not the law. The May 2026 Department of Lands circulars direct registrars to investigate the source of funds on cash payments of THB 2 million or more and appraised values above THB 5 million, and to share data with the Department of Business Development, the Anti-Money Laundering Office and the Department of Special Investigation. Couples who documented the money properly pass. Couples who did not now get asked.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n
Where this leaves you<\/h2>\n
Two documents govern this purchase and they answer different questions. The title deed answers who is registered. The Civil and Commercial Code answers who owns. The declaration you sign belongs to the first question, and firms that tell you it settles the second are working from a proposition Thai courts rejected in 2022.<\/p>\n
What you control is the paperwork on the day. Document the source of the money honestly, register a real right in your own name at the same visit, and the arrangement holds up whether the challenge comes from a Land Office investigation, a divorce court, or a probate file.<\/p>\n
