How to Assess Off-Plan Developer Risk in Thailand: A Practical Guide (2026)

Thailand has no mandatory escrow law for real estate. When you pay a deposit or installment on an off-plan condo in Phuket, that money goes directly to the developer’s account — not to a protected escrow fund. If the developer defaults, your recovery options are limited to civil litigation in Thai courts, which is slow and uncertain. This doesn’t mean off-plan buying is a bad idea — Phuket’s off-plan market has produced excellent returns and most developers deliver — but it means your due diligence is your only real protection.

Off-Plan Risk Assessment: Quick Reference

Risk Factor	Low Risk	Medium Risk	High Risk
Developer track record	3+ completed projects	1–2 completed projects	First project
Company structure	SET-listed / publicly traded	Private, established	Recently formed company
Construction status	Foundation laid, EIA approved	Pre-construction, permits pending	Pre-launch, no permits
Land title	Chanote (full title deed)	Nor Sor 3 Gor	No clear title info
Construction permit	Issued	Applied for	Not applied
Sales rate	60–80%+ sold	30–60% sold	Under 30% sold
Bank financing	Construction loan from major Thai bank	Partial bank financing	Entirely self-funded
Payment structure	Milestone-linked installments	Time-based installments	Large upfront payments
Independent lawyer review	Completed before signing	Planned	Not considered

Why Off-Plan Exists and Why Buyers Accept the Risk

Off-plan property — buying before construction completes — is the dominant sales model in Phuket for new-build condos. Developers prefer it because pre-sales cash flow funds construction without pure bank debt. Buyers accept it because:

• Price discount: Off-plan units typically sell at 15–30% below the projected completed-unit market price
• Payment spread: Milestone-based installments (30% on signing, 20% at foundation, 20% at structure, 30% on completion) spread cash outflow over 18–36 months
• Capital appreciation: In a rising market, buyers who buy off-plan have locked in a lower price; by completion the value has often risen

The risk is real: Thai law does not protect buyers with mandatory escrow. But the market’s track record is substantially better than its reputation in some circles. The vast majority of projects by established developers deliver on time or close to schedule. The risk concentrates heavily in small, private developers with thin capital and ambitious projections.

Step 1: Verify the Developer’s Legal Entity

Before paying anything, establish that you’re dealing with a legitimate registered Thai company.

Department of Business Development (DBD) check: Every Thai company is registered with the DBD (กรมพัฒนาธุรกิจการค้า). You can check company registration at dbdregistry.dbd.go.th or have your lawyer pull the company’s affidavit (หนังสือรับรองบริษัท). This document shows:

• Company registration date and status (active/dissolved)
• Registered capital (important — thin capital is a warning sign)
• Directors’ names and nationalities
• Registered address

A legitimate developer will have a company registered for several years with substantial paid-up capital (typically ฿10M–100M+ for serious projects). A company registered 3 months before the project launch with ฿1M registered capital is a concern.

Land title verification: Request the title deed number and have your lawyer check it at the local Land Department office. You’re looking for:

• Chanote (โฉนดที่ดิน): Full title deed — the gold standard; suitable for development and transfer
• Nor Sor 3 Gor (นส.3ก): Can be converted to Chanote; acceptable but requires verification
• Avoid: Land with only possession documents or disputed status

Verify that the land is registered under the developer company’s name, not a third party, and has no encumbrances (mortgages, liens, court orders). A heavy construction mortgage on the land is normal; check whether the developer plans to have it released before unit transfers.

Step 2: Confirm Construction Permits and EIA

Construction Permit

Every building project in Thailand requires a construction permit (ใบอนุญาตก่อสร้าง) issued by the local authority (municipality or district office). For a project to have a valid permit:

• Architectural plans must have been approved
• The project must comply with local zoning regulations
• Building setbacks, height limits, and floor area ratios must be met

Ask the developer directly: “Can you show me the construction permit?” A developer who can’t produce this document for a project actively selling is a serious red flag. Many developers in Phuket begin sales before receiving their permit — this is common and not necessarily dishonest, but it is a risk you’re taking.

Environmental Impact Assessment (EIA)

Projects of significant scale in Thailand require an Environmental Impact Assessment approved by the Office of Natural Resources and Environmental Policy and Planning (ONEP). In Phuket, projects near the coast or in ecologically sensitive areas face stricter EIA requirements.

An approved EIA means:

• The project has passed environmental review
• It is less likely to face injunctions or forced modifications
• The developer has invested substantially in compliance

A missing EIA approval for a large coastal project is a red flag. Ask: “What is the EIA status of this project?”

Step 3: Evaluate the Developer’s Track Record

Track record is the single most predictive factor for developer reliability. Ask for a list of completed projects and then verify independently:

Verification methods:

• Visit completed projects physically (or ask someone you trust in Phuket to do so)
• Check Google Maps, TripAdvisor, or Airbnb listings for the completed project — do units appear listed and occupied?
• Ask the developer’s sales team for contact information of existing unit owners (they may decline, but established developers sometimes provide this)
• Search Thai online property communities (Facebook: “Phuket Property Investors,” “Phuket Real Estate”) for mentions of the developer

Minimum track record threshold for confidence: At least 2–3 completed and delivered projects with units transferred to buyers. Completion certificates (Condominium Registration Certificate) have been issued. Juristic persons established.

Listed company advantage: Developers listed on Thailand’s Stock Exchange (SET) — including Sansiri (SIRI), Origin Property (ORI), Pruksa Holding (PSH), and others — are subject to SEC disclosure requirements, audited financials, and shareholder accountability. They are materially less likely to default or abandon projects. Many Phuket off-plan projects are by smaller regional developers, not SET-listed companies, but a SET-listed developer is a meaningful de-risking factor.

Step 4: Review the Payment Structure

How you pay reveals and determines your risk exposure.

Milestone-Linked Payments (Best)

The safest payment structure ties installments to verified construction milestones:

• Reservation fee: ฿50,000–200,000 (refundable in due diligence period of 7–14 days)
• SPA signing (30%): After receiving and reviewing the SPA
• Foundation completion (10–20%): Verified with construction photos/site visit
• Structure completion (10–20%): Column frames visible
• Shell completion (10–20%): Walls, roof
• Final completion/handover (30%): Unit ready, punch list done

If any milestone is not met, you stop paying. This is leverage.

Time-Based Payments (Common but Riskier)

Many Thai developers offer time-based installment plans: X% now, X% in 6 months, X% in 12 months — regardless of construction progress. This is convenient but removes your payment leverage. You’re funding the developer based on a calendar, not actual construction achievement.

Lump Sum or Large Upfront Payment (Avoid)

Avoid any structure requiring 70%+ of the purchase price before construction reaches an advanced stage. Some developers offer “early bird” discounts in exchange for large upfront payments — the discount doesn’t justify the risk.

Negotiate delay penalties: A well-structured SPA includes a penalty clause for construction delays, typically 0.01% of the purchase price per day of delay beyond the contracted handover date. On a ฿5,000,000 unit, this is ฿500/day — not life-changing but a meaningful signal of the developer’s accountability.

Step 5: Hire an Independent Thai Lawyer

This is the single most important action you can take, and it should happen before signing any document beyond a refundable reservation form.

What a property lawyer does in off-plan due diligence (฿15,000–30,000 for a full review):

• DBD company verification
• Title deed search at Land Department
• Encumbrance check (mortgages, court orders on the land)
• EIA and construction permit status verification
• SPA review: spotting unfavorable clauses, incomplete specifications, weak penalty provisions
• Condominium Act compliance check (foreign quota, unit registration)
• Advise on power of attorney, FET form requirements, and transfer process

Critical: Do not use the developer’s recommended lawyer or a lawyer who has represented the developer in other transactions. Get an independent lawyer. The cost is trivial relative to your investment. MORE Group partners with independent English-speaking Thai lawyers who can conduct this review.

Step 6: Identify Warning Signs During Construction

Off-plan purchases require ongoing monitoring, not just pre-purchase due diligence.

Warning signs that a project may be in trouble:

• Construction stops for 30+ days without explanation. Ask the developer’s sales team directly and request a written explanation.
• Management or ownership change announced mid-construction. New management may not honor previous commitments.
• No response to status inquiries. Established developers have client relations teams that respond within 24–48 hours.
• Resale listings appear well below initial purchase price. If investors are cutting losses and selling at discounts, it signals something may be wrong.
• No construction activity visible on site visits or provided photos. Require monthly construction updates in your SPA.

What to do if warning signs appear:

1. Immediately consult your Thai lawyer
2. Stop further payments until you receive a satisfactory explanation in writing
3. Organize with other buyers — collective action has more leverage than individual complaints
4. Review your SPA: what remedies does it provide for non-delivery?

Step 7: Understand the FET Form Requirement

When transferring money from abroad to purchase a Thai property, the receiving Thai bank issues a Foreign Exchange Transaction Form (FET form, formerly FETF). For freehold condo ownership by a foreigner, the FET form is mandatory proof that the purchase price came from abroad.

Practical implications:

• Transfer funds in a single or clearly trackable set of international SWIFT transfers to the developer’s account (or your Thai account, then to developer)
• Keep every FET form original — you will need them at title transfer and again when you eventually sell
• If paying in installments, each installment transfer should generate its own FET documentation
• Transfers must clearly reference the unit number and project name

Buying off-plan in installments over 24 months means you’ll have multiple FET forms — keep them all in a safe location, ideally scanned and stored digitally as backup.

Pros and Cons: Buying Off-Plan in Phuket

Pros

• 15–30% price discount vs completed-unit market value
• Payment spread over 18–36 months (cash flow friendly)
• Capital appreciation potential during construction period
• First-choice unit selection (best floors, views, orientation)
• Modern specifications — newer buildings have better layouts, energy efficiency

Cons

• No mandatory escrow protection in Thailand
• Developer default risk (concentrated in smaller, private developers)
• Delays are common (6–12 months typical; rare cases 2+ years)
• Specification changes possible (materials, finishes, layout modifications)
• FET documentation must be managed across multiple transfers
• You can’t see the finished product before committing
• Opportunity cost: capital is tied up during construction

Frequently Asked Questions

Is buying off-plan in Thailand safe? +

Buying off-plan in Thailand carries real risks, primarily because there is no mandatory escrow law protecting buyer deposits. However, the majority of established developers with completed project track records deliver as promised. The risk concentrates in first-time developers, projects without construction permits at time of sale, and deals with large upfront payment requirements. Mitigate risk through independent legal due diligence (฿15,000–30,000), milestone-linked payment structures, and limiting purchases to developers with at least 2–3 previously completed projects.

What happens if an off-plan developer in Thailand defaults? +

If a Thai developer defaults on a project, buyers' primary legal recourse is civil litigation in Thai courts — a slow process that can take 2–5 years and may result in partial recovery at best. There is no government guarantee or escrow fund. In practice, defaults by major developers are rare; more common is significant delay (6–24 months beyond promised handover). If a developer stops construction, organize with other buyers, engage a Thai lawyer immediately, and document all communications. Some cases have resulted in buyers successfully receiving refunds or alternative unit arrangements through collective negotiation.

How do I verify an off-plan developer's credentials in Thailand? +

Check the company registration at Thailand's Department of Business Development (DBD) website — search by company name to see registration date, paid-up capital, and director information. Have a Thai lawyer search the land title at the local Land Department to confirm the developer owns the land free of problematic encumbrances. Ask for proof of the construction permit and EIA approval. Search for independent reviews from owners in the developer's completed projects on Facebook real estate groups, Google, and Airbnb listings of finished units.

What payment structure should I insist on for off-plan in Phuket? +

Push for milestone-linked payments: reservation deposit (refundable in 7–14 days for due diligence), then staged payments at SPA signing, foundation, structural completion, enclosure, and final handover. This preserves your payment leverage — if construction stalls at any milestone, you stop paying. Avoid time-based schedules where you pay regardless of construction progress, and avoid any structure requiring more than 40–50% of the purchase price before structural completion is visible on site.

Do I need a lawyer to buy off-plan property in Thailand? +

Yes — this is not optional if you want meaningful protection. An independent Thai property lawyer (not the developer's lawyer) will verify the title deed, check construction and EIA permits, review the Sale and Purchase Agreement for unfavorable clauses, confirm the developer's company registration, and advise on FET form requirements. The cost is typically ฿15,000–30,000 for full due diligence — a fraction of any property price and the only real protection available given Thailand's lack of mandatory buyer escrow.

What is an EIA and why does it matter for off-plan purchases? +

An Environmental Impact Assessment (EIA) is a government review required for significant construction projects in Thailand, particularly near coastlines or sensitive ecological zones. An approved EIA means the project has cleared environmental compliance — reducing the risk of construction injunctions, forced design changes, or regulatory shutdown. A coastal or large-scale Phuket condo project without EIA approval at time of sale is selling before it has confirmed it can legally be built as specified. This is a meaningful risk factor that your lawyer should verify before you commit.
