Changing a company’s registered office involves relocating its official address as recorded in the memorandum of association. To effect this change, the company must pass a board resolution and, if required, a special resolution by shareholders. The company must then file Form INC-22 with the Registrar of Companies (ROC) within 30 days of the change, providing the new address and proof of the new location, such as a utility bill or lease agreement. Updating the registered office ensures that all legal documents, communications, and official correspondence are directed to the correct location, maintaining accurate and compliant corporate records.
