The Registrar of Companies is an official authorised by the government to maintain a record of all annual reports and other documents issued by a company. This role ensures compliance with statutory filing requirements, contributing to transparency in corporate operations.

Example/Scenario: In the UK, the Registrar of Companies operates through Companies House. If a tech start-up is incorporated as a limited company, it must file annual accounts and a confirmation statement each year. The Registrar ensures that these documents are filed on time, making them available to the public for scrutiny.
