Sole Director Dies: How a Thai Company Keeps Paying, Signing and Operating

The core answer

When the only director of a Thai limited company dies, the company does not die with them. It remains a legal person, its contracts and employees continue, and its tax filings stay due. What ends is the person's position as director. The shares they owned are a different thing: they belong to the estate and go to the heirs.

The result is a gap. The company affidavit still names the dead person as the only one who can sign. Until a new director is appointed, nobody can lawfully sign for the company, and the bank is likely to freeze the account.

The rule (Civil and Commercial Code, Department of Business Development). Only the general meeting of shareholders may appoint or remove a director (section 1151). Death is a recognised ground for leaving office in the Department of Business Development's own guide. The change must be registered within 14 days.

Our practical view. The legal hard part is not the paperwork. It is that the Code's route for shareholders to call a meeting assumes there is a director to ask. When there is none, we would speak to the registrar early, and be ready to ask the court for a temporary representative if the registrar and the shareholders cannot agree a clean route.

1. Does the company stop when its only director dies?

No. A company is separate from its directors. Employment contracts, supplier contracts, leases, licences and tax duties are the company's, not the director's. Death does not dissolve it.

Two things must be kept apart:

If the deceased was the sole director and the main shareholder, the family often thinks "the company is ours now". Legally, the heirs own the shares, but they do not become directors until the meeting appoints them.

2. Who can sign for the company right now?

Start with the company affidavit (หนังสือรับรอง) issued by the Department of Business Development. It states who the directors are and which of them can bind the company. If the affidavit says "Mr A signs alone" and Mr A has died, then no person named there can sign.

Practical consequences:

• Do not let a relative or manager sign as if they were a director. Without authority, the document may not bind the company, and the signer risks personal exposure.
• Powers of attorney granted by the dead director are doubtful. Whether a power the director granted on the company's behalf survives their death can be disputed. We would not rely on one for important payments or contracts without advice.
• Other registered authority. If the company had registered a second person with signing power, or a manager with authority recorded in the articles, that person is the first thing to check.
• Notify counterparties in a measured way. Tell key customers and suppliers that the company continues and a new director is being appointed.

3. What happens to the bank account, payroll and payments?

This is mostly bank practice rather than a statute, so it varies by bank. In general, once a bank learns that the sole signatory has died, it will stop that person's mandate. The company then cannot withdraw, pay salary or pay suppliers until a person with registered authority is in place.

What to do in the gap:

1. Ask the bank in advance what it requires: the death certificate, a new affidavit, a board or shareholders' resolution, and new signatory forms.
2. Pay the essentials first: salaries, social security contributions, rent, utilities and tax. Use any other authorised signatory or a pre-agreed arrangement, and keep a record of every payment and why.
3. Do not use the deceased's personal accounts or cards for company money. That mixes the estate with the company and creates problems for both.
4. Tell employees plainly that their employment continues. The employer is the company, and the director's death does not end employment contracts.
5. Keep tax filings moving. Monthly withholding tax, VAT and social security returns remain due. Ask your accountant who can file, and what the Revenue Department or Social Security Office needs about the change of authorised person. Check current requirements with them.

4. Who appoints the new director when none is left?

The Code is clear about who decides: only the general meeting of shareholders can appoint a director (section 1151). The difficulty is how the meeting is called.

The Code says:

• Directors call extraordinary meetings (section 1172).
• Shareholders holding at least one-fifth of the shares can request a meeting in writing, stating the purpose (section 1173).
• If the directors do not call it within 30 days of the request, those shareholders may call it themselves (section 1174).

That ladder starts with a director who can receive the request. With no director, the ladder has no first step.

What the Department of Business Development says (as reported). A 2022 Thammasat University law thesis records the Department's reply to a question about a company whose only director died. As reported there, the Department's view is that shareholders cannot simply call a meeting themselves, and that the route is a court application under section 73 of the Code. That section allows the court, on the request of an interested person or the public prosecutor, to appoint a temporary representative where a position among a juristic person's representatives is vacant and leaving it empty is likely to cause damage. The same writing notes that Supreme Court decisions have applied section 73 to companies, and it criticises the route as slow.

We have not seen a current written notice from the Department. Treat this as a strong signal, not a settled rule.

Other routes to check.

• The articles of association. Some companies' articles say who may call a meeting or fill a vacancy. Read yours before anything else.
• Unanimous written agreement. If every shareholder, including the heirs, agrees on a new director and the registrar accepts the paperwork, the practical risk falls. Ask the registrar's office first which documents they will take.
• Court application. If shareholders disagree, or the registrar will not proceed, a section 73 application gives a result nobody can later call irregular. The temporary representative can then call the meeting to elect permanent directors.

Our practical view. Small family companies with cooperative shareholders should phone the registrar (DBD hotline 1570 or the provincial commerce office) before they hold any meeting. Where there is a dispute among heirs, or a bank or a large customer is waiting, go to the court route sooner rather than later.

5. Who votes the dead director's shares?

The shares belong to the estate. Until they are transferred, the share register still shows the deceased as shareholder. Someone has to manage them.

• If there is an estate administrator (named in a will or appointed by the court), the administrator generally manages estate property. Our guide on how to appoint and use an estate administrator covers that process, so we do not repeat it here.
• If the court is asked to appoint one (section 1713 allows an heir, an interested person or the public prosecutor to apply), the order is what the company and registrar will rely on.
• If there is a will, it may direct how the shares pass. See the foreign will and inheritance guide.

Whether the administrator may vote the shares before the estate is divided is a point to settle with a lawyer for the particular estate. The administrator also owes duties to all heirs, so one heir's wish to "take control" of the company does not decide the question.

Once shares pass to heirs, the share register and the annual shareholder list filed with the registrar will need updating.

6. What must be registered, and by when?

According to the Department of Business Development's guide on changing directors:

• A change of directors must be filed with the registrar within 14 days of the change.
• Filing is made at the Department's office, the provincial commerce office, or through e-registration, depending on where the head office is.
• The documents include forms บอจ.1 and บอจ.4, the details form for each new director, copies of ID, and, where a director has died, a copy of the death certificate.
• The guide says the filing is made by a director with authority as originally registered. That is impossible here, so ask the registrar who may sign once a temporary or new director exists. Do not assume.
• If the signing powers also change, the shareholders' resolution should say so, and the new powers must be registered at the same time.
• Businesses under special laws may need approval from their regulator before a new director is appointed.

Check fees and forms on the Department's website at dbd.go.th before filing, because they change. Our guide on company changes after registration explains the general filing process.

7. How do I protect the company in the meantime?

A short list of safe steps while the appointment is arranged:

1. Gather documents: the latest affidavit, articles, share register, last shareholder list, bank mandate forms.
2. Agree one point of contact among the shareholders and heirs.
3. Tell the accountant and keep tax and social security deadlines in a calendar.
4. Preserve value: no asset sales, no new long contracts, no large payments outside the ordinary course until a director is registered.
5. Keep a log of everything done on the company's behalf during the gap, with reasons.
6. Get advice early if the heirs disagree. Delays harm the company and every heir's share.

8. Planning ahead: single-director companies

A one-director company is simple to run and fragile in a crisis. Cheap measures:

1. Appoint a second director, even a trusted family member or senior manager, and set the signing powers so either can sign up to a sensible limit.
2. Write the articles to handle a vacancy, for example by saying how a meeting may be called if no director remains. Take advice on the wording.
3. Make a will that deals with the shares and names an estate administrator who understands the business. The inheritance guide explains the role.
4. Have a shareholders' agreement that sets who steps in as director and how the family and any co-owners decide.
5. Set up the bank mandate with at least two possible signatories and a clear approval limit.
6. Keep a continuity file: affidavit, articles, passwords, key contracts, accountant and lawyer contacts.
7. Review the set-up once a year or when the business grows.

Checklist: first two weeks

1. Get the death certificate and copies of the company affidavit, articles, share register and bank mandate.
2. Check who, if anyone, still has registered signing authority.
3. Tell the bank, the accountant and key staff, and ask the bank what it needs.
4. Keep paying wages, social security and tax from whatever authorised route exists.
5. Read the articles on calling meetings and filling vacancies.
6. Phone the registrar about the route for appointing a new director.
7. If shareholders cannot agree, or the registrar requires it, prepare a court application for a temporary representative.
8. Appoint the director by shareholders' resolution and file within 14 days of the change.
9. Update bank signatories, tax and social security records and the affidavit held by counterparties.
10. Deal with the estate: estate administrator, transfer of shares, updated share register.
