Registered office requirement ensures companies maintain a capable address for communications, with registrar verification and penalties for default. Companies must maintain a registered office capable of receiving communications and verify it to the Registrar within the prescribed period. The company must display its name and registered office at business premises, include corporate identity and contact details on stationery and specified documents, and, where applicable, show former names and One Person Company status. Changes to the registered office require notice to the Registrar and, except by special resolution, cannot move outside the local limits; intra state jurisdictional changes require Regional Director confirmation and Registrar certification constituting conclusive evidence of compliance. Defaults attract daily penalties and may lead to name removal proceedings.
