Constitutional documents are legal documents that establish the existence of a company and set out the rules governing its structure and control. They are initially issued upon incorporation of the company and may be amended from time to time.
The exact type of constitutional documents that a company has will depend on the type of company and where it is incorporated. However, constitutional documents are generally those documents that act as proof of existence of the company, proof of ownership and proof of directorship. Such documents include:
Memorandum and Articles of Association (or in some jurisdictions, Articles of Incorporation or Bylaws)
Certificate of Incorporation
Register of Shareholders
Register of Directors
