Which document generally outlines the regulations governing a company's internal management?

The articles of association serve as a crucial document that outlines the internal regulations governing a company's management. This document sets out the rules and procedures for the governance of the company, including the rights and responsibilities of directors and shareholders, the conduct of meetings, and the process for decision-making. It essentially acts as a framework for how the company operates on a day-to-day basis and how it regulates its internal affairs.

The articles of association complement the memorandum of association, which primarily focuses on the company's external structure and illustrates its relationship with the outside world. Unlike a shareholders' agreement, which usually addresses the rights and obligations of shareholders in relation to each other and the company, the articles of association are mandatory for compliance with corporate law and govern the company's internal processes.

Bylaws, while they can outline additional rules for governance, are typically more common in nonprofit organizations and may vary significantly from one entity to another. Therefore, within the context of corporate regulation, the articles of association are the definitive document detailing how the company is to be managed internally.
