Documents Required to Register a Company in Thailand

As at September 4, 2026, a Thai private limited company formation file is a reconciled digital record: promoter and subscriber identities, the memorandum of association, statutory-meeting decisions, directors and binding-signature authority, registered-office details, share-payment evidence, and the Department of Business Development (DBD) application set. New formations have been online-only through DBD Biz Regist since July 1, 2026.

A document pack is ready only when every name, share, baht amount, date and signature authority reconciles. Foreign participation, an overseas corporate shareholder, capital above THB 5 million, or a flagged head-office address can add evidence; those conditions should be tested before anyone signs.

Key takeaways

• DBD Biz Regist is the mandatory filing channel for a new Thai limited company; paper walk-in formation ended nationwide on July 1, 2026.
• Promoters, subscribers, shareholders and directors are different legal roles even when the same individuals occupy several of them.
• The memorandum, subscription totals, meeting approvals, paid amounts, shareholder list and director authority must tell one consistent story.
• Order 2/2569, effective August 1, 2026, adds a prescribed investment explanation and matched bank trails in two foreign-involvement scenarios.
• Foreign business permission, tax registration, bank onboarding, immigration and sector licensing are separate packs, not substitutes for DBD formation evidence.

Build the universal DBD formation file

The first source record is the accepted company name and memorandum of association (MoA). Under the amended Civil and Commercial Code, at least two promoters sign the MoA. Record the intended name, registered-office province, objectives, registered capital, number and value of shares, and each promoter’s identity and subscribed share. Use names exactly as shown on Thai identification or passports. The Royal Gazette amendment is the primary source for the two-person rule.

Before registration, all shares must be subscribed. The statutory meeting then adopts any articles of association, ratifies promoters’ contracts and expenses, addresses any preferential shares, appoints the first directors and auditor, and fixes their authority or remuneration as applicable. The directors call the agreed share payment, which cannot be less than 25% of each share’s value, and retain a subscriber schedule and receipts that match the amount reported to DBD. The formation application must be lodged within three months after the statutory meeting.

Translate the decisions into the filing set

The current DBD forms portal publishes Bor.Or.Jor.1, the limited-company registration certification sheet, Bor.Or.Jor.2 for the MoA, Bor.Or.Jor.3 for registration particulars, Form Kor for directors, Form Wor for objectives, Bor.Or.Jor.5 for shareholders and conditional attachments. In DBD Biz Regist, some items are entered as structured data or generated electronically rather than uploaded as a preprinted page. Follow the live task list without changing the underlying legal facts.

Add each relevant signer’s identity evidence, the director’s binding-signature wording, the full head-office address and location map, and a power of attorney only if a representative is appointed. Since July 1, 2026, the Ministry of Commerce implementation notice confirms that new formations are filed through DBD Biz Regist, where identity checks, signatures, status review, payment and registered e-documents form one digital workflow.

Control each document by owner and stage

A checklist says what exists; a control map says who can correct it. Freeze a master spelling sheet and capitalization table first, then assign every record below to its source owner. “Universal” means normally required for every private-company formation. “Conditional” means add it only when the stated fact or registrar check applies.

The fastest recovery is upstream: correct the identity, capitalization or authority source first, then regenerate every dependent form. Patching Bor.Or.Jor.5 alone does not cure a conflicting subscription schedule, payment receipt or meeting minute.

Apply conditional evidence before signing

Central Partnership and Company Registration Office Order 2/2569 took effect on August 1, 2026 and replaced Orders 2/2568 and 1/2569. For a new company, it applies where foreign shareholders hold less than 50% of registered capital , or where there is no foreign shareholder but a foreign director can bind the company alone or jointly with another director. The official Gazette order controls; the Ministry’s implementation note confirms its effective date and consolidation of the earlier measures.

Reconcile both sides of the 2026 bank trail

When either trigger applies, the applicant adds the Order’s prescribed investment-explanation letter and bank-issued statements for the relevant accounts. Each Thai shareholder’s statement must cover the three months before the stated share-payment date and show a withdrawal or transfer consistent with that person’s contribution. The designated director’s receiving-account statement must show corresponding credits from every shareholder, with the amount and date matching the explanation. The applicant signs the explanation and applies the company seal if one is used.

This is an evidence-of-funds test, not a general foreign-ownership approval. A company at or above 50% foreign ownership falls outside this particular formation trigger but may be a “foreigner” for Foreign Business Act purposes. Keep the identities, authority instruments and source documents for an overseas investor aligned with the practical foreign shareholder identity and authority file , while treating any Foreign Business License or Certificate analysis separately.

Prove foreign identity and corporate authority

For a foreign individual, use the passport or other identity evidence accepted by DBD, match the romanized name across every record, and complete the identity/signature route offered for that filer. If an overseas corporation will subscribe for shares, prepare a current home-register extract or comparable evidence of existence, its constitutional or board authority for the investment, the named human signatory’s ID, and a power of attorney if a delegate acts. A Thai translation certified for accuracy may be needed when supporting content is not in Thai.

Do not impose one blanket legalization formula. DBD’s official signature guidance recognizes overseas execution before a competent Thai diplomatic, consular or commerce official; certification by a person authorized under local law; or attestation by two reliable persons whose signatures are verified before the registrar. Certification follows the document and signing route. Confirm the route before ordering notarization, consular legalization or translations.

Two other checks remain conditional. A formation with registered capital above THB 5 million requires the payment-confirmation and bank or asset evidence prescribed by Order 1/2567, reflected on the current DBD forms portal. A head office caught by Order 4/2568’s enhanced address review needs the relevant premises owner’s consent and evidence of the right to use the address. Do not request either pack merely because it appears on a generic checklist.

Keep formation and operating packs separate

DBD registration creates the legal entity; it does not grant every operating permission. Use the formation record as the entity layer within broader Thailand business formation requirements , then open separate workstreams only when the facts require them.

• Foreign Business License (FBL), Foreign Business Certificate (FBC) or Thailand Board of Investment (BOI) papers establish a foreign-business route; they do not replace the MoA, meeting record or DBD application.
• Revenue Department tax and VAT filings use the registered company’s resulting records and their own premises or business evidence.
• A bank’s corporate know-your-customer pack is institution-specific and follows incorporation; DBD’s share-payment evidence does not guarantee account approval.
• Visa and work-permit documents concern the foreign worker, sponsoring company, role and employment conditions, not whether the company was validly formed.
• Sector licenses add regulator-specific technical, capital, premises or personnel evidence after the proposed activity is classified.

Keeping these packs separate makes rejection diagnosis faster. A DBD query about an unmatched shareholder payment is repaired in the formation file; a restriction on the intended activity is resolved in the foreign-business or sector-permission workstream.

Test whether the registration file is ready

Proceed when the DBD Biz Regist task list is complete; every person and corporation has an identity-to-authority chain; MoA, subscription, meeting, director, shareholder and payment figures reconcile; address evidence is sufficient; and each applicable conditional order has a named attachment. Stop before signature if funds move from an unexplained account, corporate authority ends before the human signer, or the proposed activity still lacks a viable foreign-business route.

Submission is not completion. Close the formation file only after the registrar accepts it, the fee is paid, and the electronic registration certificate, company affidavit and registered particulars are available for download. Preserve the accepted application, payment evidence, registrar messages and final e-records as the source pack for tax, banking and licensing work.
