Vetting a Condo Developer in Thailand: 7 Checks Before You Pay
By THAI.ESTATE Editorial Team14 min read
Foreign buyers lose money in Thai pre-sale condominiums almost always for the same reason: they paid before verifying. Vetting a condo developer in Thailand means running seven specific checks against public records and legal documents before you transfer a single baht. This guide tells you exactly what to check, where to find it, and what each failure costs.
The checks divide into two categories: what you can do online from abroad, and what requires a licensed Thai lawyer on the ground. Both matter. Skipping the lawyer-side checks is the most common and most expensive mistake foreign buyers make.
Quick answer
- Check the land title first. The project land must carry a chanote (Nor Sor 4 Jor) title - the highest class of Thai freehold title. Lower classes (Nor Sor 3, Sor Kor 1) carry boundary and ownership risk.
- Verify the building permit and EIA before paying any reservation fee. A developer selling from renders without a permit is selling you a legal uncertainty, not a condo.
- Inspect at least two completed projects by the same developer. Look for actual delivery dates versus promised dates. Delays of 12-24 months are common in the market; delays beyond 36 months are a red flag.
- Ask how the project is financed. Bank construction financing tied to drawdown milestones protects you. Buyer instalment money used as the primary construction fund puts you at direct risk if sales slow.
- Read the payment schedule against construction milestones. A legitimate schedule links each payment to a verifiable stage: foundation, structure, shell completion, fit-out, handover. Front-loaded schedules (paying 50%+ before the structure is up) shift all risk to you.
- Check litigation history via the Thai Courts public portal (available in Thai; a lawyer can query it in minutes).
- Confirm the developer entity in the Department of Business Development (DBD) database. Registered capital, director names and annual filings are all public. A developer with low registered capital and no audited accounts is a structural warning.
Options and scenarios
How do I check a Thai developer's track record from abroad?
Start with what is publicly searchable in English or verifiable with minimal Thai reading.
Step 1: DBD company search. Go to the Department of Business Development portal (dbdregistry.dbd.go.th). Search the exact company name as shown on the sales contract. Confirm the company is active, note its registered capital (indicative minimum for a credible mid-size developer is 50-100 million THB, per market observation), and download the most recent annual balance sheet if available. A developer registered six months before the project launch with minimal capital deserves deeper scrutiny.
Step 2: Completed project list. Ask the developer's sales team for a list of completed projects with addresses. Then verify independently. Search Thai property listing databases for those building names. If residents live there, the building is real. If the sales team cannot name two completed buildings, that is a red flag.
Step 3: Condominium Act registration. Under the Thai Condominium Act (most recently amended in 2022), a completed condominium building must be registered with the Land Department before individual unit titles (chanote) can be issued to buyers. Ask the developer: 'How many of your completed projects have issued individual chanote to all buyers?' Stalled chanote issuance after handover is a known problem in the Thai market.
Step 4: Online reputation, with caution. Expat forums and review threads can surface serious complaints (incomplete common areas, delayed chanote, unpaid contractor disputes). Treat these as leads for your lawyer to verify, not as conclusions.
How do I verify the land title behind the project?
This check cannot be done reliably from abroad. You need a Thai lawyer to visit the local Land Department office and pull the official title extract for the plot.
The chanote (Nor Sor 4 Jor) is Thailand's strongest land title. It carries GPS-surveyed boundaries and full transferability. Lower titles carry risks: Nor Sor 3 Gor allows transfer but boundaries are less precise; Sor Kor 1 is an occupancy acknowledgement, not ownership, and cannot legally underpin a condominium registration.
Your lawyer must also check: who holds the chanote. It should be the developer entity named in your contract, or held in a verifiable escrow-type arrangement pending project completion. If the land is held by a different company, a major shareholder personally, or is mortgaged to a bank, all of those facts change your risk profile. A bank mortgage on the project land is not automatically disqualifying - developers routinely mortgage land to secure construction loans - but the terms must be reviewed. If the developer defaults on the construction loan, the bank's claim on the land ranks ahead of your deposit.
How do I check EIA approval and building permits?
Environmental Impact Assessment (EIA): Projects above certain size thresholds (generally condominiums over 80 units or 4,000 square metres of usable space, per Office of Natural Resources and Environmental Policy and Planning guidelines as of 2025) require an EIA approval before construction. The approval is issued by a government agency and is a matter of public record. Your lawyer can obtain confirmation. A developer who tells you the EIA 'is in process' while taking your reservation fee is asking you to fund their approval risk.
Building permit (Bai Anuyart Kor Sang): This is issued by the local municipality (Tessaban or Or Bor Tor, depending on location) or by the provincial government. It is project-specific and plot-specific. Without a permit, construction is illegal and the building cannot be registered under the Condominium Act. Ask for the permit number and issue date. Your lawyer can verify it at the issuing office within one working day.
The combination of no EIA plus no permit is the single highest-cost red flag. Buyers who paid 30-50% of unit price at pre-permit stage in failed Thai projects have spent years and significant legal fees recovering deposits - often with partial recovery at best, per documented dispute patterns in the Thai market.
How do I assess construction financing risk?
There are two main models in Thailand, and they carry very different risk profiles for buyers.
Model 1: Bank-financed construction. The developer secures a project construction loan from a Thai commercial bank before launch. The bank conducts its own due diligence on the land title, permits and developer financials. Drawdowns are tied to verified construction stages. This model means an independent institution has already stress-tested the project. It does not guarantee completion, but it substantially reduces buyer risk.
Model 2: Buyer-instalment-financed construction. The developer uses buyer reservation fees, down payments and stage payments as the primary source of construction capital. This model is common in smaller and mid-market Thai developers, and it is legal. However, it means that if sales slow - as happened broadly in the Thai condo market in 2023-2024 per market observations - the construction budget shrinks. Your payments fund the building you hope to receive.
Ask the developer directly: 'Does this project have a bank construction facility?' Request the name of the financing bank (you do not need the loan amount). If the developer cannot confirm bank financing, price that risk into your decision. Require stronger contractual delay penalties (see below).
What payment schedule terms protect a foreign buyer?
A safe payment schedule for a Thai off-plan condo typically looks like this (indicative, as of 2026 market practice):
- Reservation fee: 1-5% of unit price, refundable if due diligence fails
- Contract signing (within 30 days): 10-15%
- Foundation complete: 10%
- Structure complete: 10-15%
- Shell and facade complete: 10%
- Fit-out and handover: remaining balance (often 50-60%)
Red flag threshold: any schedule requiring more than 30% of the total price before the structure is visibly above ground. A developer asking for 50% at contract signing is transferring maximum financial risk to you at the moment your legal protection is weakest.
Your contract must include a delay penalty clause: typically 0.01-0.05% of the unit price per day of developer delay beyond the agreed handover date, per standard Thai market terms. Without this clause, your remedy for a two-year delay is litigation, not compensation.
What can a foreign buyer realistically verify online versus on the ground?
Some checks are accessible remotely; most of the meaningful ones are not. The distinction matters because many foreign buyers rely entirely on the developer's sales materials and a quick internet search. That is not enough.
Online from abroad (English-accessible or with basic tools):
- DBD company registration and capital (dbdregistry.dbd.go.th, partially in English)
- Developer website and completed project portfolio cross-referenced with satellite maps
- Property listing databases for evidence of residents in claimed completed buildings
- General forum and review research (treat as leads only)
Requires a Thai lawyer or qualified local representative:
- Land title class and ownership verification at the Land Department
- Building permit number and validity check at the municipal office
- EIA approval status
- Mortgage or encumbrance on the project land
- Court litigation check (Civil Court and Central Bankruptcy Court databases)
- Contract review: delay penalties, defect liability, force majeure scope, chanote issuance timeline
- Condominium juristic person (the building's management entity under the Condominium Act) governance documents for resale purchases
A qualified Thai property lawyer charges approximately 15,000-30,000 THB for a standard pre-purchase due diligence report on a condo purchase, per market estimates as of 2026. Against a purchase price of 3-10 million THB, this is a minor cost with significant protective value.

Risks and mistakes
Paying a reservation fee before due diligence. In Thailand, a reservation fee (typically 50,000-200,000 THB) is often treated as non-refundable by the developer the moment you sign the reservation form. Get your key checks done - at minimum, confirm the permit exists - before you pay anything. Negotiate a due diligence period of 14-30 days before the reservation becomes non-refundable.
Accepting a photocopy of the chanote. Developers routinely provide copies. A copy does not confirm current ownership or whether the land is mortgaged. Only a fresh title extract from the Land Department, pulled by your lawyer, confirms the current state of the title.
Confusing 'EIA submitted' with 'EIA approved'. These are two different things. An EIA application can sit in review for 12-24 months. If you pay before approval, you are funding the developer's wait.
Ignoring the juristic person documents. For a resale condo, the juristic person (the legal entity that manages the building under the Condominium Act) holds the sinking fund (a mandatory reserve fund collected from all owners at the time of initial sale, used for major building repairs) and manages common area fees. A building with a deficit in its sinking fund, or with litigation between owners and the juristic person, is a liability you inherit as the new buyer. Ask for the most recent audited accounts of the juristic person.
Relying on the developer's own lawyer. Some developers offer buyers free legal support. That lawyer acts for the developer. You need a lawyer who acts only for you, with no referral relationship to the developer or sales agent.
Underestimating force majeure clauses. Thai standard contracts often include broad force majeure language that can excuse completion delays of 12-24 months without triggering delay penalties. Your lawyer must review this clause specifically and negotiate limits where possible.
Not checking the foreign buyer quota. The Condominium Act limits foreign freehold ownership to 49% of the total unit area in a building. If a building is at or near quota, your purchase may need to proceed as a Thai-name leasehold structure instead, which carries different legal risks. Confirm the current foreign quota status before you sign.
FAQ
What is the single most important check before buying a pre-sale condo in Thailand?
Verify that the building permit has been issued before you pay anything beyond a refundable reservation. Without a permit, the building cannot be legally constructed or registered, and your deposit is unsecured by any physical asset.
How do I check if a Thai developer has a history of delays?
Ask the developer for a full list of completed projects with their promised and actual handover dates. Then verify those dates independently: check property listing histories, contact building juristic persons, and ask your lawyer to review any public complaints or court filings linked to those projects.
What does chanote mean and why does it matter?
A chanote (Nor Sor 4 Jor) is Thailand's highest class of land title. It carries GPS-surveyed boundaries and full legal transferability. Projects built on lower-class titles face boundary disputes and cannot issue individual unit titles to condo buyers under the Condominium Act. Always insist the project land carries a chanote before proceeding.
Can I lose my deposit if the developer goes bankrupt?
Yes. If the developer becomes insolvent before the project completes, your instalment payments rank as unsecured creditor claims in Thai bankruptcy proceedings. Recovery depends on the bankruptcy estate's assets and takes years. The primary protection is buying from financially stable developers with bank-financed construction, and keeping your instalment payments aligned with verified construction milestones.
What is a sinking fund in a Thai condo?
A sinking fund is a one-time reserve payment collected from all unit buyers at the time of first ownership transfer, typically 400-700 THB per square metre (indicative, 2026 market rates). It funds major future repairs: roof replacement, elevator overhaul, facade work. A building with an undersized or depleted sinking fund will either defer maintenance or levy special assessments on owners.
How much does a Thai property lawyer cost for due diligence?
For a standard condo purchase due diligence report covering title, permits, contract review and litigation check, expect approximately 15,000-30,000 THB as of 2026, per market estimates. For high-value purchases (above 10 million THB), some lawyers charge a percentage-based fee. Always agree the scope and fee in writing before engaging.
What is the foreign buyer quota rule for Thai condominiums?
Under the Thai Condominium Act, foreign nationals (non-Thai) can collectively hold freehold ownership of no more than 49% of the total registered unit area in any single condominium building. If that quota is full, you can only buy on a leasehold basis (typically 30 years plus options), which is a materially different legal position.
What delay penalty should I insist on in a Thai condo contract?
The market standard for delay penalties in Thai condo contracts is 0.01% of the unit price per day of developer delay beyond the agreed handover date. Negotiate for 0.05% per day if you can. Equally important: confirm there is a longstop date beyond which you can cancel and recover all payments if the developer has not delivered.
Is it safe to buy from a developer that has no completed projects yet?
It carries higher risk. A developer with no delivered track record means you cannot verify actual build quality, delay history, or chanote issuance practice. If you proceed, require bank-confirmed construction financing, keep your milestone payments strictly linked to verified construction progress, and retain independent legal representation throughout the construction period.
What is the juristic person and why should I check it before buying a resale condo?
The juristic person is the legal management entity established under the Thai Condominium Act to administer a registered condo building. It collects monthly common area fees and manages the sinking fund. Before buying a resale unit, ask for the juristic person's most recent audited financial statements. Confirm there are no major unpaid contractor debts, fee arrears from previous owners, or active litigation against the building.
