What is a Signature Guarantee?

A signature guarantee is different than a notary stamp because it guarantees and protects transfer agents and corporate stock issuers against fraudulent transactions. Some financial institutions that provide signature guarantees are stock brokerage firms, banks, and credit unions. A stock transfer agent cannot accept a stock certificate for transfer without a signature guarantee unless the certificate is being transferred into the exact same name.

Why You Need a Signature Guarantee?

A signature guarantee helps protect people involved in paper-based stock transactions from fraud.

You will need a signature guarantee when you go to sell physical stock certificates, to prove to the securities transfer agent that you are who you say you are, and that you have the right to sign over the rights to the assets you're selling. You may also need a signature guarantee if you're gifting shares or changing ownership on an investment account.

A Signature Guarantee protects:

  • You as an existing shareholder, by making it less worthwhile for someone to steal your physical shares to try to cash in on them.
  • The transfer agent, whose liability is reduced by the signature guarantee.
  • You as a purchaser of someone else's shares, by providing a guarantee that you're purchasing legitimate shares of stock from someone who has the right to sell them to you.

Is my credit card information safe?

We do not store/save any credit card information within our systems. Our secure/encrypted gateway sends the information directly to our PCI Compliant billing partner.

Do I need to send my stock certificate and, if so, how should I send it to you?

As part of our process, after your identification has been verified, you will be given the option to work with us via “digital signatures” in which case you can upload documents to us OR you can send us “pen to paper” signatures in which case we will provide you a link to print a prepaid Fedex label to send us a package with your originally signed documents and your stock certificate. After we stamp your document with our signature guarantee, we will Fedex the certificate back to you or your transfer agent, as instructed by you.

Where will you send the document with the Signature Guarantee?

We will send it via courier wherever you instruct us to. Most clients either have us return it to the original sender or, to save time and money, will instruct us to send the document (with the completed signature guarantee) directly to their stock transfer agent for further processing.

Which Transfer Agents accept your medallion signature guarantee?

Great question! – All of them would (and do) accept our medallion signature guarantee since our guarantee is the same type as provided by other banks and financial institutions.

Can I get a medallion signature guarantee on a 401K document, annuities transfer form or other items other than a stock certificate?

Yes! We can work with most documents related to securities such as funds transfer, 401k paperwork, annuities, brokerage account forms, etc. We can also work with you regardless if your stock is publicly traded or is privately held.

I understand that I can get a medallion signature guarantee on a physical certificate, but can you help me if I own my shares in electronic format held at the transfer agent?

Yes – great question! We can provide you with a signature guarantee for either process. We can provide a signature guarantee on a physical certificate, transfer agent form or stock power to indicate ownership held in electronic format at the stock transfer agent.

Our fee is $149 per medallion stamp needed.

What if I own my stock as a corporate entity?

No problem. Once you log in, you will see an option to proceed as an entity, corporation, trustee or executor. Just follow the directions.

A family member is deceased, can you still process a medallion stamp?

We are sorry to hear of your loss. Yes, we can assist. If the shareholder is deceased, we would need to verify the signature of the Executor or Trustee. We would need documents such as Letters Testamentary, certified copy of the death certificate and copy of executor's driver's license.

What is the value limit of the medallion guarantee that you provide?


What do you mean when you say I can provide you with a “digital” or “electronic” signature?

According to the U.S. Federal ESIGN Act passed in 2000, an electronic signature is an "electronic sound, symbol, or process, attached to or logically associated with a contract or other record and executed or adopted by a person with the intent to sign the record."

Can I provide eSignatureGuarantee.com with an electronic signature on my stock power?

You should check with your financial institution if they will accept a digital signature. We have added a Stock Power template to our platform that will allow you to download a generic stock power, complete it on your screen, sign it electronically and then submit it to us for a physical medallion signature guarantee which we will Fedex as you instruct us to. The Securities Transfer Association in their guidelines have stated that an electronic signature on the transfer instructions are acceptable if the medallion signature guarantee on such instruction is an original; provided, however, if the transaction is valued at over $14 million, the STA recommends requiring the transfer instruction and signature to be an original. Some annuities, insurance companies or other financial institutions may have internal policies that require “pen to paper” signatures so please consult with them as such.
