6 Legal Pitfalls Buying Thai Real Estate in 2026
By THAI.ESTATE Editorial Team16 min read
Foreign buyers lose money in Thailand not because the law is hidden, but because common mistakes are well-documented and still repeated. This guide breaks down six specific legal pitfalls, the warning signs that were visible before each mistake became costly, and the prevention rule you can apply before signing anything.
Thailand's property laws are strict about foreign ownership. Foreigners cannot own land freehold. They can own condominium units outright (up to 49% of a building's total floor area under the Condominium Act), hold long-term leases (up to 30 years registerable at the Land Department), or own structures separately from land. Every workaround that ignores these limits carries legal and financial risk.
Quick answer
- Thai nominee company structures for residential land are illegal under the Land Code and put your entire investment at risk of seizure
- Unregistered leases (not recorded at the Land Department) are unenforceable against a new landowner if the property is sold
- Skipping a title search before signing means you may buy land with encumbrances, disputes, or a low-grade deed that cannot be transferred
- Wrong FET wire reference (FET = Foreign Exchange Transaction form, the Bank of Thailand document proving foreign funds entered Thailand) can block your name from the condominium title deed permanently
- Signing handover without an inspection report leaves you with no legal record of defects, and developer liability expires in 5 years under the Civil and Commercial Code
- Verbal developer promises (sea views, facilities, rental guarantees) are unenforceable in Thai courts unless written into the sale and purchase agreement
Options and scenarios
Is a Thai company a safe way to buy a villa?
The short answer is no, not for residential use. Some buyers form a Thai limited company, place Thai nominees as majority shareholders (51% minimum), and use the company to hold land title. This structure is the most common legal pitfall buying Thai real estate.
The Land Code and the Foreign Business Act both treat nominee arrangements as illegal. The Department of Special Investigation (DSI) has prosecuted such cases. As of 2026, the Royal Thai Police and Land Department continue joint checks at popular foreign-buyer areas including Phuket, Koh Samui, and Pattaya.
What it looks like in practice. A buyer from Northern Europe purchases a villa in Rawai for THB 12 million using a Thai company with three Thai nominee shareholders holding 51%. A lawyer charges THB 60,000-120,000 to set up the company. The buyer pays company running costs of roughly THB 30,000-60,000 per year (audit, accounting, annual returns). Years later, a dispute with one nominee, a change in enforcement policy, or a sale attempt can expose the structure. The Land Department can refuse transfer, and the DSI can recommend dissolution of the company and forfeiture of the asset.
Visible warning signs before the mistake. The lawyer offering the structure cannot show you a Land Department ruling confirming it is legal for residential use. The nominees are strangers provided by the law firm. The company has no real business activity.
What it cost. In documented cases, buyers have lost the land asset entirely, paying again to convert to a long-term lease or to sell under distress at 20-35% below market price (per market estimates). Legal fees to unwind the structure range from THB 150,000 to over THB 500,000.
Prevention rule. If you want a villa, structure ownership as a 30-year registered lease with a contractual option to renew for two further 30-year terms (note: only the first 30 years is guaranteed enforceable at the Land Department). Separate ownership of the structure (house) from the land. Get the lease registered on the chanote (chanote = the highest-grade Thai land title, formally called Nor Sor 4 Jor) at the Land Department on the day of signing.
Can you rely on an unregistered lease or a renewal promise?
A lease of more than three years in Thailand must be registered at the Land Department to be enforceable against third parties under the Civil and Commercial Code. An unregistered lease exists only between the two original parties. If the landowner sells, the new owner is not bound by your lease.
What it looks like in practice. A retiree purchasing in Rawai signs a 30-year lease agreement with the developer. The developer promises registration 'after the structure is built.' The developer sells the land to a third party before registration. The new landowner asks the retiree to leave or to sign a new lease at double the rent. The original lease agreement is unenforceable against the new owner.
Visible warning signs. The sale and purchase agreement does not specify a registration date at the Land Department. The lease is signed at the developer's office, not at the Land Office. No government registration fee (currently 1.1% of the total lease value) is paid on signing day.
What it cost. Loss of the full lease term - commonly 20-28 remaining years. Replacement rent in the same area at 2026 market rates can exceed the original lease value by 40-80% (indicative figures). Legal costs to challenge the new owner range from THB 200,000 upward with no guarantee of success.
Prevention rule. Register the lease at the Land Department on the same day you pay. Bring your lawyer to the Land Office, not just to the developer's office. Confirm the title deed (chanote) is in the lessor's name, free of mortgage, before you transfer any funds.
What happens if you skip the title search?
Thailand has several classes of land document. Only the chanote (Nor Sor 4 Jor) gives full freehold rights and is freely transferable. Lower-grade documents such as Nor Sor 3 Gor (a confirmed certificate of use) or Sor Kor 1 (a notification of possession) carry restrictions or disputes that a buyer cannot see without checking at the Land Department.
What it looks like in practice. A buyer in Chiang Mai pays THB 4.5 million for a plot described by the agent as 'full title.' The document is a Nor Sor 3 Gor, not a chanote. The plot has a mortgage registered against it that the seller did not disclose. The buyer discovers the encumbrance only when applying for building permits six months later.
Visible warning signs. The agent or seller does not offer to take you to the Land Department before signing. The title document is not shown in original form. The sale price is below comparable chanote plots in the same area.
What it cost. In this scenario, resolving the undisclosed mortgage required THB 380,000 paid to the creditor plus THB 95,000 in legal fees. The plot could not be built on for 14 months. Upgrading Nor Sor 3 Gor to chanote status requires a Land Department survey process that typically takes 6-18 months and is not guaranteed to succeed.
Prevention rule. Always visit the Land Department with your lawyer before signing any transfer documents. Request a title search (costs roughly THB 500-2,000 and takes one to two working days). Confirm the deed class, check for any mortgage or servitude (a right registered for a neighbor's benefit, such as a right of way), and verify the seller's identity matches the title.
Why does the FET document matter for a condominium purchase?
FET stands for Foreign Exchange Transaction. Under the Condominium Act, a foreigner can register ownership of a condominium unit only if the purchase funds were transferred from abroad in foreign currency and converted to Thai baht in Thailand. The receiving Thai bank issues a Foreign Exchange Transaction Certificate (also called a Thor Tor 3 or FET certificate) as proof.
If the transfer reference is wrong - for example, stating 'loan' instead of 'purchase of condominium,' or sending baht from a Thai account - the bank may not issue a valid FET certificate, and the Land Department will not register the title in your name.
What it looks like in practice. A buyer from the Middle East transfers USD 180,000 to a Thai bank account in their own name held in Thailand, then pays the developer from that account. The funds originated in Thailand rather than arriving from abroad in foreign currency. The bank refuses to issue an FET certificate. The Land Department refuses title registration. The buyer owns a unit they cannot legally title.
Visible warning signs. No lawyer reviews the transfer mechanism before the wire is sent. The developer accepts payment without confirming FET compliance. The buyer's Thai bank account holds funds already converted from a previous transfer.
What it cost. Unregistered units sell at a discount of 15-30% compared to titled units (per market estimates). Some buyers have had to restructure the transaction by returning funds abroad and re-wiring correctly, paying conversion fees of 0.5-1.5% twice, plus legal and administrative costs of THB 50,000-150,000.
Prevention rule. Wire funds directly from your overseas bank account to the developer's account or to a Thai bank account opened for this purpose, in foreign currency (USD, EUR, GBP, etc.), with the transfer reference stating 'purchase of condominium at.' Confirm with your receiving bank in writing that they will issue an FET certificate before the wire leaves your home country.
What does signing handover without an inspection report actually risk?
Handover is the moment the developer hands you keys and you sign an acceptance document. If you sign without a written inspection report listing defects, you create a legal record that the unit or structure was accepted in satisfactory condition. Warranty claims become harder to enforce after that signature.
Under Thailand's Civil and Commercial Code, contractors carry a 5-year liability period for structural defects in permanent buildings. For finishing defects (tiles, fixtures, paintwork), the practical window to claim is much shorter once you have signed a clean acceptance.
What it looks like in practice. A buyer from East Asia accepts a Phuket condominium at a handover event organized by the developer. Staff present a two-page acceptance form. The buyer signs quickly. Three months later, water ingress from a poorly sealed window frame causes damage to furniture and flooring estimated at THB 85,000. The developer refers to the signed acceptance form and declines liability. The buyer's legal recourse requires proving the defect was pre-existing, which is difficult without a dated inspection record.
Visible warning signs. The developer schedules handover events for groups of buyers on the same day, creating time pressure. No independent inspection checklist is provided. The acceptance form does not have a 'defects noted' section.
What it cost. In the scenario above, repair costs were THB 85,000 and legal correspondence cost a further THB 40,000 with an uncertain outcome. Buyers who document defects at handover typically recover repair costs from developers within 60-120 days.
Prevention rule. Hire an independent property inspector (expect to pay THB 3,000-8,000 for a condominium unit, THB 8,000-20,000 for a villa) before attending handover. Bring the inspection report to the handover meeting. Do not sign a clean acceptance if defects are listed. Sign a conditional acceptance that names each defect and sets a remediation deadline in writing.
Are verbal developer promises enforceable in Thailand?
No. Thai contract law follows written agreements. Verbal promises made during sales presentations, including promised rental yields, guaranteed sea views, named facilities, and completion dates, carry no legal weight unless they appear in the signed sale and purchase agreement (SPA) or a written addendum.
What it looks like in practice. A buyer from Western Europe purchases an off-plan condominium in Pattaya at THB 3.2 million after a sales presentation showing a rooftop pool and a promised 7% annual rental guarantee for five years. Neither the pool nor the guarantee appears in the SPA. The pool is replaced with a smaller amenity. The rental guarantee scheme collapses when the developer's management company closes. The buyer has no written claim.
Visible warning signs. The SPA is shorter than 10 pages. Promised facilities are shown only in brochures, not attached as a schedule to the SPA. The rental guarantee is described in a separate promotional document that is not incorporated by reference into the SPA. The developer resists adding specific commitments to the contract.
What it cost. A rental guarantee at 7% on THB 3.2 million over five years is worth approximately THB 1.12 million. Recovering this through Thai civil litigation takes 2-5 years and costs THB 150,000-400,000 in legal fees with no guaranteed outcome, particularly if the developer entity has been dissolved.
Prevention rule. Before signing the SPA, list every promise made verbally or in marketing material. Ask the developer to include each item in the SPA or a signed addendum. If they refuse, treat the promise as non-existent. Have your lawyer review the SPA for omissions before you sign or pay any deposit.
Comparison table
| Mistake | Typical financial exposure | Time to discover | Legal remedy available |
|---|---|---|---|
| Nominee Thai company | Full asset value (THB 5M-30M+) | 1-10 years | Very limited - structure is illegal |
| Unregistered lease | Full remaining lease value | At resale or landlord change | Weak - only against original lessor |
| No title search | Encumbrance resolution cost (THB 100K-500K+) | 1-18 months post-purchase | Moderate - civil claim against seller |
| Wrong FET reference | 15-30% resale discount or re-transfer fees | At title registration | Moderate - restructure required |
| No inspection report | Repair costs (THB 20K-200K+) | Within first 12 months | Weak after clean acceptance signed |
| Verbal developer promises | Value of undelivered item (THB 100K-1M+) | At project completion | Very weak - no written evidence |
Risks and mistakes
Risk 1: Using one lawyer for both sides. Some developers recommend a lawyer. That lawyer may work primarily for the developer. You need your own independent legal counsel, instructed and paid by you, with no relationship to the seller.
Risk 2: Paying large deposits before due diligence. In Thailand, reservation fees of THB 50,000-200,000 are common and often non-refundable. Buyers sometimes pay under sales pressure before checking the title, the company's registration status, or the construction permit. Complete due diligence before any payment.
Risk 3: Ignoring the juristic person's financial health. A juristic person is the residents' management committee of a condominium building, established under the Condominium Act. It collects common area fees and the sinking fund (a one-time capital reserve paid at purchase, typically THB 400-600 per square meter). If a juristic person has accumulated deficits, you inherit financial risk. Ask for three years of audited accounts before buying a resale unit.
Risk 4: Assuming a power of attorney covers everything. Many buyers purchase remotely and grant a lawyer power of attorney. This is legal but creates a risk if the scope is not limited precisely. A broad power of attorney can allow the holder to transfer additional assets or sign documents beyond the intended transaction. Limit the power of attorney to specific transactions and dates.
Risk 5: Not verifying the developer's EIA and construction permit. Large condominium projects in Thailand require an Environmental Impact Assessment (EIA) approval. If a project is sold off-plan without valid EIA or construction permits, construction can be halted by authorities. Ask your lawyer to verify permit status before you pay any installment above the reservation fee.
FAQ
Can a foreigner own land in Thailand?
No. Foreigners cannot own land freehold in Thailand under the Land Code. The main legal alternatives are a registered long-term lease (30 years, registerable at the Land Department) or condominium unit ownership under the Condominium Act, limited to 49% of total floor area in any one building.
What is a chanote and why does it matter?
A chanote (Nor Sor 4 Jor) is Thailand's highest-grade land title document. It confirms precise GPS-surveyed boundaries and allows free transfer and mortgage. Lower-grade documents carry usage restrictions or boundary uncertainties. Always confirm the property you are buying has a chanote before proceeding.
What is an FET certificate and when do I need it?
An FET certificate (Foreign Exchange Transaction Certificate, sometimes called Thor Tor 3) is issued by a Thai bank when foreign currency is received from abroad and converted to Thai baht. You need it to register a condominium title in your name. Without a valid FET certificate, the Land Department will not transfer ownership to a foreign buyer.
How long is a lease in Thailand and is it renewable?
A lease registered at the Land Department is valid for up to 30 years. A renewal clause in the lease agreement is enforceable as a contractual right between the original parties, but a second or third 30-year term is not automatically guaranteed to be registerable on the land title. This remains a legal grey area as of 2026. Structure any renewal option with clear written terms and independent legal advice.
What is a sinking fund in a Thai condominium?
A sinking fund is a one-time capital reserve contribution paid by buyers at purchase, used for major future repairs to common areas (roof, lifts, pool). It is set by the condominium's juristic person and is typically THB 400-600 per square meter of unit size (indicative figures as of 2026). It is separate from monthly common area fees.
How do I check if a Thai developer is legitimate?
Verify the developer's company registration with the Department of Business Development (DBD) at dbd.go.th. Check whether the project has a valid Condominium Act registration (for condominiums) or EIA approval (for large projects). Ask your lawyer to search for any court cases filed against the developer entity.
Is a 30-year lease safer than a Thai company structure for a villa?
For a foreign buyer intending residential use, a registered 30-year lease is significantly safer than a nominee company structure, which is illegal under the Land Code. A lease does not give land ownership, but it is a recognized legal right, enforceable against the landowner for the registered term, and does not expose you to criminal or regulatory risk.
What should I check at handover of a new property?
Hire an independent inspector before the handover date. Check structural integrity, waterproofing, electrical fittings, plumbing, air-conditioning units, window seals, floor finish, and all fitted furniture against the specifications in your SPA. Record every defect in writing. Do not sign a clean acceptance until agreed defects are repaired or documented in a conditional acceptance form.
What happens if a developer goes bankrupt before project completion?
There is no statutory completion guarantee for off-plan buyers in Thailand as of 2026. Your recourse is as an unsecured creditor in bankruptcy proceedings, which typically recovers a small fraction of funds paid. To reduce this risk, limit installment payments to construction milestones verified independently, check the developer's financial track record, and review whether the project has any bank financing that signals institutional due diligence was completed.
Do I need a Thai lawyer or can I use a lawyer from my home country?
You need a lawyer licensed to practice in Thailand. Your home-country lawyer cannot review Thai land titles, conduct Land Department searches, or represent you in Thai legal proceedings. Hire an independent Thai lawyer with documented property transaction experience. Pay them directly, not through the developer.
