The Medallion signature guarantee is usually used in the transfer of securities—it aids in the prevention of fraud. It is the same idea behind the notary public—have a witness to confirm it is the person signing the document. But a normal notary public cannot complete these transactions for you—you cannot go to a notary public to complete an acknowledgement and think it has satisfied the requirement. An acknowledgment is not the same thing as a medallion guarantee. Financial institutions will be able to complete one for you. There are three programs for the certification of the Medallion signature guarantee, so ensure the institution participates in one of them. If they do not, they cannot offer you a signature guarantee. For a list of the Medallion Signature Programs and more information about the process, please visit the U.S. Securities and Exchange Commission’s website.
