Apostille Certificates are used to legalise documents so that they can be used throughout the world. Usually companies are required to have their company documents apostilled by the overseas authorities, non-UK registrars and banks. Apostille certificates are issued by the British Foreign & Commonwealth Office. Almost all public documents can be apostilled. Documents can be legalised by apostille as a set or individually.

All limited companies registered with Companies House are required to file annual paperwork. Provided that the company has filed all paperwork since inception and has no outstanding fees, it is said to be in good standing with Companies House. A Certificate of Good Standing can be requested to confirm that the company adheres to all the statutory requirements, that it has filed all the necessary paperwork, has no outstanding fees and no action being taken against the company to remove it from the register. Usually Certificate of Good Standing is requested for opening a business bank account.
