A Medallion Signature Guarantee is a specialised form of authentication used primarily to verify signatures on certain financial documents. Though it originates from North America, it plays a crucial role for UK residents involved in cross-border transactions, particularly those linked to U.S. securities.
What Is a Medallion Signature Guarantee?
A Medallion Signature Guarantee confirms that the signature on a document is genuine and that the signer has the legal authority to carry out the action, such as transferring stocks, bonds, or other securities. It is not the same as a notarisation. It offers financial protection to the transfer agent processing the request, by providing a liability guarantee from the institution that issues it.
This guarantee typically involves stamping the document with a unique seal that includes a barcode or other form of traceable ID. The stamp comes from an authorised financial institution, such as a bank or investment firm, which must be part of a recognised signature guarantee programme.
When Is a Medallion Signature Guarantee Required?
UK residents most commonly require a Medallion Signature Guarantee when dealing with securities held in the United States. Typical scenarios include:
- Transferring shares from a deceased relative’s estate.
- Selling or gifting U.S.-based stocks.
- Changing the ownership of securities held in an investment account.
- Handling corporate share-related transactions.
These transactions often involve U.S. transfer agents who will not process changes without a Medallion Signature Guarantee to protect against fraud and unauthorised dealings.
Who Needs One in the UK?
Not everyone in the UK will need a Medallion Signature Guarantee, but it becomes necessary for:
- Heirs or executors managing estates that include U.S. stocks.
- Investors holding U.S. securities who wish to sell or transfer them.
- Shareholders needing to update personal details or account ownership linked to U.S. entities.
- Legal representatives acting on behalf of such individuals.
The key is whether the document in question relates to U.S. securities and requires validation by a U.S.-based transfer agent. If so, the Medallion Signature Guarantee is not optional—it’s mandatory. Getting one can take time, as only certain institutions can issue them, and the process involves verifying identity and legal authority. Anyone dealing with cross-border securities should understand when and why this guarantee is required to avoid delays or rejection of vital financial actions.

A Medallion Signature Guarantee is a special certification used in financial transactions to verify the authenticity of a signature and confirm that the person signing has the legal authority to do so. It is commonly required in the United States but may also affect international investors or account holders with financial ties to American institutions.
What Is a Medallion Signature Guarantee?
The Medallion Signature Guarantee is a stamp provided by authorised financial institutions such as banks, credit unions, or brokerage firms. It serves as a form of security against forgery in cases where ownership of securities—such as stocks, bonds, or mutual funds—is being transferred. Unlike a notary stamp, which merely verifies the identity of the signer, the Medallion Guarantee confirms both identity and legal capacity related to financial assets.
This system is governed by a set of rules enforced by financial industry groups in North America, ensuring that transfers of valuable securities are conducted safely and without fraud.
Procedure for Obtaining a Medallion Signature Guarantee
Getting a Medallion Signature Guarantee is not a simple walk-in process. It usually involves the following steps:
Contact the Institution
Not all financial institutions offer this service, and even those that do may restrict it to their clients. The first step is to confirm availability and eligibility requirements.
Prepare Your Documents
You will need to provide valid, government-issued photo identification and the documents involved in the transaction. These could include stock certificates, transfer forms, or letters of authorisation.
Demonstrate Legal Authority
If you are acting as a representative (such as an executor of an estate or a power of attorney), you must present documents that establish your authority to act on behalf of another individual or entity.
In-Person Verification
The institution will typically require an in-person appointment to witness your signature and verify your documents. Some institutions may charge a small fee.
Issuance of the Guarantee
Once approved, the institution will place the Medallion stamp near your signature on the relevant document. This stamp includes a unique barcode and ink colour that indicates the transaction value it covers.
When Is a Medallion Signature Guarantee Required?
This guarantee is required when transferring physical securities, changing the ownership of investment accounts, or making certain transactions involving financial instruments. Common scenarios include:
- Transferring stock certificates to another person or into a trust
- Selling or gifting physical securities
- Claiming shares of a deceased relative
- Changing the name on an investment account due to marriage or divorce
- Merging accounts under different names
Without a Medallion Signature Guarantee, these transactions cannot be processed, as financial institutions will not accept the risk of fraud or unauthorised activity.
Summary: While it is not widely used in domestic UK transactions, the Medallion Signature Guarantee is critical for individuals and professionals dealing with U.S.-related financial matters.
