Vetting a Phuket Developer: 8 Steps to a Safe Property Deal in 2026

At least four residential projects on Phuket were frozen in recent years, with buyers losing between 3 and 18 million baht each. In every case, the root cause was identical: money transferred to a developer nobody had properly checked.

The problem is not a shortage of reputable builders on the island. Solid developers exist. The problem is that foreign buyers rarely know where to look or what to verify. Thai business registries are public, financial statements are accessible, and construction licences can be confirmed in under 20 minutes. Yet most buyers never bother. This guide gives you a concrete eight-step checklist that eliminates roughly 95% of purchase risk before you ever sign a contract.

Quick Answer

• Phuket has more than 200 registered development companies, but only around 30 have delivered completed projects in the past five years
• Checking a company through Thailand's DBD (Department of Business Development) takes 15-20 minutes and costs nothing online
• A credible condominium developer should carry a paid-up capital of at least 20 million baht
• An EIA (Environmental Impact Assessment) is legally required for projects exceeding 79 units or buildings taller than 23 metres
• Construction permits (Ror. 1 / Ror. 4) are verified at the local municipality - either Or Bor Tor or Tessaban
• Industry estimates suggest 60-70% of frozen Phuket projects belonged to companies with registered capital below 5 million baht

Scenarios and Options

Step 1 - Company Registration Check via DBD

Visit the Department of Business Development portal at dbd.go.th. Enter the company name or registration number. The database returns the incorporation date, registered capital, director names, and current company status (active or dissolved). A company registered less than three years ago with capital of only 1-2 million baht is a yellow flag. That structure is typical of single-purpose SPV vehicles created for one project and easily abandoned when things go wrong.

Step 2 - Financial Statements

Thai companies are legally required to file audited accounts annually. Through the same DBD portal you can request the balance sheet and income statement for the past three years. Focus on three indicators: the debt-to-equity ratio, whether operating cash flow is positive, and revenue trend. A developer posting three consecutive years of losses while launching a new project is a serious red flag.

Step 3 - Completed Project Portfolio

Ask for a full list of delivered projects with completion dates, then verify them physically. Visit the sites, speak to residents, and inspect common areas. A developer that has completed five or more projects over the past decade, all of which are operational, is a strong positive signal. Companies with zero or one delivered project carry materially higher risk.

Step 4 - Land Title Verification

At the Land Department (Krom Tee Din) confirm who actually owns the land under the planned development, and check for any mortgages, encumbrances, or active litigation. Critically, ensure the plot is held under a Chanote title (Nor Sor 4 Jor) - the only fully recognised Thai land title. Parcels with Nor Sor 3 or Sor Kor 1 titles create legal complications for condominium registration.

Step 5 - Construction Licence (Ror. 4)

The municipality issues the formal building permit, called a Ror. 4 or Bai Anuyat Kor Sang. Without it, construction is illegal. Verify that the licence covers exactly the project being marketed, and that the approved parameters - floors, total area, unit count - match the developer's sales materials. Developers who begin selling units before obtaining this permit are in violation of Thai law.

Step 6 - Environmental Impact Assessment (EIA)

For larger developments (over 79 units or buildings exceeding 23 metres), Thai law mandates an Environmental Impact Assessment. The approval process takes 6-12 months. If a developer is selling units in a sizable complex where EIA approval has not yet been granted, the project can be blocked indefinitely. Always request the EIA reference number and cross-check it through ONEP (Office of Natural Resources and Environmental Policy and Planning).

Step 7 - Contractor Licence Check

The developer and the construction contractor are often different entities. Find out who will actually build. Major Thai contractors holding a 'Piset' category licence from DPT (Department of Public Works and Town and Country Planning) are authorised to handle projects of unlimited value. Contractors with Category 1-3 licences are capped at lower project values. A mismatch between the contractor's licence grade and the project scale is a compliance violation worth flagging.

Step 8 - Independent Legal Review of the Contract

Engage an independent lawyer - not one recommended by the developer. Key clauses to scrutinise: payment instalments tied to construction milestones rather than calendar dates; specific financial penalties for construction delays; and clearly defined refund conditions if the developer fails to deliver. Expect to pay 15,000-30,000 baht for this review. It is the best-value expenditure in the entire transaction.

Main Risks and Mistakes

Mistake 1 - Trusting renders and showrooms. High-end 3D visualisations carry no legal weight. The only binding documents are the sale and purchase agreement and its technical specification annexes.

Mistake 2 - Checking the developer but not the land. A developer may appear financially solid while the project land is mortgaged to a bank. If the developer defaults on that loan, the bank can seize the plot along with your future unit.

Mistake 3 - Paying 100% before construction completes. The standard payment structure on Phuket runs roughly as follows: 30% on contract signing, 30% at structural frame completion, 10% at fit-out stage, and 30% on handover. Any schedule that front-loads payments beyond this norm warrants serious caution.

Mistake 4 - Overlooking the foreign ownership quota. Thai condominium law limits foreign freehold ownership to no more than 49% of total unit floor area in any single building. Once that quota is exhausted, you cannot register freehold title. Confirm the current foreign quota percentage with the developer and independently verify it at the Land Department.

Mistake 5 - Skipping independent legal counsel. The developer's lawyer works for the developer. That is not a conflict of interest - it is simply how legal representation works. Your lawyer must be entirely independent and retained by you.

FAQ

Where can I check a Thai developer for free? Use the DBD data warehouse at datawarehouse.dbd.go.th. Registration data, share capital, director details, and audited financial statements for all registered Thai companies are publicly accessible.

How much does a full due diligence review cost? Typically between 30,000 and 80,000 baht depending on project complexity. A thorough review covers company registration, land title, licences, and contract analysis.

What is the EIA and when is it required? An Environmental Impact Assessment evaluates a project's environmental footprint. It is mandatory for condominiums with more than 79 units or buildings taller than 23 metres. A project lacking EIA approval cannot legally proceed to construction.

Can I verify a construction permit on my own? Yes. Contact the relevant local municipality - Or Bor Tor for sub-district areas or Tessaban for urban areas - and provide the project name. The information is available on request.

Is there a legal minimum capital requirement for developers? No statutory minimum exists specifically for property developers in Thailand. In practice, however, a developer launching a 500-million-baht project with registered capital below 20 million baht is structurally undercapitalised - and that is a serious concern.

What if the developer refuses to share financial statements? Request them directly through DBD. If the company has failed to file audited accounts, it is already in violation of Thai law - and that alone is a sufficient reason to walk away from negotiations immediately.

How do I check whether the project land is mortgaged? At the Land Department, using the Chanote title number, you can obtain a full title extract showing all encumbrances, mortgages, and third-party rights registered against the plot.

Does a large brand name guarantee investment safety? It reduces risk but does not eliminate it. Developers listed on the Stock Exchange of Thailand (SET) are required to disclose financial information publicly, which adds a meaningful layer of transparency compared to private companies.

Should I buy from a developer with no completed projects? Only if the company's shareholders have verifiable capital and a proven construction track record, and independent due diligence finds no issues. For conservative investors, the answer is generally no.
