What are the legal requirements of a limited by shares company?

All limited companies must be registered with the Registrar of Companies in the UK (Companies House). There is also a requirement to have a registered office address. This must be a physical address and not a PO Box. Details of the registered office are made available to the public. A memorandum and articles of association must also be included with each registration application, and company details should be maintained and any changes must be reported to the relevant authority.
