Medallion stamps and notary stamps are frequently confused, despite being fundamentally different instruments. Not only are they different in shape, size, color and type of ink but they also serve very different functions and have distinct liability scopes.
The core distinction: signature guarantees apply to financial documents and securities transfers, while notary stamps are used for legal documents.
What Notary Publics Do
Notary publics are state-appointed impartial witnesses designed to prevent fraud during document signing. Their responsibilities include:
- Verifying the signer’s identity
- Ensuring the person isn’t being coerced
- Confirming document comprehension
- Administering oaths when necessary
Common transactions requiring notarization involve home purchases, vehicle transfers, power of attorney documents, and travel consent authorizations.
Medallion Signature Guarantees Explained
These specialized guarantees are used specifically for securities transfers in the United States. The guaranteeing financial institution accepts liability for signature authenticity and any resulting forgery losses, protecting shareholders and limiting transfer agent liability.
The Supply Challenge
Banks increasingly avoid providing medallion guarantees due to liability concerns. Many institutions refuse transactions exceeding $100,000 or involving corporate entities, trusts, or estates—yet these scenarios still require the guarantee.
