How to Verify a Property Developer in Phuket: Due Diligence Checklist

Developer due diligence is the single most important step in any Phuket property purchase — especially for off-plan investments. A thorough background check can save you from financial loss, construction delays, and legal nightmares. This guide provides a complete, actionable checklist for verifying any developer in Phuket.

Why Developer Verification Matters

Phuket's property market has seen remarkable growth, attracting both reputable developers and opportunistic operators. While most developers deliver quality projects, the industry has experienced:

• Project abandonments during economic downturns (2008 crisis, COVID-19)
• Significant construction delays (6–24 months beyond promised dates)
• Quality issues where finished units differ substantially from marketing materials
• Financial difficulties where developers run out of money mid-construction
• Legal complications from improper permits or land titles

A few hours of due diligence can protect an investment worth millions of baht.

Check 1: Company Registration (DBD)

The Department of Business Development (DBD) maintains records of all registered Thai companies.

How to Check:

1. Visit www.dbd.go.th (English version available)
2. Search by company name or registration number
3. Download the company's profile and financial statements

What to Look For:

Document	What It Tells You
Company profile	Registration date, registered capital, directors, shareholders
Balance sheet	Assets, liabilities, equity — is the company solvent?
Income statement	Revenue and profit trends — is the company profitable?
Director list	Who runs the company? Any changes recently?
Shareholder list	Who owns the company? Foreign or Thai majority?
Objectives	What is the company authorized to do?

Red Flags:

• Registered capital under 10 million THB for a developer building a large project
• Frequent director changes — may indicate internal problems
• Losses for 2+ consecutive years — financial distress
• Company registered less than 3 years ago — no track record
• Registered address is a residential home — not a professional operation
• Multiple companies with similar names — possible corporate shell game

Check 2: EIA Permit (Environmental Impact Assessment)

An EIA is a mandatory environmental study required for certain types of developments.

When Is EIA Required?

• Condominium projects with 80 or more units
• Projects on land larger than 100 rai (160,000 sqm)
• Projects near coastline, national parks, or protected areas
• Projects that may impact water resources or marine environments

How to Verify:

• Ask the developer for the EIA approval certificate
• Verify with the Office of Natural Resources and Environmental Policy and Planning (ONEP)
• Check the ONEP website for approved projects: www.onep.go.th

Why It Matters:

• Without EIA approval, the project cannot legally obtain a construction permit
• Selling units in a project without EIA (where required) is illegal
• If EIA is denied after you have paid, getting a refund can be extremely difficult
• EIA process takes 6–12 months — projects that start selling before EIA are high risk

Red Flags:

• Developer claims EIA is "in progress" but is already selling units
• EIA was obtained for a different project design than what is being marketed
• Developer cannot provide the EIA certificate number for verification

Check 3: Construction Permit

A construction permit is issued by the local municipality (Tessaban, OrBorTor, or City Hall).

How to Verify:

• Request a copy of the construction permit from the developer
• Visit the local municipality office and verify the permit number
• Confirm the permit matches the actual project plans (number of floors, units, building area)

What the Permit Should Include:

• Building height and number of floors — must match what is being sold
• Total building area — confirms the project scope
• Number of units — should match the sales brochure
• Approved building use — residential, commercial, or mixed-use
• Expiration date — construction permits are valid for a specific period

Red Flags:

• No construction permit exists (developer says it is "coming")
• Permit is for a different number of units or floors than marketed
• Permit has expired and not been renewed
• Construction has begun without a permit (illegal)

Check 4: Chanote Title Deed Verification

The Chanote (Nor Sor 4 Jor) is the highest form of land title in Thailand.

How to Verify:

1. Obtain a copy of the Chanote from the developer
2. Visit the local Land Office (where the land is registered)
3. Request a title search (cost: 100–500 THB)
4. Verify: owner name, land area, location, any encumbrances

What to Confirm:

Check	Why
Title type is Chanote	Highest security; GPS-surveyed
Land is registered to the developer	Not a third party or individual
No mortgages or liens	Bank loans on the land could affect your unit
No legal disputes	Pending lawsuits or claims
Land area matches project plans	Ensures the developer owns enough land
Zoning permits residential use	Some land is agricultural or government-reserved
No encroachment on public land	Building on government land = demolition risk

Red Flags:

• Land title is Nor Sor 3 or lower (less secure than Chanote)
• Land is mortgaged to a bank (common but must be released before unit transfer)
• Multiple Chanote numbers for what appears to be a single project (land assembly issues)
• Title is under an individual's name rather than the development company

Check 5: Previous Projects Track Record

The best predictor of future performance is past performance.

How to Research:

1. Ask the developer for a list of completed projects
2. Visit completed projects in person — check build quality, common areas, landscaping
3. Talk to current owners — ask about their experience, any issues, timeline accuracy
4. Check online reviews — Facebook groups (Phuket Property, Phuket Expats), Google Reviews, Trustpilot
5. Search Thai legal databases — for any lawsuits involving the developer

Questions to Ask Current Owners:

• Was the project delivered on time?
• Did the finished unit match the sales materials?
• How responsive is the management/after-sales team?
• Are there any ongoing maintenance or quality issues?
• Would you buy from this developer again?

Assessment Criteria:

Criteria	Good Sign	Bad Sign
Projects completed	3+ delivered on time	0 completed projects
Owner satisfaction	Positive reviews, repeat buyers	Complaints, lawsuits
Build quality	Materials match specs, solid finishes	Cracks, leaks, cheap fittings
After-sales service	Responsive, honors warranties	Unresponsive, disputes warranties
Timeline accuracy	Within 3 months of promised date	12+ months late

Check 6: Financial Health

A developer's financial stability determines whether they can complete your project.

Key Financial Metrics:

Metric	Healthy Range	Warning Level
Debt-to-equity ratio	Below 2:1	Above 3:1
Current ratio	Above 1.5	Below 1.0
Annual revenue growth	Positive	Declining for 2+ years
Net profit margin	Above 10%	Negative
Registered capital	10M+ THB	Under 5M THB

How to Access Financial Data:

• DBD website — Free basic financial summary
• DBD e-Service — Detailed financial statements (small fee)
• Ask the developer directly — Reputable developers will share financials
• Industry contacts — Banks, lawyers, and agents often know the financial health of major developers

Check 7: Escrow Account

An escrow account is a separate bank account where buyer funds are held, released to the developer only upon reaching construction milestones.

What to Verify:

• Does the developer use an escrow account? (Not all do — it is not legally required in Thailand)
• Which bank holds the escrow? (Major Thai banks: Bangkok Bank, Kasikorn, SCB)
• What are the release conditions? (Tied to construction milestones)
• Is the escrow agreement part of your purchase contract?

Reality Check:

Many Phuket developers, including reputable ones, do not use escrow accounts. Buyer funds go directly into the developer's operating account. This is legal but increases buyer risk. If a developer DOES use escrow, it is a strong positive signal.

Check 8: Lawyer Involvement

Never rely on the developer's lawyer to protect your interests.

Your Lawyer Should:

1. Review the Sale and Purchase Agreement before you sign
2. Conduct an independent title search at the Land Office
3. Verify all permits and approvals
4. Check for any legal disputes involving the developer
5. Ensure the contract includes adequate buyer protections:
   • Penalty clauses for late delivery
   • Specification guarantees
   • Refund conditions if the project is not completed
   • Defect liability period (typically 1–2 years)

Lawyer Costs:

• Contract review only: 15,000–30,000 THB
• Full due diligence: 30,000–50,000 THB
• Comprehensive (review + registration + company setup): 50,000–80,000 THB

This is one of the best investments you will make. A 40,000 THB lawyer fee can protect a multi-million baht purchase.

Red Flags: Warning Signs to Walk Away

If you encounter any of these, proceed with extreme caution or walk away entirely:

1. Pressure to sign quickly — "This price is only available today" is a sales tactic, not a genuine limitation
2. No construction permit — Selling without permits is illegal
3. Unrealistic guaranteed returns — 10%+ guaranteed yields are unsustainable
4. No completed projects — First-time developers carry the highest risk
5. Developer refuses to provide documents — Transparency is non-negotiable
6. Significantly below-market pricing — If it seems too good to be true, it usually is
7. No independent lawyer allowed — A developer who discourages independent legal review has something to hide
8. Non-refundable large deposits — Reasonable reservation deposits are 50,000–200,000 THB, not millions
9. Foreign nominee shareholders in the Thai company — This suggests the company structure may not withstand legal scrutiny
10. Construction started before permits — Indicates disregard for regulations
