Legal Mistakes Foreigners Make Buying Property in Thailand — 2026 Warning Guide

The most costly mistake foreigners make when buying property in Thailand is skipping independent legal due diligence — relying on the developer’s agent or salesperson to explain the legal structure. This single omission exposes buyers to title defects, invalid ownership structures, unenforceable contracts, and in extreme cases, total loss of their investment. The second most costly mistake is misunderstanding what they are actually buying: the legal difference between freehold, leasehold, and company-held land is frequently glossed over at the point of sale.

The 12 Most Expensive Legal Mistakes

#	Mistake	Typical Cost	Frequency
1	No independent lawyer	$50K–$500K+	Very common
2	Signing without legal review	$10K–$200K	Common
3	Not getting an FET form	Loss of title	Common
4	Using nominee shareholders	Criminal liability	Common
5	Unregistered lease	Loss on sale	Common
6	Not verifying foreign quota	Ownership dispute	Occasional
7	Overpaying booking fee	$3K–$15K	Common
8	Off-plan with no escrow	Developer bankruptcy	Occasional
9	No will or estate planning	Probate delays	Very common
10	Wrong currency for FET	Title rejection	Occasional
11	Ignoring building permits	Demolition risk	Rare but severe
12	Trusting agent’s legal advice	Variable	Very common

Mistake 1: Not Hiring an Independent Thai Lawyer

The single most common and expensive mistake. Buyers trust the developer’s sales team to explain the legal structure, believing there is no need for an independent lawyer if they “trust” the developer.

The problem: The developer’s lawyer works for the developer — not for you. Their job is to execute a transaction, not to protect your interests. They will not flag clauses in the SPA that favor the developer at your expense.

What you miss without independent counsel:

• Title search revealing encumbrances on the land
• Problematic clauses in the SPA (e.g., developer can delay completion indefinitely)
• Incorrect ownership structure for your circumstances
• Missing FET form requirements
• Weak renewal clauses in leasehold agreements

Cost of a good Thai property lawyer: THB 20,000–60,000 ($600–$1,800) for a full transaction. This is one of the best ROIs in any property purchase.

Our recommendation: Use MORE Group’s network of English-speaking Thai lawyers — 0% commission, transparent fees, full independence from the developer.

Mistake 2: Signing the SPA Under Pressure at a Presentation Event

Developers frequently invite prospective buyers to “exclusive presentations” with discounts available “only today.” These are high-pressure environments designed to get signatures before you consult a lawyer.

Real consequences: We have seen buyers sign SPAs at Phuket road shows that:

• Had completion dates so vague the developer couldn’t be held liable for 5-year delays
• Included “force majeure” clauses so broad that COVID, economic downturns, or even slow sales were grounds for indefinite delay
• Had no penalty clauses for developer default
• Required the buyer to waive legal recourse in case of dispute

Rule: Never sign a binding property agreement in Thailand without a minimum 3–7 day review by your independent lawyer. Reputable developers will accommodate this request.

Mistake 3: Transferring Funds in Thai Baht (Not Foreign Currency)

For freehold condo registration, the Land Department requires proof that funds were transferred into Thailand as foreign currency — evidenced by a Foreign Exchange Transaction (FET) form from the receiving Thai bank.

What happens if you transfer in Baht (from a Thai account)?

• No FET form is generated
• The Land Department cannot register freehold title in a foreign national’s name
• You are left with a contractual right but no registered title — vulnerable to dispute

Common scenario: A foreign buyer has accumulated Thai Baht from work, savings, or other sources in a Thai bank account. They attempt to use these funds to purchase a condo freehold. Without a fresh international wire — even if the net amount is the same — no FET form is issued and registration fails.

Solution: Always wire in foreign currency from an overseas account to a Thai bank for the purposes of a freehold condo purchase. Your Thai lawyer will specify the exact requirements.

Mistake 4: Using Nominee Shareholders for Land Ownership

The Thai company structure with nominee shareholders — Thai nationals who hold shares in name only, with the foreign buyer retaining economic control — is illegal under the Foreign Business Act and the Land Code Act.

Why people still try it: Agents and some lawyers (particularly those prioritizing commissions over ethics) present it as “common practice” and “not really enforced.” This is dangerously wrong.

The enforcement reality since 2022:

• The Department of Special Investigation (DSI) has active task forces targeting nominee arrangements
• Land Department officers routinely scrutinize company-held land for nominee patterns
• Several high-profile prosecutions have occurred, resulting in land forfeiture and deportation
• Thai shareholders in nominee arrangements also face criminal liability

Safe alternative: A genuine Thai business partner with independent capital, actual business activity, and proper governance — or simply accepting that villas can only be held as leasehold.

Mistake 5: Not Registering the Lease at the Land Department

Some buyers — particularly those purchasing from informal or smaller developers — sign a lease agreement but never register it at the Land Department. Sometimes the developer says registration will happen “later” or “is not necessary for your type of lease.”

Legal consequence: A lease for more than 3 years that is not registered at the Land Department is unenforceable against third parties. If the land is sold to a new owner, the new owner can legally evict you — your unregistered lease is not binding on them.

How to avoid: Demand to see the registration receipt from the Land Department before making final payments. Your lease annotation should appear on the Chanote title deed.

Mistake 6: Not Verifying Foreign Quota Before Signing

Buyers sometimes sign an SPA for a “freehold” unit in a building where the foreign quota is already full. The developer — whether through error or deliberate misrepresentation — has sold you a unit as freehold when it cannot be registered as such.

What happens: At Land Department registration, the transfer is rejected because the building’s 49% foreign quota is exhausted. You then either:

• Lose the unit (and possibly your deposit, depending on the SPA terms)
• Accept a leasehold instead of the freehold you paid for (and overpaid for)

Prevention: Before signing any agreement, instruct your lawyer to verify the building’s current foreign quota status at the Land Department in writing.

Mistake 7: Paying an Excessive Booking Fee Without Protection

Booking fees in Phuket range from $1,500 to $15,000+. Standard booking fees are $2,000–$5,000. Some developers — particularly for high-end projects — request larger fees.

The mistake: Paying a large booking fee that is declared “fully non-refundable” without reviewing the SPA terms first. If the SPA turns out to be unacceptable (poor completion timeline, unfavorable force majeure, etc.) and you need to withdraw, you lose the entire booking fee with no recourse.

Best practice: Negotiate a 7-day “SPA review period” — standard practice is that the booking fee is refundable if you decline to proceed after legal review of the SPA within an agreed timeframe.

Mistake 8: Buying Off-Plan Without Financial Protection

Off-plan condo purchases in Thailand carry developer completion risk. If the developer runs out of funds mid-construction, you may wait years for completion — or lose your investment entirely if the company goes insolvent.

Warning signs of higher-risk off-plan projects:

• Developer has no completed projects in Phuket
• Project is less than 20–30% sold at the time you’re considering buying
• No third-party escrow for buyer payments
• Developer is a single-project company with no parent corporate guarantee
• Unrealistically high “guaranteed rental yield” promises (12%+ annually)

Safer approach: Buy from established developers with multiple completed Phuket projects, verify that construction permits are in place, and consider purchasing units at a later stage of construction for reduced completion risk.

Mistake 9: Dying Without a Thai Will

Many foreign property owners in Thailand have no Thai will — they assume their home-country will covers all assets including Thai property. This is incorrect in most cases: Thai inheritance law applies to Thai-registered assets.

Without a Thai will:

• Thai intestate succession applies
• Probate takes 12–24 months minimum
• The process requires translation and apostille of many documents from your home country
• Legal costs are higher
• Your heirs may not receive the assets as you intended

Solution: A Thai will costs approximately THB 10,000–25,000 ($300–$750) from a Thai lawyer and is one of the most important documents a foreign property owner should have.

Mistake 10: Misunderstanding What “Freehold” Means in Phuket

Many buyers — particularly those who come from UK, Australian, or New Zealand property markets where “freehold vs leasehold” has specific meanings — misapply their home-country understanding.

Common confusion:

• “Freehold” in Thailand for condos means the unit title — it does not mean you own the land under the building
• The building structure itself is not freehold in the way a UK freehold house is
• A “freehold villa” advertised in Phuket is a contradiction — villas are always leasehold on the land component

The reality: In Phuket, “freehold” = your individual condo unit has a Chanote title in your name with no time limit. “Leasehold” = you have a contractual right to use the property for a defined period. Neither gives you land ownership.

Mistake 11: Ignoring Building Permit Status

A number of villas and older condos in Phuket were built without proper building permits, or with permits for different uses (e.g., a hotel license on what is sold as residential). This creates significant risks:

Potential consequences:

• Local authorities can order demolition of illegal structures
• Insurance is voided for structures without proper permits
• Sale to a Thai buyer is difficult (Thai buyers’ banks won’t lend on unpermitted structures)
• You may be liable for fines related to the illegal structure

Prevention: Your lawyer should verify the building permit (Bai Anuyat) and that the structure conforms to the approved plans. For older projects, an independent architect inspection is advisable.

Mistake 12: Trusting Agent Legal Advice

Real estate agents in Thailand are not licensed lawyers. Many are knowledgeable and ethical — but their job is to complete sales, and legal advice is outside their professional authority and qualification.

The most dangerous phrase in Thai property sales: “Don’t worry, we’ve done this hundreds of times — the lawyer is just a formality.”

Always consult an independent Thai lawyer for any property purchase over $50,000. The cost is trivial relative to the investment and the risks.

Frequently Asked Questions

What is the biggest legal risk when buying property in Thailand as a foreigner? +

The biggest legal risk is purchasing through an improperly structured ownership arrangement — particularly nominee Thai company structures for land ownership, which are illegal and can result in land forfeiture, criminal charges, and deportation. The second biggest risk is failing to register a leasehold, leaving you with no legal protection if the land changes ownership.

How do I find a trustworthy Thai property lawyer? +

Seek a lawyer who is: registered with the Thai Lawyers Council, has experience specifically in foreign property transactions in the area you're buying (e.g., Phuket), charges a fixed fee (not a percentage of the purchase price), and has no commercial relationship with the developer. More Group works with English-speaking Thai lawyers who are fully independent from developers.

Can I lose money on a Thai property purchase? +

Yes — you can lose money through: developer insolvency on off-plan projects, title defects discovered after purchase, invalid ownership structures (nominee arrangements), poor-quality construction requiring expensive remediation, and market downturns if you need to sell in a depressed period. Proper due diligence dramatically reduces (but does not eliminate) these risks.

Is it safe to buy a very cheap condo in Thailand? +

Very cheap condos (under $60,000 in 2026) in Phuket warrant extra scrutiny: they may be in poor condition, have unresolved title issues, be in buildings with significant debt or management problems, or be sold by developers with financial difficulties. The discount often reflects a real problem. Due diligence is even more important at the lower end of the market.

What should I check before signing any agreement in Thailand? +

Before signing: verify the seller is the registered owner (request the Chanote from your lawyer), confirm foreign quota availability (for condos), verify building permits exist and match the structure, have your lawyer review all contract terms including completion timeline and force majeure clauses, confirm the agreed ownership structure is legally sound for your nationality, and ensure the FET form process is understood.

Do I need a lawyer if I'm buying from a reputable international developer? +

Yes — even with reputable developers. The developer's legal team protects the developer's interests, not yours. Independent review often identifies completion timeline clauses, maintenance fee structures, handover conditions, and SPA terms that can be negotiated to better protect the buyer. The fee is typically $600–$1,800 and is always worthwhile.
