The Memorandum and Articles of Association (M&AA) in Singapore is the traditional constitutional document for a Singapore company, though since 3 January 2016 ACRA (1) has required a single Company Constitution instead. Whether you are incorporating today or reviewing an older company’s records, understanding how the M&AA relates to the modern Constitution matters for compliance.
This article explains the M&AA’s original structure, how it became the Company Constitution, its key provisions, and the process for amending it under the Companies Act.
Key Takeaways
- The Memorandum and Articles of Association (M&AA) is the traditional name for a Singapore company’s constitutional document.
- Since 3 January 2016, new companies have filed a single Company Constitution with ACRA instead of a separate M&AA; existing pre-2016 M&AA continue to operate as the company’s constitution.
- The former Memorandum of Association set out a company’s objects and structure, while the Articles of Association governed internal management; both roles now sit inside the Constitution.
- Amending the constitution requires a special resolution passed by at least 75% of votes cast, followed by lodgment with ACRA within 14 days.

Explanation of the Memorandum and Articles of Association
While the specific content may vary based on the government’s regulations and company requirements, understanding the key elements in the Memorandum and Articles of Association is vital for establishing and governing a successful business.
Historically, the Memorandum and Articles of Association in Singapore referred to two separate legal documents: the Memorandum of Association (MOA), which set out a company’s name, objects, and share capital, and the Articles of Association (AOA), which governed its internal management.

Since 3 January 2016, the Companies (Amendment) Act 2014 has required every company to file a single Company Constitution with ACRA instead of a separate M&AA.
Both documents are crucial for a company’s legal and operational framework, albeit with different focuses and audiences, but there are distinct features to remember about these documents.
How does the M&AA relate to a company’s Constitution?
Since 3 January 2016, “Constitution” is the current legal term for a Singapore company’s single governing document, and it has replaced the M&AA for newly incorporated companies.
A company incorporated before that date keeps its existing Memorandum and Articles of Association, which the Companies Act treats as its constitution unless it is later amended into the single-document format.
Both the M&AA and the Constitution are statutory documents governed by the Companies Act 1967; the “Constitution” is not a separate, more flexible category, it is the modern single-document form of the same governing document.
Provisions of the document
The clauses of the Memorandum of Association (also referred to as the company’s charter) include the following information:
- The company’s name and legal status
- The location of the company’s registered office
- The company’s objectives or main objects
- The authorized share capital of the company
- The extent of liability of the company’s members or shareholders.
- The details of the subscribers to the MOA (i.e., the initial shareholders of the company)
Meanwhile, the Articles of Association typically consists of these provisions:
- The rights and responsibilities of shareholders
- The procedures for holding meetings (i.e., annual general meetings, extraordinary general meetings)
- The appointment and removal of directors
- The distribution of profits
- The guidelines for the company’s operations
- Any other rules or regulations that the company wishes to include
Memorandum of association vs. articles of association vs. company constitution
Since the Constitution now covers what the Memorandum and Articles once did separately, the table below shows exactly how each provision maps across.
| Aspect | Memorandum of Association (pre-2016) | Articles of Association (pre-2016) | Company Constitution (since 3 Jan 2016) |
| Purpose | Company name, objects, share capital | Internal governance rules | Combines both roles in one document |
| Filed with | ACRA | ACRA | ACRA |
| Required for | Companies incorporated before 3 Jan 2016 | Companies incorporated before 3 Jan 2016 | All companies incorporated on/after 3 Jan 2016; optional for older companies |
| Amendment process | Special resolution (≥75%) | Special resolution (≥75%) | Special resolution (≥75%), lodged with ACRA within 14 days |
Amendment process
Altering the constitution (formerly the Memorandum and Articles of Association) requires shareholder approval through a special resolution passed by at least 75% of the votes cast by members entitled to vote, with at least 14 days’ written notice of the meeting for a private company.
Since the M&AA and the Articles are now combined into one Constitution, both are amended using the same special-resolution procedure described above; there is no longer a separate, easier process for one part.
In short
The Memorandum of Association focuses on the company’s objectives and activities, serving as an external document that communicates the purpose of the company to external stakeholders.
Meanwhile, the Articles of Association provides internal regulations governing the company’s internal operations, defining the rights and responsibilities of shareholders and establishing the framework for the company’s management and decision-making processes.Both are now combined into the Company Constitution.
Importance of a well-drafted M&AA
A well-drafted Memorandum and Articles of Association forms the bedrock of a company’s governance structure and provides the essential framework for its operations, which includes:
- Ensuring the company’s clarity and certainty
An M&AA helps stakeholders (e.g., shareholders, directors, and employees) understand the company’s goals and operations. The M&AA must be adequately drafted so that the company is compliant with all legal requirements and avoids any disputes or penalties.
- Protecting shareholders’ interests
Having an effective M&AA ensures the shareholders’ interests are protected and that they are treated fairly and equally. Furthermore, it prevents shareholder disputes regarding shareholding due to the rules set forth in the M&AA, which means no conflict remains unresolved.
- Making the right decisions efficiently
The AOA sets out the procedures for holding meetings, appointing directors, and making decisions. An efficient AOA ensures that the decision-making process is efficient, transparent, and complies with legal requirements.
- Increasing flexibility for future changes
You can guarantee flexibility in making changes to the company’s structure or activities in the future, such as issuing new shares, changing the company’s name, or altering the objectives. This flexibility enables the company to adapt to changing market conditions or opportunities.

Process of amending the M&AA of a Singapore company
When it comes to the procedures for changing the Memorandum and Articles of Association in Singapore, it’s crucial to follow a structured process to ensure compliance and transparency with the Companies Act, generally involving the following steps:
Step 1: Identify the need for the change
Determine the specific provisions or clauses in the M&AA that require modification. This could involve reviewing existing provisions, assessing the needs of the company, or addressing regulatory requirements.
It would be beneficial to evaluate the reasons for the proposed changes, such as business expansion, restructuring, or compliance with new regulations.
Step 2: Pass a board resolution
Provide shareholders with sufficient notice of the proposed amendments, as the Companies Act requires. Share the draft amendment with the shareholders and allow them to review and provide feedback if necessary.
Next, hold a general meeting to discuss and vote on the proposed amendments, with the necessary quorum present as per the company’s Articles of Association. This is where you obtain approval from the board of directors or shareholders, depending on the company’s internal governance structure.
Step 3: Prepare the documents
Prepare the amended Memorandum and Articles of Association with the proposed changes incorporated. This typically involves completing several required forms and paying the prescribed fees.
For a smooth process, a cover letter explaining the amendment’s purpose and any supporting resolutions should be provided.
Step 4: File the resolution and updated M&AA
The Accounting and Corporate Regulatory Authority (ACRA) will review the submitted documents for compliance with the Companies Act and other applicable regulations.
If the documents meet the regulatory requirements, ACRA will issue a formal approval and update the company’s records. Once the changes are approved, the company must file a copy of the resolution and the updated M&AA with the ACRA within 14 days.
Step 5: Update internal records
Make sure that all relevant parties, including directors, officers, and shareholders, are aware of the changes. Your company must then update internal company records, including the official register of members, to reflect the amendments.
Remember to communicate the amended M&AA and provide copies of the updated documents for easy access to the changes to relevant stakeholders internally and externally.

Depending on the circumstances and laws applicable to the company, specific requirements may vary. The amendment process should always be navigated effectively with the help of legal professionals or corporate secretaries.
Conclusion
A comprehensive and up-to-date Memorandum and Articles of Association ensures legal compliance, protects shareholders’ interests, and enables efficient decision-making. It also provides the flexibility to adapt to future changes in the company’s structure or activities.
Understanding the intricate provisions within the MOA and AOA enables business owners to navigate the regulatory landscape, foster corporate transparency, and uphold compliance with Singaporean laws.
