Company Seal

Businesses issue contracts, forms, certificates and letters, and a physical mark can help identify a company, but it does not by itself prove that the right person approved a document. Treat the mark and signing authority as separate questions.

A formal common seal may be governed by company law and internal rules, while a rubber or self-inking company stamp may simply show the name and licence details for administrative use, and people sometimes call both a company seal, which creates confusion. For example, the UK Companies Act 2006 says a company may have a common seal but need not have one, and it also provides a signature route for certain documents.

At the other end, an official DMCC guideline describes a company stamp as mandatory for its licensed-company context and specifies a company-name policy, though this older published guideline should be checked against current DMCC requirements before use. The federal commercial companies law, a free-zone authority's procedures and a bank's onboarding checklist answer different questions, so do not infer from one source that every authority or counterpart accepts an unstamped form.

A stamp is not a substitute for an authorised signatory, and if a person lacks authority to commit the company, a mark should not be treated as automatic approval. Conversely, a properly executed document may not need a mark in a jurisdiction where signatures suffice.

A receiving party can also have its own process, as a tender portal, bank or supplier might request stamped paperwork even if a general law does not demand a common seal, and a licence authority may prescribe the business name, language or location the stamp must display. Keep the physical device secure by restricting access to a named custodian, recording requests and approving use under a delegation policy, because a stamp left in an open drawer can be misused, and a usage log noting the date, document, requesting person and authorising person helps, although the log is not approval.

Update or retire the device when the company name or licensed details change so the obsolete stamp cannot be used accidentally. Digital workflows require their own check, since a pasted image of a rubber stamp is not automatically a compliant electronic signature or electronic seal.

Verify the relevant law, platform controls and counterparty acceptance, remembering that anyone with an image may be able to copy a mark, so its strength depends on custody and context. A company may have multiple branches or legal entities with similar names, so match the mark to the exact contracting entity.

A common seal can be used on deeds or formal instruments in certain systems, while routine stamp use may be administrative, and the precise categories vary, so get advice on a specific document instead of translating the terms loosely. For a cross-border agreement, both the company's capacity and the receiving jurisdiction's formalities may matter, and notarisation or attestation can be separate from a stamp.

Cost is usually a minor part of this decision, since the bigger cost is delay or a disputed document when a bank or authority rejects it, and if a recipient insists on a stamp the company should identify its written requirement and the correct entity, then route the document to the authorised person rather than stamping it before internal approval. The practical question is not whether every company needs a stamp, but what this entity must have and how this particular document must be approved, signed and delivered, so recheck current local requirements when the answer will drive action and use the seal as one controlled part of document governance.
