Company Seal and Authorized Signatory Basics for a New Business

Tap each step for a general overview of how company seal and authorized-signatory requirements typically work when setting up a business.

  1. Understand what represents your company's authority to sign

    In many countries, this is a company seal or stamp; in others, it is simply the authorized signature of a designated officer verified through notarization. Which applies to you depends entirely on your jurisdiction's business registration rules.

  2. Register it with the relevant authority

    Where a formal company seal is used, it is typically registered with a business or company registry at the time of incorporation, after which it becomes the seal used on official filings and major contracts.

  3. Obtain proof of your company seal or signing authority

    Many jurisdictions let you request an official certificate confirming your registered seal or authorized signatory, which is often required alongside contracts or bank filings.

  4. Use a separate working seal for routine business

    To avoid using the primary registered seal for every minor document, many businesses register a secondary "working" seal for day-to-day paperwork, keeping the primary one reserved for major matters.

  5. Use an electronic certificate where available

    A growing number of registries let you request and submit seal-related documents electronically, without an in-person visit, which can meaningfully simplify routine administrative work.

  6. Know the process for loss or replacement

    If a registered seal is lost or needs to be replaced, most jurisdictions require you to file a formal change notice with the registry, which invalidates the old seal and officially registers the new one.

Requirements vary enormously by country

Some countries, including much of East Asia, rely on a formally registered company seal system, where Japan's culture of the personal hanko is a closely related and well-known example. Many other countries, including the United States and much of Europe, instead rely primarily on an authorized signature verified by notarization, with no registered seal at all. Check your own country's business registration authority to find out which system actually applies to you.

This is general information, not legal advice

Exact registration procedures, required documents, and the legal weight given to a seal versus a signature differ significantly by country and even by business type. This page is a general overview; consult your local business registry or a qualified legal professional (such as a corporate lawyer or notary) for guidance specific to your situation.

Frequently Asked Questions

Can a company seal and a personal seal be used interchangeably?

No -- wherever a formal company seal system is used, the registered company seal must be used for the company's official acts, and it should be kept and managed separately from any personal seal belonging to an officer or owner.

Is a secondary working seal required?

It is not mandatory in most systems, but it is widely used in practice, since it reduces the risk of loss or damage to the primary registered seal and makes routine business more efficient.
