Surprising fact: since 31 March 2017, a common seal is no longer required for most formal documents in local law — a change that affected thousands of firms overnight.
This short guide explains what people mean when they search “company seal requirement singapore” and why many organisations no longer need a physical seal to execute documents.
We will set clear expectations: when a seal is optional, when a rubber stamp can be helpful, and how to sign correctly under section 41B of the Companies Act.
At a high level, the law changed to simplify execution methods and cut administrative friction while preserving legal enforceability. Still, counterparties such as landlords, banks or overseas clients may ask for a seal or stamp as a matter of policy.
Later sections signpost step-by-step: uses, the post‑2017 change, how to sign under section 41B, where to order a seal or stamp, and how to control them internally for proper compliance.
Key Takeaways
- The common seal is generally optional after 31 March 2017.
- This guide shows when a stamp may be practical.
- Section 41B provides accepted signing methods.
- Some counterparties may still request a seal or stamp.
- Internal controls remain important for legal compliance.
What a common seal is and what it’s used for
A common seal is a metal embossing tool that once served as a formal mark of corporate authority.
The embossed impression helped third parties recognise that a document was intended to bind the firm. It was commonly applied to formal instruments to show authentic execution under older practice.
- Contracts and long-form agreements;
- Share certificates issued to shareholders;
- Deeds and other formal instruments requiring prominent authentication.
By contrast, a company stamp or rubber stamp is an inked imprint used for day-to-day endorsement. A rubber stamp usually carries the entity name and UEN and is convenient for routine paperwork, but it does not produce the raised, official impression of an embossed tool.
| Feature | Embossed common seal | Company stamp |
|---|---|---|
| Appearance | Raised, metallic impression | Flat, inked mark |
| Typical use | Formal execution of documents | Routine endorsements and invoices |
| Perceived formality | High | Low to medium |
Misconceptions persist that a stamp equals a seal. Relying on the wrong method risks ceremony flaws. The Companies Act now accepts specified signature methods, which reduces reliance on physical impressions while keeping documents enforceable.
company seal requirement singapore after the Companies Act changes
Since 31 March 2017, firms may often rely on authorised signatures instead of a physical impression. The legal shift means a common seal is no longer mandatory for many formal acts.
What changed
The Companies Act removed the automatic need to press an embossed mark when executing deeds or issuing share certificates. Both companies and LLPs now commonly execute documents by authorised signatories.
Practical consequence
- Fewer administrative steps and less reliance on metallic tools for routine signings.
- Deeds can be signed by authorised signatories rather than being embossed.
- Entities should still ensure correct signing formalities to avoid defects.
When a common seal may still be used
Some firms keep rolling practices for internal policy, legacy workflows, or because overseas counterparties expect a pressed impression. Conservative financial institutions or specific templates may still request it.
| Aspect | Before 31 Mar 2017 | After 31 Mar 2017 |
|---|---|---|
| Mandatory use | Common seal often required | Not mandatory; signature routes accepted |
| Operational impact | Extra embossing step | Fewer physical steps; simpler execution |
| When still used | Widely for formal instruments | By policy, legacy habits, or counterparty demand |
Tip: check counterparties’ expectations early and update templates that still say “signed, sealed and delivered” if relying on signature execution under the Companies Act. For the recognised signature routes, see section 41B in the next section.
How to execute deeds and formal documents without a common seal (Companies Act section 41B)
Execution under Companies Act section 41B permits three accepted signing routes so firms can lawfully finalise deeds and other formal documents without a pressed impression.
Signing by a director and a company secretary
Step 1: confirm who currently holds office. Check ACRA records or board minutes to verify the director and the company secretary authorised to sign on behalf of the company.
Step 2: both sign the final page and date it. Match the printed names to official registers to avoid later challenge.
Signing by at least two directors
Arrange same-day signing where possible. Two directors must sign the deed so names, signatures and dates align with ACRA information.
Practically, prepare a signing list and circulate the locked final version to prevent mismatches between drafts.
Signing by a director in the presence of a witness
The director signs while the witness watches and then the witness attests the signature. Attesting means the witness signs, prints their name and dates the document.
Witnesses should not be beneficiaries under the deed and should record contact details in the file.
Practical checklist before execution
- Confirm board or delegated authority to execute on behalf of the company.
- Lock the final document version and all annexures before signing.
- Match signatory names to registers and note their capacity.
- Keep an executed copy in statutory records and the transaction file.
- Use corporate secretarial services for complex signing matrices, frequent transactions or unclear constitutions; see their terms.
Good record-keeping reduces later disputes where a counterparty claims an earlier draft was signed. For guidance on electronic execution of deeds and related law reform, consult the electronic deeds guidance.
How to create a company seal or company stamp in Singapore
Preparing a pressed impression or an inked stamp starts with deciding which tool suits your daily workflows and counterparty expectations.
Practical difference: metallic embossers produce a raised, formal impression for presentation and deeds. Rubber stamps offer quick, repeatable inked marks for invoices, delivery notes and routine forms.
What to include
Always include the business name and the registration number (UEN). Accuracy matters: matching ACRA records avoids rework and rejected paperwork.
Optional additions: telephone, limited address lines, date boxes or a small logo where useful.
Materials and formats
- Embossing presses: metal, table-mounted for formal documents.
- Rubber stamps: wood, plastic or self-inking; available as pocket or table designs for portability or desk use.
- Pocket models suit field teams; table styles suit administrative desks.
Ordering, proofing and turnaround
Vendors usually ask for the name, UEN/registration number and any artwork. Approve a digital proof before production to prevent mistakes.
Expect typical prices from S$10 to S$35 and delivery from a few hours to a few days. Custom designs and security features will add cost and time.
Design and fraud-reduction tips
- Use a unique layout and include a small logo to deter forgery.
- Limit long address lines; excessive detail can be copied and becomes cramped.
- Consider optional security options such as UV ink, microtext or holographic labels where risk is higher.
Maintenance: keep ink pads fresh, replace worn rubber, and store embossers safely so impressions stay legible for records.

How to use a company stamp correctly on day-to-day business documents
A clear stamping routine keeps routine paperwork moving and avoids confusion at the point of processing.
Where and how to place an imprint. Place the stamp near the signature block or in a designated endorsement box. Keep the impression centred and legible. Avoid covering printed text or dates.
Common operational uses
Typical stamps speed up handling of invoices, purchase orders and delivery notes. They are also used on rental agreements, grant applications and business contracts where a chop is expected.
When a stamp is unnecessary
If the UEN or registration number already appears clearly on invoices, statements or business letters, an imprint usually adds no legal value. In such cases, skip stamping to avoid clutter.
Statutory display of the UEN
Plain English: under the Companies Act s.144(1A) the UEN must be legible on business letters, statements of account, invoices and official notices issued on behalf of the company.
Practical layout examples
- Invoice header: business name — UEN — contact details.
- Letterhead footer: UEN in the bottom centre or left.
- Template block: a small, labelled field for UEN near the signature line.
| Document | Stamp recommended | UEN visible avoids stamp |
|---|---|---|
| Invoice | Yes — for fast processing | Yes — if UEN in header |
| Purchase order | Yes — approval mark | No — only if UEN printed |
| Rental agreement | Optional — counterparty preference | Yes — if UEN in contract header |
| Grant application | Yes — common request | No — if registration number included |
Note: a company stamp or rubber stamp does not replace proper authorisation. Where execution requires authorised signatories, obtain signatures rather than relying on an imprint to endorse documents.
Policy tip: set simple internal rules that list when staff may apply a stamp and when they must route papers for signature. This avoids delays and accidental over‑endorsement.
Compliance and governance: controlling seals, stamps, and document endorsement
Practical controls around stamps and embossers protect the organisation from fraud and apparent authority claims. Good governance matters even when a pressed mark is optional.
Custody and authorised use
Store physical tools in a locked location and keep a sign‑out log. Limit access to specific roles and record each imprint occasion.
Simple steps: secure storage, role-based permission, and a dated record reduce misuse of stamps and seals.
Internal policy and constitution alignment
Update the constitution and signing policies to reflect section 41B signing routes. Make clear when staff may endorse documents and when to escalate to a director or secretary.
Workflows and when to get help
Adopt template control, approval checkpoints and central archiving so executed papers are easy to audit. Engage corporate secretarial services for high-volume executions, cross-border deals or when amending constitutional clauses.
- Why this matters: consistent controls improve compliance, cut dispute risk, and prevent unauthorised stamping being treated as apparent authority.
Conclusion
When speed and clarity matter, authorised signatures are often the simplest way to close legal paperwork.
In short, a common seal is generally unnecessary since 31 March 2017, but you must still execute documents correctly. Use one of the three section 41B signing routes as your default to avoid delays at closing.
Remember the practical difference: a common seal is an embossed, formal tool; a stamp is a day‑to‑day imprint that speeds processing but does not replace proper execution.
Ensure the UEN is legible on official papers, keep simple governance controls for custody and use, and review templates and signing policy. This small review will reduce fraud risk and keep your business compliant.
