How to sign and witness a UK will overseas

The most carefully drafted will in the world can be undone in the time it takes to sign it. English law's execution rules date from 1837 and they are unforgiving: get the witnessing wrong and the will is invalid, which means your estate falls back to an earlier will or to the intestacy rules, as if the document you paid for and meant every word of had never existed. Practitioners who deal with failed DIY wills see bad witnessing again and again, and probate disputes are climbing: probate claims in the High Court's Chancery Division rose by 13% in 2025, according to Solomonic's litigation data.

For British expats the rules are the same as they'd be in Surrey, which is precisely the good news. No embassy appointment, no notary's seal, no special overseas procedure. A will signed correctly in Da Nang or Dubai is exactly as valid as one signed in Doncaster. What trips expats up is the folklore that has grown up around the law, so let's do the rules first and the folklore second.

The four requirements

Under section 9 of the Wills Act 1837, a will is valid only if: it is in writing; it is signed by the testator, the person making the will, or by someone signing at their direction and in their presence; the testator's signature is made, or acknowledged, in the presence of two or more witnesses who are present at the same time; and each witness then signs, or acknowledges their signature, in the presence of the testator. The testator must intend the signature to give effect to the will.

Read the third requirement again, because it is the one that kills wills: both witnesses, together, at the same moment, when you sign or acknowledge your signature. A witness who arrives later and signs on the strength of "yes, that's my signature from this morning" is fine only if you acknowledge the signature afresh with both of them there. The witnesses do not have to sign in each other's presence, but they must each sign in yours. The tidy way to honour all of this is to run one clean ceremony.

Who can witness, anywhere on earth

Here is the liberating part for expats: the law imposes no nationality, residence or language requirement on witnesses. Your Spanish neighbour, your Vietnamese colleague, the couple next door in Dubai, all are as legally capable of witnessing your will as anyone in England. Witnesses attest your signature, not your secrets: they do not need to read the will or know what's in it.

The real rules are these. Use two adults with their wits about them; a witness must be able to see the act of signing, which is why a blind person cannot witness, and should be someone capable of giving evidence about it one day. Never use a beneficiary, or the spouse or civil partner of one: the will survives, but the gift to that person is void, a rule that has quietly disinherited more than one family member who helpfully stepped in as a witness. Executors can witness if they take nothing under the will. And have each witness print their full name, address and occupation beneath their signature, because if the probate registry ever doubts the execution, it will want a statement from someone who was in the room, and a signature with no name attached is a dead end.

The ceremony, done properly

One room, one sitting, one document. You sign first, in full view of both witnesses, with nothing covering the page. Each witness then signs while you watch. Nobody leaves until all three signatures are on the will. Date it, not because the statute demands a date, but because an undated will invites the registry to start asking questions. Then stop touching it: alterations made after execution are ineffective unless they are themselves signed and witnessed like the will, so a helpful biro correction the following week can unravel a clause.

A well-drafted will ends with an attestation clause, a short paragraph reciting that the formalities were followed. It isn't legally required, but it earns the will a presumption of due execution, which usually means a foreign-signed will with a proper attestation clause passes through probate without anyone asking your witnesses in Hanoi to swear statements.

The folklore, corrected

The embassy will witness it. No. British embassies and consulates witness signatures only in exceptional circumstances, and the FCDO's guidance points you to local notaries and lawyers instead. You do not need officialdom anyway: any two qualifying adults suffice.

We did it over Zoom in lockdown, so that still works. It doesn't. The temporary law that let "presence" include video ran for wills made between 31 January 2020 and 31 January 2024, and the government chose not to extend it. Wills validly video-witnessed inside that window remain valid; new ones must be witnessed in physical presence.

I'll sign my copy here and my witnesses will sign theirs in England. Counterpart execution is not valid for wills. Everyone signs the same physical document. If your witnesses are on another continent, the fix is two witnesses on your continent, not a courier.

It needs to be notarised or registered somewhere. It doesn't. An English will requires no notary, no stamp, and no registration to be valid; will registration services are useful and entirely voluntary. If you sign before a notary abroad because local practice expects it, the notarisation adds nothing in England, and any extra stamps, seals or attached certificates on the original can prompt probate queries, so keep the English will's execution plain.

One more route worth knowing exists: a will executed in local form abroad, say before a French notaire, can still be formally valid in England under the Wills Act 1963, which accepts execution that complies with the law of the place of signing, your domicile, habitual residence or nationality. Treat it as a fallback. A section 9 execution is recognised without foreign-law evidence, while proving a foreign-form will means a paper probate application, evidence of the foreign law, and certified translations. Do it the English way and the question never arises.

Guard the original like it's the estate

English probate runs on the original will; a photocopy will not be accepted, and if the original was last known to be in your possession and cannot be found, the law presumes you destroyed it intending revocation. That presumption can be rebutted, but only with evidence, assembled by your family after you are gone. So think carefully before entrusting the only executed original to an international courier, and think about where it lives: with your solicitor or will provider in the UK, in the official storage service run by the probate service for a small fee, or somewhere at home your executors actually know about. Wherever it is, tell your executors, and keep a copy with a note of where the original sits.

What to do now

1. Line up two witnesses who take nothing under the will, and aren't married to anyone who does. Neighbours and colleagues are ideal; family members who inherit are the classic mistake.
2. Run the ceremony in one sitting: you sign first in full view, witnesses sign while you watch, nobody leaves, date it, and have the witnesses add names, addresses and occupations.
3. Leave the document alone afterwards. Changes mean a new will or a properly executed codicil, not a pen.
4. Decide where the original lives and tell your executors. An unfindable will fails almost as thoroughly as an unsigned one.
5. If you signed a will by video between 2020 and early 2024, it stands, but if anything material has changed since, replace it with a conventionally witnessed one and remove the doubt.

An Expat Legacy will arrives with plain-English signing instructions written for exactly this ceremony, and every will is reviewed by a person before your documents are released: £149 for a single will, £249 for mirror wills for a couple. The drafting is our job. The last ninety seconds are yours, and now you know how to run them.
