Vetting a Phuket Developer: 7 Steps Before You Sign Any Contract
In 2026, at least 12 residential projects on Phuket failed to deliver on schedule in recent years - and buyers paid the price with lost deposits, wasted months, and unresolved legal disputes. In the vast majority of cases, the root cause was identical: no one checked the developer before signing.
Phuket's property market is running hot. New developers appear every quarter, and separating a credible company with a real delivery track record from a shell entity with no construction experience is far harder than it looks. This guide gives you a concrete, step-by-step due diligence framework that protects your capital before you commit a single baht.
Quick Answer
- Phuket has more than 200 active development companies registered as of 2026, but fewer than 40 have completed at least three projects
- Verifying a company's legal status through the Department of Business Development (DBD) takes 15 minutes online and costs nothing
- A construction permit (Ror. 4 / อ.4) is issued by the local municipality and confirms the project meets building code requirements
- A developer's financial health can be assessed through its balance sheet and profit-and-loss statement filed in the DBD registry
- An Environmental Impact Assessment (EIA) is mandatory for condominium projects with more than 80 units or buildings taller than 23 metres
- Industry estimates suggest 30-40% of project delays are linked directly to insufficient developer financing
Scenarios and Options
Scenario 1: Buying from a Large Developer with a Track Record
The developer has operated in Phuket for more than 10 years, delivered five or more projects, and maintains publicly available financial reporting. You pay a market premium of roughly 10-15%, but you get a predictable outcome. Due diligence here focuses on confirming current licences and speaking with residents of already-completed communities.
Scenario 2: Mid-Tier Developer with One to Three Completed Projects
The company has existed three to seven years and delivered one to three projects. Prices are typically 5-10% below market leaders. At this tier, it is critical to investigate whether previous projects were delayed, whether the developer has secured bank-backed project financing, and who the main construction contractor is.
Scenario 3: New Developer with No Portfolio
The company registered less than two years ago and has no completed projects. The discount to market can reach 15-25%, but the risk profile is at its highest. You should require written confirmation of project financing from a major Thai bank - Kasikorn, Bangkok Bank, or SCB. Without that confirmation, do not place a deposit.
| Parameter | Large Developer (10+ years) | Mid-Tier (3-7 years) | New Developer (under 2 years) |
|---|---|---|---|
| Completed Projects | 5 or more | 1-3 | 0 |
| Price vs. Market | +10-15% premium | 5-10% discount | 15-25% discount |
| Delivery Delay Risk | Low | Medium | High |
| Project Financing | Almost always | Often | Rarely |
| Due Diligence Depth | Basic | Extended | Maximum |
| Best Suited For | First-time buyers | Experienced investors | Legal professionals only |
Step 1 - Company Registry Check via DBD Online
Visit datawarehouse.dbd.go.th and enter the company name in Thai or its Tax ID number. The portal displays the registration date, registered capital, director names, and the most recent financial statements. A company with registered capital of 2 million baht constructing a 500-million-baht project should prompt serious questions before you proceed.
Step 2 - Construction Permit (Ror. 4)
Request a copy of the construction permit from the developer. This document is issued by the local municipal authority - either a Tessaban or an OrBorTor. Confirm that the company name on the permit matches the entity selling the unit. Also check the expiry date: Ror. 4 permits are valid for one year and must be renewed for ongoing construction.
Step 3 - EIA Approval (Where Applicable)
For larger condominium projects, the EIA report must be approved by Thailand's Office of Natural Resources and Environmental Policy and Planning (ONEP). A project without an approved EIA can be halted at any stage of construction. Ask the developer for the EIA approval number and verification date, then cross-check it at eia.onep.go.th.
Step 4 - Visit Completed Projects in Person
Drive to communities the developer has already handed over. Pay attention to the condition of common areas two to three years post-completion, any visible cracking or drainage problems, the responsiveness of the juristic person (management office), and resident feedback in Facebook groups and property forums.
Step 5 - Land Title Verification
Request a copy of the Chanote (Nor Sor 4 Jor) for the project land. At the Phuket Land Office you can confirm whether the developer owns or leases the land, whether any mortgages, liens, or legal disputes are registered against it, and whether the land designation permits residential construction. An official title extract costs 100-200 baht.
Step 6 - Project Financing from a Thai Bank
A developer that has secured a construction loan from a Thai bank has already passed that institution's internal due diligence review. This is not a guarantee of completion, but it is a meaningful filter. Thai banks require verification of land title, licences, financial modelling, and management experience before approving project loans. Ask the developer directly: 'Which bank is financing this project?'
Step 7 - Independent Legal Audit
Engage a Thai lawyer who has no affiliation with the developer or the sales agent. A full legal review - covering company verification, title search, and purchase agreement review - costs between 30,000 and 80,000 baht depending on complexity. That represents roughly 0.5-1% of a typical Phuket apartment price and is the most effective insurance you can buy for your investment.
Main Risks and Mistakes
1. Trusting the showroom over the financials. A marble-clad sales office says nothing about the company's solvency. Review the balance sheet, not the interior design.
2. Signing a Thai-language contract without a certified translation. The Thai version always takes legal precedence. Require a certified translation and document any discrepancies before you sign.
3. Sending payments to a personal bank account. All payments must go directly to the developer company's registered corporate account. A transfer to a director's personal account or an agent's account is a serious red flag.
4. Ignoring the payment schedule structure. Reputable developers tie instalment payments to verified construction milestones - foundation, structure, finishing. A scheme demanding 70% of the purchase price at reservation, with no link to construction progress, carries extreme risk.
5. Accepting a contract with no delay penalty clause. Your purchase agreement must include a compensation clause for late delivery. The Thai market standard is 0.01% of the purchase price per day of delay.
6. Buying from a company with a persistently negative balance sheet. If the DBD financial records show losses over three or more consecutive years, the developer may lack the resources to bring the project to completion.
FAQ
Where can I check a Thai developer for free? At the Department of Business Development portal: datawarehouse.dbd.go.th. The registry provides financial statements, director information, registration date, and registered capital at no charge.
How much does a legal due diligence review cost in Phuket? Between 30,000 and 80,000 baht for a full package covering company verification, land title search, and sale-and-purchase agreement review.
Which document confirms a developer's right to build? The construction permit Ror. 4 (อ.4), issued by the local municipal authority. Without this permit, any construction on the site is illegal.
What is a Chanote and why does it matter? A Chanote (Nor Sor 4 Jor) is the highest form of land title in Thailand. It confirms full ownership rights with GPS-precise boundary coordinates. Checking it reveals registered encumbrances, mortgages, and ongoing disputes.
Are Thai developers required to publish financial reports? Yes. All Thai companies must file annual financial statements with the DBD, and those filings are publicly accessible. If a company has not filed for two or more years, it may be in the process of dissolution.
What does bank-backed project financing actually mean? It is a construction loan extended by a bank specifically for the development project. The bank has independently reviewed the developer, the land title, the licences, and the financial model. Its presence reduces the risk of an incomplete build.
Can I check whether a developer has been involved in court cases? Yes. The Courts of Justice information system at cios.coj.go.th allows searches by company registration number or Thai-language company name.
How can I find out how many units have already sold? Request a sales report directly from the developer, then cross-check with independent agents and the Land Office. Pre-construction sales of 50% or more before groundbreaking is a positive market signal.
Should I buy from a developer with no completed projects at all? Only if the developer can demonstrate confirmed project financing from a major Thai bank and only after a full independent legal review. Without both conditions, the risk does not justify even an attractive entry price.
Thorough developer due diligence in Phuket is not excessive caution - it is standard capital protection. The 7 steps outlined above typically take two to four weeks and cost 30,000-80,000 baht. Compare that figure with what you stand to lose if you skip them.
