Checking a Thai Developer's Track Record: 7 Verified Steps
By THAI.ESTATE Editorial Team15 min read
Vetting a Thai developer before you pay a deposit is one of the most effective ways to protect your money. The short answer: you can run meaningful background checks from abroad using public records, but the critical title and permit checks require a licensed Thai lawyer on the ground.
This guide gives you a step-by-step verification playbook for 2026, covering every check in order of priority. Each step tells you what to look for, where to find it, and what a red flag actually costs you if you ignore it.
Quick answer
- Start with completed projects. A developer with at least two delivered condominium or villa projects, both registered with the Land Department, is materially lower risk than a first-time developer.
- Verify the land title class. A chanote (full title deed, also called Nor Sor 4 Jor) is the only title class that supports clear foreign co-ownership of a condominium unit. Weaker titles - Nor Sor 3 Gor, Sor Kor 1 - carry legal risk.
- Confirm the building permit exists before you pay. Under the Building Control Act, a valid construction permit (or Aw Por 3) must be issued before any structural work begins. No permit at the time of sale is a hard red flag.
- Check the EIA. Projects above 80 units or 4,000 square metres in sensitive zones legally require an Environmental Impact Assessment approval before construction starts.
- Understand how construction is financed. A developer financing the build entirely from buyer instalments - with no bank construction loan behind the project - puts your deposits at direct risk if sales slow down.
- Request milestone-linked payment schedules. In Thailand there are no escrow accounts protecting buyer funds. Your protection is a contract where payments track verified construction milestones, backed by a penalty clause for delays.
- Run a litigation check. A competent Thai lawyer can search the Court of Justice database for active or past cases against the developer company within one to two business days.
Options and scenarios
How do I check a Thai developer's completed-project track record?
The fastest first check is straightforward: ask the developer or their sales team for a list of completed projects by name, location, and year of transfer. Then verify independently.
The Land Department maintains a Central Registration database (accessible at the provincial Land Office level). A Thai lawyer can pull registration records for any condominium juristic person - the legal body formed when a condominium building is registered. If a building appears as a registered juristic person, the project was completed and transferred to buyers. No juristic person registration means the project was never completed or never registered.
For completed projects you can find online, look for:
- Google Street View or satellite imagery to confirm the building physically exists.
- Juristic person committee meeting minutes, which some condominiums publish on community boards or management websites. These confirm ongoing operations.
- Delivery date versus advertised date. Ask buyers in online forums (there are active English-language Thailand property communities) how long the developer ran over schedule. A delay of six to twelve months is common in the market. A delay beyond eighteen months, or an unfinished project from a prior cycle, is a serious signal.
A developer with fewer than two completed projects, or whose only completed project was a small serviced apartment in a different market segment, deserves extra scrutiny on financing and permit status before you proceed.
How do I verify the land title behind a Thai project?
The chanote (Nor Sor 4 Jor) is Thailand's highest-grade land title. It is GPS-surveyed, free of boundary disputes, and is the title class required for condominium registration under the Condominium Act.
Weaker title classes you may encounter:
- Nor Sor 3 Gor - surveyed but boundaries may be contested; legal to transact but riskier
- Sor Kor 1 - a possession certificate only, not a full title deed; legally cannot underpin a condominium
- Por Bor Tor 5 - agricultural use certificate; frequent in peripheral villa projects; cannot be converted to freehold without a formal Land Department process
You cannot verify the title class from abroad with certainty. A Thai lawyer must physically visit the Land Office in the province where the project sits, request the title document, and confirm it is a chanote in the developer's name (or in the name of a company the developer demonstrably controls). This check typically takes one to two business days and costs 2,000 to 5,000 THB (indicative figures, as of 2026) as part of a basic due diligence report.
If the title is still held in the name of a third-party landowner with only a lease or option agreement in place, that is an additional risk layer: your purchase depends on that landowner relationship holding throughout the build.
How do I check if an EIA and building permit are in place?
The Environmental Impact Assessment (EIA) is a government approval document issued by the Office of Natural Resources and Environmental Policy and Planning (ONEP). For condominiums, the legal thresholds that trigger a mandatory EIA include projects over 80 units or over 4,000 square metres of total floor area in certain zones. Coastal and resort-zone projects face stricter thresholds.
Ask the developer to share the EIA approval reference number. A legitimate EIA approval is a public record. Your lawyer can verify the reference number with ONEP directly.
The building permit (Aw Por 3) is issued by the local municipality or administrative authority (in major tourist areas, often the City Hall or Sub-district Administrative Organization). It must be posted at the construction site under Thai law. If you are visiting the site, photograph it. If you are buying from abroad, your lawyer can request a copy and verify it against the issuing authority's records.
Buying before a permit is issued is the single most common financial loss scenario for foreign buyers. Developers sometimes sell units at attractive pre-permit prices, citing an expected permit date. If the permit is refused or delayed by twelve to twenty-four months, the project stalls while your deposit is held with no contractual release mechanism. The cost: your full deposit is at risk, legal recovery is slow and expensive, and the opportunity cost of capital locked for two-plus years is real.
How do I check how a developer is financing construction?
Construction financing structure is the least-discussed risk by sales teams and the most important factor in project completion probability.
There are three common models:
1. Bank-financed construction. A Thai commercial bank has issued a construction loan to the developer, secured against the project land and typically conditional on a minimum pre-sale rate (often 30 to 50 percent of units). This model means the bank has independently assessed the developer's creditworthiness and project viability. It is the lowest completion risk for buyers.
2. Self-financed by the developer. The developer uses retained earnings or corporate capital. This is acceptable if the developer is large and financially transparent, but you cannot verify this from abroad. Ask for audited accounts.
3. Buyer-instalment-financed. The developer is building with your deposits and those of other buyers. If sales slow, the developer may not have funds to continue. This model is not inherently illegal, but it is the highest completion risk. In this scenario, a robust milestone-linked payment schedule is your only protection: you pay each tranche only when a defined construction stage is independently verified.
How to check: ask the developer directly whether a bank construction facility is in place, and request the bank's name and the loan facility letter (developers sometimes share a redacted version). If they refuse to confirm any bank involvement, treat the project as buyer-instalment-financed.
How do I run a litigation check on a Thai developer?
Thailand's Court of Justice maintains case records. A Thai lawyer can search by company name for active civil or criminal cases in provincial and central courts. This is a standard step in a professional due diligence report.
What you are looking for:
- Civil cases brought by buyers for non-delivery, defective construction, or contract fraud - these are the highest-signal red flags
- Labour cases suggesting unpaid contractor or worker claims (often a sign of cash flow problems)
- Revenue Department assessments or tax disputes that have reached court level
- Criminal complaints related to the developer's directors
A clean litigation record does not guarantee a safe developer, but active buyer lawsuits are an immediate stop sign. A single active lawsuit from a buyer is not necessarily disqualifying; a pattern of five or more is.
This check costs approximately 3,000 to 8,000 THB (indicative, 2026) as part of a legal due diligence package. It can be completed remotely by the lawyer without a site visit.
What can I verify myself from abroad versus what needs a lawyer on the ground?
This is a practical question with a clear boundary.
You can do from abroad:
- Search the developer's company registration on the Department of Business Development (DBD) website (dbd.go.th). You can confirm the company exists, its registration date, and its registered directors - all public records.
- Search the developer's name in English-language property and expat forums for buyer experiences with past projects.
- Request and review the sales contract in English and Thai, noting payment schedule structure, delay penalty clauses, and defect warranty terms.
- Ask for the EIA approval reference number and cross-check with ONEP's public announcements.
- Review the developer's own marketing materials critically: renders sold without a visible permit date, aggressive early-stage payment demands, or claims of government-backed guarantees are all warning signs.
You need a Thai lawyer for:
- Physical verification of the land title at the provincial Land Office
- Confirmation that the building permit number is genuine and current
- Litigation search in the Court of Justice database
- Review of the Thai-language contract version (which governs in any dispute)
- Structural review of the payment schedule against construction milestones
- Verification of the juristic person registration for any claimed completed projects
Budget for professional legal due diligence: 15,000 to 40,000 THB for a standard report (indicative, 2026, varying by scope and firm). This covers the checks above and a written report. For a purchase of 3 to 20 million THB, this cost is proportionate.
Comparison table
| Check | Can you do it from abroad | Cost (indicative, 2026) | Risk if skipped |
|---|---|---|---|
| Company registration (DBD) | Yes, online | Free | Low - easy to run |
| Completed project track record | Partially (forums, satellite) | Free | Medium - hard to fully verify remotely |
| Land title class (chanote) | No - lawyer required | 2,000-5,000 THB | High - wrong title voids your purchase rights |
| Building permit (Aw Por 3) | Partially (ask developer) | 3,000-6,000 THB with verification | Very high - deposit lost if permit refused |
| EIA approval | Partially (ONEP records) | Included in legal report | High in coastal/resort zones |
| Construction financing structure | Partially (ask developer) | Free to ask | High - unfinanced builds stall |
| Litigation search (court records) | No - lawyer required | 3,000-8,000 THB | High - reveals buyer fraud pattern |
| Thai contract review | No - bilingual lawyer required | Included in legal report | Very high - Thai version governs disputes |
Risks and mistakes
Paying a deposit before the land title is verified
This is the most costly single mistake. If the project land carries a weaker title class - or if the land title is in the name of a third party with only an informal arrangement with the developer - your purchase agreement may be unenforceable. You could lose your entire deposit with no viable legal remedy. The fix: instruct your lawyer to verify the chanote before you pay anything, including a reservation fee.
Treating a reservation fee as low-risk
Developers sometimes present a reservation fee (typically 50,000 to 200,000 THB for a mid-range unit) as a casual step. In practice, reservation fee terms vary widely. Some contracts allow full recovery if due diligence fails; many do not. Read the reservation agreement before you pay, or have your lawyer read it. Paying without reading the refund conditions is a common and avoidable loss.
Accepting front-loaded payment schedules
A payment schedule that requires 30 to 50 percent of the purchase price before the foundations are completed is structurally weighted in the developer's favour. Healthy milestone structures spread payments: reservation, contract signing, foundation complete, structure complete, fit-out complete, handover. If a developer demands 50 percent at contract signing with no construction started, that is an aggressive and high-risk schedule. The cost when the project stalls: the portion paid is at risk and recovery through Thai courts takes two to five years.
Relying on marketing renders and floor plans as legal commitments
Rendered images and floor plans in brochures are marketing materials, not legal commitments. Changes to unit size (up to 5 percent in either direction is sometimes permitted under standard contracts), common area specifications, view lines, and landscaping are all possible between render and delivery. The only legally binding description of your unit is in the signed Thai-language contract. If the English translation conflicts with the Thai version, the Thai version governs.
Skipping the litigation check to save cost
A litigation check costs a small fraction of your purchase price and takes one to two business days. Skipping it to save 3,000 to 8,000 THB on a 5,000,000 THB purchase is a poor trade. A developer with active civil cases brought by buyers from a prior project is a pattern you need to know about before, not after, you sign.
Assuming developer reputation is verifiable through marketing alone
Some developers operate multiple registered companies across projects. A company with a clean record may be under different ownership or directorship than a problem project from three years ago, even if the brand name is similar. Check the DBD registration for the specific company selling the current project. Confirm that the same directors appear, and if the company is newly formed (registered within the past twelve months), treat that as a signal requiring deeper scrutiny of financing.
FAQ
How do I check a Thai developer's track record online?
Start with the Department of Business Development website (dbd.go.th) to confirm the developer's company registration, registration date, and listed directors. Then search the developer's project names in English-language property forums for buyer feedback. For confirmed completed projects, a Thai lawyer can check juristic person registration with the Land Department.
What is a chanote and why does it matter for my purchase?
A chanote (formally Nor Sor 4 Jor) is Thailand's highest-grade land title deed. It is GPS-surveyed and legally unambiguous. Under the Condominium Act, a condominium can only be registered on land with a chanote or equivalent high-grade title. If the project land does not have a chanote, you cannot receive a legally registered condominium unit title in your name.
What is the building permit and when should it be issued?
The building permit (Aw Por 3) is issued by the local municipal authority and legally must be in place before construction begins. You should not pay a deposit on a project where the permit has not yet been issued. If a developer is selling pre-permit, your deposit is exposed to the full risk of permit refusal or indefinite delay.
Is there any protection for my payments in a Thai off-plan purchase?
There are no escrow accounts protecting buyer funds in Thailand in the traditional sense. Your protection comes from three sources: a payment schedule tied to verifiable construction milestones (not calendar dates), a contractual penalty clause for delays (typically 0.01 to 0.1 percent of the purchase price per day of delay, as market convention - confirm in your specific contract), and the developer's verified delivery record on past projects.
How do I know if a developer is financing construction from buyer deposits?
Ask directly: does the project have a bank construction loan, and if so, which bank? A developer with a legitimate bank facility will usually confirm this, as it is a selling point. If the developer cannot or will not name a bank lender, treat the project as buyer-instalment-financed and apply stricter scrutiny to the payment schedule.
How long does legal due diligence take for a Thai property purchase?
A standard due diligence report covering company registration, land title, permit status, EIA confirmation, and a litigation search typically takes five to ten business days from instruction. Rush reports in two to three days are possible at higher cost. Do not let a developer's sales deadline pressure you into skipping or shortening this step.
What red flags should make me walk away immediately?
Four hard stop signs: (1) no building permit issued at the time of sale; (2) land title is not a chanote or equivalent; (3) active civil lawsuits from buyers of a prior project; (4) a payment schedule requiring more than 30 percent of the purchase price before the structure is above ground, with no bank construction loan in place.
Can I use the Thai court system to recover a lost deposit?
Yes, but it is slow and expensive. Civil litigation in Thailand typically takes two to five years to reach a judgment, and enforcement of a judgment against a company that has dissolved or restructured adds further complexity. Prevention - verifying the developer before you pay - is the only cost-effective protection.
What is a juristic person and how does it confirm project completion?
Under the Condominium Act, once a condominium building is completed and units are transferred to buyers, the co-owners are required to form a condominium juristic person - a legal body that manages common areas and finances. Registration of this juristic person with the Land Department is public record and confirms that the project was completed and handed over. If a developer claims a building is completed but no juristic person is registered, investigate further.
How much should I budget for legal due diligence in Thailand?
For a residential purchase (condominium or villa), budget 15,000 to 40,000 THB for a professional due diligence report (indicative, 2026). This covers company and title checks, permit and EIA verification, a litigation search, and a Thai-language contract review with an English summary. On a purchase of 3 to 20 million THB, this is a proportionate and necessary cost.
