A company stamp is not mandatory in Singapore. Since amendments to the Companies Act took effect in 2017, a company is no longer required to have a common seal, and documents can be validly executed without one. Yet most businesses still keep a stamp. This guide explains why.
What the law says
Before 2017, companies commonly used a common seal to execute deeds and certain documents. The law was amended so that a company may execute documents by the signature of authorised persons (such as directors or the company secretary) without a seal. Having a seal — or a company stamp — is now optional.
Common seal vs company stamp
The two are often confused. A common seal is a formal embossing/sealing device historically used for deeds; a company stamp is an ink stamp showing the company name and details. We compare them in detail in company stamp vs common seal.
Why most businesses still use a stamp
- Recognition. Banks, government agencies and counterparties still expect a stamped document in many routine situations.
- Authenticity. A stamp signals the document was issued and approved by the company.
- Consistency. It reinforces a uniform corporate identity alongside your logo and signatures.
Getting one without overspending
Because a stamp is optional, there is no need to overspend. You can design one free and download a transparent PNG for digital documents, then order a physical stamp only if you need a hard copy. Learn what to put on it first.
