Change Your Thai Company Name — Name Reservation to Updated Affidavit
A company name change in Thailand is not a simple administrative update — it amends the Memorandum of Association, requires a special shareholder resolution with a three-quarters majority, and has no legal effect externally until the DBD registration is complete and the updated affidavit is issued. Using the new name before that point creates legal uncertainty over the identity of the contracting party on every document executed during the gap. UnionSPACE manages the full process — name reservation, resolution, MOA amendment, DBD filing, and updated affidavit — in 10–15 working days.
Why a Company Name Change Requires More Than a Decision — and Why Sequence Matters
A company name change amends Clause 1 of the Memorandum of Association — the company's foundational constitutional document. It requires a special resolution passed by a three-quarters majority of shareholders at a properly convened meeting, an MOA amendment filed with and registered by the DBD, and an updated company affidavit issued in the new name. Each step is a prerequisite for the next.
Until the DBD registration is complete, the company's legal name for all external purposes — contracts, invoices, bank accounts, tax filings, and government submissions — remains the old name. A company that begins using the new name on correspondence, invoices, or agreements before the affidavit is updated is signing documents in a name that has no legal standing. Counterparties, banks, and the Revenue Department will rely on the affidavit, not the company's preference.
UnionSPACE checks name availability, reserves the proposed name with the DBD before any documentation is prepared, and manages the full process from resolution through to updated affidavit delivery — within 10–15 working days. A downstream notification checklist is provided so the name change is reflected consistently across the company's regulatory and commercial records.

Three Things to Confirm Before Changing Your Company Name
We verify each of these before any document is prepared or any name is reserved
Name Availability
The proposed name must be available on the DBD register, must not be confusingly similar to an existing registered name, and must comply with DBD naming guidelines — including restrictions on words implying government affiliation, regulated status, or prohibited concepts. We check availability and compliance before reserving, so no documentation is prepared for a name that cannot be registered.
Shareholder Approval
A company name change requires a special resolution — not an ordinary resolution and not a board resolution. The resolution must be passed by a three-quarters majority at a meeting at which at least half of the total shares are represented. If the company's shareholder structure makes this threshold difficult to assemble, we advise on the most practical approach before the process begins, not after a meeting fails to reach quorum.
Downstream Updates
The updated affidavit is the starting point — not the end point — of a name change. The Revenue Department, banks, the Social Security Office, and counterparties to material contracts must each be separately notified and their records updated. Failing to do so creates a mismatch between the legal name and the operational name that creates friction at every subsequent interaction. We provide a downstream notification checklist at the point of affidavit delivery.
From name availability check to updated affidavit — what happens at each stage
How We Handle a Company Name Change in Thailand
Name Availability Check & DBD Reservation
We check the proposed name — in both Thai and English where applicable — against the DBD register and naming guidelines. This includes a similarity check against existing registered names, a review for prohibited words or regulated-sector implications, and confirmation of the correct Thai transliteration where an English name is also being registered. Once the name passes all checks, we reserve it with the DBD before any documentation is prepared.
Reservation before drafting is essential. A name reserved while documentation is being prepared cannot be claimed by another company in the interim. A name checked but not reserved can be taken at any point — leaving the shareholder resolution and MOA amendment prepared for a name that is no longer available. We reserve first, then draft.
Information & Document Verification
We collect the current company affidavit, MOA, and shareholder register to establish the existing position and confirm the quorum and majority required for the special resolution. We confirm the effective date of the name change and verify that the company's shareholder structure can support the three-quarters special resolution threshold before the meeting is convened.
Where the shareholding structure makes the three-quarters threshold difficult to achieve — for example, in companies with a minority shareholder who may not cooperate — we advise on the options before the documentation is prepared. A special resolution that fails to pass at the meeting wastes the name reservation window and requires the entire process to begin again.
Shareholder Resolution & MOA Amendment Drafting
We draft the special shareholder resolution approving the name change and the amended Clause 1 of the Memorandum of Association reflecting the new name. Both documents are sent to you for review before finalisation and execution is coordinated with the shareholders. The resolution must match the reserved name exactly — any discrepancy between the reserved name, the resolution, and the MOA will cause the DBD to reject the filing.
The MOA amendment must reflect the new name in precisely the same form as the DBD reservation confirmation. Names with unusual capitalisation, punctuation, or abbreviations must be reproduced character-for-character. We verify consistency across all documents before any are sent for signature.
DBD Filing & Updated Affidavit Delivery
We submit the complete filing package — executed resolution, amended MOA, and supporting documents — to the DBD within the name reservation window, manage all officer liaison, and collect the updated company affidavit once the filing is accepted. The updated affidavit reflecting the new company name is delivered digitally on the day of issuance — this is the operative document for all external purposes from that date.
At delivery, we provide a downstream notification checklist covering the Revenue Department, banks, the Social Security Office, and material contract counterparties. The legal name change is complete on affidavit issuance; the operational name change is complete only when each of these records has been updated.
- Drafting and signing coordination: 3–6 working days from receipt of required information.
- DBD processing and affidavit issuance: 5–9 working days.
- Total end-to-end: 10–15 working days.
Frequently Asked Questions — Company Name Changes in Thailand
Answers to the questions we are asked most often
A Thai company name change requires: name availability check and DBD reservation; a special shareholder resolution approved by a three-quarters majority; amendment of the Memorandum of Association reflecting the new name; DBD filing of the amended MOA and supporting documents; and issuance of an updated company affidavit. The new name has no legal effect externally until the DBD filing is registered and the updated affidavit is issued.
No — not for external legal purposes. Until the DBD registration is complete and the updated affidavit is issued, the old name remains the company's legal name. Contracts, invoices, bank documents, and government submissions must continue to use the old name. Using the new name before registration creates uncertainty over the legal identity of the contracting party on every document executed in the interim. The affidavit is the authoritative document third parties rely upon.
A special resolution is required — not an ordinary resolution and not a board resolution. The resolution must be passed by a three-quarters majority of votes cast at a meeting at which at least half of the total issued shares are represented. This is a higher threshold than a routine AGM resolution and must be correctly identified and met before the MOA amendment can be filed with the DBD.
The updated affidavit is the starting point, not the end point. Once issued, the company must notify and update: the Revenue Department (VAT and tax registration records); all banks (account names and mandates); the Social Security Office; any business licences or permits held in the company name; and counterparties to material contracts. Failing to update these records promptly creates a mismatch between the legal name and the operational record that causes friction at every subsequent interaction. We provide a downstream notification checklist at the point of affidavit delivery.
Yes. Thai limited companies may register both a Thai name and an English name with the DBD. Both must comply with DBD naming requirements and be reserved before filing. Where the company currently has only a Thai name and wishes to add or change an English name, or vice versa, both are handled within the same MOA amendment process. We check availability for both language versions and manage reservation and registration concurrently.
Yes — where other MOA amendments are required at the same time (such as a change of objectives or authorised capital), both can be addressed within a single shareholder resolution and a single DBD filing. This is more efficient and cost-effective than separate filings. Contact us with details of all intended amendments and we will advise on the most appropriate approach and provide an adjusted quote.
