What Are the Memorandum & Articles of Association in the UK

Every company begins with two documents that define its identity. The Memorandum & Articles of Association act as the legal roots of a UK-registered business.

Last year, Companies House processed approximately 846,325 new incorporations. Each one was formed using these same foundational papers, no matter the industry or company size.

Therefore, before forming a limited company, it’s useful to understand what these documents contain, how they operate together, and where they fit in the bigger picture. 

So, let’s explore the Memorandum & Articles of Association side by side and break down their significance with clarity.

What Is a Memorandum of Association?

A memorandum of association acts as the official statement that brings a company into existence. It confirms that the initial shareholders have agreed to form the business and become part of it from the very start. Thus, it is the first step of company formation in the UK.

This document includes:

  • The names of the subscribers,
  • The type of company being created, and
  • The date of incorporation.

Once signed and submitted, the memorandum becomes part of the public record. Its format is fixed and follows a simple layout provided by Companies House.

Although its purpose was broader in earlier versions of UK company law, the Companies Act 2006 revised its role significantly. Before 2009, the memorandum listed objects, share capital details, and other structural rules. Those elements now sit within the articles of association.

The Memorandum & Articles of Association serve different purposes, yet together they form the full legal framework for every company. After registration, the memorandum cannot be changed. Its function is complete. From that point forward, all ongoing rules and internal governance shift to the articles.

What Are Articles of Association?

Articles of association act as the internal rulebook for a company. They outline how decisions are made, how directors operate, and how shares are handled.

Unlike the memorandum, which is fixed after registration, the articles are flexible. Companies can adapt them over time, provided the changes follow the proper legal process. Most businesses start with a standard set called the Model Articles, which meet the needs of many private limited companies.

The content usually covers directors’ powers, voting procedures, dividend rights, and rules around share transfers. These rules apply from the first day of trading and continue throughout the company’s life.

In short, as part of the Memorandum & Articles of Association, the articles provide the ongoing structure a business relies on to function smoothly. Without them, day-to-day decisions would lack direction and legal backing.

Memorandum vs Articles of Association: Key Differences

Before diving deeper, it helps to look at how these two documents compare. Although both are submitted at incorporation, their roles, relevance, and flexibility differ in several important ways.

  • Purpose and Scope

The memorandum confirms that the founding members agree to create the company. It contains only a basic declaration and remains untouched after formation.

On the other side, the articles provide the operational structure. They set rules for directors, voting, share transfers, and other internal matters.

  • Flexibility and Amendments

One cannot modify the memorandum once it has been signed and submitted. Its role ends there. However, the articles offer flexibility. Shareholders may approve changes through a special resolution, which must then be filed at Companies House.

This ongoing adaptability highlights how the Memorandum & Articles of Association serve different functions, despite arriving as a single legal package.

  • Legal Relevance Over Time

In practice, companies rarely refer to the memorandum after incorporation. It becomes a static document, archived and untouched. The articles, by contrast, are consulted regularly. They form the foundation for how a business makes decisions, distributes profits, and manages changes in structure.

For this reason, only the articles continue to influence the company’s internal affairs within the broader framework of the Memorandum & Articles of Association.

  • Pre-2009 Incorporation Legacy

Companies formed before 2009 often included details such as business objects and capital clauses within the memorandum. Those elements are now integrated into the articles for clarity and modern compliance.

As a result, this legal change, introduced through the Companies Act 2006, created a clearer division between a company’s creation and its ongoing governance.

  • Strategic Importance Today

Lastly, articles can be customised to reflect specific needs such as different classes of shares or unique voting rights. This flexibility allows founders and investors to build rules that support long-term growth.

Understanding how the Memorandum & Articles of Association complement one another helps business owners approach formation and governance with greater confidence.

Why Memorandum & Articles of Association are Important

Before building anything meaningful, a business needs a structure. These documents supply that structure from the very beginning. More than mere paperwork, they guide operations, protect interests, and support compliance through every stage of growth. Here’s how they help:

  • Legal Prerequisite for Incorporation

No company can be registered without both the memorandum and the articles. They are required by Companies House as part of the official formation process. Without these, incorporation simply cannot proceed, regardless of the business model.

  • Foundation for Governance

Once the company is formed, these documents create the baseline for how it functions. They provide clarity on roles, decision-making rights, and internal structure. The Memorandum & Articles of Association become the silent framework behind every boardroom conversation and resolution.

  • Protection Through Structure

Clear articles help prevent conflicts between shareholders and directors. By spelling out responsibilities and powers in advance, they reduce uncertainty in future decisions. Therefore, this foresight is particularly useful during ownership changes, disputes, or investment rounds.

  • Confidence in Compliance

Well-prepared governance documents provide confidence to founders, advisers, and investors. They signal that the company has been built with care and legal precision. Reviewing the Memorandum & Articles of Association offers a fast way to assess how seriously a business treats its obligations.

How to Amend Articles (But Not Memorandum)

Company documents aren’t set in stone, at least, not all of them. While the memorandum stays fixed after incorporation, the articles allow some flexibility if your business evolves over time.

To make changes to the articles, shareholders must pass a special resolution. This requires at least 75% approval. Once agreed, the revised version must be filed with Companies House within 15 days. Ignoring this step can lead to administrative delays or compliance issues.

Certain companies may also include entrenched provisions, rules that need added steps or notice periods before amendments are allowed. These provisions often protect minority rights or critical governance clauses.

Businesses that plan to grow or take on new investors often revisit their articles. Amending them allows the internal framework to reflect new goals or responsibilities. Thus, the Memorandum & Articles of Association may start as a single legal bundle, but only one of them truly adapts with the business.

Frequently Asked Questions

1. What is the main difference between the memorandum & articles of association?

The memorandum confirms the intent of founding members to form a company, while the articles explain how that company will be managed. In short, one starts the company, the other keeps it running. For anyone reviewing legal documents for UK company formation, this is a vital distinction.

2. Can a company change its memorandum of association after incorporation?

No, the memorandum becomes a permanent, unchangeable record once submitted to Companies House. Any future changes to internal rules must be made through the articles of association, which offer flexibility as the business evolves.

3. Do all UK companies need both a memorandum & articles of association?

Yes, both documents are legally required when registering a limited company in the UK. They form part of the company’s constitution and are submitted during the incorporation process. Without them, Companies House will not approve the registration.

4. How do I update my company’s articles of association?

To change your articles, pass a special resolution with at least 75% shareholder approval. Then, file the updated articles with Companies House within 15 days. This process allows you to adjust your internal governance while remaining compliant with UK company law.

5. Are model articles suitable for all types of businesses?

Model articles work well for standard private companies limited by shares. However, businesses with specific shareholder arrangements or unique structures often need customised articles. In those cases, using tailored documents gives more control and legal protection over how decisions are made.
