How to Check a Thai Developer's Track Record in 2026
By THAI.ESTATE Editorial Team15 min read

Vetting a Thai developer before you pay anything is the single most important step in a Thai property purchase. Most foreign buyers lose money not because the law failed them, but because they skipped verification. This guide gives you a practical, step-by-step playbook for 2026, written for someone buying from abroad without local contacts.
The core rule is simple: verify first, sign second. Thailand has no equivalent of a publicly searchable developer-registration database that covers every province, so verification requires combining online sources with a licensed Thai lawyer on the ground. What you can do remotely narrows the field; what your lawyer does closes it.
Quick answer
- Check completed projects first. A developer's finished, occupied buildings tell you more than any brochure. Look for at least two delivered projects with verifiable juristic-person registration (the legal management body of a completed condo building) before you commit.
- Confirm the land title class. Only a Chanote (full-ownership title document, formally NS-4 Jor) gives you the strongest legal footing. Nor Sor 3 Gor and lower-grade titles carry boundary and ownership risk. Your lawyer reads the actual document at the Land Department, not a scan.
- Demand proof of the building permit and EIA status. Selling from renders before a building permit is issued is legal in Thailand but is a serious risk flag. If the developer cannot show you the permit number, treat the project as pre-permit and price that risk accordingly.
- Understand how construction is financed. Projects financed by a Thai commercial bank (with a credit facility secured against the land) carry more structural accountability than projects funded purely from buyer instalments. Ask for the bank's name and the loan-security arrangement in writing.
- Map the payment schedule to construction milestones. Payments tied to verifiable physical progress (foundation poured, structure complete, fit-out complete, transfer) protect you. Front-loaded schedules where 30-50% is due before groundbreaking are a documented red flag.
- Run a litigation check. Thai court records are partially searchable via the Office of the Judiciary (judiciary.go.th). A Thai lawyer can run a deeper search. Multiple active cases involving the same juristic entity are a hard stop.
- Mark estimates as estimates. All yield figures and timelines in this guide are indicative for 2026 and should be verified for your specific project and province.
Options and scenarios
How do I check a Thai developer's completed-project track record?
The direct answer: you look for buildings that are finished, occupied, and legally registered as juristic persons.
Every completed Thai condominium must register a juristic person (the owners' committee entity under the Condominium Act) with the provincial land office. If a developer claims to have delivered five projects but none appear in provincial Land Department records as registered juristic persons, the claim is unverifiable. Your lawyer can confirm registration status in a single office visit or written inquiry.
For each completed project, you want to know:
- Advertised completion date versus actual transfer date. Delays of 6-12 months are common across the market; delays beyond 18 months indicate structural project-management problems.
- Whether buyers received Chanote title deeds at transfer. Some developers transfer units under lower-grade documents and blame 'processing time' for years after handover.
- Whether the juristic person is actively operating, collecting maintenance fees, and maintaining the building. A dormant or contested juristic person after handover signals unresolved post-delivery disputes.
You can start this research from abroad using Thai property forums (not advisory sites, but owner communities), Facebook groups for specific buildings, and Google Maps reviews of completed projects. These sources are unverified but give you leads to investigate. The verification happens on the ground.
How do I verify land title behind a Thai property project?
The direct answer: you commission a title search at the provincial Land Department through your Thai lawyer. There is no publicly searchable national online title database as of 2026.
Thai land titles rank by legal strength:
- Chanote (NS-4 Jor): GPS-surveyed, strongest title, preferred for any purchase.
- Nor Sor 3 Gor: surveyed but boundaries may be disputed; acceptable with caution.
- Nor Sor 3: rough measurements only; avoid for new development purchases.
- Sor Kor 1 / Por Bor Tor 5: possessory documents, not ownership; high risk.
A title search confirms the current registered owner, any mortgage or lien registered against the land (including the developer's own construction loan), any rights of way, and any court-ordered encumbrances. You pay for this search; expect indicative costs of 3,000-10,000 THB depending on the number of title documents reviewed. It is not optional.
If the land is mortgaged to a bank as security for the developer's construction loan, that is normal and can actually be reassuring - it means a bank has assessed the project. What matters is the legal mechanism that releases individual unit titles from that mortgage at the point of your transfer. Your sale-and-purchase contract must specify this release procedure explicitly.
How do I check EIA approval and building permit status?
The direct answer: EIA (Environmental Impact Assessment) approval is required for condominium projects above a certain scale (generally buildings over seven storeys or over 2,000 square metres of usable area in designated zones). Building permits are issued by the local authority (the municipality or district office).
You can request both document numbers from the developer in writing. A legitimate developer will provide them. You or your lawyer can then verify the numbers with the issuing authority.
The risk of buying before these approvals exist:
- A project can be legally marketed in Thailand before EIA approval or building permit issuance. This practice is common in off-plan sales.
- If EIA approval is later denied or conditioned, the project design may change materially, or construction may stop entirely.
- If a building permit is issued for a smaller building than was sold, units on upper floors may not receive title.
The cost of ignoring this: per market accounts of contested projects in Phuket and Pattaya, buyers in projects that stalled at EIA or permit stage have waited 4-8 years for resolution, with some still unresolved as of 2026. Recovery of instalments paid to failed developers typically requires civil litigation, which is slow and not guaranteed.
How do I assess construction financing?
The direct answer: ask the developer directly, in writing, how the project is financed. Verify the answer through your lawyer.
Three financing models exist in Thai development:
1. Bank project finance: A Thai commercial bank provides a construction credit facility secured against the land title. This is the most structured model. The bank has conducted its own due diligence on the developer and the project before lending. This does not eliminate risk, but it means an institutional lender has verified the fundamentals.
2. Mixed finance: Part bank loan, part pre-sale proceeds. Common and acceptable if the bank-finance component covers structural construction costs and pre-sale proceeds cover fit-out and marketing.
3. Buyer-instalment only (no bank finance): The project is built entirely from money paid by buyers at each stage. This model concentrates risk on buyers. If early sales are slower than projected, construction can stall. This is the highest-risk financing model for a foreign buyer.
You should ask: which bank holds the construction loan? What is the loan-to-project-cost ratio? Is the land free of mortgage, or mortgaged to the lending bank? The answers, verified by your lawyer, tell you whether your instalments are going into a structured development or directly propping up a cash-flow-dependent enterprise.
What can I verify remotely, and what requires a lawyer in Thailand?
This is a practical split that saves you time and money.
You can do remotely (before engaging a lawyer):
- Search the company name in the Department of Business Development database (DBD, dbd.go.th) - the site has an English-language company search. You see registration date, registered capital, and whether the company is active.
- Check registered capital. Indicatively, a serious developer building a multi-unit condominium should show registered capital commensurate with the project scale. A company registered with 1-2 million THB capital selling a 500-million-THB project is a mismatch worth questioning.
- Search Google News (site:bangkokpost.com or site:nationthailand.com) for the developer's company name. Press coverage of disputes, abandoned projects, or fraud allegations is searchable.
- Check the Office of the Judiciary website (judiciary.go.th) for case summaries linked to the company name. The search is in Thai; use a translator.
- Search owner communities and forums for completed project names. Real buyers in completed buildings leave traceable records.
Requires a Thai lawyer on the ground:
- Physical title search at the provincial Land Department.
- Verification of building permit and EIA approval with the issuing authority.
- Review of the sale-and-purchase contract (SPA) for delay penalties, force-majeure scope, milestone definitions, and title-transfer obligations.
- Litigation search through the Courts of Justice (more thorough than the public website).
- Verification of juristic person registration for completed projects.
- Review of the Foreign Exchange Transaction (FET) certificate requirement for foreign buyers transferring foreign currency into Thailand (the FET form, issued by a Thai bank, is required to repatriate funds later and to register condominium title in a foreigner's name).
Legal fees for full developer and project due diligence in 2026 run indicatively from 30,000 to 80,000 THB depending on complexity. This is not a cost to avoid. It is your primary protection.
What payment schedule terms are red flags?
The direct answer: any schedule that requires more than 20-30% of the purchase price before the building permit is confirmed and construction has demonstrably started.
Typical milestone-linked payment schedules for off-plan Thai condominiums look like this:
- Reservation deposit: 50,000-200,000 THB (refundable conditions vary - confirm in writing)
- Contract signing: 10-20% of purchase price
- Foundation complete: 10-15%
- Structure complete: 10-15%
- Fit-out / finishing complete: 10-15%
- Transfer of title: remaining balance (often 25-40%)
Red-flag schedules concentrate payments early. Paying 50% or more before a foundation is poured means you are financing the developer's land cost and pre-permit expenses. If the project fails before groundbreaking, your recovery depends entirely on litigation against a company that has already spent your money.
Contractual delay penalties are your other key protection. Thai law does not set a mandatory penalty rate, so it must be negotiated into the SPA. Market practice runs from 0.01% to 0.1% of the purchase price per day of delay beyond the contractual handover date. Confirm the penalty clause exists and is not capped at a nominal amount.

Risks and mistakes
Trusting the developer's own due-diligence documents
Developers routinely provide document packs at sales events. These may include title document images, EIA summaries, and permit references. None of these can replace independent verification at the issuing authority. A document image proves only that a document was photographed. Your lawyer verifies the original.
Skipping the lawyer to save money
This is the most common and most expensive mistake foreign buyers make. Legal due diligence on a Thai property purchase costs 30,000-80,000 THB indicatively. A failed off-plan project can mean losing 30-50% of a 3-10 million THB purchase price, with recovery taking years of litigation. The arithmetic is clear.
Confusing brand recognition with project quality
A developer may have a well-known brand and still deliver a specific project late, underfinanced, or with title problems. Each project must be vetted individually. The land behind Project C may have different title issues than the land behind the developer's earlier Project A.
Ignoring the FET certificate requirement
Foreign buyers of Thai condominiums must bring purchase funds into Thailand as foreign currency and obtain a Foreign Exchange Transaction (FET) certificate from the receiving Thai bank. This document is required to register the title in your name and to repatriate the proceeds if you sell later. Missing this step can make resale effectively impossible. Plan the funds transfer with your Thai bank before signing.
Accepting verbal milestone commitments
If the payment schedule tied to construction milestones is not in the signed contract, it does not exist legally. Verbal promises from sales agents carry no legal weight in Thai property disputes.
Assuming a bank-financed project is risk-free
Bank project finance reduces developer insolvency risk but does not eliminate it. If the bank calls in the loan, the land (which is the security) can be sold to recover the debt. Your contract must specify how individual unit titles are released from the bank's mortgage lien at transfer. This clause is non-negotiable.
FAQ
How do I check if a Thai developer is registered and legitimate?
Search the company name or registration number at the Department of Business Development website (dbd.go.th). The site has English-language company search. You can confirm the company is active, its registration date, and its registered capital. This takes under five minutes and costs nothing.
What is a Chanote title and why does it matter for my purchase?
A Chanote (formally NS-4 Jor) is Thailand's highest-grade land title. It is GPS-surveyed, registered at the Land Department, and gives the strongest legal proof of ownership and boundary. Buying a condo unit in a building that sits on Chanote land means your eventual title deed is legally sound. Lower-grade titles carry boundary disputes and ownership-challenge risks.
Can I buy a Thai condo from a developer who has no completed projects?
You can, but the risk is materially higher. With no completed project, you have no verifiable track record, no juristic-person registration to check, and no real buyer community to consult. If you proceed, the payment schedule must be heavily back-loaded, the contract must carry real delay penalties, and legal due diligence must be thorough. Treat the premium you are paying as entirely illiquid until the building is complete.
What delay penalty should I negotiate into my Thai condo contract?
Market practice for penalty clauses in Thai off-plan contracts runs from 0.01% to 0.1% of the purchase price per day of delay beyond the agreed handover date. Confirm the penalty is not capped at a total that makes it meaningless. A 0.01% daily penalty on a 5 million THB unit equals 500 THB per day, which covers holding costs on an annual basis. A higher rate is worth negotiating.
What happens to my money if a Thai developer goes insolvent before completion?
You become an unsecured creditor in a Thai insolvency proceeding. Recovery is not guaranteed and can take years. This is why front-loaded payment schedules are dangerous and why the developer's financing structure matters. Your practical protection is a payment schedule tied to verifiable milestones and a developer with a bank-financed project and a completed-project track record.
Is it safe to buy from a developer selling at international property exhibitions abroad?
The developer's presence at an international exhibition tells you nothing about the project's legal status. Many legitimate developers exhibit abroad; so do projects without permits. Every check in this guide applies equally to projects sold abroad. The law that governs your purchase is Thai law, regardless of where you signed the reservation form.
How do I verify that a building permit has actually been issued?
Ask the developer for the permit reference number and the issuing authority (municipality or district office). Give these to your Thai lawyer. The lawyer contacts the authority directly to confirm the permit is valid, covers the building as described, and has not been suspended. Do not accept a photocopy of the permit document as final verification.
What is the FET certificate and do I need it as a foreign buyer?
A Foreign Exchange Transaction (FET) certificate is issued by a Thai commercial bank when you transfer foreign currency into Thailand for a property purchase. It records the amount, currency, and purpose. You need this document to register a condominium title in your name at the Land Department and to repatriate the proceeds when you later sell. Transfer funds as foreign currency, not Thai baht, and instruct your Thai bank to issue the FET certificate at the time of transfer.
Can a litigation check catch all risks linked to a Thai developer?
A litigation check identifies active and concluded court cases involving the developer's company. It does not catch disputes that have not yet reached the courts, regulatory penalties, or issues with related companies under different names. Combine the litigation check with forum research, DBD registration review, and the completed-project track record check for a fuller picture.
How much does full legal due diligence on a Thai property cost?
Indicatively, in 2026, full due diligence including title search, permit verification, litigation check, and SPA review costs 30,000-80,000 THB depending on the province, the complexity of the title structure, and the number of documents reviewed. This is separate from transfer fees and taxes. Budget for it as a fixed line item from the start.
