Difference Between MOA and AOA

Introduction

When incorporating a company in India, two foundational documents play a crucial role — the Memorandum of Association (MOA) and the Articles of Association (AOA). While both are mandatory under the Companies Act, 2013, they serve distinct purposes.

The MOA defines the company’s constitution, objectives, and the scope of its operations, whereas the AOA lays down the internal rules and regulations for managing the company. Understanding their differences is essential for entrepreneurs, directors, and compliance professionals to ensure smooth operations and legal compliance.

What is MOA (Memorandum of Association)?

The MOA is the company’s charter document. It establishes the legal identity of the company and specifies the powers, objectives, and scope of its activities. It essentially acts as a boundary beyond which the company cannot operate.

Key Functions of MOA:

Defines the name, registered office, and main objectives of the company.

States the liability of members.

Specifies the authorized share capital.

Binds the company to its stated objectives.

What is AOA (Articles of Association)?

The AOA is an internal governance document that outlines the rules for the company’s management. It works in harmony with the MOA but focuses on internal operations rather than external relations.

Key Functions of AOA:

Details the rights, duties, and powers of directors.

Lays down procedures for meetings and decision-making.

Specifies rules for issuing and transferring shares.

Guides internal dispute resolution.
