Medallion Signature Guarantee

A Medallion Signature Guarantee is a specialized stamp of authentication that validates the transfer of financial securities like stocks and bonds in physical form. This guarantee protects against fraud and ensures the legitimacy of securities transactions by verifying the identity of the person transferring ownership.

Key Concepts

A medallion signature guarantee is a validation certifying the legitimacy of the transfer of financial securities in physical form to another person. Financial institutions and transfer agents require it to defend against fraud and confirm the authenticity of the transactions.

To obtain a medallion signature guarantee, the respective financial institution must be participating in a medallion signature guarantee program. Banks, credit unions, and brokerage firms issue this authorization stamp after completing a stringent verification process.

How Medallion Signature Guarantee Works

The process requires you to have an account with a financial institution authorized to provide this service. You must present the document in person with government-issued photo identification and proof of ownership of the securities being transferred.

The financial institution will verify your identity, confirm that you are authorized to sign the document, and ensure your signature matches the one on file. If everything checks out, they will add a medallion signature guarantee stamp to the document, allowing the transaction to proceed with security and confidence.
