Checking Thai Developer Financial Stability: 7 Verifiable Steps
By THAI.ESTATE Editorial Team14 min read
Before you transfer a single baht to a Thai developer, you need to know whether that company can finish what it has started. Developer insolvency mid-construction is the single largest financial risk for foreign buyers in Thailand. The good news is that several checks are fully verifiable, some from your home country, and others require a licensed Thai lawyer on the ground.
This guide gives you a step-by-step verification playbook. It defines red-flag thresholds, not vague warnings, and explains exactly what each failure costs when ignored.
Quick answer
- Register of companies: Check the developer's registered capital, shareholders and financial filings at the Thai Department of Business Development (DBD) online portal. A company with registered capital under 10 million THB building a 500-unit tower is a red flag.
- Land title class: The project land must carry a chanote (Nor Sor 4 Jor) - full ownership title. Lower-grade titles (Nor Sor 3 Gor, Sor Kor 1) cannot legally underpin a condominium or villa project sold to foreign buyers.
- Building permit and EIA: For projects above 10,000 sqm or in environmentally sensitive zones, an Environmental Impact Assessment (EIA) approval must precede construction. Verify the building permit number with the local municipality (OrBorTor or city hall).
- Construction financing: A financially stable developer funds construction from a bank construction loan, not solely from buyer instalments. Ask for written confirmation of the credit facility.
- Payment schedule tied to milestones: Responsible developers link payment stages to verifiable construction progress - foundation, structure, fitout, transfer. Any schedule demanding more than 30-40% of the purchase price before the structure is visibly above ground is a red flag.
- Litigation history: Search the Thai Court system (available in Thai via the Court of Justice portal) or instruct a lawyer to check for civil or criminal cases against the developer entity.
- Completed projects: Visit or independently inspect at least two completed projects by the same developer. Delays of more than 18 months on previous projects signal systemic financing problems.
Options and scenarios
How do I check a Thai developer's track record from abroad?
You can access the Thai Department of Business Development (DBD) portal at dbd.go.th. Search by the developer's company name (you need the Thai legal name, not the project brand name - ask the sales team for it). The portal shows date of incorporation, registered capital, list of directors and, for companies that file accounts, annual financial statements.
Registered capital alone is not a complete picture of financial health, but it is your first filter. For a condominium project with a projected revenue of 1 billion THB, a developer with only 1-2 million THB registered capital has a thin legal buffer if construction costs overrun.
For completed project history, search the project name plus the word 'review' or 'delay' in English and Thai on Thai property forums. Cross-reference delivery dates in old marketing materials (available via the Wayback Machine archive) against actual handover dates reported by buyers.
What does construction financing actually look like for a legitimate developer?
A financially sound Thai developer will have one or more of the following:
- A bank construction loan (a Thai commercial bank, not a shadow lender) approved before or shortly after launch. Banks conduct their own due diligence on title and permits before lending. If a major Thai bank has extended credit, it has already verified the chanote and basic permit status.
- Pre-sales as a planned proportion of total project cost, typically 30-50%. This is normal and expected. The red flag is when pre-sales appear to be the only source of funds - meaning your instalments are paying for earlier buyers' units.
- Equity from the parent company or group. Developers that are subsidiaries of listed companies (Stock Exchange of Thailand, SET) must disclose project financing in their filings. You can read these at set.or.th in English for SET-listed entities.
Always ask the sales team directly: 'Which bank holds the construction loan for this project?' A legitimate project will have a named bank. If the answer is vague or changes, treat it as a serious concern.
How do I verify the land title behind the project?
The chanote (officially Nor Sor 4 Jor) is the only land title that gives the holder full legal ownership rights and can be subdivided or used as collateral. Before signing any reservation agreement, ask for a copy of the chanote document for the project land.
A lawyer can then verify this document directly at the relevant Land Office (Samnakngan Thi Din). The Land Office will confirm that:
- The title matches the physical plot
- The developer (or a related entity with a disclosed relationship) is the registered owner
- There are no encumbrances, mortgages or liens that could block transfer
This verification costs approximately 5,000-15,000 THB in lawyer fees and typically takes 1-3 business days. It is not optional.
If the project land carries a Nor Sor 3 Gor title, the developer must upgrade it to a chanote before condominiums can be registered. Ask for a timeline and verify progress. If the land carries a Sor Kor 1 (acknowledgement of possession) document, walk away. This document does not grant ownership and cannot legally support a foreign-purchasable condominium.
How do I check EIA approval and the building permit?
For condominium or residential projects in Thailand that exceed 10,000 square metres of usable area, or that fall within 50 metres of a beach or national park boundary (or other sensitive zones defined under the National Environmental Quality Act), an EIA approval from the Office of Natural Resources and Environmental Policy and Planning (ONEP) is mandatory before construction begins.
Building permits are issued by the local administrative authority - the OrBorTor (Tambon Administrative Organisation) in rural or resort areas, or by the city hall in Phuket, Pattaya, Bangkok or Chiang Mai.
To verify:
- Ask the developer for the EIA reference number and the building permit number.
- Instruct your lawyer to confirm both with the issuing authorities.
- Check whether the building permit matches the number of floors and units being sold. Permits sometimes cover fewer floors than the sales renders show.
A project being sold on the basis of 'permits pending' has no legal right to build yet. Any payment made before permits are confirmed is unsecured.
What payment schedule protects me most?
In Thailand, there are no escrow accounts for foreign property buyers in the traditional sense. Your real protection is a payment schedule contractually tied to construction milestones, combined with penalty clauses for developer delay.
A standard, buyer-protective schedule for an off-plan condominium looks like this:
- Reservation deposit: 50,000-200,000 THB (refundable if due diligence fails, but confirm this in writing)
- Contract signing: 10-20% of purchase price
- Foundation completed: 10-15%
- Structure completed (roof level): 10-15%
- Fitout/finishing: 10-15%
- Transfer of ownership: remaining 25-35%
If a developer asks for 50% or more at contract signing for an early-stage project, that is a red flag. It suggests the company needs your money to start construction rather than to complete it.
Your contract should include a delay penalty clause specifying a daily or monthly financial penalty (commonly 0.01-0.05% of the purchase price per day) if the developer misses agreed handover dates. Without this clause, you have no financial remedy for delays short of litigation.
How do I find litigation history for a Thai developer?
Thailand's Court of Justice (coj.go.th) has a case search function, primarily in Thai. An English-language search is not available, so this step requires a Thai lawyer or a bilingual researcher.
Ask your lawyer to search for:
- Civil cases brought by previous buyers against the developer company (breach of contract, failure to transfer title)
- Cases involving the land plot itself (ownership disputes, boundary conflicts)
- Tax or Revenue Department enforcement actions
- Bankruptcy or rehabilitation proceedings under Thailand's Bankruptcy Act
A single case from a dissatisfied buyer five years ago is not necessarily disqualifying. A pattern of multiple buyer claims, or any current insolvency proceeding, is disqualifying.
What can I realistically verify online versus on the ground?
Some checks are accessible from abroad; others are not. Knowing the difference saves you time and prevents false reassurance from incomplete information.

Risks and mistakes
Paying more than 30% before a building permit is issued
This is the most common and most costly mistake. If a developer has no building permit, it has no legal right to construct. Authorities can halt construction at any point. You have no legal claim to a physical asset - only a contractual claim against a company that may not have the funds to repay you. Market estimates suggest that several thousand foreign buyers in Thailand have been caught in exactly this situation over the past decade. Recovery through Thai courts is possible but typically takes three to five years and requires Thai legal representation throughout.
Accepting project-branded land documents as proof of chanote
Some developers show buyers a coloured project brochure with a map overlay and describe it as 'title documentation'. A chanote is a specific government-issued document with a reference number, an official stamp and a plot map. It is not a marketing document. Never accept anything except the original chanote document, verified at the Land Office.
Ignoring registered capital relative to project size
A company with 2 million THB registered capital is legally capable of selling a 1 billion THB condominium project in Thailand. There is no minimum capital-to-project-size ratio required by Thai law as of 2026. This means you must apply your own filter: if the developer's balance sheet is thin relative to the project's total development cost, the financial buffer against cost overruns is thin too.
Signing a contract without a delay penalty clause
Without a written delay penalty, a developer who delivers 24 months late owes you nothing beyond eventually completing the unit. Thai courts will enforce penalty clauses that are in the signed contract. They cannot create remedies that the contract does not specify. A standard penalty of 0.01% of the purchase price per day on a 5 million THB unit equals 500 THB per day - not generous, but better than zero.
Relying solely on the sales agent's due diligence
The sales agent earns a commission when you buy. Their incentive is not aligned with yours at the due diligence stage. Use the sales agent for project information and introductions, but conduct all title, permit and financial checks through an independent lawyer whom you hire and pay directly.
Treating renders and show units as proof of delivery capacity
A photorealistic render costs a developer approximately 50,000-200,000 THB to produce. A furnished show unit costs perhaps 2-5 million THB. Neither tells you whether the developer can raise 500 million THB in construction financing. Judge financial capacity by documented evidence - bank letters, SET filings, DBD accounts - not by marketing materials.
FAQ
How do I find a Thai developer's official company registration?
Go to dbd.go.th and use the company search function. You need the Thai legal name of the developer entity, not the project brand name. Ask the sales team for the exact Thai company name and registration number. The portal is free and accessible from outside Thailand.
Is a large number of sold units proof that a developer is financially stable?
No. High sales volume means the developer has collected buyer deposits and instalments. It does not confirm that construction is fully funded or that the company is solvent. Some developers use new project sales to cover debts from earlier projects. Check the completed project record and construction loan separately.
What is a chanote and why does it matter for my purchase?
A chanote (Nor Sor 4 Jor) is Thailand's highest class of land title document. It gives the holder full legal ownership rights and is the only title class that can be subdivided and used as collateral for a construction loan. A condominium unit can only be registered and transferred to a foreign buyer if the underlying land holds a chanote. Lower-grade title documents cannot legally support this process.
Can I verify a building permit online from my home country?
Not directly. Building permits in Thailand are issued by local authorities, and their databases are not publicly accessible online in English. You need a lawyer or a local representative to physically verify the permit at the relevant OrBorTor or city hall. Your lawyer can then send you a scanned copy and a written confirmation.
What is the EIA requirement and which projects need it?
An Environmental Impact Assessment (EIA) is a government review of a project's environmental impact. In Thailand, it is mandatory for residential projects above 10,000 square metres of usable area, and for any development within environmentally sensitive zones (beaches, national parks, certain hillside areas). The EIA must be approved by ONEP before construction legally begins. If a project in a beach resort area started construction without a disclosed EIA, it is operating in breach of environmental law.
What financial documents should I ask a Thai developer to provide?
Ask for: the developer company's DBD registration and most recent filed accounts; a letter from the construction finance bank confirming the credit facility and its amount; the building permit document; the EIA approval reference (if applicable); the chanote reference for the project land; and the sale and purchase agreement draft before signing. A developer who refuses to provide any of these documents is signalling that something is not in order.
How much of the purchase price should I pay before construction is finished?
As a general guideline based on standard market practice, you should not pay more than 50-60% of the total purchase price before the building structure is completed and verified. The remaining 30-40% should be held back until transfer of ownership (title registration in your name or in the name of your company, for villa purchases). This structure gives you leverage if the developer underperforms.
What happens if a Thai developer goes bankrupt before completing my unit?
You become an unsecured creditor of the developer company. Thailand's Bankruptcy Act allows for rehabilitation proceedings, in which a court-appointed planner tries to restructure the company and complete the project. This process can take three to seven years. Recovery of your full investment is not guaranteed. This is why front-loaded payment schedules are dangerous: the more you have paid before completion, the more you stand to lose.
Does a SET-listed developer automatically mean lower risk?
Being listed on the Stock Exchange of Thailand (SET) requires audited annual accounts, quarterly disclosures and regulatory oversight. This makes financial information more accessible and reduces (but does not eliminate) the risk of undisclosed insolvency. A SET-listed developer has more reputational and regulatory pressure to complete projects. It is a meaningful positive signal, not a guarantee.
What is the realistic total cost of independent due diligence in Thailand?
Budget approximately 20,000-50,000 THB (indicative figures as of 2026) for a thorough independent due diligence covering company search, chanote verification, permit checks and a contract review by a qualified Thai lawyer. On a 5 million THB purchase, this represents 0.4-1.0% of the purchase price. It is the most cost-effective insurance you can buy.
