How to Check Developer Reputation in Thailand: 2026 Guide
By THAI.ESTATE Editorial Team14 min read
Checking a Thai developer's reputation before you pay anything is not optional - it is the single most important step you can take to protect your money. Thailand has no government-run developer rating system and no buyer-protection fund equivalent to those in the UK or Singapore. That means the verification work falls entirely on you and your lawyer.
This guide gives you a step-by-step verification playbook you can start from abroad, tells you exactly which checks require a licensed Thai lawyer on the ground, and defines the red flags that should stop a deal before it starts.
Quick answer
- Start with the Department of Business Development (DBD) at dbd.go.th - you can search any Thai company name or registration number for free and see financial filings, registered capital, and director history
- Request the land title document (chanote) - a full-ownership title called a Nor Sor 4 Jor (chanote) is the only class that supports a condominium freehold; any weaker title class is a red flag
- Verify building permits and EIA approval before paying a reservation fee - renders sold without a building permit mean the project may never be approved as designed
- Check the developer's completed-project track record - ask for addresses of finished buildings, then physically verify or hire a local to verify that those buildings exist and were handed over on schedule
- Review the payment schedule - milestones tied to verified construction stages protect you; aggressive front-loaded schedules (more than 30-40% before foundation stage) shift all risk to you
- A licensed Thai property lawyer costs roughly THB 20,000-50,000 (indicative, 2026 market estimates) for a full due diligence report - that fee is small relative to a lost deposit of THB 500,000 or more
Options and scenarios
How do I check a Thai developer's track record from abroad?
Your first step is the Department of Business Development (DBD) database at dbd.go.th. Every legally operating Thai company must register there. Search the developer's full company name or juristic person number (a 13-digit ID). The database shows:
- Date of incorporation
- Registered share capital
- Names of current directors (positions, not personal identities you need to verify independently)
- Annual financial statements (for larger companies that are required to file)
- Any registered amendments, such as capital reductions or director changes
A developer incorporated six months ago with THB 1 million in registered capital who is selling a 200-unit condominium is a structural mismatch. Registered capital alone does not guarantee solvency, but a very low figure relative to project scale is a warning.
Next, search the developer's company name in the Civil Court's public litigation database (available in Thai at legalexecution.go.th and through the Courts of Justice portal). This requires either Thai reading ability or a local lawyer. Court records reveal unpaid debts, breach-of-contract suits from previous buyers, and creditor actions. A single small dispute is not necessarily disqualifying; multiple buyer complaints about the same developer are.
For English-language signals, search the developer name plus terms like 'delay', 'refund', 'lawsuit', or 'Thailand' in international property forums and expat community groups. These searches are not legally conclusive, but they identify patterns worth investigating further.
How do I verify the land title behind a Thai condo project?
The land title class determines whether a condominium can legally be registered in your name. Ask the developer or sales agent for a copy of the land title document before signing anything.
The classes you will encounter:
Nor Sor 4 Jor (chanote): Full ownership title, GPS-surveyed boundaries, the only title class on which a condominium license under the Condominium Act can be issued. This is what you need.
Nor Sor 3 Gor: Confirmed ownership but boundaries may not be GPS-surveyed. Upgradeable to chanote, but the process takes time and is not guaranteed.
Nor Sor 3 or Sor Kor 1: Possession certificates, not ownership titles. A project built on this land cannot grant foreign freehold. Walk away.
Your lawyer can verify the title at the local Land Department office (the Thai government agency responsible for property registration). This check confirms the title is genuine, identifies any mortgages or liens registered against the land, and confirms the developer or a disclosed landowner holds the title - not an undisclosed third party.
If the developer refuses to share the land title document reference number so your lawyer can verify it, that refusal is itself a red flag.
How do I check if a project has building permits and EIA approval?
Under Thai law, a condominium project above a certain size (generally 80 units or a building height above defined thresholds, though specifics depend on the province and building type) requires an Environmental Impact Assessment (EIA) approval from the Office of Natural Resources and Environmental Policy and Planning (ONEP) before a building permit can be issued.
A building permit is issued by the local administrative authority - the municipality or provincial office. Ask the sales team for the building permit number and EIA reference number. Your lawyer can confirm both at the issuing office.
Why this matters: Developers in Thailand legally sell units off-plan before permits are obtained. If permits are not in place at the time of your purchase, construction can be delayed for years or blocked entirely if EIA is rejected. Projects sold heavily from renders without disclosed permit status carry significant regulatory risk.
The practical check: if the developer cannot provide a building permit number, ask when they expect to receive it and make any meaningful payment milestone contingent on that event. Put this in writing in the sale and purchase agreement.
How do I assess construction financing?
Ask the developer directly: 'Is this project financed by a Thai bank construction loan?' A Thai bank construction loan means a licensed Thai bank has done its own due diligence on the developer, the land title, and the project viability before advancing funds. That is an independent layer of verification you benefit from.
Projects financed entirely from buyer instalments (off-plan sales funding construction) carry higher risk. If sales slow, construction can stall. This does not make such projects fraudulent, but it means your payment schedule terms and contractual delay penalties matter more.
Ask for the name of the financing bank (you do not need account details). You can verify the bank's existence and standing independently. If the developer claims bank financing but cannot name the bank, treat the claim as unverified.
What payment schedule terms protect me?
A safe payment structure links each instalment to a verified construction milestone - not to a calendar date. Examples of milestone-linked payments:
- Reservation fee: THB 50,000-200,000 (indicative) - refundable under defined conditions
- Foundation completion: 10-15% of purchase price
- Structural frame at floor X: a further percentage
- Building shell completion: a further percentage
- Transfer of title at Land Department: remaining balance (often 10-30%)
Red flag threshold: if the developer asks for more than 30-40% of the purchase price before the foundation stage is visibly complete and verified, the schedule front-loads risk onto you. Some reputable developers do ask for higher early-stage amounts, but those cases require stronger evidence of track record and bank financing.
The sale and purchase agreement (SPA) should specify a delay penalty - typically 0.01-0.025% of the unit price per day of delay beyond the agreed handover date (indicative, 2026 market practice). Without a written penalty clause, you have limited financial leverage if handover is late.
What can I verify online versus what requires a lawyer?
Some checks are genuinely accessible from abroad with internet access. Others require physical presence at Thai government offices, Thai-language reading ability, or professional authorization.

Risks and mistakes
Paying before title verification
The single most costly mistake is paying any amount - including a reservation fee - before your lawyer has confirmed the land title class and that the land is not mortgaged to a bank for more than the project's projected value. If the developer defaults and the land is under a bank mortgage, buyers can lose deposits entirely while the bank recovers the land. This has happened in documented Thai property cases.
Accepting renders as evidence of a building permit
A high-quality architectural render costs a developer a few thousand dollars. It is not evidence that planning permission exists. In Thailand, pre-permit sales are legal. That does not protect you if the permit is subsequently refused or the project design changes materially once permits are granted. Always ask for permit status in writing before committing.
Ignoring front-loaded payment schedules
If a developer asks for 50% or more before construction reaches an independently verifiable stage, you are effectively providing an unsecured loan to the developer. If the project fails, recovery through Thai courts is slow (cases can take three to five years), expensive, and rarely results in full recovery of funds.
Using only the developer's recommended lawyer
Some sales teams suggest a specific law firm for buyers. That firm may have an existing relationship with the developer. Your lawyer must be independently chosen and paid by you. Ask your lawyer directly whether they have any existing relationship with the developer before you engage them.
Not checking the foreign ownership quota
Under the Thai Condominium Act, a maximum of 49% of the total floor area in any condominium building can be foreign-owned freehold (the 'foreign quota'). If that quota is already 100% sold and the developer or agent has not disclosed this, you may be offered a structure such as a Thai company ownership, a long-term lease, or a nominee arrangement. Some of these structures carry legal risk for foreign buyers. Verify the available foreign quota in writing before signing.
Skipping the delay penalty clause
Many standard Thai developer contracts include a delay penalty that is far lower than the buyer's actual cost of a delayed handover - lost rental income, extended mortgage costs, storage fees. Negotiate a penalty rate in the SPA and ensure it applies per day from the contractually agreed handover date, not from an undefined 'reasonable delay' period.
Ignoring developer financial health signals
A developer who has recently reduced registered capital, changed directors multiple times in a short period, or has financial filings showing consistent losses relative to liabilities may face solvency risk. These signals do not confirm a developer will fail, but they are factors your lawyer should assess alongside the project-specific checks.
FAQ
Is there a government database where I can check Thai developer complaints?
There is no single government database specifically for developer complaints in Thailand as of 2026. The Consumer Protection Board and the Real Estate Information Center (REIC) publish some aggregate market data. Buyer complaints exist in court records (Courts of Justice portal), Land Department dispute logs, and Consumer Protection Board case files. Accessing these requires Thai language ability or a local lawyer. Online property forums provide anecdotal signals but are not legally conclusive.
Can a developer legally sell units before getting a building permit in Thailand?
Yes. Thai law does not prohibit pre-permit sales. Developers regularly sell off-plan before permits are issued. Your protection is contractual: require the SPA to specify that permit issuance is a condition for certain payment milestones, and include a refund clause if permits are refused within a defined period. A lawyer can draft or review these clauses.
What is the foreign quota in a Thai condominium and how do I verify it?
The Thai Condominium Act limits foreign freehold ownership to 49% of a building's total floor area. To verify how much of the quota remains available, ask the developer's juristic person office (the management entity for the building) for the current foreign quota certificate. Your lawyer can request this formally. If more than 49% of floor area is already foreign-owned, you cannot purchase freehold without waiting for an existing foreign owner to sell.
How do I verify that a developer's completed projects actually exist?
Ask the developer for the addresses and project names of at least two completed condominium buildings they have delivered. Then use Google Maps satellite view and Street View to confirm the buildings exist. For a higher level of verification, hire a local agent or lawyer to visit the site and photograph the building and its nameplate. Check whether the buildings have a registered juristic person (the legal management entity) - this confirms legal handover occurred.
What contractual delay penalty is standard in Thailand?
Per 2026 market practice, delay penalty clauses in Thai developer contracts typically specify 0.01% to 0.025% of the unit purchase price per day of delay beyond the agreed handover date. These are indicative figures. The exact rate is negotiable. If the developer's standard contract contains no penalty clause, ask your lawyer to add one. Without it, your only remedy for delay is a court claim, which is slow and costly.
Should I use the developer's recommended lawyer?
No. Your lawyer must be independent. A lawyer recommended by the developer may have an existing fee relationship or referral arrangement with the developer. Choose your own lawyer, pay them directly, and ask them to confirm in writing that they have no existing relationship with the developer. Independent legal advice for a Thai condominium purchase typically costs THB 20,000-50,000 (indicative, 2026 market estimates).
What does 'chanote' mean and why does it matter?
Chanote (formally Nor Sor 4 Jor) is the highest class of land title in Thailand. It indicates full ownership with GPS-surveyed boundaries recognized by the Land Department. Only a chanote title can support a legally registered condominium under the Thai Condominium Act. If the land behind a project carries a lower title class, the developer cannot legally register individual unit ownership in buyers' names until the title is upgraded - a process that adds time and uncertainty.
What happens to my deposit if a Thai developer goes bankrupt?
If a developer goes bankrupt, buyer deposits become unsecured creditor claims. Secured creditors (typically banks holding a mortgage over the land) are paid first. In practice, buyers often recover little or nothing through the bankruptcy process. This is why payment-schedule structure matters: the less money you have paid before construction reaches a verifiable stage, the less you stand to lose if the developer fails. There are no deposit insurance schemes or buyer-protection funds for foreign property buyers in Thailand as of 2026.
How do I find a developer's court litigation history?
The Courts of Justice of Thailand (www.coj.go.th) publishes some case information. Accessing it effectively requires Thai reading ability. Your lawyer can run a litigation search by company name and registration number at the relevant Civil Court. Ask your lawyer specifically to check for buyer claims (contract breach), creditor claims (unpaid debts), and any cases filed by the developer's own contractors - unpaid contractors are an early indicator of cash flow problems.
What is a sinking fund and should it concern me during developer vetting?
A sinking fund is a one-time payment collected at the point of title transfer, separate from monthly common area maintenance fees. It is held by the building's juristic person to cover major future repairs (roof, elevators, external structure). The amount is set by the developer - typically THB 300-600 per square metre (indicative, 2026 market estimates). When vetting a developer, check whether previous projects have adequate sinking funds: underfunded buildings from the same developer indicate a pattern of prioritizing sales volume over long-term building management, which affects resale value and your ongoing costs as an owner.
