6 Legal Errors Foreign Buyers Make in Thailand Property

Foreign buyers lose money in Thailand not because the law is secret, but because they skip steps that a qualified local solicitor would treat as standard. The six mistakes below are drawn from recurring patterns visible in Thai property disputes as of 2026. Each one is preventable. Each one has a measurable cost.

This guide gives you the situation, the mistake, the warning signs that existed before the loss, the financial damage, and one prevention rule you can apply immediately.

Quick answer

• Nominee Thai company structures for residential land are illegal under the Land Code and the Foreign Business Act; penalties include forced divestment and criminal liability
• Unregistered leases above three years are unenforceable against a new landowner under the Civil and Commercial Code; verbal renewal promises have no legal standing
• Skipping a title deed search at the Land Office before signing means you may buy land encumbered by mortgages, servitudes, or a lower-class deed that carries no ownership rights
• Wrong transfer purpose on a bank wire invalidates the Foreign Exchange Transaction (FET) certificate - the document you need to repatriate funds and register a condominium in your name
• Signing handover without a written inspection report removes your legal basis for claiming defects under the developer's warranty period
• Verbal developer promises (pool size, completion date, furniture spec) that are absent from the sale-and-purchase agreement are not binding and are routinely not honoured

Options and scenarios

Is a Thai company a safe way to buy a villa or land?

No. This is the most expensive mistake a foreign buyer can make in Thailand.

Under the Land Code, foreign nationals cannot own land freehold. Some buyers form a Thai limited company, hold a minority share (typically 49%), and install Thai nominee shareholders who hold the majority on paper but have no real economic interest. The intent is to use the company as a vehicle to register land in its name.

This structure is specifically prohibited. The Land Code and the Foreign Business Act both treat nominee arrangements as illegal. Thai authorities have issued circulars - most recently reinforced in guidance published in 2024 - instructing Land Office officials to scrutinize company shareholding structures before accepting land transfers to Thai-majority companies with foreign directors.

Indicative cost of this mistake: A European buyer who purchased a villa plot in Koh Samui through a nominee company in 2021 and sold in 2025 found that the buyer's solicitor flagged the structure. The transaction collapsed. Legal fees to restructure the company before a second sale attempt: approximately THB 380,000 (market estimate). Lost rental income during the six-month delay: approximately THB 240,000.

Warning signs visible earlier: The agent who suggested the company structure could not name a specific legal opinion supporting it. The company had no business activity other than holding the land. Thai shareholder loans were documented but never actually transferred funds.

Prevention rule: If you want a house or villa, buy a condominium unit (where foreign freehold is permitted under the Condominium Act up to 49% of total unit area per project) or use a properly registered 30-year lease - registered at the Land Office on the title deed itself. Do not use a nominee company for any residential land purchase.

Does a lease contract protect you if the landowner sells the property?

Only if the lease is registered on the title deed at the Land Office.

Thailand's Civil and Commercial Code (Section 538) states that a lease of immovable property for more than three years must be made in writing and registered with the Land Office to be enforceable against third parties. An unregistered lease, regardless of its length or the quality of the contract document, does not bind a new owner who buys the land.

A common scenario: a retiree purchasing in Rawai, Phuket signs a 30-year lease with a landlord. The contract is drafted by a lawyer, signed by both parties, and witnessed. But the landlord says registration 'is not necessary' or 'will be done later.' The landlord then sells the land to a developer. The new owner is not bound by the unregistered lease. The retiree has no enforceable right to remain.

Renewal promises are even weaker. A clause stating 'the lease may be renewed for a further 30 years at the tenant's option' is not automatically enforceable under Thai law. Thai courts have generally treated renewal clauses as agreements to negotiate, not as binding options, when the renewal term was not registered separately.

Indicative cost: A Middle Eastern buyer paid THB 2.8 million as a lump-sum lease premium for a 30-year unregistered lease on a beachfront plot in Krabi in 2019. The landowner died in 2023. The heirs disputed the lease. Without registration on the title deed, the buyer had no registered right. Legal proceedings were still ongoing as of early 2026, with legal costs exceeding THB 320,000.

Warning signs visible earlier: The landlord offered a discount if registration was skipped. The lease document referred to renewal 'subject to mutual agreement.' No independent solicitor reviewed the deed class before signing.

Prevention rule: Insist on registration of the lease at the Land Office before, or simultaneously with, payment of any premium. Verify that the title deed presented is a chanote (Nor Sor 4 Jor - the highest class of title, confirming surveyed ownership) and that no existing encumbrances or mortgages appear on it.

What happens if you skip the title deed search?

You risk buying land that is mortgaged, subject to a right of way, in a protected forest zone, or held under a deed class that does not carry ownership rights.

Thailand uses several classes of land documents. The chanote (Nor Sor 4 Jor) is the only document that confirms full ownership with GPS-surveyed boundaries. Lower-class documents such as Nor Sor 3 Gor (a possession certificate) or Sor Por Gor 4-01 (a document used for agricultural reform land) cannot be transferred to foreign-owned companies and may not be mortgaged or leased in the same way.

A title search at the Land Office costs approximately THB 500-1,000 and takes one to two working days. It reveals: the current registered owner, any mortgages, any servitudes (rights of way, utility easements), any litigation annotations, and the document class.

Indicative cost: An American buyer signed a reservation agreement and paid a THB 500,000 deposit on a plot in Chiang Mai province described in the sales brochure as 'fully titled.' A post-payment title search revealed the land was Sor Por Gor 4-01 - agricultural reform land that cannot legally be transferred or used for residential construction by a private buyer. The developer refunded THB 300,000 after a dispute; THB 200,000 was treated as a non-refundable reservation fee under the contract the buyer had already signed.

Warning signs visible earlier: The developer could not produce a copy of the title deed before the reservation agreement. The agent described the land as 'government certified' without specifying the document class. The price per square metre was noticeably below comparable chanote plots in the same district.

Prevention rule: Obtain a physical or certified copy of the title deed before paying any deposit. Confirm it is a chanote. Conduct a Land Office search in the district where the land is located. Do this before signing any agreement, not after.

Why does a bank wire with the wrong description block your condominium registration?

Because the Foreign Exchange Transaction (FET) certificate - also called the Thor Tor 3 form - is mandatory for foreign condominium ownership registration, and the bank issues it only when the incoming transfer is coded correctly.

Under the Condominium Act, a foreign national who buys a condominium unit must prove that the purchase funds were transferred from abroad in foreign currency and converted to Thai baht in Thailand. The FET document is the proof. Without it, the Land Office will not register the unit in your name under the foreign ownership quota.

The problem arises when the buyer - or the buyer's bank - describes the transfer purpose as 'living expenses,' 'personal transfer,' 'loan repayment,' or any purpose other than 'purchase of condominium unit' or 'property purchase in Thailand.' Thai banks have the authority to issue the FET document, but they need the correct incoming wire description to do so. Some banks will also accept a supporting declaration, but practices vary by bank and branch.

Indicative cost: A Singaporean buyer transferred THB 4.2 million (equivalent) to a friend's Thai bank account to 'save on fees,' then paid the developer in cash from that account. No FET document existed. The Land Office refused to register the unit under the foreign quota. The buyer had to restructure: wire a fresh transfer from abroad, convert at current rates (which had moved), and absorb a currency loss of approximately THB 95,000 plus THB 45,000 in additional legal and banking fees.

Warning signs visible earlier: The agent suggested the transfer-to-a-friend method as 'simpler.' No independent legal advice was sought before the transfer. The buyer did not confirm the FET documentation process with the receiving Thai bank before sending funds.

Prevention rule: Wire funds directly from your overseas account to your own Thai bank account, or to the developer's account in a single transfer, described explicitly as 'purchase of condominium unit at, Thailand.' Confirm with the receiving Thai bank - before the transfer - that they will issue a FET document for the amount and purpose. Keep the original FET document; it is also the document that allows you to repatriate proceeds if you sell.

What does signing handover without an inspection report actually cost?

It removes your only documented basis for claiming defects under the statutory warranty period.

Developers in Thailand are subject to a defect liability period after handover - typically defined in the sale-and-purchase agreement, often set at one to two years for structural defects and shorter for finishes. Once you sign the handover acceptance form, the developer's position is that you accepted the unit as delivered. Without a written inspection report listing defects at the time of handover, you have no contemporaneous evidence that defects existed before you took possession.

Common defects found at handover in Thai new-build condominiums include: water infiltration through window frames, incomplete tiling, non-functioning air-conditioning units, electrical fittings that do not match specifications, and missing items from the furniture package if one was included.

Indicative cost: A buyer in a Pattaya high-rise signed the handover form under time pressure - the developer said the warranty would 'start from handover date regardless.' Within four months, a water leak from the unit above caused ceiling damage costing approximately THB 68,000 to repair. The developer denied liability, pointing to the signed handover acceptance as evidence that the unit was received in good condition. The buyer could not prove the defect predated handover. The repair cost was borne entirely by the buyer.

Warning signs visible earlier: The developer's representative was present at handover and visibly impatient. The handover form contained a pre-printed clause stating the buyer 'confirms the unit is in acceptable condition.' No independent snagging company was engaged before the handover appointment.

Prevention rule: Engage an independent inspection service before the handover appointment. Produce a written snag list. Sign the handover form only after the developer countersigns an acknowledgment of the outstanding defects list or after defects are repaired. Photograph and date-stamp every defect. Keep copies of all correspondence.

What happens when you rely on verbal promises from the developer?

Verbal promises are not enforceable under Thai contract law. Only what is written in the sale-and-purchase agreement (SPA) and its attachments is binding.

Marketing materials, brochures, scale models, and verbal statements by sales staff create commercial expectations but not legal obligations. Thai courts treat the SPA as the governing document. If the SPA says 'facilities as per the project plan' without specifying the plan, the developer has significant discretion over what is actually built.

Common promises that disappear between marketing and delivery include: pool dimensions, gym equipment specification, the number of car parking spaces per unit, furniture packages (items substituted with lower-spec alternatives), completion dates, and management fee structures.

Indicative cost: A buyer from Germany purchased an off-plan unit in Bangkok's Sukhumvit area in 2022, relying on a verbal promise from the sales team that the rooftop pool would be 25 metres long. The delivered pool was 12 metres. The SPA referenced 'rooftop leisure facilities' without dimensions. The buyer pursued a complaint through the Consumer Protection Board. The process took 14 months. The settlement was a THB 35,000 credit toward common area fees - a fraction of the premium the buyer believed was priced into the unit for the pool specification.

Warning signs visible earlier: The SPA referred to 'facilities as shown in marketing materials' without attaching the materials as a legally binding schedule. The sales team declined to have specific promises added to the contract. The buyer did not have the SPA reviewed by an independent solicitor before signing.

Prevention rule: Before signing the SPA, list every material promise made verbally or in brochures. Ask for each item to be added as a numbered schedule to the SPA, with measurements, specifications, and penalty clauses for non-delivery. If the developer refuses to put it in writing, treat that refusal as a signal about the reliability of the promise.

Risks and mistakes

Relying on the developer's in-house lawyer. Developers often offer a 'free legal service' to buyers. That lawyer acts for the developer, not for you. Their interest is to close the transaction, not to identify risks to your investment. Always engage your own independent solicitor.

Paying a deposit before any legal review. In Thailand, reservation deposits - typically THB 50,000 to 200,000 for condominiums, higher for villas - are routinely described as non-refundable. Once paid, your negotiating position over the SPA terms weakens significantly. Review the draft SPA before paying any deposit.

Assuming the project is financially sound because it is being built. Developer insolvency is a real risk in Thailand's off-plan market. As of 2026, several projects from the 2019-2022 sales cycle remain stalled or in dispute. There is no state-backed deposit protection scheme for off-plan buyers. Assess the developer's track record by inspecting completed projects, not by reading marketing materials.

Not checking the condominium juristic person's financial health. The juristic person is the legal entity that manages a condominium building on behalf of unit owners. If the sinking fund (a one-time capital reserve paid at purchase, used for major repairs) is depleted and common area fees are in arrears, you inherit a building management crisis when you buy. Request the juristic person's financial statements before committing.

Signing documents you do not understand. Thai-language contracts are legally binding. If you sign a Thai-language document without a certified translation and independent legal review, you are bound by its terms. Insist on a bilingual contract or a certified English translation reviewed by your solicitor.

FAQ

Can a foreign national own land in Thailand?

No. Foreign nationals cannot hold freehold land title in Thailand under the Land Code. The permitted routes are: freehold ownership of a condominium unit (up to 49% of total unit area per project under the Condominium Act), a registered long-term lease (up to 30 years, renewable by fresh agreement), or ownership through a Board of Investment (BOI) promotion in specific circumstances. Nominee company structures are illegal.

What is a chanote and why does it matter?

A chanote (Nor Sor 4 Jor) is the highest class of Thai land title document. It confirms GPS-surveyed boundaries and full ownership rights. Lower-class documents such as Nor Sor 3 Gor confirm possession but not ownership and carry restrictions on transfer and use. Always verify that the property you are buying is supported by a chanote before signing any agreement.

What is the FET document and when do I need it?

The Foreign Exchange Transaction (FET) document, also called the Thor Tor 3 form, is issued by a Thai bank when foreign currency is converted to Thai baht. For condominium purchases, you must present the FET document at the Land Office to register the unit under the foreign ownership quota and to repatriate funds when you sell. The transfer must be from abroad, in foreign currency, converted in Thailand, with the correct purpose stated.

Is a 30-year lease renewable in Thailand?

A 30-year lease is the maximum single-term lease permitted under Thai law. Renewal clauses in lease contracts are not automatically binding. A new 30-year lease must be negotiated and registered at the Land Office when the original term expires. The landowner at that time must agree to the new lease; there is no automatic right of renewal. Some contracts include pre-agreed renewal terms, but enforceability depends on registration and the wording used.

What is a sinking fund in Thai condominium purchases?

A sinking fund is a one-time capital reserve payment made by each buyer at the time of purchase, collected by the condominium juristic person. It is used to fund major future repairs such as roof replacement, elevator overhaul, or facade work. As of 2026, typical sinking fund rates in Thailand range from THB 400 to THB 700 per square metre, depending on the project (indicative figures). Check the fund's current balance and the juristic person's financial statements before buying a resale unit.

How do I check for encumbrances on a Thai title deed?

Visit the Land Office in the district where the property is located with a copy of the title deed. Request a title search (the fee is approximately THB 500 to THB 1,000). The search will show registered mortgages, servitudes, annotations of litigation, and any government notices affecting the land. Your solicitor can attend on your behalf with a power of attorney.

What documents should the developer provide before I sign the SPA?

The developer should provide: a copy of the title deed for the land on which the project is built, the project's construction permit (or evidence it has been applied for), the condominium registration certificate if the building is already registered, the draft SPA with all schedules, and the developer's company registration documents. If any of these are unavailable, request a written explanation and a timeline.

Are verbal promises by a developer's sales team enforceable?

No. Thai contract law treats the signed sale-and-purchase agreement as the governing document. Verbal statements, brochures, and scale models are not legally binding. Any promise that matters to you - pool size, completion date, furniture specification, parking allocation - must appear in writing in the SPA or its signed schedules.

What warranty period applies to new Thai condominium units?

Warranty periods are typically defined in the SPA. Thai consumer protection regulations provide some baseline protections, but the specific defect liability period and scope are largely contractual. As of 2026, most developer SPAs in Thailand specify one to two years for structural defects and shorter periods for finishes and fixtures. Your signed handover inspection report is the key document for enforcing any warranty claim.

Can I repatriate money when I sell my Thai condominium?

Yes, if you hold the original FET document for the purchase funds. The FET document proves the funds entered Thailand as a foreign currency transfer. When you sell, you can repatriate up to the amount shown on your FET document(s). Gains are subject to Thai withholding tax on the sale proceeds. If the FET document was never issued or has been lost, repatriation becomes administratively complex and may be limited.
