Opening a Foreign Bank Account for a Thai Company: Corporate Documents That Survived Compliance Review
6 min read · Updated 2026-08-12
In short
A Thai company's affidavit and shareholder list were rejected twice by an overseas bank's compliance team. The issue was document age and the certification chain, not content.
The situation
A Thai limited company expanding into Singapore needed to open a corporate account. Its accountant sent scanned copies of the company affidavit, shareholder list, memorandum of association and a director's passport.
Why the file stalled
Bank compliance teams work to their own document standard: recently issued originals, an unbroken certification chain to an authority they can verify, and a translation they can rely on. Scans and year-old extracts fail that standard regardless of how accurate they are.
Documents in the bundle
- Company affidavit (Nangsue Rabrong) issued within the bank's freshness window
- Shareholder list (Bor Or Jor 5)
- Memorandum of association and, where requested, the articles
- Board resolution authorising the account opening and naming signatories
- Passports and address evidence for directors and beneficial owners
How it was sequenced
1. Ask the bank for its documentary standard in writing
Freshness window, whether apostille or consular legalisation is required, and whether certified English translations must be bound with the Thai originals. Guessing here costs a full cycle.
2. Reissue the corporate extracts rather than recertify old ones
Affidavit and shareholder list were pulled fresh from the Department of Business Development so the issue date sat comfortably inside the window with room for the certification steps that follow.
3. Translate and certify in the right order
Thai originals first, then certified English translation, then the authentication layer covering both — reversing this leaves the translation outside the certified set.
4. Apply the correct authentication for the destination
The chain was selected against the destination's status and the bank's stated requirement, then run once for the complete bound set rather than piecemeal per document.
5. Draft the board resolution to mirror the bank's mandate form
Signatory names, spellings and authority limits were written to match the bank's own mandate wording, which is what the compliance reviewer compares against.
Pitfalls to avoid
- Submitting extracts issued months earlier — many banks treat corporate documents as stale after a short window.
- Certifying the Thai original and translating afterwards, leaving the translation uncovered by the certification.
- Name mismatches between the passport, the shareholder list and the resolution.
- Sending scans when the reviewer's checklist says originals or certified copies.
The advisory call
The recurring lesson in cross-border corporate files is that the sequence is the deliverable. We build a dated plan backwards from the bank's freshness window so that reissue, translation and authentication all land inside it, and we tell clients plainly when a document should not be ordered yet.
Where the file landed
The rebuilt bundle cleared compliance on first submission, and the same certified set was reused for the company's subsequent registration filings.
Frequently asked questions
How recent must a Thai company affidavit be?
It depends on the receiving institution; banks commonly work to a short window measured in weeks rather than months. Ask before ordering, because the certification steps that follow consume part of that window.
Should the translation be certified before or after legalisation?
Translate and certify first, then run the authentication over the combined set, so the certified translation is inside the chain. Doing it the other way round often means repeating the authentication step.
Can one certified set be reused for several institutions?
Often yes, if the freshness window still holds and each institution accepts certified copies. We usually prepare additional certified copies at the same time, which is far cheaper in time than repeating the chain later.
Is this a real client file?
No. Every case on this page is a composite written from recurring patterns in our practice, with all identifying detail removed. It is published to show how a file is sequenced, not to promise the same result — requirements change by authority, destination and document type.
Can you run the whole chain for me instead?
Yes, and that is what most clients ask for. Send a photo of what you already hold, the destination country and the receiving authority to LINE @Thainotary or call 094-895-8999. We map the correct chain first, tell you what is missing, and then handle the certification, translation and submission steps end to end.
Would you rather we handled it?
Our practitioners map the chain before anything is filed, deal with the authorities and report at each stage. Call 094-895-8999 or message LINE @Thainotary.
