Thailand Property Due Diligence Checklist

Thailand Property Due Diligence Checklist #

Due diligence has always meant confirming what is being bought. In 2026, it also means confirming who is legally allowed to sell it. Thailand's 23-agency enforcement drive, the DBD screening system IBAS, and a year of tightening Department of Business Development filing orders have made seller-structure verification as routine as a title search. Better-than-Freehold™ buyers avoid this exposure because there is no nominee structure to be flagged, since the BtF™ property holding company never places a foreign party behind a Thai nominee shareholder.

What title deed class should a buyer verify first? #

The title deed class determines whether full ownership rights exist at all, and the deed is the first document a buyer should request before viewing photographs or negotiating price. Thailand issues several deed classes, and only one confers complete, transferable ownership rights recognised at the Land Department.

Chanote (Nor Sor 4 Jor) is the full title deed: GPS-surveyed boundaries, registered at the Land Department, and immediately transferable. Nor Sor 3 Gor indicates a surveyed but not yet fully adjudicated title; it can be upgraded to Chanote and is transferable, but boundary and servitude disputes are more common. Nor Sor 3 lacks that survey precision and carries higher boundary risk. Possessory rights below this tier, Sor Kor 1 for instance, confer no registrable ownership and should be treated as a warning sign rather than a starting point for negotiation.

A buyer should obtain a certified copy of the deed from the relevant Land Office, not a photocopy from the seller or agent, since only the Land Office copy confirms the deed is genuine and current.

How does an encumbrance search protect a buyer? #

An encumbrance search at the Land Department reveals mortgages, liens, usufructs, leases, and court injunctions registered against a title, any of which survive transfer of the underlying deed unless specifically cleared. A clean-looking property can carry registered constraints invisible on a casual inspection.

The search is conducted against the title deed number at the Land Office where the property is registered, and it should be run within days of a planned transfer, not weeks before, since encumbrances can be registered at any time. Buyers should look for:

• existing mortgages, which must be discharged or assumed at transfer;
• registered leases exceeding three years, which bind the new owner for the remaining term;
• usufruct or superficies rights granting a third party use of the land;
• any pending litigation against the title.

A registered mortgage the seller has not disclosed is a dispute a same-week search prevents. An encumbrance search costs little and takes little time; skipping it is the most avoidable due diligence failure.

Why does seller verification matter more in 2026? #

Seller verification now means confirming that the entity selling the property is not itself a nominee structure concealing foreign beneficial ownership, because a transaction completed with a nominee-held seller can be reversed after the fact. A title search cannot reveal this; the deed records the company as owner and says nothing about who funded it.

In 2025 the DBD set an inspection target list of 46,918 high-risk companies. Between September 2024 and July 2025, authorities took legal action against 873 nominee offenders, and the DBD put the damage to the Thai economy at THB 15.6 billion as of July 2025. Real estate and land trading sits among six sectors flagged as high risk, alongside tourism, hotels, e-commerce and logistics, agriculture, and construction.

DBD Order 2/2568 required source-of-funds documentation at registration from 1 January 2026, and high-risk registrations fell by roughly 60% in the first quarter. Order 1/2569 added a sworn PorOr.1 statement, a six-month bank-statement audit trail and in-person interviews from 1 April; false statements carry up to three years' imprisonment. High-risk registrations in early April fell 75% year-on-year. Central Registrar Order 2/2569 replaced both orders on 1 August 2026, carrying their requirements forward and tightening them in places. IBAS, a DBD screening system, cross-references shareholding, funding, directors, and advisor clusters across filings, so it catches patterns a manual review would miss.

If the seller is a Thai limited company holding the land, a buyer should request its shareholder register, capital contribution records, and confirmation of who funded the company's original purchase. Under the Foreign Business Act, a foreigner is any non-Thai natural person, foreign-registered entity, or Thai company with 50% or more foreign capital; a company sitting just under that threshold while a foreign party actually funds and controls it is the pattern IBAS is built to detect. FBA section 36 penalises this structure with up to three years' imprisonment and/or a fine of THB 100,000 to 1,000,000, applied to both the Thai nominee and the foreign beneficiary, plus court-ordered cessation of the shareholding and daily fines of THB 10,000 to 50,000. The Land Department can separately order forced disposal of the land. A buyer who purchases from a nominee-held company might see the courts later unwind the transfer, and would then have to recover funds from a seller already under enforcement.

Under the Anti-Money Laundering Act, section 60 penalises money laundering with 1 to 10 years' imprisonment, a fine of THB 20,000 to 200,000, or both, and section 61 extends the same liability to consenting directors. A proposal to make nominee abuses a predicate offence under AMLA sits inside an amendment bill that lapsed at the December 2025 House dissolution and was revived by Parliament on 15 May 2026; a House committee is still reviewing it, so this remains a direction rather than enacted law. Waiting for it to pass is not a defence; existing FBA and AMLA provisions already reach nominee sales.

Which developer checks typically apply to off-plan and new-build purchases? #

Developer due diligence confirms that a project has the legal authorisation and financial standing to deliver what has been sold, since off-plan purchases carry the added risk that construction stalls or the developer's own land title is defective. Off-plan and new-build buyers need it in addition to the title and seller checks above.

A buyer should confirm the developer holds a valid construction permit, that the underlying land title is Chanote or equivalent and free of undisclosed encumbrances, and that any required environmental impact assessment was approved before marketing began. For condominium projects, the buyer should verify the project's standing against the 49% foreign ownership quota under the Condominium Act, since units sold above that threshold cannot be registered in a foreign buyer's name regardless of the sale contract. Company registration details and filed accounts are matters of public record through the Department of Business Development. Thin capital, or a track record of late delivery on the developer's earlier projects, is reasonable grounds to walk away before signing a reservation agreement.

How should a buyer document the due diligence process itself? #

Documenting due diligence undertaken protects the buyer if a dispute arises later, since a paper trail showing that the checks above were performed, and when, demonstrates good faith and can support a claim for damages if a seller misrepresented the property's status.

A DD audit file should include dated copies of the Land Office deed search, the encumbrance search results, correspondence confirming the seller's beneficial ownership, developer permits and DBD filings, and instructions given to the conveyancing lawyer at each stage. Where a Thai lawyer is engaged, their regulator is the Lawyers Council of Thailand under the Lawyers Act B.E. 2528, and a buyer can confirm a lawyer's standing directly with the Council before relying on their opinion. A file assembled as the transaction proceeds costs an afternoon. Reconstructing one after a dispute has arisen costs considerably more.

How does Better-than-Freehold™ reduce due diligence exposure at the outset? #

Compliance comes first. The Better-than-Freehold™ structure is designed so the seller-verification problem does not arise. Thailand Investor Network, a 100% Thai-owned property holding and management company with its own funded shareholder capital, holds the legal title directly, with no foreign control and nothing in its shareholding for IBAS to flag.

Four principal instruments carry the buyer's position: a 30-year lease and a first-priority mortgage, both registered at the Land Department; a separate Option Agreement appended to the mortgage; and a share pledge. The two registrations give a buyer's due diligence file a documented trail from day one.

Security follows. SPH Trustees Ltd, an offshore trustee whose Labuan FSA licence is in progress, holds investor rights and conducts source-of-funds verification at onboarding, while Clear Blue Security Agents mediate and enforce investor rights independently, without depending on the Thai courts.

The benefits complete the picture. The structure supports financing to 50% loan-to-value (expected H1 2027), resale by assignment of your trust interest without the seller-verification burden that a direct nominee-company purchase carries, and succession without Thai probate, since the corporate trustee, SPH Trustees Ltd, does not die and the investor's rights pass by assignment. Explore how BtF™ works to see how the four instruments fit together.

Expert Guidance #

Due diligence errors usually surface after funds have transferred. Better-than-Freehold™ advisers can review a specific title deed, seller structure, or developer filing against current Land Department and DBD requirements before a buyer commits.

Conclusion #

Thailand property due diligence in 2026 has four parts: title deed class, encumbrance search, seller structure, and developer standing. The first two have always mattered; the third is now unavoidable given the DBD's inspection target list of 46,918 high-risk companies and DBD filing orders that have cut high-risk registrations by more than half. A buyer who completes each check and documents having done so is far less exposed to a transaction unwinding later.
