Why registered particulars matter
A Thai company's registered particulars — directors, signing arrangement, capital, head office, objectives — are what everyone outside the company relies on. Banks check them. Counterparties check them. Authorities check them. The company affidavit is simply a certified extract of them.
When the reality inside the company changes and the registration does not, the gap shows up at the worst moment: a bank transaction, a contract signing, a tender or an inspection. See who can bind your Thai company.
1. The common changes
| Change | Usually needs | Registration |
|---|---|---|
| Appoint or remove directors | Shareholders' meeting resolution | Within 14 days of the change |
| Change signing arrangement | As the articles provide | Register the new arrangement |
| Increase capital | Special resolution | Register the resolution within 14 days, then the increase |
| Reduce capital | Special resolution + creditor notice and objection period | After the creditor process |
| Change objectives | Special resolution to amend the memorandum | Register the amendment |
| Change company name | Special resolution | Register the amendment |
| Move head office | Depends on whether the province in the memorandum changes | Register the new address |
| Shareholder changes | Share transfer formalities and register update | Reflected in the shareholder list |
2. Meetings and resolutions
Changes that need a shareholders' resolution depend on a properly called meeting:
- Notice given in the form and period the law and articles require
- Agenda items stated in the notice
- Quorum and voting thresholds met
A resolution passed at an irregular meeting can be challenged by a shareholder within one month. See minority shareholder rights.
3. Capital increases
- A capital increase needs a special resolution
- New shares must generally be offered first to existing shareholders in proportion to their holdings
- Register the resolution within fourteen days, and register the increase for the shares actually issued
- Check the effect on foreign ownership — an increase can shift the ratio. See whether your Thai company needs a foreign business licence
4. Capital reductions
A reduction protects creditors: they must be notified and given the opportunity to object before the reduction is registered. Plan for that period; a reduction is not a quick filing.
5. Directors resigning or leaving
- A director may resign by notice to the company; the resignation takes effect when the company receives it
- The company must register the change
- A resigning director can also notify the registrar, which matters when the company does not act
- If the company's signing arrangement depended on that director, update it at the same time — otherwise no one may be able to sign
6. Moving the head office
Whether a move is a simple address change or an amendment to the memorandum depends on whether the province stated in the memorandum changes. Either way, the new address must be registered, and the knock-on updates below apply. See your Thai company's registered address.
7. Knock-on updates companies forget
After registration, update:
- Bank mandates and authorised signatories
- Revenue Department records, including VAT registration details
- Social security records
- Investment promotion records, where the company holds promotion
- Licences that name the company's address or directors
- Work permits of foreign directors or employees affected by an address or role change
- Counterparties, who hold old copies of the affidavit
8. Annual filings
Some information is refreshed every year rather than when it changes, such as the list of shareholders filed after the annual meeting. See the annual corporate filing calendar.
Checklist for any change
- Identify whether a shareholders' resolution is needed, and of what kind
- Call the meeting correctly, with the item on the agenda
- Prepare filing documents and register within the deadline
- Update the signing arrangement if directors change
- Check foreign ownership effects of capital or shareholder changes
- Make the knock-on updates listed above
- Obtain a fresh affidavit and circulate it where needed
