Every company incorporated in India must have a registered office address. It's a top place of business. All sanctioned correspondence from the Registrar is transferred to this office. For any reason, you may have to shift your top place of business be it within the city, within a state, or in a different city or in a different state altogether an inauguration to ROC is a must-have. The listed office of a company is that to which sanctioned correspondence and all formal legal notices addressed to the company will be transferred.
The registered office of the Company will also determine the domicile of the company (State of Incorporation). The state or location in which the registered office of the Company is situated will determine the Registrar of Company (ROC) to which the application for company registration must be made. Any change of address of Registered Office must be notified to the Registrar of Company (ROC) within 15 days.
