A Memorandum of Association is a document produced when a company is formed. It includes the names of all subscribers to the memorandum and confirms that those named wish to form the company and take at least one share.
Companies House produces the document automatically when you register your company online. For paper applications, though, you must complete it yourself and request signatures from all subscribers.
A record of the Memorandum of Association will be kept online at Companies House, and can be accessed by the public through the Companies House website.
