On a paper document, the corporate seal belongs next to the signature of the officer executing the document on the company’s behalf. If the page shows a printed “SEAL” box or the letters “L.S.” near the signature line, use that spot. If not, press the embosser or stamp just below or just to the left of the signature, in a clear area where the impression won’t cross printed text or another signature. That is the short answer to where to place a corporate seal on a document, and the rest of the guidance below is really about applying it cleanly to the kind of document in front of you.
What the Seal and the “L.S.” Marker Look Like
A corporate seal is either a metal embosser that presses a raised impression into the paper or a rubber stamp that leaves an ink print. The impression normally shows the company’s legal name, the state of formation, and the year of formation.
You may also see the letters “L.S.” printed on a signature line. The abbreviation is short for the Latin locus sigilli, meaning “place of the seal,” and it marks the exact spot the seal was historically expected to go. In modern practice “L.S.” sometimes stands in for a physical seal on its own, signaling that the parties intend the formality of a sealed instrument even without an actual impression on the page.
Placement by Document Type
The rule is the same across documents: keep the seal next to the executing signature, visible, and clear of text. The conventions below just tell you which signature.
Contracts and Agreements
On a contract, the seal goes inside or beside the signature block for the corporation. Use any printed “SEAL” or “L.S.” space; otherwise press the seal just below or to the left of the authorized officer’s signature. On a multi-page contract, the seal goes on the signature page only, unless the other party or local practice calls for something else.
One narrow point worth knowing before you reach for the embosser on a sales contract: under UCC ยง 2-203, attaching a seal to a contract for the sale of goods does not make it a sealed instrument, and the special rules that apply to sealed instruments do not apply to that transaction.1Legal Information Institute. UCC 2-203 Seals Inoperative You can still put the seal on the document; it just won’t change its legal character.
Deeds and Real Estate Documents
On a deed from a corporate grantor, the seal goes next to the corporation’s signature, near the attestation clause confirming the seal was affixed by authority of the board. Some recording offices still expect a corporate seal on entity deeds, though the requirement varies by jurisdiction. If the corporation has no seal, the acknowledgment can say so.
Stock Certificates
On a stock certificate, the seal goes on the face of the certificate, typically near the signature of the corporate secretary or president. State statutes generally provide that each certificate “may bear the corporate seal or a facsimile of the corporate seal,” so the seal is optional in this context but customary.
Corporate Resolutions and Meeting Minutes
On resolutions and minutes, place the seal next to the signature of the corporate secretary or whoever is certifying the document as accurate. This matters most when a bank or government agency has asked for a certified copy; the seal signals that the copy is an authentic corporate record.
Documents Headed for Apostille or Overseas Use
When corporate documents will be authenticated for use in another country, the physical seal does extra work. The apostille process, governed by the 1961 Hague Convention, verifies the authenticity of signatures and seals on the submitted document, which generally needs to be an original or certified copy. Placing the seal clearly and legibly near the signature keeps the authentication from stalling.
Getting a Clean Impression
A smudged or partial seal can prompt a recording office or foreign authority to reject the page, so the technique matters as much as the location.
With an embosser, feed the paper into the jaws so the seal will land where you want it, keep the paper flat against the plate, and squeeze firmly and evenly. If the paper shifts or bunches, the impression comes out incomplete. Thicker paper and cardstock need more pressure. Check the result immediately; every letter of the company name and the formation details should be legible.
With an ink stamp, start with fresh, even ink on the pad. Press straight down without rocking, hold for a moment, and lift straight up. Dragging or twisting smears the impression. Let the ink dry before stacking anything on top of the page.
Who Is Allowed to Affix the Seal
Placement is only valid if the right person is doing it. The corporation’s bylaws usually designate which officers can affix the seal, and that authority typically belongs to the corporate secretary, president, or another officer the board has specifically authorized. If someone without authority stamps a document, the corporation can later challenge whether it was properly executed. Store the seal securely and keep it accessible only to those officers.
When a Corporate Seal Is Actually Required
Most states no longer require one. The Revised Model Business Corporation Act, adopted in some form by most states, provides that corporate documents “may but need not contain a corporate seal, attestation, acknowledgment or verification.”2LexisNexis. Model Business Corporation Act 3rd Edition An authorized officer’s signature alone generally binds the corporation.
Seals still turn up in a few familiar situations:
- Real estate transactions, where some jurisdictions and recording offices expect a corporate seal on deeds and mortgages from entities.
- Third-party requirements from banks, lenders, and counterparties that want the seal on contracts, loan documents, or certifications as added verification.
- International dealings, especially documents headed for apostille certification or use in countries that still emphasize formalities.
- Internal corporate records such as stock certificates, bylaws, operating agreements, and certified resolutions, which commonly bear the seal even when not legally required.3Wolters Kluwer. The Benefits of Corporate Seals and Company Seals
Placing a Seal on Electronic Documents
You cannot press a raised impression into a PDF, so the “placement” question changes shape on electronic documents. The federal E-SIGN Act generally allows electronic signatures to satisfy legal signature requirements, and the Uniform Electronic Transactions Act, adopted in most states, follows the same principle. Agencies sometimes address the seal issue directly; the Bureau of Ocean Energy Management, for instance, lets corporations satisfy corporate seal requirements through a secure electronic filing system, provided the company first files a paper document bearing a physical seal that authorizes future electronic submissions.4eCFR. 30 CFR 556.107 – Corporate Seal Requirements
For routine business purposes, companies commonly insert a digital image of the seal into the signature block of the electronic document. For transactions that specifically require a physical seal, such as certain real estate recordings or apostille submissions, you will likely need to print the document, apply the physical seal next to the signature, and submit or scan the paper original.
Corporate Seal vs. Notary Seal
Adding a corporate seal does not satisfy a notarization requirement, and a notary seal does not stand in for a corporate seal. The corporate seal represents the corporation and signals that the document was executed with the company’s authority; the notary seal confirms that a notary public witnessed the signing and verified the signer’s identity. Many real estate documents call for both: the corporate seal near the officer’s signature to bind the company, and the notary seal on the acknowledgment to verify that the officer appeared and signed.
