A Medallion Signature Guarantee is a specialised certification required primarily for financial transactions involving securities in the United States. While it is commonly used in the U.S., individuals and businesses in the United Kingdom may also need this guarantee when transferring or selling U.S.-based assets such as stocks, bonds, or mutual funds. This guarantee is provided by authorised financial institutions and serves as a safeguard against fraud, ensuring the authenticity of the signature on important financial documents.

When Is a Medallion Signature Guarantee Required?

A Medallion Signature Guarantee is typically required in situations where financial assets registered in the United States are being transferred, sold, or inherited by a party outside the country. Some of the common scenarios where a Medallion Signature Guarantee is needed include:

Transferring or Selling Securities – If a UK-based investor owns U.S. stocks or bonds and wishes to sell or transfer them, the transfer agent handling the transaction will usually require this signature guarantee to authenticate the request.

Inheritance and Probate Matters – When a UK resident inherits U.S. securities from a deceased relative, they must obtain this Signature Guarantee to transfer ownership of those assets. This is particularly necessary when dealing with financial institutions that require identity verification.

Changing Account Ownership – If a person wishes to transfer securities to another individual, whether due to gifting, marriage, or legal agreements, Medallion Signature Guarantee is often needed to complete the transaction securely.

Merging or Changing Business Ownership – If a UK-based company has investments in the U.S. and undergoes structural changes such as mergers or ownership transfers, this signature guarantee is required to validate the process.

What Is the Role of a Medallion Signature Guarantee?

The primary role of a Medallion Signature Guarantee is to verify the authenticity of a signature on financial documents. This helps prevent fraudulent transactions by ensuring that only the rightful owner can authorise changes to their financial holdings. Unlike a regular notarisation, this process comes with a financial liability guarantee from the institution providing it, meaning the institution confirms the validity of the signature and assumes responsibility for any fraudulent transactions.

Medallion Signature Guarantee is different from a standard notary service in the UK. While a notary public verifies signatures for legal purposes, the guarantee is specific to securities transactions and involves stringent verification checks. Only select financial institutions, such as banks, credit unions, and brokerage firms, are authorised to provide this guarantee.
