Singapore Company Constitution Guide
A Singapore company constitution is one of the most important legal documents established at incorporation. It sets out the company's structure, its decision-making processes, the rules for issuing and transferring shares, and the rights and obligations of shareholders and directors.
Although many founders treat the constitution as a standard incorporation formality, it directly shapes how the company is governed and how shareholders and investors interact. A well-drafted constitution gives founders and shareholders a clear legal framework, one that holds up when disputes arise and keeps the company compliant with the Singapore Companies Act.

Key Takeaways
Every Singapore company must adopt a constitution at incorporation and register it with ACRA.
The constitution regulates share structure, director powers, meetings, dividends, and internal governance rules.
Certain clauses are mandatory, including the company name, registered office, liability, share capital, and subscriber details.
Companies may adopt ACRA's Model Constitution or register a customized version tailored to their ownership structure.
The constitution has statutory contractual effect and binds the company and its members, but not third parties.
Amendments require a special resolution and must be filed with ACRA within 14 days.
What Is a Singapore Company Constitution?
A Singapore company constitution is a legal document filed at incorporation that sets out the rules governing a company's structure, internal management, the rights and obligations of its shareholders and directors, as well as other mandatory and non-mandatory provisions. It has statutory contractual effect under the Singapore Companies Act.
Since the Companies (Amendment) Act came into effect in 2014, the former Memorandum of Association and Articles of Association have been merged into a single document known as the constitution. For companies incorporated before the amendment, their existing Memorandum and Articles continue to operate as their constitution unless amended.
In practice, the constitution acts as the company's internal rulebook and is legally binding on the company and its members. It becomes particularly important when multiple shareholders or investors are involved.
Is a Constitution Mandatory for a Singapore Company?
A constitution is a mandatory incorporation document submitted to ACRA at the time of incorporation. A company cannot be incorporated without adopting a constitution, whether it chooses to use the Model Constitution provided by ACRA or a customized version.
The requirement applies to private companies limited by shares, public companies, companies limited by guarantee, and other company types registered in Singapore.
While the Companies Act does not prescribe a fixed template that must be followed in all cases, any provision in the constitution that is inconsistent with the Act will be unenforceable.
Mandatory Clauses in a Singapore Company Constitution
1. Name Clause
The constitution must state the company's approved name as registered with ACRA. The company must carry on business and issue official documents under this exact name.
Before incorporation, the proposed name must comply with ACRA's naming requirements, including restrictions on undesirable, identical, or regulated names. You may refer to our detailed guide on Singapore Company Name Approval for practical requirements and approval considerations.
2. Registered Office Clause
3. Liability Clause
4. Share Capital Clause
The constitution must set out the company's share capital structure and its division into shares.
Under the current Companies Act framework, there is no requirement to state authorised share capital.
5. Subscriber Clause

Non-Mandatory Provisions Commonly Included in a Company Constitution
Share Structure and Share Transfers
A constitution commonly sets out the rights attached to shares and the procedures governing their transfer.
Typical provisions include:
- Different classes of shares and their respective rights
- Restrictions on transfer of shares
- Pre-emption rights
- Procedures for approving or refusing share transfers
- Transmission of shares upon death or bankruptcy
Directors: Appointment, Powers and Duties
Most constitutions include provisions regulating:
- Appointment and removal of directors
- Directors' powers to manage the company
- Delegation of authority
- Board meeting procedures
- Appointment of managing or alternate directors
Although directors' statutory duties are governed by the Companies Act and common law, the constitution clarifies how managerial authority is exercised internally.
Clear drafting in this section becomes especially important in companies with multiple shareholders or nominee directors, where board control mechanisms must be carefully structured.
General Meetings and Written Resolutions
The constitution typically regulates how shareholder decisions are made.
Common provisions include:
- Calling and conducting general meetings
- Notice requirements
- Quorum and voting procedures
- Use of proxies
- Written resolutions
Without clear rules in place, it is easy for shareholders to later challenge the validity of decisions made at meetings.
For small private companies, written resolutions are frequently used in practice as they allow decisions to be passed efficiently without holding physical meetings.
Dividends and Reserves
Most constitutions contain provisions governing the declaration and payment of dividends.
These typically address:
- The authority of directors to recommend dividends
- Approval of dividends by shareholders
- Payment procedures
- Creation and use of reserves
While the Companies Act sets out solvency requirements and restrictions on distributions, the constitution clarifies the internal approval process and allocation of profits.
In practice, clear dividend provisions are important in companies with multiple shareholders, especially where profit distribution expectations differ among founders and investors.
Company Secretary and Common Seal
Most constitutions include provisions regarding the appointment and removal of the company secretary.
They may also regulate:
- Duties and authority of the company secretary
- Custody and use of the common seal
- Execution of documents
Although the use of a common seal is no longer mandatory under Singapore law, many constitutions still contain provisions governing its use, particularly for companies incorporated using older templates.
Financial Statements and Accounting Records
Although statutory accounting obligations arise under the Companies Act, constitutions often reinforce the company's duty to maintain proper accounting records.
Provisions may address:
- Preparation of financial statements
- Circulation of financial reports to members
- Appointment and removal of auditors
- Inspection rights of members
Winding Up and Indemnity
Constitutions typically contain provisions addressing voluntary winding up and the distribution of assets upon liquidation.
They may also include indemnity clauses protecting directors, officers, and the company secretary against liabilities incurred in the proper discharge of their duties, subject to statutory limitations.
Indemnity provisions must comply with the Companies Act, which restricts the extent to which a company may exempt officers from liability. Proper drafting ensures these clauses remain enforceable.
How to Draft a Company Constitution?
A Singapore company constitution should comply with the Companies Act and reflect the company's ownership setup, how it plans to operate, and whether fundraising or share transfers are on the horizon.
The starting point is always statutory compliance. Any provision that conflicts with the Companies Act will be invalid to the extent of the inconsistency, so it is worth getting this right from the outset.
Companies generally have two options:
- Adopt the Model Constitution provided by ACRA; or
- Register a customised constitution tailored to their specific needs.
The Model Constitution is suitable for many startups with simple shareholding structures. However, a customised constitution is often advisable where:
- There are multiple founders with different rights
- Different classes of shares are issued
- Investor protection provisions are required
- Share transfer restrictions need to be carefully structured
It is also important to ensure consistency between the constitution and any shareholders' agreement. Inconsistencies between the two documents can create legal uncertainty and enforcement challenges.
Model Singapore Company Constitution by ACRA
Singapore companies may adopt the standard Model Constitution issued by ACRA at incorporation. It is designed for companies with straightforward ownership and governance arrangements.
The Model Constitution is prescribed by the Accounting and Corporate Regulatory Authority under the Companies Act, and companies can adopt it in full without needing to prepare a customized document.
The Model Constitution covers key governance matters, including:
- Share capital and share rights
- Appointment and powers of directors
- Conduct of general meetings
- Dividends and accounts
- Transfer of shares in private companies
For a detailed explanation of how the Model Constitution works and when it is appropriate to use it, refer to our comprehensive guide on Singapore Model Company Constitution.
Adoption of Company Constitution
A company constitution in Singapore is adopted at incorporation and registered with ACRA as part of the company formation process. It must remain in force for as long as the company exists.
The constitution is submitted electronically during the incorporation filing with ACRA. Upon registration, it takes legal effect from the date the company is incorporated.
Each subscriber to the constitution must agree to become a member of the company and subscribe to the stated number of shares. The incorporation filing also includes declarations by the proposed directors and company secretary confirming compliance with statutory requirements.
After incorporation, the company must keep its constitution at its registered office address. Members are entitled to inspect the constitution and request a copy, subject to any prescribed fee.
Legal Effect of a Company Constitution
Binding Effect Between Company and Members
The constitution binds the company to its members and the members to the company.
If the company acts in breach of its constitution, a member may seek legal remedies, including an injunction to restrain the company from acting inconsistently with its provisions. Similarly, members must comply with obligations imposed on them under the constitution.
Binding Effect Among Members
The constitution also creates a contractual relationship among members in their capacity as members. Where the constitution grants rights to members, those rights may generally be enforced through the company. This is particularly relevant in matters involving share transfers, voting rights, and dividend entitlements.
In practice, disputes between shareholders often involve interpretation of constitutional provisions governing these rights.
Why It Does Not Bind Third Parties
The constitution does not create contractual rights for external third parties who are not members of the company.
Even if a provision appears to benefit an outsider, that person cannot enforce it solely on the basis of the constitution. Any enforceable rights in favour of third parties must arise from separate contractual arrangements.
How to Amend a Singapore Company Constitution?
A Singapore company may amend its constitution by passing a special resolution of shareholders and filing the required notice with ACRA.
Under the Companies Act, any alteration of a company's constitution must be approved by special resolution, which generally requires at least 75 percent of votes cast by members entitled to vote.
Once the special resolution is passed, the company must lodge the relevant notice of amendment with ACRA within 14 days. The amendment takes effect from the date the special resolution is passed, unless otherwise specified or subject to statutory restrictions.
Amendments are commonly required when:
- Introducing new classes of shares
- Revising share transfer restrictions
- Implementing investor rights
- Updating governance structures
- Aligning the constitution with a shareholders' agreement
As with the original constitution, any amendment that contradicts the Companies Act will not be enforceable.

Founder, Aeternis Asia Pte LtdPractical Considerations for Founders
Founders should think of the constitution as more than a filing requirement. It should reflect their fundraising plans, shareholder arrangements, and how they intend to maintain control over the company long term.
Although many startups adopt the Model Constitution at incorporation for simplicity, founders should consider early on whether it actually suits their ownership and management setup.
Founders should consider:
- Whether different share classes may be issued in the future
- How share transfers should be controlled
- How board control and decision making authority are structured
- Whether investor protection provisions may be required
- Whether the constitution aligns with any shareholders' agreement
It is generally easier and more cost effective to structure governance provisions properly at incorporation rather than amend the constitution during an investment round.
