# Articles of Association: Meaning, Definition and Contents
## Meaning
- The Articles of Association (AOA) are the rules and regulations of a company, framed to manage its internal affairs.
- While the Memorandum sets the external boundary (the fundamental conditions on which the company is allowed to be incorporated), the Articles govern the internal domestic management.
- The articles create rights and obligations between the members and the company.
- The Articles are subsidiary to the Memorandum — they accept the Memorandum as the charter of incorporation.
