Who Can Witness a Will in the UK — Rules, Requirements & Common Mistakes

You've drafted your will. Now you need to sign it in front of witnesses — and this is where a significant number of wills are invalidated. Not because the document itself is wrong, but because the witnessing ceremony wasn't done correctly. This guide covers who can witness a will in England & Wales, Scotland, and Northern Ireland, who is disqualified, and the mistakes that cost beneficiaries their inheritance.

The Short Answer: Who Can Witness a Will in England & Wales

Any adult who meets all three of these conditions can witness a will in England and Wales:

1. Aged 18 or over — minors cannot act as witnesses
2. Of sound mind — mentally capable of understanding what they are witnessing
3. Not a beneficiary under the will — and not the spouse or civil partner of a beneficiary

Two witnesses are required, both physically present at the same time when the testator (the person making the will) signs. The legal authority is section 9 of the Wills Act 1837, as amended by the Administration of Justice Act 1982.

The witness does not need to be a solicitor, a professional, or any particular type of person. A neighbour, a colleague, a friend — all are entirely valid. What matters is that they are independent adults with no financial stake in the will.

Who CANNOT Witness a Will

The following people are disqualified from acting as witnesses, or their involvement has serious legal consequences:

Beneficiaries — and Their Spouses or Civil Partners

This is the most important rule and the source of the most common witnessing error. Under section 15 of the Wills Act 1837, if a witness (or their spouse or civil partner at the date of signing) is also a beneficiary under the will, that beneficiary's gift is voided. The will itself remains valid — it does not invalidate the entire document — but the witness-beneficiary loses their inheritance entirely.

The same rule applies to the spouse or civil partner of a witness: if your witness is married to someone who stands to inherit under your will, that beneficiary's gift is at risk, even if the beneficiary themselves never touched a pen.

Critically, this restriction applies at the date of signing. If your witness later marries a beneficiary, the gift is not retrospectively voided. The point of assessment is the moment of execution.

Blind Persons

A witness must be capable of seeing the testator sign. A person who is blind or has such severely impaired vision that they cannot observe the signing cannot act as a witness under English law.

The Testator Themselves

You cannot witness your own will. The testator signs as the maker of the document; the witnesses are there to attest that the testator did indeed sign it. These are legally distinct roles.

Minors

A person under 18 cannot act as a witness to a will in England and Wales. Even if a minor is present and physically capable of signing, using them as a witness creates a defect in execution that may render the will invalid.

Common Witnessing Mistakes

These are the errors that cause wills to be challenged or gifts to be voided:

Using only one witness. English law requires two. A will signed in front of only one witness is not validly executed and is legally void.

Witnesses signing at different times. Both witnesses must be present simultaneously when the testator signs, and both must sign in the testator's presence. If witness one leaves the room before witness two arrives, the execution is defective.

A beneficiary acting as witness. By far the most common error in DIY wills. The gift to the beneficiary-witness is voided under s.15 — even if the will was otherwise perfectly drafted. A child who witnesses a parent's will loses their inheritance.

The testator not signing in the witnesses' presence. The testator must sign (or acknowledge a prior signature) while both witnesses are physically present. Signing beforehand and asking witnesses to countersign later is not valid execution.

Using a minor as a witness. As noted above, a person under 18 cannot be a valid witness regardless of their apparent maturity.

Not completing the witness section. Each witness should sign their name and add their name, address, and occupation in the attestation clause. While the absence of address details does not technically invalidate the will, it creates evidential difficulties if the execution is ever challenged in court.

Step-by-Step: How to Properly Witness a Will

The execution ceremony is simpler than people make it. Follow this sequence precisely:

1. All three people must be present. The testator and both witnesses must be in the same room at the same time before anything is signed.
2. The testator signs first. Sign (or initial each page, and sign the last page) while both witnesses watch. Use a permanent pen.
3. Each witness signs in turn, in the testator's presence. Both witnesses must sign while the testator (and ideally the other witness) can see them. One at a time is fine; what matters is that the testator is present for both signings.
4. All on the same physical document. Everyone signs the original paper will at the same session. You cannot use copies, separate sheets, or electronic documents.
5. Complete the attestation clause. Each witness should add their full name, address, and occupation beneath their signature. This provides evidence of identity if the will is ever challenged.

Do not use correction fluid, sticky tape over corrections, or any alteration to the signed document. If you spot an error after signing, the safest remedy is to reprint the entire will and repeat the ceremony from scratch. Alterations made after execution are not legally part of the will unless re-executed with full formality.

Can a Family Member Witness a Will?

Yes — provided they are not a beneficiary and not the spouse or civil partner of a beneficiary.

This confuses many people because the restriction is not about family relationship — it is about financial interest. A sibling who receives nothing under your will can validly witness it. A best friend who is named as a beneficiary cannot.

Common scenarios:

• Adult child who is a beneficiary — cannot witness. Their gift would be voided.
• Adult child who receives nothing under the will — can witness, despite being family.
• Sibling named as executor but not as a beneficiary — executors with no beneficial interest can witness.
• Neighbour with no connection to the estate — ideal witness. No interest, no risk.

The practical guidance: pick two people who are clearly independent of the estate. Neighbours, work colleagues, or friends who are not mentioned in the will are the safest choices.

Remote Witnessing — Is It Still Allowed?

Briefly, during the COVID-19 pandemic, the UK government introduced the Wills Act 1837 (Electronic Communications) (Amendment) (Coronavirus) Order 2020, which permitted wills to be witnessed via video link under strict conditions. This was extended and remained in force until 31 January 2024.

From 1 February 2024, remote witnessing is no longer valid in England and Wales. Wills must once again be executed in person, with all parties physically present in the same location.

The Law Commission is currently reviewing will-making formalities as part of a broader modernisation project, and remote or electronic witnessing may be permanently legislated in future. For now, however, the rule is unambiguous: in-person only.

Video witnessing is not valid in the UK as of 2026. A will witnessed over Zoom, FaceTime, or any video platform after 31 January 2024 is not validly executed.

Scotland: Significantly Different Rules

Scotland operates under the Requirements of Writing (Scotland) Act 1995, not the Wills Act 1837. The differences are substantial:

Rule	England & Wales	Scotland
Number of witnesses required	Two	One
Must witness the act of signing?	Yes — present when testator signs	No — can acknowledge prior signature
Beneficiary restriction	Beneficiary loses gift if they witness	No restriction — beneficiaries can witness
Minimum witness age	18	16
Holograph wills (no witness)	Not valid	Valid if entirely handwritten and signed

The beneficiary point is the most important Scottish difference. In Scotland, a beneficiary can legally witness a will without losing their gift. The restriction in s.15 Wills Act 1837 has no Scottish equivalent. However, using an independent witness is still strongly recommended to prevent later challenges to the testator's capacity or undue influence.

Scotland also has a notarial execution procedure for testators who are unable to sign — a solicitor or notary public can subscribe the will on behalf of the testator.

If you are making a Scottish will, ClearWill's Scottish will service covers these jurisdiction-specific requirements.

Northern Ireland

Northern Ireland follows rules broadly similar to England and Wales. The governing legislation is the Wills and Administration Proceedings (NI) Order 1994.

• Two witnesses are required, both present simultaneously.
• The beneficiary restriction applies — a beneficiary who witnesses loses their gift.
• Witnesses must be 18 or over and of sound mind.
• Remote witnessing is not permitted.

ClearWill's Northern Ireland will service generates documents specific to NI law.

Special Circumstances

Armed Forces — Privileged Wills

Members of the armed forces on actual military service (and sailors at sea) can make a "privileged will" under the Wills Act 1837. These informal wills require no witnesses and can even be verbal. The privilege applies regardless of age — a soldier under 18 can make a privileged will. However, the privilege only applies during actual service; on return to civilian life, a properly executed will should be made.

Hospital and Care Home Wills

There is no rule preventing hospital staff or care home employees from acting as witnesses. However, proceed with caution. If staff are also beneficiaries (unusual but possible, for example in the case of a small bequest), their gift is voided. More importantly, a will signed in a hospital or care home is statistically more likely to face a challenge on capacity grounds — the testator's mental state at the time will be scrutinised. Having independent witnesses rather than care staff reduces this risk.

Video Witnessing (Not Valid)

Since 1 February 2024, witnessing via video call is not valid in England, Wales, or Northern Ireland. Scotland did not adopt the temporary video witnessing provision. Any will witnessed remotely since that date is not validly executed.

What If Witnessing Was Done Incorrectly?

The options depend on the nature of the error and whether the testator is still alive:

If the testator is alive: Make a new will. This is the cleanest solution. A fresh will, properly executed with two independent witnesses, supersedes the defective one. Alternatively, if the only issue is a beneficiary-witness, the testator can execute a codicil (an amendment to the will) that re-gifts the inheritance to the affected beneficiary — but this must itself be properly witnessed by two independent people.

If the testator has died: Options are limited. The defective will can be challenged in court, and where execution was fundamentally flawed (for example, only one witness), the court may declare it invalid entirely — meaning the estate passes under intestacy. In beneficiary-witness cases, the will itself stands but the affected beneficiary's gift is void; they cannot recover it through the courts.

The lesson is clear: get the witnessing right at the time of execution. It takes five minutes. Undoing a witnessing error after the fact is expensive, slow, and often impossible.

Frequently Asked Questions

Can a family member witness a will in the UK?

Yes — provided they are not a beneficiary and not married to a beneficiary. The restriction is about financial interest, not family connection. A sibling or adult child who receives nothing under the will can validly witness it.

Can a beneficiary witness a will?

Not safely in England, Wales, or Northern Ireland. Under s.15 Wills Act 1837, the will remains valid but the beneficiary-witness loses their gift entirely. In Scotland, there is no such restriction — a beneficiary can witness without consequence.

How many witnesses does a will need in the UK?

Two in England, Wales, and Northern Ireland — both present simultaneously. One in Scotland. A Scottish holograph will (entirely handwritten and signed) requires no witness.

Can a solicitor witness a will?

Yes, provided they are not a beneficiary. But there is no requirement to use a solicitor — any independent adult aged 18 or over (16 in Scotland) qualifies.

What happens if only one person witnesses a will in England and Wales?

The will is not validly executed and has no legal effect. The estate passes under intestacy rules. The solution, while the testator is alive, is to make a new will properly executed before two independent witnesses.

Can a will be witnessed over video call?

No. The COVID-era video witnessing provision expired on 31 January 2024. Since 1 February 2024, all wills in England, Wales, and Northern Ireland require in-person witnessing.
