A company can alter its AOA. A company can do so by passing a special resolution, within the purview of MOA by following the provisions of Companies Act. The changes made in articles should not be contrary to any law or company’s act. If by making a provision in AOA changes in AOA are restricted, then such provision will be void. Hence, changes in AOA must be legal and in the interest of the company. Changes are made effective only when they are registered with BOC.
