How to Change Your Company's Constitution in Singapore
Summary
75% is the bar: Amending your constitution requires a special resolution passed by at least 75% of shareholders present and entitled to vote, well above an ordinary resolution's simple majority.
The 14-day Accounting and Corporate Regulatory Authority (ACRA) deadline runs separately from the vote: Once the resolution passes, you have 14 days to lodge the amended constitution via BizFile+. Miss this window and your public record falls out of step with the governance you've adopted.
Fundraising is the most common trigger: Investors routinely require preference shares, drag-along and tag-along rights, or protective provisions that ACRA's generic model constitution doesn't include.
In Singapore, most companies incorporate on ACRA's generic model constitution and never look at it again. This all changes when an investor's lawyer flags a provision that the term sheet requires but is missing from your company constitution.
You will need to add the flagged provision to the document, but making the change is fairly complex. To make the change, you need a special resolution backed by at least 75% of shareholders present and entitled to vote. After the change is made, you have just 14 days from the resolution passing to lodge the amended constitution with ACRA.
Should you fall short on the vote or you file the amendment late, you will open a compliance gap that will trigger complications with bank dealings or investor due diligence.
This article walks you through the requirements of changing your company constitution in Singapore, and the steps you need to take to make the change.
What Does a Company Constitution Govern in Singapore?
Let’s start by understanding what your company constitution is. In essence, it is your internal rulebook for how your company runs, covering:
How shares can be transferred
How directors are appointed and removed
How meetings are conducted and what rights each class of shareholder holds.
Many companies tend to adopt ACRA's model constitution at incorporation and never revisit it, which works until the business outgrows a template written with no particular company in mind.
Most amendments start from the gap between the template and what a growing company needs. A model constitution assumes a simple ownership structure and a small, aligned founding team, and does not account for preference shares, board observer rights or specific governance mechanics.
The document stays as it is until someone amends it, so a company can run on an outdated constitution for years without anyone noticing. Oftentimes, it takes a specific event to bring the mismatch into view, which takes time and effort to rectify.
When Do You Need to Amend Your Company's Constitution?
Preference share classes for investors drive the most amendments, because standard constitutions typically provide only for ordinary shares. Updated pre-emption rights are another frequent addition as a company takes on more shareholders. They give existing shareholders first refusal on new share issues.
Changes to board composition and voting thresholds tend to follow as a company matures past its founding structure. A two- or three-person board that worked at incorporation usually needs more formal governance by then.
Each trigger brings its own timing pressure. Preference share amendments arrive attached to a live funding round with a closing date. Pre-emption updates often follow a dilutive event that made existing shareholders pay closer attention to future issues. Governance changes are rarely urgent on their own. Still, as they pile up, your business may need to bundle several overdue changes into one amendment once it finally schedules the meeting.
The Special Resolution Threshold to Amend a Company Constitution
Now that you understand the basics of your company constitution, let’s move on to consider the requirements of amending it. On the whole,
A special resolution needs at least 75% of the votes cast by shareholders present and entitled to vote at the meeting. The threshold is the same at an annual general meeting (AGM) or at an extraordinary general meeting (EGM) called for the amendment.
An ordinary resolution only needs a simple majority. The higher bar for a special resolution exists because the constitution affects every shareholder's rights, including those outside the majority.
Reaching 75% in a company with several unrelated shareholders takes coordination. Confirm your voting support before you schedule the meeting, so a shortfall doesn't catch you out on the day. Your risk is highest when early angel investors or advisors hold small stakes and don't respond to a meeting request on short notice.
How to Change a Company Constitution in Singapore: The ACRA Filing Process
Once you know the votes are in place, the rest of the process is procedural. Broadly, these are the next steps you’ll need to take:
Draft the amendment. This might be a full overhaul or a targeted change to one clause. Our corporate secretary team at Mezzanine Enterprise takes care of these amendments for our clients.
Circulate the constitution with the meeting notice. Shareholders need to see the exact wording they're voting on, so make sure you send the drafted text instead of a summary of what you intend.
Pass the special resolution at the AGM or EGM with at least 75% of the votes cast.
Lodge the amended constitution with ACRA via BizFile+ within 14 days of the resolution passing.
The lodgement step carries as much weight as the vote. Until the amendment is lodged, it will not be reflected on ACRA's public record, which is what banks, investors and other counterparties examine. Passing the resolution internally and making the amendment visible externally are two separate milestones.
What Happens if You File a Constitution Amendment Late?
It is essential that you file your constitution amendment on time, as a late filing leaves your public record out of step with your governance. Between the company and its shareholders, the amendment takes effect once the resolution passes. An investor's due diligence team checking ACRA, though, will see the old constitution while your company runs on the new one.
This mismatch may trigger an inquiry that slows down or complicates a deal. It also tends to come up late in a transaction timeline, when every extra query costs momentum. Lodging within the 14 days keeps the two records in step and takes the question off the table.
How to Amend a Constitution You've Already Customised
A bespoke constitution takes more care to amend than ACRA's model. The more changes are proposed, the greater the risk of errors. Before drafting, check how each proposed change interacts with the existing clauses. Pay particular attention to share classes, board powers, and any protective provisions already granted to earlier investors.
A change that looks self-contained on paper can conflict with a right an earlier shareholder already holds. A careful drafting review catches the conflict before the resolution goes to a vote. Unwinding a defective amendment after it has passed is far harder than fixing the draft.
Restrictions on What You Can Amend in a Company Constitution
Even a 75% vote has limits. Rights attached to a specific class of shares sometimes need that class's separate consent before they can be varied, on top of the general 75% threshold across all shareholders.
If your company has more than one share class in issue, check whether a class-consent requirement applies before taking action on just one special resolution. Finding out after the general vote means running a second approval process you hadn't planned for, and you would need to arrange another round of votes on a timeline that may not suit your class shareholders.

Frequently Asked Questions
What's a special resolution and why does this need one?
A special resolution is a shareholder resolution that needs at least 75% of the votes cast by shareholders present and entitled to vote. By contrast, an ordinary resolution only needs a simple majority.
Amending a company constitution requires a special resolution as it affects every shareholder's rights, including the rights of shareholders outside the majority.
How long do I have to file with ACRA?
You have 14 days from the date the special resolution passes to lodge the amended constitution with the Accounting and Corporate Regulatory Authority (ACRA) via BizFile+. Treat it as a hard deadline. A late filing doesn't invalidate the amendment between shareholders, but it leaves your public ACRA record out of date, which is the record banks and investors check.
Can I use ACRA's model constitution, or do I need a custom one?
Yes, you can. In fact, most companies start with ACRA's model constitution when they incorporate. However, it may not be ideal if your business raises investment or grows past a simple founding structure. This means you’ll need custom provisions that ACRA’s model doesn't include, such as preference share classes or protective board provisions.
What happens if my company operates under an outdated constitution?
You run the risk of not being able to grant the rights your investors or governance arrangements require. Any due diligence check will also surface the mismatch between your actual arrangements and your official constitution. Starting the amendment when term sheet negotiations begin gives you time to close the gap before a deal depends on it.
Do all shareholders need to agree to amend the constitution?
No. An amendment to the constitution only requires at least 75% of the votes cast at the meeting. Some amendments that affect a specific share class may also need that class's separate consent, on top of the general vote.
