Changes that must be registered
Changes in directors, signing authority, office, objectives, registered capital and articles must be filed with the Registrar within deadlines from the resolution date. Check each item's deadline.
Changes to directors, capital, address or objectives need valid resolutions and registration with the Department of Business Development within deadlines; share transfers in a private company are recorded in the share register, with stamp duty and alien-status checks.
Each change uses a different resolution type and document set. Late filing or defective resolutions can make the change ineffective or attract fines. This page checks the items before documents are prepared.

| Change | Directors, capital, address, objectives, shareholders | What must be registered and deadlines |

Changes in directors, signing authority, office, objectives, registered capital and articles must be filed with the Registrar within deadlines from the resolution date. Check each item's deadline.
Capital increases or reductions and changes to objectives or articles require a shareholders' special resolution. Notices must follow the articles and law; defective meetings can be challenged.
Private company share transfers are made in writing, signed by transferor and transferee with a witness, and entered in the share register. Check transfer restrictions in the articles and file shareholder lists as required.
Share transfer instruments attract stamp duty under the Revenue Code and the seller may owe tax on gains. Confirm the valuation basis with the Revenue Department.
Adding foreign shareholders can change the company's alien status and affect licences or BOI rights. Review before signing transfers.
Directors or shareholders abroad may need to sign before a notary or certify documents, with Thai translation acceptable to the Registrar. Allow time for this.
General preparation guidance. Check current announcements and project facts before filing; eligibility and approval are not assured.
