The main alternatives to a Medallion Signature Guarantee are a transfer agent’s small-account waiver, a notarized signature for non-ownership changes, a Signature Validation Program (SVP) stamp for certain fund movements, and estate documents such as a small estate affidavit or letters testamentary after a death. If you hold your investments in a brokerage account rather than as physical certificates in your own name, the requirement usually doesn’t come up at all. Which alternative works depends on what you’re trying to do and how much the securities are worth.
Why the Stamp Is So Hard to Get
Federal rules limit which institutions can provide a Medallion Signature Guarantee. Under SEC Rule 17Ad-15, transfer agents may only accept guarantees from “eligible guarantor institutions” that belong to a recognized signature guarantee program.1eCFR. 17 CFR 240.17Ad-15 – Signature Guarantees Those are banks, broker-dealers, credit unions, and savings associations that participate in STAMP, SEMP, or MSP.
Not every bank or credit union participates, and those that do generally guarantee signatures only for their own established customers. If you don’t bank with a participating institution, you can spend days calling around with nothing to show for it. That’s the wall that sends most people looking for a workaround.
Transfer Agent Waivers for Small Accounts
When the securities you’re moving are worth a modest amount, many transfer agents let you skip the Medallion requirement through a formal waiver. Computershare, one of the largest U.S. transfer agents, runs a waiver program for accounts valued under $10,000 with a flat $50 processing fee paid by check.2Computershare. What Is a Medallion Guarantee Other transfer agents set different thresholds and fees, so check with yours directly.
To apply, complete the transfer agent’s waiver or transfer request form with the share quantities, current market value based on the most recent closing price, and account numbers. Include a copy of your government-issued photo ID. Submit the package by certified mail for tracking, or use the agent’s secure upload portal if one exists.
If the waiver is granted, the agent processes the transfer and sends confirmation. If denied, you’ll get a letter explaining why, usually because the account value exceeded the threshold or documentation was incomplete. Missing one required field tends to trigger an outright rejection rather than a follow-up call, so check everything before sending. These waiver programs exist at each transfer agent’s discretion; the SEC declined to create a federal safe harbor based on dollar thresholds when it finalized Rule 17Ad-15.3Securities and Exchange Commission.

Notarized Signatures for Non-Transfer Changes
A notary public is often enough when you aren’t actually changing who owns the securities. Updating a mailing address, correcting your name after a marriage, or changing a beneficiary designation on a non-probate account are administrative updates, not ownership transfers. Transfer agents and brokerages routinely accept a notarized signature for this kind of paperwork. Notary fees across most states run between $2 and $25 per signature.
A notary won’t work for an actual ownership transfer. A Medallion guarantor accepts financial responsibility if your signature turns out to be forged; a notary only confirms that a person appeared in person, showed valid ID, and signed. Transfer agents are specifically allowed under SEC rules to reject a transfer request when the guarantor doesn’t participate in a signature guarantee program,1eCFR. 17 CFR 240.17Ad-15 – Signature Guarantees and a notary isn’t a guarantor at all.
The Signature Validation Program
The Signature Validation Program (SVP) sits alongside the Medallion programs but covers different transactions. Financial institutions use SVP stamps for movements that don’t involve transferring ownership of publicly traded securities: retirement account distributions, health savings account movements, and certain internal fund transfers. Because these carry lower risk, the SVP provides a lighter verification layer than a full Medallion guarantee.
Banks and credit unions that don’t participate in STAMP, SEMP, or MSP may still participate in SVP, so it’s often available where a Medallion guarantee is not. The SVP stamp verifies the signature matches what the institution has on file, but doesn’t carry the same indemnity coverage. Transfer agents recognize SVP stamps for document types that fall outside strict securities ownership transfers. If your transaction involves moving funds rather than transferring stock ownership, ask your bank whether it can provide an SVP stamp.
Holding Securities Through a Brokerage
The simplest way to sidestep the Medallion requirement is to avoid the situation that triggers it. Physical stock certificates registered directly in your name force you to endorse the certificate and get that endorsement guaranteed whenever you want to sell or transfer. When your investments sit in a brokerage account in “street name,” the brokerage is the registered owner on the transfer agent’s books and you’re the beneficial owner. The brokerage handles sales, transfers, and re-registrations internally, with no Medallion stamp needed from you.4Investor.gov. Transferring Assets
If you currently hold physical certificates, you can deposit them into a brokerage account and have the shares re-registered in the brokerage’s name with you as beneficial owner. That initial deposit may itself require a signature guarantee, so this approach works best as a preventive step before you actually need to make a transfer.
Transferring Securities After a Death
Inherited securities are one of the most common situations where people run into the Medallion wall. State law governs how ownership passes after death, so the exact requirements depend on where the deceased lived and how the account was set up.4Investor.gov. Transferring Assets
Transfer on Death Registration
If the deceased set up Transfer on Death (TOD) registration on the account, the named beneficiaries can typically re-register the securities by submitting a death certificate and a re-registration application to the transfer agent.4Investor.gov. Transferring Assets Some transfer agents handle TOD transfers without requiring a Medallion guarantee, particularly for lower-value accounts or when the beneficiary can appear in person.
Small Estate Affidavits
For accounts without TOD registration, options depend on the estate’s size. Every state offers a simplified process for settling small estates, typically through an affidavit rather than full probate. The dollar thresholds for qualification range from roughly $10,000 to $275,000 depending on the state, with most falling between $50,000 and $100,000. If the estate qualifies, a small estate affidavit combined with a certified death certificate and letters of authority may satisfy the transfer agent without a Medallion guarantee. Whether this works depends on the transfer agent’s internal policies, so call their shareholder services line before assembling the paperwork.
Probate Documents
Larger estates going through formal probate produce court-issued letters testamentary or letters of administration. Transfer agents generally accept these along with a certified death certificate to re-register securities. A Medallion guarantee on the executor’s signature may still be required for high-value accounts, but the transfer agent’s waiver program may apply if the securities fall under the dollar threshold. Contact the transfer agent early in the probate process to find out exactly what they need; each agent has its own checklist.
Options for Investors Outside the United States
Living abroad makes this harder because the eligible guarantor institutions are overwhelmingly domestic. Start by checking whether any U.S. bank with international branches operates near you. Some foreign branches of major U.S. banks can provide Medallion guarantees to existing customers. If none is accessible, ask your local financial institution whether it has a correspondent banking relationship with a U.S. institution that participates in a Medallion program.
U.S. embassies and consulates offer notarial services similar to a domestic notary. A consular officer can witness your signature and verify your identity, but that’s identity verification, not a financial guarantee. Whether a transfer agent will accept consular authentication in place of a Medallion guarantee depends on the agent’s policies and the transaction’s size. For smaller transfers, especially those within a waiver program’s threshold, consular authentication combined with the other required documentation may be enough.
In countries that participate in the Hague Apostille Convention, adding an apostille to a notarized document provides an extra layer of authentication verifying that the notary’s signature and seal are legitimate under that country’s laws. Some transfer agents accept apostilled documents for certain transactions, though acceptance is not universal. Contact your transfer agent before starting the apostille process to confirm they will accept it.
Expect the Alternative Route to Take Longer
A standard transfer submitted with a proper Medallion guarantee has to be processed quickly: federal rules require transfer agents to process at least 90% of routine items within three business days. Transfers submitted with alternative documentation are classified as non-routine, and the only federal requirement is that non-routine items receive “diligent and continuous attention” and be completed “as soon as possible.”5eCFR. 17 CFR 240.17Ad-2 – Turnaround, Processing, and Forwarding of Items
In practice, waiver applications and non-standard submissions can take anywhere from five business days to several weeks. If you’re trying to sell during a volatile market, that delay carries real financial consequences. Transfer agents are not generally liable for market losses that occur while they review non-standard paperwork, and the SEC has considered but not adopted rules requiring agents to buy in securities when transfer instructions sit unprocessed too long.6Federal Register. Transfer Agent Regulations If you know you’ll need to transfer securities, start the paperwork well before you need the transaction to close.
