Title, chanote, and foreign ownership limits: the Thailand property due diligence checklist for 2026

Thailand commercial property due diligence has one foundational constraint with no Western equivalent: foreigners cannot own land in Thailand under the Land Code. Commercial structures for foreign investors rely on long-term leasehold, Thai-majority company ownership (with nominee risk), or BOI promotion exceptions. Every diligence starts by confirming the structure is legally sound and then verifying the underlying land title is Chanote.

Thailand commercial property transfer costs for domestic ownership transfers: 2% transfer fee (assessed value, split by custom); 3.3% Specific Business Tax (SBT, if held under 5 years) or 0.5% stamp duty (if held over 5 years); plus withholding tax (1% of assessed value for corporate sellers, graduated for individuals). Total costs: 5-6% for short-hold transfers, 3-4% for long-hold transfers. For leasehold commercial (common for foreign-structured deals): lease registration fee is 1% of total lease consideration + 0.1% stamp duty.

All Thailand commercial title verification starts with confirming the category of land document. The highest and only commercially acceptable title document is a Chanote (Nor Sor 4 Jor) - GPS-surveyed with precisely defined boundaries, fully transferable and mortgageable. Nor Sor 3 Gor (confirmed certificate) is broadly acceptable but less precise. Nor Sor 3, Por Bor Tor 5, Sor Por Kor, and other lesser documents are NOT acceptable for commercial acquisition or as mortgage security; they are possession certificates, not ownership title.

Thailand Department of Lands (Krom Thi Din) maintains the official land register; title search and any transfer registration must be conducted at the Provincial Lands Office (Samnak Ngan Thi Din Changwat) in the province where the land is located. Bangkok commercial title is handled by the Bangkok Metropolitan Administration Lands Office and district-level offices.

Set up a real estate data room before advisors engage. Load Chanote title, lease agreement, BOI promotion documents, building permit, occupancy certificate, environmental records, and lease files before diligence opens.

Where Thailand property deals go wrong

Not every check carries the same weight. The table below sorts risks by deal impact - dealbreakers first, then what moves the price, then basic hygiene - so your Thai attorney and advisor know what to clear first.

Thailand commercial property due diligence checklist

The table ranked risks by severity. This is the full checklist to work through, grouped by area.

Title - Chanote verification and structure

• The first diligence task for any Thailand commercial acquisition is confirming the land title document category; request the original Chanote (Nor Sor 4 Jor) document from the seller and conduct an official title search at the competent Provincial Lands Office (Samnak Ngan Thi Din Changwat)
• Official title search: the back of the Chanote document shows registered encumbrances at the time the document was last issued; the current registered status (including any recently registered mortgages or encumbrances) can only be confirmed by a live search at the Provincial Lands Office; conduct this search as close to closing as possible - ideally on the same day
• Chanote authenticity: Thai Chanote document forgery has been documented; verify the document's authenticity through the Provincial Lands Office; the Department of Lands can confirm whether the Chanote number and details match their records
• Nor Sor 3 Gor confirmation: if the title is Nor Sor 3 Gor rather than Chanote, confirm from the Provincial Lands Office that upgrade to Chanote is not currently in process (which can affect boundaries) and that the boundaries have been formally confirmed with neighboring parcels; Nor Sor 3 Gor is generally bankable but confirm with the intended lender before proceeding
• No other title: Por Bor Tor 5, Sor Por Kor, Sor Kor 1, NS 2, and all other lesser documents are not acceptable for commercial acquisition; if the seller presents any of these, walk away or require upgrade to Chanote before closing

Give each advisor a scoped link in Ellty. Thai real estate attorney sees Chanote title, encumbrance search, and structure documents. BOI specialist sees promotion certificate. Building inspector sees building permit and occupancy certificate. Environmental consultant sees PCD and EIA records. Lender sees title, structure legal opinion, and valuation.

Foreign ownership structure - legal opinion required

• Every foreign-structured Thailand commercial acquisition requires a specific written legal opinion from Thai counsel on the proposed structure before any deposit; the opinion must address: (1) whether the structure complies with the Foreign Business Act, Land Code, and applicable regulations; (2) nominee shareholder risk and mitigation; (3) lease renewal enforceability
• Thai company structure: a Thai company with 51%+ Thai shareholders can hold land legally; the Thai shareholders must be genuine investors with financial capacity to have invested the stated capital; nominee arrangements where Thai shareholders hold shares for the benefit of a foreign investor are illegal and can result in land revocation; DBD and Department of Lands conduct periodic investigations; confirm from Thai counsel that the proposed structure is defensible and not nominee-based
• Long-term leasehold: a 30-year registered commercial lease is the safest foreign-accessible structure for commercial land use; contractual renewal clauses for additional 30-year periods provide contractual protection but are enforced as breach of contract remedies, not as property rights; for any leasehold commercial acquisition, confirm with Thai counsel the practical enforceability of the renewal provisions under current Thai court practice
• BOI promotion: if the seller holds BOI promotion that grants land ownership rights, confirm the promotion is still active, the promoted business activities still qualify, and whether the BOI promotion and associated land rights transfer to a buyer; BOI-promoted land rights are tied to the promoted business activity and may not be freely transferable
• Condominium units: foreigners can own condominium units (as opposed to land) in Thailand; confirm that foreign unit ownership does not exceed 49% of total floor area in the building as of the acquisition date; the condominium juristic person (niti buk kon of the condominium) can confirm current foreign ownership percentage

Building permit and occupancy certificate

• Request building construction permit (bai anuyat ko sang) and building occupancy certificate (bai ror bor, also called use certificate) from seller; if a multi-stage construction: request all stage-specific permits
• Bangkok Metropolitan Administration (BMA) for Bangkok; municipality (tesaban) or SAO (Ongkan Borihan Suan Tambon) for provincial locations
• Compare the building as-built against the building permit and occupancy certificate: any floor area, additional floors, or structural changes beyond the permit are unauthorized and can be ordered modified or demolished by the local building authority
• For large commercial developments (typically over 10,000 sqm, or hotels over 80 rooms, or condominiums over 8,000 sqm): confirm EIA (Environmental Impact Assessment) approval from ONEP was obtained before construction commenced; development without required EIA approval creates legal vulnerability
• Building age and seismic/structural: while Thailand is not in the same seismic category as Taiwan or Japan, northern Thailand (Chiang Mai, Chiang Rai, Mae Sot) has documented seismic activity; for commercial in northern Thailand: commission structural assessment

Load Chanote title, lease agreement, BOI promotion certificate, building permit, occupancy certificate, EIA approval, PCD/IEAT contamination records, and lease files into Ellty. Track which advisors review which documents. Monitor the Thai attorney's review of the structure legal opinion most closely.

Transfer taxes - SBT vs. stamp duty structure

• Confirm how long the seller has held the property and whether the seller is an individual or company; this determines whether SBT (3.3%) or stamp duty (0.5%) applies
• SBT applies if: (a) any corporate seller (regardless of holding period), or (b) any seller (individual or corporate) who has held less than 5 years; SBT rate is 3.0% of the higher of assessed or transaction value, plus 0.3% municipality tax = 3.3% total
• Stamp duty applies if: an individual seller who has held the property as registered owner for over 5 years and SBT does not apply; stamp duty 0.5% of assessed value
• Withholding tax on seller: 1% of assessed value for corporate sellers; for individual sellers, calculated on a graduated scale based on assessed value and number of years held (essentially a withholding on the deemed income from the sale); confirm this is the seller's obligation and is being factored into net price negotiations
• Transfer fee: 2% of the assessed value (assessed by Department of Lands, typically lower than market); by custom split 50/50 between buyer and seller, negotiable in commercial transactions
• Lease registration: for any commercial leasehold acquisition, the lease registration fee is 1% of total lease consideration + 0.1% stamp duty on the registered lease document

Compare UAE's commercial property due diligence process for emerging market commercial strategy. Thailand and the UAE share similar structures for foreign buyers - both limit land ownership to nationals/designated zones and both use leasehold structures for foreign commercial investment - but differ on transfer taxes (UAE has no national transfer tax, Dubai charges 4% DLD fee, vs. Thailand's 5-6% combined cost), legal system (UAE civil law plus DIFC common law vs. Thailand's mixed civil law system), and market maturity.

How due diligence works in Thailand

Step 1 - Chanote title and structure legal opinion

Day one: initiate official title search at Provincial Lands Office and commission Thai counsel legal opinion on the proposed foreign ownership structure (if buyer is foreign).

Don't pay any deposit before the Chanote is verified and the structure opinion is in hand. For BOI-structured deals: confirm BOI promotion status independently from the BOI authority.

Step 2 - Building permits, environmental, and flood

Request building permit and occupancy certificate from seller. For large commercial (over 10,000 sqm): confirm EIA approval. Commission Phase I ESA with PCD/IEAT review for any industrial-zone-adjacent commercial.

Confirm flood exposure for any Bangkok suburban, Chao Phraya corridor, or Central Thailand commercial - check 2011 flood inundation maps.

Step 3 - Leases, zoning, and AML

Abstract all commercial leases. Confirm which leases over 3 years are registered at the Department of Lands. Confirm Bangkok city plan zone and FAR/BCR limits.

Run AMLO-compliant AML/KYC on all principals. Run OFAC and sanctions screens. For cross-border transactions: confirm Bank of Thailand FX approval availability for repatriation.

Step 4 - Transfer costs and closing

Confirm SBT vs. stamp duty treatment. Calculate transfer fee allocation (2% of assessed value). Closing takes place at the Provincial Lands Office in Thailand; the Thai attorney and the parties must be physically present (or represented by power of attorney) for the transfer registration.

Load all files into Ellty before advisors engage. Thai attorney sees title and structure documents. BOI specialist sees promotion certificate. Lender sees legal opinion, title, and valuation.

What makes Thailand different

Thailand's foreign land ownership prohibition under the Land Code is not a technical rule that can be easily worked around; it is a fundamental restriction that shapes every commercial real estate acquisition by a foreign investor in Thailand. The Thai majority company structure (51% Thai shareholders, 49% foreign) is legally permitted but operationally fragile: if the Thai shareholders are nominees (holding shares for the foreign investor's benefit with no genuine independent economic interest), the arrangement is illegal under both the Foreign Business Act and the Land Code, and both the Department of Land and the Department of Business Development actively investigate and dismantle nominee structures. A nominee structure that was established years ago and has operated without enforcement action is not a safe acquisition target - it remains illegal and the enforcement risk transfers to a buyer. Require a specific written legal opinion from independent Thai real estate counsel before completing any acquisition of land held through a Thai company structure; the opinion must address the specific Thai shareholders' circumstances, capital contribution records, and the overall structure's defensibility under current Thai enforcement practice.

The 2011 Thailand floods were the most extensive flooding event in Thailand in 70 years and the fourth costliest natural disaster in world history at the time. The flooding was triggered by unusually heavy monsoon rains that overwhelmed the Chao Phraya River catchment; approximately 13.6 million people were affected across 65 provinces; economic damage exceeded USD 45 billion. The flooding was particularly severe in the industrial estates of Ayutthaya, Pathum Thani, and Nonthaburi - major manufacturing zones where Japanese and other foreign manufacturers operated large facilities. Bangkok's inner core was largely protected by the ring dike system, but Bangkok's northern suburbs (Don Mueang, Lak Si, Bang Khen) and large areas of Pathum Thani province were inundated for weeks. Commercial buyers of Bangkok suburban, Central Thai, or Ayutthaya commercial property should specifically map the target parcel against 2011 flood inundation records from the Bangkok Metropolitan Administration and Royal Irrigation Department. Thailand's flood management infrastructure has been upgraded since 2011, but the underlying hydrology has not changed and flooding in the Chao Phraya basin remains an active CRE risk.

The Chanote verification process - checking the Chanote document authenticity at the Provincial Lands Office and conducting a same-day title search at closing - is a standard step in Thai real estate practice that has no equivalent in many developed markets. In most Western jurisdictions, title examination is done through a lawyer reviewing a government database weeks before closing, with title insurance as the backstop. In Thailand, the relevant authority is the Department of Lands office in the relevant province, and the official record of encumbrances is the back of the physical Chanote document that must be confirmed in real time at the Lands Office. Conducting the title search weeks before closing is insufficient; encumbrances can be registered at any time between the search and the transfer. Thai practice is to conduct the final search on the day of transfer and complete the transfer registration at the same Lands Office appointment. This same-day procedure is not a formality - it is the primary fraud and encumbrance protection mechanism in Thai property law.

Timeline and cost in Thailand

Weeks 1-2 cover kickoff: initiate official title search at Provincial Lands Office, request Chanote document, commission Thai counsel legal opinion on ownership structure (if foreign buyer), building permit and occupancy certificate request, BOI promotion status confirmation (if applicable), Phase I ESA commission, PCD/IEAT database check, Bangkok city plan zone confirmation, lease abstraction, AML/KYC, and Bank of Thailand FX clearance assessment. Legal fees in this phase: USD 5,000-20,000.

Load all files into Ellty before advisors engage. Standard Thailand commercial: 45-90 days. BOI promotion clearance: 2-6 weeks. EIA approval confirmation: 2-4 weeks for existing developments.

Weeks 2-6 cover deep review: Chanote authenticity verification, full encumbrance search, structure legal opinion delivery, building permit vs. as-built comparison, occupancy certificate status, Phase I ESA delivery, PCD contamination records, flood exposure assessment, zone compliance confirmation, SBT/stamp duty analysis, lease registration status, withholding tax calculation, and lender pre-approval process. Costs in this phase: USD 10,000-30,000.

Weeks 6-12 handle resolution: structure remediation (if nominee issues identified), mortgage releases, lease registration (if required), EIA compliance confirmation, flood risk mitigation measures, transfer tax payment at Lands Office, and closing at Provincial Lands Office.

Thailand total transaction costs for commercial ownership transfer: 2% transfer fee (assessed value, typically split 50/50) + 3.3% SBT or 0.5% stamp duty + withholding tax (1% for corporate sellers). For a Thai company-to-Thai company transfer of commercial property assessed at 100 million THB, typical transaction tax burden: 2% + 3.3% + 1% = approximately 6.3% of assessed value (noting assessed value is typically 50-80% of market value). Thai attorney fees, due diligence, and advisory fees add 1-3% of transaction value.
