A change of director or signing authority in a Thai limited company takes effect towards third parties once the change is registered with the Department of Business Development. The usual sequence is: hold the meeting and pass the resolution required by the articles and Book III of the Civil and Commercial Code; prepare the change application with supporting documents; file it with the registrar; then obtain a fresh company affidavit. Where the director is a foreign national, identity documents or powers of attorney signed abroad must be legalised in the country of signing and their translations certified before filing in Thailand.

Appointing or removing a director requires a shareholders’ resolution under the articles of association, followed by an amendment filing with the Department of Business Development within the legal period from the resolution date. The change takes effect against third parties once registered.
If the new director is a foreign national abroad, prepare a certified passport copy, and the signature used must match the one that will be used going forward. Changing an authorised director also has to be reported to the bank and may affect the outgoing director’s work permit.
Check the articles of association for the signing authority of directors, such as single or joint signatures, and confirm the incoming director is legally qualified, not prohibited and not bankrupt. If the new director will bind the company with the bank, notify the bank in advance to prepare the account changes.
Beyond the Department of Business Development filing, a director change may need to be reported to other agencies the company is registered with, such as the Revenue Department, the Social Security Office and any specialised licensing bodies.
Directors of a limited company are appointed or removed by shareholder resolution under the Civil and Commercial Code, unless the articles provide otherwise, for example by letting the board fill a vacancy. Read the articles before calling a meeting, and send the notice in the manner and within the period the law and articles require.
The Department of Business Development requires the director change to be registered within a set period from the resolution, generally 14 days according to its published guidance. Late filing can attract a fine; check the current deadline with the Department before filing.
If an authorised signatory changes, update the bank, the Revenue Department and any licensing agencies after registration. Otherwise documents signed by the new director may be refused.
A foreign director provides a passport copy, and where documents are signed outside Thailand the signature usually needs notarisation and the required certification before use. Having a foreign director does not change shareholding, but if control or shareholders change at the same time, check the effect on status under the Foreign Business Act.
Being a director does not by itself confer the right to work in Thailand. A foreign director working in Thailand needs an appropriate visa and work permit under the law on management of foreign workers.
Documents commonly include the amendment application, copies of the meeting notice and proof of delivery, minutes containing the resolution, ID or passport copies of new directors, the outgoing director’s resignation letter where relevant, and a power of attorney if someone files on the company’s behalf. The Department of Business Development now accepts filings through its electronic registration system.
Frequent reasons for rejection: notice dates that do not meet the period set by law or the articles, a post-change number of directors that conflicts with the articles, director signatures that differ from those on file, and changes to signing authority without clearly worded new authority.
A director who resigns does so legally once the letter reaches the company, but the name stays on the company affidavit until registration. Resigning directors should follow up on the filing and keep proof that the letter was delivered.
After registration, obtain a new company affidavit and check that director names and the signing-authority wording match the resolution exactly. Report errors promptly, because banks and agencies rely on the affidavit to confirm authorised signatories.
Companies holding specific licences, such as a Foreign Business Licence, a BOI certificate or a regulator’s licence, should check whether the director change must also be notified to that agency, since each has its own rules.
Where the former director signed work permit documents for foreign staff, check that future filings are signed by the new board so renewals are not disrupted.
We review the articles, draft the meeting notice and minutes, prepare the application, coordinate signature certification if a director is abroad, file the registration and check the new affidavit. We then give the company a list of agencies that should receive the updated director details.
