How to Verify a Developer's License in Thailand: 7 Essential Steps

In recent years, several developer companies on Phuket collapsed — leaving buyers with neither their money nor their units. One project alone collected over 480 million baht in deposits before vanishing entirely. Every one of these companies looked credible: polished websites, sleek showrooms, billboard advertising across the island. The buyers who lost everything had one thing in common — none of them spent even an hour verifying the developer's credentials before signing.

Verifying a developer in Thailand is not a formality. It is your only real line of defense. Unlike many Western markets, Thailand offers no automatic buyer protection mechanisms, no government-backed insurance schemes, and no fast-track refund processes. The rule here is simple: verify before you transfer, because once the money is gone, recovery is a long and uncertain road.

Quick Answer

  • Every legitimate developer in Thailand must be registered with the Department of Business Development (DBD) — free to check at datawarehouse.dbd.go.th

  • Condominium developments require an EIA (Environmental Impact Assessment) approval and a construction permit issued by the local municipality

  • Company financial statements can be ordered from the DBD for 500 baht — covering assets, liabilities, revenue, and profit or loss

  • Under the Condominium Act B.E. 2522, developers must register a project before sales can legally begin

  • Phuket has issued over 120 new residential construction permits in recent years, but a significant share of those projects have not reached completion

  • The average construction timeline for a Phuket condominium is 24 to 36 months — any delay exceeding 6 months is a serious warning sign

Scenarios and Options

Step 1 — Verify Company Registration via DBD

Go to datawarehouse.dbd.go.th and search by company name or registration number. The database will return the registration date, registered capital, director names, and legal address. If the company does not appear in the registry, walk away immediately.

Pay close attention to registered capital. A developer with 1 million baht in registered capital promising to deliver a 500-million-baht project is a major red flag. Credible developers register capital that is proportionate to the scale of their developments.

Step 2 — Request the Construction Permit

Every project must hold a valid ror. 1 construction permit issued by the relevant local authority — Tessabaan or OrBorTor. Ask the developer for a copy. If they refuse or delay, treat that as a second red flag.

The permit specifies the building type, number of floors, total floor area, and the name of the landowner. Cross-reference those details against what the developer is presenting in their marketing materials.

Step 3 — Confirm the EIA for Larger Projects

Any project with more than 80 units or a building height exceeding 23 meters is legally required to complete an Environmental Impact Assessment. EIA reports are published on the website of the Office of Natural Resources and Environmental Policy and Planning (ONEP). A large-scale project without a completed EIA is operating illegally — full stop.

Step 4 — Review the Financial Statements

Order a copy of the company's financial report from the DBD for 500 baht. Key indicators to examine:

  • Debt-to-asset ratio — if liabilities exceed 70% of total assets, the company is in a vulnerable position
  • Cash flow — three consecutive years of negative operating cash flow is a serious warning sign
  • Profitability — a loss-making company launching a new project is a classic pattern associated with high-risk or fraudulent operations

Step 5 — Review the Developer's Track Record

Ask the developer for a list of completed projects, then independently verify:

  • Were those projects delivered on schedule? (Ask residents, check Facebook groups and property forums)
  • Are the individual units registered with the Land Department (Land Office)?
  • Are there any complaints filed with the Office of Consumer Protection Board (OCPB)?

A developer with three or more successfully completed projects represents a substantially lower risk than a first-time developer relying on attractive renders.

Step 6 — Verify Land Title Ownership

The land beneath the development must carry a Chanote (Nor Sor 4 Jor) title deed — this is the only fully recognized form of land ownership in Thailand. Other document types such as Nor Sor 3 or Nor Sor 3 Gor carry limited rights and introduce legal exposure.

Engage a qualified lawyer to verify the land title directly with the Provincial Land Office. This verification typically costs 3,000 to 5,000 baht and should also confirm whether any mortgages, liens, or encumbrances are registered against the land.

Step 7 — Hire an Independent Lawyer

This is not optional — it is essential. A qualified Thai property lawyer should:

  • Review all documentation from Steps 1 through 6
  • Examine the sale and purchase agreement for any unfair or one-sided clauses
  • Confirm that the payment schedule is tied to clearly defined construction milestones
  • Verify that the contract includes enforceable provisions for refunds in the event of developer default or significant delays

Full due diligence legal services in Phuket typically cost between 30,000 and 60,000 baht, depending on project complexity.

Main Risks and Mistakes

Mistake 1 — Trusting the brochure. Glossy renders and polished marketing materials carry no legal weight. The only documents that matter are the permits, the title deed, and the signed contract.

Mistake 2 — Paying 100% upfront. Standard market practice in Thailand structures the booking deposit at 50,000 to 200,000 baht, with remaining payments tied to construction milestones. Any developer demanding full payment before construction begins is exhibiting behavior consistent with fraud.

Mistake 3 — Skipping the lawyer to save money. A due diligence fee of 30,000 to 60,000 baht can protect an investment of 5 to 20 million baht. That is a protection ratio of roughly 1 to 300 — one of the most cost-effective risk management decisions an investor can make.

Mistake 4 — Relying solely on online research. A physical visit to the construction site is non-negotiable. Check whether heavy machinery is present, whether workers are active, and whether the mandatory permit signboard is displayed on-site.

Mistake 5 — Overlooking legal disputes. Check both the company and its directors through the Thai Court of Justice system for any ongoing litigation or previous judgments.

FAQ

How do I verify a developer's registration in Thailand online? Visit datawarehouse.dbd.go.th and search using the company name in Thai or English. The result will show registration status, registered capital, and director details.

Is a construction permit required for a villa in Phuket? Yes. All construction in Thailand requires a permit from the relevant local authority. For villas, this is the ror. 1 form. Building without this permit is illegal and the structure may be subject to demolition orders.

How much does developer due diligence cost in Thailand? Basic online checks are free. A full professional due diligence review through a qualified lawyer costs between 30,000 and 60,000 baht — approximately 800 to 1,700 USD.

What can I do if a developer fails to complete a project? File a complaint with the OCPB (Office of Consumer Protection Board) and consult a lawyer about civil litigation options. Be prepared for a process that can take one to three years to resolve — which is precisely why pre-purchase verification matters so much.

Can I recover money if a developer goes bankrupt? Recovery is theoretically possible through bankruptcy proceedings, but practically difficult. Individual buyers typically rank behind secured creditors such as banks and tax authorities. Average recovery rates tend to fall in the range of 10 to 30% of the original investment.

How do I confirm a project has a valid EIA? Check the ONEP website directly, or request the EIA certificate from the developer. Any project with more than 80 units that cannot produce a valid EIA is operating outside the law.

What is the most reliable land title in Thailand? Only Chanote (Nor Sor 4 Jor) confirms full ownership rights with GPS-verified boundaries. All other title types carry limitations and should be treated with caution.

How do I find out if land is mortgaged or encumbered? Encumbrance searches are conducted at the Provincial Land Office. A lawyer can obtain a certified extract showing all registered mortgages, easements, and legal restrictions on the land.

Should I buy from a developer with no completed projects? This carries significant risk. If you proceed, ensure the payment schedule is strictly milestone-based and that the contract contains clearly worded and enforceable refund provisions.

Verifying a developer in Thailand takes between 7 and 14 days and costs no more than 65,000 baht for a complete professional review. For any investment measured in millions, that is not an expense — it is the most rational decision you can make before committing your capital.
