Company Seals in Singapore: When You Still Need One (2026 Guide)
Singapore is one of the clearest examples of a jurisdiction where the company seal has moved from legal requirement to business convention — and where the two are easy to confuse.
What the law says
Since the Companies (Amendment) Act 2017, Singapore companies are not required to have a common seal. Documents that previously needed the seal — including deeds — can instead be executed by signature: either two directors, a director and the company secretary, or a director whose signature is witnessed. The change removed one of the last hard legal uses of the seal for private companies.
The Electronic Transactions Act separately gives electronic signatures legal recognition, and Singapore was an early adopter of the UNCITRAL model rules on electronic transferable records, so even trade documents are steadily going paperless.
What practice still expects
None of that stopped the company rubber stamp from being a daily fixture. In practice you will still be asked for a round or rectangular company stamp when you:
- open or operate a corporate bank account (many banks ask for a stamp on resolutions and forms),
- issue invoices, quotations and delivery orders to counterparties across Southeast Asia who expect stamped documents,
- deal with landlords, suppliers or government-facing paperwork where a stamp signals the document passed through the company, not just an individual.
The stamp has no independent legal magic — it is evidence of company involvement, not a substitute for authorized signatures. But refusing to have one creates friction that costs more than the stamp does.
What a Singapore company stamp looks like
The most common formats:
- Round stamp: company name curved around the rim, registration (UEN) number and "SINGAPORE" along the lower arc, and a plain center or the word "OFFICIAL" — see the corporate seal template for the layout.
- Rectangular endorsement stamp: company name, UEN, address and sometimes "For and on behalf of…" above a signature line.
Blue or black ink is standard; red is common for companies with Chinese business ties. You can assemble either style in the online seal generator in a few minutes and export a transparent PNG for digital documents or an SVG for a stamp maker.
Digital use
For PDFs, place a transparent stamp image with the PDF stamping tool — useful for invoices and quotations where the counterparty expects a stamped look. For contracts where enforceability matters, pair it with a proper e-signature platform; the stamp image itself doesn't prove who applied it. The boundary is explained in electronic seal vs. electronic signature and are image seals legally valid?.
FAQ
Is a company seal legally required in Singapore? No — since 2017 the common seal is optional and signatures can execute deeds.
Do banks require a company stamp? Many still ask for one on account forms and board resolutions as a matter of internal policy. Check with your bank before assuming either way.
Does stamping a contract make it binding? The signatures of authorized persons bind the company. The stamp adds evidentiary weight and meets counterparties' expectations, nothing more.
