Introduction
Choosing the right constitution is an important early step when you establish or reorganise a company in Singapore. The constitution sets out the internal rules on governance, shareholders’ rights and directors’ powers and will affect day-to-day decision-making and long-term flexibility.
This article, How to Choose the Right Constitution for Your Singapore Company, outlines who should consider their constitution, the key rules under the Companies Act and practical steps to adopt or amend a constitution. It also explains how a corporate secretary can support filings and ongoing compliance.
Who this applies to
This guidance is relevant to:
- Founders incorporating a new private company limited by shares in Singapore.
- Existing companies considering amendments to their constitution or the use of a bespoke constitution.
- Shareholders, directors and advisers assessing governance arrangements or preparing for investment rounds.
Key rules and requirements in Singapore
Under the Companies Act, a company may adopt a constitution to govern its internal affairs. Many companies use the Model Constitution available under the Companies (Model Constitutions) Regulations, but a bespoke constitution is also common where specific commercial terms are needed.
- Adoption at incorporation: A constitution can be lodged with ACRA via the BizFile+ portal at the time of incorporation. If no constitution is filed, the company is governed by the Companies Act and the Model Constitution by default.
- Amendments: Changes to a company’s constitution generally require a special resolution of the shareholders. A special resolution typically requires at least 75% approval of votes cast, unless the constitution specifies a different threshold.
- Class rights: Variation of rights attached to a class of shares normally requires the consent of the affected class or compliance with the procedure set out in the constitution and the Companies Act (for example, a separate class meeting).
- Filing obligations: After adopting or amending the constitution, the company must lodge the amended constitution and the relevant resolution with ACRA on BizFile+ within the statutory timeframe and keep statutory registers up to date.
- Interaction with other laws: The constitution must operate alongside statutory obligations under the Companies Act, Employment Act, CPF rules, IRAS requirements (including GST and tax filings), and PDPA obligations. It cannot override mandatory statutory rights or public law requirements.
Step-by-step process
Below is a practical process to choose, adopt or amend a constitution for a Singapore company.
- Decide whether to use the Model Constitution or a bespoke constitution. Consider investment terms, share classes, director powers and special commercial arrangements.
- Draft the constitution (if bespoke). Key areas include share capital and transfers, director appointment and removal, quorum and voting, distribution of dividends, pre-emption or drag/tag rights, and dispute resolution.
- Seek shareholder agreement. For an existing company, call the required meeting and obtain the special resolution to adopt or amend the constitution. Ensure notice requirements and meeting formalities under the Companies Act are followed.
- Resolve class rights issues. If a variation affects a class of shares, obtain the necessary class consent or conduct a class meeting as required.
- Lodge documents with ACRA. File the special resolution and the updated constitution on BizFile+ within the statutory period and update statutory registers. Raffles Corporate Services can assist with the filings and related compliance tasks.
- Update internal records and communicate changes. Ensure directors, company secretary, accountants and relevant staff are aware of the changes, and reflect them in corporate policies, bank mandates and payroll arrangements where necessary.
Common mistakes to avoid
- Assuming the Model Constitution always suffices. The Model Constitution is suitable for many small companies, but investor or group structures often require bespoke provisions.
- Overlooking shareholder protections. Failing to include drag/tag, pre-emption, or transfer restrictions can create disputes or unintended share transfers.
- Neglecting filing requirements. Not lodging an amended constitution or resolution with ACRA in the required timeframe can lead to non-compliance.
- Conflicting provisions. Ensure the constitution does not unintentionally conflict with the Companies Act or other statutory obligations (for example, director duties and record-keeping requirements).
- Ignoring practical administration. Complex voting rules or unusual quorum requirements can make routine decision-making cumbersome.
Practical examples
Example 1: Single director-shareholder startup
A single-founder private company may adopt the Model Constitution at incorporation for simplicity. If the founder later seeks investment, the constitution may need to be amended to add preferred shares and investor protections such as information rights and anti-dilution clauses.
Example 2: Foreign-owned company employing staff in Singapore
A company with foreign shareholders should ensure the constitution supports appointment and removal procedures for local resident directors (often required for Employment Pass or local management considerations) and clearly sets out who can sign contracts and manage payroll, CPF and GST obligations.
Example 3: Group company with bespoke governance
A group may require a bespoke constitution to preserve group control, impose transfer restrictions between subsidiaries, and add reserved matters that need supermajority approval. These provisions help protect group strategy and are typically negotiated with investors or lenders.
How a corporate secretary can help
A corporate secretary in Singapore plays a practical and statutory role under the Companies Act. Services commonly provided include:
- Advising on whether the Model Constitution suits the company or whether bespoke provisions are needed.
- Drafting constitution clauses that reflect shareholder agreements, director powers and compliance needs.
- Preparing and convening shareholder meetings, drafting resolutions and ensuring the correct special resolution thresholds are met.

- Co-ordinating with accountants and payroll providers to ensure governance changes are reflected in Financial Year End processes, GST registrations and CPF reporting.
Raffles Corporate Services can assist with these tasks, including filings, compliance, accounting, tax and payroll support if required.
Frequently Asked Questions
Do I have to have a constitution for my Singapore company?
No. A company may rely on the Companies Act and the Model Constitution, but many businesses choose to adopt a constitution at incorporation to set out tailored rules for shareholders and directors.
How do I amend the constitution?
Amending the constitution generally requires a special resolution of shareholders. If the amendment affects a class of shares, you may also need class consent. After adoption, the company must lodge the amended constitution and the resolution with ACRA using BizFile+ within the statutory timeframe.
Can the constitution override the Companies Act?
No. The Companies Act contains mandatory provisions that cannot be overridden by a constitution. Any constitution clause that conflicts with mandatory statutory requirements will be ineffective to the extent of the inconsistency.
Should I include investor protections in the constitution?
Investors commonly negotiate rights such as pre-emption, drag/tag, information rights and reserved matters. Whether to include these in the constitution depends on the investment and corporate structure; discuss options with your advisers.
