For as long as the Companies Act 1967 has existed, every Singapore company has had to keep its registered office physically open to the public for at least three hours during ordinary business hours on each business day. It is one of those quiet compliance obligations that company secretaries build entire office policies around, but that most directors barely think about, until a creditor, member or regulator turns up expecting to inspect the register of members and finds the door locked.
That rule has now been abolished. Under the Corporate and Accounting Laws (Amendment) Act 2025, which commenced its first tranche of provisions on 6 May 2026, the fixed three-hour opening requirement in Section 142 of the Companies Act is gone. In its place is a more flexible, notice-based regime: companies no longer have to keep their doors open on the off-chance someone wants to inspect a register, but they must respond properly once someone actually asks.
This article sets out exactly what has changed, why Parliament made the change, and what directors, company secretaries and registered office providers need to update in their internal processes to stay compliant. It also places the reform in the context of the wider 2025 Amendment Act, which touched several other areas of Singapore corporate law this year.
The Old Rule: Section 142 and the Three-Hour Requirement
Since the Companies Act’s inception in 1967, Section 142 required every company’s registered office to be open and accessible to the public for a minimum of three hours during ordinary business hours on each business day. The policy rationale was straightforward: members, creditors, regulators and other persons with a statutory right to inspect a company’s registers, such as the register of members, register of directors, or register of charges, needed a predictable window in which to do so.
In practice, this created friction. Many Singapore companies, particularly SMEs and startups, do not conduct business at their registered office at all. It is common for the registered office to be the address of a corporate secretarial firm, a virtual office provider, or a small back-office team, rather than a bustling shopfront. Keeping such a location open and staffed for a fixed three hours a day, purely to satisfy a theoretical inspection right that was rarely exercised, was widely seen as a compliance cost with little practical benefit.
What Has Changed Under the 2025 Amendment Act
The Corporate and Accounting Laws (Amendment) Act 2025 was passed by Parliament on 5 November 2025 following a public consultation run by the Ministry of Finance and the Accounting and Corporate Regulatory Authority (ACRA). One of its four broad objectives was to reduce regulatory burden on companies, and the Section 142 reform was the centrepiece of that objective.
Reasonable Notice Instead of Fixed Hours
Instead of a blanket three-hour opening requirement, the amended law now provides that a person who is entitled to inspect a company record must first give the company reasonable notice of their intention to do so. There is no single prescribed notice period in the Act itself; what counts as reasonable will depend on the circumstances, but company secretaries should treat this as an invitation to set out a clear, published process (for example, a standard email address and a stated turnaround time) rather than leaving it to be argued about case by case.
The Two-Hour Inspection Window
Once proper notice has been given, the company must make the relevant record available for inspection for at least two hours on each of the relevant business days. This is shorter than the old three-hour daily requirement, and, critically, it only has to be offered in response to an actual request rather than kept open indefinitely on the off-chance. This gives companies far more flexibility to determine their own registered office operating hours.
Service of Documents Is Unaffected
Directors should note one important limitation: this reform only concerns the inspection of company records. It does not change the rules on service of documents at the registered office. A document can still be validly served on a company by leaving it at, or sending it by registered post to, the registered office, regardless of whether the office happens to be physically staffed or open at that moment. Companies should not read the abolition of opening hours as meaning nobody needs to monitor incoming mail; if anything, the opposite is true, because a missed statutory demand or court document is still treated as validly served.
Why the Change Was Made
In its public consultation, ACRA acknowledged that the original opening-hours rule dated back to a period when registered offices were assumed to be operating business premises. That assumption no longer holds for a large share of Singapore’s corporate population, many of which use a professional registered office address precisely so that the owner’s residential or operating address stays off the public register. Requiring such addresses to be staffed for fixed hours, purely for inspection purposes that were seldom invoked, was judged to be an unnecessary cost that did not meaningfully protect the interests of members, creditors or the public.
The amendment strikes a different balance: it removes the blanket obligation while preserving, and arguably clarifying, the substantive right to inspect. A person who genuinely wants to inspect a register still can, they simply need to ask first, and the company then has a clear, minimum two-hour window within which it must comply.
What This Means in Practice
The table below summarises the practical shift for anyone responsible for a Singapore company’s registered office, whether that is an in-house company secretary, a virtual office provider, or an outsourced corporate services firm.
| Aspect | Old Position (Before 6 May 2026) | New Position (From 6 May 2026) |
|---|---|---|
| Minimum opening requirement | Open and accessible at least 3 hours every business day, regardless of demand | No fixed opening requirement; access is triggered by a request |
| Trigger for access | Automatic, based on the clock | Person entitled to inspect must first give reasonable notice |
| Window once triggered | 3 hours per business day (ongoing) | At least 2 hours on each relevant business day after notice is given |
| Service of documents | Valid regardless of physical opening | Unchanged; still valid regardless of physical opening |
| Section 143 name and UEN display | Required at registered office and place of business | Unchanged |
For registered office and virtual office providers in particular, this is a welcome simplification. It removes the need to roster staff for a fixed daily window purely for statutory optics, while still requiring a genuine, working process for the (comparatively rare) occasions when a member, creditor or liquidator actually wants to inspect a register.
Practical Steps to Update Your Company’s Access Policy
Directors and company secretaries should not treat this as a purely administrative footnote. A few practical steps will keep a company on the right side of the amended Section 142 and avoid disputes with members or creditors down the line.
| Step | What To Do |
|---|---|
| 1. Update internal policy | Replace any internal rule that says “office open 9am to 12pm daily for inspection” with a clear notice-and-response procedure. |
| 2. Nominate a contact channel | Publish a specific email address or contact point for inspection requests, ideally the same one used for other statutory correspondence. |
| 3. Set an internal response standard | Decide, and document, what counts as “reasonable notice” for your company (for example, two business days), and hold to it consistently. |
| 4. Confirm the two-hour window | Once notice is received, block out at least two hours on the relevant business day or days to make the requested record available. |
| 5. Keep registers current regardless | The change affects access hours, not the underlying obligation to maintain accurate registers under Sections 190, 164 and related provisions. |
| 6. Brief your registered office provider | If you use a corporate secretarial or virtual office service, confirm they have updated their own inspection-request procedure to match. |
How This Fits Into the Wider 2025 Amendment Act
The registered office reform was only one of several changes introduced by the Corporate and Accounting Laws (Amendment) Act 2025. Alongside reducing regulatory burden, the Act also tightened rules against the misuse of companies for unlawful purposes (including new express grounds on which the Registrar or the Court must refuse to restore a struck-off company), introduced a new two-tiered shareholder approval process for selective share buy-backs, increased the maximum penalty for breach of directors’ duties under Section 157 from S$5,000 to S$20,000, and required audit reports to name the individual public accountant primarily responsible for the engagement.
Directors who are updating their compliance processes for the registered office change should take the opportunity to review these other amendments as well, since several of them (particularly the increased director penalties and the selective buy-back rules) carry more immediate financial and governance consequences.
Common Mistakes to Avoid
As with any regulatory relaxation, the risk is that companies over-read the change and drop good practices that the law never actually required them to drop. A few common mistakes to watch for:
- Assuming registers no longer need to be accessible at all. The obligation to make records available within two hours of proper notice is still a live legal duty, not a suggestion.
- Ignoring mail because “the office isn’t open.” Service of documents is unaffected by the change; an unopened statutory demand or winding-up application is still validly served.
- Failing to update letterhead and signage obligations under Section 143. The name and UEN display and disclosure requirements were not touched by this reform.
- Treating “reasonable notice” as whatever is most convenient for the company. A pattern of unreasonably long or shifting notice periods could itself be challenged as non-compliant with the spirit of the amended section.
- Forgetting the five-year FYE change rule and other unrelated Part 5 obligations. This reform sits within Division 1 of Part 5 of the Companies Act; other obligations in the same Part, such as annual return filing under Section 197 and financial year end rules under Section 198, are unchanged.
Conclusion
The abolition of the fixed three-hour registered office rule is a small but genuinely useful piece of deregulation. It reflects the reality that most Singapore companies today use a registered office primarily as a legal and correspondence address rather than a walk-in premises, and it replaces a rigid, low-value obligation with a more sensible notice-and-response system. The substantive right of members, creditors and regulators to inspect company records is preserved, and in some respects made clearer, since companies now have an explicit two-hour benchmark to meet once notice is given.
For most companies, the sensible course is to update internal policies and briefing notes now, well ahead of ever receiving an actual inspection request, so that when one does arrive, the response is calm, documented and compliant. If your company’s registered office or company secretarial arrangements have not been reviewed since before 6 May 2026, this is a good moment to do so.
