Medallion Guarantee vs Notary - What’s the Difference and Why It Matters

When it comes to verifying financial documents, two terms often surface: Medallion Guarantee and Notary. Although both provide validation, they serve different purposes and are recognised in distinct situations. The best part before proceeding is to understand the differences. This will be essential, especially when dealing with investments, share transfers, or important legal paperwork.

What Is a Medallion Guarantee?

A Medallion Guarantee is a specialised certification used mainly for the transfer of securities such as shares, bonds, or mutual funds. It is issued by financial institutions that are part of recognised Medallion programmes.

This guarantee confirms that the signature on a securities-related document is genuine and that the institution backs the financial value involved. It protects investors and organisations against fraud, making it a critical step when completing high-value transactions. Unlike common verification methods, it requires strict identity checks, institutional approval, and specialised training.

What Does a Notary Do?

A notary public verifies identities, witnesses signatures, and confirms that documents are signed willingly. Notarisation is used for general legal papers such as affidavits, property agreements, declarations, and powers of attorney.

However, a notary cannot certify transactions involving securities. Their role is to prevent document-related fraud but does not extend to guaranteeing financial liability. This distinction is where many individuals become confused.

Key Differences and Why It Matters

The biggest difference lies in purpose and level of assurance. A notary confirms your identity, while a Medallion Guarantee confirms both your identity and the financial risk associated with the document.

If you are transferring stocks or handling assets held with brokers or registrars, you will almost always need a Medallion Guarantee—not a notary stamp.

Using the wrong certification can delay transactions or even result in rejection, costing time and effort.
