Thailand DBD 2026: Two-Pillar Verification Regime for Foreign-Participation Companies

Matter Snapshot

• Client profile: Foreign investor or cross-border group planning to incorporate a Thai limited company or partnership in 2026, or already operating through a Thai-majority limited company or partnership and contemplating a director change, signatory change, partner amendment, or other post-incorporation corporate filing.
• Triggering event: Two DBD orders issued under the enabling authority of the Ministerial Regulation on Establishment of the Partnership and Company Registration Office B.E. 2553 (2010). Together they extend source-of-funds and investment-authenticity verification across the full company life cycle.
• Core risk: The filing signatory — at incorporation, the applicants; at amendment, the managing partner or authorized director — bears the documentary and personal-liability exposure. The Investment Confirmation Letter template attached to Order 1/2569 cites three specific statutory provisions (Foreign Business Act §36, Thai Penal Code §§137 and 267) as the penalty framework for false declarations.
• Time sensitivity: Both measures apply prospectively to covered transactions. Existing companies that do not initiate a covered incorporation or amendment are not directly triggered. However, any future amendment that introduces foreign equity, a foreign partner, or a foreign authorized director will engage Order 1/2569. Internal evidence — source of funds, share payment records, dividend history, board and signatory records — should be reconstructed before any triggering filing is lodged.

Source: This article is prepared by the Lexcelsiam Regulatory Intelligence Desk based on the full Thai text of DBD Central Partnership and Company Registration Office Orders No. 2/2568 and No. 1/2569, the attached Investment Confirmation Letter template, the Thailand Foreign Business Act B.E. 2542 (1999), and the Thai Penal Code.

From 2026, Thailand's Department of Business Development (DBD) has moved anti-nominee enforcement from a single-point incorporation check to a full life-cycle verification regime. The shift is important for two reasons. First, it captures amendment filings that previously escaped substantive review. Second, it anchors personal liability on named filing signatories through the specific criminal provisions cited in the Confirmation Letter template.

For investors using the familiar Thai 51% / foreign 49% structure, the structural question remains unchanged — whether Thai shareholders genuinely invest, bear risk, and receive returns. The procedural question is newly material — whether the company can, at every future registration event, produce the specific documentary evidence that the two orders now require.

I. The Two-Pillar Architecture

The 2026 regime operates through two coordinated orders issued by the same authority — the Central Registrar of the DBD. They cover different stages of a company's life cycle and require different documents, but their policy target is unified.

Both orders are issued under the same enabling authority — Clause 3 paragraph 3 of the Ministerial Regulation on Establishment of the Partnership and Company Registration Office, Appointment of Registrars, and Rules for Registration B.E. 2553 (2010) — and both are signed by the same Director-General of the DBD, acting as Central Registrar. The coordinated timing, shared authority, and complementary documentary requirements mark this as a deliberate two-stage closure of the nominee loophole rather than two unrelated updates.

II. Pillar One — Order No. 2/2568 (Incorporation, effective 1 January 2026)

Order 2/2568 prescribes supporting documents for applications to register the establishment of a new partnership or limited company where the formation involves foreign participation.

1. Scope: which incorporations are covered

The order applies in either of two scenarios. The trigger is read in the alternative, not cumulatively.

• Scenario (1): The new partnership or limited company has foreign partners or shareholders holding less than 50% of the investment or registered capital. This captures the classic Thai-majority / foreign-minority formation.
• Scenario (2): The new limited company has no foreign shareholders at all, but a foreigner is named as an authorized director with signing power, either alone or jointly.

Scenario (2) is often missed in market commentary. An all-Thai-shareholder incorporation that appoints a foreign director as authorized signatory is covered, even without any direct foreign equity.

2. The 3-month bank statement requirement

For every Thai-national partner or shareholder in a covered incorporation, the applicant must submit a bank statement issued by the bank covering the 3 months preceding the date of share-capital payment, drawn from the specific account used to make that payment.

The order requires two substantive elements to appear in the statement:

• A withdrawal or transfer matching the amount of the share subscription or share-price payment.
• The date of that payment.

This is not a generic balance certificate. The order is drafted to function as a forensic source-of-funds trace. The DBD wants to see that the money used to pay for the Thai shareholder's shares actually left the Thai shareholder's own bank account, on the day the capital was paid, in the specific amount paid.

3. Practical implications

Two implications follow:

• Thai shareholders must be in a position to evidence the source of the funds in that payment account. If the money arrived from a foreign-linked account shortly before the capital payment date and left immediately after, the 3-month window will expose the pattern.
• Deferred or back-dated capital payments are not practical under this regime. The statement must be anchored to the actual payment date.

Order 2/2568 replaces Order No. 205/2555 of 22 November 2555 (2012), which had prescribed a narrower set of supporting documents for incorporation. The scope of Thai-shareholder evidence required has meaningfully expanded.

III. Pillar Two — Order No. 1/2569 (Amendment, effective 1 April 2026)

Order 1/2569 extends the verification focus from incorporation to amendment registrations. It introduces the Investment Confirmation Letter as the required document.

1. Scope: which amendments are covered

The order applies in either of two scenarios.

• Scenario (1) — partnership amendments: A partnership whose partners were previously all Thai nationals, or whose foreign partners previously contributed 50% or more of the capital, applies for an amendment that results in foreign partners contributing less than 50% without a foreigner serving as managing partner. The registrar must require the managing partners signing the application to attach an Investment Confirmation Letter per the template annexed to the order.
• Scenario (2) — limited company director and signatory amendments: A limited company whose authorized signatory directors were previously all Thai applies for an amendment of directors, number of signatory directors, or names of signatory directors that results in a foreigner becoming an authorized director able to bind the company alone or jointly. The registrar must require the directors signing the application to attach an Investment Confirmation Letter.

The common thread is a transaction that moves the company from a Thai-majority / Thai-signatory position to one where foreigners hold minority equity or signing rights — the exact transitional pattern in which nominee structures are typically assembled after an initial Thai-only incorporation.

2. What the Investment Confirmation Letter says

The template annexed to Order 1/2569 is a single-page sworn declaration signed by the managing partners or authorized directors filing the amendment. On its face, the declarant confirms:

• All partners have genuinely invested and made genuine capital contribution / all shareholders have genuinely invested and paid for their shares in full; and
• No Thai national has assisted, supported, or jointly conducted business with foreigners in a nominee capacity.

The letter further states the declarant's acknowledgement that the use of Thai nationals as nominees constitutes an offence under Foreign Business Act §36, and that providing information inconsistent with the facts to the Partnership and Company Registrar constitutes a false statement to an official under Penal Code §137 and causing an official to record false information under Penal Code §267. The declarant consents to the registrar sharing the information with law enforcement authorities for further action.

3. Why this is a concentration of personal liability

Before Order 1/2569, enforcement against nominee structures required investigators to reconstruct funding flows and control arrangements. Under the new mechanism, the signatory of the amendment filing is on record with a sworn declaration tied to the three specific statutory offences named in the template. The Confirmation Letter does not create new offences, but it converts the filing signature into a formal statement that can itself be used as evidence in any subsequent inquiry.

IV. The Policy Objective — Stated in the Order Itself

The preamble to Order 1/2569 articulates the policy motive directly, not as outside commentary. The official Thai text records:

ด้วยปรากฏว่ามีการใช้คนไทยเป็นตัวแทนอำพรางในการประกอบธุรกิจแทนคนต่างชาติ (นอมินี) อันส่งผลกระทบสร้างความเสียหายต่อประชาชนและความมั่นคงทางเศรษฐกิจของประเทศ จึงจำเป็นต้องกำหนดมาตรการจำเป็นเร่งด่วน…

In English: "Whereas it has appeared that Thai nationals are being used as concealment agents in business activity conducted on behalf of foreigners (nominees), which affects the public and the country's economic security, it has become necessary to prescribe urgent measures…"

Order 2/2568's preamble is more administrative in tone — improving the criteria and procedures for registration — but its operative scope, targeting Thai-majority / foreign-minority formations and all-Thai-shareholder companies with foreign directors, is unmistakably oriented toward the same pattern.

Reading the two orders together, the regulatory objective is to verify, at both incorporation and amendment stages, that any Thai national appearing on the share register or in the directorship is genuinely participating as principal rather than holding on behalf of an undisclosed foreign principal.

V. The Statutory Penalty Framework

The Investment Confirmation Letter template names three specific provisions. Practitioners and corporate officers should distinguish them precisely, because their penalty ranges differ materially.

• Foreign Business Act B.E. 2542 §36 — nominee arrangements. Any Thai national or Thai juristic person who assists, supports, or jointly conducts business with a foreigner in a nominee fashion to enable the foreigner to operate a business in circumvention of the Act is liable to imprisonment not exceeding 3 years, or a fine of THB 100,000 to THB 1,000,000, or both.
• Thai Penal Code §137 — false statement to an official. Whoever makes a false statement to an official whose duty is to enquire into or record the statement is liable to imprisonment not exceeding 6 months, or a fine not exceeding THB 10,000, or both.
• Thai Penal Code §267 — causing an official to record false information in a public document. Whoever causes an official to record false information in a public document is liable to imprisonment not exceeding 3 years, or a fine not exceeding THB 60,000, or both.

Two points are worth noting for practitioners:

• The "3-year" exposure cited in market commentary is not a single penalty. It is either the FBA §36 nominee penalty (with an additional substantial fine range) or the Penal Code §267 false-public-document penalty. Penal Code §137 by itself is a maximum 6-month provision.
• These penalties attach to the directors and managing partners who sign the filing. They do not attach automatically to passive shareholders or to Thai partners whose only role is to appear on the register. Criminal exposure of the signatory turns on the signatory's actual knowledge and the accuracy of the declaration.

VI. 51/49 and Other Structures Under Substantive Review

Thai law does not prohibit foreigners and Thai nationals from jointly investing in a Thai company. A Thai 51% / foreign 49% structure is not automatically unlawful. The higher-risk arrangements — those likely to fail substantive review under the 2026 regime — are more specific:

• Thai shareholders lack actual financial capacity, and the share capital is provided directly or indirectly by the foreign investor.
• Thai shareholders do not participate in business operations or bear commercial risk, but only receive a fixed annual fee.
• Profits appear to be distributed according to shareholding but are routed back to the foreign party through loans, service fees, consulting fees, or other related-party arrangements.
• The foreign shareholder holds no more than 49% but controls the company through director signatory rights, shareholder agreements, powers of attorney, loans, preference rights, or veto rights.
• Thai shareholders cannot explain their source of funds, investment purpose, or commercial participation.

Under the 2026 incorporation regime, the first and fifth of those patterns are directly exposed by the 3-month bank statement requirement. Under the 2026 amendment regime, the Investment Confirmation Letter forces the signing director or managing partner to take a position on the remaining patterns. Arrangements that may once have passed as market practice will be harder to defend.

VII. Immediate Actions Before a Triggering Filing

For foreign-invested businesses already operating in Thailand — or planning to incorporate in 2026 — an internal compliance review along four lines is advisable before any triggering incorporation or amendment filing is lodged.

1. Funds

Confirm whether each Thai shareholder genuinely paid for their shares from their own account, whether their source of funds is reasonable, and whether there were any foreign-funded advances, name-lending payments, or circular fund flows. For an incorporation governed by Order 2/2568, the Thai shareholder's payment account bank statement for the 3 months preceding capital payment must independently evidence a withdrawal or transfer matching the share price, on the payment date.

2. Economics

Review dividend history, shareholder loans, service fees, management fees, consulting fees, and other related-party transactions. If Thai majority shareholders have never received real economic returns, the risk profile increases and an Investment Confirmation Letter at the next amendment becomes harder to defend.

3. Control

Review board composition, signatory arrangements, company seal control, bank account authority, powers of attorney, shareholder agreements, and decision-making procedures to determine whether foreigners have practical control that is inconsistent with the registered structure.

4. Documents

Check whether company registration records, shareholder registers, meeting minutes, payment evidence, tax filings, financial statements, and internal agreements are consistent with one another. Nominee risk is usually exposed through contradictions across documents, not through any single document alone.

VIII. Compliance Pathways for Foreign Investors Entering Thailand

Against the 2026 verification regime, foreign investors should consider the following alternatives to thinly capitalized Thai-majority structures.

1. Use Real Thai Commercial Partners

If the business is in a foreign-restricted sector, investors should identify Thai partners with genuine capital capacity, industry resources, and operational participation. A defensible joint venture should reflect shared funding, shared operations, shared risk, and shared returns — each of which the 2026 documentation can evidence rather than contradict.

2. Assess BOI, FBL, or Other Approval Routes

For technology, manufacturing, renewable energy, digital services, R&D, regional headquarters, and similar projects, investors should assess whether BOI promotion is available. BOI-promoted companies may receive a foreign shareholding ratio exemption under Investment Promotion Act §12 for the promoted activity, meaning the FBA equity cap does not constrain the structure. BOI companies remain subject to DBD registration procedures — the 2026 verification documents still apply to their incorporations and amendments — but foreign majority equity is not a legal defect where BOI has granted the exemption. For restricted businesses that cannot obtain BOI promotion, a Foreign Business License or another statutory route should also be considered.

3. Rebuild Asset-Holding Arrangements

For real estate, factories, warehouses, hotels, condominiums, or other asset-heavy projects, investors should avoid using nominal Thai companies to bypass land or foreign ownership restrictions. More transparent structures may include long-term leases, superficies, condominium foreign-quota planning, BOI land rights, or other lawyer-reviewed asset arrangements.

IX. Conclusion: Thai Foreign Investment Compliance Is Now About Business Substance

The 2026 two-pillar regime sends a clear message: Thai corporate registration is no longer a purely formal filing exercise. The DBD has incorporated source of funds, authorized signatory powers, actual control, and investment authenticity into the review framework, and has anchored personal liability on named filing signatories through the specific statutory provisions cited in the Investment Confirmation Letter template.

For foreign investors, the question is no longer how to make Thai ownership appear to exceed 50%. The question is whether the company can prove, at both incorporation and every subsequent amendment, that each Thai shareholder is a genuine investor and each Thai director is a genuine decision-maker.

A 51/49 structure can still have lawful uses, but it must be built on a real commercial relationship. Thai shareholders who do not fund, participate, receive returns, or bear risk will provide little protection in a substantive enforcement environment. Transparent, explainable, and auditable corporate structures are now a baseline requirement for long-term foreign investment in Thailand.

FAQ

Q1. Is a Thai 51% / foreign 49% company structure now prohibited?

A1. No. A 51/49 structure is not automatically unlawful. The key question is whether the Thai shareholders genuinely fund their shares, bear business risk, and receive economic returns. A Thai shareholder who merely lends a name for an annual fee creates a much higher risk under both Order 2/2568 (at incorporation, the bank statement must show the Thai shareholder's own funds) and Order 1/2569 (at amendment, the managing partner or director must sign the Investment Confirmation Letter under criminal-penalty exposure).

Q2. Can a foreign authorized director change trigger DBD scrutiny even if foreign equity does not change?

A2. Yes. Order 1/2569 scenario (2) applies to amendments of a limited company's directors, number of signatory directors, or names of signatory directors that result in a foreigner becoming an authorized director able to bind the company alone or jointly. The triggering transaction is the director amendment, regardless of whether any share transfer occurs.

Q3. What evidence should support an Investment Confirmation Letter?

A3. The signing director or managing partner should be able to produce, among other documents: source-of-funds explanations for each Thai shareholder, bank statements covering the share-payment period, dividend records, board and shareholder meeting minutes, shareholder agreements, and any related-party agreements. The more the internal evidence package corroborates the confirmation, the lower the exposure if the structure is later reviewed.

Q4. Should a company using a questionable arrangement immediately file an amendment?

A4. Not before the evidence is reviewed. Once the Investment Confirmation Letter mechanism is triggered, the filing signatory makes a sworn statement tied to Foreign Business Act §36 and Thai Penal Code §§137 and 267. If historical funding and control documents do not support that statement, the filing itself may increase rather than reduce risk.

Q5. Should foreign investors consider BOI or FBL instead?

A5. Where the business facts support it, BOI promotion, a Foreign Business License, or another lawful approval route is usually more stable than a thinly capitalized Thai-majority structure. The correct route depends on business scope, capital structure, land or employment needs, and long-term exit planning.

Q6. Do the 2026 orders apply retroactively to existing companies?

A6. The orders apply prospectively to transactions filed on or after their effective dates — 1 January 2026 for Order 2/2568 (incorporation) and 1 April 2026 for Order 1/2569 (amendment). Existing Thai companies that do not initiate a covered incorporation or amendment are not directly triggered. However, any future amendment that introduces foreign equity, a foreign partner, or a foreign authorized director will engage Order 1/2569 and require an Investment Confirmation Letter at that time.

Q7. Are BOI-promoted companies subject to the Investment Confirmation Letter?

A7. The Investment Promotion Act §12 foreign shareholding exemption, where granted, removes the FBA equity cap for the promoted activity — foreign majority equity is not a legal defect. BOI-promoted companies are nonetheless Thai juristic entities filing with the DBD and therefore remain subject to the DBD's procedural documentation regime, including Order 2/2568 at incorporation and Order 1/2569 at amendment where the factual triggers are met. The legal question is not whether the documentation regime applies, but whether the Confirmation Letter can be truthfully signed given the BOI structure — which, for genuine BOI projects, it typically can.

Q8. Do the orders apply to partnerships as well as limited companies?

A8. Yes. Both orders expressly cover partnerships (ห้างหุ้นส่วน) and limited companies (บริษัทจำกัด). Order 2/2568 covers the incorporation of either form where foreign participation triggers the scope test. Order 1/2569 covers partnership amendments that change the Thai / foreign capital balance, and limited company amendments that add a foreign authorized director or signatory.

Lexcelsiam Note

This material is for general information only and does not create a lawyer-client relationship. The analysis is based on the full Thai text of DBD Central Partnership and Company Registration Office Orders No. 2/2568 and No. 1/2569, the attached Investment Confirmation Letter template, and the Thailand Foreign Business Act B.E. 2542 (1999) and Thai Penal Code. Whether a specific incorporation or amendment triggers documentary verification — and whether the signing applicant, managing partner, or director can support that documentation with verifiable evidence — depends on the company's funding history, share payment records, dividend flow, board and signatory arrangements, and the business's factual position under the Foreign Business Act. Where the outcome turns on source-of-funds reconstruction, director or signatory changes on a Thai-majority limited company, partnership amendment filings, or a conversion to BOI / FBL routing, a matter-specific legal review is required before the filing is lodged.
