How to Check a Thai Developer's Reputation: 7 Verified Steps
By THAI.ESTATE Editorial Team13 min read

Checking a Thai developer's reputation before you pay anything is not optional. It is the single most important step in a Thai property purchase. Thailand has no central developer-rating body, no mandatory escrow protection for buyers, and no automatic refund mechanism if a project fails. Your money is at risk from the moment you sign a reservation agreement.
The good news: most of the information you need is public, structured, and checkable from abroad. You need a combination of online research, document requests, and a licensed Thai lawyer on the ground. This guide gives you a step-by-step verification playbook for 2026.
Quick answer
- Check completed projects first. A developer with zero finished buildings carries the highest risk, regardless of how polished their marketing is.
- Request the land title document (chanote). A chanote is a fully registered land title with GPS coordinates at the Land Department. Lower-grade titles - Nor Sor 3, Sor Kor 1 - carry legal risk for a condo or villa project.
- Confirm the building permit and EIA. No permit means no legal right to build. Renders sold before a permit is issued are a defined red flag.
- Ask how construction is financed. Projects funded entirely from buyer instalments (not a bank construction loan) face a higher collapse risk if pre-sales slow.
- Map the payment schedule to construction milestones. A legitimate developer links each payment to a verifiable stage: foundation complete, structure complete, handover. Front-loaded schedules that demand 50% or more before construction starts are a warning sign.
- Check litigation history at the Civil Court. Your lawyer can run a name search on the developer company at the Thai Courts system.
- Budget THB 30,000 to THB 60,000 for a due-diligence lawyer. This is indicative for 2026. It is your cheapest insurance.
Options and scenarios
Scenario 1: You are buying from abroad, pre-launch, from a developer you found online
This is the highest-risk scenario. You have no local contacts, no completed reference projects to visit, and the developer may be offering significant early-bird discounts to attract deposits before permits are in place.
What to do:
- Refuse to pay anything before your lawyer has seen the land title and confirmed the project's permit status.
- Ask the developer for the company registration number (registered with the Department of Business Development, DBD). Run it yourself on the DBD e-Service portal (www.dbd.go.th), which is free and accessible in English. You will see paid-up capital, director names, and filing history.
- Request a list of completed projects with addresses. Visit them on Google Street View or ask your lawyer to do a physical inspection.
- Ask for the EIA approval reference number if the project is above the threshold size (generally condominiums above a certain floor area or unit count in sensitive zones require an Environmental Impact Assessment under Thai law - your lawyer will confirm the threshold for your specific project).
- Do not rely on the developer's own documents alone. Cross-check every document at the relevant government office.
Scenario 2: You are buying a resale unit in a completed condo from an individual seller
Risk is lower but not zero. The project is built, but the juristic person (the condominium's management body, established under the Condominium Act) may have financial problems, accumulated debt, or unresolved structural defects.
What to do:
- Request the juristic person's most recent financial statements and meeting minutes. You are entitled to these as a prospective buyer through a formal request.
- Check the sinking fund balance. The sinking fund is a one-time reserve payment collected at purchase (typically THB 500 to THB 700 per square metre, indicative 2026 figures) to cover major future repairs. A depleted sinking fund with no plan to replenish it is a problem.
- Confirm the seller holds a proper chanote title for the unit, not a lease or other instrument.
- Check that the 49% foreign ownership quota for the building is not already full. Your lawyer can verify this at the Land Department.
Scenario 3: You are buying off-plan from a well-known developer with multiple completed projects
This is the lowest-risk category, but 'well-known' is not the same as 'safe'. Large developers have also had project delays and financial difficulties in Thailand.
What to do:
- Apply the same document checks regardless of brand recognition.
- Review the sales and purchase agreement (SPA) for delay penalties. Thai law allows contractual penalties for late handover; a developer who refuses to include them is a red flag.
- Confirm the developer holds a bank construction loan for the project. Ask to see the loan facility letter (or a summary). A bank's credit approval means a third party has already assessed the developer's financial standing.
- Check the title is a chanote at the project level, not a leasehold land arrangement disguised as ownership.

Risks and mistakes
Paying a reservation fee before any due diligence
In Thailand, a reservation fee (typically THB 50,000 to THB 200,000, indicative) is often non-refundable once paid. Developers use this urgency to lock in buyers before documents are ready. You should treat the reservation fee as a deposit you may lose if your checks later reveal problems. Never pay it before at least confirming the company is registered and the land title exists.
Accepting 'renders as truth'
Thailand has no law that requires a developer to deliver what marketing renders show, beyond what is written in the SPA. Renders sold before a building permit is issued have no legal backing. If a unit's layout, finish level, or amenities differ from renders, you have recourse only if the SPA specifies them in writing.
Ignoring the payment schedule structure
Aggressive front-loading is the clearest financial red flag in Thai off-plan sales. A structure demanding 30% on signing, a further 30% at foundation (which may happen within 3 months), and the balance at handover gives the developer most of your money with little construction accountability. A safer structure links each payment to a verified milestone: 10 to 15% on signing, 10 to 15% at foundation, 10% at structure completion, 10% at fit-out, and the balance at handover. Deviations from this pattern require explanation.
Relying on the developer's own lawyer
Some developers offer to connect buyers with a 'recommended' law firm. That firm may have a commercial relationship with the developer. Hire your own independent lawyer. The cost is THB 30,000 to THB 60,000 for a full due-diligence review (indicative, 2026). The alternative - losing your deposit or your entire purchase price - costs far more.
Not checking the title at project level, only at unit level
In a condominium, each unit has its own title (the condominium unit title under the Condominium Act). But the underlying land the building sits on must also be a chanote. If the developer holds the land under a lower-grade title or a lease from a third party, the entire project is at legal risk. Your lawyer must check both.
Assuming a large marketing presence means financial stability
Thailand's property market has seen projects from developers with large showrooms, international marketing roadshows, and celebrity involvement fail to complete. Marketing budget is not a proxy for financial health. Check paid-up capital on the DBD portal and ask for audited financial statements.
Missing the contractual delay penalty clause
Thai law allows, but does not mandate, delay penalties in property contracts. A developer who omits a delay penalty clause from the SPA leaves you with no contractual remedy if handover is late. The standard market rate for delay penalties in 2026 is indicative at 0.01% to 0.1% of the contract price per day of delay. Push for the higher end and ensure it is capped at a meaningful percentage (for example, the right to terminate and recover payments if delay exceeds 12 months).
FAQ
How do I check a Thai developer's track record without visiting Thailand?
Start with the Department of Business Development portal (dbd.go.th) to confirm the company is registered and review its capital and filing history. Then search for the developer's completed project addresses and cross-check on satellite mapping tools. Property buyer forums in English carry useful first-hand accounts, though you should treat them as leads for further investigation, not as conclusions. For legal document checks - land title, permit status, litigation - you need a licensed Thai lawyer on the ground.
What is a chanote and why does it matter?
A chanote (also written as 'nor sor 4') is Thailand's highest-grade land title. It is issued by the Land Department, has precise GPS boundary coordinates, and can be used for mortgages, sales, and legal enforcement without restriction. Lower-grade titles such as Nor Sor 3 or Sor Kor 1 have boundary uncertainties and limited legal protections. For a condominium or villa project, you want the underlying land to be chanote. Anything less is a risk you should price carefully and discuss with your lawyer.
Can I verify a Thai developer's building permit from abroad?
Partially. You can ask the developer for the permit number and the issuing local authority (municipality or Tessakit). Your lawyer can then confirm the permit is genuine and still valid at the relevant office. You cannot independently verify this online as Thailand does not have a unified national permit database accessible to the public in 2026. If a developer refuses to provide a permit number, treat that as a significant red flag.
What payment schedule is safe for an off-plan condo in Thailand?
A safe schedule links each payment to a construction milestone you can verify: typically 10 to 15% on signing, further tranches at foundation complete, structure complete, and fit-out complete, with the largest single payment (often 20 to 30%) at handover and title transfer. Any schedule that demands 40% or more before construction starts, or that has no milestone linkage, gives the developer your money without accountability. This is the primary financial control available to you in lieu of escrow protection.
Is there any government body in Thailand that rates or licenses residential developers?
No. Thailand does not have a mandatory developer licensing or rating system at the national level as of 2026. The Real Estate Business Act requires registration for certain project types, but enforcement and public disclosure are limited. The closest practical equivalent is the DBD registration and annual financial filing, which your lawyer can interpret. There is no government-issued 'safe developer' list you can rely on.
What does an EIA approval mean and when is it required?
An Environmental Impact Assessment (EIA) is a government review of a project's environmental impact, required for certain large or sensitive developments under Thai environmental law. The Office of Natural Resources and Environmental Policy and Planning (ONEP) administers it. The threshold for a condominium requiring an EIA depends on project size, location (beach-adjacent areas have lower thresholds), and local regulations. A project that legally requires an EIA but does not have one cannot obtain a building permit legally. Your lawyer will confirm whether your specific project needs one.
How do I check if a Thai developer has been sued by previous buyers?
You cannot do this reliably from abroad. Your lawyer can search the Civil Court's case records using the developer's company name and registration number. This is a standard part of due diligence and should be included in any lawyer's scope of work. Active or recent lawsuits from buyers claiming non-delivery or defects are a serious red flag. A clean litigation record does not mean zero risk, but active cases against a developer should make you reconsider your purchase.
What happens if the developer goes bankrupt before handover?
This is one of the worst outcomes for an off-plan buyer in Thailand. You become an unsecured creditor in the bankruptcy proceedings. Recovery of funds is slow, partial, and uncertain. The practical protection is to minimise the amount paid before the building is structurally complete and to ensure your SPA gives you termination rights with payment recovery clauses if the developer breaches the agreement. A developer with a bank construction loan is somewhat more protected against collapse mid-project because the bank has its own monitoring interest, but this is not a guarantee.
What is the foreign ownership quota and how do I check it?
Under the Thai Condominium Act, foreign nationals in aggregate can own no more than 49% of the total floor area in any single condominium building. If a building already has 49% foreign ownership, you cannot take a foreign-name freehold title for any unit in it. Your lawyer verifies this at the Land Department by requesting the condominium's ownership breakdown. Some developers will tell you the quota is available; always verify independently. Buying when the quota is full means you cannot hold the unit as freehold property in your own name.
Should I use the developer's recommended lawyer?
No. A lawyer recommended by the developer has an implicit commercial conflict. Hire an independent lawyer with no referral relationship to the developer or the agent. Ask the lawyer directly: 'Do you receive any referral fee from this developer or their agent?' A reputable lawyer will answer clearly. The cost of an independent lawyer (indicative THB 30,000 to THB 60,000 for full due diligence in 2026) is small relative to the purchase price.
