Corporate Secretarial · Scenario S.9

Open a New Corporate Bank Account in Thailand

Thai banks require a board resolution drafted to their specific format — naming the bank, the account type, the authorised signatories, and the signing conditions. A generic resolution or an outdated affidavit will stall the application before it reaches a relationship manager. UnionSPACE reviews the specific bank's requirements, drafts the board resolution to the format the bank will accept, and assembles the complete certified document submission pack — delivered in 3–5 working days so the bank appointment can proceed without documentation gaps.

Get Started Talk to Us

Most Thai banks require a company affidavit issued within the last 3–6 months. Where the current affidavit is older than this — or does not reflect the current director and signatory position — a fresh affidavit must be obtained before the application is submitted. We check this at the outset and advise on whether a DBD update is needed before the bank appointment is booked.

Three Documentation Issues That Stall Thai Corporate Bank Account Applications

We check each of these before the submission pack is compiled

A Generic or Incorrectly Named Resolution

Thai banks require a board resolution that names the specific bank, the type of account, the authorised signatory or signatories by name, and the signing conditions. A resolution addressed to "any financial institution" or that does not specify the account type will be returned by the bank's compliance team. We draft the resolution to the specific bank's format requirements — based on the bank's checklist and, where needed, direct confirmation from the bank's corporate banking team.

An Outdated Affidavit

Most Thai banks require an affidavit issued within the preceding 3–6 months — some are stricter. An affidavit issued outside this window will be rejected even if the information on it is current. Where the current affidavit is too old, a fresh affidavit must be obtained from the DBD before the application is submitted. We check the affidavit issue date at the start and advise on whether a fresh one is needed before the bank appointment is booked.

Signatory Mismatch

The board resolution must name signatories whose authority is reflected on the current affidavit in exactly the terms stated in the resolution. A resolution naming a director as a sole signatory when the affidavit shows joint signature — or naming someone who is not on the current affidavit at all — will be rejected. Where the intended signatory or signing condition is not on the current affidavit, a signing authority change (Scenario S.3) must be filed before the bank application proceeds.

From bank requirement review to submission-ready pack — what happens at each stage

How We Prepare a Corporate Bank Account Opening Pack in Thailand

Bank Requirement Review & Document Check

We confirm the specific bank's document requirements — resolution format, certified copy requirements, affidavit age limit, and KYC checklist — and check the current affidavit against those requirements. We verify the signatory authority shown on the affidavit against the intended account signatories, and identify whether any prior DBD update is needed before the application can proceed.

Where the intended signatory is not shown on the current affidavit with the required authority, a signing authority change must be filed and a new affidavit obtained before the bank application. Attempting to open an account with a resolution that names a signatory not reflected on the current affidavit will result in the bank returning the entire documentation set.

Resolution Drafting & Execution

We draft the board resolution in the format required by the specific bank — naming the bank, the account type (current, savings, FCD, etc.), the authorised signatory or signatories by name and position exactly as shown on the affidavit, and the signing conditions. The resolution is sent for review before director execution is coordinated.

The signing conditions in the resolution must be stated in precisely the same terms as on the current affidavit. A resolution that describes signing authority differently from the affidavit — even in minor wording — gives the bank's compliance officer grounds to request clarification or return the documents. We cross-reference both documents before finalisation.

Certified Documents & Submission Pack Delivery

We prepare the certified true copy set of the affidavit, MOA, and other documents required by the bank, and compile the complete submission pack with a checklist of every item included. The pack is delivered digitally within the 3–5 working day window — ready for the bank appointment without further preparation required on the company's side.

The submission pack is the complete set the company takes to the bank. The bank's own processing — KYC review, compliance checks, and account approval — is entirely at the bank's discretion and timeline. Our responsibility is to ensure the documentation is correct and complete so the bank's review proceeds without documentation-related delays.

  • Drafting and signing coordination: 1–3 working days.
  • Pack delivery: within 3–5 working days from receipt of required information.
  • Bank processing: at the bank's discretion — outside this service.

Frequently Asked Questions — Corporate Bank Account Opening in Thailand

Answers to the questions we are asked most often

Thai banks typically require: a board resolution specifically authorising the account at this bank; a current company affidavit (most banks require one issued within 3–6 months); certified true copies of the affidavit and MOA; director and signatory ID documents; and for foreign directors, passport copies with current visa. Some banks require additional KYC materials, premises documents, or financial records. We review the specific bank's checklist before preparing the documentation.

Yes. A generic resolution is typically insufficient. The resolution must name the specific bank, the account type, the authorised signatory or signatories by name and position, and the signing conditions. A resolution that uses a general formulation such as "to open accounts at any bank" will usually be rejected by the compliance team. We draft the resolution to the specific bank's format requirements.

Most Thai banks require an affidavit issued within the preceding 3–6 months. Requirements vary — some banks are stricter. Where the current affidavit is older than the bank's limit, a fresh affidavit must be obtained from the DBD before the application is submitted. We check the issue date at the outset and advise on whether a new affidavit is needed before the appointment is booked.

A resolution naming a signatory whose authority is not reflected on the current affidavit will be rejected. The bank relies on the affidavit to verify the company's signing authority. If the intended signatory needs to be added — or the signing conditions need to change — a signing authority change (Scenario S.3) must be filed with the DBD and a new affidavit obtained before the bank application proceeds. We identify this at the document check stage.

No. This service covers the corporate secretarial documentation — the board resolution and certified document pack that the company presents to the bank. The bank's KYC review, compliance assessment, and account approval are at the bank's discretion and are entirely outside the scope of this service. UnionSPACE delivers correct and complete documentation; the bank makes its own determination on the application.

Yes. The service is bank-agnostic — we review the requirements of the specific bank named by the client and tailor the resolution and document set accordingly. Different banks have different resolution formats and certified copy requirements. Where we need to confirm the specific bank's requirements, we contact the bank's corporate banking team before preparing the documents.

A Generic Resolution Will Be Returned — A Bank-Specific One Won't

Thai banks require a resolution naming the specific bank, the account type, the signatories, and the signing conditions — and an affidavit that matches. A generic resolution or a stale affidavit sends the application back to the start. We review the bank's requirements first and draft the documentation to the format that gets accepted.
