Notaries working in banks or financial institutions may be asked to provide customers with a “Medallion Signature Guarantee.” Often mistakenly refereed to as a “Medallion Notary” or “Medallion Stamp”, this request is not a notarial act. It’s a special type of signature guarantee provided within the banking industry.
A Medallion Signature Guarantee is used primarily when a customer transfers or sells securities, and it represents an assurance by the financial institution that the signature on the transaction is genuine and the financial institution accepts liability for any forgery. These guarantees are performed by specially assigned bank employees.
If you are asked to provide any “Medallion” related services by a customer, explain that Medallion Signature Guarantees are not notarial acts and can only be performed by specially authorized bank personnel.
If a financial institution is not a member of a recognized Medallion Signature Guarantee Program, it would not be able to provide signature guarantees. Also, if a signer is not a customer of a participating financial institution, it is likely the financial institution will not guarantee the signature.
More information about Signature Guarantees is available on the U.S. Securities and Exchange Commission (SEC) website. Anyone who needs a signature guarantor should be directed to a commercial bank, savings bank, credit union, or broker dealer that participates in one of the Medallion Signature Guarantee programs.
