A Medallion Signature Guarantee is:
- A signature authentication method used to ensure that documents related to the ownership of securities are legitimate. At Capital One Investing, a Medallion Signature Guarantee is most commonly required when requesting a transfer of assets from Capital One Investing to another brokerage.
- The signature guarantee process makes it harder for someone to take your assets by forging your signature on documents
- A Medallion imprint or stamp indicates that a financial institution is a member of a Medallion Signature Guarantee program and is an acceptable signature guarantor
- They're commonplace at savings & loan associations, commercial banks, and credit unions (most of which don't charge their customers for the service)
Tip: Call ahead of time and ask what forms of identification (birth certificate, driver's license, a well-timed smile, etc.) the savings & loan association, bank, or credit union requires.
