Will Witnesses UK (2026): Who Can and Cannot Witness a Will — The Rules That Make or Break Validity

To witness a will in England and Wales, a person must meet the following requirements: (1) AGED 18 OR OVER: there is no specific age requirement stated in the Wills Act 1837, but a witness should be an adult of full legal capacity — in practice 18 or over. Courts have accepted witnesses aged under 18 in limited circumstances, but this should be avoided. A child cannot give meaningful evidence of due execution; (2) MENTALLY CAPABLE: the witness must have sufficient mental capacity to understand what they are witnessing and to give evidence of it if required later. A person with severe dementia or psychosis who cannot understand the signing process is not a suitable witness; (3) ABLE TO SEE THE TESTATOR SIGN: a witness must be physically present and able to see the testator (will-maker) sign the will. A blind person cannot witness a will because they cannot see the act of signing — though they can be a testator under a will read to them; (4) NOT A BENEFICIARY OR THE SPOUSE/CIVIL PARTNER OF A BENEFICIARY: this is the critical rule most frequently breached by people drafting their own wills. Under Wills Act 1837 s.15, if a witness is: (a) a beneficiary under the will (someone receiving a gift or legacy); (b) the spouse or civil partner of a beneficiary; their gift under the will is VOID — even though the will itself remains valid. The beneficiary-witness does not inherit. Note: this only applies to attestation at the time of execution — a beneficiary who witnesses a codicil does not lose their legacy under the original will; (5) NOT THE PERSON WITH WHOM THE TESTATOR HAS A CIVIL PARTNERSHIP CREATED AFTER THE WILL: a civil partner created after the will's execution does not affect the witness rules at the time of execution; (6) PRACTICALLY SUITABLE: two reliable adult witnesses who have no financial interest in the estate are the safest choice. The solicitor's receptionist; a neighbour; a colleague; a GP (in hospital wills) — all commonly used and entirely appropriate.

The formal requirements for executing a valid will are set out in Wills Act 1837 s.9 (as amended by the Administration of Justice Act 1982): (1) THE WILL MUST BE IN WRITING: a will must be in writing (typewritten or handwritten) — oral ('nuncupative') wills were abolished for civilians by the Wills Act 1837, subject to very limited exceptions for military personnel on active service; (2) THE TESTATOR MUST SIGN: the testator must sign the will with the intention of giving effect to it. 'Signature' includes: (a) any mark (e.g. an 'X') that is intended as a signature; (b) a rubber stamp signature; (c) a signature made by another person in the testator's presence and at their direction (if the testator is physically unable to sign). The signature should be at or after the end of the will — a signature appearing above the text may be ineffective; (3) THE TESTATOR MUST SIGN IN THE PRESENCE OF TWO WITNESSES: both witnesses must be SIMULTANEOUSLY present when the testator signs (or acknowledges their signature). The two witnesses can also sign on different occasions from each other — so long as each is present when the testator signs or acknowledges the signature; (4) BOTH WITNESSES MUST SIGN: each witness must sign the will in the testator's presence (after the testator has signed). The witnesses do not need to be present at the same time as each other — just each present when the testator signs/acknowledges; (5) NO REQUIREMENT FOR WITNESSES TO READ THE WILL: the witnesses do not need to know what is in the will. They simply attest that they saw the testator sign (or acknowledge their signature). Confidentiality of the will's contents is therefore preserved during execution; (6) NO NOTARISATION REQUIRED: unlike in many civil law countries, UK wills do not require notarisation. Two adult lay witnesses are all that is required; (7) THE ATTESTING CLAUSE: although not a legal requirement, the 'attesting clause' at the end of the will ('Signed by the above-named testator in our presence and by us in his/her presence') raises a rebuttable presumption of due execution — it is strongly recommended for all wills.

Yes — under Wills Act 1837 s.15, if a beneficiary (or the spouse or civil partner of a beneficiary) witnesses the will, their gift is void: (1) THE s.15 RULE — GIFT IS VOID, NOT THE WILL: the key point is that section 15 makes the GIFT void — not the will itself. The will remains valid and takes effect; the beneficiary-witness simply loses their inheritance. If the gift to the beneficiary-witness was the entire residuary estate, they inherit nothing; if it was a specific pecuniary legacy (e.g. £5,000), they lose that legacy but the rest of the will stands; (2) SPOUSE OR CIVIL PARTNER RULE: this catches not just the beneficiary themselves but their spouse or civil partner. If a beneficiary's husband witnesses the will, the beneficiary loses her legacy even though she did not witness the will herself; (3) THE PRACTICAL TRAP: the most common scenario is a married couple making wills and witnessing each other's wills. If husband and wife both make mirror wills leaving everything to each other, and they each sign as witnesses for the other's will, each loses their legacy under the other's will (because a beneficiary's spouse cannot witness). The wills are valid — but the spousal gifts are void. The estate then falls to the residuary beneficiaries (often the children) immediately, even if the surviving spouse is alive; (4) CHILDREN AS WITNESSES: if an adult child inherits under the will and witnesses it, their inheritance is void. This is a frequent DIY error; (5) IF THERE IS NO RESIDUARY GIFT TO FALL BACK ON: if the beneficiary-witness's gift is the only dispositive provision in the will (e.g. the entire estate is left to the beneficiary-witness alone and they inherit nothing), the residue passes on partial intestacy; (6) CODICIL ATTESTATION: a codicil (amendment to a will) that is witnessed by a beneficiary makes that codicil's gift void. But if the codicil does not create new gifts — merely confirming the existing will — and the beneficiary's gift is in the original will, the original gift is not affected by them witnessing the codicil; (7) REMEDY: if a beneficiary has already witnessed a will and the testator is still alive, the solution is simple — make a new will (or codicil) with independent witnesses. The problem is only irreversible after the testator's death.

A neighbour, GP, care home manager, or almost any independent adult can legally witness a will. However, there are practical and evidential considerations for vulnerable testators: (1) WHO MAKES A GOOD WITNESS IN PRACTICE: (a) neighbours — ideal; have no financial interest; can be tracked down later to confirm execution; (b) work colleagues — appropriate; (c) solicitors' staff — common in professional will drafting; (d) GPs and medical professionals — suitable from a legal standpoint; increasingly important for complex cases (see below); (e) bank staff — suitable; (2) THE 'GOLDEN RULE' — GP AS WITNESS FOR ELDERLY OR VULNERABLE TESTATORS: in Re Simpson [1977], the court expressed the view (obiter) that where there is doubt about testamentary capacity, the 'golden rule' is that the will should be witnessed by — or at least discussed with — the testator's GP before execution. Although not a legal requirement, following the golden rule provides strong evidence that the testator had capacity at the time of execution, making it much harder to challenge the will later on grounds of lack of testamentary capacity; (3) HOSPITAL WILLS: a will signed in hospital can be witnessed by any two adults — a nurse, a visitor, a hospital chaplain. The hospital has no obligation to provide witnesses. In urgent cases, the nurse and another staff member typically serve as witnesses; (4) CARE HOME WILLS: care home staff can witness wills in theory, but care home managers should be cautious about witnessing a resident's will where: (a) the care home or its staff might benefit from the will; (b) there is any pressure or influence from family members; (c) the resident has fluctuating capacity. Good practice is to use independent witnesses and, where capacity is in doubt, involve the GP; (5) REMOTE WITNESSING: temporary COVID regulations allowed remote witnessing (via video link) of wills signed between 31 January 2020 and 31 January 2024. These regulations have now EXPIRED. As of 2026, wills must be executed with both witnesses physically present — not via video link.

DIY will writers frequently make witnessing errors that invalidate the will or void gifts: (1) ONLY ONE WITNESS: a will signed by only one witness is not validly executed — the will is invalid and the estate passes on intestacy. Both witnesses must sign; (2) BENEFICIARY AS WITNESS — GIFT VOID: as described above, a beneficiary (or their spouse/civil partner) witnessing a will makes their gift void. The most common error: children who inherit witness their parent's will; a spouse witnesses the other spouse's will; (3) WITNESSES NOT PRESENT SIMULTANEOUSLY WHEN THE TESTATOR SIGNS: both witnesses must be present when the testator signs (or acknowledges their signature). If Witness A watches the testator sign and then leaves, and Witness B signs later without having been present for the testator's signature, the will is not properly executed. All parties should be in the same room at the same time; (4) TESTATOR DOES NOT SIGN IN PRESENCE OF WITNESSES: the testator cannot sign the will privately and then bring it to two people to witness. Either: (a) the testator signs with both witnesses present; or (b) the testator shows the witnesses a pre-signed will and acknowledges 'this is my signature' in the presence of both witnesses simultaneously — this acknowledgement is treated as signing in their presence; (5) SIGNATURE BEFORE THE DISPOSITIVE PROVISIONS: if the testator signs in the middle of the will or above the main text, gifts below the signature may be void. The signature should be at or after the end of the will; (6) WITNESSES SIGN ON DIFFERENT OCCASIONS FROM EACH OTHER WITHOUT THE TESTATOR PRESENT: a witness must sign in the testator's presence. If Witness A signs the will on Monday while the testator is present, and Witness B signs on Tuesday without the testator being present, the execution is defective; (7) CODICILS IMPROPERLY WITNESSED: a codicil amending a will must be executed with the same formalities as the original will — two witnesses, in the testator's presence. An unwitnessed or poorly witnessed codicil is invalid; (8) THE SOLUTION: use two independent adult witnesses with no financial interest in the estate; have all three parties present at the same time; use the standard attesting clause; and keep a note of who the witnesses were (name, address, occupation) with the will.
