What is the primary document that contains a firm's details such as address?

The primary document that contains a firm's details, such as its address, is the Memorandum of Association. This document is essential in establishing the firm’s identity and is required during the company registration process. It outlines the main objectives of the company, its share structure, and the addresses of the registered office, making it a fundamental document for legal and operational purposes.

The Articles of Association, while important, deal more with the internal rules governing the conduct of the company and the rights of its members rather than basic details like the address. The Company Registration Certificate confirms that a company has been legally registered but does not provide comprehensive details about its operations. The Partnership Agreement is specific to partnerships and contains terms agreed upon by partners, but it is not used for limited companies and does not serve the same function as the Memorandum of Association in defining the company’s foundational details.
