Inherited US shares? Check the limit on your medallion stamp first

Your father’s died, and among the paperwork is a folder of US shares he bought years ago. You write to the transfer agent to sell or move them. Back comes a letter saying the form needs a medallion stamp, and your high street bank has never heard of it. That’s a very common story in UK estate work.

A medallion signature guarantee protects the transfer agent against forged or unauthorised transfers of North American stocks and shares. It’s used for estates, gifts of shares and sale instructions. And it’s hard to get outside North America, which is why so many executors get stuck on this one step.

The detail that catches people out is the value limit. Each guarantee carries a ceiling, and the transfer agent will reject a stamp that doesn’t cover the holding. On 10 August 2026, Lester Aldridge announced it had raised its own capacity to US$1,000,000, which tells you the market is moving towards higher-value holdings. Still, it’s only one provider, and limits differ from one to the next.

So do three things before you send anything. Work out the current market value of the holding in US dollars, not pounds. Ask the transfer agent, such as Computershare, what guarantee level it will accept. Then check that whoever provides your medallion stamp can cover that figure, because a rejected form can add weeks to an estate that’s already dragging.

If you’re stuck at this stage, Medallion Signature can explain what the transfer agent is asking for and what you’ll need to provide. Have a look at https://medallionsignature.co.uk/ or get in touch and ask before you post the forms.

Inherited US Shares? Why Getting Your Medallion Stamp Right First Time Matters in 2026

Sorting out a loved one’s estate is rarely simple, and it can throw up surprises even when you think you’ve seen every document in the file. One that catches a lot of…

Sorting out a loved one’s estate is rarely simple, and it can throw up surprises even when you think you’ve seen every document in the file. One that catches a lot of families out is discovering a shareholding with a US brokerage or transfer agent — and being told that before anything can be sold or transferred, they’ll need something called a Medallion Signature Guarantee, or ‘medallion stamp’.

It comes at a difficult time to be dealing with extra paperwork. UK probate is already taking longer than it used to: the number of cases stretching to 21–23 months has risen by 131% since 2021, and incomplete or inaccurate paperwork is now the single biggest reason applications get held up. Add in an overseas asset like US shares, and there’s real potential for a straightforward inheritance to drag on for months longer than it needs to.

A Medallion Signature Guarantee isn’t the same as a standard notarisation. It’s a formal certification, provided only by a small number of authorised guarantor institutions, confirming that the person signing a share transfer is genuinely who they say they are and has the legal authority to do so. Crucially, the guarantor institution takes on liability if the signature later turns out to be forged — which is exactly why US financial institutions insist on it for transfers, estate distributions and letters of transmittal.

Because so few UK firms are authorised to provide this stamp, getting it right the first time matters. An incorrectly completed or improperly witnessed guarantee can be rejected by the US institution, sending the whole process back to square one and adding weeks to a probate timeline that may already be under strain.

If you’ve come across a US shareholding while administering an estate and aren’t sure what to do next, it’s worth speaking to specialists who handle this every day. Fraser and Fraser’s Medallion Signature Guarantee service is one of the few in the UK authorised to issue the stamp, for transactions of up to $1,000,000 — find out more at medallionsignature.co.uk/.

Medallion Stamp Explained: What UK Shareholders Need to Know About Medallion Signature Guarantees

Document signing and certification process for a Medallion Signature Guarantee

It’s a scenario more UK shareholders are running into: you go to sell or transfer shares you’ve held for years, only to be told the company was bought out by a US or Canadian firm a while back, and that you now need something called a Medallion Signature Guarantee before the transfer can go ahead. It sounds obscure, but it’s becoming a more common hurdle as cross-border takeovers of UK-listed companies continue.

A Medallion Signature Guarantee, or MSG, is a certification confirming that the signature authorising a securities transaction is genuine and that the person signing has the legal authority to do so. It’s required whenever UK, European or other overseas holders deal with US or Canadian securities, whether that’s selling shares, transferring them, or updating the name on the holding. Well-known examples include Cadbury, taken over by Kraft in 2010, and Vodafone’s sale of its Verizon Wireless stake to Verizon Communications in 2013 — both left UK shareholders needing an MSG to act on their holdings.

The catch for UK residents is that only members of a Medallion Signature Guarantee programme can actually issue one — typically banks, trust companies and brokers based in the US or Canada. That leaves people outside North America in a difficult spot, since most of their own bank or broker simply can’t provide the stamp, however well they know their customer.

It’s also worth knowing an MSG isn’t the same as a notarised document, and one can’t be substituted for the other. The difference comes down to liability: a firm issuing a Medallion Signature Guarantee is on the hook if the signature turns out to be forged, which is precisely why the process exists and why so few organisations outside North America are authorised to provide it.

Fraser and Fraser is one of the few firms in the UK holding its own Medallion Signature Guarantee stamp, able to certify transactions of up to US$1,000,000 for clients across the UK, Europe, Australia and New Zealand.

Passing US Shares to Your Family? Why You’ll Likely Need a Medallion Signature Guarantee

Medallion Signature Guarantee service for transferring US and Canadian shares

More and more people in the UK are choosing to pass on shares to their children or grandchildren while they are still around to see them enjoyed. It is a lovely idea — but if any of those shares are held in an American or Canadian company, there is one small piece of paperwork that catches almost everyone out: the medallion signature guarantee.

In plain terms, it is a special stamp that US and Canadian registrars insist on before they will move shares from one person to another. It confirms your signature is genuine and that you are entitled to make the transfer. Crucially, it is not the same as a solicitor’s certification or a notary stamp — send those instead and the transfer will simply be refused, often after weeks of waiting.

The frustrating part for UK residents is that very few places over here are actually authorised to provide the guarantee. People commonly spend weeks posting original certificates back and forth and chasing banks, only to be turned away. When you are simply trying to do something generous for your family, that runs the joy out of it very quickly.

It really does not have to be that hard. With the right paperwork in place — usually proof of identity and clear evidence of ownership — the guarantee can be arranged correctly the first time, so the shares move smoothly and your gift arrives without months of delay.

If you are thinking of gifting, selling or transferring US or Canadian shares, the team behind Medallion Signature Guarantee can explain exactly what you need and handle it properly for you. Find out more at medallionsignature.co.uk/.

Medallion Signature Guarantee service for transferring US and Canadian shares

Sorting out a loved one’s estate is hard enough without hitting an unexpected hurdle. Yet time and again, families in the UK discover that Grandad quietly held shares in an American or Canadian company – and that selling or transferring them is nowhere near as simple as they hoped. If that sounds familiar, you have almost certainly come across the words “medallion signature guarantee”.

So what is it? In short, it is a special stamp that US and Canadian financial institutions insist on before they will allow overseas shares to be transferred or sold. It confirms that your signature is genuine and that you have the authority to act. It is not the same as a solicitor’s certification or a notary stamp, and this is where a lot of people get caught out – the American registrar will simply reject anything else.

The tricky part for UK residents is that very few places over here are actually authorised to provide the guarantee. People often spend weeks going back and forth with banks and registrars, sending original share certificates across the Atlantic, before they find the right service. In the middle of dealing with probate, that is the last thing anyone needs.

The good news is that it does not have to be complicated. With the correct paperwork – usually proof of identity, evidence of ownership and, where relevant, grant of probate – the guarantee can be arranged properly the first time, saving you the delays and posted certificates that cause so much worry.

Why the Medallion Signature Guarantee Matters More Than Ever as US Buyers Eye UK Companies

If you hold shares in a UK-listed company, there’s a good chance you’ve been paying closer attention to the financial news lately. The volume of cross-border takeovers has been rising sharply, with…

Medallion Signature Guarantee stamp for US securities transfers

If you hold shares in a UK-listed company, there’s a good chance you’ve been paying closer attention to the financial news lately. The volume of cross-border takeovers has been rising sharply, with US private equity and strategic buyers accounting for a significant and growing share of UK acquisitions. For ordinary shareholders, these deals often come with an unexpected consequence: your UK shares can become US securities overnight — and that changes everything about how you access or transfer them.

When a UK company is acquired by a US buyer, shareholders who want to sell, transfer, or update their holdings in the new entity will typically encounter a requirement they’ve never come across before: the Medallion Signature Guarantee. This is a specialist certification — only available from a small number of authorised institutions — that verifies the authenticity of a signature on securities transfer documents. It’s a mandatory requirement for most US and Canadian share transfers, and without it, your assets can be effectively frozen.

The Medallion Signature Guarantee isn’t a notary stamp and it isn’t something your high street bank can provide. It requires a certified guarantor who is a member of an approved Medallion programme, with the financial capacity to back the guarantee. The stamp confirms both that the signature is genuine and that the signer has the legal authority to transfer the securities in question.

This is particularly relevant for estate executors, solicitors, and beneficiaries dealing with inherited holdings in US or Canadian companies. Whether you’re managing shares in a long-established US brand or dealing with the aftermath of a takeover, getting the right documentation in place early can save significant time and cost — delays in this area can mean frozen capital at exactly the wrong moment.
