Who Should Sign for Your Thai Company? A Founder's Checklist

Before registering a Thai limited company, agree who may sign for it, whether signatures must be joint and whether the company seal is required. DBD's incorporation guide asks for the names or number of directors authorised to bind the company. Settle this before preparing the application. DBD incorporation guide, required information item 11 (Thai)

Does every director have authority to sign?

Check the company's signing provision. DBD lists director details separately from the names or number of authorised directors. Ask your filing advisor to show you the proposed wording before submission. DBD establishment guide, required information items 3–4 (Thai)

Must a company seal always be used?

DBD says a company can choose not to register a seal if the directors' signing authority does not require it. Decide on the signing provision and seal together. DBD incorporation guide, item 14 (Thai)

A discussion checklist for co-founders

The following is practical preparation advice. List who handles customer contracts, purchasing and bank paperwork. Consider how often proposed signatories are available together and who would hold the seal if you choose to use one.

For example, suppose two founders work in different provinces and are considering joint signatures. Plan document delivery and approvals before choosing the application wording. This hypothetical example helps you consider the operational consequences.

What should you send to an accounting firm?

Provide your business activity, number of directors and proposed signing arrangement. Say whether you need pre-incorporation advice only or also registration and monthly accounting. Ask for those scopes to be separated in the quotation.
